Overview

What we are studying

We are studying whether a medication (eplerenone) will improve oxygen delivery to the heart better than a diuretic medication (chlorthalidone).


Why it is important

High blood pressure is an important factor contributing to heart disease. Even if someone controls their blood pressure, they are still at risk for heart problems, suggesting that there are other contributing factors besides blood pressure. Two of these potential factors are: 1) The ability of the small blood vessels in the heart to deliver blood to the heart muscle; and 2) The ability of the heart to use oxygen.


What we hope to accomplish

The results of this study may potentially help us identify a better way to better prevent heart disease in people with hypertension.

Who can participate

Adults ages 18-75 who have high blood pressure

Who cannot participate

If you have a history of kidney disease, lung disease, HIV, or if you are a current smoker, you will be excluded from the study.

What you may be asked to do

You will be asked to participate in 2 screening visits to determine your eligibility for the study. For eligible individuals, you will be weaned off your current home blood pressure medications and placed on the blood pressure medication enalapril for 1-3 months. You will then be randomized to one of two study medications: eplerenone or chlorthalidone. You will take the medication you are assigned for 9 months total.  At the beginning and end of the 9 month period, you will come into BWH for a Pre-Treatment and a Post-Treatment Assessment, during which the study team will take blood and urine samples and take images of your heart. During the months you are on study drug, you will record your daily blood pressures and report them regularly to the study coordinator in order to monitor your health. During those 9 months, you will also come to BWH for 30-minute in-person safety checks at weeks 1, 3, 6, and months 3, 5, 7.
