Ep. 21: The Six Domains of Optimal Health — with Dr. Alan Rozanski, Cardiologist

What if the secret to heart health isn’t only in your arteries, but in your mindset, your relationships, and your sense of purpose? In this special conversation, Dr. Regina Druz sits down with one of her own mentors — Dr. Alan Rozanski, a pioneer of nuclear cardiology who went on to help create the field of behavioral cardiology. He shares the astonishing moment that changed his career: watching a patient’s heart visibly falter not on a treadmill, but simply while talking about the stress of losing his job. From there, Dr. Rozanski traces decades of research linking chronic stress, depression, and isolation to heart disease — and, just as importantly, the positive factors (optimism, gratitude, purpose) that protect it. He introduces his six domains of optimal health and a refreshingly simple ‘vital sign’ for well-being: your sense of vitality.

[00:00] Introduction & Meet Dr. Alan Rozanski

Dr. Regina Druz (00:02): Welcome to Own Your Heart Health. I’m Dr. Regina Druz, your holistic cardiologist. This week we’ll dive into common heart health concerns, uncovering root causes and unpacking scientific discoveries and controversies. The information provided does not constitute medical advice. Please contact your healthcare practitioner before making any changes that may impact your health.

Dr. Regina Druz (00:40): Welcome, everybody. I am absolutely delighted today to be with a mentor and a giant in the field of cardiology — someone whose articles I read as a young fellow coming into nuclear cardiology, just trying to comprehend the field at his level. I’m with Dr. Alan Rozanski, a professor of medicine and a pioneer of nuclear cardiology who, as I recently learned, is now making an immense contribution to integrative cardiology through a program he developed. Welcome, Alan.

Dr. Alan Rozanski (01:17): Thank you, it’s a pleasure to be here.

[01:30] From Aspiring Psychiatrist to Nuclear Cardiology Pioneer

Dr. Regina Druz (01:30): People constantly ask me how I became an integrative cardiologist, so I’ll ask you the same: how did you become one?

Dr. Alan Rozanski (01:37): It wasn’t recent — you might say it happened by accident. I started medical school at Tufts wanting to be a psychiatrist, but on my cardiology rotation I fell in love with caring for cardiac patients — taking the history of chest pain felt interactive and meaningful. In fellowship, the part I loved most was putting people on a treadmill, watching how they did in real time, so nuclear cardiology was a natural next step. Mount Sinai didn’t yet have that training, so I arranged a six-month elective at Cedars-Sinai in Los Angeles, where I was assigned a research project under Dr. Daniel Berman. It became a very impactful study, and it led to a faculty position at Cedars-Sinai.

Dr. Regina Druz (02:55): Let’s pause there — because for those who don’t know, that’s the study that lifted nuclear cardiology out of the dark rooms where radiologists sat reading heart scans into a full-fledged cardiology subspecialty. It was the first subspecialty I personally embraced. To explain for listeners: nuclear cardiology uses radioisotopes to study blood flow and wall motion of the heart during stress. Its big contribution was establishing cardiac imaging as a functional test — seeing how the heart actually performs under a workload — which to this day sets it apart from anatomic tests like calcium scoring or CT angiography that image the heart at rest.

[04:00] A Career Crossroads

Dr. Alan Rozanski (04:00): So I’m doing this research, and by year two or three I’m getting bored — I’m a people person, and sitting reading scans all day just wasn’t me. I was getting less and less happy and didn’t know what to do. Driving home in Los Angeles, I used to listen to a talk-radio show by Dr. David Viscott, a psychiatrist taking callers’ questions, and I was fascinated. It occurred to me — maybe I could actually go see him. So I looked him up, made an appointment, and told him I wasn’t sure about my career choice; I regretted not going into psychiatry. He said, ‘Forget about it — you’re already an established cardiologist. Just call the head of psychiatry at UCLA and offer to be their cardiologist.’ I thought it was the most ridiculous thing I’d ever heard. And Monday morning, that’s exactly what I did.

[07:00] The Cardiologist for the Psychiatry Department

Dr. Alan Rozanski (07:00): I called the chief of psychiatry, explained myself, and didn’t expect a reply. Three days later the secretary called back: there’s a doctor you should meet, Dr. Herb Weiner. I had no idea he was a towering figure in psychosomatic medicine. He told me about a new MacArthur Foundation initiative — a network studying the determinants of health and health-damaging behaviors — and that they’d fund a sabbatical fellowship for a multidisciplinary research proposal.

