title: [Effect of physical exercise on aortic blood flow in patients with primary arterial hypertension].
abstract: In 40 patients (30 men and 10 women) aged to 21 to 48 years (mean 42 years) with essential hypertension stage II, according to WHO classification, blood flow was recorder in the ascending aorta by Doppler echocardiography. The investigation was done in erect position, at rest, and during 30 seconds of each phase of exercise on moving track. The control group comprised 20 healthy males aged 23-45 years (mean 38 years). In essential hypertension the values of the heart rate (T), maximal (MAX-V) and mean (ME-V) flow velocity, and systolic volume index (SVI) were significantly higher at rest than in controls. In the 3rd minute of exercise the values of heart rate (T), mean flow acceleration (ACC) and minute volume index (COI) were significantly higher in the patients than in controls. At the peak exercise MAX-V, ME-V and COI were significantly lower than in controls. On the other hand, in the 5th minute after the exercise the values of all the analysed blood flow parametres in the aorta were significantly higher in the patients. After the exercise the fall of the integral flow (INTG) and SVI greater in controls than in patients, while the rise of the mean flow acceleration (ACC) was higher in hypertension than in health.
