The study evaluates the impact of 6 months of treatment with the mineralocorticoid receptor blocking medication eplerenone on the heart’s blood flow, using a cardiac PET stress test, and on the heart’s structure and function by echocardiogram.
Participants with a confirmed diagnosis of primary aldosteronism will undergo echocardiogram and cardiac PET stress test before and after 6 months of eplerenone treatment.
Participants without a confirmed diagnosis of primary aldosteronism but with hypertension and a recent clinical PET test and echocardiogram will undergo testing to make the diagnosis of primary aldosteronism. Those who test positive will go on to treatment with eplerenone for 6 months, followed by a cardiac PET scan and echocardiogram.
