Abstract
OBJECTIVE To undertake a systematic review and meta-analysis to assess the satisfaction of patients receiving nonvitamin K anticoagulants (NOACs), compared with vitamin K antagonists (VKAs). METHODS We searched CENTRAL, MEDLINE, Embase, and Clinicaltrials.gov for randomized controlled trials (RCTs) and observational studies. Two reviewers screened, extracted, and appraised data independently. We pooled data using a random-effects model. Outcome included treatment satisfaction, which was assessed by scores of Duke Anticoagulation Satisfaction Scale (DASS), Anticlot Treatment Scale (ACTS), Perception of Anticoagulant Treatment Questionnaire 2 (PACT-Q2), or Treatment Satisfaction Questionnaire for Medication version II (TSQM-VII) and their domains reported with 95% confidence intervals (95% CIs). We followed MOOSE and PRISMA guidelines. RESULTS We included four RCTs and 16 observational studies, enrolling 18,684 participants overall. Compared with VKAs, treatment with NOACs improved the ACTS Burdens score by 4.21 points (95% CI: 2.99-5.43, I 2 = 95%, combined n = 6,180), and ACTS Benefits by 0.49 points (95% CI: 0.18-0.81, I 2 = 85%, combined n = 6,171). Switching from VKAs to NOACs improved the ACTS Burdens score by 5.33 points (95% CI: 3.53-7.14, combined n = 3,097). Compared with VKAs, treatment with NOACs improved the TSQM-VII Global Satisfaction score by 6.86 points (95% CI: 3.00-10.73, combined n = 5,535). CONCLUSION In patients with nonvalvular atrial fibrillation or venous thromboembolism, NOAC treatment is associated with greater satisfaction compared with VKAs. The switch from VKAs to NOACs was associated with improved patients' satisfaction. These effects were largely due to a lower degree of treatment burden with NOAC treatment.

Abstract
Background and Purpose:
Atrial fibrillation (AF) is the leading cause of ischemic stroke. Preventive antithrombotic use, especially for anticoagulation, reduces the incidence of ischemic stroke in patients with AF. Using data from the nationwide multicenter stroke registry, we investigated the trends of preceding antithrombotic medication use in patients with acute ischemic stroke (AIS) with AF and its association with initial stroke severity and in-hospital outcomes.
Methods:
This study included 6786 patients with AIS with known AF before stroke admission across 39 hospitals between June 2008 and December 2018. We collected the data on antithrombotic medication use (no antithrombotic/antiplatelet/anticoagulant) preceding AIS. Initial stroke severity was measured using the National Institutes of Health Stroke Scale, and in-hospital outcome was determined by modified Rankin Scale score at discharge.
Results:
During the study period, anticoagulant use continued to increase. However, nearly one-third of patients with AIS with known AF did not receive antithrombotics before stroke. Initial National Institutes of Health Stroke Scale scores varied according to preceding antithrombotic therapy (
P
<0.001). It was higher in patients who did not receive antithrombotics than in those who received antiplatelets or anticoagulants (median National Institutes of Health Stroke Scale score: 8 versus 7 and 8 versus 6, respectively). Favorable outcome at discharge (modified Rankin Scale score, 0–2) was more prevalent in patients who received antiplatelets or anticoagulants (
P
<0.001). Use of antiplatelets (odds ratio, 1.23 [95% CI, 1.09–1.38]) and anticoagulants (odds ratio, 1.31 [95% CI, 1.15–1.50]) was associated with a mild initial neurological deficit (National Institutes of Health Stroke Scale score ≤5) in patients with AIS with AF.
Conclusions:
Throughout the study period, the proportion of patients taking anticoagulants increased among patients with AIS with known AF. However, a large portion of AF patients still did not receive antithrombotics before AIS. Furthermore, prehospitalization use of anticoagulants was associated with a significantly higher likelihood of a mild initial neurological deficit and favorable outcome at discharge.

