[Correlation of selected hemodynamic parameters of pulmonary circulation and indices of pulmonary function in patients with mitral stenosis].

The aim of this study was to test if the lung compliance and other indices of pulmonary function correlated with hemodynamic parameters in patients with secondary pulmonary hypertension due to mitral stenosis. 36 patients (mean age 50 years) with mitral stenosis (mean mitral valve area-1.2 cm2), without history of lung diseases were analyzed in the study. 16 patients (group A) were in the II-nd and 20 patients (group B) were in the III-rd and IV-th NYHA class. All patients underwent Swan-Ganz catheterization with evaluation of pulmonary pressures, resistances and pulmonary veins compliance. Pulmonary function tests (spirometry, plethysomography, lung compliance) were also performed. In both analyzed groups the pulmonary artery pressure and pulmonary vein compliance correlated significantly with pulmonary compliance.
