Figure 4. Comparison of TVF According to LVEF and CFR.

Figure 4

Cumulative incidence of TVF at 5 years are compared among 4 groups classified according to LVEF and CFR. Multivariable marginal Cox proportional hazard regression was used to calculate adjusted HR and 95% CI. The adjusted covariables were age, sex, diabetes, previous myocardial infarction, clinical presentation, multivessel disease, target vessel intervention, pre‐PCI diameter stenosis, pre‐PCI FFR≤0.80, and increased microcirculatory resistance (IMR≥25 or HMR≥2.5). CFR indicates coronary flow reserve; FFR, fractional flow reserve; HMR, hyperemic microvascular resistance; HR, hazard ratio; IMR, index of microvascular resistance; LVEF, left ventricular ejection fraction; PCI, percutaneous coronary intervention; and TVF, target vessel failure.
