Electrocardiographic abnormalities and troponin levels provide insight on the prognosis of COVID-۱۹ patients: A single center experience from Iran

Objective: Coronavirus disease ۲۰۱۹ (COVID-۱۹) is an infection which can present itself bythe involvement of various organs, but the most common manifestations are respiratorysymptoms, fever and dyspnea with a high mortality rate. In order to study the prognosis ofpatients and also to determine the treatment plan, we need non-invasive methods whichcan be easily used in the triage of patients. In this study, we investigated the diagnosticvalue of electrocardiographic (ECG) changes and troponin levels in patients with thisdisease.Methods: This is a descriptive study. Confirmed COVID-۱۹ patients participated in thepresent study. Data were collected by taking history and referring to medical records. Weanalyzed data by using chi square, t test and logistic regression through SPSS softwareversion ۲۲.Results: One hundred and five patients with COVID-۱۹ disease were examined. Mostpatients were men (۵۳.۳%) and the mean age was ۵۴.۵۳ years. The most common underlyingdiseases were hypertension and diabetes mellitus. Ninety-five patients had abnormalelectrocardiography including eleven with long QT; seven with arrhythmia; ۷۸ with sinustachycardia; ۷ with hemi-block; ۱ with hemi-block and first degree atrioventricular block;۴ with abnormal axis and ۲۸ with ischemic changes. Eleven patients (۱۰.۵%) had positivetroponin level, whose length of hospital stay was higher (۱۲.۷۳ vs. ۱۲.۰۷ days). Furthermore,their mean length of intensive care unit (ICU) stay was also higher. In addition, among thetroponin-positive group, ۱۰۰% had abnormal electrocardiography.Conclusion: The findings of the present study showed that ECG abnormalities and troponinlevels could provide good information about the prognosis of patients. Moreover, it seemsthat ECG changes in COVID-۱۹ patients, whether indicative of underlying heart disease orresulted from infection, can affect the prognosis of patients. Therefore, considering ECGfindings and troponin levels can help select patients at a higher risk for triage.
