Abstract

The increasing global burden, the reported high prevalence of rapidly progressive coronary artery disease (CAD), and the atypical nature of CAD presentation in type 2 diabetes mellitus have encouraged development of strategies for detecting occult CAD in this population. Several recent prospective studies have addressed the value of screening for CAD in asymptomatic diabetic patients. The overall message of these studies is that despite detection of silent ischemia in a notable proportion of these patients, the dynamic nature of myocardial ischemia, the prohibitive cost of screening all asymptomatic patients, and the proven efficacy of primary preventive strategies would mandate implementation of better clinical risk stratification strategies for identifying at-risk individuals. Questions still remain as to what best strategy would allow proper patient selection through logical stepwise approaches to screening and whether that would alter patients’ outcome when added to rigorously implemented primary preventive measures.
