ABSTRACT
Limited evidence exists regarding adverse effects on cardiovascular and pulmonary function in adults affected by covid 19 infection. We describe the cardiopulmonary functions in a cohort of national level athletes with recent covid infection. 42 healthy athletes were evaluated after at least a 10-day period of quarantine after mild covid infection.44% females [n=19] and 56% males [n=23]. The age range was 15 - 38 years. The commonest persistent symptoms were difficulty in breathing (4.8%), cough (7%) and chest tightness (4.8%). PCFS (post covid functional score) was 0 in 93%. The CXR and 6-minute walk test were normal in all. The spirometry was normal in 83% (n=35). The mean FEV1 were 2.68l and 3.75l;mean FVC were 3.09l and 4.6l in females and males respectively. The mid expiratory flow rate (FEF 25-75) was less than the predicted lower limit of normal in 52.4%(mean=2.8L). Cardiac abnormalities were detected in 7%;moderate interventricular septal dyssynchrony, global hypokinesia with mild LV dysfunction and mild pulmonary hypertension. 13 players with persistent difficulty in breathing and chest tightness who had otherwise normal spirometry and echo were referred for CPET. Only 6 players had CPET due to limited resources: evidence of deconditioning (n=3) and cardiac limitation with poor O2 pulse (n=3). 78% (n=33) had normal cardiopulmonary assessment and were referred for graduated return to practice. Abnormalities were identified in 21% (n=9). Mid expiratory flow was reduced in 53% indicating possible effect on peripheral airways post covid. Evaluation of athletes and guidelines on return to practice after covid infection are an important and timely need.
