Is there any evidence anywhere that high cholesterol causes heart attacks?

Effect of cholesterol crystals on plaques and intima in arteries of patients with acute coronary and cerebrovascular syndromes.

Crystals don't form in solution until the concentration gets high enough to precipitate. There's too much solute or not enough solvent

Is it true that 50% of all heart attack victims have “normal” cholesterol levels?

That's what these folks say.

IIRC, they're calling a total cholesterol under 200 normal.

So cholesterol is a predictor of heart attack but not a cause.
