Multivariate Cox Model Showing Risk Factors Associated with Cardiovascular Events

Variables	HR (95%CI)	p
Age, per 5y increment	1.16 (1.05–1.27)	0.003
Stage 1 hypertension at Y1*	1.19 (1.08–1.30)	0.007
Stage 2 hypertension at Y1*	1.27 (1.06–1.48)	0.01
LV mass index regression, per 5% change	0.89 (0.84–0.95)	0.002
LV global longitudinal strain, %	0.97 (0.93–1.01)	0.08

COA: Coarctation of aorta; LV: Left ventricle; HR: Hazard ratio; CI: Confidence interval

Severity of hypertension at Y1 modeled as categorical variable using the normal/elevated BP group as the reference group.

A diagnosis of hypertension pre-intervention was also independently associated with regression of LVMI (β coefficient ± SE: −0.49±0.23, p0.005). However, we did not input both pre-intervention hypertension and post-intervention hypertension in the same model because of collinearity
