NCT02262078

Brief Summary

Heart failure with preserved ejection fraction (HFpEF) is a major public health problem that has no proven effective treatment. This study will assess the effects of nebulized inhaled nitrite administration on resting and exercise hemodynamics in patients with HFpEF referred to the catheterization lab.

Outcome Measures

Primary Outcomes (1)

  • Change in Pulmonary Capillary Wedge Pressure During Exercise

    Pulmonary capillary wedge pressure is a measure of cardiac filling pressure, measured in millimeters of mercury (mmHg)

    Baseline, after study drug dosing, approximately 4 minutes after starting exercise

Study Arms (2)

Placebo (Saline)

PLACEBO COMPARATOR

Participants receive normal saline, administered by inhalation over 10-15 minutes, using a nebulizer

Other: Placebo

Sodium Nitrite

EXPERIMENTAL

Participants receive Sodium Nitrite inhalation solution, administered by inhalation over 10-15 minutes, using a nebulizer

Drug: Sodium Nitrite Inhalation Solution

Interventions

90mg of (nebulized) inhaled sodium nitrite will be administered (by inhalation) to participants prior to exercise.

Also known as: AIR001, NaNO2, Sodium Nitrite
Sodium Nitrite
PlaceboOTHER

Normal saline will be administered (by inhalation) to participants prior to exercise.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Heart Failure with preserved Ejection Fraction (HFpEF) is defined by clinical symptoms of dyspnea and fatigue
  • Normal left ventricular ejection fraction (\>/=50%)
  • And elevated Left Ventricular (LV) filling pressure at cardiac catheterization (defined as resting Pulmonary Capillary Wedge Pressure (PCWP)\>15 mmHg and/or PCWP \>/=25 mmHg during exercise).

You may not qualify if:

  • Systolic Blood Pressure \<120 mmHg (during catheterization)
  • Prior nitrate therapy (within previous 2 weeks)
  • Glucose-6-Phosphate Dehydrogenase (G6PD) deficiency
  • Other "non-HFpEF" specific causes of heart failure such as significant valvular disease (\>moderate left-sided regurgitation, \>mild stenosis)
  • Severe pulmonary disease
  • Unstable coronary disease or coronary spasm
  • Primary renal or hepatic disease (end stage renal failure/on dialysis or clinical diagnosis of hepatitis or hepatic cirrhosis)
  • Constrictive pericarditis, or infiltrative, restrictive, or hypertrophic cardiomyopathies
  • Pregnant

Limitations and Caveats

Patients with symptoms that might independently cause symptoms were excluded, including severe valvular or coronary heart disease and advanced lung, liver or kidney disease. Cannot determine if results would apply to these co-morbidities.
