Cardiology rounds, Haydarpasa Numune Training and Research Hospital, Turkey.
Head of department, senior clinicians, residents and interns all stand around a gold plated replica of a Simvastatin package. Slowly each clinician raises their hands, palms uppermost, out to their sides, then arches them upwards to curl over and bring the tips of fingers to meet on mid line of their head, making a kind of a heart sign.
There is a deep sense of intense religious presence, a faint smell of incense and rapt attention to the reading of the simvastatin data sheet, excepting the adverse reactions page, which seems to have disappeared. All then intone:
We believe in the lipid hypothesis, the sole lipid hypothesis and nothing but the lipid hypothesis. We believe in the great saviour Simvastatin. We believe it is the answer to all ills, especially thyroid deficiency.
OK, I made all of that up.
Except the bit about thyroid deficiency.
Where did this rant come from? This paper.
Thyroid deficiency is a major driver of arteriosclerosis. Replacing the missing thyroid hormone reverses the arteriosclerosis. You would think that nothing could be simpler. Not so. You can also reverse the signs of arteriosclerosis with simvastatin WITHOUT replacing the thyroid hormone. It doesn't work quite as well as fixing the genuine problem but, hey, it's a glossy statin not a drab thyroid supplement. I don't suppose you feel much better on a statin with or without having your thyroid problem corrected.
Best quote from the abstract:
"No correlation was demonstrated between the changes in total or LDL-cholesterol concentration and IMT (degree of arteriosclerosis) in the simvastatin group."
Translation: The cholesterol hypothesis is garbage.
My thanks to Chris Masterjohn for dropping that one on me on New Year's Day. Luckily I didn't break any fillings while grinding my teeth!
