Table 2 Predictors of EndoS and separately MidS in multivariate regression analyses

From: Myocardial function in aortic stenosis – insights from radial multilayer Doppler strain

Dependent variables EndoS (multiple R 2   = 0.22, p <0.01) MidS (multiple R 2   = 0.39, p <0.001)
ß P ß p
Age (yrs) −0.11 0.33 0.05 0.60
Hypertension −0.10 0.35 −0.25 0.01
Heart rate (beats/minute) −0.08 0.44 −0.18 0.06
Inferior LV wall thickness (cm) −0.08 0.49 −0.08 0.42
Severe AS by ELI −0.33 <0.01 −0.14 0.17
EpiS (%) 0.08 0.43 0.52 <0.01
  1. LV = left ventricular; ELI = energy loss index; EpiS, MidS and EndoS = peak systolic radial strain in the subepicardial, midmyocardial, and subendocardial layer of the left ventricular inferior wall.
  2. Variables that did not enter any of the models: gender, coronary artery disease requiring revascularization, systolic blood pressure, diastolic blood pressure, systemic arterial compliance.
