Study to Evaluate Effect of Nebivolol on Angina in Women With Microvascular Disease

Completed · Phase 4

Conditions studied: Microvascular Angina

In brief

Women have less significant blockages of coronary arteries, however have greater symptoms and worse outcomes compared to their age-matched male counterparts. This paradox has led to the recognition and importance of the microvasculature ( small vessels) as a contributor to symptoms and outcomes. Nebivolol has unique antioxidant properties and dilates blood vessels and it is therefore proposed that treatment with nebivolol will reduce angina (chest symptoms) in women with microvascular disease as well as improve exercise capacity, reduce resource utilization and improve other measures of artery function.

Who can join

Age: 40 and older, up to 80. Sex: female. Healthy volunteers: not accepted.

You may qualify if…

• women between the ages of 40-80
• with evidence of coronary microvascular dysfunction as determined by the presence of rest and or exertional chest tightness and a history of either an elevated troponin level or positive stress test ( EKG criteria or imaging) , as well as non-obstructive coronary artery disease (<50% epicardial obstruction) by either diagnostic catheterization with coronary angiography or CT angiography.

You may not qualify if…

• Women who cannot tolerate a beta blocker.
• Women receiving Hormone Replacement Therapy
• Women of child-bearing age who are not on a birth-control method.
• Women with inability to exercise.
• Women with left ventricular systolic dysfunction (LVEF less than 40%)
• Women who have a medical condition that, in the Investigator's opinion, would expose them to an increased risk of a significant adverse event or interfere with assessments of safety and efficacy during the course of the trial.
• Women with any current malignancy, or any clinically significant hematological, endocrine, cardiovascular, renal, hepatic, gastrointestinal or neurological disease. If there is a history of such disease but the condition has been stable for at least the past year and is judged by the investigator not to interfere with the patient's participation in the study, the patient may be included.
• Women who are unable to speak, read, and understand English and are judged by the investigator to be unable or unlikely to follow the study protocol and complete all scheduled visits.
• Women with any contraindications to beta blocker therapy
• Women with myocardial bridging
• Women with Prinzmetal's angina
