Table 2.
p values of comparing displacement, velocity, strain and strain rates between PH-HFpEF group (n = 19) and PH-HFrEF group (n = 9). PH-HFpEF patients has higher peaks of multiple LV displacement, velocity, strain and strain rate in systolic, early and late diastole than that of PH-HFrEF patients. P values < 0.05 were highlighted.
