Abstract
BACKGROUND Triple antithrombotic therapy (TAT), a combination of an oral anticoagulant and dual antiplatelet therapy (DAPT), is a key treatment for prevention of ischemic events in patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI). However, TAT is not extensively used because of the risk of bleeding. This study aimed to determine the utilization and influencing factors of TAT using real-world data in the non-vitamin K antagonist oral anticoagulants (NOACs) era. METHODS We analyzed National Inpatient Sample data compiled by the Health Insurance Review & Assessment Service (HIRA-NIS) from 2011 to 2020. Patients with AF who underwent PCI with stent implantation and with an increased stroke risk were selected as candidates for TAT therapy. Demographic and clinical factors associated with TAT use were investigated using the chi-squared test and the Student t-test, and influencing factors were identified using multiple logistic regression. RESULTS The TAT utilization rate steadily increased from 30.3% in 2011 to 65.4% in 2020 (Cochran-Armitage trend test: p < 0.001) with an average of 45.9%. Positive influencing factors for TAT use were identified as congestive heart failure, history of previous stroke/transient ischemic attack/thromboembolism, valvular heart disease, and year. Negative influencing factors included insurance type (medical aid or Patriots & Veterans Insurance), type of medical institution (general hospitals or primary medical institutions), and comorbidities such as renal disease, liver disease, and history of the previous hemorrhage. CONCLUSIONS The utilization of TAT following PCI among high-stroke risk AF patients steadily increased from 2011 to 2020, reaching 65.4% by the end of the study period. However, in 2020, a significant proportion of 29.4% of patients still received DAPT, indicating that many AF patients undergoing PCI did not receive adequate antithrombotic therapy.

Abstract
Background The management of atrial fibrillation and flutter (AF) patients undergoing percutaneous coronary intervention (PCI) has evolved rapidly in the past decade. We determine whether the publication of the 2016 Canadian Cardiovascular Society AF guidelines were associated with a shift in practice patterns. Methods Using Quebec provincial administrative database information for the period from 2010-2017, a retrospective cohort of patients with inpatient or outpatient coding for AF, who subsequently underwent PCI with placement of a coronary stent, was created and analyzed for the antithrombotic regimen received in the following year. Prescribing behavior was compared among 3 time periods (2010-2011, 2012-2015, 2016-2017), and use of antithrombotics was compared to guideline-predicted therapy using the χ2 test. Predictors of oral anticoagulation (OAC) prescription were identified using adjusted logistic regression. Results A total of 3740 AF patients undergoing PCI were included. The proportion of OAC prescription increased over time (2010-2011 = 51.4%; 2012-2015 = 54.3%; 2016-2017 = 56.6%; P = 0.13), with a significant increase in direct OAC prescription (P < 0.01). A substantial treatment gap in OAC prescription persisted after publication of the 2016 guidelines (56.6% observed vs 89.7% predicted; P < 0.01). Previous stroke, CHADS2 score, Charlson Comorbidity Index ≥ 4, and prior use of direct OAC or warfarin were predictors of being exposed to OAC claims; previous major bleeding, and low-dose acetylsalicylic acid or P2Y12 inhibitor use were predictors of not being exposed to OACs. Conclusion Expert guidance contributed to an increase in OAC prescription following PCI, but up to 2017, substantial further changes in practice patterns would have been required to achieve the recommended rates of OAC prescription.

Abstract
Background The management of atrial fibrillation and/or flutter (AF) patients requiring percutaneous coronary intervention (PCI) has evolved significantly. The Canadian Cardiovascular Society AF guidelines, last updated in 2020, seek to aid physicians in balancing both bleeding and thrombotic risks. Methods A tertiary academic centre registry of patients with AF who had PCI was examined for the antithrombotic therapy at discharge in 4 time periods (cohort 2010–2011; cohort 2014–2015; cohort 2017; cohort 2019). Discharge prescription patterns were compared among the cohorts, using the χ2 test. In addition, antithrombotic management in cohorts 2017 and 2019 were compared to guideline-expected therapy, using the χ2 test. Results A total of 576 AF patients undergoing PCI were included. Clinical and procedural characteristics were similar among cohorts, except for an increase in drug-eluting stent use in the most recent cohort (94% vs 99%; P = 0.04). The rate of oral anticoagulation increased over time (75% vs 89%; P < 0.01), driven primarily by an increase in direct oral anticoagulants prescription (63% vs 84%; P < 0.01). In contrast to previous cohorts, there was no significant difference between the observed and the guideline-expected anticoagulation rate in cohort 2019 (89% vs 94%; P = 0.23). Conclusions A combination of expert guidance and educational initiatives in the past decade contributed to dramatic changes in the management of patients with AF undergoing PCI.

