I’m Dr. Ken Sharlin. Welcome to the Parkinson’s Solutions Summit. I’m very excited today to introduce a special guest, Dr. Joel Kahn, a cardiologist, hailing from the great state of Michigan. Dr. Kahn and I have had an association for several years now through a group of top thought leaders in the health field and it is a really unique pleasure of mine to introduce a doctor who not only is focusing on improving people’s heart from a disease perspective, but also creating heart health from their health perspectives. And so without further ado, Dr. Joel Kahn, welcome to the Parkinson’s Solutions Summit.
Joel Kahn, MD, FACC
Thanks, Dr. Sharlin. Excited to be here.
Kenneth Sharlin, MD
Dr. Kahn, I know that those watching this interview would love to hear about your background in cardiology and how you became passionate about helping people in this way.
Joel Kahn, MD, FACC
Sure. I’m in southeastern Michigan in the Detroit suburbs and grew up here. I had a heart murmur as a young child, and I started to see a pediatric cardiologist, and it never amounted to any serious disease, which is good news. But I spent a lot of time in cardiology clinics as a young child and teenager, and I thought it was all fascinating. So I decided I wanted the same path, but I chose an adult cardiology, not a pediatric cardiology path. I went to the University of Michigan, University in Texas a little few hours from Kansas City, Missouri, and have been practicing since 1990. Originally, the main focus was interventional cardiology, angioplasty, stents for heart attacks, and treating bypass patients. But about a decade ago, I threw that all away. Left the 25 years of crazy life, three in the morning, driving as fast as I could to the emergency room. I wasn’t tired of it, I just got passionate about prevention. I had gone back to gain formal training in nutrition, mind, body, and fitness and supplements. And so that’s all we do now. What I used to do, I try to prevent that, I have the trademark prevent not stent. So I guess my colleagues think that I lost my brain. But there’s literally, unfortunately, an endless pool of people that want to know if they have heart disease, want to know if they can reverse heart disease. And germane to the topic today. I do see people from age 18 to age 97, but a lot of my patients are in the medicare age range and they have both neurologic degenerative disease and cardiac degenerative disease. So I don’t take over the role as their neurologist. I’m not trained in that, but I do have input on who they go see and some therapies I recommend and you know, a good number of them do have Parkinson’s disease.
Kenneth Sharlin, MD
Absolutely. I’m wondering when you kind of took that turn about a decade ago, were you seeing some folks, whether it’s the cath lab and maybe they were going back for their second or third stent and saying, I know I’m just putting kind of I’m saving lives, but I’m putting a band-aid over a problem. And I’d like to, you know, maybe take a different route. What made you start thinking about nutrition and mind, body work, and all that?
Joel Kahn, MD, FACC
Well, that’s another quick personal side story. But I grew up in a home in Detroit where we kept the Jewish dietary laws called kosher. And so even as a kid, I would pause for a moment before something went in my mouth. And if it was a cheeseburger or bacon, I didn’t do it because I was grown and taught to do that. And I honored it and rather enjoyed it, actually. And when I went to college at age 18, the only way to survive in the dormitory was actually a massive salad bar. Everything else was off the menu and I found that great. So I’ve actually been vegan since age 18. You can’t help when you’re in, you know, pre-med and med and all the rest. I started to read some books on the side and, you know, there was no, you know, I’d go to the library and read a bit about nutrition and that sort of started it all. So I was pretty deep into, particularly heart disease, and nutrition. Dr. Ornish, the famous Mr. Nathan Pritikin. I mean, I was aware of all their work from the day my practice began, and I was teaching patients in all aspects. I was sort of like you said, I’ll put your stent in, but you have to read a book or watch an online documentary, once we got the Internet and that just flourished. A point that I found so rewarding and so underserved. There were plenty of stent doctors. I had trained so many of them. There were plenty that were 20 years younger than me that were doing a great job. I figured, you know what? I’m going to go into uncharted territory and talk about prevention and reversal. And there’s plenty of science there, too. There’s just not a lot of practitioners.
