To evaluate the angiographic profile and outcome of primary percutaneous coronary intervention in female patients with acute myocardial infarction.

Single-vessel disease was observed in 183(35.1%) patients, and three-vessel disease in 144(27.6%). Post-procedure thrombolysis in myocardial infarction flow (0-II) was observed in 29(5.6%) patients, bleeding in 2(0.4%), and in-hospital mortality was in 22(4.2%). Telephonic follow-up was successfully conducted in 436(87.5%) of the discharged patients, and, of them 15(3.4%) had expired and recurrence was reported by 10(2.3%) patients and 8(80%) of them underwent re-intervention.
