Atrial fibrillation is an abnormal heart rhythm that can cause stroke, heart failure, heart attack, chronic kidney disease, dementia, and death.

Atrial fibrillation is classified as paroxysmal (intermittent episodes lasting 7 days or less), persistent (lasting more than 7 days), long-standing persistent (lasting more than 1 year), or permanent.1

In the US, atrial fibrillation affects about 10.55 million people and is more common among men than women. Other risk factors include older age, smoking, high blood pressure, diabetes, heart disease, high alcohol consumption, sleep apnea, an overactive thyroid gland, and possibly genetic factors.

Background: The optimal long-term antithrombotic strategy in patients with atrial fibrillation (AF) and stable coronary artery disease (CAD) remains uncertain. Individual randomized controlled trials (RCTs) had variations in their reported results and were not powered for effectiveness outcomes.

Objectives: This study aimed to pool the results of RCTs comparing the effectiveness and safety of oral anticoagulation (OAC) monotherapy vs OAC plus single antiplatelet therapy (SAPT) in patients with AF and stable CAD.

Methods: We systematically searched PubMed, Embase, and ClinicalTrials.gov until September 09, 2024. The primary effectiveness outcome was a composite of myocardial infarction, ischemic stroke, systemic embolism, or death. The primary safety outcome was major bleeding. We obtained unpublished results from principal investigators of the included RCTs, as needed, to calculate pooled HRs and 95% CIs and to perform prespecified subgroup analyses.

Results: Among 690 screened records, 4 RCTs with 4,092 randomized patients were included (2 using edoxaban, 1 using rivaroxaban, and 1 using any oral anticoagulant; mean age 73.9 years, 20.1% women). The median follow-up durations ranged from 12 to 30 months (overall estimated weighted mean follow-up of 21.9 months). There were no statistically significant differences between OAC monotherapy vs OAC plus SAPT in the primary effectiveness outcome (7.3% vs 8.2%; HR: 0.90; 95% CI: 0.72-1.12), myocardial infarction (1.0% vs 0.7%; HR: 1.51; 95% CI: 0.75-3.04), ischemic stroke (1.9% vs 2.1%; HR: 0.89; 95% CI: 0.57-1.37), all-cause death (4.2% vs 5.3%; HR: 0.94; 95% CI: 0.49-1.80), or cardiovascular death (2.4% vs 3.0%; HR: 0.79; 95% CI: 0.54-1.15). OAC monotherapy was associated with a lower risk of major bleeding than OAC plus SAPT (3.3% vs 5.7%; HR: 0.59; 95% CI: 0.44-0.79). Subgroup analyses did not show significant interactions for effectiveness but suggested that the magnitude of bleeding reduction may be greater among men (Pinteraction = 0.03) and among patients with diabetes mellitus (Pinteraction = 0.04).

Conclusions: In patients with AF and stable CAD, OAC monotherapy, compared with OAC plus SAPT, was not associated with a statistically significant increased risk of ischemic events but resulted in a significantly reduced risk of bleeding.

Importance: In the US, approximately 10.55 million adults have atrial fibrillation (AF). AF is associated with significantly increased risk of stroke, heart failure, myocardial infarction, dementia, chronic kidney disease, and mortality.

Observations: Symptoms of AF include palpitations, dyspnea, chest pain, presyncope, exertional intolerance, and fatigue, although approximately 10% to 40% of people with AF are asymptomatic. AF can be detected incidentally during clinical encounters, with wearable devices, or through interrogation of cardiac implanted electronic devices. In patients presenting with ischemic stroke without diagnosed AF, an implantable loop recorder (ie, subcutaneous telemetry device) can evaluate patients for intermittent AF. The 2023 American College of Cardiology (ACC)/American Heart Association (AHA)/American College of Clinical Pharmacy (ACCP)/Heart Rhythm Society (HRS) Guideline writing group proposed 4 stages of AF evolution: stage 1, at risk, defined as patients with AF-associated risk factors (eg, obesity, hypertension); stage 2, pre-AF, signs of atrial pathology on electrocardiogram or imaging without AF; stage 3, the presence of paroxysmal (recurrent AF episodes lasting ≤7 days) or persistent (continuous AF episode lasting >7 days) AF subtypes; and stage 4, permanent AF. Lifestyle and risk factor modification, including weight loss and exercise, to prevent AF onset, recurrence, and complications are recommended for all stages. In patients with estimated risk of stroke and thromboembolic events of 2% or greater per year, anticoagulation with a vitamin K antagonist or direct oral anticoagulant reduces stroke risk by 60% to 80% compared with placebo. In most patients, a direct oral anticoagulant, such as apixaban, rivaroxaban, or edoxaban, is recommended over warfarin because of lower bleeding risks. Compared with anticoagulation, aspirin is associated with poorer efficacy and is not recommended for stroke prevention. Early rhythm control with antiarrhythmic drugs or catheter ablation to restore and maintain sinus rhythm is recommended by the 2023 ACC/AHA/ACCP/HRS Guideline for some patients with AF. Catheter ablation is first-line therapy in patients with symptomatic paroxysmal AF to improve symptoms and slow progression to persistent AF. Catheter ablation is also recommended for patients with AF who have heart failure with reduced ejection fraction (HFrEF) to improve quality of life, left ventricular systolic function, and cardiovascular outcomes, such as rates of mortality and heart failure hospitalization.

