This study was aimed at gaining device registration from the US Food and Drug Administration (FDA) for a polymer-free biolimus A9 drug-coated stent (BioFreedom, Biosensors). The study had two purposes: on the one hand, it meant to reproduce the results of the LEADERS FREE trial (published in 2015) in terms of safety and efficacy with...
What Antiplatelet Therapy Should We Use in Patients with Stroke/TIA? Interesting Results for the POINT Trial
Courtesy of Dr. Alejandro Lakowsky, MTSAC (Full Member of the Argentine Society of Cardiology) The New England Journal of Medicine (NEJM) recently published an article about the POINT trial (simultaneously presented at the European Stroke Organisation Conference), a long-awaited randomized clinical trial to assess the efficacy and safety of dual antiplatelet therapy (DAPT) with aspirin...
RE-DUAL PCI: Anti-Thrombotic Management in Patients with Atrial Fibrillation and PCI
RE-DUAL PCI outcomes have been published by the New England Journal of Medicine along with their presentation at ESC 2017. The traditional triple anti-thrombotic scheme with dual antiplatelet therapy and warfarin for patients with atrial fibrillation undergoing coronary angioplasty seems to have been left behind. This new study showed that the combination of dabigatran with a P2Y12...
Dual antiaggregation time and death by bleeding
Despite the fact that some randomized studies and meta-analyzis have suggested prolonged dual antiaggregation could be associated to increased death rate, the underlying mechanism remains unclear. It is only logical to assume that if there was an actual increase in mortality associated to prolonged antiaggregation, this should be due to bleeding; however, no studies have...
DAPT Substudy: Score to Personalize Optimal Dual Antiaggregation Therapy Duration
Original Title: Individualizing Treatment Duration of Dual Antiplatelet Therapy after Percutaneous Coronary Intervention: An Analysis from the DAPT Study. Presenter: Yeh RW. Optimal dual antiplatelet therapy duration for patients receiving stents has started to become clearer, but a new scoring method (DAPT Score) may help single out patients who could either benefit or suffer from extended...
OPTIMIZE: 3 months versus 12 months of dual anti-aggregation with zotarolimus-eluting stents
The current recommendation for dual anti-aggregation post-DES implantation is 12 months. However, the ideal length for specific types of stents is unclear. This study aimed to evaluate the clinical non-inferiority at 3 months versus 12 months of dual anti-platelet therapy in patients undergoing coronary angioplasty with zotarolimus-eluting stents. The study randomized 1:1 to 3 months...
SECURITY: 6 months versus 12 months of dual anti-aggregation using 2nd generation DES
This multicenter noninferiority design work included 1399 patients randomized to receive 6 months (n = 682) versus 1 year (n = 717) dual anti-aggregation after implantation of 2nd generation drug-eluting stent. The primary end point was a composite of cardiac death, myocardial infarction, stroke, definite or probable thrombosis, and major bleeding. At 12 months follow-up...
PARIS register: Non-adherence impact to antiplatelet therapy among men and women
The PARIS registry was a prospective observational study in 5018 patients undergoing coronary angioplasty with stent implantation in 15 centers. Three categories were prespecified in the discontinuation of dual antiplatelet therapy: 1) discontinuation for medical guidance, 2) transient discontinuation for less than 15 days for surgery and 3) permanent abandonment of it by non-adherence or...
At least one month of antiplatelet seems sufficient after a zotarolimus -eluting stent
Original title: Lack of association between dual antiplatelet therapy use and stent thrombosis between 1 and 12 months following Resolute zotarolimus-eluting stent implantation. Reference: Silber S, Kirtane AJ, Belardi JA, et al. Eur Heart J. 2014; Epub ahead of print. Dual antiplatelet aggregation optimal time after implantation of a new generation drug-eluting stent (DES) is still discussed. This...
ACC 2024 | ULTIMATE-DAPT Trial
The international guidelines recommend the use of dual antiplatelet therapy (DAPT) with aspirin plus a P2Y12 inhibitor during 12 months in patients receiving percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS), to prevent events such as MI and stent thrombosis. This was a multicenter, placebo controlled, double blind study to determine whether ticagrelor alone,...
