Patients are prescribed DAPT, a combination of aspirin and an anti-platelet medication, following stent implantation to protect them from developing blood clots and experiencing other adverse safety events. The most recent European Society of Cardiology (ESC) guidelines for myocardial revascularization, which were published in 2010, recommend that patients treated with a DES remain on DAPT for six to 12 months. Long-term DAPT use can lead to additional safety risks, such as increased bleeding events, which is why shorter-term duration of DAPT may be meaningful for patients. In addition, having a shorter DAPT duration after stent implantation may be beneficial in case a patient needs to interrupt or discontinue the medication prior to surgery or for other considerations.
"With this new indication, physicians in Europe can have confidence in being able to safely discontinue DAPT after a minimum of three months for patients who were treated with a XIENCE PRIME or XIENCE V stent should their patients' circumstances require it," said Charles A. Simonton, M.D., FACC, FSCAI, divisional vice president, Medical Affairs, and chief medical officer, Abbott Vascular. "Clinical data from more than 10,000 patients show that XIENCE is associated with similar safety results in patients who interrupted their DAPT medication after three months compared to patients who never interrupted their medication. Reducing the amount of time patients need to remain on DAPT can have a significant impact on patient health and may lead to decreased health care costs. We are pleased that XIENCE has been recognized as the only major DES in Europe with a minimum three-month indication for DAPT - a confirmation of its strong safety profile."
Data presented at the EuroPCR 2012 congress this week demonstrated that in more than 10,000 real-world patients treated with XIENCE PRIME and XIENCE V, no cases of stent thrombosis were reported in patients who discontinued DAPT after three months post-stent implantation.
About XIENCE PRIME and XIENCE V
Abbott's market-leading XIENCE family of drug eluting stents (XIENCE PRIME and XIENCE V) is available in the United States, Europe, Japan and other international markets.
XIENCE PRIME is indicated for improving coronary artery luminal diameter in patients with symptomatic heart disease due to de novo native coronary artery lesions (lesions ≤32 mm) with reference vessel diameters of ≥2.25 mm to ≤4.25.
XIENCE V is indicated for improving coronary luminal diameter in patients with symptomatic heart disease due to de novo native coronary artery lesions (lesions ≤28 mm) with reference vessel diameters of 2.25 mm to 4.25 mm.
Everolimus, developed by Novartis Pharma AG, is a proliferation signal inhibitor, or mTOR inhibitor, licensed to Abbott by Novartis for use on its drug eluting vascular devices. Everolimus has been shown to inhibit in-stent neointimal growth in the coronary vessels following stent implantation, due to its anti-proliferative properties.
