Abstract
Cardiovascular disease is the major cause of morbidity and mortality in people with Type 2 diabetes, and risk of atherosclerotic disease is markedly increased in people with diabetes compared to people with normal glucose tolerance. The excess risk can not be completely explained by increased prevalence of other cardiovascular disease risk factors such as hypertension and hyperlipidaemia in people with diabetes. This review examines the role of hyperglycemia and glycemic control in cardiovascular disease in people with Type 2 diabetes. The results of prospective observational studies and randomized controlled trials are summarized. We conclude that control of hypertension and hyperlipidemia are important to reduce risk of cardiovascular disease in people with diabetes and may be more easily achieved than tight glycemic control.
