I have "high cholesterol," secondary to my keto-carnivore diet, which I've been on for about 3 years. I have a new doc. When he saw my numbers, I could feel his anxiety and agitation about them. He talked up statins pretty hard. He was on them himself, he said, and it was a way of helping to make sure I lived a long time.
I knew this was coming, so I'd done my homework. I declined the statin. I presented my case as succinctly as I could, knowing doctors have about 10 minutes then it's on to the next patient.
I tried to make three points:
1. The cholesterol/LDL hypothesis of heart disease is full of holes. The majority of the studies (like 80%) show either no correlation or an inverse correlation between cholesterol level and heart disease. It's even clearer as you get older: for people over 60 or so, higher cholesterol has been associated in many studies with better outcomes.
2. When you control for metabolic health (insulin resistance, inflammation), the relationship between cholesterol and heart disease disappears. Every biomarker and subjective sign shows that my health is much better now than it was prior to eating this way. I reviewed each of them briefly with him, but I'll spare you the details. The only indicator heading in a "negative" direction was LDL, and even that is only a problem if you buy the cholesterol theory, which I don't.
3. LDL-C doesn't tell you anything, really. Heart disease does correlate with Pattern B (small, dense) but not with Pattern A (large, bouyant). Instead of running an expensive test to subfraction the LDL, you can just look at triglyceride, HDL, and the tri/HDL ratio. All three of those, in my case suggest that my LDL is of the Pattern A type, the type not associated with atherosclerosis.
Fortunately, he's a smart guy, and he listened. He said that what I was saying made sense, and he was okay with it. He said he wished he had time to keep up with the literature better, so he could talk better about these subjects with patients like me. He said he appreciated my being engaged.
I'm sure my CAC of zero helped, too. For those who don't know, CAC measures the actual presence of heart disease. Cholesterol and other such things are only guesses at what the risk of the disease might be. CAC is a measure of the actual disease process. Get one, if you have any concerns -- or even if you don't. A large percentage of people have elevated CACs in the absence of high cholesterol or other traditional risk markers. That's the value of the test -- it detects lots of people who have advanced heart disease and who would not have known it otherwise (because their traditional markers were fine). It then allows you to do something about it, to get that disease process under control.
I once heard that if you combine all the traditional risk markers together, they only explain about 17% of the variance. We get a false sense of security from these markers. They're presented as if the medical establishment has it all figured out. Not even close. Get a CAC. They're only $100. It's not a bunch of statistical guesswork based on correlational data. It measures the actual disease.
I didn't go into detail with him about my objection to statins, because he didn't press further, but here are my thoughts about statins.
1. Their effectiveness is greatly exaggerated. They do lower cholesterol, but who cares. Their effect on heart events is minimal, and it is thought that this effect may have to do with their anti-inflammatory properties, rather than its effect on cholesterol. Their overall effect on all-cause mortality is nothing. There have been several studies where people taking statins have had worse outcomes (amazing that these studies saw the light of day; one has to assume that many more got buried).
2. Lots of people have side effects. Some of these side effects are quite serious (e.g., diabetes, cognitive decline). Statins interfere with the production of a certain biochemical (co-Q-10? I can't recall) that is essential to cognitive function.
3. The statin business is amazingly lucrative. There are billions and billions involved in marketing and in getting "hired guns" (well-paid doctors) to push them in conferences. Doctors are sold this from cradle to grave. All the studies are done by the drug companies themselves (I'm sure there's no bias there).
4. The historical record of cholesterol-lowering drugs (many of which have come and gone) is abysmal. Tens of thousands of people have died prematurely or had their lives damaged by this parade of cholesterol-lower medications. It's extremely profitable.
5. Cholesterol is an essential ingredient of life. It is present in every cell of your body. If you removed cholesterol from your body, you would die instantly and melt into a puddle of goo on the floor, like the wicked witch of the west. Cholesterol is a molecule that is basic and fundamental to life. It is present in every single animal on Earth. We have demonized something that is at the bedrock of life.
6. If/when cholesterol is a problem, it is only a SIGN or symptom of a problem; it is only a correlate and not a cause. Dave Feldman has an image that captures it pretty well. Cholesterol (or LDL) is like a firefighter arriving at the scene of a fire, and some of the firemen get trapped in the fire. Would you blame the firemen for the fire? Would you try to reduce the number of firefighters? No, you'd focus on putting out the fire. That's simplified, but it makes the point.
Sorry, that was a longwinded post. I guess I have a lot to say about this subject, lol.
p.s. To be fair, I should add that there is some data to suggest that statins may be helpful for men who've already had a heart attack or for those with CAC scores over 400 (under 400, no benefit seen).