Conclusions and relevance: AF is associated with increased rates of stroke, heart failure, and mortality. Lifestyle and risk factor modification are recommended to prevent AF onset, recurrence, and complications, and oral anticoagulants are recommended for those with an estimated risk of stroke or thromboembolic events of 2% or greater per year. Early rhythm control using antiarrhythmic drugs or catheter ablation is recommended in select patients with AF experiencing symptomatic paroxysmal AF or HFrEF.

Approach to atrial fibrillation: Essentials for primary care

RPR Commentary: It looks like catheter ablation is becoming the preferred treatment for many patients with atrial fibrillation for a variety of reasons including dementia prevention. James W. Mold, MD, MPH

Free full text

View

Background: Atrial fibrillation (AF) has consistently been associated with a higher risk of incident dementia. Observational evidence has suggested catheter ablation may be associated with a lower risk of dementia in patients with AF, but further research is needed. The objectives of this study were to use a global health research network to examine associations between catheter ablation, incident dementia and mortality in older adults with AF, and amongst subgroups by age, sex, co-morbidity status, and oral anticoagulant use.

Methods: The research network primarily included healthcare organizations in the United States. This network was searched on 28th September 2022 for patients aged ≥65 years with a diagnosis of AF received at least 5 years prior to the search date. Cox proportional hazard models were run on propensity-score matched cohorts.

Results: After propensity score matching, 20,746 participants (mean age 68 years; 59% male) were included in each cohort with and without catheter ablation. The cohorts were well balanced for age, sex, ethnicity, co-morbidities, and cardiovascular medications received. The risk of dementia was significantly lower in the catheter ablation cohort (Hazard Ratio 0.52, 95% confidence interval: 0.45-0.61). The catheter ablation cohort also had a lower risk of all-cause mortality (Hazard Ratio 0.58, 95% confidence interval: 0.55-0.61). These associations remained in subgroup analyses in individuals aged 65-79 years, ≥80 years, males, females, participants who received OACs during follow-up, participants with paroxysmal and non-paroxysmal AF, and participants with and without hypertension, diabetes mellitus, ischemic stroke, chronic kidney disease and heart failure, including heart failure with preserved ejection fraction and heart failure with reduced ejection fraction.

Conclusion: The observed lower risk of dementia and mortality with catheter ablation could be an important consideration when determining appropriate patient-centered rhythm control strategies for patients with AF. Further studies including data on the success of ablation are required.

Objective: To support family physicians in preventing atrial fibrillation (AF) in patients at risk and in identifying and managing those with established AF; and to summarize key recommendations for ideal screening and care of patients.

Sources of information: The 2020 Canadian Cardiovascular Society and Canadian Heart Rhythm Society comprehensive guidelines for the management of AF, based on current evidence and clinical experience related to AF.

Main message: Atrial fibrillation, which is estimated to affect at least 500,000 Canadians, is associated with high risks of stroke, heart failure, and death. Primary care clinicians occupy a central role in the management of this chronic condition, focusing on the challenges of preventing AF and identifying, diagnosing, treating, and following patients with AF. Evidence-based guidelines that provide optimal management strategies have been published by the Canadian Cardiovascular Society and Canadian Heart Rhythm Society to assist in these tasks. Messages critical to primary care are offered to support effective knowledge translation.

Conclusion: Most patients with AF can be managed effectively in primary care. Family physicians not only play an important role in ensuring patients with AF receive timely diagnoses, but they are also key to providing initial and ongoing care, especially in patients with comorbid conditions.

Outcomes Associated With Oral Anticoagulants Plus Antiplatelets in Patients With Newly Diagnosed Atrial Fibrillation

Evidence-based guidance for evaluation and management of patients with suspected transient ischemic attack. James W. Mold, MD, MPH

Free full text

View

Patients with suspected cerebral ischemia should be urgently assessed to distinguish between transient ischemic attack (TIA), minor stroke or mimics such as migraine, seizure, vertigo or syncope.

The Canadian TIA Score can be used to determine risk for early subsequent stroke in patients with a suspected TIA or minor stroke.

All patients with TIA or minor stroke should undergo urgent electrocardiography and computed tomography of the head.

Clinicians should order early vascular imaging for patients at moderate or high risk of subsequent stroke; urgent revascularization should be considered if there is more than 50% arterial stenosis congruent with symptom presentation.

Clinicians should prescribe dual antiplatelet drugs for high-risk patients, single antiplatelet agents for low-risk patients or direct oral anticoagulants for patients with atrial fibrillation.

All patients with TIA or minor stroke should be counselled about modifiable lifestyle factors (including smoking cessation), be treated with statins and take steps toward optimizing blood pressure, including treatment with antihypertensive drugs, if necessary.

