Core Tip

Core Tip: Recent evidence has linked cardio-cerebrovascular events in type 2 diabetes mellitus patients with concurrent coronary artery disease to blood glucose (BG) fluctuation, and the greater the BG fluctuation, the higher the incidence of chronic vascular complications of diabetes mellitus and acute cardiovascular events, and the worse the prognosis. This study analyzes how BG variability impacts heart rate dynamics in such patients and the predictive properties of functional myocardial ischemia.
