Inflammation and Diabetic Cardiomyopathy

Abstract

Diabetes mellitus (DM) is a metabolic syndrome that manifests a low grade of systemic inflammation that contributes to the development of cardiovascular diseases (CVDs). DM is a predominant risk factor for CVDs inducing structural changes in the heart, infiltration of fibrosis, apoptosis, and cardiac remodeling, all leading to myocardial infarction (MI), heart failure (HF), and sudden cardiac death. Furthermore, more than 80% of diabetic patients usually die from heart diseases or diabetic cardiomyopathy (DCM). Currently, HF is one of the main causes of mortality in the world despite advances in drug treatments. According to literature, a strong association exists between chronic inflammation and the development of DCM. In order to have a better appreciation of the effect of diabetes and inflammation on the cardiovascular system (CVS), it is of paramount importance to have a better understanding of diabetes, the physiology of the CVS, and the pathophysiology of DM. Thus, the present review highlights the role of chronic inflammation in the complex interplay between the development of DM and DCM. Our understanding of the process is critical in the discovery of new targeted therapies for DCM and other forms of HF.
