Allan Sniderman is a highly acclaimed Professor of Cardiology and Medicine at McGill University and a foremost expert in cardiovascular disease (CVD). In this episode, Allan explains the many risk factors used to predict atherosclerosis, including triglycerides, cholesterol, and lipoproteins, and he makes the case for apoB as a superior metric that is currently being underutilized. Allan expresses his frustration with the current scientific climate and its emphasis on consensus and unanimity over encouraging multiple viewpoints, thus holding back the advancement of metrics like apoB for assessing CVD risk, treatment, and prevention strategies. Finally, Allan illuminates his research that led to his 30-year causal model of risk and explains the potentially life-saving advantages of early intervention for the prevention of future disease.
We discuss:
00:00:00 - Intro
00:00:10 - Problems with the current 10-year risk assessment of cardiovascular disease (CVD) and the implications for prevention
00:14:32 - A primer on cholesterol, apoB, and plasma lipoproteins
00:22:07 - Pathophysiology of CVD and the impact of particle cholesterol concentration vs. number of particles
00:28:45 - Limitations of standard blood panels
00:33:10 - Remnant type III hyperlipoproteinemia-high cholesterol, low Apo B, high triglyceride
00:39:26 - Using apoB to estimate risk of CVD
00:42:57 - How Mendelian randomization is bolstering the case for ApoB as the superior metric for risk prediction
00:53:47 - Hypertension and CVD risk
01:05:49 - Factors influencing the decision to begin preventative intervention for CVD
01:11:37 - Using the coronary artery calcium (CAC) score as a predictive tool
01:23:27 - The challenge of motivating individuals to take early interventions
01:26:30 - How medical advancement is hindered by the lack of critical thinking once a “consensus” is reached
01:33:24 - PSK9 inhibitors and familial hypercholesterolemia: two examples of complex topics with differing interpretations of the science
01:39:49 - Defining risk and uncertainty in the guidelines
01:46:07 - Making clinical decisions in the face of uncertainty
01:51:58 - How the emphasis on consensus and unanimity has become a crucial weakness for science and medicine
01:59:58 - Factors holding back the advancement of apoB for assessing CVD risk, treatment, and prevention strategies
02:11:44 - Advantages of a 30-year risk assessment and early intervention

I like to hear about particle size, and wish Allan would have taken us deeper through his thoughts on that. Grateful to get stuff like this. What a gift.

@davidblackford5193 2 года назад

Hi Peter , There have been a number of replies referencing Dr Malcolm Kendricks latest book "The clot thickens" which gives a more plausible hypothesis to CVD causation than just "APoB particles get stuck in the arterial walls" and infact does a great job of debunking this myth. Would be amazing if you and Alan could take a look into this , even better interview Malcolm so we can actually get to the truth of what is happening. I would love to hear your rebuttal to his hypothesis , so far he's just been ignored. Look forward to your reply.

Your accuracy and honesty are refreshing. As a clinical pharmacist/drug info devotee, I've worked with residents who have a huge STATIC knowledge of general medicine. As they progress (especially into subspecialties) they don't really have the time to take a deep dive into many subjects, so they rely on associations to steer them. Personally I like following top notch resources (e.g. Allan Sniderman, Peter Attia, Tom Dayspring, Gil Carvalho) in specific areas.

I’m a first year med student and we just wrapped up our lipo protein lectures and my professor was adamant LDL-C is the gold standard…. Despite the explanation that the apoB value gives a count of the atherogenic particles… it’s a bit defeating as a student I must admit.

What a great discussion. I was on statins for 30 years. I am 64. I became pre-diabetic and in 2019 stepped into diabetes with an A1C of 6.6. I started a low carb diet and by late 2020 reversed my diabetes. Lowest A1C became 5.8 and all my liver and kidney values came back to normal after years of out of range. I wanted to stop the statins so doc ordered a CAC. My score was 1.something. Now my LDL and total cholesterol were high (trig. very low and HDL high) so doc ordered another CAC and now that score is 26. In only 3 years. I see my doc this week and after a TON of research on my part (both pre-treatment like this discussion and anti-statin) I think I will choose to go back on a statin (per my doc's recommendation). I will also ask about an APOb test. I have to convince myself that I can control my previous diabetes through diet, which I did. I may not want to live to 85 but 75 is certainly a goal.

