- 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 Dose adjustment of renally excreted antithrombotic drugs is recommended for patients with reduced renal function. We examined the influence of dose modification on bleeding and efficacy. Methods Based on initial study drug infusion rate, Early GP IIb/IIIa Inhibition in non-ST-segment elevation acute coronary syndromes (EARLY ACS) patients were categorized into groups: standard dose (2 mu g/kg/min; estimated creatinine clearance [eCrCl] >= 50 ml/min), adjusted dose (1 mu g/kg/min; eCrCl <50 ml/min, per protocol), excess dose (2 mu g/kg/min; eCrCl <50 ml/min). We explored relationships among initial dosing, randomized treatment assignment, and bleeding and ischemic end points (96-h composite of death, myocardial infarction [MI], recurrent ischemia requiring urgent revascularization or thrombotic bailout, and 30-d death or MI). Results Of 8,708 patients with eCrCl and dosing data, 19% had eCrCl <50 ml/min. Of these, 13% received adjusted dose eptifibatide and 6% received an excess dose. Across all dosing groups, no significant reductions were found in ischemic end points between early versus delayed provisional eptifibatide (OR 1.14, 95% CI 0.80-1.65; OR 1.13, 95% CI 0.81-1.56, respectively, for 96-h and 30-d composite end points). Bleeding risk was not significantly increased in the early versus delayed provisional treatment group in either the adjusted (OR 1.50, 95% CI 0.95-2.39) or excess dose group (OR 1.67, 95% CI 0.85-3.39). There were no significant interactions between dose group and treatment strategy on bleeding or efficacy. Conclusion Similar to observations in practice, despite guidelines recommendations and protocol guidance, 34% of EARLY ACS patients with reduced renal function failed to receive an appropriately adjusted study drug infusion. Use of an appropriately adjusted eptifibatide infusion was not associated with expected reductions in bleeding among patients with renal insufficiency.
