i received three stents as the result of my attack. i was given an angiogram two years earlier and told i had insignificant blockage for my age (no spot greater than 30% blockage). at the time of my heart attack, one artery was 100% blocked, and another had blockages of 70 and 50% (in the same artery). i was only 61, not overweight, and had quit smoking several years before. the primary culprit was probably stress, so you need to do whatever helps with this, even if its a med you don't like, such as xanax.