Abstract
Background We evaluated the safety and effectiveness of the hybrid thoracoscopic endocardial epicardial ablation technique for the treatment of atrial fibrillation (AF) in obese versus non-obese patients. Methods Between January 2010 and January 2015, a cohort of 61 patients were retrospectively identified to undergo ablation of AF as a stand-alone procedure using a thoracoscopic, hybrid epicardial-endocardial technique. All patients underwent continuous 7-day Holter monitoring at 3, 6 months, 1 year and yearly thereafter. Results A total of 40% of the obese cohort had persistent or long-standing AF, compared to 54.9% of the non-obese cohort. There were no deaths or conversion to cardiopulmonary bypass required. At 3-year follow-up, 60% of the obese group were in sinus rhythm (SR) with no episode of AF, atrial flutter or atrial tachycardia lasting 30 s off anti-arrhythmic drugs. This was compared to 70.6% in the non-obese group, with no significant difference between the groups (P=0.468). For success rates on anti-arrhythmic drugs, this was 80% in the obese group compared to 86% in the non-obese group at 3-year follow-up (P=0.637). No patient died and no thromboembolic/bleeding events or procedure-related complications occurred during the follow-up. Conclusions In a retrospective cohort with approximately half with persistent or long-standing AF, thoracoscopic hybrid epicardial endocardial ablation proved to be equally effective and safe in obese versus non-obese patients. Current preliminary findings require further validation in multi-institutional prospective studies with larger sample sizes.

Patient-reported treatment satisfaction with oral rivaroxaban versus standard therapy in the treatment of acute symptomatic deep-vein thrombosis. Thromb Haemost 2017; 110:732-41.

Abstract
SummaryRivaroxaban, an oral, direct factor Xa inhibitor, has been approved for the treatment of deep-vein thrombosis (DVT) and pulmonary embolism (PE) and the prevention of recurrent DVT and PE as a fixed-dose, single-drug regimen that does not require initial heparinisation, routine coagulation monitoring or dose adjustment. This study evaluated patient-reported treatment satisfaction in EINSTEIN DVT - a large, open-label, randomised study that compared rivaroxaban with enoxaparin/ vitamin K antagonist (VKA) therapy in patients with acute symptomatic DVT without PE. As part of EINSTEIN DVT, a total of 1,472 patients in seven countries were asked to complete a new, validated measure of treatment satisfaction - the Anti-Clot Treatment Scale (ACTS) - at scheduled visits throughout 12 months of treatment. ACTS scores were compared between study groups in the intentionto- treat population. Patients reported greater satisfaction in the rivaroxaban group compared with the enoxaparin/VKA group, with higher mean ACTS scores across visits. Mean ACTS Burdens scores were 55.2 vs 52.6 (p<0.0001) in favour of rivaroxaban, equivalent to a moderate effect size of 0.42. The treatment effect was consistent over time, with the mean score difference ranging from 2.18 (month 2) to 3.18 (month 12). Overall mean ACTS Benefits scores were 11.7 vs 11.5 in favour of rivaroxaban (p=0.006). This was associated with a small overall effect size of 0.12. The improvement in ACTS Benefits for rivaroxaban became apparent at month 2 and subsequent visits. Rivaroxaban results in improved treatment satisfaction compared with enoxaparin/VKA among patients with DVT, particularly in reducing patient-reported anticoagulation burden.

Abstract
BACKGROUND Rivaroxaban has become an alternative to vitamin-K antagonists (VKA) for stroke prevention in non-valvular atrial fibrillation (AF) patients due to its favourable risk-benefit profile in the restrictive setting of a large randomized trial. However in the primary care setting, physician's motivation to begin with rivaroxaban, treatment satisfaction and the clinical event rate after the initiation of rivaroxaban are not known. METHODS Prospective data collection by 115 primary care physicians in Switzerland on consecutive nonvalvular AF patients with newly established rivaroxaban anticoagulation with 3-month follow-up. RESULTS We enrolled 537 patients (73±11years, 57% men) with mean CHADS2 and HAS-BLED-scores of 2.2±1.3 and 2.4±1.1, respectively: 301(56%) were switched from VKA to rivaroxaban (STR-group) and 236(44%) were VKA-naïve (VN-group). Absence of routine coagulation monitoring (68%) and fixed-dose once-daily treatment (58%) were the most frequent criteria for physicians to initiate rivaroxaban. In the STR-group, patient's satisfaction increased from 3.6±1.4 under VKA to 5.5±0.8 points (P<0.001), and overall physician satisfaction from 3.9±1.3 to 5.4±0.9 points (P<0.001) at 3months of rivaroxaban therapy (score from 1 to 6 with higher scores indicating greater satisfaction). In the VN-group, both patient's (5.4±0.9) and physician's satisfaction (5.5±0.7) at follow-up were comparable to the STR-group. During follow-up, 1(0.19%; 95%CI, 0.01-1.03%) ischemic stroke, 2(0.37%; 95%CI, 0.05-1.34%) major non-fatal bleeding and 11(2.05%; 95%CI, 1.03-3.64%) minor bleeding complications occurred. Rivaroxaban was stopped in 30(5.6%) patients, with side effects being the most frequent reason. CONCLUSION Initiation of rivaroxaban for patients with nonvalvular AF by primary care physicians was associated with a low clinical event rate and with high overall patient's and physician's satisfaction.

