BackgroundPatients with COVID-19 can develop myocardial injury and arrhythmia during the course of their illness. However, the underlying risk factors for the development of cardiovascular related manifestations are unclear. MethodsUsing a register-based multi-center cross-sectional design, we analyzed 80 patients with myocardial injury and 401 controls, as well as 71 patients with arrhythmia and 409 controls, all admitted with COVID-19. Putative risk factors for myocardial injury and arrhythmia were evaluated with logistic regression with adjustment for potential confounders. ResultsCOVID-19 patients with myocardial injury had fatigue (66.2%) and dyspnea (63.7%), while those with arrhythmia had dyspnea (71.8%). Patients with myocardial injury and arrhythmia had a significant mortality of 92.5% and 94.4%, respectively. A history of chronic obstructive pulmonary disease (COPD) or heart diseases was associated with an increased risk of myocardial injury (odds ratio [OR] = 1.94, 95% confidence interval [CI]: 1.01-3.71; OR = 7.43, 95% CI: 3.99-13.83) and arrhythmia (OR = 1.94, 95% CI: 1.00-3.75; OR = 13.16, 95% CI: 6.75-25.68). In addition, we found that gamma glutamyltranspeptidase (GGT) >50U/L (OR = 2.14, 95% CI: 1.37-3.32; OR = 1.85, 95% CI: 1.19-2.85), serum creatinine >111mol/L (OR = 8.96, 95% CI: 4.4-18.23; OR = 3.71, 95% CI: 2.01-6.85), serum sodium <136 mmol/L (OR = 4.68, 95% CI: 2.46-8.91; OR = 2.06; 95% CI: 1.06-4.00) were all associated with increased risk of myocardial injury and arrhythmia, respectively. ConclusionOur reported clinical characteristics and identified risk factors are important for clinical study of COVID-19 patients developing myocardial injury and arrhythmia.
