Antithrombotic Therapy After Percutaneous Coronary Intervention in Patients With Atrial Fibrillation: Findings From the CONNECT AF+PCI Study.

ABSTRACT:

Background

In patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI), selecting an antithrombotic regimen requires balancing risks of ischemic cardiac events, stroke, and bleeding.

Methods

We 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.

Results

The 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).

Conclusions

Approximately 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.

Project description:BackgroundAlthough triple antithrombotic therapy (TAT) is recommended in patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI), guidelines allow an option of dual antithrombotic therapy (DAT). This study assesses the everyday practice of 10 cardiology departments in antithrombotic therapy in AF patients undergoing PCI and its agreement with current guidelines.MethodsThis analysis included medical data of AF patients enrolled in the prospective, observational registry (The POLish Atrial Fibrillation-POL-AF) that underwent PCI [elective or due to acute coronary syndrome (ACS)].ResultsOf the 3,999 consecutive subjects included, a final analysis was performed on 359 patients that underwent PCI: 148 with urgent PCI due to ACSand 211 patients with elective PCI. Eighty patients in the ACS-group and 120 patients in the elective-PCI group were treated with TAT, although guidelines also allowed DAT. Of 316 patients treated with oral anticoagulants as a part of combination therapy, 275 were on non-vitamin K antagonist oral anticoagulant (NOAC). Reduced doses of NOAC were used in 74 patients treated with rivaroxaban, 60 patients with dabigatran, and 54 patients with apixaban. The proportion of patients treated with reduced NOAC doses adequately to the guidelines was 29%, 100%, and 33% for rivaroxaban, dabigatran, and apixaban, respectively. Inappropriate low doses of NOACs were used in 71% of subjects on rivaroxaban and 67% on apixaban.ConclusionsIn patients with AF undergoing PCI, NOACs are definitely preferred over vitamin-K antagonists (VKAs) in TAT/DAT, and an aggressive antithrombotic strategy with TAT is frequently chosen even if DAT is permissible by the guidelines. Label adherence of using reduced NOAC dose during combination therapy is not satisfactory for apixaban and rivaroxaban and probably results from too cautious an approach to the known indications for reduced therapy. The study is registered in the database Clinical Trials-NCT04419012.

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:BackgroundAntithrombotic therapy for patients with atrial fibrillation undergoing percutaneous coronary intervention is facing major treatment problems in clinical practice.MethodsWe firstly conducted a Bayesian network meta-analysis to study the safety and efficacy of different antithrombotic regimens. Only randomized controlled trials from PubMed, Web of Science, Cochrane Central Register of Controlled Trials, Embase, and China National Knowledge Infrastructure were included in our study. The Bayesian random-effects model was used in this study. The primary safety and efficacy outcomes were major bleeding according to the criteria of Thrombolysis In Myocardial Infarction (TIMI) and trial-defined major adverse cardiovascular events, respectively. The secondary safety outcomes were combined TIMI major and minor bleeding, trial-defined primary bleeding events, and intracranial hemorrhage. The secondary efficacy outcomes were all-cause or cardiovascular mortality, myocardial infarction, stroke, stent thrombosis, and hospitalization.ResultsTotal of 11,532 patients from the five randomized controlled trials were analyzed, of whom 8,426 were male. Compared with vitamin K antagonist (VKA) plus P2Y12 inhibitor, the odds ratios (95% credible intervals) for TIMI major bleeding were 1.70 (0.77-3.80) for VKA plus dual antiplatelet therapy (DAPT), 1.20 (0.30-4.60) for rivaroxaban plus P2Y12 inhibitor, 1.00 (0.25-3.90) for rivaroxaban plus DAPT, 0.76 (0.21-2.80) for dabigatran plus P2Y12 inhibitor, 0.71 (0.25-2.10) for apixaban plus P2Y12 inhibitor, 1.40 (0.52-3.80) for apixaban plus DAPT, and 1.00 (0.27-4.00) for edoxaban plus P2Y12 inhibitor. For trial-defined major adverse cardiovascular events, compared with VKA plus P2Y12 inhibitor, the odds ratios (95% credible intervals) were 1.10 (0.61-2.00) for VKA plus DAPT, 1.20 (0.45-3.70) for rivaroxaban plus P2Y12 inhibitor, 1.10 (0.38-3.20) for rivaroxaban plus DAPT, 1.10 (0.43-3.10) for dabigatran plus P2Y12 inhibitor, 1.00 (0.47-2.20) for apixaban plus P2Y12 inhibitor, 0.99 (0.46-2.20) for apixaban plus DAPT, and 1.20 (0.43-3.40) for edoxaban plus P2Y12 inhibitor. Apixaban plus P2Y12 inhibitor was the highest-ranking of safety outcomes and VKA plus P2Y12 inhibitor was the highest-ranking of efficacy outcomes other than trial-defined major adverse cardiovascular events.ConclusionApixaban plus P2Y12 inhibitor seems to be linked with fewer bleeding complications while retaining antithrombotic efficacy. Moreover, for most efficacy indicators, the ranking of VKA plus P2Y12 inhibitor is still very high.Systematic review registration[www.crd.york.ac.uk/prospero/], identifier [CRD42020149894].
