Objective: To assess gender-related differences in the presentation, management, and in-hospital outcomes among acute coronary syndrome (ACS) patients from Oman. Methods: Data were analyzed from 1579 consecutive ACS patients from Oman during May 8, 2006 to June 6, 2006 and January 29, 2007 to June 29, 2007, as part of Gulf RACE (Registry of Acute Coronary Events). Analyses were conducted using univariate and multivariate statistical techniques. Results: In this study, 608 (39%) patients were women with mean age 62 ± 12 vs. 57 ± 13. years (p< 0.001). More women were seen in the older age groups (age <55. years: 25% vs. 43%, 55-74. years: 60% vs. 49% and >75. years: 15% vs. 8%; p< 0.001). Women had higher frequencies of diabetes, hypertension, hyperlipidemia, obesity, angina, and aspirin use, but less history of smoking. Women were significantly less likely to have ischemic chest pain, ST-elevation myocardial infarction (STEMI), non-STEMI and were more likely to have dyspnea, unstable angina, ST depression and left bundle branch block. Both groups received ACS medications and cardiac catheterization equally; however, women received anticoagulants (88% vs. 79%; p< 0.001), angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin II receptor blockers (ARBs) (70% vs. 65%; p=0.050) more and clopidogrel less (20% vs. 29%; p< 0.001). Women experienced more recurrent ischemia and heart failure but with similar in-hospital mortality (4.6% vs. 4.3%) even after adjusting for age (p=0.500). Conclusions: Women admitted with ACS were older than men, had more risk factors, presented differently with no difference in hospital mortality. This is similar to Gulf RACE study except for mortality. Women received anticoagulants/ACEIs /ARBs more but were under-treated with clopidogrel.
