Background: Diabetes mellitus (DM) is on the increase globally. Cardiovascular complications, such as left ventricular dysfunction is a major cause of death in patients with type II DM. Prior to the development of symptomatic heart failure, subclinical left ventricular dysfunction (systolic and diastolic) may exist for some time. Aim of this study is to find out abnormalities in left ventricular function in patients of type 2 diabetes mellitus with help of 2D Colour Doppler Echocardiography. To find its correlation with glycemic control on the basis of glycosylated haemoglobin (Hba1c).Methods: Total 100 Patients of type 2 Diabetes Mellitus of duration more than 10 years of both sexes were included in the cross-sectional study conducted from Jan 2018 to Aug 2019.All the patients were assessed through clinical examination and 2-D echocardiography and control of diabetes determined on the basis of HbA1c.Results: Study consisted of 100 patients with type 2 DM, 55(55%) were females and 45(45%) males. Majority of patients were in the age group of 4th to 6th decade of life. Diastolic dysfunction was present in 81(81%) patients. systolic dysfunction was present in 14(14%) patients. There was a linear increase in prevalence of diastolic dysfunction with increasing age, increased FPG, increased BMI. There was also significant correlation between LV diastolic dysfunction (LVDD) and LA size. While no statistical correlation found between gender, duration of diabetes, HbA1c with diastolic and systolic dysfunction.Conclusions: LV diastolic dysfunction is an early manifestation of diabetic cardiomyopathy. LVDD contributes significantly to morbidity of congestive heart failure in diabetic patients. Echocardiography is a very useful non-invasive tool in detecting LVDD and systolic dysfunction in type 2 DM patients.
