Association of pulsatile arterial load with LV GLS

Measures of pulsatile arterial load	Model 1	Model 2	Model 3
Log-Zc	0.34 (<0.001)	0.31 (<0.001)	0.28 (0.002)
Log-TAC	−0.28 (0.002)	−0.21 (0.02)	−0.10 (0.3)
AI	−0.31 (<0.001)	−0.10 (0.1)	−0.17 (0.06)

Associations indicated percent change in GLS corresponding to one SD increase in measures of load. Value expressed as regression coefficient (P value). Model 1 adjusted for age, sex; Model 2 adjusted for age, sex, HR; Model 3 adjusted for age, sex, HR, mean load-(SVR), and LVEF. Bold values expressed as regression coefficient (P value).

Abbreviations: AI, augmentation index; GLS, global peak longitudinal strain; SVR, systemic vascular resistance; TAC, total arterial compliance; Zc, aortic characteristic impedance.
