How can viagra lead to heart attacks?

Question:

Answers:
Viagra is a substance called a phosphodiesterase inhibitor. It basically causes dilation of the blood vessels of the penis. The thought about the link between this and heart attacks (myocardial infarction - MI) is that the blood that is should be going to the heart is shunted to the penis to keep it erect. If a person who already has poor circulation to the heart because of narrowed blood arteries (arteriosclerosis) it would decrease the blood to the heart even further, resulting in lack of oxygen (ischemia) and heart muscle death (infarction).

Other Answers:
I've heard Viagra can cause blindness but not heart attacks. Actually it's just the opposite in some studies. See the link I've provided.

I thought it could give you heart attacks because it makes you have a hard on for like hours,& you work & work & work at something for ever. It's just like those things you hear about old guys having a heart attack & dying during sex.

Well, instead of Viagra, you could take.Mycoxafloppin, Mycoxafailin, Mydixadrupin, Mydixarizin, Dixafix, Ibepokin.

viagra makes your blood pump faster to give you an erection, eg this makes your heart go faster leading to over working of your heart which is how a heart attack happens

what?
