Study Details

Brief summary:

This research study aims to learn more about the impact the hormone aldosterone on the heart. Primary aldosteronism is a condition where the body's adrenal glands make too much of the hormone aldosterone, which can cause high blood pressure and increase the risk of heart and kidney disease. Treatment with medications that block aldosterone can reduce that risk. This study is trying to learn whether treatment with a medication that blocks aldosterone can improve heart function in people who make too much aldosterone.

Interventions and Outcome Measures

Arms

experimental: Eplerenone Treatment

Eplerenone (50-100mg daily, as tolerated by blood pressure and potassium) for 6 months

Interventions

Eplerenone

After baseline cardiac imaging with PET and echocardiogram, participants will be treated with eplerenone for 6 months at a starting dose of 50mg daily and up to a maximally tolerated dose of 100mg daily, followed by repeat imaging with PET and echocardiogram.

Primary outcome measure

  • Change in myocardial flow reserve (MFR, unitless ratio) [ Time Frame: 6 months ]
