title: Markers for silent myocardial ischemia in diabetes. Are they helpful?
abstract: Silent myocardial ischemia (SMI) and silent coronary stenoses (CS) are two to seven times more frequent in diabetic patients than in non-diabetic patients. In addition to this, they have a higher predictive value for cardiovascular events than the classical cardiovascular risk factors, either taken alone or combined. Coronary arterial disease is the leading cause of mortality and morbidity in the diabetic population. Altogether, these data suggest that screening for SMI and silent CS is an important issue. We assume that detecting SMI and silent CS improves patient management, and leads to optimised follow-up, action taken on nutrition, exercise and lifestyle, management of the cardiovascular risk factors, and revascularisation procedures whenever possible. However, screening for SMI and silent CS is expensive and may induce morbidity. Selecting the patients with a high a priori risk of SMI and silent CS is therefore of major concern. Carotid or lower limb peripheral arterial disease, proteinuria, male gender, an age greater than 60 years, and two or more cardiovascular risk factors among smoking, microalbuminuria, dyslipidemia, hypertension, a family history of premature cardiac disease, and cardiac autonomic neuropathy have been demonstrated to be the best current predictors of SMI and silent CS. New markers, such as adhesion molecules, Lp(a), inflammation parameters or homocysteine, and endothelium function assessment might be of further help in the future.
