[Clinical and physiological studies of flight personnel with 1st stage hypertensive disease].
An examination of the functional state of the cardiovascular system of 30 pilots with hypertension of the I stage showed that the parameters expressing an increase of the blood ejected to the vascular bed were the most informative hemodynamic and polycardiographic values. It was found that the stroke volume, cardiac output, volume velocity of the ejection, power of the left ventricle, energy expenditure per I 1 of cardiac output and time of the isometric contraction phase increased. The interactions of the cardiac output and peripheral resistance made it possible to distinguish hemodynamic modifications of the hypertensive disease: cardiac-increased cardiac output (15 pilots), vascular--increased peripheral resitance (11 pilots) and mixed--simultaneous increase of both parameters (4 pilots). The identification of the modification is important for proper treatment and expertise.