Kenneth Sharlin, MD
You touched on Dean Ornish and I think he was one of the early pioneers to show that these types of interventions could really change the direction of heart disease.
Joel Kahn, MD, FACC
Right. He was the first one to take an idea. Their lifestyle focused on a whole food plant-based diet could actually reverse heart disease and apply high tech to it. You know, applied PET scans of the heart and applied digital analysis of heart catheterization and take away all the subjective. People felt better, but, you know, was there also documentation of actually real pathophysiology and improvement? And lo and behold, it worked out and has been validated. And that’s what I teach people.
Kenneth Sharlin, MD
It’s wonderful. You know, I think most people at least intuitively kind of understand the fact that, you know, diet is important to preventing heart disease, to preventing brain disease. They may be perhaps less familiar with the fact that if you focus on nutrition, you can actually reverse the disease that already exists.
Joel Kahn, MD, FACC
Right. And you know, we never have enough data. A typical drug you bring to market. We have had a whole bunch of new cardiology drugs in the last few years and a whole bunch more are coming. But a new drug to market might cost a billion dollars and it might fall flat on its face. That’s the gamble the pharmaceutical company takes. But, you know, we don’t spend a hundred million a year on all nutrition science in the United States, far less than that. So, you know, for a couple of million dollars, we could do a really good six-month study and a lot of important questions. That’s why these pearls of science from Nathan Pritikin and Dean Ornish and Joel Furman and some of the others that have actually done studies, published them. They’re never big enough. There’s never enough of them. But they’re so consistent that we know for sure. Now, we have actually new technology that I can study a patient and track them just like they were in. Dr. Ornish’s study, just by what I do in my clinic now, we have that ability to prove that your plaque is reversing and people are highly motivated to achieve that, because there’s no doubt in fact, there’s an article in our medical literature this week A 1% reversal of plaque reduces the risk of cardiac death by 25%. So imagine you could reverse 5% of their plaque or 10%. They’d live forever. They’d be Methuselah.
Kenneth Sharlin, MD
Wow. Yeah. You know, when I first got interested in this sort of approach to neurology, I learned about the number needed to treat statistics. And I remind folks that, look, you know, there is a time and a place for the medication, but oftentimes we take a statin drug or a blood pressure drug, we sort of automatically assume that it is eliminating our risk. And in fact, it’s a risk reduction, and on an individualized level, folks may be shocked to find out that the likelihood of this drug actually preventing that heart attack or stroke or what have you is shockingly low.
Joel Kahn, MD, FACC
Right. Exactly. In fact, in the cardiology world, if you’ve had a heart attack and you go on a statin, you reduce your risk of a secondary attack by about 40%. But that leaves 60% of the risk that we don’t talk about, and that might be sleep and diet and toxins and dental health and fitness. A lot of it’s genetic, genetics that we haven’t made a dent with. So we’re getting better. But, you know, when we apply the whole, you know, functional medicine approach, we can do more than just pharmaceuticals.
Kenneth Sharlin, MD
I’m just curious, do you still add, you know, on an individualized basis, prescribe medication to your patients?
Joel Kahn, MD, FACC
I do. I do. I mean, I’m a supplement-trained, supplement-friendly guy. There are questions about the quality and the purity and, you know, some supplements have impressive research. Coenzyme Q10 is one of those and that pertains to Parkinson’s patients. Other supplements, including the hot ones out now NAD nicotinamide adenine dinucleotide. Yeah, we don’t have big clinical trials to talk about that are really clinically important. But so I use pharmaceuticals, you know, they generally have to go through some hoops to do some science, particularly any newer drug that has to do exhausting clinical trials. You hope they’re honest and sincere. There’s so much money involved. You have to wonder sometimes about the influence on the actual outcome and the publication. Nonetheless, I do. But if somebody says to me, I want to wait three months and change my lifestyle dramatically and recheck my lab work and let me see if I’m one of those famous people that drops my cholesterol by 100 points in three months, with very rare exceptions. I’ll certainly give them that opportunity to do that. And surprisingly, a lot of people actually do achieve that. So we might be able to avoid medication or certainly use greatly reduced doses.
