Background: Diabetes mellitus is one of the most common diseases. Left ventricular diastolic dysfunction may represent the early stage of diabetic cardiomyopathy thus reinforcing the importance of the early examination of diastolic function in individuals with diabetes.Methods: This is a hospital based cross-sectional study done at a tertiary care hospital catering mainly to rural population. Patients having type 2 diabetes mellitus were scrutinized for doppler echocardiography and HbA1c levels. As per the previous studies and considering the prevalence of asymptomatic diastolic dysfunction in diabetics, the sample size was calculated. Statistical analysis was done by using descriptive and inferential statistics using chi square test.Results: In the present study 45 patients had HbA1C between 6.5- 8.0, out of which 9 had type I diastolic dysfunction, 1 had type II diastolic dysfunction and 35 had no diastolic dysfunction. 16 patients had HbA1C between 8.1- 9.5, out of which 7 had type I diastolic dysfunction, 8 had type II diastolic dysfunction and 1 had no diastolic dysfunction. 14 patients had HbA1C more than 9.5, out of which 4 had type I diastolic dysfunction, 5 had type II diastolic dysfunction, 4 had type III diastolic dysfunction and 1 patient did not had any diastolic dysfunction. The Chi-Square value is 55.51 and p value is 0.000 (Significant).Conclusions: Diastolic dysfunction correlates with the levels of glycosylated hemoglobin, duration of diabetes mellitus, presence of microvascular complications like diabetic retinopathy, neuropathy and nephropathy.
