[Multifactorial analysis of the hemodynamic reactions to a physical load in hypertension]

Multifactorial analysis of findings from 66 essentially hypertensive patients and 14 normal subjects investigated during bicycle ergometry (250 and 500 kgm/min) demonstrated a relationship between hemodynamic changes and the patient's baseline status, age and stage of the disease. Hypertensive patients showed greater AP response to exercise and smaller changes in heart productivity and vascular tone, as compared to normal subjects with similar resting hemodynamic status. Patients with high resting AP and CI values showed smaller shifts during bicycle ergometry, as compared to other patients at the same stage of the disease, while diastolic AP increase was more pronounced in elderly patients.
