Significant (p<0.05) predictor variables for RV dysfunction using logistic regression
| Variable | Univariable | Multivariable |
| LV systolic dysfunction EF<50% | OR 2.84 (CI 1.023 to 7.89) p=0.045 | OR 6.37 (CI 1.24 to 32.84) p=0.027 |
| LV end-systolic dimension (cm) | OR 2.34 (CI 1.32 to 4.14) p=0.003 | |
| D-shaped LV | OR 34.11 (CI 4.42 to 263.07) p=0.001 | OR 24.36 (CI 2.99 to 198.64) p=0.003 |
| PV acceleration time (ms) | OR 0.98 (CI 0.96 to 1.00) p=0.005 | |
| TR Velocity (m/s) | OR 2.42 (CI 1.02 to 5.78) p=0.046 | |
| Pulmonary artery systolic pressure (mm Hg) | OR 1.06 (CI 1.02 to 1.10) p=0.002 | |
| PASP>50 mm Hg | OR 5.61 (CI 1.50 to 21.07) p=0.011 | |
| Pulmonary vascular resistance (Wood units) | OR 3.53 (CI 1.72 to 7.23) p=0.001 | |
| PVR>3.0 | OR 13.07 (CI 2.76 to 61.84) p=0.001 |
Univariable analysis results are given as OR with 95% CI and p value. After testing for collinearity of the predictor variables with p<0.05, multivariable analysis was conducted with significant variables recorded giving OR, 95% CI and p value.
LV, left ventricular; PASP, pulmonary artery systolic pressure; PVR, pulmonary vascular resistance.
