Background: Diastolic dysfunction is one of the most widely documented cardiovascular issue. The present study was conducted to evaluate echocardiography in left ventricular diastolic dysfunction among diabetics. Materials & Methods:70 patients with diastolic dysfunction of both genders were selected. Echocardiography was performed with convextransducer. Grading of left ventricular systolic and left ventricular diastolic dysfunction was done. Blood investigation such as fasting and random blood sugar and glycated hemoglobin level was estimated to detect underlying diabetes. Results: Out of 70 patients, males were 40 and females were 35. Left ventricular systolic dysfunction (LVSD) was seen in 35 subjects, in which 11 were non- diabetic and 24 were diabetics. Grading found to be 0 seen in 0 and 4, 1 seen in 2 and 6, 2 seen in 4 and 8, 3 in 5 and 6 subjects with non- diabetes and diabetes respectively. Left ventricular diastolic dysfunction (LVDD) was found in 35 subjects. In LVDD, 19 were diabetics and 16 were non- diabetic. In LVDD, 19 were diabetics and 16 were non- diabetics. Grading in LVDD found to be 0 seen in 2 in non- diabetics, 1 seen in 6 and 6, 2 seen in 5 and 9, 3 in 3 and 4 subjects with non- diabetes and diabetes respectively. The difference was significant (P< 0.05).Conclusion: Authors found that diastolic dysfunction can be assessed with echocardiography. Diabetes mellitus had independent positive impact on left ventricular diastolic dysfunction.
