Stroke risk predicted by assessment score in patients with hip fractures
Results presented at the Virtual EFORT Congress showed an association between the CHA2DS2-VASc score with risk of stroke, thromboembolism and death among patients with or without atrial fibrillation undergoing treatment for hip fracture.
Using prospectively collected data from the Danish Multidisciplinary Hip Fracture Registry, Thomas Johannesson Hjelholt, MD, PhD, and colleagues computed CHA2DS2-VASc scores for patients older than 65 years of age with first-time hip fractures who either did or did not have atrial fibrillation.
“We then followed patients exactly 1 year forward in time from the date of surgery and searched for outcomes of ischemic stroke, any thromboembolism or death, whichever came first,” Hjelholt said in his presentation, which received the Gold Award for trauma.
Hjelholt noted patients with a CHA2DS2-VASc score of one to three had approximately the same risk of stroke, which was around 1.5% to 2%. He added the risk of stroke increased substantially for each extra point in the CHA2DS2-VASc score.
“Furthermore, please note that the non-[atrial fibrillation] AF patients have approximately the same absolute risk of stroke as the AF patients,” Hjelholt said.
