Yale Psychiatry Grand Rounds: April 29, 2022

 .
  • 00:00Q All for being here this morning
  • 00:02and to for the opportunity to
  • 00:05present in today's grant rounds.
  • 00:07It's my great honor.
  • 00:08The topic that I would like to
  • 00:10highlight today is the emergence of
  • 00:12the field of cardiac psychology and
  • 00:14to make a case how we should broaden
  • 00:17it to include vascular populations and
  • 00:20how both cardiac as well as vascular
  • 00:23populations all would benefit from
  • 00:25integrated cardiovascular, behavioral
  • 00:27healthcare in the specialty setting.
  • 00:31These are my disclosures.
  • 00:36I would like to dedicate today's
  • 00:38lecture to my great mentor,
  • 00:40alluded to in the introduction,
  • 00:43who has been a great support
  • 00:44throughout my career.
  • 00:45Yohan done on it also
  • 00:47Belgian native like myself.
  • 00:49Whose theory focused on a
  • 00:52combination of personality traits
  • 00:53that proved to be particularly
  • 00:56toxic for cardiovascular outcomes.
  • 00:58Without his encouragement and support,
  • 01:00I would not stand here today and so
  • 01:03his work and passion for the field
  • 01:06has definitely been passed on to
  • 01:08many of us who have spread out and
  • 01:10trained under him and all of us have
  • 01:13spread out over the world to continue
  • 01:15the the work that is ahead of us.
  • 01:20So for today's presentation,
  • 01:22I would like to take you back to
  • 01:25some of the origins of health,
  • 01:28psychology and some of the defining
  • 01:31moments as a response to the
  • 01:33post war chronic disease burden.
  • 01:35And following that I would like to
  • 01:37zoom in on further subspecialization
  • 01:39that occurred and as an example would
  • 01:42like to highlight the feel of cardiac
  • 01:45psychology and the research and the
  • 01:47interventions that led up to it.
  • 01:49Next I would like to broaden the
  • 01:51focus to include populations with
  • 01:53vascular disease and those as those
  • 01:56have been the primary focus of
  • 01:58our work and I will conclude with
  • 02:00making the case for integrated
  • 02:02behavioral health care for both
  • 02:04cardiac and vascular populations.
  • 02:09So before we dive back in history,
  • 02:12I want to highlight what the
  • 02:15American Psychological Association
  • 02:16today defines as health psychology.
  • 02:19They defined as discipline as a discipline
  • 02:23that examines how biological, social,
  • 02:26and psychosocial factors influence
  • 02:28health but also illness and health.
  • 02:31Psychologists use their psychological
  • 02:33signs to promote health to prevent
  • 02:36illness and improve healthcare systems.
  • 02:38So I want you to keep in mind that
  • 02:41definition as we dive into today's lecture.
  • 02:46So some of the historical origins of the
  • 02:48field are traced back to the post World
  • 02:51War Two period where how psychology
  • 02:54really emerged as a reaction to some
  • 02:58of the changing phenomena in society.
  • 03:02First of all,
  • 03:02we saw a decline of infectious diseases,
  • 03:05but at the same time also a rise of chronic
  • 03:07conditions due to the changed lifestyle,
  • 03:10working and living conditions in the
  • 03:14populations in industrialized nations.
  • 03:17And the origins of health psychology
  • 03:21technically can be traced back
  • 03:23in in the US to this publication
  • 03:26of Williams Schofield in 1969,
  • 03:28where the Roll of Psychology in the
  • 03:31delivery of health services was a
  • 03:34report that was published by the
  • 03:37American Psychological Association
  • 03:39in the American psychologist.
  • 03:41And all over the world we saw
  • 03:44similar developments taking place,
  • 03:46and as an example,
  • 03:47French psychology after World War Two.
  • 03:50Increasingly clinical psychology was
  • 03:52being delivered in health settings.
  • 03:55It was influenced by psychoanalysis,
  • 03:59social and clinical psychology
  • 04:01and psychopathology,
  • 04:02and so this blend,
  • 04:03in addition with the influence of
  • 04:06American social psychology,
  • 04:08social cognitive theories of health
  • 04:10and illness.
  • 04:11Brought it together to this health
  • 04:14psychology field that emerged.
  • 04:16And increasingly,
  • 04:17this new discipline was being disseminated
  • 04:20in the hospital setting and in the public
  • 04:23health sphere and all around the world.
  • 04:25We saw similar developments taking place,
  • 04:27such as in the UK,
  • 04:29Brazil, South Africa,
  • 04:30the Netherlands, Australia,
  • 04:31and elsewhere.
  • 04:36Other key critical developments that
  • 04:39allow this new discipline to emerge is
  • 04:42really a variety and and a fortunate
  • 04:45set of circumstances and and critical
  • 04:48breakthroughs down to we saw evolve.
  • 04:51So first of all, we had high-quality
  • 04:54epidemiological evidence how behavior
  • 04:56and disease incidents were causally
  • 04:58related and the most prominent
  • 05:00example of that is smoking behavior
  • 05:03and the incidence of lung cancer.
  • 05:06So that is an important development
  • 05:08that took place and then with the
  • 05:11rise of the chronic health burden.
  • 05:13Of course came also the rise of the
  • 05:15cost of healthcare and the need for
  • 05:17more effectiveness and efficiency in
  • 05:19the delivery of health care and health.
  • 05:21Ecology was one of the responses to that.
  • 05:25At medical schools we saw also an
  • 05:27uptake in teaching of behavioral
  • 05:30sciences as a part of the curriculum
  • 05:32and an increase in communication skills
  • 05:36training to improve patient adherence,
  • 05:38patient satisfaction satisfaction.
  • 05:40So an increased focus and an openness to
  • 05:44that in the medical schools was taking place.
  • 05:47We saw more and more clinical psychology
  • 05:50behavioral medicine also moving
  • 05:52into the primary care setting and
  • 05:54collaborative care models being offered.
  • 05:56During this era also we had important
  • 06:00theories for behavioral change
  • 06:02models being developed,
  • 06:03tested and used for interventions
  • 06:06with evidence based interventions
  • 06:08that we still use up until this day
  • 06:12that were developed during this period
  • 06:15and we actually became pretty good
  • 06:17in predicting health behavior change
  • 06:19with an emphasis on health beliefs,
  • 06:22attitudes and behavior.
