NCT03693157

Brief Summary

FFR-guided PCI has been performed in National Taiwan University Hospital(NTUH) for many years. Nevertheless, the method of FFR measurement in NTUH is different from that in literature. In this study, the investigator would like to evaluate the effectiveness and safety of NTUH experience in FFR prospectively. First, the investigator will record any intracoronary (IC) injected adenosine-related complications, such as bradyarrhythmia or chest discomfort. Second, the investigator will follow up on the clinical outcome of the participants for 2 years, record if any target lesion failure, target vessel failure, target vessel-related myocardial infarction, and cardiac death. Finally, left ventricular diastolic pressure, serum pro-brain natriuretic peptide (pro-BNP), and high sensitivity C- reactive protein (hsCRP) will be checked and determined their relationships with the maximum dosage of IC adenosine.
