[Cardiovascular impact of the autonomic neuropathy of diabetes mellitus]

Abstract

The neuropathic complications related to Diabetes may affect the somatic, sympathetic and parasympathetic nervous system. As a result, there are several clinical manifestations of diabetic neuropathy. They can be related to nervous system lesions of the genital, urinary, gastro-intestinal, skin and cardiovascular tissues. The results of these alterations are loss in the quality of life as well as increase of mortality indexes related to sudden death with cardiac arrhythmias and other causes. The cardiovascular autonomic neuropathy probably contributes to the bad prognosis of the coronary heart disease and of the heart failure in type 1 and type 2 diabetic patients. For diabetologists, the nervous complications of diabetes are the result of an increase influx of glucose to the neuronal and endothelial cells. Evidences show that, with the aim of preventing these complications, the diabetic patients should receive a precocious diagnosis and be instructed for having a good metabolic and blood pressure control. Use of angiotensin converting enzyme inhibitors and beta adrenergic blockers are probably of impact in the prevention of the cardiac autonomic complications of diabetes.
