Brief Summary

The enormous and rapidly growing burden of Heart Failure with Preserved Ejection Fraction (HFpEF) has led to a need to understand the pathogenesis and treatment options for this morbid disease. Recent research from the investigator's group and others have shown that pulmonary hypertension (PH) is highly prevalent in HFpEF, and right ventricular (RV) dysfunction is present in both early and advanced stages of HFpEF. These abnormalities in the RV and pulmonary vasculature are coupled with limitations in pulmonary vasodilation during exercise. There are no therapies directly targeted at the pulmonary vasculature that have been clearly shown to be effective in HFpEF. A recent study by Mayo Clinic Investigators has demonstrated pulmonary vasodilation with dobutamine (a beta 2 agonist) in HFpEF. As an intravenous therapy, this is not feasible for outpatient use. In the proposed randomized, placebo-controlled double blinded trial, the investigators seek to evaluate whether the commonly used inhaled bronchodilator albuterol (a beta 2 agonist), administered through a high-efficiency nebulizer device that achieves true alveolar drug delivery, improves pulmonary vascular resistance (PVR) at rest and during exercise in patients with HFpEF as compared to placebo. This has the potential to lead to a simple cost effective intervention to improve symptoms in HFpEF, and potentially be tested in other World Health Organization (WHO) Pulmonary Hypertension groups. PVR is an excellent surrogate marker for pulmonary vasodilation and has been used in previous early trials of PH therapy.

Outcome Measures

Primary Outcomes (1)

  • Change in 20 Watt Exercise Pulmonary Vascular Resistance (PVR)

    The exercise PVR at 20 Watts after study drug relative to the exercise PVR at 20 Watts in the initial assessment prior to study drug. This measurement is made by subtracting pulmonary capillary wedge pressure from the mean pulmonary arterial pressure and dividing by cardiac output in liters per minute and reported as wood units. A decrease in PVR measured by wood units would be considered a favorable response.

    Baseline, 10 minutes after intervention during exercise

Secondary Outcomes (13)

  • Change in Resting Pulmonary Vascular Resistance

    Baseline, 10 minutes after intervention

  • Change in Exercise Pulmonary Capillary Wedge Pressure (PCWP)

    Baseline, 10 minutes after intervention during exercise

  • Change in Resting Pulmonary Capillary Wedge Pressure (PCWP)

    Baseline, 10 minutes after intervention

  • Change in Exercise Pulmonary Artery Compliance

    Baseline, 10 minutes after intervention during exercise

  • Change in Resting Pulmonary Artery Compliance

Limitations and Caveats

This was a proof-of-concept study and chronic effects of albuterol were not examined. Further studies testing more clinically meaningful end points are needed to determine whether beta-agonists will improve patient-centric outcomes.
