Acutally, the thought about LDL being the most predictive factor for MI isn't quite true. Although that gets all the publicity b/c statins are so popular, it is the low HDL that is the most predictive of MI. That's also the reason why women s/p menopause begin to have increased risk of MI. The estrogen before hand was boosting thier HDL's.
Also for test purposes, Hormone Replacement Therapy does NOT reduce the risk of MI in women.
