Short dual antiplatelet therapy (DAPT) has shown benefits in patients receiving drug eluting stents (DES), reducing bleeding with no concomitant increase in major adverse cardiovascular events (MACE). Traditionally, the therapeutic window was limited to monotherapy with P2Y12 inhibitors during the first year and there are few data on short DAPT followed by long term monotherapy…
Substudy TALOS AMI: from Ticagrelor to Clopidogrel in Patients with High Risk of Bleeding and AMI
The preference for the use of potent P2Y12 inhibitors such as ticagrelor and prasugrel in patients with high risk of acute myocardial infarction (AMI) undergoing percutaneous coronary intervention (PCI) is based on randomized studies and current guideline recommendations. However, clopidogrel is still recommended for patients at high risk of bleeding. Several strategies have been looked…
ESC 2023 | Extended Monotherapy with Clopidogrel vs. DAPT in High-Risk Patients
An increasing number of patients currently present both an elevated ischemic risk and hemorrhagic risk. This means that the selection of the optimal antiplatelet treatment is a clinical challenge. Several studies have shown that P2Y12 monotherapy after minimum dual antiplatelet therapy (DAPT) is a novel strategy to reduce bleeding risk without increasing ischemic risk. Furthermore,…
Is Clopidogrel Monotherapy Safe After a Month of Dual Antiplatelet Therapy in Diabetic Patients?
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…
Abbreviated DAPT in ACS: The End of Clopidogrel Monotherapy?
Compared with patients with chronic coronary syndromes, patients with acute coronary syndromes (ACS) are more likely to suffer from long term major adverse cardiac events (MACE). To prevent this, both the American and the European guidelines recommend prolonging dual antiplatelet therapy (DAPT) in this population for at least 12 months. However, in patients with certain clinical…
HOST-EXAM: The Study that Challenges Aspirin as Long-Term Antiplatelet Therapy
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…
Dual Antiaggregation De-Escalation: A New Paradigm?
De-escalating dual antiaggregation could be the most effective strategy after acute coronary syndrome seeing as it prevents bleeding and cut down costs with no increase of ischemic events. Balancing the effects of dual antiaggregation therapy (DAPT) in the era of potent P2Y12 inhibitors has become the cornerstone of acute coronary syndrome (ACS) management. This meta-analysis…
AAS vs DAPT post TAVI: Meta-Analysis of Randomized Studies
Aspirin monotherapy (ASA) reduced the combined risk of thrombotic and bleeding events compared against dual antiplatelet therapy (DAPT) in patients receiving transcatheter aortic valve replacement (TAVR). This meta-analysis has only reproduced smaller randomize study outcomes and does not include the OCEAN-TAVI registry, the only one that has shown something different so far. Even though ASA…
DAPT vs. Monotherapy: The Dilemma Remains After Surgery
Patients who undergo myocardial revascularization surgery and are discharged on dual antiplatelet therapy (DAPT)—aspirin plus clopidogrel—have a lower risk of major cardiovascular and cerebral events than patients on aspirin monotherapy. Furthermore, the risk of bleeding is not increased for those receiving DAPT. This information comes from a registry of over 18,000 patients recently published in the…
Post TAVR Aspirin vs. Clopidogrel: Conflicting Findings and Guidelines
One month ago we shared a meta-analysis stating aspirin (ASA) as the best antiplatelet following TAVR vs. 3 to 6 dual antiplatelet therapy suggested by guidelines. At that time, guideline recommendations appeared obsolete. Several studies had started to support ASA monotherapy as the best antiaggregation scheme after TAVR. However, in the light of this new…
