[Reaction to physical load in patients with hypertension with various types of hemodynamics].

Forty-seven patients with stage I essential hypertension (EH) were examined. The external mechanical work of the heart at rest and at the height of submaximum exercise was calculated according to V. L. Karpman et al. The circulatory response to exercise in patients with stage I EH was found to be inadequate and dependent on the type of the central hemodynamics. Patients with hyperkinetic circulatory type were characterized by a decrease in the intensity of the hemodynamic response to exercise. Patients with the eu- and hypokinetic types of the hemodynamics having comparatively small values of the external mechanical performance of the heart at rest responded to exercise by a hyperkinetic reaction ensuring the necessary acceleration of the blood flow.
