@tim1028 In the 90,s Ihad triple by pass at that time after surgery Dr put me on Aspirin 81mg it acts as a blood thinner to prevent clots Its been 23 yrs now Ive taken the aspirin every night and still here Long before this the Dr told me my calcium level was good so Not to take calcium as you get it done n food greens in particular.You also need magnesium for your heart and other organs .I went through 3heart catheterization,stress test before surgery then echocardiogram none of it is worth worrying about ,anxiety and panicking can do more harm to you emotions play on these. Good luck
