Objective: Left Ventricular diastolic dysfunction (LVDD) is an asymptomatic disease linked to eventual heart failure. Obesity and overweight are not known to be independently linked to LVDD. The objective is to adjudicate whether increased body size has an independent influence on LVDD. Study design and sample: For this study, a total of 495 subjects were selected. LV diastolic function was estimated using both traditional and tissue-Doppler imaging. Peak early and late trans-mitral diastolic flow velocities (E, A) and early diastolic mitral annulus velocity (E′) were utilized to calculate E/A and E/E′. The individuals were categorised into three groups: overweight (BMI 25.0–29.9), normal weight (BMI 25.0), and obesity (BMI 30)
