[Pulmonary ventilation indices of patients following the surgical correction of mitral stenosis].

The method of spiroveloergometry was used in 97 patients after operation of mitral commissurotomy for studying reserves of pulmonary ventilation and its relation to the level of physical working capacity. The results obtained have shown that in patients of worse functional classes the ventilation potency of the lungs deteriorated which resulted in the restricted physical working capacity. It should be necessarily taken into consideration when making programs for the rehabilitation of cardiosurgical patients.
