Diabetes and Mortality Following Acute Coronary Syndromes

To evaluate the influence of diabetes on mortality following ACS using a large database spanning the full spectrum of ACS. DESIGN, SETTING, AND PATIENTS: A subgroup analysis of patients with diabetes enrolled in randomized clinical trials that evaluated ACS therapies. Patients with ACS in 11 independent Thrombolysis in Myocardial Infarction (TIMI) Study Group clinical trials from 1997 to 2006 were pooled, including 62,036 patients (46,577 with ST-segment elevation myocardial infarction [STEMI] and 15,459 with unstable angina/non-STEMI [UA/NSTEMI]), of whom 10 613 (17.1%) had diabetes. A multivariable model was constructed to adjust for baseline characteristics, aspects of ACS presentation, and treatments for the ACS event. MAIN OUTCOME MEASURES: Mortality at 30 days and 1 year following ACS among patients with diabetes vs patients without diabetes.

Mortality at 30 days was significantly higher among patients with diabetes than without diabetes presenting with UA/NSTEMI (2.1% vs 1.1%, P