Patient self-management of oral anticoagulation with vitamin K antagonists in everyday practice: efficacy and safety in a nationwide long-term prospective cohort study. PLoS One 2014; 9:e95761. [PMID: 24748062 PMCID: PMC3991723 DOI: 10.1371/journal.pone.0095761] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2014] [Accepted: 03/30/2014] [Indexed: 12/20/2022] Open
Abstract
Patient self-management (PSM) of oral anticoagulation is under discussion, because evidence from real-life settings is missing. Using data from a nationwide, prospective cohort study in Switzerland, we assessed overall long-term efficacy and safety of PSM and examined subgroups. Data of 1140 patients (5818.9 patient-years) were analysed and no patient were lost to follow-up. Median follow-up was 4.3 years (range 0.2-12.8 years). Median age at the time of training was 54.2 years (range 18.2-85.2) and 34.6% were women. All-cause mortality was 1.4 per 100 patient-years (95% CI 1.1-1.7) with a higher rate in patients with atrial fibrillation (2.5; 1.6-3.7; p<0.001), patients>50 years of age (2.0; 1.6-2.6; p<0.001), and men (1.6; 1.2-2.1; p = 0.036). The rate of thromboembolic events was 0.4 (0.2-0.6) and independent from indications, sex and age. Major bleeding were observed in 1.1 (0.9-1.5) per 100 patient-years. Efficacy was comparable to standard care and new oral anticoagulants in a network meta-analysis. PSM of properly trained patients is effective and safe in a long-term real-life setting and robust across clinical subgroups. Adoption in various clinical settings, including those with limited access to medical care or rural areas is warranted.

Abstract
BACKGROUND We evaluated the safety and effectiveness of the hybrid thoracoscopic endocardial epicardial technique for the treatment of lone atrial fibrillation. METHODS Between 2009 and 2012, a cohort of 78 consecutive patients (median age 60.5 years, 77% male) underwent ablation of atrial fibrillation (AF) as a stand-alone procedure using a thoracoscopic, hybrid epicardial-endocardial technique. All patients underwent continuous 7-day Holter monitoring at 3 months, 6 months, 1 year and yearly thereafter. All patients reached 1-year follow-up. Median follow-up was 24 months [interquartile range 12-36]. RESULTS No death or conversion to cardiopulmonary bypass occurred. No patient demonstrated paralysis of the phrenic nerve. Overall, the incidence of perioperative complications was 8% (n=6). At the end of follow-up, sixty-eight patients (87%) were in sinus rhythm (SR) with no episode of AF, atrial flutter or atrial tachycardia lasting longer than 30 seconds and off antiarrhythmic drugs (ADD). Among patients with long-standing persistent AF, 15 (100%) were in SR and off AAD. Success rates were 82% (n=28) in persistent and 76% (n=22) in paroxysmal AF (P=0.08). No patient died and no thromboembolic/bleeding events or procedure-related complications occurred during the follow-up. CONCLUSIONS Thoracoscopic hybrid epicardial endocardial technique proved to be effective and safe in the treatment of LAF and to represent an important new suitable option to treat stand-alone AF. Our findings need to be confirmed by further larger studies.

Abstract
OBJECTIVES We investigated real-life oral anticoagulation (OAC) treatment after surgical ablation and examined its adherence to current recommendations. We also explored factors related to OAC use preoperatively and at follow-up. METHODS One hundred and fifteen patients with atrial fibrillation (AF) were evaluated during 12-month follow-up after surgery. Patients were divided into two categories according to the congestive heart failure, hypertension, age ≥75 years, diabetes and prior stroke [or transient ischaemic attack or thromboembolism] (CHADS2) score: 60 patients were assigned to the high-risk group (CHADS2 score ≥2) and 55 to the low-risk group (CHADS2 score ≤1). OAC use was defined as guideline adherent, undertreatment or overtreatment. RESULTS Baseline overall guideline adherence was 62%. OAC was underprescribed in high-risk patients and overprescribed in low-risk patients (both, P < 0.001). The only factor associated with OAC use after logistic regression analysis were age >75 years (P = 0.01) and preoperative AF > paroxysmal (P = 0.013). Overall guideline adherence at 12-month follow-up showed a trend towards a better adherence in the sinus rhythm (SR) subgroup (74% vs 55%, P = 0.02). OAC was underprescribed in high-risk patients and overprescribed in low-risk patients (both P < 0.001). After logistic regression analysis, preoperative OAC use (P = 0.007) and other indications for OAC (P = 0.01) were predictors of anticoagulation treatment. CONCLUSIONS Real-life OAC prescription in AF patients showed a moderate guideline adherence, with high-risk patients being undertreated and low-risk patients being overtreated. These findings stress the importance that antithrombotic treatment in patients undergoing AF surgery needs to be critically re-evaluated.

