None of the blockages occluded any arteries which would have resulted in a heart attack and damage to the heart muscle. They just narrowed the pipeline for the flow of blood to the heart muscle.

Generally, folks notice this by a decrease in cardio vascular fitness if they are at all active. If not you suddenly find yourself gasping for air when walking up a flight of stairs or something like that.

In my case, I knew I had a blockage because I used to run religiously and I couldn't even run a mile without getting winded when I had a blockage.

Thank you for the information.

With a narrowing you can see the blood flow both proximal and distal to the blockage. When a heart attack occurs the artery occludes and you can't see the whit dye distal to the lesion.

I knew it when I had the heart attack.(P.S. I didn't run religiously).

Prayers for President Clinton and his family.
