ABSTRACT
Enoximone, a phosphodiesterase inhibitor, is a positive inotropic agent with direct vasodilator properties. Its acute effects after I.V. administration and the possibility of oral relay were studied in 14 patients (13 men and 1 woman), 40 to 78 years of age (mean 61 years) with Stage IV cardiac failure (NYHA Classification). Eleven patients had dilated cardiomyopathy, 2 had ischemic heart disease and 1 a dilated hypertrophic cardiomyopathy. The haemodynamic inclusion criteria were cardiac index less than or equal to 2.2 l/mn/m2 and pulmonary capillary pressure greater than or equal to 18 mmHg. Patients with cardiogenic shock and severe renal or hepatic failure were excluded. The drug was administered as a bolus of 1 mg/kg followed by a continuous infusion of 5 to 15 g/kg/mn (average 8.9 +/- 2.6 for 7 to 72 hours; average 27 +/- 16 hours). Haemodynamic effects of I.V. administration no change in heart rate, slight lowering of blood pressure, very significant reduction in right atrial and pulmonary capillary pressures, of pulmonary artery pressures, of arteriolo-capillary and systemic resistances and marked increase in cardiac output. General tolerance was excellent with no clinical secondary effects and no signs of hepatic, renal or haematological (platelets) toxicity. Cardiac tolerance was also excellent, no aggravation of preexisting arrhythmias. There was no immediate mortality. Oral relay was undertaken in 14 patients with a daily dose of 300 mg in 12 cases, 400 mg in 1 case and 500 mg in 1 case. Six patients underwent control haemodynamic evaluation on the 8th day there were no signs of the haemodynamic improvement obtained by I.V. administration.(ABSTRACT TRUNCATED AT 250 WORDS)
