Different Grades of Body Mass Index are Correlated with Left Atrium and Ventricle Structures in Patients with Hypertensive Heart Disease

Obesity constitutes a major health issue which contributes as the risk factor of cardiovascular disease. This cross-sectional study included 50 consecutive patients with HHD (Hypertensive Heart Disease) in the Cardiovascular Department of Dr. Soetomo General Hospital. The echocardiographic examination was done using GE vivid 7. The statistics were evaluated using SPSS 25.0. The research showed that different grades of BMI (body mass index) were positively correlated with Left Atrial (LA) major (r=0.335), Right Atrial (RA) Major (r=0.371), Left Ventricle end Diastole (LVD) Mass (r=0.341), Left Ventricle end Sytole (LVS) Mass (r=0.303), Left Ventricle Posterior Wall end Diastole (LVPWD) (r=0.369), Left Ventricle Posterior end Systole (LVPWS) (r=0.391), and inversely correlated with Left Ventricle Sphericity Index (LVSI) Doppler (r=-0.376). Obese (BMI>30) patients have a significantly lower ejection fraction compared to normoweight (BMI<25) patients (64.3±3.67% vs 62.12±0.98%, p=0.046). In conclusion, the grade of BMI of the HHD patient is associated with an increased volume of the left atrium and ventricle. This suggests that obese patient with HHD should be assessed carefully for atrial and ventricle enlargement.