Abstract
BACKGROUND AND OBJECTIVE No study has been published that compared persistence and discontinuation of warfarin with other long-term medications in patients with atrial fibrillation (AF). The objective of this study was to evaluate persistence and discontinuation patterns in AF patients taking warfarin and other common long-term medications and identify predictors of persistence and discontinuation in this population. METHODS Patients with warfarin prescription within 3 months after AF hospitalization discharge and 12-month data before and after the first prescription were evaluated using administrative claims data (1 January 2005 - 31 December 2007). For comparison, persistence patterns for other long-term medications for treatment of hypertension, hyperglycemia, heart disease, and dyslipidemia, including once- (od) and twice- (bid) daily medications, were evaluated. Non-persistence was defined as the presence of a ≥60-day gap in medication use. Permanent discontinuation was defined as no use of the medication for ≥90 days until the end of the follow-up period. Multivariate analysis was conducted to identify predictors of warfarin non-persistence and discontinuation. RESULTS 28 384 patients with AF were identified; 16 036 (56.5%) had a warfarin prescription following AF hospitalization. 53.5% of warfarin users were persistent for at least 1 year, similar to other long-term medications commonly prescribed to the AF population (ranging between 45.2% and 61.3%). 42.6% of warfarin users permanently discontinued warfarin within 1 year, also consistent with the discontinuation rate of 32.9-52.0% of other long-term medications. Residence in the South and West regions of the US, history of cardiac dysrhythmias, and warfarin cost-sharing significantly decreased the likelihood of warfarin persistence and increased the likelihood of discontinuation, while older age, history of ischemic stroke, and warfarin use before hospitalization significantly increased warfarin persistence and decreased the likelihood of discontinuation. Adherence of od and bid medications was similar. CONCLUSION Persistence and discontinuation with warfarin in patients with AF is consistent with other long-term medications. Identifying factors associated with non-persistence and discontinuation with long-term medications can help in developing targeted adherence programs.

Abstract
Oral anticoagulant-associated intracerebral hemorrhage is increasing in incidence and is the most feared complication of therapy with vitamin K1 antagonists. Anticoagulant-associated intracerebral hemorrhage has a high risk of ongoing bleeding, death, or disability. The most important aspect of clinical management of anticoagulant-associated intracerebral hemorrhage is represented by urgent reversal of coagulopathy, decreasing as quickly as possible the international normalized ratio to values ≤1·4, preferably ≤1·2, together with life support and surgical therapy, when indicated. Protocols for anticoagulant-associated intracerebral hemorrhage emphasize the immediate discontinuation of anticoagulant medication and the immediate intravenous administration of vitamin K1 (mean dose: 10-20 mg), and the use of prothrombin complex concentrates (variable doses calculated estimate circulating functional prothrombin complex) or fresh-frozen plasma (15-30 ml/kg) or recombinant activated factor VII (15-120 μg/kg). Because of cost and availability, there is limited randomized evidence comparing different reversal strategies that support a specific treatment regimen. In this paper, we emphasize the growing importance of anticoagulant-associated intracerebral hemorrhage and describe options for acute coagulopathy reversal in this setting. Additionally, emphasis is placed on understanding current consensus-based guidelines for coagulopathy reversal and the challenges of determining best evidence for these treatments. On the basis of the available knowledge, inappropriate adherence to current consensus-based guidelines for coagulopathy reversal may expose the physician to medico-legal implications.

Factors affecting adherence to guidelines for antithrombotic therapy in elderly patients with atrial fibrillation admitted to internal medicine wards. Eur J Intern Med 2010; 21:516-23.