Dr. Regina Druz (07:55): What year was that? It sounds remarkably forward-thinking.

Dr. Alan Rozanski (07:58): Around 1984. ‘Multidisciplinary’ and ‘neurobehavioral research’ were not in the common physician vocabulary then — they had real foresight. So I went home and thought about it. At that time there was a wave of work on ‘silent ischemia,’ and we could now put ambulatory ECG monitors on people and watch them during daily life.

[09:30] The “Aha” Moment: When Talking About Stress Stopped the Heart

Dr. Regina Druz (09:00): Let me define silent ischemia for listeners: it’s when the heart muscle is temporarily starved of blood supply, but the person feels nothing — no symptoms at all. Nuclear cardiology and other imaging can detect it, and we know it’s more common in certain groups, like older and female patients.

Dr. Alan Rozanski (09:38): Exactly. People were having silent ischemic episodes while driving or doing ordinary activities, at lower heart rates than we’d need to induce the same ischemia on a treadmill. I thought — maybe we can model this in the lab. Instead of exercising patients, why not give them mental tasks to induce stress? Dr. Weiner introduced me to psychologists, and we built a battery: a cognitive stressor like serial-7 subtractions, and simply asking patients to speak about the stress in their lives. The second patient was a man of about 60 about to lose his job. As he talked about that stress, his ECG changed and — lo and behold — about half his heart stopped moving, just from talking. We studied about 40 patients, and roughly half showed these abnormalities.

Dr. Alan Rozanski (11:50): Just from speaking about the stress in their life — no task at all. I should add, these were patients with significant heart disease; we also studied healthy people, and none of this happened in them, so no one should get overly alarmed. But for me it was a stunning aha moment I couldn’t walk away from.

[12:00] Chronic Stress, Depression & the Body

Dr. Alan Rozanski (12:14): With the two-year MacArthur sabbatical, I found myself at Duke, Bethesda, and Yale, meeting people in this budding field of behavioral cardiology. I saw Dr. Jay Kaplan’s monkey model where stressed animals, on controlled diets, developed more atherosclerosis; Bruce McEwen’s work at Rockefeller showing chronic stress enlarges the amygdala and shrinks the hippocampus and prefrontal cortex. I began asking a precise question: what is objectively healthy versus unhealthy? Healthy things protect against disease, support physiology, and promote lifespan; unhealthy things do the opposite.

Dr. Regina Druz (14:44): In functional medicine we talk about hormesis — a hormetic threshold. A certain amount of stress conditions the system and builds resilience, but once it overwhelms that threshold, it turns detrimental. And what I see now in patients, in myself, and in my family is less of the one-time acute stress and more of the chronic, repetitive stress that, over time, erodes our resilience and undermines our foundation.

Dr. Alan Rozanski (16:09): That’s the duality of stress. Chronic stress you feel you can’t control, that seems meaningless, that causes emotional distress — that’s the toxic, damaging kind. But the flip side is the stress we pursue in meaningful goals, where we struggle and overcome and grow; that builds optimism, resilience, self-esteem, even pleasure. Then, in the mid-to-late 1980s, interest grew in depression and heart disease. Today everyone accepts depression as a risk factor; back then it was met with deep skepticism. We found that in poorly treated depression, the body’s major systems go haywire — high cortisol, a revved-up sympathetic nervous system, visceral fat, inflammation in the arterial lining, the amygdala enlarging — with a much higher risk of heart disease.

Dr. Regina Druz (17:13): Hi everyone, it’s Dr. Regina here. I know there are contradictory opinions about nutrition for heart health and longevity — the discussion gets heated and confusing. Some push low-fat, low-cholesterol; others are fans of a ketogenic diet; and there are many voices urging vegan or vegetarian eating. To cut through the clutter, my team and I created Holistic Heart University: on-demand courses, nutrition and lifestyle resources, and supplement guidance to make healthy choices for your heart easier to understand. I’m especially proud of our open office hours and the Q&A feature where you can put us in the hot seat.

