Mitral annular peak systolic and diastolic velocities are characteristic of healthy hearts: A Doppler tissue imaging study.

In a cohort of subjects with varying levels of combined systolic and diastolic function, the easily obtainable composite score of S' + E' ≥ 20 cm/s is strongly predictive of normal global left ventricular function with a high degree of sensitivity and specificity. Additional studies should be considered to expand this concept to additional populations.
