Dual-Pathway Antithrombotic Therapy in Patients With Atrial Fibrillation After Percutaneous Coronary Intervention in Stable Coronary Artery Disease: A Single-Center, Single-Operator, Retrospective Cohort Study.

ABSTRACT: Background: There is limited data evaluating the prescription practices for antithrombotic therapy in patients with atrial fibrillation (AF) following elective percutaneous coronary intervention (PCI). Objective: This single-center, single-operator, retrospective cohort study aimed to evaluate trends of antithrombotic treatment strategies in patients with AF undergoing elective PCI. Methods: Patients with AF who electively underwent PCI performed by a single interventionalist between April 2013 and May 2018 were identified. The primary outcome was the antithrombotic therapy at discharge assessed by chart review: triple (TAT, triple antithrombotic therapy) or dual (DAT, dual antithrombotic therapy) antithrombotic therapy and vitamin K antagonist (VKA) or non-vitamin K antagonist oral anticoagulant (NOAC), respectively. Results: Of 6,135 screened patients, 259 met the inclusion criteria. Among these, 133 (51%) patients received NOAC- and 126 (49%) VKA-therapy. Compared with patients on NOAC therapy, patients treated with VKA had higher bleeding risk (mean HAS-BLED-Score; 2.3 vs. 2.0; p = 0.02) and more co-morbidities (estimated glomerular filtration rate <30 ml/min, 11 vs. 4%; p = 0.04; diabetes mellitus, 33 vs. 20%; p = 0.03; history of previous PCI, 37 vs. 21%; p < 0.01). TAT was prescribed more frequently if the prescription included VKA compared with NOAC (61 vs. 41%; p < 0.01). Prescription of TAT and VKA decreased throughout the observed period (2013: 100% vs. 2018: 6%; p < 0.01 and 2013: 91% vs. 2018: 28%; p < 0.01). Conclusion: These observational data from a single center registry show a decrease of TAT- and VKA- prescription in favor of DAT with NOAC. Whether these observations are consistent with national or global trends should to be evaluated in further studies.

Project description:BackgroundCoronary artery disease (CAD) and atrial fibrillation (AF) frequently coexist in clinical practice, making it challenging for the treating physician to choose anticoagulation and antiplatelet therapies. The aim of this study was to investigate antithrombotic strategies and assess related adverse outcomes in stable coronary artery disease (SCAD) and acute coronary syndrome (ACS) patients with AF when the CHA2DS2-VASc score was ≥2.MethodsWe performed a retrospective study and collected data from a computer-based patient record management system in Zhengzhou University People's Hospital in China. In total, 2978 patients with a hospital discharge diagnosis of CAD and concomitant AF who met the inclusion criteria were enrolled from January 1, 2012 to December 31, 2016, and data from 2050 patients were finally analysed. The χ2 test was used to compare the incidences of clinical endpoints between the SCAD+AF group and the ACS + AF group. Multivariable Cox regression analysis was performed to identify independent predictive factors of adverse outcomes in both groups.ResultsOral anticoagulant (OAC) monotherapy was the most common antithrombotic therapy in SCAD+AF patients (49.55%), while double antiplatelet therapy (DAPT) was the most common treatment in ACS + AF patients (54.19%) at discharge. OAC monotherapy significantly increased and the use of single antiplatelet therapy (SAPT) decreased during follow-up (34 ± 13 months) when compared to their use at discharge in the SCAD+AF group (all p < 0.001). In the ACS + AF group, the proportion of patients using DAPT decreased notably, while the proportions of patients using SAPT and dual therapy (DT) combining OAC with SAPT increased significantly during follow-up (all p < 0.001) compared to the proportions at discharge. According to multivariable Cox regression analysis, age, hypertension and prior stroke were independent risk factors for ischaemic stroke in the SCAD+AF group and ACS + AF group (all p < 0.05). OAC was an independent protective factor for ischaemic stroke in both groups (all p < 0.05). Previous bleeding independently increased the risk of haemorrhage in both groups (all p < 0.01).ConclusionsIn this study, the proportion of anticoagulant-antiplatelet combined therapy was low in ACS + AF patients with high stroke risk. In clinical practice, the awareness of anticoagulation needs to be strengthened regarding patients with CAD and AF.

Project description:Background: Warfarin, along with aspirin and clopidogrel, has long been recommended for patients with atrial fibrillation (AF) who are undergoing percutaneous coronary intervention with a drug-eluting stent (PCI-DES). However, this triple therapy has been known to increase the risk of bleeding complications. Meanwhile, there is no evidence from prospective trials on the use of ticagrelor in a dual therapy. We here aimed to compare the antiplatelet drug ticagrelor as a dual antithrombotic agent to aspirin and clopidogrel in bleeding events. Methods: In this multicenter, active-controlled, open-label, randomized trial, patients with AF taking warfarin who had undergone PCI-DES were randomly assigned to the ticagrelor therapy group (Dual group) or the clopidogrel plus aspirin therapy group (Triple group). The primary and secondary endpoints were overall bleeding events and major bleeding events, respectively, according to the Thrombolysis in Myocardial Infarction (TIMI) criteria at 6 months. Cardiovascular events [re-PCI, surgical bypass, myocardial infarction (MI), heart failure, rehospitalization due to angina pectoris, stent thrombosis and death due to cardiovascular causes] at 6 months were also recorded. Results: A total of 296 patients from 12 medical centers in China were randomized after PCI-DES to either the Dual therapy group (n = 148) or the Triple group (n = 146) for 6 months. The overall incidence of bleeding events at 6 months was 36.49% in the Dual therapy group and 35.62% in the Triple group [hazard ratio, 0.930; 95% confidence interval (CI), 0.635 to 1.361; P = 0.7088]. The incidence of the secondary endpoint over 6 months was 4.73% in the Dual therapy group and 1.37% in the Triple group (hazard ratio, 0.273; 95% CI, 0.057 to 1.315; P = 0.1056). Cardiovascular event occurrence was also comparable in both groups at 6 months (18.24 vs. 16.44%; hazard ratio, 0.845; 95% CI, 0.488 to 1.465; P = 0.5484). Conclusions: The incidence of total bleeding events in AF patients treated with ticagrelor was comparable to that in patients treated with clopidogrel plus aspirin at 6 month; Meanwhile, the incidence of cardiovascular events were also comparable between the groups.

