The relationship between one-year survival and parameter threshold values: results of the univariate analysis.
| Parameter (Its Threshold Value) | Area Under the Curve (%) | Sensitivity/Specificity (%) | 1-Year Survival/ Non-Survival n (%) | p-Value | Non-Survival Group OR (95% PI) |
|---|---|---|---|---|---|
| RV EF <25.5% | 69.1 | 50.0/89.7 | 4 (10.3)/5 (50.0) | 0.011 | 8.75 (1.741–43.973) |
| NT-proBNP >1738 (ng/L) | 76.1 | 88.9/60.5 | 15 (39.5)/8 (88.9) | 0.008 | 12.267 (1.389–108.325) |
| RPA RAC <19.075% | 77.8 | 100.0/52.8 | 17 (47.2)/5 (100.0) | 0.027 | - |
| LV GLS >−14.183% | 75.6 | 77.8/86.7 | 4 (13.3)/7 (77.8) | 0.001 | 22.75 (3.432–150.811) |
Definition of abbreviations: ROC—receiver operating characteristics; RV EF—right-ventricular ejection fraction; NT-pro-BNP—brain natriuretic peptide; RPA RAC—right pulmonary artery relative area change; LV GLS—left-ventricular global longitudinal strain. The p-values were determined using the Mann–Whitney test. OR—odds ratio; CI—confidence interval.
