Optimal care of cardiovascular disease and type 2 diabetes patients: shared responsibilities between the cardiologist and diabetologist.
Type 2 diabetes and cardiovascular disease are inextricably linked. Patients with type 2 diabetes are at increased risk of cardiovascular events and mortality. However, controlling blood glucose, which until recently had often been the focus of the diabetologist, is only one component of optimal cardiovascular risk reduction. Vascular protection of the patient with diabetes also includes management of hypertension and dyslipidaemia and lifestyle changes such as smoking cessation. Now both cardiologists and diabetologists need to optimise all components of vascular protection, including glycaemic control, in patients with diabetes. An elevated blood glucose is predictive of poor outcomes in patients with acute coronary syndromes, even if frank diabetes is not present. Early control of hyperglycaemia should be achieved: a strategy that results in improved outcomes. More than two-thirds of patients with coronary artery disease (CAD) have abnormal glucose regulation, which is a predictor of poor outcome. Therefore, the presence of diabetes (and/or glucose intolerance) should be routinely screened for in cardiac patients on admission to hospital. Early identification and treatment of CAD in patients with diabetes is important for optimal prevention of cardiovascular events. However, screening all diabetes patients for CAD is not feasible, and selection of patients for non-invasive cardiac testing remains a challenge for both the diabetologist and cardiologist. Optimal care of diabetic and cardiac patients requires a multidisciplinary team approach, with key roles for the cardiologist and diabetologist.
