Echocardiographic Characteristics
A total of 108 patients(50.7%) had abnormities on echocardiography. The
incidence of cardiac chamber enlargement, wall thickening, cardiac
disfunction and pericardial effusion in critical patients was
significantly higher than that in non-critical patients(p <0.05).
There were 22 (10.3%) patients with LVEF <50%. The critical
patients demonstrated lower median LVEF than non-critical
patients(p <0.01). There was no significant difference of the
maximum depth of pericardial effusion and tricuspid annular plane
systolic excursion(TAPSE)(p >0.05)between two groups. 26(12.2%)
patients have presented the signs of pulmonary hypertension and the
presence of pulmonary hypertension in critical group was higher than
that in non-critical group (p <0.001).(Table 2,Figure 1-3)
