While the benefits of dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 inhibitor are recognized, its primary complication is the occurrence of bleeding events, which negatively impact patient morbidity and mortality. Additionally, about 10% of patients undergoing percutaneous coronary intervention (PCI) are on oral anticoagulant therapy, which significantly increases the risk of bleeding when…
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,…
ESC 2023 | STOPDAPT-3
Short Dual antiplatelet therapy (DAPT), one to three months, followed by P2Y12 inhibitor monotherapy has been shown to reduce bleeding events without increased cardiovascular events vs. standard DAPT, according to guidelines. However, the rate of major bleeding within the first month after procedure remains significant when using these strategies. The use of aspirin-free therapies (ASA)…
Abbreviated Therapy in Patients with Acute Coronary Syndrome: How Safe Is Conservative DAPT Treatment?
Abbreviated dual antiplatelet therapy in patients at high risk for bleeding and acute myocardial infarction. Patients with acute coronary syndrome (ACS) who undergo stent placement (percutaneous coronary intervention, PCI) conventionally require at least 12 months of dual antiplatelet therapy (DAPT) to reduce ischemic events. Patients with ACS who are also at high risk for bleeding…
Rivaroxaban in Acute Coronary Syndrome
Acute coronary syndromes (ACS) involve high mortality risk, especially ST elevation ACS. Their treatment is based on reperfusion, dual antiplatelet therapy (DAPT) and anticoagulation, with enoxaparin (1 mg/kg twice a day) as the preferred anticoagulant according to the contemporary guidelines. 2.5 mg or 5 mg doses of rivaroxaban might be valid alternative treatments for this…
Monotherapy with P2Y12 in Complex Interventions: Less and Less Risky
Monotherapy in patients with complex angioplasty: meta-analysis of 5 randomized studies. Even though prolonged dual antiplatelet therapy (DAPT) might reduce the risk of important ischemic complications, this reduction will come at the expense of a significant increase of bleeding risk, which makes us reassess the cost benefit ratio of this decision. This is also why…
Can We Use DAPT for 3 Months in Acute Coronary Syndrome?
Current guidelines recommend 12-month dual antiplatelet therapy (DAPT) after DES stenting for acute coronary syndrome (ACS) because of elevated MACE risk. The development of more modern stents, with thin and ultrathin struts, compared against prior versions, has resulted in more effective devices in terms of stent thrombosis and restenosis. Prolonged DAPT has been associated with…
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…
P2Y12 Inhibitor Monotherapy vs Aspirin: Results of a Network Meta-Analysis
Revascularization and antiaggregation guidelines have typically recommended aspirin (AAS) as first choice for secondary prevention of cardiovascular events after DES stenting. However, these past few years this strategy has been called into question, seeing as studies have shown the superiority of P2Y12 inhibitor monotherapy (IP2Y12) with clopidogrel or ticagrelor. There is little data comparing both…
Safety and Efficacy of Ticagrelor Monotherapy According to BMI
Obesity is growing dramatically around the world, regardless of income. For instance, 53% of US adults are obese, and 53% of people in the EU are overweight. The actual impact of elevated body mass index (BMI) in antiaggregation safety and efficacy, being it DAPT or SAPT, has not yet been properly looked at. This is…
