Antithrombotic Therapy and Outcomes of Patients With New-Onset Transient Atrial Fibrillation After ST-Segment Elevation Myocardial Infarction
Conclusions: There is not a widely accepted treatment algorithm in patients with STEMI who complicated with new-onset AF in clinical guidelines. The current study indicated that transient form of new-onset AF might not require long-term VKA. Besides, addition of VKA to DAPT therapy may increase the rates of major and minor bleeding.

Antithrombotic treatment in peripheral artery disease.
Abstract This review treats antithrombotic use for peripheral arterial disease (PAD). In asymptomatic patients, there are no scientific data to support single antiplatelet therapy (SAPT) for primary prophylaxis. In symptomatic PAD, SAPT with aspirin or clopidogrel is indicated. The efficacy of aspirin is controversial. Clopidogrel may be preferred over aspirin. Ticagrelor is not superior to clopidogrel in reducing major adverse cardiovascular events and major adverse limb events, but lowers the risk of ischaemic stroke. In symptomatic PAD, dual antiplatelet therapy (DAPT) with clopidogrel and aspirin does not prov...

Predictors of Mortality in Patients with Atrial Fibrillation (From the Atrial Fibrillation Clopidogrel Trial with Irbesartan for Prevention of Vascular Events ACTIVE a)
The mortality rate of most patients with atrial fibrillation (AF) exceeds the stroke rate, but predictors of mortality have not been well defined. The Atrial Fibrillation Clopidogrel Trial with Irbesartan for prevention of Vascular Events (ACTIVE) recruited AF patients who were unsuitable to receive vitamin K-antagonists and were randomized to aspirin alone vs. aspirin plus clopidogrel. We investigated independent predictors of all-cause mortality by multivariable Cox regression analysis and explored interactions with assigned antiplatelet therapy.

Is there a role for oral triple therapy in patients with acute coronary syndromes without atrial fibrillation?
CONCLUSION: More potent antithrombotic regimens increase bleeding and should only be considered on an individual basis, after careful risk stratification. Accurate risk stratification of ACS patients, for both ischaemic and bleeding risk, is essential to allow individualised treatment. PMID: 29345587 [PubMed - as supplied by publisher]

Optimal antithrombotic treatment of patients with atrial fibrillation undergoing percutaneous coronary intervention: triple therapy is too much!
Abstract Patients with atrial fibrillation who undergo a coronary intervention are eligible for both anticoagulation and (dual) antiplatelet therapy ((D)APT). An optimal balance has to be found to reduce the thromboembolic risk (i.e. stroke, systemic embolism and myocardial infarction) and to minimise the increased risk of bleeding with concomitant use of an anticoagulant and (D)APT. Owing to a lack of evidence, the guideline recommendations are predominantly based on expert opinion. Current evidence indicates that the combination of a non-vitamin K oral anticoagulant (NOAC) and clopidogrel is safer than vitam...

Pharmacodynamic safety of clopidogrel monotherapy in patients under oral anticoagulation with a vitamin K antagonist undergoing coronary stent implantation.
This study enrolled 100 patients on aspirin plus clopidogrel (DAPT-cohort, without indication for VKA) and 100 patients on clopidogrel monotherapy plus phenprocoumon (OAC-cohort) undergoing elective PCI. Platelet reactivity was assessed by impedance aggregometry on day 1 following PCI. Ischemic (death, stroke, or myocardial infarction) and bleeding (BARC 2-5) events within 12 months were compared in a propensity score adjusted model. Platelet reactivity was not different in the OAC- and DAPT-cohort (187 [127-242] vs. 167 [126-218] AU×min; p = 0.23). Overall, 17 ischemic and 34 bleeding events were recorded during follo...

EP News: Clinical
Sindet-Pedersen et  al (J Am Coll Cardiol 2018;72:1790, PMID 30286922) investigated the risk of bleeding, ischemic stroke, myocardial infarction (MI), and all-cause mortality associated with direct oral anticoagulants (DOACs) compared with vitamin K antagonists (VKAs) in combination with aspirin, clopidogrel, or both in patients with atrial fibrillation (AF) after MI and/or percutaneous coronary intervention (PCI). Overall, 3222 patients were included in the retrospective registry analysis; 875 (27%) were treated with VKA+single antiplatelet therapy (SAPT), 595 (18%) were treated with DOAC+SAPT, 1074 (33%) were treated wi...

Benefits and Risks of Anticoagulation in Acute Coronary Syndrome
Conclusions: Many risk factors for ischemic events and bleeding overlap. The clinician's challenges include monitoring patients' adherence and global assessment of the antithrombotic effect that incorporates antiplatelet and anticoagulant effects.

Clinical Outcomes of Antithrombotic Strategies for Patients with Atrial Fibrillation After Percutaneous Coronary Intervention.
This study aims to explore the best antithrombotic strategy for AF patients after PCI based on a network meta-analysis. This study was registered in PROSPERO (CRD42018093928). The PubMed, Cochrane, and EMBASE databases were searched to identify clinical trials concerning antithrombotic therapy for AF patients with PCI from inception to April 2018. Pairwise and network meta-analysis were conducted to compare clinical outcomes of different antithrombotic therapy. The primary endpoint was major bleeding. Fifteen studies including 16,382 patients were identified with follow-up ranging from 3 to 12 months. Non-vitamin K oral an...

Comparison of effects of triple antithrombotic therapy and dual antiplatelet therapy on long-term outcomes of acute myocardial infarction
This study aimed to compare the long-term outcome of triple antithrombotic therapy (TAT) with that of dual antiplatelet therapy (DAPT) after AMI. This was a nationwide, propensity score-matched, case –control study of 186,112 first AMI patients, of whom 2,825 received TAT comprising aspirin, clopidogrel, and warfarin. Propensity score matching in a ratio of 1:4 by age, sex, comorbidities, and treatment was adopted, Finally, 2,813 AMI patients and 11,252 matched controls that were administered TAT and DAPT (aspirin and clopidogrel), respectively, were included in our analysis. The 12-year overall survival rate did not dif...

The WOEST  2 registry : A prospective registry on antithrombotic therapy in atrial fibrillation patients undergoing percutaneous coronary intervention
CONCLUSIONS: Patients on combined oral anticoagulation and antiplatelet therapy undergoing PCI are elderly and have both a high bleeding and ischaemic risk. Over time, a NOAC plus clopidogrel became the preferred treatment. The rate of thrombotic and bleeding events was not significantly different between patients on triple or dual therapy or between those on VKAs versus NOACs.PMID:35230636 | DOI:10.1007/s12471-022-01664-0

Current status of antithrombotic therapy and in-hospital outcomes in patients with atrial fibrillation undergoing percutaneous coronary intervention in Germany
CONCLUSION: The preferred therapy after PCI in patients with AF is DAT with a NOAC and clopidogrel. In-hospital ischemic and bleeding events were rare. The recommended durations for combination therapy vary considerably.PMID:35243515 | DOI:10.1007/s00059-022-05099-6
