- BACKGROUND:Most diabetes and cardiovascular studies have been conducted in white patients, with data being extrapolated to other population groups.METHODS:For this analysis, patient-level data were extracted from 5 randomized clinical trials in patients with acute coronary syndrome; we compared obesity levels between Asian and white populations, stratified by diabetes status. By using an adjusted Cox proportional hazards model, hazard ratios (HRs) for cardiovascular outcomes after an acute coronary syndrome were determined.RESULTS:We identified 49,224 patient records from the 5 trials, with 3176 Asians and 46,048 whites. Whites with diabetes had higher body mass index values than those without diabetes (median 29.3 vs 27.2 kg/m(2); P <.0001), whereas Asians with diabetes and without diabetes had similar body mass index (24.7 vs 24.2 kg/m2). Asians with diabetes (HR, 1.63; 95% confidence interval [CI], 1.32-2.02), whites with diabetes (HR, 1.15; 95% CI, 1.06-1.25), and Asians without diabetes (HR, 1.36; 95% CI, 1.14-1.64) had higher rates of the composite of death, myocardial infarction, or stroke at 30 days than whites without diabetes. Asians with diabetes (HR, 1.84; 95% CI, 1.47-2.31), whites with diabetes (HR, 1.47; 95% CI, 1.33-1.62), and Asians without diabetes (HR, 1.38; 95% CI, 1.11-1.73) had higher rates of death at 1 year compared with whites without diabetes. There were no significant interactions between race and diabetes for ischemic outcomes.CONCLUSIONS:Although Asians with diabetes and acute coronary syndrome are less likely to be obese than their white counterparts, their risk for death or recurrent ischemic events was not lower.

- Background: Regional differences in the profile and prognosis of non-ST-segment elevation acute coronary syndrome (NSTE ACS) patients treated with medical management after angiography remain uncertain.Methods and Results: Using data from the Early Glycoprotein IIb/IIIa Inhibition in Non-ST-Segment Elevation Acute Coronary Syndromes (EARLY ACS) trial, we examined regional variations in the use of an in-hospital medical management strategy in NSTE ACS patients who had significant coronary artery disease (CAD) identified during angiography, factors associated with the use of a medical management strategy, and 1-year mortality rates. Of 9406 patients, 8387 (89%) underwent angiography and had significant CAD; thereafter, 1766 (21%) were treated solely with a medical management strategy (range: 18% to 23% across 4 major geographic regions). Factors most strongly associated with a medical management strategy were negative baseline troponin values, prior coronary artery bypass grafting, lower baseline hemoglobin values, and greater number of diseased vessels; region was not a significant factor. One-year mortality was higher among patients treated with a medical management strategy compared with those who underwent revascularization (7.8% versus 3.6%; adjusted hazard ratio, 1.46; 95% CI, 1.21-1.76), with no significant interaction by region (interaction probability value=0.42).Conclusions: Approximately 20% of NSTE ACS patients with significant CAD in an international trial were treated solely with an in-hospital medical management strategy after early angiography, with no regional differences in factors associated with medical management or the risk of 1-year mortality. These findings have important implications for the conduct of future clinical trials, and highlight global similarities in the profile and prognosis of medically managed NSTE ACS patients.
