[Value of different indirect methods of diagnosis of pulmonary hypertension].
Dependence of the duration of right-ventricular isometric relaxation phase (IRP) on right ventricular systolic pressure (SP) and heart rate was studied. IRP was measured using echography of the tricuspid valve and SP value was determined according to the data of heart venous catheterization. Examination included 30 patients with chronic inflammatory pulmonary diseases. A low dependence was found between IRP, SP and HR, which is of little use for the indirect establishment of the pressure value in pulmonary circulation. Errors during right-ventricular SP measurement using methods based on the IRP analysis show their unreliability. A method for measuring pressure value in pulmonary circulation has been suggested which is based on the data of echography. Despite the high correlative coefficient of the estimated and actual values, the method makes it possible to obtain only the approximate data.