Wow! To be so lucky! Most people would not have a CAC that low after 30yrs of being on a statin!

My last CAC was 458 down from 660 which is a 30% reduction achieved in 20 months...think about that!

Thank you so much for this. So courageous and so truthful. I first recognized that I had to do my own research and sometimes push back against what doctors advised when I was diagnosed with luminal a breast cancer. It is so frightening to stand on your own and choose your path based on your best assessment of all the information and your individual case. Now I learned that I have HDL of 125 mg/dl-- very high, very rare, and potentially dangerous and once again I am trying to figure out what to do on my own, in the face of clinicians who persist in telling me that high HDL is good, certainly nothing to worry about. I feel cursed by the lousy genetics but blessed to have the information in presentations like these. And, though my individual case details are rare, I feel now like I am not rare or alone in trying to figure out things myself, in the face of harried and uninformed clinicians.

@GerardCantor 2 года назад

It seems to me that the only way to change the way risk is assessed (which will never happen but should) is that for one week out of the year, doctors should go to a conference led by the leading scientists doing studies in their specialty to discuss the latest results and to figure out the best possible way to diagnose and treat diseases. Instead, we have doctors who are following what they learned in med school, their residency or read in a New England Journal of Medicine article years ago, along with whatever the pharmacological industry is currently pushing. Not the best recipe to prevent disease.

@timmothyburke Год назад

My guess on blood pressure being a mechanical engineer I’m not a doctor or a medical person is that it’s as simple as the total resistance of the circulatory system. And the resistance of the circulatory system would be a function of the resistance of all the individual parts. And I’m guessing that this resistance increases with a variety of factors including athroscrelosis, inflammation, kidney function, sodium levels, hydration regulation, and the ability of blood vessels in general to allow blood flow. So we see that blood pressure goes down with BMI probably because a smaller body has less resistance. Muscle tone would be a big factor I’m guessing assuming higher muscle tone has better blood flow.

Until I had accepted the immaturity of professional medical organizations, little surprised me more than the extent to which they were more about themselves; their agendas, their remuneration, their politics; than they were about the health and well-being of those they serve. They rigidities of US medicine is there for those without blinders to see! Whether it is the unhealthfulness of the Standard American Diet, the support of American agri-business by the cancer, diabetes and heart associations, recognition of patient rights or the primacy of ApoB in cardiac risk assessment, much work on physician’s personal emotional growth is needed. There is good reason here to see why it takes so long to get information that can save and enrich lives from the results of clinical trials to the doctor’s office and patients. Very useful podcast.

I've refused statins, and managed to lower my ApoB from 186 (on a strict keto diet) to 83 by adding 2 cans (~600 g) of legumes per day, cutting red meat and SFA and exercising even more. And by incorporating 50-50 salt (half potassium chloride, half NaCl), I've dropped BP to 110/69 in my early 60s.

Given Peter's enthusiasm for rapamycin, it would have been nice if he discussed how risk for cardiovascular disease is impacted by rapamycin use. We know that three independent studies have shown that 6-10 weeks of rapamycin treatment is enough to cause a reversal of some of the key measures of heart function (EF, FS and E/A) in old mice back to about halfway to that of the young mice (that is, it takes a 60-65-year-old back to about a 30-year-old in a human equivalent approximation). Does it lower CVD risk also?

On a lateral radiograph we can see the aorta displaced ventrally in the descending thoracic portion. Histopathologically, these aorta demonstrate more fibrous tissue than a younger aorta.

Bottom line question. Do I understand that if ApoB is even slightly elevated, starting treatment with something like a statin, will slow the atherosclerosis process thereby reduce time to onset of Events?