Kenneth Sharlin, MD
Well, for the folks who are watching the summit, they may be saying, gee whiz, you know, you’re interviewing a cardiologist, but I thought this was the Parkinson’s Solutions Summit. And I absolutely promise there’s some rich information to come and is absolutely connected. But one of the things, the pearls, if you will, that I want folks to get out of this interview is that their experience with their doctor, whether that’s the neurologist or the cardiologist, can be very different than what they are accustomed to. It can include things like nutrition. It can include things like mind-body work and so I was wondering if you could walk us through a little bit of what the experience is like if I come and see you as a cardiologist?
Joel Kahn, MD, FACC
Well, you know, there are people that show up with prepackaged records and they’ve had bypass and stents and heart attacks and some lab work, usually very superficial routine lab work. And of course, I go through all those records and then I got to take, you know, a detailed history about diet and exercise and sleep and relations and work and toxin exposures and dental health and all. But then we’re going to do very extensive lab testing way beyond the average. Usually, we can do that through an insurance program. Most of it’s done on request in very widely available labs. We may need to do some extra imaging. We do a lot of carotid imaging. There’s a concept called vascular age. You are as young as your arteries, said an English physician 400 years ago, Dr. Thomas Sydenham. And there’s a way to do a digital carotid ultrasound, safe and with no radiation and actually learn your vascular age. There are more and more. We are using CT scans in place of heart catheterization. There is some radiation exposure. They may be insurance covered, but some people self-pay. The accuracy of our diagnosis. Do they have heart disease? What kind of heart disease? How extensive has been completely transformed by CT scan imaging of heart arteries called the CT angiogram? We’ll go over that and we’ll make a program of improved nutrition, improved fitness, supplements of missing nutrients, and their blood work. You know pharmaceutical agents, sometimes rearranging their pharmaceutical agents, getting among lower dose statins in combination with some supplements that give them the same cholesterol level with far less medication. And we’ll track them over time and try and actually, like I say, if there is coronary artery disease, patients prove that they’re reversing their plaque like Dr. Ornish showed in a small study. But we can do that with anybody.
Now, a larger group of people come to me and they just want to know if they’re okay. Their brother had a heart attack, their mother had a stroke. And we go back a step and we try to determine if they have atherosclerosis. It’s a horrible disease that kills so many people, sometimes suddenly, sometimes slowly. But there’s a long period when you have no clue that you’re aging inside. Maybe it’s your carotid arteries, your heart arteries, or other vascular arteries. And we work through it to determine where you are. That same concept, vascular age. Are you a 55-year-old and your arteries are like a 40-year-old? That’s a celebration. Are you like many of my patients, 55 years old, and their arteries are like 80 years old then we got work to do. And it’s still potentially reversible to some degree, but we got work to do. And it’s just a very puzzling system why we screen for cancer routinely. Very importantly, we screen for prostate, cervical, breast, colon, and lung cancer. We don’t screen people for heart disease, even though it’s a much bigger burden of disability and death cost in the United States and around the world and it’s so simple. There’s a CT scan called a heart Calcium CT scan that takes about 10 seconds available at almost every hospital in America. No I.V., no injection, no iodine, no allergy, no pain or claustrophobia. A very small exposure to radiation. And in some hospitals that costs $50, some hospitals that costs $99, if you want to know at age 40 plus how you’re doing. You go ask your primary care doctor, “Can I get a heart calcium CT scan. You screened me for cancer. I want to be screened for heart disease.” And you want that to come out with a result that you’re a zero, zero score, which would be wonderful news and really makes you, you’re never bulletproof, but nearly bulletproof for 5 to 7 years. And you do it again. And if you come back over zero, you better start reading some of my blogs and listen to my podcasts, because that’s all I do is work with people. They feel fine. They’re playing pickleball for 2 hours, but I’m telling you, their vascular age, their heart, artery age are way beyond their birth age. And there is this great opportunity to pick them up before they’re in an emergency room and work with every modality we have.
