Pizarro VR, et al. - Researchers assessed the clinical features of patients <35 years with ST-elevation myocardial infarction (STEMI) in this observational study. This study was conducted from January 2004 to September 2016 in three different centers. By using the prospective database of the Interventional Cardiology Department, medical history and phone interviews, data were assessed. A total of 61 patients ≤35 were included, with predominance of male (88%), smokers (80%) and overweight (67%). Among those, 26% were drug consumers and only 3% (2 patients) had no conventional risk factors. Over 5.9±4.2 years of follow-up revealed a total survival of 96.6% (2 deaths) and only 17.2% (10 patients) major adverse cardiovascular events (MACE) incidence. According to findings, young subjects rarely experience STEMI. The characteristics of these patients included presence of several modifiable predisposing factors, a low clinical risk profile, and excellent short and long-term prognosis with state-of-the-art treatment.
