a & b: Relationship between tissue phase mapping indices and conventional measures of cardiac function - a. Radial systolic myocardial velocity (S′) versus diastolic blood pressure (DBP) (rho = − 0.37, p < 0.0001), b. Radial systolic myocardial velocity (S′) versus ejection function (rho = 0.24, p = 0.009). The 95% confidence interval of the predicted mean is illustrated by the grey zone
