Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

ORBITA-2 is a double blinded randomised placebo-controlled trial comparing the effects of coronary angioplasty versus placebo procedure on symptoms of stable angina without background anti-anginal therapy. Follow-up will be at 12 weeks.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

ORBITA-2 will enrol patients who meet all 3 of the following criteria:

1. Angina or angina-equivalent symptoms
2. Anatomical evidence of significant coronary stenosis in at least one vessel, either: a. Invasive diagnostic coronary angiogram indicating ≥ 70% stenosis b. CT coronary angiography indicating ≥ 90% stenosis
3. Evidence of ischaemia, arising from at least one of the following options:

1. Positive dobutamine stress echocardiography
2. Positive cardiac MRI perfusion scan
3. Positive nuclear medicine myocardial perfusion scan
4. Invasive pressure wire assessment suggestive of ischaemia, as judged by the interventional cardiologist, at the time of diagnostic angiogram or research angiogram

Exclusion Criteria

1. Age younger than 18
2. Age older than 85
3. Recent acute coronary event
4. Previous coronary artery bypass graft surgery
5. Significant left main stem coronary disease
6. Chronic total occlusion in the target vessel
7. Contraindication to percutaneous coronary intervention or drug-eluting stent implantation
8. Contraindication to antiplatelet therapy
9. Severe valvular disease
10. Severe LV systolic impairment
11. Severe respiratory disease
12. Life expectancy less than 2 years, pregnancy, unable to consent
