  • Research summary

    Narrowing of the coronary arteries can cause chest pain on physical activitiy. This is called angina. Angioplasty of the narrowings is often carried out to relieve this. In the first blinded placebo-controlled trial of this therapy (ORBITA) we found that symptoms were no better than with intensive medical therapy (tablets). In this study we will determine how much difference angioplasty makes to symptoms without background medical therapy using the same scientific blinding of the patient and subsequent healthcare staff. Patients with single and multivessel coronary disease will be eligible. After the 12 week blinded phase, all patients will be unblinded and patients who had undergone placebo will be offered the active therapy.