  • 06:25And then another parallel of development
  • 06:28was the field of second neural immunology,
  • 06:31where we really saw the relationship
  • 06:33between the immune system and the
  • 06:36central nervous system and the role
  • 06:37of stress being documented in a in
  • 06:40a very detailed way,
  • 06:41and then finally unfortunately the
  • 06:43AIDS and HIV epidemic in the 80s.
  • 06:47Also spurred funding in behavioral
  • 06:49health research,
  • 06:50so those developments were critical
  • 06:53for this discipline to emerge.
  • 06:57Yale had a very important role also
  • 06:59in helping to shape this field of
  • 07:02health technology with yields,
  • 07:03President Peter Salovey being one of
  • 07:06the Inspirators who helped define the
  • 07:09field with others and highlighting the
  • 07:11fact that people sense of their own health,
  • 07:14is not only the reflection of their
  • 07:17psychological and physical well being,
  • 07:19but also a good predictor for
  • 07:22subsequent physical health and how
  • 07:24these two are are really intertwined.
  • 07:30Further formalization took
  • 07:32them place with in 1976.
  • 07:36The establishment of the Division
  • 07:3838 that was referred to in the
  • 07:41beginning of of the introduction.
  • 07:43Where the American Psychological
  • 07:45Association established a separate
  • 07:47division directed towards health psychology
  • 07:50and which is still up until today.
  • 07:52Very active.
  • 07:54You had also one of the foundational
  • 07:57conferences that really brought behavioral
  • 08:00health and biomedical scientists together.
  • 08:03How we should together solve
  • 08:05problems of health and illness
  • 08:07in an interdisciplinary way.
  • 08:09And this was led by Gary
  • 08:11Schwartz and Stephen Weiss.
  • 08:13And then in the early 80s,
  • 08:14the Arden House Conference really
  • 08:18scoped out the professional
  • 08:20responsibilities and the training
  • 08:22requirements for health psychologists.
  • 08:25So together these multidisciplinary
  • 08:27developments and professionals
  • 08:29promoted the importance of behavioral
  • 08:32health and and spurring more research
  • 08:34and education in this domain.
  • 08:40So in the next part I would like to zoom
  • 08:43in more on the further subspecialization.
  • 08:45Since this new discipline
  • 08:48emerged and the observations,
  • 08:50the research that led up to this,
  • 08:52and while not officially
  • 08:54recognized as a subspecialty,
  • 08:56it certainly is emerging and the relevance
  • 08:59of it has become increasingly clear.
  • 09:02So I'm talking about cardiac
  • 09:04psychology as people refer to it.
  • 09:08Also, a little bit of history here that
  • 09:11took place around the same time as health
  • 09:14psychology in general was developing,
  • 09:16taking us back to the work on
  • 09:18type A personality in which I will
  • 09:20talk a little bit more in a bit.
  • 09:22Going from type A personality
  • 09:26to elements of its personality,
  • 09:27anger, hostility, focusing,
  • 09:29then the next wave of research
  • 09:32on depression and the individual
  • 09:34elements of all the types of symptoms,
  • 09:38somatic versus cognitive,
  • 09:40in the toxicity of cardiovascular outcomes.
  • 09:44A related concept where the emphasis was
  • 09:47on fatigue was vital exhaustion that
  • 09:49was also coming from the Netherlands,
  • 09:52studied by apples in mass thrift and
  • 09:55for some of you might be familiar
  • 09:58with the mass Thrift Questionnaire
  • 10:00which was developed over there.
  • 10:02And then further research on
  • 10:05other psychosocial factors,
  • 10:06anxiety and of course a large
  • 10:08body of research on stress,
  • 10:10both acute and chronic stress that
  • 10:13was developed in highlighting.
  • 10:15Again the work of my mentor going
  • 10:18hunting led to a developed a theory and
  • 10:21described the phenomenon of the depressed,
  • 10:23the distressed type D personality,
  • 10:26which is a combination of
  • 10:28negative affectivity,
  • 10:29the tendency to experience negative emotions.
  • 10:32But at the same time,
  • 10:34also scoring high on social
  • 10:36inhibition so people not sharing
  • 10:38their emotions and he documented in
  • 10:42several cardiovascular populations
  • 10:43that that combination is particularly
  • 10:46cardiotoxic as as we refer to it.
  • 10:51So the first description that was
  • 10:54published and where we saw a parallel
  • 10:58trend between people's mindsets and
  • 11:01outcomes for coronary artery disease
  • 11:04was done by a UK physician in 1950.
  • 11:07Where there was a link.
  • 11:11Describe between potentially changing
  • 11:13lifestyle and working conditions
  • 11:15and cardiovascular disease.
  • 11:17And his first letter was met with highly
  • 11:22contested responses to these observations.
  • 11:25So the only thing that this doctor
  • 11:28Stewart noted was that there was an
  • 11:31increase in cardiovascular disease
  • 11:32coronary artery disease during
  • 11:34this century is what he describes,
  • 11:37and that the malady mostly effects men
  • 11:40in middle life and in his further the
  • 11:44scription he refers to the work pace
  • 11:46and notes a parallel between the two.
  • 11:52So that was the first publication in
  • 11:55the UK and then a little later in the US
  • 11:59there was a duel of cardiologists that
  • 12:03presented the work on type A personality,
  • 12:08and Rosamond and Friedman described
  • 12:11as type A personality that was
  • 12:15characterized by an intense Dr.
  • 12:18Need for achievement,
  • 12:19constantly being on the go.
  • 12:22Being very competitive.
  • 12:24Hostile and having high anger
  • 12:28and and and So what they observed
  • 12:32was in this personality profile.
  • 12:35When they contrasted it with other
  • 12:38personality profiles is that they had
  • 12:41a much higher rate of coronary artery
  • 12:43disease and also in their subsequent
  • 12:46work described higher mortality rates
  • 12:49linked with this personality profile.
  • 12:53This construct was only studied in men,
  • 12:56and as the research accrued.
