Type 2 diabetes and coronary artery disease: Preserved ejection fraction and sudden cardiac death

摘要

BackgroundPrevious studies have shown that type 2 diabetes (DM2) is associated with sudden cardiac death (SCD) risk in post–myocardial infarction patients. The treatment of coronary artery disease (CAD) as well as DM2 has changed over time. ObjectiveThe purpose of this study was to compare the incidence of SCD in DM2 and nondiabetic patients with CAD and preserved ejection fraction (EF) in a prospective observational study (ARTEMIS study). MethodsIn 834 DM2 patients and 1112 nondiabetic patients with CAD enrolled, the EF measured ≥3 months after qualifying was 63% ± 10% in DM2 patients and 65% ± 8% in nondiabetic patients (P?
