    Abstract:
    We have used equilibrium gated blood pool scintigraphy to evaluate the hemodynamic effects and duration of action of molsidomine, a new peripheral vasodilator antianginal drug, after sublingual administration (4 mg) in five patients with heart failure. The following parameters were studied at rest and 10, 60, and 240 minutes after drug administration: left and right ventricular ejection fractions, end-diastolic and end-systolic volumes, stroke volume, heart rate, and cardiac index. Systolic and diastolic blood pressures were determined by cuff measurement. Statistically significant (p less than 0.05) changes were observed after 10 minutes for left ventricular ejection fraction (+26.2%), left and right end-diastolic volume (-12.4% and -15.2%), left ventricular end-systolic volume (-15%), and cardiac index (+7.9%); after 60 minutes for left ventricular ejection fraction (+49%), left ventricular systolic volume (+30.5%), cardiac index (+29.7%), systolic blood pressure (-7.9%), and right ventricular end-diastolic volume (-14.3%); and after 240 minutes for cardiac index (+23.9%), systolic blood pressure (-6.3%), and right ventricular ejection fraction (+23.1%). No changes in heart rate were observed. No patient experienced any side effect. We conclude that the hemodynamic improvement observed with molsidomine can be prolonged and results both from preload and afterload reduction.
