Pearson's correlation coefficients between echocardiographic variables, exercise test results, and health status scores

LVD-36 LIhFE
Exercise test (n=38)
 Achieved Vo 2(ml/min/kg)0.523-165 0.493-160
 Exercise duration (s)0.453-160 0.383-150
Echocardiogram (n=60)
 Left ventricle cavity in diastole (cm)0.12 (NS)0.08 (NS)
 Left ventricle cavity in systole (cm) 0.22 (NS)0.17 (NS)
 Systolic shortening fraction (%)−0.273-150 −0.22 (NS)
 Ejection fraction (%)−0.25 (NS)−0.22 (NS)
  • 3-150 p < 0.05;

  • 3-160 p < 0.01;

  • 3-165 p < 0.001.

  • Note: In technically difficult echocardiograms, no value was provided for ejection fraction. For this reason, only 46 of the 60 patients had ejection fraction measured using an echocardiogram.
