Objective: To compare angiographic characteristics and outcomes of primary percutaneous coronary intervention between young and old patients presenting with acute ST Elevation Myocardial Infarction.
Methods: The prospective observational study was conducted at the National Institute of Cardiovascular Diseases, Karachi, from December 17, 2016, to June 16, 2017, and comprised acute ST-Elevation Myocardial Infarction patients undergoing primary percutaneous coronary intervention (PCI). Data was collected on demographic, angiographic, and in-hospital outcomes. Those <40 years were considered young. Data was analysed using SPSS 21.
Results: Of the 415 patients, 50(12%) were young. Proportion of male was higher among the young (p=0.02) and so was the case with positive family history (p=0.002). The young had lesser cases of diabetes (p=0.028) and hypertension (p=0.034). Single vessel disease was more common among young (p<0.001). No significant difference was observed in post-procedure outcome related to age (p>0.05).
Conclusions: Acute Myocardial Infarction in young was more likely associated with male gender, positive family history and less likely with hypertensive and diabetic status.
