ReviewIs type 2 diabetes really a coronary heart disease risk equivalent?

The concept of diabetes as a coronary heart risk (CHD) equivalent postulates that patients with diabetes who do not yet have CHD are at an equally high cardiovascular risk as non-diabetic patients with CHD. This implies important therapeutic, psychological, and economical consequences. However, whereas several reports support the concept of diabetes as a CHD risk equivalent, others refute it, and several investigations find that the cardiovascular risk conferred by diabetes is strongly modulated by sex (with diabetes conferring a greater risk increase in women), diabetes duration, concomitant risk factors, or the presence of subclinical atherosclerosis. A detailed review of the literature shows that the concept of diabetes as a CHD risk equivalent is overly simplistic, because not all patients with diabetes are at the same cardiovascular risk. An individualized approach to cardiovascular risk estimation and management appears mandatory in patients with diabetes.