  • 13:00There was some issues with
  • 13:03replication of this work and.
  • 13:06One started to focus on some of the
  • 13:08most toxic aspects of this personality.
  • 13:11Trade anger and hostility,
  • 13:14which then was studied in isolation.
  • 13:17And and so over time this this research
  • 13:19line had gotten out of favor because
  • 13:22there were several issues with it.
  • 13:24And so with that overall,
  • 13:26the study of psychosocial factors
  • 13:29in coronary artery disease.
  • 13:31The enthusiasm for it temporarily lowered.
  • 13:37Until this Canadian dual of researchers
  • 13:39were able to put the interest for
  • 13:42psychosocial factors and cardiac disease
  • 13:45back on the map with their landmark
  • 13:48study published in the 90s in in JAMA,
  • 13:51Nancy, Fraser, Smith and Plasma.
  • 13:54Let's billons they followed in Quebec.
  • 13:58A population of acute micro
  • 14:01cardial infarction survivors.
  • 14:0478% of them was male.
  • 14:07And they were interviewed with a
  • 14:10diagnostic interview for Depression 5
  • 14:12to 15 days following the acute event.
  • 14:15And they simply looked at their
  • 14:17survival state at six months
  • 14:19obtained from medical records.
  • 14:22And what they saw is that upon assessment,
  • 14:25when people had their acute
  • 14:28myocardial infarction,
  • 14:2916% met the criteria of major depressive
  • 14:33disorder at the time of the interview.
  • 14:35And then at follow-up,
  • 14:38the people who died 50% was
  • 14:42marked as depressed at inclusion.
  • 14:45And so the mortality in the press was
  • 14:48much higher than the non depressed.
  • 14:50And all of the mortality causes
  • 14:53were cardiac related.
  • 14:54So the risk that they observed was a
  • 14:57fourfold risk of adverse outcomes.
  • 15:00And so this really opened up this
  • 15:02line of research again and and
  • 15:05gotten a lot of attention.
  • 15:07Why?
  • 15:07Why is this a landmark paper,
  • 15:09even though today we would say this
  • 15:10is a small study, short follow-up,
  • 15:12etcetera.
  • 15:13It reopened a discussion of the
  • 15:16importance of psychosocial and behavioral
  • 15:18factors in cardiac disease outcomes.
  • 15:21And by focusing on depression
  • 15:23as opposed to personality,
  • 15:25it offered a manageable explanation,
  • 15:27for which we know treatments for the
  • 15:30mind body link in cardiac disease,
  • 15:32and importantly this this work for the
  • 15:34first time did not have a gender bias.
  • 15:36It also included women.
  • 15:38And it also offered an important concept
  • 15:42that could serve as an explanation
  • 15:45for the racial and gender disparities
  • 15:47that were Dan already described
  • 15:49in in cardiac disease outcomes.
  • 15:53So since then, people have further
  • 15:56looked at much larger cohorts.
  • 15:582000 plus cohorts in in
  • 16:01a variety of populations,
  • 16:03stable coronary artery disease.
  • 16:07As well as outpatients
  • 16:09heart failure patients.
  • 16:11Longer follow-up periods and.
  • 16:14Essentially,
  • 16:15these these observations
  • 16:16were replicated further,
  • 16:18and then the endpoints that one
  • 16:22became attuned to was expanded
  • 16:24not only to focus on mortality,
  • 16:28but especially the quality of life.
  • 16:30Of these patients that go
  • 16:32through this experience,
  • 16:33adherence issues and lifestyle factors
  • 16:36were also related to the study of
  • 16:39depression in in this population.
  • 16:47The numbers for today that I would
  • 16:51like to highlight that overall we we
  • 16:54find evidence for acute myocardial
  • 16:57infarction survival survivors.
  • 16:59That's about one in five percents
  • 17:01with a major depressive disorder.
  • 17:03And one in three does not meet the
  • 17:07threshold for major depressive disorder,
  • 17:10but still presents with clinically
  • 17:12relevant depressive symptoms,
  • 17:14and it doesn't matter whether people
  • 17:16meet the formal threshold or have
  • 17:19increased depressive symptoms.
  • 17:20They are at risk of subsequent
  • 17:23adverse outcomes, and that has
  • 17:25been multiple times demonstrated.
  • 17:27Unfortunately,
  • 17:28only a third of patients are recognized
  • 17:31as such as depressed during their
  • 17:34acute myocardial infarction admission
  • 17:36even when systematic screening
  • 17:39programs in hospitals are in place.
  • 17:42We do find that there is a large
  • 17:45under recognition of depression,
  • 17:47and the problem is also tied to
  • 17:49the care linkage and the linking
  • 17:52them to appropriate treatment.
  • 17:58Next, I want to highlight a larger global
  • 18:02study that has since then been conducted
  • 18:05and was published in The Lancet in 2004,
  • 18:09which caught a lot of attention in
  • 18:13the space of cardiology and allied.
  • 18:17Specialties that are interested
  • 18:19in cardiovascular populations,
  • 18:20and this was a case control design
  • 18:23where they studied over 11,000
  • 18:26patients who had suffered their first
  • 18:30heart attack and they matched them
  • 18:33with age and sex matched controls.
  • 18:37Control set of over 13,000 individuals.
  • 18:41And they recruited them from
  • 18:44centers around the world, Asia,
  • 18:46Europe, Middle East, Africa,
  • 18:47Australia and North and South America.
  • 18:50And then they measured
  • 18:51the variety of factors,
  • 18:53the risk factors that are known
  • 18:55to be associated with my cardio,
  • 18:57infarction and psychosocial
  • 18:59stress was one of them.
  • 19:01It was assessed with four simple questions
  • 19:04about stress at work and at home.
  • 19:06Financial stress and major life
  • 19:08events in the past year and then
  • 19:11additional questions also ask
  • 19:13people about the locus of control
  • 19:16and the presence of depression.
  • 19:18And here all of these factors that
  • 19:21they studied are listed together and
  • 19:24put together in a model where the
  • 19:27contribution of how much each individual
  • 19:30factor contributed to the risk of
  • 19:33acute myocardial infarction was presented.
