Abstract

Abstract Background: This study was conducted to evaluate left ventricular dysfunction in diabetics and to find correlation with glycemic control and biochemical parameters compared to non-diabetic population. Methods: Thirty type 2 diabetics and thirty nondiabetic controls were recruited. Age, sex, body mass index of the controls were matched. Results: Mean duration of diabetes mellitus in study population was 10.97± 4.01years. Among study population both cases and controls had ejection fraction >55%( no systolic dysfunction). Among cases(n=16) 53.3% were having mean E/A ratio <1 and(n=14) 46.67% were had mean E/A ratio >1. In controls all of them had mean E/A ratio above 1. This difference of mean E/A ratio among cases and controls was statistically significant (p<0.001). Among patients with diabetes, 9.09% cases with a HbA1cbetween 6-7%, 33.33% between 7.1-8%, respectively 100% of cases with HbA1c>8.1% had diastolic dysfunction the differences between groups being statistically significant (p<0.001). Low density lipoprotein( LDL) was weakly and negative correlated with E/A ratio (r = - 0.38) while fasting blood sugar (r = -0.53) respectively Hemoglobin A1c (r = -0.66) were moderately and negatively correlated. All these correlations were statistically significant. Conclusion: Subclinical diastolic dysfunction is prevalent among diabetic population. Diastolic dysfunction in patients with diabetes was correlated with FBS, HbA1C and LDL.
