My husband, a fireman, suffered a dissection of the aorta after inhaling high concentrations of exhaust fumes from a vent saw while at a fire. A blood clot developed over the tear, causing a 93% blockage. He was treated with a stent, spent 5 days in critical care, before spending a breif period of time on the cardiology ward. We were told there were no signs of plaque, medical irregularities (aside from the dissection), he has no medical history. Hes very fit (215, 6ft2), young (29), we've always eatten impeccably (only whole grains breads and pastas, lots of vegetables, lean meats, fish ect). Its been almost 3 months since the heart attack, and his muscle enzymes are still high. Why?
