[The diastolic function of the right and left heart ventricles in patients with primary pulmonary hypertension].

To evaluate the condition of left and right ventricular functions in patients with primary pulmonary hypertension (PPH) 21 patients (13 females and 8 males, mean age 35.4 +/- 10.0) were examined. The patients were ill for 5.7 +/- 3.5 years. Ventricular filling was characterized basing on computer data of transmitral and transtricuspid diastolic flow obtained at doppler echocardiography. Right ventricular function proved impaired in all the examinees: early in the disease the speed of early filling (Ve) was inhibited, while late filling was enhanced (Va). At terminal stages of the disease Ve increased, but Va reduced. Left ventricular function was also involved in all the patients: low Ve with the disease progression became more and more evident.