The commonality with Parkinson’s disease is there is a big overlap, partly it’s aging. You know, there are 40-year-olds that have serious heart disease, even 30-year-olds. And I’m talking more than degenerative kind atherosclerosis, cause you can be born with a hole in your heart like I was. And that’s not lifestyle-related, but the majority of hard patients are in the Medicare age range, and so are the majority of Parkinson’s patients. And they share a lot of the same illnesses: high blood pressure, high cholesterol, high blood pressure, poor diet, limited exercise, obesity, and poor nutrition. It’s been shown that the same pathophysiology is inflammation through the body, which is very detrimental to the heart patients and also can involve the brain. Neurologic inflammation, which is some fancy term called oxidative stress or rusting of your tissues, glycation or glucose coating of your tissues occurs in the heart, arteries occur in the brain. So we share so many common abnormal pathophysiology, fancy words there, that there are a lot of heart patients with Parkinson’s disease and a lot of Parkinson’s disease patients that have heart disease. And that’s why I see them. And, you know, I have to cross the line. I never want to be their neurologist, but I do give them three, four, five, and six lifestyle recommendations to consider.
Kenneth Sharlin, MD
Common root cause is really when it comes to understanding why we get sick and what it takes to ultimately turn that around and get better. When I first learned functional medicine and was introduced to the idea of functional biological systems, but just sometimes called systems biology, it really clicked for me because we’re so used to, as you and I are both specialists, to think, “Well, there’s the heart, there’s the brain, you know, there’s the gut, the gastroenterologist or whatever.” And as if everything is practiced in its own separate box, and in fact, in conventional medicine, it is practiced in its own separate box, which causes maybe as many problems for folks as it has the gains that they may get. You know, to think that these are somehow not connected.
Joel Kahn, MD, FACC
Right. And there are, we know, I’ll just go through and, you know, I hope this doesn’t offend you from your perspective, but I do talk to people in my clinic that have Parkinson’s disease about nutrition. I mean, they’re in my clinic because they probably have a cardiac disease. But there is some data. I wrote a book about five years ago called The Plant-Based Solution, and I have a chapter on neurologic disease. I pulled out all the references to eating healthier. In my world, that means whole food plant-based had some impact on neurologic disease. But just recently, a famous resource called the UK Biobank published a paper and predicted that healthy eating is effective at reducing your risk of Parkinson’s disease. And you know the study of over 100,000 participants with dietary histories. And they found in a very large study, you know, there was nobody with Parkinson’s disease at the beginning of the study, and there were about 600 that developed it over the next 12 years that those that ate the healthiest plant diets had the lowest rates of Parkinson’s disease and those that ate the unhealthiest plant diets. They were still plant-based diets, but they might be fried food, processed food, and packaged frozen food. Stuff that doesn’t really qualify as coming from your garden had the highest rates of Parkinson’s disease developed.
So it’s almost the exact same paper you do for heart disease or cancer development. And, you know, it’s what you know and I know we got an association study and you have to then go do the research and say, you know, what was it in the bad food that’s toxic or what’s it and good food that’s therapeutic? But why was there such a significant spread? So, you know, I try to get most people on a largely whole food plant-based diet but I will extend that to people with you know neurological degenerative disorders And maybe Parkinson’s disease is the best study.
There’s little data on Alzheimer’s, too. In fact, to circle back, Dr. Dean Ornish right now, how many years after the lifestyle hard trial, 33 years later because it was published in 1990, is doing a prospective Alzheimer’s study with whole food plant-based diets and the Ornish lifestyle. So there’s been no data to suggest that’s helpful. But he got enough funding that he’s doing. A prospective randomized dietary lifestyle trial will be exciting to see those results. I don’t know about you. Almost everybody in my practice takes coenzyme Q10, a widely available supplement. A lot of my colleagues say, “Why do you use supplements? It’s expensive urine.”
