Real-World Studies of Carotid Artery Stenting Demonstrate Results Comparable to Guidelines for Patients Treated Wi...(Heart Association published its 30 day o...),Health

Date:10/23/2007

Heart Association published its 30 day outcome guidelines in Circulation for patients treated with carotid artery surgery. These guidelines were based on the observed stroke and death rates in patients with carotid artery disease who had undergone surgery, or carotid endarterectomy, to treat their condition. The patients who underwent carotid artery surgery were at standard risk for experiencing an adverse event from surgery. Abbott's post-marketing CAPTURE 2 and EXACT studies are the first real-world carotid artery stenting studies to demonstrate results comparable to these goals.

About Abbott's CAPTURE 2 and EXACT Post-Marketing Clinical Studies

The CAPTURE 2 study included 1,987 patients and utilized Abbott's ACCULINK(TM) Carotid Stent System and ACCUNET(TM) Embolic Protection System. The EXACT study included 2,124 patients and utilized Abbott's Xact(R) Rapid Exchange Carotid Stent System and Emboshield BareWire(TM) Rapid Exchange Embolic Protection System. The key objective of both trials was to determine whether carotid stenting could be performed safely in real-world clinical setting by physicians with varying levels of experience. The primary endpoints were death, stroke and MI at 30 days. The demographics of patients in both trials were similar.

The 30-day composite endpoints of stroke and death for patients in the CAPTURE 2 and EXACT studies were:

-- 3.1% and 3.0% combined stroke and death in CAPTURE 2 and EXACT patients

without symptoms under age 80

-- 6.0% and 7.3% combined stroke and death in CAPTURE 2 and EXACT patients

with symptoms under age 80

-- 3.8% and 4.0% stroke and death within 30-days of treatment for the

combined patient populations

"We are very pleased with the findings from the CAPTURE 2 and EXACT trials, which show that patients treated with Abbott's ACCULINK and XACT carotid artery stent systems can have outcomes comparable to those of patients who undergo carotid surger
