These patients have often been through several "re-do" coronary bypass procedures and multiple percutaneous coronary interventions.\n\nSurgical and interventional options for these patients typically have been exhausted or will result in only partial revascularization. Therefore, therapy remains limited to the use of multiple anti-anginal medications, reduced activity, exertion, and stress level, and significant alteration and limitation of lifestyle.\n\nThe goal of this emerging approach is to therapeutically induce the growth and development of new vasculature in zones of severe ischemia in the myocardium, with the hope that new capillaries and arterioles generated will connect to remnant existing vasculature. These neovessels are viewed to act as collaterals, perfusing ischemic territories unapproachable by macro procedures such as PCI and/or CABG.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '80 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n* Male or female, 18 years or older.\n* Diagnosis of chronic stable angina pectoris.
