Results of Cox Proportional Hazards Models Examining the Relationship Between the L/ESPTI at Baseline and the Risk of Heart Failure During Follow‐Up (Number of Events=135)
| Hazard Ratio Per 1% Increase in L/ESPTI (95% CI) | Standardized Hazard Ratio (95% CI)* | P Value | |
|---|---|---|---|
| Model 1 | 1.22 (1.15 to 1.29) | 1.74 (1.49 to 2.04) | <0.0001 | 
| Model 2 | 1.27 (1.18 to 1.36) | 1.95 (1.60 to 2.36) | <0.0001 | 
| Model 3 | 1.22 (1.14 to 1.32) | 1.76 (1.44 to 2.16) | <0.0001 | 
| Model 4 | 1.24 (1.14 to 1.34) | 1.82 (1.45 to 2.28) | <0.0001 | 
Model 1 is unadjusted (n=6124). Model 2 (n=6124) is adjusted for age, ethnicity, gender, and heart rate. Model 3 (n=6107) is additionally adjusted for diabetes mellitus, systolic and diastolic blood pressure, and body mass index. Model 4 (n=6098) is additionally adjusted for antihypertensive medication use, total cholesterol, HDL cholesterol, current smoking, estimated glomerular filtration rate, aortic augmentation index, and aortic‐to‐radial pulse pressure amplification. HDL indicates high‐density lipoprotein; L/ESPTI, late/early systolic pressure–time integral.
The standardized hazard ratio (HR) is the HR per 1‐SD increase in L/ESPTI. The SD for L/ESPTI is 2.8%.
