EDV, left ventricular end-diastolic volume; EF%, ejection fraction; ESV, left ventricular and systolic volume; FS%, fractional shortening; IVSd, interventricular septal thickness at end diastole; LVIDd, left ventricular internal diameter at end diastole; LVIDs, left ventricular internal diameter at end systole, LVPWd, left ventricular posterior wall at end diastole.

^*Correlation and regression values are significantly (p < 0.05) related to the echocardiographic parameter.

^**Correlation and regression values are highly significantly (p < 0.01) related to the echocardiographic parameter.

^***Correlation and regression values are extremely significantly (p < 0.001) related to the echocardiographic parameter.
