[Diagnosis of pulmonary hypertension by means of noninvasive techniques (author's transl)].
On 33 patients with mitralic heart disease (III and IV class N.Y.H.A.) we have carried out polimechanical investigations (ecg, fcg, x-ray examination, external heart impulse record) and the following parameters was determined: 1) interval Q-I sound; 2) interval II sound-OS; 3) Wells's index; 4) Q-I sound/II sound-OS ratio; 5) duration of electromechanical systole of right ventricle; 6) duration of external heart impulse; 7) relative amplitude of E and E1 as percentage of amplitude from E point to nadir point; 8) relaxation isovolumetric time of right ventricle; 9) medium value of pulmonary capillary pressure, total pulmonary resistances, and area of mitral valve. The results demonstrate that there is a correlation between these parameters and the pulmonary blood pressure, whose value is possible to determine as well as haemodynamic investigation. The data indicate validity of non invasive techniques in detecting pulmonary hypertension in mitralic valve diseases.
