Abstract

Background: Conflicting information exists about whether sex differences affect long-term outcomes in patients undergoing primary percutaneous coronary intervention (PCI). Methods: This retrospective study enrolled consecutive patients with ST-elevation myocardial infarction undergoing primary PCI within 24 hours from symptom onset. Hazard ratios (HRs) of events with 95% confidence interval (CI) were calculated in the overall population and in a propensity score matched cohort of women and men. Results: Among 481 patients, median age 66 years old, 138 (28.7%) were women. Women were older than men (72 vs 63 years, P <0.001), had a higher prevalence of hypertension (68% vs 54%, P = 0.006), diabetes (27% vs 19%, P = 0.04), and Killip class ≥ 3 at admission (19% vs 10%, P = 0.007). After a median follow-up of 1041 days women experienced a significant higher incidence of the composite of death, nonfatal myocardial infarction, and hospitalization for heart failure (31.9% vs 18.4%, unadjusted HR 1.86; 95% CI, 1.26-2.74; P = 0.002), driven mainly by heart failure (unadjusted HR 2.47; 95% CI, 1.12-5.41; P = 0.024), without significant differences in death (unadjusted HR 1.49; 95% CI, 0.88-2.53; P = 0.13), or nonfatal myocardial infarction (unadjusted HR 1.59; 95% CI, 0.78-3.27; P = 0.19) and no increase in target lesion revascularization (9.4% vs 12.5%, unadjusted HR 0.77; 95% CI, 0.42-1.44; P = 0.42). After propensity score matching the hazard of the composite endpoint was largely attenuated (HR 1.32; 95% CI, 0.84-2.06; P = 0.23). Conclusions: Women undergoing primary PCI experience worse long-term outcomes than men, but this difference is largely explained by their more adverse baseline cardiovascular profile.
