Abstract

Background/aim: Increase in publications supporting myocardial involvement in the COVID-19 disease has led to need to gain insight into the the global burden of heart failure after pandemic. We examined the course of myocardial systolic function in patients without elevated troponin levels. Materials and methods: We performed a prospective study. Patients with high troponin levels were excluded from the study in order to definitively exclude complications known to cause permanent left ventricular systolic dysfunction, such as acute coronary syndromes. Two echocardiographic examinations were performed. The first evaluation was performed within the days of hospitalization, if possible, on the day when dyspnea is severe. The second evaluation was performed during the outpatient clinic controls one month after the patient was recovered. Left ventricular ejection fraction (LVEF) was measured using the biplane method of disks (modified Simpson's rule). Results: In the first evaluation, LVEF was found to be significantly lower in the severe illness group than mild/moderate illness group (50 ± 6% and 59 ± 6%; p = 0.03). LVEF decrease (