Well, in cardiology, without a doubt, there’s more data for coenzyme Q10, also called CoQ10 is a beneficial supplement than any other supplement in our vitamin shop, and there’s data for congestive heart failure. That’s impressive. There’s data for longevity from Sweden that’s impressive. There’s data for hypertension and arrhythmia but there have been a number of studies of coenzyme Q10 in Parkinson’s disease, and they remain mixed and somewhat inconclusive, certainly very safe. I like the studies because they use crazy high doses of coenzyme Q10 over 1000 milligrams a day. Most people take 100 to 200 milligrams a day, and they certainly have proven the safety of high-dose coenzymes in these studies. But it isn’t a magical cure that works overnight. But it’s you know, it’s something that I do bring up to them that they probably needed for their disease and they may get some benefit. I actually encourage my patients to drink coffee if they don’t have jitteriness or palpitations. There is little data about coffee potentially being Parkinson’s disease preventive. And there’s a statistic out there that a lot of people get more antioxidants from coffee than anything else in their diet because they’re eating so few fruits and vegetables. Obviously, fruits and vegetables are where most of the antioxidants are for oxidative stress but coffee is something that we talk about. One of my colleagues has Cardiology Coffee as a brand in the market. A little bit beyond what I’m doing now. But nonetheless, I am a coffee drinker, a couple of cups in the morning, and of course exercise.
There is some clinical trial data that people that are in good shape and do moderate or vigorous physical exercise have a lower risk of Parkinson’s disease and a whole lot of other diseases. And of course, if they already have well-developed Parkinson’s, they may have some challenges. I don’t know about you, but I’ve got this group of people with Parkinson’s that are doing boxing classes, you know, in their seventies and eighties. And it’s just such a hoot but they love it and it’s non-contact boxing so nobody needs to get too worried. We’re not beating up the elderly people, but there’s just something about their coordination and their balance and they seem to benefit. So and then the last one I bring up with some of my patients, and I know it’s on the edge and not completely proven, but I have several red light panels in my house, red light therapy called photobiomodulation, and they expose your body to a spectrum of red lights. But there are some unique, you know, caps or brain exposure by light. So the one, I know the company and, you know, I would judge them to be pretty harmless. And then I try, and provide for my patients, these are things you can decide. It’s a couple of thousand dollars to get one of these dedicated light devices for the brain. But some of them involve even a little probe up the nose. So you’re really almost directly exposing brain tissue to red light.
Kenneth Sharlin, MD
Right.
Joel Kahn, MD, FACC
So, I mean, these are the kind of things I cross the border, as your neurologist might think. We’re crazy here. When you’re done taking coenzyme Q10 or using a red light or, you know, and all. But again, as much as possible, we want to prevent, you know, disease before we have to treat it. So everybody needs to eat healthy, largely plant-based needs to get an exercise program together and, you know, maintain a proper body weight. There’s probably something there about reducing inflammation and stress.
Kenneth Sharlin, MD
Absolutely. Some of what you’re saying reminds you of the famous line by Michael Pollan about “Eat real food, not too much, mostly plants.” Right. And we see real shifts when folks do that, whether or not they choose to be vegan entirely. But going away from the meat and a little side to the mostly side and at least, you know, a smaller portion of the animal-based protein, it now shifts the numbers and there is data out there for Parkinson’s disease. A lot of folks, if they say, well, you know, kind of breakdown what food is in terms of vitamins and things like that. And they know that there’s, you know, fats, carbohydrates in proteins. Most people know there are vitamins and minerals, but not a lot of people know there’s a whole other class of micronutrients said from the numbers perspective really is a much larger group than any of the other components of food, and that is phytonutrients. And there’s actually been some pretty provocative data on Parkinson’s disease and looking at Flavonoid Polyphenol type intake, and these are basically what we’re talking about is so these active compounds in things like green tea, but also found things like blueberries, strawberries, blackberries, the colors, dark chocolate, by the way, would also count, but ultimately in both prevent were slowing the progression of Parkinson’s disease from a neuroprotective perspective.