[19:00] The 1999 Circulation Paper & Norman Cousins

Dr. Alan Rozanski (19:12): Around then, the editor of Circulation asked me to write a review on stress and heart disease — a chance to influence the field through the leading cardiology journal. I spent about five months reviewing every relevant article and we emphasized depression, anxiety, chronic stress, and — newer at the time — social isolation and lack of social support. We submitted it with nearly 300 references; the editors said they didn’t accept articles with that many and wanted two-thirds cut. I argued that, given how much skepticism still surrounded these factors, the references were the point. They agreed, the paper was published, and we were off to the races. (This was the landmark review, published in 1999.)

Dr. Regina Druz (22:45): And the stigma — in the 1980s and ’90s, mental and emotional health were barely discussed in cardiology.

Dr. Alan Rozanski (23:00): Years earlier, in a UCLA bookstore, I’d picked up a bright red book, The Healing Heart, by Norman Cousins — the famous philanthropist who’d written Anatomy of an Illness. This new book was about recovering from a heart attack using positive emotions and humor. He was at UCLA, so I called and asked to meet him, and he had a profound influence on me: he was all about how positive health protects against disease. It made me realize I’d only been studying the negative factors that cause disease, not the positive side that prevents it.

[24:00] The Power of Positive: Optimism & the Life Orientation Test

Dr. Regina Druz (24:20): Right — we know certain things are bad, so what good things can we bring in to shift the balance in our favor?

Dr. Alan Rozanski (24:31): Exactly, and a literature on positive emotions and health was emerging — like the Nun Study, where nuns whose diaries had more positive content lived longer, and the positive-psychology movement of Martin Seligman and others. I began focusing on optimism versus pessimism. I’m more of a synthesizer than the originator here, but the first important studies arrived around 2000, and over the next decade about a dozen accumulated. We published a meta-analysis several years ago showing that people with a more positive outlook live longer and have less heart disease.

Dr. Regina Druz (25:51): How is a positive outlook actually measured?

Dr. Alan Rozanski (26:01): Different ways over time. Seligman looked at explanatory style — whether people frame a setback as pervasive or limited, whether they self-blame. But the standard became the Life Orientation Test, a brief six-item questionnaire (with a few filler items) measuring optimism about the future. It’s been used in younger and older people, in the U.S. and abroad, and tied not just to cardiac outcomes but to a lower risk of dementia. The results are astonishingly uniform — it’s a remarkably predictive scale.

[28:00] How to Build Optimism: Start With Gratitude

Dr. Alan Rozanski (28:05): When we published the optimism analysis, the press kept asking: how do people become optimistic? The truth is that optimism is an indicator that other things in your life are working — just trying to ‘be optimistic’ is too high a reach. Optimistic people have a sense that they can handle what comes their way. So if you want to build big optimism, first build small optimism — in micro-steps, just like starting to exercise. I tell people not to start with optimism; start with gratitude, because negative mindsets carry an emotional overlay you’d also have to address, whereas gratitude meets little resistance. It isn’t easy — humans are built to take things for granted — but it’s the most accessible entry point.

Dr. Regina Druz (31:22): I did an episode called My Top 5 for 2025 about showing grace to yourself, and I talked a lot about gratitude. I’m fortunate to work from home, and in my office I have a little corner with photos of my family and cards my kids gave me when they were young. Every day when I walk in, I stop there for my ‘gratitude minute.’ It resets me, so whatever comes that day, I’m in a different mindset. I also tell patients to take ‘micro-breaks’ — a minute or two to reset — and there’s a concept I love called joy conditioning: reliving or reminiscing about positive experiences in moments when you’re not feeling great, to reset into a happier mode.

Dr. Alan Rozanski (33:30): That’s fantastic — and I listened to your 2025 episode. Your gratitude corner is exactly it: you created a cue for gratitude, and people coming up with their own cues is really important. Don’t underestimate just taking a couple of minutes a day. It isn’t easy, so you have to work at it until it becomes habitual — and if it doesn’t take at first, you get back on the bike. Over time it can make a profound difference, and that’s how you build the positive mindset that leads to optimism.

