Table 4.

Cox proportional hazards regression with death as a competing risk showing the association of abnormal GLS and LAVi with incident AF.

	Univariate^*		Multivariate^†
	HR (95% CI)	P value	HR (95% CI)	P value
GLS > -14.7%	3.8 (1.9-7.6)	<0.001	3.2 (1.4-7.5)	0.007
LAVi > 31 ml/m²	5.2 (2.5-10.9)	<0.001	3.8 (1.8-8.2)	<0.001

Each variable is entered in a separate model.

^†

Both variables are included in the same model. Covariates: LVEF, diastolic dysfunction, age, obesity, hypertension, anti-hypertensive treatment, coronary artery disease, LV mass index, relative wall thickness.

HR: Hazard ratio. CI: Confidence interval. GLS: Global longitudinal strain. LAVi: Left atrial volume index.
