Coronary sinus filling time: A novel method to assess microcirculatory function in patients with angina and normal coronaries

摘要

ObjectiveDysfunction of the coronary microcirculation is considered as one of the factors responsible for symptoms and abnormal stress tests in patients with angina and normal coronaries (syndrome X). We sought to evaluate the usefulness of coronary sinus filling time (CSFT) to assess coronary microcirculation in this group of patients.
