The diameters of cardiac cavity and LVEF
The diameters of cardiac cavity and other echocardiographic parameters
are shown in Table 3. Patients with COVID-19 pneumonia had significantly
larger right atrium and right ventricle than healthy subjects (P
< 0.01), and there were no statistically significant
difference in RAD and RVD between severe and critically severe patients
(P > 0.05). Critically severe patients had a significantly
lower LVEF than healthy subjects and severe patients (P <
0.05).
