Baseline clinical characteristics
213 patients diagnosed with COVID-19 were included in the final analysis,including 150 non-critical patients and 63 critical patients. Of 213 patients,110 (51.6%) were male. The median (IQR) age was 63.0(56.0-73.0). The median age of critical group was significantly higher than that of non-critical group (77.0 vs 63.0 years, respectively; p <0.001). There was significant difference in sex between two groups (p <0.01) and most of critical patients were male. Hypertension (52.6%),cardiac disease (21.6%),diabetes (19.2%) were the three most common comorbidities. The presence of cardiac disease, cerebrovascular disease and chronic kidney disease in critical group was all higher than that in non-critical group (p <0.05). The incidence of cardiovascular complications including acute myocardial injury, arrhythmia and acute myocardial infarction was higher in critical group than non-critical group. 5 of 63 critical patients developed acute myocardial infarction.
