    Abstract:
    The effect of vasodilator Molsidomine (M) vs placebo on left ventricular dimensions and function measured by echocardiography was evaluated in a randomized study on 23 patients (pts) with refractory congestive heart failure (R CF) (NYHA class III-IV). The pts were randomized in two groups: group A (12 pts) received M, group B received an identical appearing placebo. Adequate echocardiograms were obtained before and one hour after 2 tablets of M (4 mg) or P; left ventricular end-diastolic and end-systolic diameters (LVEDD and LVESD), mean rate of circumferential shortening and left ventricular fractional shortening were calculated on the echocardiograms obtained. At the same time mean arterial pressure (MAP) and heart rate were measured. In group A, the single-dose test induced a significant reduction in LVEDD (74.1 +/- 7.2 to 72.1 +/- 7.1 mm; p less than 0.01), in LVESD (64.4 +/- 8.4 to 61.6 +/- 7.4 mm; p less than 0.01) and in MAP (96.5 +/- 8.3 to 85.4 +/- 7.2 mmHg; p less than 0.05). No significant changes were noted in the other parameters. Moreover, changes of parameters evaluated in group A between pts with idiopathic cardiomyopathy and pts with ischemic heart disease showed no statistical differences. Thus, acute Molsidomine therapy is effective in reducing left ventricular diameters and MAP in pts with RCF without changes of echocardiographic contractility indexes.
