Cardiovascular disease in patients with diabetes: clinical considerations.
Cardiovascular disease is the major cause of morbidity and mortality in patients with diabetes. Diabetic individuals have a 200% to 400% greater risk for vascular disease than nondiabetics, with a disproportionately greater burden of disease complications in non-white minorities. Although the atherosclerotic plaques in the two groups are similar, diabetics have more severe and more diffuse disease than nondiabetics. Recent advances in the treatment of coronary disease have improved survival for diabetics and nondiabetics, but diabetics still have double the case fatality rate as nondiabetics, and diabetic women have particularly poor outcomes. Diabetic individuals also have an increased frequency of silent ischemia, systolic and diastolic left ventricular dysfunction, and cardiac autonomic neuropathy. The high frequency of modifiable risk factors provides great opportunities for prevention, the cornerstones of therapy being glycemic control, aggressive risk factor modification, and ongoing patient surveillance and monitoring to facilitate early disease detection and prompt intervention. In patients with coronary disease who require revascularization, both mechanical coronary interventions and bypass surgery are effective therapies. Patients with multivessel coronary disease have better results following bypass surgery with arterial grafts than following coronary interventions. However, diabetic patients are at increased risk for poor long-term outcome following either revascularization modality, with high rates of restenosis following mechanical interventions and the development of atherosclerosis in conduits following bypass surgery.
