Objectives: To assess the role of essential organ-based comorbidities in the prognosis of COVID-19 patients.
Methods: All consecutive patients diagnosed with COVID-19 admitted to the Zhongnan Hospital of Wuhan University from 11 January to 16 March 2020 were enrolled in this retrospective cohort study.
Results: A total of 212 COVID-19 patients were included. COVID-19 patients with heart, liver and kidneycomorbidity, compared to patients without related comorbidities, were more likely to have cardiac injuries [9.1%(3/33) vs 2.2%(4/179), P = 0.043], liver injuries [13.0%(3/23) vs 3.2%(6/189), P = 0.027], kidney injury [54.5%(6/11) vs 2.0%(4/201), P < 0.001], and higher risk of mortality [Heart-comorbidity: 6.1%(2/33) vs 0.6%(1/179), P = 0.014; Liver-comorbidity: 8.7%(2/23) vs 0.5%(1/189), P = 0.002; Kidney-comorbidity: 27.3%(3/11) vs 1.0%(2/201), P < 0.001. Mortality was higher in patients with more severe Grade of organ injuries [Heart-injury: P = 0.044; Liver-injury: P = 0.020; Kidney-injury: P = 0.030].
Conclusion: Male, older, co-existing of heart, liver, and kidney comorbidities, especially those with severe Grade organ injuries, had a poor prognosis after SARS-CoV-2 infection.
