Abstract/OtherAbstract:
Little is known regarding gender differences in left ventricular (LV) function after anterior wall ST-segment elevation myocardial infarction (STEMI), despite it being a major determinant of patients' morbidity and mortality. We therefore sought to investigate the impact of gender on LV function after primary percutaneous coronary intervention (PCI) for first anterior wall STEMI. Seven hundred eighty-nine consecutive patients (625 men) with first anterior STEMI were included in the analysis. All patients underwent an echocardiographic study within 48 hours of PCI. Women were older and more likely to have diabetes, hypertension, chronic renal failure, and a higher Killip score. Women had prolonged ischemic time, which was driven by prolonged symptom-to-presentation time (2.75 [interquartile range 1.5 to 4] vs 2 [interquartile range 1 to 3.5] hours, p = 0.005). A higher percentage of women had moderate or worse LV dysfunction (LV ejection fraction <40%; 61.6% vs 48%, p = 0.002). In a univariable analysis female gender was associated with moderate or worse LV function (p = 0.002). However, after accounting for variable baseline risk profiles between the 2 groups using multivariable and propensity score techniques, ischemic time >3.5 hours, leukocytosis, and pre-PCI Thrombolysis In Myocardial Infarction flow grade <2 were independent predictors of moderate or worse LV dysfunction, whereas female gender was not. Data on LV function recovery at 6 months, which were available for 45% of female and male patients with moderate or worse LV dysfunction early after PCI, showed no significant gender related difference in LV function recovery. In conclusion, women undergoing PCI for the first event of anterior STEMI demonstrate worse LV function than that of men, which might be partially attributed to delay in presentation. Hence greater efforts should be devoted to increasing women's awareness of cardiac symptoms during the prehospital course of STEMI.
