摘要

in recent decades there has been a gradual reduction in the morbidity attributable to ischemic heart disease as a consequence of smoking cessation, better recognition and treatment of hypertension, and the introduction of effective cholesterol-lowering drugs. Unfortunately, the rising global prevalence of Type 2 diabetes mellitus threatens to reverse these gains. Diabetes both accelerates the development of ischemic heart disease and adversely affects the prognosis of patients with established disease (9). A particular concern is that, in the setting of myocardial ischemia, diabetes increases the risk of developing cardiac contractile dysfunction and congestive heart failure (6, 11). Because effective cardiac contraction requires minute-to-minute production and consumption of large amounts of energy, this observation suggests that diabetes may perturb myocardial energy metabolism in ways that affect ischemic tolerance and/or mechanical efficiency
