Young men (≤40 years) with AMI frequently present with angiographically normal coronary arteries, are often heavy smokers, and have an excellent prognosis.
These data suggest that young patients with AMI are very frequently heavy smokers, have a high incidence of angiographically normal coronary arteries, and that the short- and long-term prognosis is excellent.
Fournier et al. (1996) studied this question.