Joel Kahn, MD, FACC
Right. Absolutely. And you know, this Polyphenol, Flavonoid in all science, it’s such a mouthful and difficult to keep track of, but, you know, take cacao powder or cocoa. I mean, who wouldn’t like to put a little cocoa in your coffee and make it taste like chocolate coffee? And now we’re learning that both for cardiac disease and neurologic disease, it’s a very good idea. I mean, clearly, you don’t want to put in sugar-sweetened versions. I buy raw, organic cocoa powder and many providers online do that. Little scoop in your coffee and you get yourself a double health drink. So I do that regularly.
Kenneth Sharlin, MD
Super big treat. So we’re hearing that anything that puts you at risk for heart disease puts you at risk for brain disease. And we can do the broad brush stroke kinds of things, diet, exercise, etc. But I’m also hearing that if I visit you in the office, what I’m going to get a very personalized type of approach, I’m not going to get well, you know, and I see this in my office. So I’m curious kind of how you approach it, but I’ll see folks who have what may be in the most generic sense would be high cholesterol, whatever that sort of means. And but they don’t they don’t have any other you know, they don’t have high blood pressure. They don’t have insulin resistance. They have healthy-looking carotids in the coronary arteries. Yes, their cholesterol is high, but maybe their so-called good cholesterol is also high so that their ratio of cholesterol to HDL is good or they have very I don’t know if you want to get into talking about particle size studies or oxidized LDL, but those numbers look good. And oftentimes it seems like there is a knee jerk, well, your cholesterol is high, change your diet or get on a statin. But maybe we don’t need to be so obsessive about that. And think of things a little more on an individualized level as it’s really a problem.
Joel Kahn, MD, FACC
Yeah. And unfortunately, you know, most studies are done and report on a group of 10,000 patients, 5,000 patients, you can derive lessons. Where you really care when you’re in a doctor’s office, you care about your health and your doctor has to apply all the science and boil it down to one patient at a time. And it’s hard work and it takes time and effort. So you presented an example. Your cholesterol is high and the primary care doctor is recommending to go on prescription medicine for life and they’re all good-intentioned but there is a problem there. Way back in around 2007, the cardiology group got together, called The Shape Society, and they challenged that convention to say, you know what, before you get on lifelong prescription cluster line medicine, I’m not talking about people who’ve had a heart attack or bypass or stents I’m talking about. I feel fine. I played pickleball, but my cholesterol was 260. Get a carotid ultrasound, See if you’ve got plaque you don’t know about. You might want to go on a medicine if you do. Get a Heart Calcium CT scan for $75. If you’re a zero, you’re in good shape. If you’re 470, do just a number but a very serious number. You might want to go on a statin. And they propose that there is a lot of pushback. But over the years have been so many studies that say if you do these imaging studies and they come back clean, you really forgo the statins. So as of 2019, to this date, the American Heart Association, the Canadian Heart Association, and others have agreed with this proposal and 15, 20 years ago that we can individualize care, personalize care and, you know, give the people with high cholesterol, but apparently bleeding arteries a good bill of health and encourage fitness and sleep and weight loss and proper plant-based nutrition, maybe use some supplements, but we don’t need to put them on prescription drugs. And that’s a rather radical breakthrough. It’s still practiced by a real minority of primary care and cardiology groups. I mentioned this heart CT scan a couple of times. It’s absolutely puzzling why we have a medical system where we screen for five cancers lung cancer, prostate cancer, cervical cancer, breast cancer, and colon cancer. And number one, there are about 50 other cancers we don’t screen for, although there are new blood tests that allow that. But we don’t screen for heart disease at all. We waited to be in the emergency room to find out absolutely no. And you don’t have a minor case of heart disease when you’re in an emergency room, you’ve got end-stage heart disease. So the CT scan done at age 45 for 50 to $100 serves such a useful screening capacity. If you’re a zero, you come back and do it again in 5 to 7 years. It’s the easiest test. You just lie down, hold your breath, and go home. No needle, no injection. And if you come back for 478, you better find some preventive doc to work with you on. Why? And that’s going to be a lot of blood work, a lot of questions about your diet and lifestyle, and putting together a program to start reversing that problem.
