EWISE: Study of Eplerenone in Women With Chest Pain, Coronary Vascular Dysfunction and Evidence of Myocardial Ischemia

Completed · Phase 4 · Has a placebo group

Conditions studied: Ischemic Heart Disease

In brief

Some women have chest pain even without having a blockage in one of the major blood vessels that supplies blood to the heart. In many of these women the microscopic (small) blood vessels in the heart do not function normally. This study seeks to determine if treatment with eplerenone, a commercially available diuretic, can improve the function of these microscopic blood vessels and, possibly, improve the chest pain.

Who can join

Age: 21 and older, up to 75. Sex: female. Healthy volunteers: not accepted.

You may qualify if…

• Non-pregnant women with chest discomfort who are 21 to 75 years of age and from diverse racial/ethnic groups.
• Suspected ischemic heart disease (IHD) but no severe coronary stenosis (> 50% diameter reduction) on coronary angiography used to qualify for WISE.
• Endothelial dysfunction, defined as failure to dilate to intracoronary acetylcholine (< 5% increase in mean lumen diameter).
• If possible, patients should be taking stable, maximally tolerated dose of either an angiotensin-converting enzyme inhibitor [ACEI] (or an angiotensin II receptor blocker [ARB] if ACEI intolerant)

You may not qualify if…

• Women who are breast-feeding or who are pregnant. Women of childbearing potential may be enrolled but must agree not to become pregnant during the course of the study and must practice a method of birth control considered reliable by the investigator. If established on hormonal contraceptives for more than 3 months, patients will be allowed to participate provided that this therapy remains constant throughout the study. If a patient becomes pregnant or begins breast-feeding during the study, she must be withdrawn immediately.
• Acute ischemic syndrome defined as acute myocardial infarction [MI] (by enzyme or electrocardiogram [ECG] criteria) or unstable angina within 1 month of entry.
• Uncontrolled moderate hypertension: sitting blood pressure > 160/95mmHg with measurements recorded on at least 2 occasions (for blood pressure control patients must first be stabilized, preferably with a diuretic, and remain on that dosing regimen throughout participation in the study).
• Severe heart failure defined as New York Heart Association (NYHA) Class III or IV on treatment.
• Coronary revascularization by either coronary artery bypass grafting (CABG) or percutaneous transluminal coronary angioplasty (PTCA) or stent placement.
• Conditions likely to influence outcomes independent of IHD: severe lung, renal (creatinine >1.8 or creatinine clearance [CrCl] ≤ 50ml/min) or hepatic disease; surgically uncorrected significant congenital or valvular heart disease; and other diseases likely to be fatal or require frequent hospitalizations within the next six months.
• Adherence or retention reasons: recent alcoholism or drug abuse; psychiatric illness including severe depression; dementia; active participation in any other research trial other than WISE; or unwilling to complete follow-up evaluations including repeat testing.
• Hypersensitivity to any medications to be used in the study
• Documented obstructive hypertrophic cardiomyopathy.
• Aortic stenosis (valve area < 1.5cm).
• Left ventricular (LV) dysfunction (ejection fraction <= 35%).
• History of significant cocaine or amphetamine abuse.
• Serum potassium > 5.0meq/l at baseline
• Taking potent CYP3A4 inhibitors (ketoconazole, itraconazole, nefazodone, troleandomycin, clarithromycin, ritonavir, nelfinavir)
• Intolerance to ACEI and ARB medications
• Use of potassium supplements or potassium sparing diuretics
