Sex differences in treatment and prognosis of acute coronary syndrome with interventional management.

ABSTRACT

OBJECTIVE: Female sex has been associated with differences in diagnostic and management of acute coronary syndrome (ACS). Our aim was to analyze sex differences in ACS with interventional management in a tertiary care hospital. METHODS: Patients with ACS admitted to a Spanish tertiary care referral center were included prospectively and consecutively. All patients included in the study underwent a coronary angiography. RESULTS: From the total cohort of 1214 patients, 290 (24%) were women. Women were older (71 ±â€¯12.8 vs 64 ±â€¯13.4 years, p < 0.001) and showed lower ischemic risk and higher hemorrhagic risk scores (GRACE 159 ±â€¯45 vs 171 ±â€¯42, p = 0.005; CRUSADE 41 ±â€¯19 vs 28 ±â€¯17, p < 0.001). There were no significant differences in time to coronary angiography and revascularization rates between sex groups. A lower proportion of women received high-potency antiplatelet agents (29% vs 41.3%, p = 0.004). In-hospital evolution and one-year mortality were similar between groups. CONCLUSIONS: In our population, there were no gender differences in management and prognosis of ACS. Differences in risk profile among groups could have an influence on antiplatelet therapy.
