RESUMO

BACKGROUND: Acetylsalicylic acid hypersensitivity (ASAH) limits therapeutic options in patients with acute coronary syndrome (ACS), who benefit from dual antiplatelet therapy (DAPT), especially when undergoing stent implantation. Our aim was to evaluate the safety and efficacy of triflusal in patients with ACS and ASAH. METHODS AND RESULTS: Two-center retrospective study of patients diagnosed with ACS and ASAH from January 1, 2000, to May 1, 2020. Sixty-six patients were treated with triflusal. ASAH was confirmed with tests in 15 patients (22.7%). Forty-nine patients (74.2%) presented history of other drug allergies. Fifty-nine patients (89.4%) underwent stent implantation. DAPT was prescribed for ≥12 months in 54 patients. No adverse reactions to triflusal were reported. During a median follow-up of 5.12 years [IQR 2.7-9.9], rate of cardiovascular (CV) mortality was 6.1%, nonfatal myocardial infarction 12.1%, and ischemic stroke 4.5%. No cases of definite stent thrombosis occurred. Bleeding Academic Research Consortium grade ≥2 was observed in 3 patients during follow-up. CONCLUSION: In this series of patients presenting with ACS and ASA hypersensitivity, triflusal showed good tolerability and was associated with a low rate of CV and bleeding events.

RESUMO

OBJECTIVES: The study sought to examine the risk of ischemic events and bleeding episodes associated with differing antithrombotic strategies in patients undergoing transcatheter aortic valve replacement (TAVR) with concomitant atrial fibrillation (AF). BACKGROUND: Guidelines recommend antiplatelet therapy (APT) post-TAVR to reduce the risk of stroke. However, data on the efficacy and safety of this recommendation in the setting of a concomitant indication for oral anticoagulation (due to atrial fibrillation [AF]) with a vitamin K antagonist (VKA) are scarce. METHODS: A multicenter evaluation comprising 621 patients with AF undergoing TAVR was undertaken. Post-TAVR prescriptions were used to determine the antithrombotic regimen used according to the following 2 groups: monotherapy (MT) with VKA (n = 101) or multiple antithrombotic therapy (MAT) with VKA plus 1 or 2 antiplatelet agents (aspirin or clopidogrel; n = 520). Endpoint definitions were in accordance with Valve Academic Research Consortium-2 criteria. The rate of stroke, major adverse cardiovascular events (stroke, myocardial infarction, or cardiovascular death), major or life-threatening bleeding events, and death were assessed by a Cox multivariate model regression survival analysis according to the antithrombotic regime used. RESULTS: During a median follow-up of 13 months (interquartile range: 3 to 31 months) there were no differences between groups in the rate of stroke (MT: 5%, MAT: 5.2%; adjusted hazard ratio [HR]: 1.25; 95% confidence interval [CI]: 0.45 to 3.48; p = 0.67), major adverse cardiovascular events (MT: 13.9%, MAT: 16.3%; adjusted HR: 1.33; 95% CI: 0.75 to 2.36; p = 0.33), and death (MT 22.8%, MAT: 19.2%; adjusted HR: 0.93; 95% CI: 0.58 to 1.50; p = 0.76). A higher risk of major or life-threatening bleeding was found in the MAT group (MT: 14.9%, MAT: 24.4%; adjusted HR: 1.85; 95% CI: 1.05 to 3.28; p = 0.04). These results remained similar when patients receiving VKA plus only 1 antiplatelet agent (n = 463) were evaluated. CONCLUSIONS: In TAVR recipients prescribed VKA therapy for AF, concomitant antiplatelet therapy use appears not to reduce the incidence of stroke, major adverse cardiovascular events, or death, while increasing the risk of major or life-threatening bleeding.
