Cardiologic scoring system as predictors of mortality in geriatric COVID-19 patients

Abstract

Objective: To develop a cardiologic scoring system to predict mortality among geriatric coronavirus disease-2019patients.Method: The retrospective cohort study was conducted after approval from the ethics review committee of the DrSoetomo General Academic Hospital, Surabaya, Indonesia, and comprised data from March 1, 2020, to April 30,2021, of geriatric patients of either gender confirmed for coronavirus disease-2019 from several referral hospitals inEast Java, Indonesia. Data on comorbidities, electrocardiograph, and chest X-ray findings was examined to developa comprehensive scoring system. Data was analysed using SPSS 26.Results: Of the 3,893 cases reviewed, data of 322(8.27%) patients was analysed; 191(59.3%) males and 131(40.7%)females. The overall mean age was 66±4.1 years (range: 60-75 years). Of them, 267(82.9%) subjects were alive uponhospital discharge, while 55(17.1%) died during hospitalisation. Of the 24 variables analysed, 5(21%) were found tobe significant: cardiomegaly, sinus tachycardia, ST-segment abnormalities, pathological T-wave inversions, and axisdeviation (p<0.05). Receiver operating characteristic curve analysis showed an area under the curve 0.86, cut-offpoint Less Than or Equal 4 with sensitivity 89% and specificity 69%.Conclusion: The scoring system was found to have the potential to predict mortality in geriatric coronavirusdisease-2019 patients based on cardiac findings during hospital admission.Key Words: Cardiovascular, COVID-19, Electrocardiography, Arrhythmia, Cardiomegaly, Tachycardia.