  • 19:35Other risk factors studied were smoking,
  • 19:39diabetes,
  • 19:39hypertension, obesity,
  • 19:40intake of fruits and vegetables,
  • 19:44exercising alcohol intake and lipid profiles.
  • 19:48And so when you look at
  • 19:52the psychosocial index,
  • 19:53you see that it was a robust predictor of
  • 19:57experiencing and acute myocardial infarction.
  • 20:00And in this column they also calculated the
  • 20:04population attributable attributable risk,
  • 20:06which is the proportion of the
  • 20:09incidents of getting an AMI in
  • 20:12the population between those who
  • 20:14are exposed to particular risk
  • 20:17factors versus non exposed.
  • 20:19Is calculated and so if you focus
  • 20:23on the rate for women it has a
  • 20:27population attributable risk of 40%.
  • 20:30And so if you translate that that's 40,
  • 20:33it means that 40% of the incidence
  • 20:35of an acute myocardial infarction
  • 20:37in women is due to the exposure
  • 20:39of psychosocial risk factors.
  • 20:41So that was an eye opening study also
  • 20:43for the larger medical community to
  • 20:46acknowledge the role of psychosocial factors.
  • 20:49In cardiovascular disease and
  • 20:51in acute myocardial infarction,
  • 20:53in particular.
  • 20:56So with all this work and follow up,
  • 21:00it became clear that stress
  • 21:02is a significant risk factor
  • 21:03for coronary artery disease.
  • 21:05Both incidents and progression.
  • 21:06It is very common.
  • 21:08It can be confused with cardiac symptoms.
  • 21:10It is linked to behavioral and
  • 21:13cardiovascular risk factors,
  • 21:14and it really forms a barrier
  • 21:16for medical interventions.
  • 21:18And also sometimes it may be a
  • 21:20direct trigger for experiencing
  • 21:22acute cardiac events such as.
  • 21:25Anger has been linked with the
  • 21:28experience of an acute event.
  • 21:33Since this research was proposed,
  • 21:36many also studied underlying mechanisms
  • 21:39that would explain why stress is linked
  • 21:44to atherosclerosis and the following
  • 21:47model has been proposed as the underlying
  • 21:51stress model for cardiovascular disease.
  • 21:54Now with atherosclerosis as the
  • 21:58underlying pathological process,
  • 22:00so chronic stress and affective disorders
  • 22:03that lead to the activation of the HP
  • 22:07axis and the sympathetic nervous system.
  • 22:10And it further affects our behaviors,
  • 22:13how our health behaviors and and due to
  • 22:16the prolonged activation and the imbalance
  • 22:19of the sympathetic nervous system,
  • 22:21there are heightened
  • 22:23physiological responsiveness to,
  • 22:25to acute stressors.
  • 22:27Also interactions with chronic stressors
  • 22:29that further cause more downstream effects,
  • 22:33such as the ones listed on the right,
  • 22:36increased inflammation,
  • 22:37platelet reactivity and endothelial.
  • 22:40Dysfunction to name a few of those effects.
  • 22:46So following these insights,
  • 22:48people also came together to design several
  • 22:51interventions to address depression as a
  • 22:55risk factor for cardiovascular disease
  • 22:57and depression and stress reduction.
  • 22:59Interventions have been developed and
  • 23:02tested mostly in coronary populations and
  • 23:06the most prominent ones highlighted here.
  • 23:09And so these trials they overall were
  • 23:12successful in improving depression,
  • 23:14symptoms, quality of life.
  • 23:16But at the same time,
  • 23:19the hopes and the fields were high
  • 23:21also to be able to reduce adverse
  • 23:23cardiovascular events and which did not
  • 23:27materialize for many of these trials.
  • 23:30Often due to the ways the studies
  • 23:33were designed or powered, however,
  • 23:35this trial out of Sweden which focused
  • 23:39specifically on women who survived an
  • 23:42acute myocardial infarction or underwent
  • 23:45a major coronary revascularization.
  • 23:48They offered these women a program where
  • 23:53the focus was on psychoeducation stress
  • 23:57reduction through relaxation training,
  • 23:59self monitoring,
  • 24:01cognitive restructuring and to
  • 24:03realize a more adaptive coping skill
  • 24:06set when they were dealing with
  • 24:09family and work related stressors.
  • 24:11Ends simultaneously also focus on self care
  • 24:14and compliance with the medical regimen,
  • 24:17and so this trial did show a significant
  • 24:20survival effect that was actually
  • 24:22threefold in comparison with the
  • 24:25usual care for long term mortality.
  • 24:28So so these are some of the critical
  • 24:32trials that were conducted,
  • 24:36and our colleague Matthew Berg,
  • 24:39Dr Burke,
  • 24:39was also one of the key pioneers
  • 24:41of many of those.
  • 24:42Interventions that were tested
  • 24:45in coronary artery populations,
  • 24:48so all of these developments in
  • 24:52the cardiovascular population gave
  • 24:54rise to what we now today referred
  • 24:57to as cardiac psychology,
  • 24:59and it was described in in these works.
  • 25:02That that this is really a
  • 25:05subspecialization of health psychology.
  • 25:07And, as I mentioned,
  • 25:08colleague Doctor Matthew Burke
  • 25:10being one of the lead figures of
  • 25:13this subspecialization The EPA also
  • 25:15recognizes this term of cardiac psychology,
  • 25:19although it it does label it as
  • 25:22an emerging subspecialty.
  • 25:24So it's still very much under development.
  • 25:29So in what comes next?
  • 25:32I want to make the case that.
  • 25:34Hard mind and vascular really are so
  • 25:36intertwined that we should be looking
  • 25:38at the spectrum of cardiovascular
  • 25:40diseases and also when we think
  • 25:42about psychosocial factors and keep
  • 25:44that whole entire spectrum in mind.
  • 25:47And it also highlights the
  • 25:49need for further support.
  • 25:51Specialization and expansion.
  • 25:52Early insights in in these populations
  • 25:55and our treatment models and how we
  • 25:57translate them to clinical care.
  • 26:01As you all know, atherosclerosis is a
  • 26:05generalized disease and significant
  • 26:07atherothrombotic events may manifest
  • 26:10in different arteries of the body.