@marcellaflubacher8207 2 года назад

I don't get how you can have a conversation that includes cholesterol and not mention that a higher cholesterol provides a survival advantage for older folks. Wish I could provide sources, but I only remember the data.

@scoggme0 2 года назад

I think it is in the Framingham data

@JoeS97756 Год назад

I've heard that also, but it's hard to grasp since it is not uncommon for cholesterol to drop in elderly people and very sick people, thus making it appear that those with high cholesterol live the longest. The whole correlation is not causation thing. So much we don't understand about this makes it so frustrating.

ApoB "sufficiency" is a wrong term. Modifiable is a better term. There are several factors that can modify the rate of transcytosis of ApoB particles. TNF-alpha. Estrogens. Genetic mutations. Blood glucose. What has to be done - is to quantify the modifiers. Then we will know the safe level of ApoB for a given person.

@zack_120 2 года назад

33:22 - "high triglycerides, high cholesterol but low 'apo-B' in remnant type-3 dysliprotenemia: low LDL is for sure because the conversion of VLDL to LDL is low. Low apo-B makes sense with high chylomicron which contains apoB-48 that is excluded in the apo-B (100) test.

@toddboothbee1361 8 месяцев назад

I noticed this too, that if I want to get a statin to lower my apob, I'd have to engage in bad health behavior (eat chicken skins, smoked, etc.) in order to better protect my future health. When I bring down my numbers through discipline and sacrifice (diet and exercise), I'm not given statins to bring me all the way down to where I need to be. I'm left in limbo/normal land until I begin to fall ill. It is stupid if the goal is disease prevention.

@edwigcarol4888 2 года назад

"APO-B is causal but it's necessary but not sufficient" So with my familiar dyslipidemia i can focus on the other factors, on which a life style's approach has more influence.. By the way another factor belonging to the category "necessary but not sufficient": insuline resistance? Prevention simpler then than trying to lower Apo-B with pills..

@JoeS97756 Год назад

I would argue with the point of necessary as we know that many with heart attacks do not have high cholesterol. Multi factorial for sure but necessary, no.

My so called Essential Hypertension is reducing dramatically since I switched to a very low carbohydrate diet. I was pre diabetic ( Now reversed ). I have never smoked. I am normal weight. I am 64 & have had very high blood pressure since my early 30’s. I also now have very low triglycerides. These used to be high. My HDL is high & always has been. My Non HDL is 50% higher than the maximum reference range. I have been referred to lipidology by the British NHS because the Dr suspects familial hypercholesterolemia. She didn’t know what pattern A or B or Apo B particle numbers are. I hope to God that lipidology test the subtractions. I am on a very long waiting list. Meanwhile I am frightened. I stopped taking Statins due to massive muscle loss. Anne

@Peterattiamd Your articulation of dealing with uncertainty at the 1:46 mark was very deftly made. This particular observation is something that I see becoming a major issue as we see medical care move away from a vocational ethos to a retail/market reactive ethos. Evidence, statistical variation doesn't replace novel care within the context of a clinical environment. Great interview!

As a practicing physician I am frustrated with the overall knowledge and training in lipidology. As you can notice, even very smart and well studied specialists are discordant in opinions! I hope that in the next 5-10 years we will get this down… Thank you for this podcast!

@karimaogden3875 Год назад

Never knew there was a medical specialty called "Lipidology" until yesterday when I was watching another channel. How does anyone go about finding one? Doubt that there are many of them in the U.S. Assume most of them work at teaching hospitals or at The Cleveland Clinic.Even finding an Endocrinologist, Diabetologist or CDE in a lot of areas is very hard and if you do, there is a long wait. I see a Hepatologist at University of Louisville for NAFLD (doing much better) because that's the ONLY place within a 100 mile radius that does Fibroscans. Even though I am an established patient, I still have to make my follow-up appts one year in advance and if I miss or can't make that appt because something came up, I risk having to wait another 6 months because the doctor is only in-clinic on Mondays and the rest of the time, he is teaching and seeing Hepatitis patients and I am considered low risk by my doctor because I am not diabetic and my NAFLD has been reversed. That's what I was told last year when I couldn't make my yearly appt because I had a car accident (no injuries thankfully) but my car was totaled and was trying to reschedule.

