The aim of this study was to assess the role of left ventricular dysfunction and hypertrophy by various diagnostic modalities in normotensive type 2 diabetes mellitus patients. The burden of cardiovascular disease related to diabetes mellitus has been increasing multifold day by day. Diabetes mellitus formerly thought of as a problem of glucose metabolism, actually produces most of its harm by effect on the cardiovascular system. This is a Prospective and Observational Study. The selection of the 50 type 2 diabetes mellitus patients was done from either inpatients admitted for control of diabetes or out patients. 50 controls for the study were chosen from volunteering staff members and patients attenders. Patients with diabetes shows an significant increase in the left ventricular internal dimension, left ventricular mass, left ventricular wall thickness and diastolic dysfunction as compared to non diabetes. We conclude that earliest detection of preclinical left ventricular abnormalities like dysfunction in both systole and diastole and then to take preventive steps in order to arrest of halt the progress of the disease.
