Brief Summary:
Ischemia-guided revascularization is the cornerstone of contemporary management of coronary artery disease (CAD). Coronary physiological assessment is advocated in the catheter laboratory to guide percutaneous coronary intervention (PCI), and it is widely accepted that an FFR ≤ 0.80 is a good indicator for vessels to benefit from revascularization. Nevertheless, a significant proportion of PCI patients continue to experience adverse events related to both stented segment and/or residual or diffuse disease. Our group recently demonstrated the feasibility of pullback pressure gradient (PPG) derived from virtual Quantitative Flow Ratio (QFR) pullback curve, which is an index of atherosclerosis functional pattern and can be used to epitomize the pathophysiological pattern of CAD as focal or diffuse.
In this regard, the current study will investigate the incremental value of PPG added to QFR haemodynamic assessment in ischemia-causing vessels received PCI in predicting adverse outcomes.

In this regard, the current study will investigate the incremental value of PPG added to QFR haemodynamic assessment in ischemia-causing vessels received PCI in predicting adverse outcomes.
The study cohort is derived from the PANDA-III study (Comparison of BuMA eG Based BioDegradable Polymer Stent With EXCEL Biodegradable Polymer Sirolimus-eluting Stent in "Real-World" Practice) (NCT02017275). In this cohort, vessels with measurable QFR≤ 0.80 will be included. According to the PPG index calculated from QFR virtual pullback curve and treatment strategy chosen, the included vessels were divided into three groups(vessels with PCI strategy and low PPG index (group A), vessels with PCI strategy with high PPG index (group B) and vessels with conservative strategy (group C)) and 2-year clinical outcomes for each group will be compared.
