Clinical and prognostic comparison between Middle-East and Indian subcontinent patients following acute coronary syndrome

Background Data comparing acute coronary syndrome (ACS) patients from the Middle East with those from the Indian subcontinent is scarce. The aim of this study was to compare clinical characteristics and outcomes between Middle East Arabs and those from the Indian subcontinent presenting with ACS. Methods and Results This was a prospective, multinational, observational study of ACS patients admitted to 65 hospitals in 6 Middle Eastern countries during the period between October 2008 and June 2009, as part of Gulf RACE–II (Registry of Acute Coronary Events). Analyses were performed using univariate and multivariate statistics. The Middle Eastern Arab group was significantly older (60 versus 49 years; p p p p p p p p p p  = 0.001), cardiogenic shock (7.0% versus 3.0%; p p  = 0.005). Conclusions Middle East Arabs were associated with higher rates of coronary risk factors, more complicated in-hospital course and a higher long-term mortality when compared to patients from the Indian subcontinent.
