ABSTRACT
Background:
Exercise intolerance de novo is one of the most common reported symptoms in patients (pts) recovering from COVID-19. Purpose(s) The present study determines etiological and pathophysiological factors influencing the mechanism of exercise intolerance in the COVID-19 survivors. Therefore, the factors affecting percent predicted oxygen uptake at peak exercise VO2 (%VO2pred) in pts after COVID-19 with normal left ventricular ejection fraction were assessed. Methods andResults:
The 120 consecutive patients from the Department of Cardiology recovering from COVID-19 at three to six months after confirmed diagnosis were included. The clinical examinations, laboratory test results, echocardiography using Vivid E95 - GE Healthcare, non-invasive body mass analysis using Body Composition Analyzer (Tanita Pro), and spiroergometry using The MetaSoft Studio application were analysed. The subjects were divided into the two following groups Study i.e. pts with worse oxygen uptake (%VO2pred <80%;N=47) and control including these cases with %VO2pred >=80% (N=73) - Table 1. Pts with %VO2pred <80% presented significantly lower global peak systolic strain (GLPS) [p=0.03], tricuspid annular plane systolic excursion (TAPSE) [p=0.002] and late diastolic filling velocity (A) [p=0.004] compared to controls - Figure 1. The male gender (p=0.007) and the percent of total body water content (TBW %) (p=0.02) were significantly higher in study in comparison to the control group. The results of multiple logistic regression model independently associated with %VO2pred were as follows A (OR 0.4, 95% CI 0.17-0.95;p=0.03) and gender (OR 2.52, 95% CI 1.07-5.91;p=0.03). Conclusion(s) Males have over twice risk of persistent limited exercise tolerance after COVID-19 infection than females. The lower late diastolic filling velocity, tricuspid annular plane systolic excursion, worse global peak systolic strain, and hydration status are connected with limited exercise tolerance after COVID-19 in patients with normal left ventricular ejection fraction.
