Study to Evaluate Effect of Nebivolol on Angina in Women With Microvascular Disease (NIRVANA)
Nebivolol for the Relief of Microvascular Angina in Women
Study Overview
Detailed Description
Though women have less obstructive coronary artery disease (CAD) they continue to have a greater burden of symptoms, more myocardial ischemia, and a higher rate of adverse outcomes than their age-matched male counterparts. This ostensible paradox has led to the recognition of a distinct pathophysiology of ischemic heart disease, in part related to microvascular dysfunction, and abnormal coronary reactivity. The term primary microvascular angina, (MVA) is used to describe a syndrome among patients who have symptoms suggestive of cardiac ischemia, evidence of electrocardiographic abnormalities, abnormalities on stress imaging or a history of ACS, but no evidence of obstructive epicardial coronary disease. In this population, microvascular angina causes significant morbidity and in some may contribute to increased mortality.
The treatment of microvascular disease remains empirical due to lack of data regarding symptom alleviation, as well as ultimate mortality reduction. Women with ischemic heart disease and microvascular angina continue to report more frequent angina and worse quality of life. They frequently seek medical attention for the evaluation of cardiovascular symptoms including chest pain and shortness of breath. Consequently, these women incur greater healthcare costs, with more office visits, hospitalizations, and myocardial infarctions. In fact, more than one half of women without obstructive coronary disease continue to have ischemic symptoms that lead to further consumption of CAD resources, most often because of diagnostic uncertainty.
In the absence of robust outcomes data to drive the care of these women with microvascular ischemia, various approaches are taken, in addition to the fundamental management of baseline risk factors. Some physicians treat these women as they would treat patients with known obstructive CAD, while some, in the setting of "open" coronary arteries and persistent chest pain, opt for reassurance. Nevertheless, given that these women with microvascular ischemia continue to have higher morbidity and mortality, as well as increased resource consumption, there is a widely recognized need for effective therapeutic agents to reduce symptoms, improve quality of life, decrease resource consumption, and ultimately reduce mortality.
Nebivolol, due to its unique antioxidant and vasodilator properties, via its effect on NO bioactivity, and subsequent effects on the endothelium may be a potentially ideal therapeutic agent for the treatment of microvascular angina among women. For example, one previous study showed that nebivolol improved exercise parameters, as well as endothelial function, more effectively than other beta blockade with metoprolol, among patients with persistent angina and non-obstructive coronary disease.
Cardiopulmonary exercise testing is an ideal diagnostic test in this study as it will provide unique information on how microvascular ischemia influences functional capacity as measured through sensitive gas exchange parameters. Because it is known that a distinct pathophysiology contributes to microvascular angina among this subset of women, these parameters provided by CPET may provide essential information regarding the mechanism of symptom mitigation should nebivolol confer therapeutic value.
Furthermore, because exercise tolerance is often significantly impaired, objective measures of gas exchange that reflect submaximum and maximum fitness among these women will be useful both at baseline and on nebivolol.
Peripheral arterial tone and pulse wave analysis will also be performed. PAT signal technology provides a widely validated measurement of endothelium-mediated changes in vascular tone, using non-invasive bio-sensors on the fingertips that are elicited by creating a down-stream hyperemic response. This parameter correlates well with endothelial dysfunction in coronary arteries. We will perform endothelial function testing at baseline and after 3 months.
Metabolomics is an emerging field that offers the possibility of using the body's metabolites to both phenotype a disease as well as track its response to isolated perturbations, such as administration of a drug. In this study we will utilize metabolomics to define signatures of microvascular ischemia as well as nebivolol-mediated changes in metabolic profiles. Baseline metabolic profiling, as well as metabolic profiling after 3 months of nebivolol treatment will be performed in this study.
This type of assessment is an ideal complement to the clinical parameters delineated above as it combines targeted mass spectrometry to measures small molecules related to nitric oxide metabolism (ie: arginine, arginosuccinate, citrulline, ornithine, cGMP, ADMA) as well as more unbiased screening of metabolites that are not known to be associated with either nebivolol exposure or microvascular angina.

Description
Inclusion Criteria:
- 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.
Exclusion Criteria:
- 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

Seattle Angina Questionnaire Score
Time Frame: 3 months
|
Seattle Angina Questionnaire (SAQ): The SAQ is a 5 part survey that is widely used and well validated tool to assess angina stability and angina frequency among patients with coronary artery disease. The SAQ is a validated, self-administered 19-item questionnaire with 5 different dimensions of health status in patients with CAD including: angina frequency, angina stability, disease-specific quality of life, physical limitations and treatment satisfaction. Each SAQ domain score ranges from 0-100, with higher scores indicating a better health status. |

SF36
Time Frame: baseline and 12 week follow-up
|
The SF-36v2 is a commonly used instrument to assess HRQoL8.
The questionnaire evaluates 8 HRQoL domains: physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role emotional and mental health.
The physical component score is a composite of the SF-36v2 physical health domains (physical functioning, role-physical, bodily pain and general health) and the mental component score a composite of the mental health domains (vitality, social functioning, role-emotional and mental health).
Each HRQoL domain score ranges from 0 to 100, with higher scores corresponding to a better health status.
The SF-36v2 domain scores were calculated using the QualityMetric Health Outcomes Scoring Software version 4.5.
