Stable AnginaORBITANCT02062593
Objective Randomised Blinded Investigation With Optimal Medical Therapy of Angioplasty in Stable Angina
A study testing Coronary angioplasty in people with Stable Angina, run by Imperial College London at 5 sites in United Kingdom.
Trial summary
In this study the investigators will use careful scientific blinding of patient and their subsequent healthcare staff so that the investigators can determine exactly how much difference coronary angioplasty makes to symptoms and blood supply to the heart. Read more about this study

About this study
Official title: Defining a Gold Standard for Ischaemia: Effects of Interventional Revascularisation Versus Optimum Medical Therapy on Exercise Capacity in Patients With Stable Coronary Artery Disease
In this study the investigators will use careful scientific blinding of patient and their subsequent healthcare staff so that the investigators can determine exactly how much difference coronary angioplasty makes to symptoms and blood supply to the heart. After the 6 weeks blinded phase, all patients will be unblinded and the patients who had undergone sham procedure will be offered the active therapy.
Read the detailed description
The investigators will perform a multi-centre prospective randomised double-blinded comparison of the treatment of stable angina with percutaneous coronary intervention (PCI) and optimal medical therapy (OMT) versus a sham procedure and OMT. Two hundred patients with stable angina and one or more angiographically significant coronary stenosis of 70% or more in a single vessel that is suitable for angioplasty will be recruited. Baseline investigation of functional capacity and myocardial ischaemic burden will be performed. This will be followed by a coronary angiogram and invasive physiological investigation followed by randomisation to PCI or a sham procedure. Follow-up investigation of functional capacity and myocardial ischaemic burden at 6 weeks will then be performed.

Questions about this trial
What is this clinical trial studying?
A study testing Coronary angioplasty in people with Stable Angina, run by Imperial College London at 5 sites in United Kingdom.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 22 Jan 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 5 sites in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 22 Apr 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Exercise Time on Treadmill (time frame: 6 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02062593, which also lists 7 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Jan 2024.
