Table 4. Multivariate Cox regression modelling of left atrial variables adjusted for left ventricular ejection fraction.
Variable | Multivariable hazard ratio | P value |
---|---|---|
LA reservoir strain | 0.920 (0.873–0.969) | 0.002 |
LA booster strain | 0.872 (0.774–0.983) | 0.025 |
LAEF | 0.959 (0.928–0.992) | 0.015 |
LAVImax | 1.030 (0.999–1.061) | 0.055 |
LAVImin | 1.040 (1.007–1.073) | 0.016 |
Data in parentheses are 95% confidence intervals. Each hazard ratio is derived from a separate model containing the LA parameter and left ventricular ejection fraction. LA, left atrial; LAEF, left atrial ejection fraction; LAVImax, maximum indexed left atrial volume; LAVImin, minimum indexed left atrial volume.