Longitudinal Patterns in Antithrombotic Therapy in Patients with Atrial Fibrillation after Percutaneous Coronary Intervention in the Non-Vitamin K Oral Anticoagulant Era: A Nationwide Population-Based Study. J Clin Med 2021; 10:jcm10071505.

Abstract
We investigated whether longitudinal patterns in antithrombotic therapy have changed after the introduction of non-vitamin K oral anticoagulants (NOACs) in patients with atrial fibrillation (AF) who underwent percutaneous coronary intervention (PCI). Using a claims database of the Korean AF population who underwent PCI between 2012 and 2016 (n = 18,691), we analyzed prescription records of oral anticoagulants (OACs) and antiplatelets at 3-month intervals over 2 years after PCI. The study population was stratified (pre-NOAC, transition, and NOAC era) using time-periods of NOAC introduction in Korea and an expansion of reimbursement for NOAC in AF as indicators. The overall rates of OAC were low at baseline (24.9%, 26.9%, and 35.2% in pre-NOAC, transition, and NOAC era, respectively), contrary to high rates of dual antiplatelet therapy (DAPT) (73.3%, 71.4%, and 63.6%). However, OAC prescription rates were increased at 1-year (18.5%, 22.5%, and 31.6%), and 2-year follow-up (17.8%, 24.2%, and 31.8%) from pre-NOAC to NOAC era. In NOAC era, 63.5% of baseline OAC prescriptions comprised NOAC, of which 96.4% included triple therapy with DAPT. Over 2 years, we observed increasing rates of double therapy with a single antiplatelet (18.3% and 20.0% at 1- and 2-year follow-up) and OAC monotherapy (2.7% and 8.9% at 1- and 2-year follow-up).

Drug-eluting versus bare-metal stents for first myocardial infarction in patients with atrial fibrillation: A nationwide population-based cohort study. PLoS One 2020; 15:e0227571.

Abstract
BACKGROUND Acute myocardial infarction (AMI) complicates the clinical management of atrial fibrillation (AF) because coronary stenting may influence subsequent antithrombotic therapy. We investigated the use of a bare-metal stent (BMS) or a drug-eluting stent (DES) and associated outcomes in patients with pre-existing AF and first AMI undergoing percutaneous coronary intervention. METHODS AND RESULTS Patient records in this population-based study were retrospectively collected from the Taiwan National Health Insurance Research Database. Using propensity score matching (PSM), we used 1:2 ratio stratification into a DES group of 436 and a BMS group of 785 patients from 2007 to 2011. The mean follow-up of matched cohorts was 1.7 years. After PSM, DESs were associated with lower rates of cardiovascular death (7.8%, hazard ratio [HR] 0.58, 95% confidence interval [CI] 0.39-0.86 and 10.1%, HR 0.64, 95% CI 0.45-0.90) and primary composite outcome (35.1%, HR 0.76, 95% CI 0.63-0.92 and 48.2%, HR 0.81, 95% CI 0.69-0.96) than BMSs within the first year and at the end of follow-up. Although the greatest benefit from DESs, irrespective of the first- and second- generation DESs, implantation was observed within the first year only, this benefit was not observed in patients with diabetes, chronic kidney disease, or dialysis. CONCLUSIONS Use of DESs in AMI patients with pre-existing AF is associated with significantly lower rates of cardiovascular death and primary composite outcome within the first year follow-up. However, the effect is not apparent in patients with diabetes, chronic kidney disease or dialysis.

