Study flowchart. Among 1170 patients with analyzable post-percutaneous coronary intervention Murray law-based quantitative flow ratio assessments, 155 (13.2%) with abnormal post-percutaneous coronary intervention Murray law-based quantitative flow ratio in either left anterior descending or left circumflex artery, in spite of “successful” percutaneous coronary intervention by angiographic criteria, were attributed to residual ischemia group. LAD, left anterior descending; LCX, left circumflex artery; LM, left main; RVD, reference vessel diameter; STEMI, ST-segment elevation myocardial infarction; NSTEMI, non-ST-segment elevation myocardial infarction; PCI, percutaneous coronary intervention; μQFR, Murray law-based quantitative flow ratio.
