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.