Abstract
BACKGROUND Clinicians must balance the risks of bleeding and thrombosis after percutaneous coronary intervention (PCI) in people with an indication for anticoagulation. The potential of non-vitamin K antagonists (NOACs) to prevent bleeding complications is promising, but evidence remains limited. OBJECTIVES To review the evidence from randomised controlled trials assessing the efficacy and safety of non-vitamin K antagonist oral anticoagulants (NOACs) compared to vitamin K antagonists post-percutaneous coronary intervention (PCI) in people with an indication for anticoagulation. SEARCH METHODS We identified studies by searching CENTRAL, MEDLINE, Embase, the Conference Proceedings Citation Index - Science and two clinical trials registers in February 2019. We checked bibliographies of identified studies and applied no language restrictions. SELECTION CRITERIA We searched for randomised controlled trials (RCT) that compared NOACs and vitamin K antagonists for people with an indication for anticoagulation who underwent PCI. DATA COLLECTION AND ANALYSIS Two review authors independently checked the results of searches to identify relevant studies, assessed each included study, and extracted study data. We conducted random-effects, pairwise analyses using Review Manager 5 and network meta-analyses (NMA) using the R package 'netmeta'. We ranked competing treatments by P scores, which are derived from the P values of all pairwise comparisons, and allow ranking of treatments on a continuous 0 to 1 scale. MAIN RESULTS We identified nine RCTs that met the inclusion criteria, but four were ongoing trials, and were not included in this analysis. We included five RCTs, with 8373 participants, in the NMA (two RCTs compared apixaban to a vitamin K antagonist, two RCTs compared rivaroxaban to a vitamin K antagonist, and one RCT compared dabigatran to a vitamin K antagonist). Very low- to moderate-certainty evidence suggests little or no difference between NOACs and vitamin K antagonists in death from cardiovascular causes (not reported in the dabigatran trial), myocardial infarction, stroke, death from any cause, and stent thrombosis. Apixaban (RR 0.85, 95% CI 0.77 to 0.95), high dose rivaroxaban (RR 0.86, 95% CI 0.74 to 1.00), and low dose rivaroxaban (RR 0.80, 95% CI 0.68 to 0.92) probably reduce the risk of recurrent hospitalisation compared with vitamin K antagonists. No studies looked at health-related quality of life. Very low- to moderate-certainty evidence suggests that NOACs may be safer than vitamin K antagonists in terms of bleeding. Both high dose dabigatran (RR 0.53, 95% CI 0.29 to 0.97), and low dose dabigatran (RR 0.38, 95% CI 0.21 to 0.70) may reduce major bleeding more than vitamin K antagonists. High dose dabigatran (RR 0.83, 95% CI 0.72 to 0.96), low dose dabigatran (RR 0.66, 95% CI 0.58 to 0.75), apixaban (RR 0,67 , 95% Cl 0.51 to 0.88), high dose rivaroxaban (RR 0.66, 95% CI 0.52 to 0.83), and low dose rivaroxaban (RR 0.71, 95% CI 0.57 to 0.88) probably reduce non-major bleeding more than vitamin K antagonists. The results from the NMA were inconclusive between the different NOACs for all primary and secondary outcomes. AUTHORS' CONCLUSIONS Very low- to moderate-certainty evidence suggests no meaningful difference in efficacy outcomes between non-vitamin K antagonist oral anticoagulants (NOAC) and vitamin K antagonists following percutaneous coronary interventions (PCI) in people with non-valvular atrial fibrillation. NOACs probably reduce the risk of recurrent hospitalisation for adverse events compared with vitamin K antagonists. Low- to moderate-certainty evidence suggests that dabigatran may reduce the rates of major and non-major bleeding, and apixaban and rivaroxaban probably reduce the rates of non-major bleeding compared with vitamin K antagonists. Our network meta-analysis did not show superiority of one NOAC over another for any of the outcomes. Head to head trials, directly comparing NOACs against each other, are required to provide more certain evidence.

Abstract
Background The management of atrial fibrillation and flutter (AF) patients undergoing percutaneous coronary intervention (PCI) has undergone a rapid recent evolution. In 2016, the Canadian Cardiovascular Society (CCS) published expert recommendations to help guide clinicians in balancing bleeding and thrombotic risks in these patients. Hypothesis Antithrombotic regimen prescriptions for AF patients undergoing PCI evolved after the publication of the 2016 CCS AF guidelines. Methods A prospective cohort of AF patients undergoing PCI with placement of a coronary stent from a single tertiary academic center was analyzed for the recommended antithrombotic regimen at discharge. Prescribing behavior was compared between three time periods (Cohort A [2010‐2011]; Cohort B [2014‐2015]; Cohort C [2017]) using the χ2 test. In addition, antithrombotic management in Cohorts B and C were compared to guideline‐recommended therapy. Results A total of 459 patients with AF undergoing PCI were identified. Clinical and procedural characteristics were similar between cohorts, with the exception of an increase in drug‐eluting stent (DES) use over time (P < .01). Overall, the rate of oral anticoagulation (OAC) increased over time (P < .01), associated with an increase in nonvitamin K OAC prescription (P < .01) and a concomitant decrease in vitamin K antagonist prescription (P < .01). Despite this, the overall rate of anticoagulation remains below what would be predicted with perfect guideline compliance (75% vs 94%, P < .01). Conclusion There has been a dramatic shift in clinical practice for AF patients requiring PCI, with increases in prescription of OAC even in the context of an increase in the use of DES. However, room for further practice optimization still exists.