[36:00] The Mind-Heart Connection in the Clinic

Dr. Regina Druz (34:50): I came from a family and culture where the ‘touchy-feely’ thing wasn’t a thing — you kept a strong front. So coming into a field as technical and quantified as cardiology, I never thought about the role of emotion — until, as a fellow in the late 1990s, my co-fellow and I were rounding in the coronary care unit with patients whose heart rates were racing after heart attacks. He said, ‘Let’s give them morphine.’ I asked why, to slow a heart rate — and he said, once you take the edge off and they relax, you’ll see the heart rate come down. And it did. That was a profound early lesson.

Dr. Regina Druz (36:00): Years later I came across an article from the Harvard group — Dr. Peter Libby and colleagues — on the brain-heart connection. In patients after a heart attack or a stressful procedure, the stress itself triggered immune activation, recruiting cells like macrophages and leukocytes to the site of coronary plaque to participate in plaque remodeling — the so-called echo phenomenon, where our very thoughts can initiate the biology of atherosclerosis. That article profoundly changed me; I stopped underestimating the mind-heart connection.

Dr. Regina Druz (38:33): Hi everyone, it’s Dr. Regina here. Many of my colleagues and I are seeing patients arrive with self-ordered blood tests. When this trend started, I thought it would help — who doesn’t want more access to their health data? But too often self-ordered labs lead to more confusion and frustration: patients come in with a pile of results and are no better off. That’s why we created HeartWell Toolkits — a curated collection of at-home blood and genetic markers focused on heart and brain health that gives you the data you need to make informed, actionable decisions.

[39:30] The Six Domains & Vitality as Your “Vital Sign”

Dr. Alan Rozanski (39:30): So tell us about the six domains of optimal health — and when did you launch them? It was a progression. By the 1999 article we’d covered the emotional domain (depression), the social domain, and stress; physical health was a given. What was missing was the mental piece, filled in by optimism and pessimism — and there’s data that more forgiving people, and gratitude, benefit cardiac physiology. The last addition was purposeful living. The first studies linking a sense of purpose to longevity came out only 10 to 12 years ago, and our meta-analysis found, just like with optimism, that people with a strong sense of purpose live longer, have less heart disease, and even a lower risk of dementia — work associated with Patricia Boyle. So the six domains are physical health, mental vitality, emotional mastery, social connectivity, stress management, and purposeful living — each evidence-based, each running from positive to negative, and all interrelated.

Dr. Alan Rozanski (42:00): They’re connected in one profound way: when any domain is functioning well, it produces a greater sense of vitality — feeling energetic, which is pleasurable and activating. And because we feel more vital, we want to do more, which deepens our sense of purpose. It’s all one loop.

Dr. Alan Rozanski (44:32): Is it measurable — can you tell a person where to focus? There’s a flip side to sophisticated measurement: is there a simple way? And there is. We have vital signs — heart rate, blood pressure. For health, I say the vital sign is your sense of vitality. If you feel energetic, wonderful. If you feel less than energetic — not necessarily fatigued, just not vital — then something is off in one of the six domains.

Dr. Regina Druz (46:00): I’d call that ‘zest for life’ — we’ve all met people who aren’t in great physical health yet have tremendous zest, and others who look perfect on the outside but have lost it. I find the people with real mental vitality are curious and open-minded, still learning and seeking new experiences in their eighties.

Dr. Alan Rozanski (46:41): 100%. An anecdote: someone close to me called after a cath found a moderately severe lesion, asking whether to have an angioplasty. I wasn’t convinced he needed it, so we talked. On a standard review of systems he denied tiredness or fatigue — but when I asked, on a scale of one to ten, how energetic he felt compared to his best, he said three. He wasn’t ‘tired,’ but he was dealing with enormous non-health stress. If I’d only asked about fatigue, I’d have missed it. It’s like screening for depression: someone can score zero — not depressed — yet still not be happy. You have to look at the whole spectrum, not just one end.

[50:00] Where to Start: Small Steps & Movement + Closing

Dr. Alan Rozanski (50:34): These domains are all entry points toward more positive living — you’re either in a positive loop or a negative one. The empowering message is that one step in any domain lifts the others. The biggest mistake is underestimating small steps. With accelerometer data from the last 10 to 15 years, we now know any amount of physical activity counts — even five minutes. Tell a sedentary patient to do 30 minutes five times a week and they won’t take it seriously; but tell them that going from sedentary to about 10 minutes of intentional walking cuts mortality risk by roughly 20%, and that’s powerful, credible data.

