Acute Myocardial Infarction in the Young

The purpose of this study was to assess frequency, risk factors, complications and mortality rate of young patients with acute myocardial infarction (AMI), in Yazd.
45 years (old). Risk factors, type of AMI, management, complications and hospital
outcomes of the 2 groups were evaluated.
The young patients represented 11.6% of all cases, and 10% of these individuals were female. Smoking (60.2% vs. 33.6%, P. value=0.000), positive family history (40.2% vs. 28.6%, P. value=0.017) and obesity (25% vs. 13.9% P. value=0.022) were more common in the young group. Diabetes mellitus (24.1% vs. 46.9%, P. value=0.000) and hypertension (15.1% vs. 43.3%, P. value=0.000) were more common in the old patients. Young male patients had less in-hospital mortality (1.2% vs. 9.1%, P. value=0.005) than old male patients, but in the females the difference of mortality between young and old was not significant (10% vs. 19.9%, P. value=0.3).
In this study, about one-tenth of the patients with AMI were £ 45 years old. Smoking, obesity and positive family history were more common in the young patients, and overall mortality rate was low in the young (Iranian Heart Journal
2005; 6 (1,2): 52-54).
