Summary

The purpose of this study is to evaluate the safety, tolerability and mechanistic effects of spironolactone, an aldosterone receptor antagonist, on sympathetic nervous system activity and right heart function and remodeling in patients with chronic right heart failure.

Conditions

  • Chronic Right-Sided Heart Failure
  • Pulmonary Arterial Hypertension
  • Pulmonary Hypertension, Primary, 2
  • Pulmonary Hypertension, Primary, 3
  • Pulmonary Hypertension, Primary, 4
  • Cardiomyopathy Right Ventricular

Interventions

DRUG

Spironolactone

Spironolactone 12.5mg daily up to a maximum dose of 50 mg daily if tolerated for a total duration of 12 weeks.

DRUG

Placebo

Placebo daily for a total of duration of 12 weeks

RADIATION

PET/CT Scan: Two PET scans using 1. C-11 HED and 2. N-13 Ammonia or rubidium-82

At baseline and 12 weeks, all participants will undergo rest perfusion PET imaging according to standard protocols with either 82-Rb or N-13 NH3, followed by C-11 HED PET.

DIAGNOSTIC_TEST

Cardiac MRI (Gadolinium enhanced)

At baseline and 12 weeks all participants will undergo cMR to assess RV function and structure. We will acquire precontrast T2 and native T1 maps, and post gadolinium T1 maps.
