ABSTRACT
Background: Diabetes mellitus (DM) refers to a group of common metabolic disorders that share the phenotype of hyperglycaemia. India alone had 65.1 million diabetics by the year 2013. DM with high BMI & increased central obesity (WHR) have changes in the cardiac geometry evidenced in echocardiography. AIM OF STUDY: Estimation of Body Mass Index (BMI) and Waist Hip Ratio (WHR) & Establish a relationship between obesity, particularly central obesity in type 2 diabetes mellitus patients and cardiac changes with the help of echocardiography. Methods: 30 Subjects with type 2 DM attending the OPD or admitted in Katihar Medical College indoor department & 30 control patients were also be taken from the same, all of age >40 years. The cases and the controls were examined thoroughly with respect to BMI (>30) & WHR (> 0.85 for females and > 0.95 for males) and echocardiography was done. Results: The cases i.e. type 2 diabetes with high WHR and BMI had highly significant alteration in LV geometry as compared to the controls & had significantly high mean LV mass 189.10grams as compared to 134.04 grams of the controls. There was significant early diastolic dysfunction found in the cases group while no significant difference was found in systolic dysfunction between cases & controls. The incidence of changes in left ventricular geometry was higher in female type 2 diabetic subjects with high waist hip ratio and BMI as compared to males. Conclusions: Form the data of the present study it can be concluded that type 2 diabetics with obesity, particularly central type, have an increased predisposition to the development of left ventricular structural or geometrical abnormality. They have significantly higher left ventricular Mass. Obese type 2 diabetics also have higher incidence of diastolic dysfunction. All these abnormalities occur with greater frequency in females. Thus, type 2 diabetics with high BMI and Waist hip ratio have higher risk of development of cardiovascular disease, which is higher for female than males.
