Summary

BACKGROUND There is no effective medical treatment for heart failure with preserved ejection fraction (HFpEF). Increases in pulmonary capillary wedge pressure (PCWP) develop in patients with HFpEF. Prostacyclin analogo can possible reduced PA pressure along with PWCP pressure, as with exercise.

OBJECTIVES This study try to determine whether inhlalation of iloprost improves exercise hemodynamics and cardiac reserve in HFpEF.

METHODS In a double-blind, randomized, placebo-controlled, parallel-group trial, subjects with HFpEF underwent invasive cardiac catheterization with simultaneous expired gas analysis at rest and during exercise, before and 15 min after treatment with either inhaled iloprost or matching placebo.

Conditions

  • Heart Failure With Normal Ejection Fraction

Interventions

DRUG

Iloprost

Investigators performed cardiac catheterization as previously described. Hemodynamic values were recorded for the first exercise phase (before any drug administration) and after return to steady state baseline hemodynamic values, and the second exercise phase (after drug administration). Subjects were randomized 1:1 to inhalation of placebo (normal saline solution) or iloprost (50 mg/kg/min) (Bayer Pharmaceuticals, Scottsdale, Ari-zona) for 5 min. The iloprost/placebo inhalation were identical in appearance and prepared by the research pharmacy, ensuring double-blinding of inhalation content. After finishing inhalation process for 10 min, hemodynamic measurements were repeated at rest, followed by repeat supine exercise at a 20-W workload for 6 min, identical to the study's first phase.
