After the stents had been placed on.

Well, people with known coronary artery disease (and having had a heart attack, regardless of what treatment was given, puts a person in this category) is a very potent risk factor for future heart disease, so yes, but not because of the heart attack per se, but because of the conditions that lead to it.

Stents are great, and they can help with symptoms, but there is no evidence to suggest that they save lives, they don't protect against future heart attacks (although the stents themselves usually stay open, the unstented coronary arteries often develop disease).

Anyone who has had a heart attack should be under the care of a cardiologist and should do everything he can to reduce his risk factors, no smoking, lowering cholesterol and blood pressure aggressively, exercise, diet, weight loss, and tight control of diabetes for those who have it to reduce, as much as possible, the chances of having another heart attack. Yes! It is definitely a bigger risk of having a second heart attack. When you have a heart attack it actually temporarily kills your muscle [heart]. Sometimes causing damages. So killing the muscle for a second time and getting everything back to normal again is of course a bigger risk. Seeing as you're dangerously damaging such an important muscle for a second time. yes one can have another heart attack

BUT chances are less if you follow Drs diet given to you as well as taking your heart meds YES.
