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...
An Abbreviated Dual Antiplatelet Regimen Is Also Safe in Patients at High Risk for Bleeding Undergoing Complex Angioplasty
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...
ESC 2021 | MASTER DAPT: Dual Antiplatelet Therapy After Coronary Angioplasty in Patients at High Bleeding Risk
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)....
Very Short Dual Antiplatelet Therapy after Complex PCI
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...
Single or Dual Antiplatelet Therapy in Stroke or Transient Ischemic Attack?
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...
Dual Antiplatelet Therapy and TAVR: Obsolete Guidelines
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...
TCT 2019 | Onyx ONE: Durable Polymer vs. Polymer-Free Stent with Only One Month of Dual Antiplatelet Therapy
Courtesy of the SBHCI. This is the first randomized study comparing a durable-polymer drug-eluting stent (zotarolimus-eluting stent Onyx) and a polymer-free drug-eluting stent (biolimus-A9-coated stent BioFreedom), with only one month of dual antiplatelet therapy in patients at high risk for bleeding. Onyx ONE was a study conducted at 84 sites that randomized 1:1 2000 total patients at...
Cardiovascular Risk, Dual Antiplatelet Therapy, and Age. What Should We Know?
Non-adherence to dual antiplatelet therapy varies with age and patients older than 75 years old are those who discontinue treatment most frequently. However, this characteristic in elderly patients was not associated with more cardiovascular events. Treatment compliance protected patients younger than 75 years old from events, while there was increased cardiovascular risk among this population...
Balancing Bleeding Risk vs. Thrombotic Risk to Define Dual Antiplatelet Therapy Duration
Patients who undergo complex angioplasty are at higher ischemic risk, but only benefit from extended dual antiplatelet therapy if there are no factors for high bleeding risk. These data suggest that the bleeding risk must weigh more than the ischemic risk on the determination of dual antiplatelet therapy duration. Complex angioplasty is associated with higher...
ACC 2019 | STOPDAPT-2: P2Y12 Monotherapy After Short-Term Dual Antiplatelet Therapy After Angioplasty
Aspirin is against the ropes: first, it was primary prevention; now, its use is being reconsidered even in relation to angioplasty. There might be paradigm changes as regards antiplatelet therapy after angioplasty. These two studies presented at the American College of Cardiology (ACC) 2019 Scientific Session can really change what we have been doing unquestioningly...
