RESUMEN
Introduction: The presence of dyspnea in patients (pts) with COVID- pneumonia is currently known. However, the pathogenetic mechanisms of this symptom remain poorly understood. According to the literature one of the reasons may be pulmonary hypertension. Aim(s): To investigate the role of pulmonary hypertension in the development of dyspnea in patients after COVIDpneumonia. Material(s) and Method(s): investigated 29 pts (men-29 (65.5%), age-58.3(52.2;65.8) years) after 47.4 +/-7 days from onset of COVID-19, with complains on shortness of breath. Was performed clinical examination, computer tomography (CT), echocardiography. Data were processed by non-parametrical statistic. Result(s): It was found that 10(34.5%) pts had pulmonary hypertension (systolic pressure pulmonary artery (SPPA) 39.3(35.4;42.9) mm Hg). The correlation analysis showed that the higher percentage of lung impairment (according to CT) in the acute period of COVID-19 was detected as higher was SPPA in the postCOVID period (fig.1). Conclusion(s): 1) For the differential diagnosis of dyspnea in pts in the postCOVID, it is necessary to determine the level of SPPA;2) Pts with severe lung damage in the acute period of COVID-19 are more likely to develop pulmonary hypertension;3) Pts with pulmonary hypertension in the postCOVID period need an individual approach to the development of rehabilitation program in view of such disorders.
