Risk factors of adverse outcome
At the end of follow-up, all non-critical patients and 35 of 63 critical patients were discharged. 28 critical patients needed invasive mechanical ventilation, 16 of whom died during the hospitalization, and another 12 patients were transferred to Zhongnan Hospital of Wuhan University with tracheotomy. By multivariate logistic regression, we found that hs-cTnI elevation (OR 6.069, 95%CI 2.358-15.615;p =0.000) and echocardiographic signs of pulmonary hypertension of pulmonary hypertension (OR 3.635, 95%CI 1.257-10.509; p =0.017) may be the independent risk factors of adverse outcome.
