Independent predictors of hypotension and bradycardia after CAS

Variable	End Point	P	OR	95% CI
Asymptomatic stenosis	Hypotension	.03	3.4	1.24–2.30
	Bradycardia	.03	3.1	1.1–1.8
<10 mm to bifurcation	Hypotension	.06	3.8	0.95–14.90
	Drug intervention	.02	2.9	1.2–7.2
Stenosis severity	Drug intervention	.06	1.15*	1.00–1.34
Dilation percentage	Drug intervention	.02	1.17*	1.03–1.33

Note:—OR indicates odds ratio; CI, confidence interval; CAS, carotid artery stent placement.

^*Data are for every 5% increase in stenosis severity or dilation percentage.
