About this trial

The investigators' goal is to show that in hypertensive men and women with left ventricular hypertrophy (LVH) treatment with a mineralocorticoid receptor (MR) antagonist, versus a thiazide-like diuretic, will improve coronary microvascular function and cardiac efficiency, which will associate with improvements in LV structure and function. The investigators will achieve this through a randomized, controlled, basic experimental study involving humans (BESH).

Eligibility criteria

Qualifiers

History of hypertension

Seated systolic BP < 180 mmHg and diastolic < 110 mmHg if on antihypertensives

Seated systolic BP 141-200 mmHg and/or diastolic BP 90-114 mmHg if not on antihypertensives

LVH by echocardiogram

Disqualifiers

Use of MR antagonist (eplerenone, spironolactone, or finerenone) or amiloride (amiloride inhibits ENaC, which is a key mediator of MR's actions) within the past year

Orthostatic hypotension

Major medical illness, including uncontrolled diabetes mellitus (Hemoglobin A1c >7.5)

LV ejection fraction < 40%
