Cardiac metabolism in diabetes mellitus.
Diabetes mellitus is one of the most common chronic illnesses throughout the world. Diabetic cardiomyopathy is a specific syndrome, consisting of cardiomegaly, left ventricular dysfunction, electrical remodeling of the ventricle, and symptoms of congestive heart failure, that is seen in diabetic patients in the absence of other predisposing factors. Many researchers have suggested that inhibition of the renin-angiotensin-aldosterone system and the sympathetic nervous system may exert a therapeutic effect in individuals with diabetic cardiomyopathy. Indeed, angiotensin II and aldosterone blockade may be effective, partly because aldosterone blockade down-regulates Na(+)/H(+) exchanger 1 activity. Further study of the alterations in ion channel physiology in the context of diabetic cardiomyocytes may be of benefit.
