文摘

Gender differences in presentation, management and outcome in patients with ST-segment elevation myocardial infarction (STEMI) have been reported.

Aim

To determine whether female gender is associated with higher inhospital mortality.

Methods

Data from ORBI, a regional STEMI registry of 5 years’ standing, were analysed. The main data on presentation, management, inhospital outcome and prescription at discharge were compared between genders. Various adjusted hazard ratios were then calculated for inhospital mortality (women versus men).

Results

The analysis included 5000 patients (mean age 62.6 ± 13 years), with 1174 women (23.5%). Women were on average 8 years older than men, with more frequent co-morbidities. Median ischaemia time was 215 minutes (26 minutes longer in women; P < 0.05). Reperfusion strategies in women less frequently involved fibrinolysis, coronary angiography, radial access and thrombo-aspiration. Female gender, especially in patients aged < 60 years, was associated with poorer inhospital prognosis (including higher inhospital mortality: 9% vs. 4% in men; P < 0.0001), and underutilization of recommended treatments at discharge. Moreover, excess female inhospital mortality was independent of presentation, revascularization time and reperfusion strategy (hazard ratio for women 1.33, 95% confidence interval 1.01–1.76; P = 0.04).

Conclusions

One in four patients admitted for STEMI was female, with significant differences in presentation. Female gender was associated with less-optimal treatment, both in the acute-phase and at discharge. Efforts should be made to reduce these differences, especially as female gender was independently associated with an elevated risk of inhospital mortality.
