2 D echocardiogram, Cardiomyopathy, Diabetes, Diastolic dysfunction, HbA1c, Insulin resistance


Background: Diastolic heart failure occurs due to impaired myocardial relaxation and compliance. Of late, it has been suggested that the changes in the diastolic function occurs before the onset of diabetes, and present in the prediabetic patients. It is also said to be associated with insulin resistance.

Methods: This observational study was performed on 50 diabetic patients, with asymptomatic type 2 diabetes. who came in for 2 D echocardiogram with suspected diastolic dysfunction.

Results: The mean age among the 50 patients in the study was 54.1±10.99 years and in controls it was 49.56±10.63 years. The fasting sugar among the patients was 179.43±41.57 mg/dl and the post prandial was 236.72±76.24, and it was in the normal range in the controls. The HbA1c was 9.93±1.2 among the patients and 6.09 ± 0.34 in the controls. In the patients, the E/A ratio was 0.83±0.09 compared to 1.22±0.31 of the controls, which was highly significant as the E/e ratio which was 15.1±3.4 and 7.3±0.08 respectively.

Conclusions: There was a higher prevalence of diastolic dysfunction among the patients with diabetes in our study. There was no relation of age or gender among the diabetic and the controls, while a strong association and indicators seem to be FBS, PLBS and HbA1c.
