Stroke, Mortality Risk Vary After Carotid Stenting

HealthDay News — Risk of death or stroke after carotid artery stenting varies widely among U.S. hospitals, with the risk four times higher at some medical centers, new research published in JACC: Cardiovascular Interventions suggests. 

Researchers looked at medical records regarding 19,381 of these procedures from 188 hospitals between 2005 and 2013.

Overall, the researchers found that an average of 2.4% of patients died or suffered a stroke after the procedure, with rates ranging from zero to nearly 19%. After accounting for various factors such as age or prior stroke, the rate of stroke or death ranged from 1.2 to 4.7%. The number of stent procedures performed at a hospital didn't seem to have an effect on subsequent stroke or mortality rates.

"Our findings are important because they demonstrate that carotid stenting is being performed with good results across a large number of hospitals in the United States," the authors write. "However, our analyses also suggest that some hospitals are achieving better outcomes than others, and it will be important to identify the reasons for this so that all centers offering this therapy can achieve exceptional outcomes."
