Gender-based differences in long-term outcome after ST-elevation myocardial infarction in patients treated with percutaneous coronary intervention.

Abstract Background: In the era of fibrinolysis, women suffered from higher early and late mortality rates than men after acute ST-elevation myocardial infarction (STEMI). Primary percutaneous coronary intervention (PCI) has been determined to be the most effective therapy strategy in STEMI. It is not clear if female gender is an independent predictor of a worse long-term prognosis among patients who were systematically treated with PCI. We, therefore, examined the effect of PCI on long-term outcome between women and men. Methods: Between 1999 and 2001, 500 consecutive patients at the Wuppertal Heart Centre were treated with PCI after acute STEMI. A long-term follow-up (up to 7 years) was achieved in 97% of the patients. Results: In comparison to men, women were 7 years older (65 ± 12 vs. 58 ± 11) and had significantly more diabetes mellitus. The time between onset of symptoms and intervention tended to be longer in women than men. There was no difference in 30-day mortality (8.9% vs. 6.6%), cardiac late ...
