- W2796268889 abstract "Objective To compare the effects of inhaled milrinone and levosimendan on pulmonary and systemic hemodynamics in patients with pulmonary hypertension. Design Prospective, double-blind, randomized controlled study. Setting Tertiary care cardiac institute with 650 beds. Participants The study comprised 150 adult patients with pulmonary hypertension undergoing mitral valve surgery. Interventions Patients were assigned randomly into 1 of the following 3 groups: milrinone (M), levosimendan (L), or control (C); n = 50 per group. In group M, inhaled milrinone (50 µg/kg); in group L, inhaled levosimendan (24 µg/kg); and in group C, normal saline was administered when the patient arrived in the recovery room. Pre-inhalation and post-inhalation hemodynamics (mean arterial pressure [MAP], pulse rate, and systemic vascular resistance [SVR]) were noted until 24 hours of inhalation of the drug. The change in pulmonary artery pressures (pulmonary artery systolic pressure [PASP] and mean pulmonary artery pressure [MPAP]) and the duration for which they remained decreased compared with the control group, were noted. Measurements and Main Results MAP, pulse rate, and SVR were comparable in the 3 groups at various time intervals. PASP and MPAP decreased comparably after inhalation of levosimendan and milrinone. However, they reached levels near the control group values after 2.5 to 3 hours in group L and after 0.5 hours in group M. Conclusions Because inhaled levosimendan causes a decrease in PASP and MPAP without causing a decrease in SVR and MAP, the authors conclude that inhaled levosimendan is a selective pulmonary vasodilator. It is as effective as milrinone in reducing pulmonary artery pressures. In addition, it has advantage over inhaled milrinone because it is has a longer duration of action.
