[Hemodynamic effects of the association of nifedipine and acebutolol].

The aim of this study was to assess the effects of the association of sublingual nifedipine and intravenous acebutolol on left ventricular inotropism. A series of 30 randomised patients underwent hemodynamic investigation repeated after a 30 minute interval comprising measurement of left ventricular (LVP) and aortic (AoP) pressures and ventriculography (Vo). Between the two Vo, Group I (N = 10) were given 20 mg sublingual nifedipine (N), Group II (N = 0) were given I mg/Kg acebutolol (A) intravenously in 5 minutes, and Group III (N = 10) the association of 20 mg sublingual N and I mg/Kg intravenous A.