Abstract
Atrial fibrillation (AF) is the most common chronic cardiac arrhythmia with an increasing prevalence over time mainly because of population aging. It is well established that the presence of AF increases the risk of stroke, heart failure, sudden death, and cardiovascular morbidity. In the last two decades several reports have shown an association between AF and cognitive function, ranging from impairment to dementia. Ischemic stroke linked to AF is a well-known risk factor and predictor of cognitive decline. In this clinical scenario, the risk of stroke might be reduced by oral anticoagulation. However, recent data suggest that AF may be a predictor of cognitive impairment and dementia also in the absence of stroke. Cerebral hypoperfusion, reduced brain volume, microbleeds, white matter hyperintensity, neuroinflammation, and genetic factors have been considered as potential mechanisms involved in the pathogenesis of AF-related cognitive dysfunction. However, a cause-effect relationship remains still controversial. Consequently, no therapeutic strategies are available to prevent AF-related cognitive decline in stroke-free patients. This review will analyze the potential mechanisms leading to cognitive dysfunction in AF patients and examine the available data on the impact of a sinus rhythm restoration and maintenance strategy in reducing the risk of cognitive decline.

Abstract
Background and Purpose- The optimal antithrombotic strategy to balance thromboembolic and bleeding events, especially acute stroke, for patients with atrial fibrillation following coronary stenting remains a matter of debate. We conducted a network meta-analysis to identify the antithrombotic regimen associated with the lowest rate of bleeding and thromboembolic events in atrial fibrillation after coronary stenting. Methods- PubMed, Scopus, and Cochrane Central were searched for randomized controlled trials and observational studies of patients with atrial fibrillation after coronary stenting. The outcomes of interest were stroke, myocardial infarction, major adverse cardiac events, mortality, and major bleeding. A network meta-analysis was performed comparing the available antithrombotic regimens in the literature. Results- Three randomized and 15 observational studies were included, with a total of 23 478 participants. Median follow-up was 2 years. Network meta-analysis demonstrated that vitamin K antagonist plus single antiplatelet therapy or direct-acting oral anticoagulant plus single antiplatelet therapy were the most effective regimens in preventing stroke. Direct-acting oral anticoagulant regimens were associated with lower major bleeding rates than vitamin K antagonist regimens. Regimens with dual antiplatelet therapy were associated with lower rates of myocardial infarction. Vitamin K antagonist plus dual antiplatelet therapy was associated with a lower mortality and low-dose direct-acting oral anticoagulants with decreased major cardiovascular adverse events. Conclusions- Direct-acting oral anticoagulant regimens were associated with less major bleeding and major cardiovascular adverse events, but vitamin K antagonists were associated with decreased mortality and stroke. These results suggest that the decision of antithrombotic therapy in patients with atrial fibrillation after percutaneous coronary intervention needs to be individualized.

Safety and Efficacy of Triple Antithrombotic Therapy with Dabigatran versus Vitamin K Antagonist in Atrial Fibrillation Patients: A Pilot Study. BIOMED RESEARCH INTERNATIONAL 2019; 2019:5473240. [PMID: 30895193 PMCID: PMC6393928 DOI: 10.1155/2019/5473240] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/30/2018] [Accepted: 01/13/2019] [Indexed: 01/22/2023]
Abstract
Background Combination of dual antiplatelet (DAPT) and oral anticoagulation therapy is required to decrease cardioembolic stroke and stent thrombosis risk in patients with atrial fibrillation (AF) and acute coronary syndrome (ACS). We compared the safety and efficacy of dabigatran etexilate with vitamin K antagonist (VKA), in combination with DAPT (aspirin plus clopidogrel) treatment in AF patients who underwent percutaneous coronary intervention (PCI) with stenting for ACS. Methods Consecutive nonvalvular AF patients who received twice-daily dabigatran 110 mg (n = 389) or VKA (n = 510) and DAPT were included. Primary endpoints were major bleeding (safety) and the composite of ischemic stroke, systemic embolism, and myocardial infarction (efficacy). The secondary efficacy endpoint was hospitalization for cardiovascular disease. Results After propensity score matching, comparative treatment groups comprised 175 dabigatran recipients and 175 VKA recipients. The cumulative incidence of major bleeding was lower in the dabigatran group (2.3%) compared with the VKA group (10.3%) with a hazard ratio (HR) of 4.81 [95% confidence interval (CI) 1.6-14.2, p < 0.005]. The cumulative incidence of thromboembolic events with dabigatran was slightly higher (8.0%) than with VKA (6.85%), but not statistically significantly so (0.8, 0.39-1.8; p = 0.6). Cumulative incidence of hospitalization for cardiovascular disease was lower with dabigatran (10.3%) compared with VKA (20.6%) treatment (2.2, 1.25-3.8; p < 0.006). Conclusion Dabigatran at the dose used for stroke prevention appears safer than VKA and maintains a similar efficacy profile, when used with DAPT, in AF patients who have undergone PCI with stenting for ACS.