Kenneth Sharlin, MD
Dr. Kahn, I’m wondering if we could define for the listeners the viewers’ metabolic syndrome. This is something that we easily associate with heart disease and stroke, and yet the literature tells us this is a major risk factor for Parkinson’s disease.
Joel Kahn, MD, FACC
Yeah, metabolic syndrome, you know, has had other names in the past, but it’s had this name for a good 20 years. There was something called Syndrome X, and I think it was Raven’s syndrome after a researcher. But it’s it’s a constellation of findings that often go together high triglycerides, high blood sugar, high blood pressure, waistline abnormalities, and low HDL. Five things. You can have three of them, four of them, five of them that meet the criteria. It predicted the future development of diabetes, the future development of heart disease, and the future development of other degenerative diseases like certain brain diseases. We’ve had that data for a long time. There are, you know, billing codes for metabolic syndrome, so you can enter it in your chart. Note if you’re perceptive and noticing the pattern, it’s reversible. Might take weight loss, might take exercise, might take diet changes, might take supplements, might take prescription drugs. Just in the past couple of weeks, there was a very large study that just reemphasized those who met the criteria for metabolic syndrome had a much higher risk of disease in general. It’s just, you know, bad biochemistry going on insulin, even though it doesn’t include the blood test for inflammation and the blood tests or this oxidative stress, those are out there. But, the definition of the metabolic syndrome preceded some of that work. But, you know, birds of a feather go together. The metabolic syndrome is about insulin resistance, which isn’t good for the heart and it’s not good for the brain, not good for cancer. So it’s it’s a useful term to say, yes, ma’am or sir, you’re just worn out. Your car needs an overhaul. You are not firing your pistons in a good synchronized manner.
Kenneth Sharlin, MD
And so often when I see folks and there’s maybe that hemoglobin A1C and maybe it’s like 5.9, I say, well, 5.9 is, yeah, my doctor, I’m not diabetic yet, not diabetic yet. Right? And as if we’re sort of waiting till we become diabetic or has anyone actually looked at that fasting insulin level and said, look, you know, this is really a gateway disease. Yeah.
Joel Kahn, MD, FACC
Right now pre-diabetes is still a disease. And it’s you know, it may be pre-diabetes, but it doesn’t mean it’s pre-heart disease, pre-cancer, pre-brain degenerative disease. And also, you know, if your doctor tells you your hemoglobin is over 5.6, you want to ask the question, you know, can I reverse that? Can I drop 20 pounds? Change my diet, hit the gym, and take some supplements as some people get on prescription drugs like metformin that can lower that number. And over the long haul, you’re going to be very grateful if you identify that. Although the problem is that I don’t know if 10% of primary care docs draw a hemoglobin A-1 C, you know, of course, endocrinologists do. If you’re there for diabetes, but that’s already an advanced disease. But this term, pre-diabetes should me should they have some scarier name for it, you know, or premature death syndrome or something.
Kenneth Sharlin, MD
That would be.
Joel Kahn, MD, FACC
That would catch more attention. Yeah.

And trying them for a loop even further is of the percentage that checks the hemoglobin A1C a far smaller percentage checks an insulin level. And that tells people so much more because, you know, your sugar’s really only going to be as high as your insulin level is and insulin could arise. You’ll become insulin resistant by adapting mechanisms that the cell is trying to protect itself. And then ultimately, when thing when the system is just completely overwhelmed, that’s when the blood sugar really starts to go off. But I tell people that when, you know, when you give yourself insulin as a diabetic and I’m talking about type two diabetics who have gone that far and beyond the pills and all that, you know, you’re not peeing out sugar, you’re just shoving it into the cell. I’m sorry, I’m not, I did not say that right. You’re not peeing out the sugar. You’re either, you know, shoving the sugar into the cell, potentially making the problem even worse because insulin resistance is sort of a good thing in a way, in the sense that it’s your body’s way of protecting yourself. It’s not inherently damaged, it’s trying to prevent the damage from happening.
