Patients presented with functional damage involving multiple vital organs, including respiratory failure (80 [94.1%]), shock (69 [81.2%]), ARDS (63 [74.1%]) arrhythmia (51 [60.0%]), acute myocardial injury (38 [44.7%]), acute liver injury (30 [35.3%]) and sepsis (28 [32.9%]) (Table 5)

The final diagnosis was acute virus-negative lymphocytic myocarditis associated with SARS-CoV-2 respiratory infection

In addition, repeated floods of catecholamines due to anxiety and the side effects of medication can also lead to myocardial damage.

However, an elevation of high-sensitivity cardiac troponin I (cTnI) above 99th percentile upper reference limit is the most commonly used definition

Among the 68 fatal cases, 36 patients (53%) died of respiratory failure, five patients (7%) with myocardial damage died of circulatory failure, 22 patients (33%) died of both, and five remaining died of an unknown cause
