Clinically non-severe COVID-19
In the non-severe intensity COVID-19 group, within which 41 patients were followed up, 4DLVEDVI significantly increased over time (39.9±8.7 cc/m2 vs. 44.6±1 cc/m2, p-value=0.02). In addition, 4DLVSVI (24.7±4.1 cc/m2 vs. 29.7±7.0 cc/m2, p-value<0.001) and LVEF (61.9% [59.8-64.5] vs. 63.8% [58.2-68.9], p-value=0.029) increased significantly. All the diastolic indices, including E and A wave velocity and lateral and septal E’ velocity, were in the normal range in both follow-up sessions. However, there was a significant change in lateral E wave velocity (14.7 m/s [12.7-16.7] vs. 13.2 m/s [12-16], p-value=0.006). The RV function indices were all in the normal range in both early and late echocardiograms. RVFWGLS significantly decreased in the late echocardiogram (-32.3±4.6% vs. -28.8±5.8%, p-value=0.002). RV-FAC (46.6% [43.6-53] vs. 39.7% [25-43], p-value<0.001) and TAPSE (21 mm [19-24] vs. 23 mm [20-25] , p-value=0.093) did not show a significant change. LA peak SR significantly decreased in the late follow-up (1.4% ±0.3 vs. 1.3% ±0.3, p-value<0.015). There was no significant difference in systolic PAP between the early and late echocardiograms. Other variables are described in detail in Table 2.
