Abstract: Twelve patients undergoing routine coronary artery surgery received a bolus injection of 1.5 mg/kg enoximone between 8 and 18 hours and again between 18 and 48 hours after operation. No patient showed clinically manifest myocardial heart failure. The haemodynamic and cardiodynamic response to enoximone was quantified over a 30 minutes period following injection. Local myocardial developed force increased by 24 +/- 7% after the first and by 12 +/- 6% after the second injection. The rate of myocardial contraction increased by 50 +/- 14% and 15 +/- 10%, respectively, and relaxation increased by 35 +/- 14% and 22 +/- 19%. There was a decrease in total peripheral resistance of 38.8 and 42.9%, and an increase in heart rate of 11 and 15%. The mean arterial pressure showed small reductions from 73 (+/- 3.7) to 67 (+/- 2.6) mmHg for the first dose and from 83 (+/- 3.1) to 78.4 (+/- 2.8) mmHg for the second. Central venous and pulmonary artery pressures were essentially unaltered. The substantial positive inotropic effect of enoximone has been shown to match its peripheral vasodilatory activity, so that in the normovolaemic patient there is a clinically insignificant small fall in mean arterial pressure.