  • 26:14It may happen in in your carotid
  • 26:16artery in in lower extremity arteries,
  • 26:18and much of our work has focused on
  • 26:21on that lower extremity population,
  • 26:23peripheral artery disease,
  • 26:24or PAD as one refers to.
  • 26:27And it is often still a very
  • 26:31underrecognized condition,
  • 26:31for which there is great unawareness
  • 26:34and also under treatment.
  • 26:35And what we see is that the
  • 26:38cardiovascular event rates are
  • 26:40often worse than as we see for
  • 26:43coronary populations because.
  • 26:44That field has progressed so much
  • 26:47further and risk management and
  • 26:49and recognition and population
  • 26:51awareness as opposed to other.
  • 26:54Atherothrombotic diseases on
  • 26:55the cardiovascular spectrum.
  • 26:59Before I highlight on PED,
  • 27:01I also want to make a mention
  • 27:04of the REACH registry,
  • 27:06which was another big global study,
  • 27:09a landmark study that studied the spectrum
  • 27:13of atherosclerosis in a global setting.
  • 27:17And the strength of that study was that
  • 27:20it it focused on coronary artery disease,
  • 27:23peripheral artery disease,
  • 27:24and cerebrovascular disease,
  • 27:25but really demonstrated that these are
  • 27:28manifestations of the same process.
  • 27:31Many people have overlapping disease,
  • 27:33and it also contrasted some of the
  • 27:37differences in outcomes and under
  • 27:39treatment for these conditions.
  • 27:42So there was also a cohort of PD patients,
  • 27:44and as you see there is much overlap
  • 27:47with coronary artery disease as
  • 27:48well as cerebrovascular disease.
  • 27:50So patients may never present
  • 27:52with with an isolated condition.
  • 27:54There's always that broader conglomerate
  • 27:56of risk that we need to be in mind,
  • 28:00and it depends on where the
  • 28:03atherothrombotic events manifest
  • 28:05first as to what you're presenting.
  • 28:09Complaint is and how you entered
  • 28:11the system for cardiovascular care.
  • 28:17So the PD disease burden to give you
  • 28:21an idea when people present with PD is
  • 28:24it's often a marker of very aggressive
  • 28:28generalized atherosclerotic disease.
  • 28:30And resulting in in reduced what
  • 28:33filling their leg arteries and over 200
  • 28:37million people are affected globally.
  • 28:39And in the US alone,
  • 28:41we have a population of over 8,000,000,
  • 28:45and so it's on the rise in both high income
  • 28:47and low income and middle income countries.
  • 28:49Both men and women.
  • 28:51And it's rapidly growing due to the
  • 28:53aging population and steady increase in
  • 28:56obesity and diabetes rates and and so
  • 28:58it's a serious public health problem.
  • 29:02Katie can present as a
  • 29:05spectrum of manifestations.
  • 29:07There's people who don't know
  • 29:09they have it but and are labeled
  • 29:12as asymptomatic when they do
  • 29:15undergo noninvasive testing.
  • 29:17They might see that there's
  • 29:18reduced Platt flow,
  • 29:19but do not present with active symptoms.
  • 29:23And often that is because
  • 29:26of a sedentary lifestyle.
  • 29:28But these patients are also at
  • 29:30risk of having adverse outcomes
  • 29:32and then further down the spectrum.
  • 29:35There are symptomatic manifestations,
  • 29:37pain while walking that has a different.
  • 29:41Gradations of severity and then
  • 29:43towards the end we have critical limb
  • 29:46ischemia manifestations where the
  • 29:48limb is really in danger and people
  • 29:51are dealing with non healing wounds,
  • 29:54wounds and a high risk of amputation.
  • 29:57So people if patients present with PD
  • 30:00in spite of optimal medical management,
  • 30:04the residual risk for major adverse
  • 30:07cardiovascular events and live
  • 30:09events is about 5 to 10% per year,
  • 30:11which is pretty high.
  • 30:13If we look at critical limits,
  • 30:14chemia one in five has does not
  • 30:19survive at 6 to months to a year
  • 30:22and about half of the patients
  • 30:24would seali does not survive.
  • 30:27At five years.
  • 30:28It is also very costly and most
  • 30:31of the expenditures are incurred
  • 30:33for people's inpatient care,
  • 30:35which often consists of a lot of repeat
  • 30:41revascularizations and complicated stays.
  • 30:44Same risk factors as the
  • 30:46coronary artery disease.
  • 30:48However,
  • 30:48smoking,
  • 30:49obesity,
  • 30:49and aging are one of the more
  • 30:54prominent ones as well as
  • 30:56diabetes and a lot of people with
  • 31:00this condition also develop.
  • 31:02Chronic kidney disease.
  • 31:04And so the disease profile
  • 31:07is fairly complex.
  • 31:10So despite the magnitude of the
  • 31:12problem and the role of lifestyle
  • 31:14factors also for this condition,
  • 31:16there's only been recent interest
  • 31:18that there has been a focus on studies
  • 31:21psychosocial factors in this condition,
  • 31:23with most of the work highlighting
  • 31:26the role of depression and in this
  • 31:28illustrating that the prevalence really
  • 31:30is very similar to the ones reported
  • 31:33in coronary artery disease populations,
  • 31:35both in stable populations as well
  • 31:37as in people undergoing procedures,
  • 31:39as demonstrated. Year across these cohorts.
  • 31:45Also concerning is that in the US
  • 31:48this is a sample that we studied a
  • 31:52national sample of inpatient admissions.
  • 31:55Where we see a rise in those admissions over
  • 31:59the last decade for critical limits chemia,
  • 32:02the most severe manifestation.
  • 32:04And what we see is that the most rapid
  • 32:08increase in those admissions take
  • 32:10place in populations younger than 65.
  • 32:14You see the squares here representing
  • 32:17men below 65, and then also rapid
  • 32:21uptake in women of below 65 years,
  • 32:23which is very typical of how we know it,
  • 32:27because typically it is disease
  • 32:30presents in older populations.