Joel Kahn, MD, FACC
Right. Right. Well said.
Kenneth Sharlin, MD
Well, we have a few more minutes left and there was a topic I just want to spend a couple of minutes on. I hope you go there with me. And that’s one that’s very important to Parkinson’s patients and that’s autonomic dysfunction and often having that drop in their blood pressure when they stand up, some of the men having erectile dysfunction and cardiologists, neurologists, both manage this sort of problem.
Joel Kahn, MD, FACC
Yeah, I actually had the pleasure in medical school and residency and working with a very esteemed endocrinologist whose research project was on autonomic apathy in diabetics, and published many papers with him and the 1980s. It’s a long time ago but you know, those lessons have stood in my career well. As we spoke for a minute before we came online, we were scanning people in Ann Arbor in the 1980s with what’s called nuclear medicine and injection. And then you lie on a table under a scanner. We have a unique agent that nobody’s ever heard of called MIBG that could scan for your autonomic nervous system in your heart, we identified many diabetics and abnormal sympathetic nervous systems and were at risk for dying suddenly, which was known. But we didn’t know that it impacted the heart that way. It turns out that imaging agent is still around and used in certain centers and has been studied in people with Parkinson’s disease and has been shown to identify that the nerves supply to the heart can be very abnormal in Parkinson’s disease, the sympathetic adrenergic adrenalin system can be very depleted.
So that’s not the only reason but you stand up in the normal response, which is mainly your sympathetic nervous system, to maintain your blood pressure so you don’t feel lightheaded, and dizzy and the risk of blacking out is weaker than it should be. And that’s called autonomic dysfunction or static hypotension or something. I think you guys call in your field the Scheidegger syndrome as very challenging. That’s why we want to prevent Parkinson’s disease, if we can, before treating it, because this is a difficult one. We, you know, get people volume-replete ID to carry around a water bottle, but a few salt tablets or mineral solutions in there like a lot of people do. Be careful getting up. Maybe some exercise can improve the tone and, you know, a rebounder or squats or something that improves venous blood flow, support hose to improve venous blood flow back to the heart. There are there’s really no vitamins for this situation, but there are some prescription drugs, not particularly nice prescription drugs that have you hold on to more salt and water. So you stand up and you’re less likely to experience this. But it’s it can be extremely disabling in the Parkinson’s group. I can be their number one symptom. And it’s it’s again an ounce of prevention where the pound of care. So you don’t want to get this syndrome don’t get Parkinson’s disease. One answer is not to get old. That’s not a fun one. One is just, you know, eat this healthy, plant-based diet that this recent study said. Get your exercise on most days of the week. Try and maintain a flat belly and a good ideal body weight. All of these things are tough. Get good sleep and get jacked, get checked, get checked.

Well, well, you’ve heard it from one of our nation’s leading heart doctors, Dr. Joel Kahn. He’s been a guest at the Parkinson’s Solutions Summit, talking matters of the heart and the brain and how much they overlap. If you’re taking care of your heart, you’re taking care of your brain. And if you’re taking care of your brain, by golly, you’re going to be taking care of your heart. And so it’s so important to think of these as really brethren, you know, as we are. Dr. Kahn, it’s been a pleasure chatting with you. If somebody wanted to reach out to you, they’re concerned about their heart health. They want to have a calcium scan under your watchful eyes. How do they how do they reach you? How do they find you?
Joel Kahn, MD, FACC
It’s kind of you. I’m licensed in about half the states. In the United States, I do office and telemedicine and the central website drjoelkahn.com. And you know, we’re in suburban Detroit. A lot of people come to visit me here, and otherwise, the option is to set up something by telemedicine. But yeah, we work hard every day, but we love what we do. It’s a small but mighty clinic.
Kenneth Sharlin, MD
Well, Dr. Joel Kahn, thank you so much for being part of this Parkinson’s Solutions Summit today. Yeah. And I certainly look forward to having some more conversations with you in the future.
Joel Kahn, MD, FACC
Thank you for all the work you do. Absolutely.
