Monetecfo - if you don't care to answer this, I understand, but I thought I'd ask, since your reply may benefit others who are wondering if there is any way to know what their risk of CHD may be, and possibly how to avoid having a heart attack. Did you have annual blood tests prior to the heart events you described? If so, were there any warning signs (that either your doctor or you noted) from that information? From what I understand, the triglyceride/HDL ratio, in particular, is a good predictor of future mortality due to CHD. For that reason (among others), I have an annual round of blood tests done, and I monitor that ratio and a few other things pretty closely. I'm just wondering if you do the same? You mentioned that you were a pretty active, healthy guy, and I try to stay active as well (and watch my diet), but if I saw an indication that my blood test numbers were deteriorating, I know I would probably make some further lifestyle and diet changes to head off potential problems (and probably get the Calcium artery scan done as well). I know that sometimes things still happen despite the lack of warning signs, but I still think monitoring certain things may be helpful in many cases. Thanks..........
