Multivariable Cox regression analysis to define predictors of all-cause mortality/transplantation
| Parameter | β | SE (β) | Hazard ratio | P-value | (95% CI) |
|---|---|---|---|---|---|
| Age (years) | 0.021 | 0.014 | 1.022 | 0.123 | 0.994–1.050 |
| Gender (m/f) | 1.219 | 0.544 | 3.382 | 0.025 | 1.163–9.833 |
| TAPSE (mm) | −1.719 | 0.887 | 0.179 | 0.053 | 0.032–1.019 |
| Cardiac Index (L/min × m2) | 1.189 | 0.724 | 3.283 | 0.100 | 0.795–13.559 |
| RV free-wall LS (%) | −0.206 | 0.085 | 0.814 | 0.016 | 0.689–0.962 |
| Apical traction (yes/no) | 2.696 | 1.106 | 14.826 | 0.015 | 1.696–129.642 |
| NYHA FC | 1.551 | 0.450 | 4.718 | 0.001 | 1.952–11.401 |
Multivariable Cox regression analysis in which co-variables are age, gender (being male), TAPSE, RV free-wall longitudinal strain, cardiac index, NYHA FC, and AT. Gender and occurrence of AT were encoded as categorical variables, and the rest were encoded as continuous variables.
β, regression coefficient; CI, confidence interval; NYHA FC, New York Heart Association functional class; LS, longitudinal strain; RV, right ventricle; SE, standard error; TAPSE, tricuspid annular plane systolic excursion.
