Dr. William F. Fearon (USA) is a Professor of Medicine at Stanford University Medical Center, known for his pioneering work in coronary physiology, particularly the development and validation of Fractional Flow Reserve (FFR). As the principal investigator of landmark trials like the FAME series, he played a crucial role in the global adoption of FFR in clinical practice. With over 300 peer-reviewed publications, his leadership in the FAME 3 trial has provided valuable insights into the effectiveness of FFR-guided PCI versus CABG, influencing clinical decision-making and patient management for multivessel coronary artery disease.