Project description:ImportanceAntithrombotic treatment in patients with atrial fibrillation (AF) and percutaneous coronary intervention (PCI) presents a balancing act with regard to bleeding and ischemic risks.ObjectivesTo evaluate the safety and efficacy of 4 antithrombotic regimens by conducting an up-to-date network meta-analysis and to identify the optimal treatment for patients with AF undergoing PCI.Data sourcesOnline computerized database (MEDLINE).Study selectionFive randomized studies were included (N?=?11?542; WOEST, PIONEER AF-PCI, RE-DUAL PCI, AUGUSTUS, ENTRUST-AF PCI).Data extraction and synthesisThe Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used in this network meta-analysis, in which bayesian random-effects models were applied. The data were analyzed from September 9 to 29, 2019.Main outcomes and measuresThe primary safety outcome was thrombolysis in myocardial infarction (TIMI) major bleeding and the primary efficacy outcome was trial-defined major adverse cardiovascular events (MACE).ResultsThe total number of participants included in the study was 11 532. The mean age of the participants ranged from 70 to 72 years, 69% to 83% were male, 20% to 26% were female, and the participants were predominantly white (>90%). Compared with vitamin K antagonists (VKA) plus dual antiplatelet therapy (DAPT) (reference), the odds ratios (ORs) (95% credible intervals) for TIMI major bleeding were 0.57 (0.31-1.00) for VKA plus P2Y12 inhibitor, 0.69 (0.40-1.16) for non-VKA oral anticoagulant (NOAC) plus DAPT, and 0.52 (0.35-0.79) for NOAC plus P2Y12 inhibitor. For MACE, using VKA plus DAPT as reference, the ORs (95% credible intervals) were 0.97 (0.64-1.42) for VKA plus P2Y12 inhibitor, 0.95 (0.64-1.39) for NOAC plus DAPT, and 1.03 (0.77-1.38) for NOAC plus P2Y12 inhibitor.Conclusions and relevanceThe findings of this study suggest that an antithrombotic regimen of VKA plus DAPT should generally be avoided, because regimens in which aspirin is discontinued may lead to lower bleeding risk and no difference in antithrombotic effectiveness. The use of a NOAC plus a P2Y12 inhibitor without aspirin may be the most favorable treatment option and the preferred antithrombotic regimen for most patients with AF undergoing PCI.

Project description:BackgroundIn patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI), selecting an antithrombotic regimen requires balancing risks of ischemic cardiac events, stroke, and bleeding.MethodsWe studied 467 patients with AF undergoing PCI in the time period from December 2015 to July 2018 identified via a chart audit by 47 Canadian cardiologists in the CONNECT AF+PCI (the Coordinated National Network to Engage Interventional Cardiologists in the Antithrombotic Treatment of Patients With Atrial Fibrillation Undergoing Percutaneous Coronary Intervention) study, to determine patterns of initial antithrombotic therapy selection.ResultsThe median (25th, 75th percentile) CHADS2 score was 2 (1, 3), and PCI was performed in the setting of acute coronary syndrome in 62.1%. Triple antithrombotic therapy (TAT) was the initial treatment in 62.7%, dual-pathway therapy in 25.7%, and dual antiplatelet therapy in 11.6%, with a temporal increase in use of dual-pathway therapy during the course of the study; median intended TAT duration was 1 (1, 3) month. Compared with patients selected for TAT, patients selected for dual-pathway therapy were less likely to have prior myocardial infarction (35.8% vs 25.8%, P = 0.045) and prior PCI (33.8% vs 23.3%, P = 0.03), and they received shorter total length of stents (38 [23, 56] vs 30 [20, 46] mm, P = 0.03). Patients selected for dual-pathway therapy had a higher prevalence of prior stroke/transient ischemic attack (13.0% vs 23.3%, P = 0.01). There was no difference in prevalence of anemia (21.5% vs 25.8%, P = 0.30). Use of dual-pathway therapy was similar among patients with acute coronary syndrome and those with stable disease (24.1% vs 28.2%, P = 0.32).ConclusionsApproximately one-quarter of AF patients undergoing PCI are treated with dual-pathway therapy in Canadian practice, with its use increasing during the studied period. Patients selected for dual-pathway therapy have less-complex coronary disease history and intervention.
