Percutaneous left atrial appendage occlusion (LAAO) has surged as an effective alternative to treat patients with atrial fibrillation (AF) presenting counterindications for oral anticoagulants. However, the optimal antithrombotic treatment after LAAO is still debated, seeing as it should prevent device related thrombosis (DRT) while minimizing bleeding risk. The aim of this retrospective study carried out...
Currently, many randomized studies have suggested that short-term dual antiplatelet therapy (DAPT) followed by monotherapy reduces bleeding without increasing major cardiovascular events after percutaneous coronary intervention (PCI). A meta-analysis of six randomized studies has shown this benefit using ticagrelor monotherapy after short DAPT. However, there is no data on the results of clopidogrel monotherapy. Researchers...
The MASTER DAPT study analyzed the results of an abbreviated (mean 34 days) vs. conventional dual antiplatelet therapy (DAPT) in 4579 patients treated with angioplasty and a biodegradable polymer sirolimus-eluting stent. This recent publication on the same study analyzed the evolution within the same strategies of the subgroup of patients with complex angioplasty and compared...
The higher the age, the greater the benefit of ticagrelor monotherapy vs. dual antiplatelet therapy (DAPT) in patients with acute coronary syndrome. This post hoc sub-analysis of the TICO study goes along the same lines as the TWILIGHT study (which we recently discussed), given that age is the most common reason for considering that a...
The HOST-EXAM study (which was prospective, randomized, and open-label, with the participation of 37 Korean sites) was specifically designed to determine the role of aspirin as the long-term antiplatelet therapy of choice after angioplasty with current drug-eluting stents. To this end, the study compared aspirin head-to-head with clopidogrel. Over the course of four years, 5438 patients (mean...
Courtesy of Dr. José Álvarez. In patients at high bleeding risk with drug-eluting stents, the duration of dual antiplatelet therapy has been subjected to ongoing review. Guidelines from the European Society of Cardiology (ESC) and the American College of Cardiology (ACC) suggest shortening this treatment to a maximum of three to six months (Class IIb)....
The 1-month outcomes of dual antiplatelet therapy (DAPT) followed by clopidogrel monotherapy were comparable to 12-month DAPT in patients with both simple and complex PCI. There was no significant interaction between DAPT period and procedure difficulty. This is a post hoc study of the STOPDAPT-2 that looked at the complex PCI patient subgroup. It is...
Antiplatelet therapy is key to prevent thrombotic events after a transient ischemic attack (TIA) or ischemic stroke. The role of aspirin is well established in this scenario, but there is emerging evidence for a short period of dual antiplatelet therapy (DAPT). Now, can this strategy avoid recurrent strokes without paying a price in terms of...
Both the indication and discontinuation of antiplatelet therapy to balance ischemic-bleeding risks has been left to physician criterion. However, leaving the decision to one single specialist might not be the best. This is when the team’s role becomes essential. This study looked at the advantages consensus decision-making amongst clinicians, surgeons and anesthesiologists to continue or...
The current guidelines recommend dual antiplatelet therapy (DAPT) 3 to 6 months after transcatheter aortic valve replacement (TAVI). Some recent data finally condensed in the present meta-analysis and recently published in JAHA happen to challenge these guidelines. Clinical studies that investigated single antiplatelet therapy versus DAPT until November 2020 were analyzed and divided according to...