Abstract
INTRODUCTION Current guidelines for ischemic stroke prevention in atrial fibrillation or flutter (AFF) recommend Vitamin K antagonists (VKAs) for patients at high-intermediate risk and aspirin for those at intermediate-low risk. The cost-effectiveness of these treatments was demonstrated also in elderly patients. However, there are several reports that emphasize the underuse of pharmacological prophylaxis of cardio-embolism in patients with AFF in different health care settings. AIMS To evaluate the adherence to current guidelines on cardio-embolic prophylaxis in elderly (> 65 years old) patients admitted with an established diagnosis of AFF to the Italian internal medicine wards participating in REPOSI registry, a project on polypathologies/polytherapies stemming from the collaboration between the Italian Society of Internal Medicine and the Mario Negri Institute of Pharmacological Research; to investigate whether or not hospitalization had an impact on guidelines adherence; to test the role of possible modifiers of VKAs prescription. METHODS We retrospectively analyzed registry data collected from January to December 2008 and assessed the prevalence of patients with AFF at admission and the prevalence of risk factors for cardio-embolism. After stratifying the patients according to their CHADS(2) score the percentage of appropriateness of antithrombotic therapy prescription was evaluated both at admission and at discharge. Univariable and multivariable logistic regression models were employed to verify whether or not socio-demographic (age >80years, living alone) and clinical features (previous or recent bleeding, cranio-facial trauma, cancer, dementia) modified the frequency and modalities of antithrombotic drugs prescription at admission and discharge. RESULTS Among the 1332 REPOSI patients, 247 were admitted with AFF. At admission, CHADS(2) score was ≥ 2 in 68.4% of patients, at discharge in 75.9%. Among patients with AFF 26.5% at admission and 32.8% at discharge were not on any antithrombotic therapy, and 43.7% at admission and 40.9% at discharge were not taking an appropriate therapy according to the CHADS(2) score. The higher the level of cardio-embolic risk the higher was the percentage of antiplatelet- but not of VKAs-treated patients. At admission or at discharge, both at univariable and at multivariable logistic regression, only an age >80 years and a diagnosis of cancer, previous or active, had a statistically significant negative effect on VKAs prescription. Moreover, only a positive history of bleeding events (past or present) was independently associated to no VKA prescription at discharge in patients who were on VKA therapy at admission. If heparin was considered as an appropriate therapy for patients with indication for VKAs, the percentage of patients admitted or discharged on appropriate therapy became respectively 43.7% and 53.4%. CONCLUSION Among elderly patients admitted with a diagnosis of AFF to internal medicine wards, an appropriate antithrombotic prophylaxis was taken by less than 50%, with an underuse of VKAs prescription independently of the level of cardio-embolic risk. Hospitalization did not improve the adherence to guidelines.

Abstract
Thrombosis, the localized clotting of blood, occurs in both the arterial and venous circulation, and has a major impact on health outcomes. The primary etiology of myocardial infarctions, and approximately 80% of strokes, is acute arterial thrombosis. In combination this represents the most common cause of death in the Western world, while the third leading cause of cardiovascular-associated death is venous thromboembolism. An understanding of the pathogenic changes in the vessel wall and the blood that result in thrombosis is crucial for developing safer and more effective antithrombotic drugs. Dabigatran etexilate belongs to a new class of direct thrombin inhibitors. Following oral administration, dabigatran reaches peak plasma concentrations within 2 hours, shows linear pharmacokinetics, and a limited (but important) amount of direct drug interactions. Given once daily at 150 mg or 220 mg, it has proven to be competitive with enoxaparin in the prevention of venous thromboembolism after major orthopedic surgery, with a comparable safety profile. For stroke prevention in patients suffering from atrial fibrillation, dabigatran administered at a dose of 110 mg twice daily was associated with rates of stroke and systemic embolism that were similar to those associated with warfarin, as well as lower rates of hemorrhage. Dabigatran given at a dose of 150 mg twice daily, as compared with warfarin, was associated with lower rates of stroke and systemic embolism but similar rates of major hemorrhage. Oral bioavailability of dabigatran, together with a rapid onset and offset of action and predictable anticoagulation response, makes this newly available antithrombotic drug an attractive alternative to traditional anticoagulant therapies for numerous thrombosis-related indications.

Abstract
Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia. The prevalence of AF increases sharply in old age (prevalence approximately 10% among persons 80 years of age and older). The expected risk for ischemic stroke is increased five-fold by the presence of AF, primarily as a result of cardiogenic embolism. Multiple large-scale, randomized trials have been completed or are still underway to find optimal, efficacious, and relatively safe ways to reduce the risk of ischemic stroke and other systemic thromboembolic events related to AF. Antithrombotic strategies are accompanied by serious bleeding complications that threaten patients in need of medical stroke prevention. Treatment regimens for preventing thromboembolism in AF patients range from vitamin K antagonists such as warfarin or coumadins, antiplatelet drugs like aspirin or clopidogrel, to newly developed orally available antithrombotics like the direct thrombin inhibitor dabigatran, or the Factor Xa-inhibitor rivaroxaban. The available anticoagulant and antiplatelet drugs have different advantages and disadvantages. This review attempts to delineate the specific role of clopidogrel in patients with AF and at risk of stroke, taking into consideration new and ongoing trials in this important field of medical practice.
