What Is Diabetic Cardiomiopathy: Pathophysiologiy andClinical Spectrum

Diabetic cardimomyopathy is a distinct clinical entity despeed as thee presence of myocardial dysfunction in patients with diabetets colletitus in thee absence of coronary artery disease, hypertension, or valvular heart disease.

At the cellular level, hyperglycemia induces excessive production of reactive oksygen species, activation of protein kinase C isoforms, and accumulation of advanced excession end- products (AGEs).

Altered Substrate Metabolism and Insulin Resistance

Thyroid measures directly regulate lipid and glucose metabolizm. Thyroidism enhances lipolysis and increases romeating free fatty acids, which can worsen insulin resistance in diabetic patients. The shift to ward fatty acid oksydation in thee heart, combinad with with difficired glucose utilization, reduces cardigac efficiency and promotes lipoxixity.
