Cholesterol, Statins, Strokes & IH

Medscape Medical News, a medical information newsfeed, sends me daily suggestions for articles to read, and I save the URLs for interesting items. In the batch I received on September 18, 2023, is a report regarding the risk profile of statin drugs, by Megan Brooks. The report advises us that “A newly published scientific statement from the American Heart Association (AHA) focuses on the impact of aggressive low-density lipoprotein cholesterol (LDL-C) lowering on the risk for dementia and hemorrhagic stroke.”

The article, on the safety of Statins

The article, entitled “AHA Reviews Impact of Aggressive LDL Lowering on the Brain, by Larry B. Goldstein, et al. was published on 14 Sep 2023 in the journal “Arteriosclerosis, Thrombosis, and Vascular Biology”. You can access it via https://doi.org/10.1161/ATV.0000000000000164 .

The authors concluded that lowering LDL-cholesterol, with Statins, reduces the risk of atherosclerosis without significant risk of strokes or of adverse effects on cognition. This is a well-written paper and the conclusion drawn by the authors, that physicians should continue the practice of lowering LDL by means of Statin therapy, is reasonable.

However as often happens, the “elephant in the room” has not been noticed by the authors: they gave no consideration to metabolic causes of elevated cholesterol and made no mention of the effect of correction or elimination of such causes.

The Elephant in the Room

(A) A significant sequel of hypothyroidism, whether “true”, or “intracellular”, is impaired glucose and cholesterol metabolism, resulting in atherosclerosis, weight gain and sometimes, a high A1C.
(B) Correction of hypothyroidism frequently eliminates the deviations from normal glucose and cholesterol management, for which Statin medications are prescribed.
(C) It is therefore prudent, whenever hypercholesterolemia is discovered, to investigate thyroid hormone metabolism with a view to diagnosis of either true hypothyroidism, or intracellular hypothyroidism, or both.

Very necessary, but frequently omitted, tests

Metabolic/Functional Medicine physicians agree that every patient with hypercholesterolemia should have a “thyroid profile”, including TSH, Free T4, Free T3 and Reverse T3. The thyroid profile results allow the physician to calculate the T3/rT3 ratio and determine whether true hypothyroidism, or intracellular hypothyroidism, are etiologic agents in the individual’s deranged cholesterol metabolism.

If either condition is found, correction of true hypothyroidism with T4, or intracellular hypothyroidism with T3, will improve the patient’s glucose and cholesterol management, often to the point where a statin prescription is not needed.

The Bottom Line

(1) A “thyroid profile” should be performed as part of routine “checkup” testing. If a thyroid profile has not been ordered, any aberrant glucose and/or cholesterol test results should trigger a request for it.

(2) True Hypothyroidism, or Intracellular Hypothyroidism, if found, should be corrected prior to deciding whether the patient needs a Statin prescription, or not.

I am a Toronto-trained Urologist. I practiced in downtown Toronto, from 1977 to 1997, when I went to Saudi Arabia as chief of Urology at the Armed Forces (teaching) hospital in Tabuk. Returning to Toronto in Y2000, I switched to family practice. In 2007, began to prescribe Hormone Restoration Therapy and in 2012, I became a member of the American Academy of Antiaging Medicine [A4M]. I successfully wrote the A4M's written examination in December, 2013 and In May, 2016 I passed the oral examination, for accreditation as a BHRT consultant. In 2014 I began BHRT practice in Collingwood, Ontario and in January, 2017, joined the Stone Tree Naturopathic Clinic. Now I am 82 and have retired, but it seems wasteful to jettison my learning and experience: the medical establishment knows nothing of BHRT / Functonal medicine and I feel obliged to offer my knowledge in the interest of those who are willing to think outside the box.

I am a Member of CSAMM [the Canadian Society for Aging and Metabolic Medicine], the OMA&CMA, SUSO, CUA, RCP&S/C.
