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.
