title: [Effects of total flavones of fructus Hippophae (TFH) on cardiac function and hemodynamics of anesthetized open-chest dogs with acute heart failure].
abstract: This study was carried out employing the model of dog with acute heart failure induced by phenobarbital natricum. It was shown that i.v. TFH 4.8 and 9.7 mg/kg could significantly increase CO, CI, + LVdP/dtmax and LVSP; shorten R-dP/dtmax in 9.7 mg/kg; raise - LVdP/dtmax, reduce LVEDP and T value; decrease MVO2I and TPVR; MAP and HR were not changed significantly. The results suggest that i.v. TFH can strengthen cardiac pump function and myocardial contractility in canine with heart failure; significantly improve myocardial diastolic function and hemodynamic performance; markedly decrease myocardia-used oxygen index and total peripheral vessel resistance, thus proving that TFH is good for heart failure.
