Genetic aspects of diabetes and its cardiovascular complications: contribution of genetics to risk assessment and clinical management.

Diabetes mellitus is a source of great concern in contemporary cardiology. It is a heterogeneous disease and patients are often characterized by features of the insulin resistance syndrome, also referred to as the metabolic syndrome. The objectives of the present review were to discuss some genes that potentially modulate the risk of coronary artery disease in diabetes mellitus; to address how the genes' respective contributions could possibly influence the global risk assessment of coronary artery disease among diabetic patients; and to present simple clinical markers, such as plasma glycerol concentration and the 'hypertriglyceridemic waist' phenotype, that could help to identify high-risk individuals.
