Association of gender with clinical outcomes of patients with acute ST-segment elevation myocardial infarction presenting with acute heart failure.

BACKGROUND There is limited data evaluating the sex differences in outcomes of patients with ST-segment elevation myocardial infarction presenting with acute heart failure. We compared the outcomes between women and men with ST-segment elevation myocardial infarction presenting with acute heart failure (Killip classification ≥II). METHOD All ST-segment elevation myocardial infarction patients presenting to the emergency department of a cardiovascular center in Jakarta, Indonesia, from 1 February 2011 to 30 August 2019 were retrospectively analyzed. RESULTS Of 6557 patients recorded, 929 were women, and 276 (4.2%) presented with acute heart failure. Compared with men with acute heart failure (N = 1540), women who presented with acute heart failure were older (63 ± 10 vs. 57 ± 10 years, P 4 (85% vs. 73%, P < 0.001), received fewer primary angioplasty and in-hospital fibrinolytic therapy (40% vs. 48%, P = 0.004 and 1.1% versus 3.5%, P = 0.03, respectively), and had longer median door-to-device and total ischemia times (96 vs. 83 minutes, P = 0.001, and 516 versus 464 minutes, P = 0.02, respectively). Multivariate analysis showed that women and men with acute heart failure were each associated with increased risk of in-hospital mortality (odds ratio: 4.70; 95% confidence interval: 3.28-6.73 and odds ratio: 4.75; 95% confidence interval: 3.84-5.88, respectively), and this remained relatively unchanged even among patients with acute heart failure who had undergone reperfusion therapy (odds ratio: 5.35; 95% confidence interval: 3.01-9.47 and odds ratio: 5.19; 95% confidence interval: 3.80-7.08, respectively). CONCLUSION In our population, women with ST-segment elevation myocardial infarction presenting with acute heart failure had relatively similar risk of early mortality with their male counterpart (≈5-fold), thus should receive evidence-based treatment.
