ABSTRACT
Background:
Patients with coronavirus disease 2019 (COVID-19) can develop cardiac injury resulting in cardiac arrhythmias, myocarditis, and acute coronary syndrome (ACS). In this study, we aimed to investigate whether COVID-19 infection affects ventricular repolarization parameters such as Tpeak-Tend interval (Tp-e), QT interval, corrected QT (QTc), Tp-e/QT, and Tp-e/cQT in patients with ACS.Methods:
The study consisted of two groups. The first group included patients with ACS and COVID-19 (Group 1) (n = 50). Polymerase chain reaction test positive patients were enrolled. The second group included patients with only ACS (Group 2) (n = 100). The risk of ventricular arrhythmias was evaluated on the basis of the measured electrocardiographic Tp-e and QT interval, and QTc, Tp-e/QT, and Tp-e/QTc values.Results:
Tp-e interval, QTc, and Tp-e/QTc were significantly higher in the group1 than group 2 (p < .001, p < .018, and p < .001, respectively). Significant positive correlations were found between Tp-e, D-dimer level, and C-reactive protein (CRP) level in the group1 (p = .002, p = 0 .03, and p = .021, respectively). Univariate and multivariate regression analyses revealed that Tp-e was one of the independent predictor of length of stay in the intensive care unit (ICU). (B = 1.662, p = .006 and B = 1.804, p = .021, respectively).Conclusions:
In the patients with ACS, COVID-19 infection caused increases in QTc, Tp-e, and Tp-e/QTc ratio. In addition, age and prolonged Tp-e were found to be independent predictors of prolonged ICU stay.