IMPORTANCE:

Patients with nonvalvular atrial fibrillation at risk of stroke should receive oral anticoagulants (OAC). However, approximately 1 in 8 patients in the Global Anticoagulant Registry in the Field (GARFIELD-AF) registry are treated with antiplatelet (AP) drugs in addition to OAC, with or without documented vascular disease or other indications for AP therapy.

OBJECTIVE:

To investigate baseline characteristics and outcomes of patients who were prescribed OAC plus AP therapy vs OAC alone.

DESIGN, SETTING, AND PARTICIPANTS:

Prospective cohort study of the GARFIELD-AF registry, an international, multicenter, observational study of adults aged 18 years and older with recently diagnosed nonvalvular atrial fibrillation and at least 1 risk factor for stroke enrolled between March 2010 and August 2016. Data were extracted for analysis in October 2017 and analyzed from April 2018 to June 2019.

EXPOSURE:

Participants received either OAC plus AP or OAC alone.

MAIN OUTCOMES AND MEASURES:

Clinical outcomes were measured over 3 and 12 months. Outcomes were adjusted for 40 covariates, including baseline conditions and medications.

RESULTS:

A total of 24 436 patients (13 438 [55.0%] male; median [interquartile range] age, 71 [64-78] years) were analyzed. Among eligible patients, those receiving OAC plus AP therapy had a greater prevalence of cardiovascular indications for AP, including acute coronary syndromes (22.0% vs 4.3%), coronary artery disease (39.1% vs 9.8%), and carotid occlusive disease (4.8% vs 2.0%). Over 1 year, patients treated with OAC plus AP had significantly higher incidence rates of stroke (adjusted hazard ratio [aHR], 1.49; 95% CI, 1.01-2.20) and any bleeding event (aHR, 1.41; 95% CI, 1.17-1.70) than those treated with OAC alone. These patients did not show evidence of reduced all-cause mortality (aHR, 1.22; 95% CI, 0.98-1.51). Risk of acute coronary syndrome was not reduced in patients taking OAC plus AP compared with OAC alone (aHR, 1.16; 95% CI, 0.70-1.94). Patients treated with OAC plus AP also had higher rates of all clinical outcomes than those treated with OAC alone over the short term (3 months).

CONCLUSIONS AND RELEVANCE:

This study challenges the practice of coprescribing OAC plus AP unless there is a clear indication for adding AP to OAC therapy in newly diagnosed atrial fibrillation.

Guidelines recommend oral anticoagulant (OAC) monotherapy without antiplatelet therapy (APT) in patients with nonvalvular atrial fibrillation (AF) with stable coronary artery disease (CAD) of >1 year after myocardial infarction or percutaneous coronary intervention. More evidences are required for the safety and efficacy of OAC monotherapy compared with OAC plus APT. PubMed, EMBASE, and Cochrane Database of Systematic Reviews were systematically searched up to February 2019. Nonrandomized studies and randomized clinical trials comparing OAC monotherapy with OAC plus single APT (SAPT) for patients with stable CAD and nonvalvular AF. The primary end point was major adverse cardiovascular events (composite of ischemic or thrombotic events) and secondary outcomes included major bleeding, stroke, all-cause death, and net adverse events (composite of ischemic, thrombotic, or bleeding events). From 6 trials, 8,855 patients were included. There was no significant difference in major adverse cardiovascular event in patients with AF treated using OAC plus SAPT compared with those treated with OAC monotherapy (hazard ratio [HR] 1.09; 95% confidence interval [CI] 0.92 to 1.29). OAC plus SAPT was associated with a significantly higher risk of major bleeding compared with OAC monotherapy (HR 1.61; 95% CI 1.38 to 1.87), as well as in terms of net adverse event (HR 1.21; 95% CI 1.02 to 1.43). There were no significant differences in rates of stroke and all-cause death. In conclusion, in this meta-analysis, OAC monotherapy and OAC plus SAPT treatment showed similar effectiveness, but OAC monotherapy was significantly associated with a lower risk of bleeding compared with OAC plus SAPT in patients with nonvalvular AF and stable CAD.

For those wanting to know more about the Watchman device and other approaches to left atrial appendage occlusion for prevention of stroke due to atrial fibrillation, this was the best recent review article I could find. James W. Mold, MD, MPH

View

Stroke continues to be a major cause of morbidity and mortality in atrial fibrillation (AF) patients. Oral anticoagulation (OAC) provides protection against stroke and peripheral embolization in AF but significant proportion of patients could not be started on anticoagulation because of bleeding complications. Left atrial appendage harbors clot in about 90% of nonvalvular AF. The advent of left atrial appendage occlusion (LAAO) techniques has provided these patients with alternative to OAC for stroke prophylaxis. Multiple LAAO devices are currently available with Watchman and Amulet being the most commonly used in clinical practice. Randomized studies are available for Watchman device only. Data on Amplatzer Cardiac Plug, Amulet and Lariat devices are limited by the paucity of randomized data. Long-term data on different LAAO techniques are showing promising results. Device related thrombosis continues to be a serious complication associated with LAAO. Future studies should look into comparative effectiveness between different LAAO techniques, optimal patient selection, risk of complications, and anticoagulant treatment after LAAO. This article aims to provide current available evidence on efficacy and safety of different LAAO devices and future prospective.
