Popis: Purpose To assess CPET data in young patients with pulmonary sarcoidosis (grade I-II) respectively corresponding parameters in healthy individuals. Methods 99 people aged 25–44 years were examined: 66 people with pulmonary sarcoidosis (PS) I-II grade formed the main group. The control group included 33 healthy, non-smoking people. In both groups the CPET was performed for assessment functional status of cardiorespiratory system. Results Vital capacity and FEV1 didn't differ in both groups (p=0.6 and 0.19). However, Tiffno's index was significantly higher in the control group (p=0.0002). There were no differences in RVOT1, RVOT2, RA volume index in both groups. A comparative analysis of the RV wall thickness revealed that the values in both groups did not exceed the normal limits, but in the main group it was significantly larger (p=0.01). The basal RV diameter at rest were also larger in patients with sarcoidosis (p=0.007). LV contractility at rest was within normal values in both groups, however, in patients with sarcoidosis EF were statistically less than in the control group. At the peak of exercise EF increased more significantly in the control group (p Thus, at the early stages of pulmonary sarcoidosis in young people there are no significant contractility abnormalities both at rest and at the peak of exercise, whereas the EF increase was lower than in healthy individuals. It is necessary to determine GLS RV, which may indicate RV dysfunction preceding the development of LV dysfunction. In patients with sarcoidosis, it's necessary to determine PAP at the peak of exercise, which increased in 79% of cases more than in healthy individuals. This may be due to secondary heart lesion at presence of pulmonary hypertension. The maximum oxygen consumption at the peak of exercise is higher in healthy individuals than in patients with sarcoidosis. So functional reserve was higher in the control group. Thus, the CPET today is an informative diagnostic tool which should be included in the diagnostic algorithms for patients with sarcoidosis.
