FRIDAY, July 31 (HealthDay News) -- Although fewer than 1 percent of patients undergoing percutaneous coronary intervention (PCI) develop a stroke, having a stroke greatly increases the likelihood of in-hospital death, according to a study in the August 1 issue of the American Journal of Cardiology.
Atul Aggarwal, M.D., from the Comprehensive Cardiovascular Medical Group in Bakersfield, Calif., and colleagues analyzed the incidence of stroke using data from 706,782 patients in the National Cardiovascular Data Registry who had undergone PCI.
The researchers found that 0.22 percent of patients developed periprocedural stroke. After controlling for possible confounding factors, stroke was more likely in older patients and in patients with known cerebrovascular disease, acute coronary syndromes, and those with an intra-aortic balloon pump. In-hospital mortality was considerably higher in patients who developed a stroke (30 versus 1 percent).
"In conclusion, stroke developing in association with PCI is rare but a devastating complication," Aggarwal and colleagues write. "Older patients and those with known cerebrovascular disease and acute coronary syndromes appear to be at the highest risk of stroke."
