Mean age of diabetic patients was 57.17 years, Ratio of male to female was 1.17:1,As the age of diabetic patients increases, LV diastolic function decreases. Mean EF% was found lower in 60-75 years group (47.39%) as compared to 51.66%-of 40-49 years age group. Mean Ve/Va was found lower in 60-75 years group (0.84) as compared to 0.88 of 40-59 years age group. As BMI increases, LV diastolic dysfunction increases.
