Symptomatic Trial of Angina Assessment Prior to Revascularization (ORBITA-STAR)
September 21, 2023 updated by: Imperial College London
Symptomatic Trial of Angina Assessment Prior to Revascularization: A Placebo-controlled Experiment on Symptoms in Stable Coronary Artery Disease
The principal objective of this research is to determine whether symptoms, induced by confirmed experimental ischaemia, can help us predict which patients will respond to PCI.
