Table 1 Hazard ratio of CFR for predicting MACE
Study | Variable | Outcome | HR (95% CI) |
|---|---|---|---|
Kanaji 2022 [25] | Corrected g-CFR (per unit increase) | MACEs: all-cause death, nonfatal myocardial infarction (MI), hospitalization for congestive heart failure, and stroke | 0.62 (0.47–0.82) |
Kanaji 2019 [27] | Corrected CSF reserve (per unit increase) | MACE: cardiac death, MI, clinically driven remote (> 3 months after the index PCI) revascularization, or hospitalization for congestive heart failure (HF) | 0.434 (0.270–0.699) |
Indorkar 2019 [22] | CFR (per unit increase) | MACE: death, nonfatal myocardial infarction, heart failure hospitalization, sustained ventricular tachycardia, and late revascularization | 0.808 (95% CI: 0.677–0.964 This model uses LGE size and ischemia extent as continuous variables |
Kato 2017_known CAD [35] | CFR (univariable), (per unit increase) | MACE: cardiovascular death, acute MI, unstable angina, hospitalization for heart failure or ventricular tachyarrhythmia necessitating defibrillation | 0.44 (0.30–0.64) |
Kato 2017_suspected CAD [35] | CFR (univariable), (per unit increase) | MACE: cardiovascular death, acute MI, unstable angina, hospitalization for heart failure or ventricular tachyarrhythmia necessitating defibrillation | 0.36 (0.26–0.49) |
