It has been recognized for nearly a quarter of a century that patients with diabetes who develop cardiovascular disease (CVD) suffer from a worse prognosis than do CVD patients without diabetes mellitus.1 Against this background, the news from the CHARM Investigators2 that diabetes is an independent predictor of cardiovascular morbidity and mortality, not only in heart failure patients with severe systolic dysfunction but also in those with preserved ejection fraction, is not a big surprise. Accelerated coronary atherosclerosis,3 abnormal platelet function, coagulation, fibrinolysis, and endothelial dysfunction which favour coronary thrombosis,4 and autonomic neuropathy associated with an increased rate of ventricular arrhythmia and sudden death5 are possible mechanisms which may independently from left ventricular systolic dysfunction contribute to an increased risk of fatal and non-fatal complications in patients with diabetes and CVD.
Hence, the interesting and not easy to explain issue in the study of MacDonald
