Table 2.
The extracellular volume fraction (ECV) was associated with outcomes in multivariable models. The χ2 statistic measures the strength of association between the predictor variable and the outcome.
| Variable | Mortality Outcome (n=39) | Death, Cardiac Transplant, or Left Ventricular Assist Device Outcome (n=43) | ||
|---|---|---|---|---|
| Hazard Ratio (95% CI) | Wald χ2 | Hazard Ratio (95% CI) | Wald χ2 | |
| Extracellular volume fraction (ECV) (for every 3% increase) | 1.55 (1.27–1.88) | 18.6 | 1.48 (1.23–1.78) | 16.6 |
| Left ventricular ejection fraction (for every 5% decrease) | 1.23 (1.11–1.37) | 14.7 | 1.29 (1.16–1.43) | 23.0 |
| Myocardial infarction size tertile | 1.13 (0.81–1.57) | 0.5 | 1.15 (0.86–1.55) | 0.9 |
| Age (for every 10 year increase) | 1.29 (1.02–1.64) | 4.4 | 1.17 (0.94–1.46) | 1.9 |