Dr. Regina Druz (52:07): That data is very strong — I believe it’s from the UK Biobank. I talk to patients about ‘exercise snacks’ — sometimes I just film myself walking the dog, and that’s a snack for the day. So, Alan, in closing: with six domains to choose from, where should someone start?

Dr. Alan Rozanski (53:19): Any of them is a great starting point, but I start by getting people moving physically — give me five or ten minutes a day. Depression, in a way, is a state of lack of motion, and exercise has been shown to be as potent as an antidepressant in studies like James Blumenthal’s. So I get people moving more and take it from there.

Dr. Regina Druz (54:30): I agree entirely — and we could do a whole episode on what’s changing in exercise science, from exercise snacks to the power of resistance training across the lifespan. Where can listeners find the six domains of optimal health?

Dr. Alan Rozanski (55:21): I have a website that’s growing — for decades I was in the academic space reaching physicians and training fellows, but now I want to reach the public. It’s alanrozanski.com, and I’m on LinkedIn as well.

Dr. Regina Druz (55:46): Wonderful. We’ll link to Dr. Rozanski’s website and to an optimism assessment so listeners can explore the six domains and score themselves. Alan, this has been fantastic — I learned a ton, and I’m delighted to have had you on.

Frequently Asked Questions

What are the six domains of optimal health?

They are Dr. Rozanski’s evidence-based framework for well-being: physical health, mental vitality, emotional mastery, social connectivity, stress management, and purposeful living. Each domain runs along a continuum from positive (health-promoting) to negative (disease-promoting), and — crucially — they’re all interrelated. When any one domain is functioning well, it tends to increase your overall sense of vitality, which makes you want to do more and deepens your sense of purpose, creating a positive loop. The practical, empowering implication is that you don’t have to fix everything at once: improving in a single domain (even a little) lifts your capacity across the other five. This is educational information, not individualized medical advice; you can explore the framework further at Dr. Rozanski’s website.

Can stress and emotions really cause heart disease?

The evidence is substantial, and Dr. Rozanski helped build it. His early lab work showed that asking heart patients simply to talk about a stressful situation could trigger objective abnormalities — in one striking case, about half of a patient’s heart briefly stopped moving while he discussed losing his job (notably, this did not occur in healthy people). Decades of research tie chronic, uncontrollable stress, poorly treated depression, and social isolation to higher cardiovascular risk, via high cortisol, a revved-up sympathetic nervous system, visceral fat, and arterial inflammation. Dr. Druz adds the ‘echo phenomenon,’ in which stress can trigger immune activation that contributes to coronary plaque remodeling — the biology of atherosclerosis influenced by the mind. The encouraging flip side is that positive factors (optimism, gratitude, purpose) appear protective. This is general education; discuss your own risks with your clinician.

Is optimism something you can build — and how?

Yes, but not by simply trying to ‘be optimistic,’ which Dr. Rozanski says is too high a reach. Optimism is really an indicator that other things in your life are working — optimistic people have a sense that they can handle what comes their way. So he advises building ‘small optimism’ first, in micro-steps, much like starting to exercise. His recommended entry point is gratitude, because negative mindsets carry an emotional overlay you’d also have to untangle, whereas gratitude meets little resistance. Practical tools from the conversation include creating a personal ‘cue’ for gratitude (Dr. Druz’s family-photo ‘gratitude corner’), taking brief daily ‘micro-breaks,’ and ‘joy conditioning’ — reliving positive memories when you’re feeling low. Consistency matters: it takes repetition to become habitual, and it’s normal to need to restart. This is educational, not a clinical prescription.

What’s a simple “vital sign” for overall health?

Dr. Rozanski’s answer is your sense of vitality — how energetic you feel. Just as we track heart rate and blood pressure, he suggests vitality as a vital sign for well-being: if you feel energetic, that’s a good sign; if you feel less than energetic (not necessarily fatigued, just lacking zest), something may be off in one of the six domains. He illustrates with a patient who denied feeling ‘tired’ on a standard review of systems but rated his energy a three out of ten — revealing significant non-health stress that would otherwise have been missed. Dr. Druz frames this as ‘zest for life,’ often paired with curiosity and openness even into old age. The takeaway: pay attention to your vitality as a meaningful signal, and use it to notice which domain may need attention. This is general insight, not a diagnostic tool.
