Cardiovascular complication of diabetes (CCD) is a leading cause of mortality in diabetic patients, and diabetic cardiomyopathy(DC) vastly accounts for heart failure in those CCD patients. In the research of pathogenesis, early diagnosis and better treatment of DC, cardiac function evaluation plays a key bridging role. Addtionally, animal models may well simulate the development of diabetes. The purpose of this article is to review the important methods in evaluating heart function of diabetes animal models.
