P < .05 compared with the control group;
#
P < .05 compared with patients with a good prognosis. Data presentation: frequency (%). When the data were not in the normal distribution, they were presented as a median (interquartile range). Heart failure here indicates the newly appeared heart failure which occurred after admission.
