Modulation of Cardiac Injury by ACE inhibitor/ARB in Patients with Severe COVID-19


 Introduction: Cardiac injury occurs in 7-22% of patient hospitalized with COVID-19 and an elevation in troponin is associated with a 4.2-fold increase in the risk of mortality. Preliminary data showed ACEi/ARB usage might not increase mortaily in COVID-19 patients. However, it is unknown if cardiac injury in patients with severe COVID-19 can be modulated by ACEi/ARB usage during evolution of the cardiac injury.Methods: In 154 COVID-19 patients with cardiac injury, the effect of ACEi/ARB treatment (17 patients) was compared with 137 patients without ACEi/ARB treatment. Cardiac injury was indicated by cTnI level.Results: In ACEi/ARB treatment group and no ACEi/ARB treatment group, peak cTnI level did not show significant difference (150.5 pg/ml [31.75-1179], vs 207 pg/ml [54.65-989.4], respectively, P = 0.21). Evolution of Cardiac injury (temporal change of cTnI at day 6, 9, 12, 15, 18, 21, 24, 27, 30, and 33) showed no statistical difference. Mortality (ACEi/ARB group vs no ACEi/ARB group; 52.9% vs 69.9%, P = 0.17), atrial arrhythmias (11.7% vs 24.4%, P = 0.36), requirement for invasive ventilatory support (29.4% vs 48.2%, P = 0.14) also showed no significant difference in two groups.Conclusions: ACEi/ARB usage during the COVID-19 was not associated with exacerbation of cardiac injury. These data should be interpreted as essentially hypothesis-generating due to small sample size.Clinical Trial Registration: This retrospective study was registered in Chinese clinical trial registry (ChiCTR 2000031301).
