Relation between Body Mass Index, Waist Circumference, and Echocardiographic Index of Left Ventricular Diastolic Function

weight, blood test, personal habits questionnaire, and echocardiographic indices were obtained. We analyzed the echocardiographic indices of left ventricular diastolic function with BMI and WC. Results: The left ventricle (LV) mass index (P = 0.007), LV dimension (P < 0.01), A (P < 0.01), Aʹ (P = 0.030), and E/Eʹ (P = 0.006) were higher, and E (P = 0.003), Eʹ (P < 0.01), E/A (P < 0.01) were lower in the overweight and obese groups than in the normal group. On multiple linear regression analysis, E/Eʹ correlated positively with age, gender, BMI and systolic blood pressure. In men, E/Eʹ correlated positively with age and BMI or WC. In women, only age had a positive correlation with E/Eʹ. Conclusion: In men, increased BMI or waist circumference are associated with an increase in E/Eʹ, which surrogates left ventricular diastolic dysfunction. In women, obesity and abdominal obesity have no correlation with E/Eʹ.
