| Popis: | Aim: Previous studies demonstrate higher 30-day all-cause mortality and re-infarction amongst women with ST-elevation myocardial infarction (STEMI). This study examines if gender differences exist in cardiac hemodynamic parameters assessed during an acute STEMI. Methods: The clinical, angiographic and hemodynamic features of 470 consecutive patients undergoing emergency primary percutaneous coronary intervention for an acute STEMI were evaluated with respect to gender. Patients routinely underwent right heart catheterization using a Swan-Ganz catheter, during the emergency reperfusion therapy procedure. Infarct size was estimated by evaluating the peak creatinine kinase (CK) levels. Results: The 135 STEMI female patients were significantly older than males (69±13 vs. 60±12 years, P Conclusion: Women with an acute STEMI have a higher 30-day cardiac event rate despite similar extent of coronary artery disease, infarct size and site. However they do have higher left ventricular filling pressures, which is consistent with their poorer outcomes. The mechanism/s of this hemodynamic difference requires further investigation.
