[Hemodynamic effects of intravenously administered celiprolol in patient with coronary heart disease and depressed left ventricular function].

Hemodynamic changes after intravenous application of 10 mg celiprolol-HCl (3-[3-acetyl-4-(3-tert-butylamino-2-hydroxy-propoxy)-phenyl]-1,1-diethyl urea hydrochloride. Selectol; in the following briefly called celiprolol) were investigated over an interval of 30 min in 15 patients with angiographically determined coronary heart disease and depressed left ventricular function (ejection fraction less than 60%, left ventricular end-diastolic pressure (LVEDP) greater than 12 mmHg). One patient suffered from severe left ventricular failure with lung edema and could not be evaluated. The heart rate was not influenced, the arterial pressure was significantly reduced (p less than 0.01), similarly LVEDP (p less than 0.001), and pulmonary pressure (p less than 0.01). Cardiac output and total peripheral resistance were not changed significantly. The hemodynamic working profile of celiprolol in patients with depressed left ventricular function is that of a beta 1-receptor blocker with a strong intrinsic sympathomimetic activity (ISA = Intrinsic Sympathetic Activity) and vasodilating properties--even on preload. The intravenous application of celiprolol in patients with severely depressed left ventricular function can cause pump failure.
