Abstract

Previous data reported worse outcomes in female patients after acute ST elevation myocardial infarction (STEMI), related at least in part to less aggressive and nonparallel treatment. We investigated the presence of gender differences in left ventricular (LV) systolic and diastolic function in patients presenting with first STEMI, treated with primary percutaneous coronary intervention (PCI). Study population included 187 consecutive patients (81% men) presenting with STEMI and treated by primary PCI and guideline-based medications. Their mean age was 58 ± 10 years. All patients underwent a comprehensive echocardiographic evaluation within 3 days of admission. Female patients were older (62 ± 11 vs 59 ± 10 years, p = 0.006), with more co-morbidities and longer symptom duration (490 ± 436 vs 365 ± 437 minutes, p = 0.013). Echocardiography demonstrated that female patients had significantly lower LV systolic function (47 ± 8% vs 45 ± 8%, p = 0.03), lower septal and lateral e′ velocities, higher average E/e′ ratio (all p <0.001), elevated systolic pulmonary artery pressure (p = 0.03), and worse diastolic dysfunction (p = 0.007). No significant changes were present in left atrial volumes. In a logistic multivariate analysis model, female gender emerged as an independent predictor of septal e′ <8 cm/s (odds ratio 10.11, 95% confidence interval 1.23 to 82.32, p = 0.002) and E/average e′ ratio >15 (odds ratio 6.47, 95% confidence interval 1.63 to 25.61, p = 0.008). In conclusion, female patients undergoing primary PCI for first STEMI demonstrated worse systolic and diastolic LV function, despite receiving similar treatment as male patients.