  • 32:32And then with those admissions,
  • 32:34one in five admissions is characterized with
  • 32:37a comorbid anxiety and depression diagnosis,
  • 32:40and these are recognized diagnosis.
  • 32:42So possibly only representing
  • 32:44the tip of the iceberg.
  • 32:46But here we also see a steady
  • 32:49increase over time in the last
  • 32:52decade for both PD and and CLI.
  • 32:54Which may be related to the younger
  • 32:57population that is is affected by
  • 33:00these admissions or better recognition,
  • 33:02or a true greater prevalence,
  • 33:04and that we don't know.
  • 33:07And if we zoom in on the risk
  • 33:09profile of these patients,
  • 33:11we see that underrepresented minorities.
  • 33:15People without insurance are more likely
  • 33:18to represent it in the younger group,
  • 33:21and they also present with lower
  • 33:24household income, more diabetes.
  • 33:28Obesity prior amputation,
  • 33:30addiction and mood disorders,
  • 33:33and this is a profile that we
  • 33:35really don't see as much reoccurring
  • 33:38in the older populations.
  • 33:42Recognize depression in patients
  • 33:44with Celine during an admission
  • 33:46is also associated with a higher
  • 33:49odds of undergoing and imputation,
  • 33:51both for endovascular procedures
  • 33:53presented here on the left and
  • 33:56surgical revascularization.
  • 33:58And so whether this is
  • 33:59constantly related or not,
  • 34:00the fact is that people who
  • 34:03who go through this experience
  • 34:05are much more likely to also
  • 34:07copresent with a major depression.
  • 34:10Depression.
  • 34:13In this same cohort,
  • 34:15we demonstrated that having
  • 34:18comorbid depression translated
  • 34:20into a longer length of stay,
  • 34:22both for endovascular procedures
  • 34:23as well as surgical procedures,
  • 34:25and it also results in higher
  • 34:28total charges for their states are
  • 34:31really it is a group that warns
  • 34:34more care and has is at risk of
  • 34:37more complex disease outcomes.
  • 34:43When we pull all the work done in PD
  • 34:46together on the risk factor of depression,
  • 34:48which we recently did with this
  • 34:50meta analysis in our group,
  • 34:52we see a definite trend emerging for
  • 34:55an association between depression and
  • 34:57mortality as we see in the top panel for
  • 35:00major adverse live events and amputation.
  • 35:02Unfortunately, there is still a possibility
  • 35:04of data out there to show that link,
  • 35:07but we do see announcing a nonsignificant
  • 35:10trend towards higher risk emerging.
  • 35:15Making a switch now to the portrait
  • 35:17registry work that we have done
  • 35:20where we followed people with a new
  • 35:22diagnosis of PTSD and who presented at
  • 35:25vascular clinics and sought out care
  • 35:28at their vascular specialty clinic in
  • 35:31the US and Netherlands and Australia.
  • 35:34So we see that 35% either presents with a
  • 35:39positive screen on depressive symptoms,
  • 35:41anxiety, or perceived stress upon arrival.
  • 35:45And a year following one in five
  • 35:48unique patients still score high on
  • 35:51either one of those questionnaires
  • 35:53for those depressive symptoms,
  • 35:56anxiety and perceived stress.
  • 35:59So people do.
  • 36:00Report these symptoms as they navigate
  • 36:03their care and zooming in on the
  • 36:06experience of stress for this population.
  • 36:09When people report increase scores
  • 36:11for perceived stress at 2 subsequent
  • 36:14times as they are navigating their
  • 36:17care within that study, we.
  • 36:20Linked that with their long term
  • 36:22survival and what we see is that
  • 36:25in the four year subsequent to
  • 36:27receiving care for PD,
  • 36:28those who reported the
  • 36:29highest trust experiences.
  • 36:30They also have much higher.
  • 36:34Mortality rates over the long
  • 36:38term observation period.
  • 36:40Same what we see in the disease,
  • 36:43specific health status and
  • 36:46trajectory of these patients.
  • 36:48People in blue are the ones who
  • 36:51represent those with chronic stress
  • 36:54experiences and their health status
  • 36:56scores are mapped out over the
  • 36:58year of their treatment and what
  • 37:01we see is that the differences
  • 37:03accomplished between distressed
  • 37:04and non distressed populations is
  • 37:06exceeding 3 times the minimally
  • 37:08clinically important difference.
  • 37:10Overdose health status outcomes.
  • 37:12So really very impactful and detrimental
  • 37:15to their PD rehabilitation trajectory.
  • 37:21We then further looked at two
  • 37:23who was experiencing these
  • 37:25chronic stress experiences,
  • 37:26and we found that these chronic stress
  • 37:30experiences can be reliably predicted.
  • 37:33We assessed their stress at baseline 1/6
  • 37:36and 12 month follow up and we did that
  • 37:40in acute myocardial infarction cohort,
  • 37:43which was our derivation cohort
  • 37:45for developing this model and we
  • 37:48validated our model in the PD
  • 37:50cohort that I just described.
  • 37:52And again, chronic stress was
  • 37:54defined as A at least two follow-up
  • 37:58assessment periods with exceeding
  • 38:01scores above the population norms.
  • 38:05Factors that explain people's chronic stress,
  • 38:08experiences and the predictive
  • 38:11probability was 77% for the model
  • 38:14that we developed and younger age
  • 38:17female sex and socioeconomic factors.
  • 38:21Economic hardship in particular,
  • 38:23access to care barriers and low social
  • 38:26support really explained why people of
  • 38:29course were experiencing this chronic stress.
  • 38:32Knowing that this population
  • 38:34is so much affected by it,
  • 38:36this is important treatment information
  • 38:39to integrate as people get offered
  • 38:44expensive procedures and and complicated
  • 38:47disease management trajectories.
  • 38:51And then lastly I want to highlight how
  • 38:54depression and stress in PD populations may
  • 38:57relate to their physical activity levels,
  • 38:59and that's that concludes the portrait
  • 39:03data that I wanted to highlight.
  • 39:06The cornerstone of PD management at class.
  • 39:09One recommendation is that people
  • 39:11get off for walking therapy and they
  • 39:14are encouraged to walk three times
  • 39:16a week for at least 30 minutes.
