In this podcast, Dr. Valentin Fuster discusses a groundbreaking study from the Orbiter 2 trial, which explores how dobutamine stress echocardiography (DSE) can predict the efficacy of percutaneous coronary intervention (PCI) in relieving angina in patients with stable coronary artery disease. The study reveals that the degree of ischemia, as measured by DSE, is strongly correlated with improvement in symptoms, offering new insights into patient selection for PCI treatment.
