title: Haemodynamic effects of oral molsidomine in pump failure complicating myocardial infarction.
abstract: Haemodynamic monitoring, using a Swan-Ganz balloon catheter, was done in 14 patients with pump failure associated with acute myocardial infarction, before and for 8 h after single 6 mg oral dose of molsidomine. The following changes effects were found: HR fell by 1.6 to 4.7% (significant at 4th hour; p less than 0.05); SBP was 8.4% lower after 1 h (p less than 0.05); PCP was decreased by approximately 30%, a significant effect that lasted for 8 hours (p less than 0.002). CI did not change significantly, although individual analysis showed it to have increased in 6 out of 12 cases. Stroke volume index was increased by about 6% (significant after 1 h, p less than 0.025). The left ventricular stroke work index also increased from 9.8 to 24.5% (significant after 1 and 4 h, p less than 0.01 and 0.025). These findings show the beneficial haemodynamic effects of molsidomine in pump failure complicating acute myocardial infarction.