  • 39:18To stimulate their cardiovascular
  • 39:20fitness and growth of collaterals.
  • 39:22To improve the provision in their legs.
  • 39:25In portrait, we had the depression,
  • 39:27perceived stress,
  • 39:28repeated assessments available,
  • 39:30but we also had repeated assessments
  • 39:33for physical activity and we took
  • 39:36the same questions as were done
  • 39:38for the inter heart study.
  • 39:40The global study where we could
  • 39:43rank people as sedentary,
  • 39:45engaged in wild activity
  • 39:48or strenuous exercise.
  • 39:51And here are the levels of depression
  • 39:53and stress in those line graphs and
  • 39:56then the bar charts really present
  • 39:59the sedentary behavior levels and you
  • 40:01can see that this is very high upon
  • 40:05presentation with a new diagnosis,
  • 40:0744% of reports being sedentary at baseline.
  • 40:11And even though those levels
  • 40:12go down over time,
  • 40:13they still remain pretty high.
  • 40:17And when we tried to reconstruct the
  • 40:21causal pathways of stress and physical
  • 40:23activity in PV with generalized
  • 40:26structural equation modeling,
  • 40:27we see that stress at the
  • 40:30top here and lowered physical
  • 40:32activity reinforce each other,
  • 40:35and we see bidirectional relations emerge,
  • 40:39meaning that a decrease in physical
  • 40:41activity results in higher stress
  • 40:43experiences and higher stress
  • 40:45experiences result in decreased.
  • 40:47Physical activity which is a
  • 40:50problem for the management of
  • 40:52of these patients and disease.
  • 40:55For the pression,
  • 40:56we see a slightly different picture,
  • 40:58and as you can see the
  • 41:01following strong trends emerged.
  • 41:03Patients who lower their level of physical
  • 41:08activity at baseline or then result.
  • 41:11Subsequently they present with
  • 41:14higher levels of depression and
  • 41:16these effects are reinforced further
  • 41:19downstream of the PD rehab trajectory.
  • 41:22Underscoring that.
  • 41:23Again,
  • 41:23the role of physical activity and the
  • 41:27risk of depression go hand in hand and.
  • 41:31Need to be seen together as
  • 41:34as one manages this disease.
  • 41:37So the key takeaways from this line
  • 41:40of research are, not surprisingly,
  • 41:42that depression and perceived stress
  • 41:44are very common in PD that PD and
  • 41:47overall is on the rise with increasingly
  • 41:50complex patient profiles and people
  • 41:53presenting with more severe disease
  • 41:56and a rapid growth in younger populations.
  • 41:59Number two,
  • 42:00what I like to highlight is that it is
  • 42:03associated with increased mortality,
  • 42:05poor PD, health status,
  • 42:07recovery trajectories,
  • 42:08higher cost and longer admissions and #3.
  • 42:12We do know who is at risk
  • 42:14of high stress experiences,
  • 42:15and we also know that it is.
  • 42:19Very much intertwined with people's
  • 42:21levels of physical activity,
  • 42:23which is part of of the cornerstone
  • 42:27of PD management,
  • 42:28behavioral activation and and.
  • 42:31Physical activity to achieve successful
  • 42:35outcomes and stress and depression
  • 42:39may exacerbate the cycle of of
  • 42:42sedentary behavior in this population.
  • 42:48So in the final part of my presentation,
  • 42:52I would like to make the case for
  • 42:54how integrated care options for
  • 42:56cardiovascular populations and
  • 42:58specialty care are needed to come
  • 43:01to a more value based care delivery.
  • 43:03So, as I highlighted throughout my talk,
  • 43:06atherosclerotic disease is a
  • 43:08generalized process and manifestations
  • 43:11can occur in the coronary,
  • 43:13carotid and lower extremity arteries.
  • 43:15And even though the interest in the
  • 43:18field started in coronary disease
  • 43:21because those manifestations were
  • 43:23probably also more dramatic and and,
  • 43:26and that's where everything started.
  • 43:29I feel like we're just at the beginning of
  • 43:32documenting and understanding the impacts
  • 43:34of other manifestations on people's lives.
  • 43:36I haven't even covered
  • 43:38carotid artery stenosis,
  • 43:39which is another unique set of symptoms
  • 43:44and care interactions that need to
  • 43:48be considered for those populations.
  • 43:52So really it makes sense to.
  • 43:55Start broadening the subspecialty
  • 43:57of cardiac psychology and and
  • 43:59to include vascular populations.
  • 44:02Because it's really a spectrum of disease.
  • 44:05And recently we came together with a
  • 44:08few colleagues here at Yale colleagues,
  • 44:11psychologist and cardiologist were we.
  • 44:16Reflected on the role of what cardiovascular
  • 44:19psychology or health psychology could
  • 44:22contribute to cardiovascular care.
  • 44:25There is a, of course,
  • 44:26a role for intervention,
  • 44:28design,
  • 44:29delivery and testing,
  • 44:30and there's a role to address
  • 44:33psychosocial behavioral factors
  • 44:35to promote lifestyle changes that
  • 44:37we often recommend these patients
  • 44:40to make and the support that they
  • 44:43need to help make these changes.
  • 44:46And the impact on their health outcomes.
  • 44:49Health psychology can contribute
  • 44:50to the assessment and the design
  • 44:53and the analysis and interpretation
  • 44:55of psychosocial risk factors,
  • 44:57both at the patient level,
  • 44:59but also measures at the programmatic level.
  • 45:02As a lot of of the fields in in
  • 45:04in medical specialties and in
  • 45:07behavioral healthcare are moving
  • 45:09into measurement based care.
  • 45:11Where we let patients.
  • 45:17Say what quality of care means and and
  • 45:20and how that is reflected in the scores
  • 45:24on on these domains of assessment.
  • 45:27Treating comorbid mental mental health
  • 45:29disorders in the context of medical
  • 45:32illness and facilitate patient care team
  • 45:35relationships and provide insight and.
  • 45:38Expertise and the role of psychology
  • 45:41for physiological interactions that take
  • 45:44place within cardiovascular diseases.
