It is a very sad event but what level of screening and mandatory checks would a 61 year old have gone through such that a heart attack was a surprise?
I am soon to be 59 and have ECGs every 6 months, have recently had a stress-test ECG and Echo CardioGram to check for valve function and ventricular wall thickening and was put on the lowest level of hypertension medication as soon as my BP went even marginally high. If I were to keel over tomorrow, I think my wife and my employers would ask how.
Sounds like you've been eating cheeseburgers all your life with all that going on. I don't think anybody would be asking.
