[Myocardial contractile function and systemic hemodynamics in hypertensive crises].
The main parameters of central hemodynamics and myocardial contractile function were studied according to the results of the phase analysis of left-ventricular systole in 74 patients with stable stage hypertensive disease during a crisis increase of pressure. It was established that during a crisis increase of pressure, structural changes occur in central hemodynamics, whereas the value of the cardiac output varies within wide limits and the peripheral resistance is obviously increased in all cases. The maximum mobilization of compensatory and reserve possibilities is manifested in intensified inotropic function of the myocardium which contributes to the maintenance of the pumping function and circulation at a level close to normal.
