    Abstract:
    Prostaglandin E1 (PGE1) is a physiologic vasodilator, which is broadly used in the therapy of peripheral arterial occlusive disease. In addition, the successful use of PGE1 in patients with severe heart failure has been described in several studies, where a decrease in pulmonary artery pressure and an increase in cardiac output were observed. In contrast to these positive effects, the development of lung edema was reported in individual cases after the infusion of PGE1 in patients with heart disease. We therefore conducted a double-blind study to evaluate the effect of PGE1 on extravascular lung water (EVLW) in patients with heart failure (NYHA III-IV) and borderline increased EVLW. Seven patients received an infusion of PGE1 (Prostavasin) at a dosage of 60 micrograms over 2 hours, while in 6 patients (control group) isotonic saline was given as placebo. EVLW was measured using a double indicator method at time points -15 h, -9 h before and at the start of the infusion, 1 h and 2 h during infusion, as well as +1 h, +4 h, +7 h, and +22 h after termination of the infusion. Infusion of PGE1 did not alter EVLW both in comparison to pre-study values (9.8 +/- 4.3 ml/kg bw preinfusion. 9.3 +/- 3.2 ml/kg bw after 1 hour and 9.4 +/- 3.5 ml/kg bw after 2 hours) or to the control group (6.5 +/- 3.3 ml/kg bw preinfusion, 7.1 +/- 2.7 ml/kg bw after 1 hour and 7.0 +/- 3.2 ml/kg bw after 2 hours). We conclude that there is no evidence that PGE1 might contribute to the development, or worsening of lung edema by inducing extravascular lung water accumulation and can, thus, be savely given to patients with even a severe degree of heart failure (NYHA III-IV).
