Assessment

Primary outcomes

To evaluate the correlations between myocardial velocity index (e'), flow propagation velocity (Vp), strain rate index (ESR) and time constant (tau) or LV filling pressure.

Key secondary outcomes

To compare the accuracy for estimating LV relaxation and filling pressure between the measuring methods of e', Vp, and ESR.