Poor outcomes associated with antithrombotic undertreatment in patients with atrial fibrillation attending Gondar University Hospital: a retrospective cohort study. Thromb J 2018; 16:22. [PMID: 30237753 PMCID: PMC6142404 DOI: 10.1186/s12959-018-0177-1] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2018] [Accepted: 07/12/2018] [Indexed: 11/29/2022] Open
Abstract
BACKGROUND Atrial fibrillation (AF) is a major risk factor for stroke as it increases the incidence of stroke nearly fivefold. Antithrombotic treatment is recommended for the prevention of stroke in AF patients. However, majorly due to fear of risk of bleeding, adherence to recommendations is not observed. The aim of this study was to investigate the impact of antithrombotic undertreatment, on ischemic stroke and/or all-cause mortality in patients with AF. METHODS A retrospective cohort study was conducted from January 7, 2017 to April 30 2017 using medical records of patients with AF attending Gondar University Hospital (GUH) between November 2012 and September 2016. Patients receiving appropriate antithrombotic management and those on undertreatment, were followed for development of ischemic stroke and/or all-cause mortality. Kaplan-Meier and a log-rank test was used to plot the survival analysis curve. Cox regression was used to determine the predictors of guideline-adherent antithrombotic therapy. RESULTS The final analysis included 159 AF patients with a median age of 60 years. Of these, nearly two third (64.78%) of patients were receiving undertreatment for antithrombotic medications. Upon multivariate analysis, history of ischemic stroke/transient ischemic attack (TIA) was associated with lower incidence of antithrombotic undertreatment. A significant increase (HR: 8.194, 95% CI: 2.911-23.066)] in the incidence of ischemic stroke and/or all-cause mortality was observed in patients with undertreatment. Up-on multivariate analysis, only increased age was associated with a statistically significant increase incidence of ischemic stroke and/or all-cause mortality, while only history of ischemic stroke/TIA was associated with a decrease in the risk of ischemic stroke and/or all-cause mortality. CONCLUSION Adherence to antithrombotic guideline recommendations was found to be crucial in reducing the incidence of ischemic stroke and/or all-cause mortality in patients with AF without increasing the risk of bleeding. However, undertreatment to antithrombotic medications was found to be high (64.78%) and was associated with poorer outcomes in terms of ischemic stroke and/or all-cause mortality. Impact on practice: This research highlighted the magnitude of antithrombotic undertreatment and its impact on ischemic stroke and/or all-cause mortality in patients with AF. This article has to alert prescribers to routinely evaluate AF patients' risk for ischemic stroke and provide appropriate interventions based on guideline recommendations.

Abstract
BACKGROUND Antithrombotic management of patients with atrial fibrillation (AF) requiring percutaneous coronary intervention (PCI) is highly variable; limited evidence-based guidelines exist to influence practice. HYPOTHESIS Patient characteristics and availability of novel drugs may have contributed to practice variability. METHODS We undertook an international multicenter retrospective registry of AF patients treated with PCI. The primary measures of interest were antiplatelet and OAC prescriptions at discharge. We compared temporal trends between Prior (2010-2012) and Recent (2013-2015) cohorts and investigated variables associated with OAC prescription. RESULTS We identified 488 cases (140 Prior, 348 Recent). Median CHADS2 and HAS-BLED scores were 2 (IQR, 1-3) and 2 (IQR, 2-3). Clinical characteristics were similar between cohorts, with high (85%) prevalence of ACS. More patients in the Recent cohort, compared with Prior, received OAC (56.9% vs 44.3%; P = 0.01) and NOAC (27.3% vs 3.6%; P < 0.01) at baseline. Triple therapy at discharge was not different between the cohorts. Clinical presentation with ACS and consequent use of potent P2Y12 inhibitors were associated with reduced odds of OAC prescription at discharge (OR: 0.57, P = 0.045 and OR: 0.38, P = 0.023, respectively). CONCLUSIONS Despite little change over time in clinical characteristics of AF patients undergoing PCI, significantly more patients received OAC at presentation. However, triple therapy was not more frequent in the Recent cohort, and ACS presentation was associated with lack of OAC at discharge. We underscore the need for trial evidence and use of updated guidelines to assist clinicians in balancing ischemic and bleeding risks.
