Brief Summary

INDICATION Microvascular angina. OBJECTIVES To investigate the effect of ACE (angiotensin converting enzyme) inhibition (quinapril) in improving coronary microvascular function. PATIENT POPULATION Women who meet the National Heart, Lung and Blood Institute-sponsored WISE (Women Ischemia Syndrome Evaluation) study criteria of chest discomfort, coronary flow reserve limitations and evidence for myocardial ischemia in the absence of significant coronary artery stenosis. STUDY DESIGN A prospective, randomized, placebo-controlled, comparative trial. TREATMENT Quinapril 80 mg/d versus placebo for four months. PRIMARY EFFICACY PARAMETER(S) Coronary flow reserve (CFR) at Week 16 adjusted for baseline CFR, treatment group assignment, site-specific variables, and site by treatment effects. SECONDARY EFFICACY PARAMETERS Week 16 change in chest discomfort as measured by the Seattle Angina Questionnaire adjusting for baseline values, site, and site by treatment effects. SAFETY PARAMETERS Hematology, blood chemistries, blood pressure and pulse, and frequency and occurrence of adverse events. STATISTICAL RATIONALE AND ANALYSIS A statistical rationale for the number of patients in the study has been provided. Interim analyses are planned after 15 patients have been enrolled in each group. ANTICIPATED TOTAL NUMBER OF PATIENTS 78 (39 per group). ANTICIPATED NUMBER OF PATIENTS AT EACH SITE Approximately 26

Outcome Measures

Primary Outcomes (1)

  • Adjusted coronary flow reserve at Week 16

Secondary Outcomes (1)

  • Chest pain as measured by a Seattle Angina Questionnaire adjusted for baseline values.

Study Arms (2)

Quinapril

ACTIVE COMPARATOR

This arm will receive quinapril which will be started at 40mg daily and titrated to 80mg daily by the end of the first week. After treatment on the maximum tolerated dose for 16 weeks, patients will be reevaluated with coronary angiogram with coronary flow reserve measurements and assessment of angina using the Seattle Angina Questionnaire.

Drug: Quinapril

Placebo

PLACEBO COMPARATOR

This arm will receive placebo for 16 weeks and will be reevaluated with coronary angiogram with coronary flow reserve measurements and assessment of angina using the Seattle Angina Questionnaire.

Drug: Placebo

Interventions

Quinapril will be started at 40mg daily and titrated to 80mg daily for 16 weeks.

Quinapril

Placebo will be given in a capsule form once daily for 16 weeks.

Eligibility Criteria

Age21 Years - 75 Years
Sexfemale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Non pregnant women with chest discomfort 21 to 75 years of age 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.
  • Coronary flow reserve limitation (\<3.0 velocity).

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 providing 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 kept 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 \>3.0) or hepatic disease, surgically uncorrected significant congenital or valvular heart disease and other disease likely to be fatal or require frequent hospitalization 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, unwilling to complete follow-up evaluation including repeat testing.
  • Hypersensitivity to any medications to be used in the study (e.g. angioedema to ACE-I).
  • Documented obstructive hypertrophic cardiomyopathy.
  • Aortic stenosis (valve area \<1.5cm).
  • LV dysfunction (ejection fraction \<=35%).
  • History of cocaine or amphetamine abuse.
  • ACE-I or angiotension 1 (AT-1) receptor blocker use within 30 days or need for continued ACEI/AT-1RB use.
