Table 1 In multivariable models, EC in noninfarcted myocardium in obese patients remained associated with the combined endpoint of HHF/death. The addition of ECV improved the classification of individuals at risk (new reclassification improvement, NRI) and the discrimination of the model (integrated discrimination improvement, IDI).
Multivariable Cox regression model | Hazard Ratio for every 5% increase in ECV (95% CI; p value) | Category free NRI (95% CI; p value) | Categorical NRI 0,.05, 0.10 risk categories (95%CI); p value) | IDI (95%CI; p value) |

Modeling composite of HHF or death, stratified by heart failure stage and hospitalization status, adjusted for EF, age, glomerular filtration rate, myocardial infarction size, and gender | 1.97 (1.44-2.70; p<0.001) | 0.43 (0.06-0.76; p=0.02) | 0.04 (0.005-0.079; p=0.02) | 0.069 (0.016-0.132; p=0.02) |
