Assessment
Primary outcomes
1) The thresholds of FFR and dPR associated with angina
2) The thresholds of FFR and dPR associated with limited exercise capacity during 6-minute walk test
3) The thresholds of FFR and dPR after PCI associated with the improvement of angina
4) The thresholds of FFR and dPR after PCI associated with the improvement of exercise capacity
5) The thresholds of the gains of FFR and dPR between pre and post PCI associated with the improvement of angina
6) The thresholds of the gains of FFR and dPR between pre and post PCI associated with the improvement of exercise capacity
Key secondary outcomes
1) The distance, the exercise time before the onset of angina, and the proportion of angina during 6-minute walk between patients with and without ischemia
2) RDS score
and SAQ score between patients with and without ischemia
3) RDS score
and SAQ score between patients with and without angina during 6-minute walk
4) The distance, the exercise time before the onset of angina, and the proportion of angina during 6-minute walk between patients with and without ischemia after PCI
5) The distance, the exercise time before the onset of angina, and the proportion of angina during 6-minute walk between patients with and without significant gains of FFR and dPR after PCI
6) Pre and post-test comparison of the distance, the exercise time before the onset of angina, and the proportion of angina during 6-minute walk in patients who did not undergo PCI
7) RDS score and SAQ score between patients with and without ischemia after PCI
8) The pre and post-PCI comparison of RDS score
and SAQ score between patients with and without ischemia after PCI.
9) RDS score and SAQ score between patients with and without significant gains of FFR and dPR after PCI
10) The pre and post-PCI comparison ofRDS score
and SAQ score between patients with and without significant gains of FFR and dPR after PCI
11) The pre and post-test comparison of RDS score
and SAQ score in patients who did not undergo PCI
12) Serum creatinine, eGFR, hemoglobin, HbA1c, LDL cholesterol, BNP, and ejection fraction (EF) between patients with and without ischemia
13) Serum creatinine, eGFR, hemoglobin, HbA1c, LDL cholesterol, BNP, and EF between patients with and without angina during 6-minute walk
14) Serum creatinine, eGFR, hemoglobin, HbA1c, LDL cholesterol, BNP, and EF between patients with and without limited walk distance during 6-minute walk
