Patients with COVID-19 pneumonia
From a total of 25 patients who were prescribed to perform spiral chest CT-scan, 13 showed non-severe and severe COVID-19 pneumonia. On the late echocardiogram, LVSVI and LVEF showed significant rise (21.3±4.1 vs. 29.1±5.5, p-value=0.03 and 57.5 [53.3-64.4] vs. 64 [59.5-66.1], p-value=0.01, respectively) in comparison with the baseline echocardiogram. There was an increase, though not statistically significant, in LVGLS (-20.3% [-22.1- -18.8] vs. -23.2% [-24.3- -20.6], p-value=0.08) and LVGCS (-27.9% ±3.6 vs. -30.2% ±4.3, p-value=0.34) over the study time frame. Amongst RV echocardiographic indices, RVFAC and TAPSE showed a decrease which was not statistically significant (48.7 % [42.7-52] vs. 36.55 % [30.7-49.5], p-value=0.059 and 23 mm [21.5-25] vs. 22 mm [21-25], p-value=0.96, respectively). Also, none of the other indices changed significantly, including RVEDVI, RVESVI, RVEF, RVFAC, RVsm, and RV strain rate. Of LA parameters consisting of LA peak SR and LAESV, none showed a statistically significant change on the late echocardiogram. RA parameters, including systolic PAP and peak SR, did not demonstrate any significant change over the follow-up time. (Supplementary Table S2)
