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

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

Dependent variables	EndoS (multiple R ² = 0.22, p <0.01)		MidS (multiple R ² = 0.39, p <0.001)
Dependent variables	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

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.
Variables that did not enter any of the models: gender, coronary artery disease requiring revascularization, systolic blood pressure, diastolic blood pressure, systemic arterial compliance.
