Association between bleeding and mortality among women and men with high-risk acute coronary syndromes: insights from the Early versus Delayed, Provisional Eptifibatide in Acute Coronary Syndromes (EARLY ACS) trial.

BACKGROUND: Female sex is an established risk factor for bleeding, which is an important safety end point in patients presenting with non-ST-segment elevation acute coronary syndromes (NSTE ACS). However, it is unknown whether the association between bleeding and mortality is modulated by sex in this patient population. METHODS: We examined the interaction between sex and bleeding and 30-day mortality outcomes among 2,975 women and 6,431 men with high-risk NSTE ACS enrolled in the EARLY ACS trial. The Global Utilization of Strategies to Open Occluded Arteries (GUSTO) criteria were used to identify moderate or severe bleeds. RESULTS: Women were older and had more comorbid disease compared with men. Bleeding rates were higher among women (8.2%) than among men (5.5%; P < .01). However, the association of bleeding and 30-day mortality was stronger among men (odds ratio 5.8, 95% CI 3.9-8.8) than among women (odds ratio 1.5, 95% CI 0.8-2.9; sex * bleeding interaction P < .01). Sex differences in the association of bleeding and mortality persisted in a landmark analysis of 120-hour survivors. CONCLUSIONS: In a contemporary high-risk NSTE ACS cohort, women had higher bleeding rates than did men. Paradoxically, the association between bleeding and mortality was worse among men than among women.