@marshcreek4355 Год назад

@@karimaogden3875 Usually an endocrinologist may have specialized in training as a lipidologist. My PCP sent me to one back in 2016 once he raised concerns about my cholesterol level and family history of heart disease. He's actually been running blood work for Apo B since early 2016 once or twice a year. Good luck.

@villamartignoni 9 месяцев назад

@@karimaogden3875 it’s not yet an accredited specialty. But it is a science that needs to be addressed! So, a cardiologist, endocrinologist, internist and I think family medicine can take the boards and get accredited. There is no need for a paper saying that you are accredited, like Attia has noticed, even accredited lipidologists can also get stuck in the 1990’s.

@mkkrupp2462 5 месяцев назад

@Papkazz 2 года назад

Dear Peter, I’m a fellow MD (with at least an above average knowledge of lipidology). I usually enjoy your podcast…. But this?!. Myopic, pro-statin (“great therapy”? Really? show me a study with more than a absolute minimal effect) apoB/cholesterol-centric lecture, with next to nothing on metabolic health, micronutrient status, inflammation, type A and B lipoprotein pattern, oxidation, insulin resistance and so on, and I know you know a lot about this stuff. I know particle count is important, but I my opinion you left so many other important points. Cardiovascular disease (atherosclerosis) is an inflammatory condition (or so I’ve let myself convince), you dont mention the condition of either the Apo-B/cholesterol (healthy vs oxidized/rancid) or the state of the artery (healthy vs inflammed) as something of grave importance for the risk? Just that Apo-B get stuck in there and that’s the cause of AS. I simply don’t agree. And the short part on hypertension was at best laughable. When you can reverse HT in patient after patient with almost the same therapy (NOT drugs, but with good sleep and overall lifestyle changes).. it gives you quite a good hint on what is at least a part of the pathophysiology (although of course multifactorial). I my opinion. When you reverse insulin resistance, optimize micronutrients, lower kortisol and catecholamines and lower chronic inflammatory most hypertension resolve itself. It’s absolutely not just “age”. Maybe I’m suffering from a bit of cognitive dissonance here. But I was disappointed.

@AZ89231 2 года назад

I can help I think! More than absolutely minimal effect: one example (there are many more) is 4S with which the NNT for all cause mortality was 30 and NNT to prevent major coronary event was 15 over 5.2 years? Idk about you but that is a great therapy - absolutely amazing! Especially in the era where apoB levels were not targeted, probably would have seen better outcomes if they were (based on Johanneson 2021)

I agree 100%. I am not a doctor, but a patient with high Total Cholesterol,(familial) and high LDL. But healthy-high HDL levels, Triglyceride: HDL ratio is .76, normal Homocysteine, HBA1C, CPR markers etc. My ApoB : APOA1 ratio is 0.7. The first thing my GP said: "Gotta get you on statins now!" I said: " And you want to kill off my mitochondrial functioning, and give me a very high risk for Alzheimer's, in the 'hopes' that this drug will lower my chances of a heart attack ( and it has statistically shown to NOT in any significant way), never!" How many cardiologists are even aware that when taking a statin, you MUST also take enzyme Co Q 10, to save your mitochondria? It is insanity....Willful ignorance and big-pharma pay-backs that are bordering on criminal negligence...The motto "Do No Harm", is a big joke.

Hey young doctor here, absolute beginner. I kind of like the topic of prevention. This video is so very helpful. I can confirm that too much focus is on cholesterol. The scientific consensus is on LDL particles being the cause not cholesterol.

I’m curious what transient receptor potential channels A1 and V1 play in the lipid apoB scenario. TRPV1 and TRPA1 are of essential importance in endothelial and cardiomyocyte function. Add inflammation to this and we’re getting quite close to the main culprits here.
