    Abstract:
    A haemodynamic study was performed in 12 men aged between 28 and 64 years, including 8 with clinical signs of congestive cardiac failure and an ejection fraction of less than 50 per cent. The pulmonary artery pressure, capillary pressure, left ventricular pressure, cardiac output and the arterial and venous oxygen tensions were measured before (T 0) and after sublingual administration of 4 mg of molsidomine (T 15, T 30, T 45, T 60 min) and 3 minutes after a dose of 0.6 mg sublingual trinitrine (given immediately after the measurements made at T 60). The haemodynamic modifications were very significant at the 30th minute and reached a plateau between the 45th and 60th minute. The left and right ventricular filling pressures fell by more than 25 per cent, the aortic pressure fell by 17 per cent. There was a mild decrease (8 per cent) in the cardiac index and the systolic index, without any significant change in the heart rate. The reduction in the cardiac index and the systolic index was not significant in patients with cardiac failure and an ejection fraction of less than 50 per cent. The peripheral vascular resistance fell by 9 per cent. Finally, there was a significant reduction in the cardiac work and power and especially in the pressure-time index per beat and per minute. The administration of 0.6 mg of sublingual trinitrine induced an additional reduction in the aortic pressure with acceleration of the heart rate and a slight increase in the cardiac output, but no additional venodilator effect was detected.(ABSTRACT TRUNCATED AT 250 WORDS)
