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

Active Comparator: Quinapril
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.
Quinapril will be started at 40mg daily and titrated to 80mg daily for 16 weeks.
Placebo Comparator: Placebo
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.
Placebo will be given in a capsule form once daily for 16 weeks.
- Adjusted coronary flow reserve at Week 16
- Chest pain as measured by a Seattle Angina Questionnaire adjusted for baseline values.
