ABSTRACT
COVID-19 has several clinical manifestations in the respiratory system and the cardiovascular system. Pneumothorax and myocardial infarction with nonobstructive coronary arteries (MINOCA) are two different clinical complications in COVID-19. However, pneumothorax and MINOCA have not been described yet in the same patient until now. A COVID-19 patient was admitted due to respiratory distress. He had pneumothorax and MINOCA. We report how we proceeded with diagnosis and treatment of pneumothorax and MINOCA. Respiratory and cardiovascular system manifestations of COVID-19 have made numerous clinical appearances. MINOCA and pneumothorax are rare clinical appearances, but they can be seen in COVID-19 as shown in our case. Copyright © 2022 Czech Society of Cardiology Z.S. All rights reserved.
ABSTRACT
Aims: fQRS-T angle was investigated from general population including healthy people to patients who has hearth failure. It can predict mortality of myocarditis, ischemic cardiomyopathy, non-ischemic cardiomyopathy, idiopathic dilated cardiomyopathy and chronic heart failure in general population. There is no study in the literature that has been investigated for COVID-19 patients. The purpose of this retrospective multi-center study is to evaluate fQRS angle of COVID-19 patients for in-hospital mortality and need mechanical ventilation. Methods and results: ECG was enrolled in 327 COVID-19 patients during admission and the fQRS angle calculated. Mechanical ventilation was needed for 119 patients and 110 of them died in hospital. Patients were divided into two groups according to their fQRS angle as fQRs>90° and fQRS≤90°. Percentages of mortality and need of MV according to fQRS angle were found 67.8% and 66.1% respectively in fQRs>90° group and 26.1%, 29.9% in fQRS≤90°group. Heart rate, SO2, fQRS, eGFR and CRP only were predictors for mortality in multivariable analysis. Mortality risk was increased 2.9-fold in univariate analysis and 1.6-fold in multivariate analysis for fQRS>90 patient group in respect to fQRS≤90 group. Conclusion: In conclusion, a wide fQRS angle (>90°) was found as a predictor for mortality in-hospital and associated with the need for mechanical ventilation in COVID-19 patients. (Figure Presented).
