Screening for coronary artery disease in patients with type 2 diabetes mellitus: An evidence-based review

Coronary artery disease (CAD) is the leading cause of morbidity and mortality in patients with diabetes. CAD is often asymptomatic in these patients, until the onset of myocardial infarction or sudden cardiac death. Consequently, proper screening and diagnosis of CAD is crucial for the prevention and early treatment of coronary events. This review deals with selection of the sub group of patients who have type 2 diabetes, who are at high risk for developing CAD and need to be screened for the same. The various diagnostic modalities which can be used in the screening process for enhancing risk stratification and management are also discussed.
