title: Heart failure and diabetes.
abstract: Diabetes substantially increases the risk of heart failure both in men and women, being included in the Stage A classification of heart failure by the American Societies of Cardiology. The main etiological factors contributing to heart failure in diabetes are coronary artery disease, systemic hypertension and diabetic cardiomyopathy, the latter being invoked in case of heart failure where the first two factors are missing. Renal insufficiency and obesity may also play a role. The diagnosis will follow the same steps as in non-diabetic subjects: careful and periodic assessment for signs and symptoms of heart failure in all diabetic patients, echocardiography to assess the systolic and diastolic function of the left ventricle, and B-type natriuretic peptide level (as a marker of left ventricular dysfunction). The therapeutic approach will include non-pharmacological measures and pharmacological treatment. Patients with diabetes and heart failure benefit of the same drugs as non-diabetic subjects, including beta-blockers, which should not be avoided in patients with diabetes. The antihyperglycemic agents that should not be used in patients with heart failure are biguanides and thiazolidindiones (pioglitazone can be used in NYHA I and II classes). Approaches that were proven to reduce the risk of heart failure in diabetes are blood pressure and lipid control, treatment with ACE inhibitors in patients with diabetes and other cardiovascular risk factors and improvement of the glycemic control.