  • 45:46And understanding how it affects the
  • 45:49patients experience and in the last
  • 45:51decade a lot of the treatments for
  • 45:54coronary and cardiovascular disease
  • 45:56in general has gotten increasingly
  • 45:59more technical and with a lot of
  • 46:02technological innovations taking place.
  • 46:03So it's also important to consider what
  • 46:06treatment options are available and
  • 46:08how that impacts the disease process
  • 46:10and the role of psychosocial factors.
  • 46:13And so there too is a role for cardiac.
  • 46:16Would carry a vascular sychology.
  • 46:20So for integrated PED care it is
  • 46:23not only what are the patient wants
  • 46:25stents or or what are surgical
  • 46:28bypass is the right way to go,
  • 46:30or supervised exercise is
  • 46:31something that people might want
  • 46:33to try and the medications to
  • 46:36lower their cardiovascular risk.
  • 46:38But it is also do people have the
  • 46:41support and the capacity to navigate all
  • 46:45of these disease experiences and the
  • 46:47interaction with their treatment and.
  • 46:49Is their care being addressed
  • 46:52from a whole person perspective
  • 46:54and or psychosocial factors also
  • 46:57considered for the disease management?
  • 47:01So increasingly our teams become
  • 47:04multidisciplinary and models of
  • 47:06Co treatment and cross training
  • 47:08actually make sense if we want
  • 47:11to meet the patient's needs.
  • 47:13And as specialties move in and out
  • 47:16the circle depending on on the
  • 47:18different needs and we feel that.
  • 47:20There is definitely a place also
  • 47:22for health psychology to help
  • 47:25support the specialty care of
  • 47:27these populations as they manage
  • 47:29their cardiovascular condition.
  • 47:34Many of of the goals for managing a
  • 47:36depression or managing stress and managing
  • 47:39peripheral artery disease as discussed,
  • 47:42overlap, and so increasingly an
  • 47:45interdisciplinary team based approach
  • 47:47makes sense to to realize more
  • 47:50successful outcomes in this population.
  • 47:56Collaborative work and care has been
  • 47:59shown to be effective for medical
  • 48:02populations such as diabetes.
  • 48:04Oftentimes, these models were offered
  • 48:06offered in the primary care setting,
  • 48:09and so there is a model for success
  • 48:12that has been demonstrated.
  • 48:14But with the increasingly complex
  • 48:17populations and the intensity of
  • 48:19care that people undergo and complex
  • 48:23interactions with their treatments.
  • 48:25There's a case to make to offer behavioral
  • 48:27health care within the specialty setting,
  • 48:30as it also is perhaps desired from
  • 48:33the patient's perspective and from a
  • 48:36referral and care linkage perspective.
  • 48:38Being part of the same treatment
  • 48:40team is is something to strive for.
  • 48:46We're finding ourselves at a new juncture.
  • 48:49Is is what I feel.
  • 48:52We described the post war chronic
  • 48:55disease burden, but we're still
  • 48:57dealing with that disease burden.
  • 48:59And as you look at the
  • 49:02global burden of disease,
  • 49:04ischemic heart disease tops this list
  • 49:08in both populations 50 + 75 years
  • 49:11and plus or populations age rapidly.
  • 49:14And the demands on our health services
  • 49:17and healthcare systems continue to
  • 49:19increase and so this is something really.
  • 49:22Policy makers and healthcare
  • 49:25administrators need to integrate
  • 49:28in their policy and and the way we
  • 49:32deliver and design care for patients
  • 49:34and how that care is value based and
  • 49:37and it is a good return on investment.
  • 49:40So there's still an enormous wave of of
  • 49:42new challenges for the sustainability of
  • 49:45our healthcare systems that is coming.
  • 49:47Towards us.
  • 49:50So we found ourselves at a such a
  • 49:52junction before as I explained in
  • 49:54the beginning of my presentation,
  • 49:56but today's reality adds a little
  • 49:58bit more complexities into the mix,
  • 50:00so I gains in prevention for
  • 50:04cardiovascular disease.
  • 50:05Seem to need to be reinvigorated.
  • 50:07Given that younger populations present
  • 50:09earlier with much more aggressive
  • 50:12disease due to lifestyle factors.
  • 50:14Cost are really unsustainable.
  • 50:17There's highly technological care
  • 50:19being incentivized over basic high
  • 50:22value care and the people who have
  • 50:24access to that highly technological
  • 50:27care versus those who don't.
  • 50:30Those disparities continue to increase,
  • 50:33and there's an enormous burden
  • 50:36towards vulnerable populations who
  • 50:38even have difficulties accessing
  • 50:40care and are being diagnosed early.
  • 50:43And so it does show up late in the
  • 50:46disease process with more complex disease,
  • 50:49and we see decreasing life expectancy
  • 50:53in younger generations because of that.
  • 50:56And and then we face the post
  • 50:58pandemic and and global challenges,
  • 51:01which really has increased the mental
  • 51:04health burden overall and strain
  • 51:07communities that are suffering.
  • 51:09So health psychology can yet again
  • 51:12provide an answer to these complexities
  • 51:15and how to deal with this reality
  • 51:17and contribute to more value based
  • 51:20care models that can address medical
  • 51:23populations from a whole person.
  • 51:27Perspective and offer our expertise in
  • 51:30in the chronic disease trajectories.
  • 51:36I would like to thank all of the
  • 51:40faculty collaborators here at
  • 51:42Yale and outside and and globally.
  • 51:44Also, who have contributed to
  • 51:46this work and the people in our
  • 51:49research team and here at Yale,
  • 51:51but also at the America Heart Institute.
  • 51:54In Kansas City and the team in in Tillburg,
  • 51:58and of course all the patients
  • 52:01that have contributed to this
  • 52:03data of of this body of work.
  • 52:06And I want to thank you for
  • 52:08listening to my talk and having me
  • 52:10in this grand Round series and also
  • 52:12would like to encourage people to
  • 52:14join our upcoming health Ecology
  • 52:17Virtual Forum happening May 20.
  • 52:20Where the growth and contributions of
  • 52:22health psychology will be further discussed,
  • 52:24and I'd be glad to take any questions
  • 52:26and thank you for listening.
