Clinical and Echocardiographic Indices according to body mass
index are depicted in Table IV
Twenty three percent of participants were overweight and 44% were
obese. Obese participants had higher heart rate than non-obese
participants (p=0.002) There were no statistically significant
differences with regard to RA volumetric measurements, but RALS had a
tendency to decrease with increasing BMI (35.7 ± 9.3%, <25
kg/m2; 34.6 ± 11.4, <30
kg/m2 ; and 29.9 ± 10.1, >30
kg/m2 respectively, P=0.571). RV E′ / A’ ratio
decreased with increasing BMI (P=0.020) suggestive of worsening RV
diastolic dysfunction with increasing BMI. LA volume and size increased
with an increasing BMI (P= 0.010 and P <0.001, respectively).
Similar to RV diastolic parameters there was worsening of LV diastolic
function with an increase in BMI.
