Abstract
Novel oral anticoagulants (NOACs) are preferentially recommended in patients with nonvalvular atrial fibrillation (AF) for stroke prevention over vitamin K antagonists (VKAs). However, the evidence regarding the efficacy and safety of NOACs versus VKAs after transcatheter aortic valve implantation (TAVI) in patients with AF is very rare. Pubmed, Embase, Web of science, and Cochrane Databases were searched for eligible studies published before May 19, 2022. A total of 11 studies were included in this meta-analysis involving 27 107 patients. Regarding primary outcomes, there were no differences between NOACs and VKAs in all-cause mortality (RR: 0.84, 95% CI: (0.69, 1.02)) and stroke (RR: 1.00, 95% CI: (0.85, 1.19)). With respect to secondary outcomes, NOACs were associated with reduced incidence of bleeding (RR: 0.77, 95% CI: (0.71, 0.83)) and intracranial bleeding (RR: 0.57, 95% CI: (0.39, 0.83)), whereas no significant differences were found in major or life-threatening bleeding (RR: 0.98, 95% CI: (0.82, 1.17)) and myocardial infarction (RR: 1.37, 95% CI: (0.83, 2.26)). Our meta-analysis revealed the safety and efficacy of NOACs may be superior to VKAs in AF patients undergoing TAVI.

Abrignani MG, Lombardo A, Braschi A, Renda N, Abrignani V, Lombardo RM. Time trends in antithrombotic therapy prescription patterns: Real-world monocentric study in hospitalized patients with atrial fibrillation. World J Cardiol 2022; 14:576-598. [PMID: 36483763 PMCID: PMC9724000 DOI: 10.4330/wjc.v14.i11.576] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/13/2022] [Revised: 07/04/2022] [Accepted: 10/28/2022] [Indexed: 11/24/2022] Open
Abstract
BACKGROUND Since 2010, the European Society of Cardiology has extended prescription criteria for oral antithrombotic therapy (OAT) in atrial fibrillation (AF). Direct oral anticoagulants (DOACs) were upgraded from an IIAa recommendation in 2012 to an IA in 2016. In real-world scenarios, however, OAC prescription is still suboptimal, mainly for DOACs.
AIM To evaluate OAT temporal prescription patterns in a cohort of patients hospitalized with AF in a Cardiology Department.
METHODS A retrospective observational study was conducted on a cohort of hospitalized patients in a secondary setting (Trapani, Italy) from 2010 to 2021 with AF as the main or secondary diagnosis. For 4089 consecutive patients, the variables extracted from the Cardiology department database were: Sex, age, time of hospitalization, antithrombotic therapy (warfarin, acenocoumarol, apixaban, dabigatran, edoxaban, rivaroxaban, aspirin, clopidogrel, other antiplatelet agents, low molecular weight heparin, and fondaparinux), diagnosis at discharge and used resources. Basal features are presented as percentage values for categorized variables and as mean +/- SD for categorized once.
RESULTS From January 1st, 2010 to October 6th, 2021, 25132 patients were hospitalized in our department; 4089 (16.27%, mean age 75.59+/-10.82) were discharged with AF diagnosis; of them, 2245 were males (54.81%, mean age 73.56+/-11.45) and 1851 females (45.19%, mean age 78.06+/-9.47). Average length of stay was 5.76+/-4.88 days; 154 patients died and 88 were moved to other Departments/Structures. AF was the main diagnosis in 899 patients (21.94%). The most frequent main diagnosis in patients with AF was acute myocardial infarction (1973 discharges, 48.19%). The most frequent secondary cardiac diagnosis was chronic coronary syndrome (1864 discharges, 45.51%), and the most frequent secondary associated condition was arterial hypertension (1010 discharges, 24.66%). For the analysis of antithrombotic treatments, the final sample included 3067 patients, after excluding in-hospital deaths, transferred out or self-discharged patients, as well as discharges lacking indications for prescribed treatments. OAC treatment increased significantly (35.63% in 2010-2012 vs 61.18% in 2019-2021, +25.55%, P < 0.0001), in spite of any antiplatelet agent use. This rise was due to increasing use of DOACs, with or without antiplatelet agents, from 3.04% in 2013-2015 to 50.06% in 2019-2021 (+47.02%, P < 0.0001) and was greater for factor Xa inhibitors, especially apixaban. In addition, treatment with a vitamin K antagonist, in spite of any antiplatelet agent use, decreased from 35.63% in 2010-2012 to 11.12% in 2019-2021 (-24.48%, P < 0.0001), as well as any antiplatelet therapy, alone or in double combination, (49.18% in 2010-2012 vs 34.18% in 2019-2021, -15.00%, P < 0.0001); and patients not receiving antithrombotic therapy declined with time (14.58% in 2010-2012 vs 1.97% in 2021, P < 0.0001).
CONCLUSION Real-world patients with AF are elderly and affected by cardiovascular and non-cardiovascular diseases. The percentage of patients on OAT and DOACs increased. These data suggest a slow, gradual guidelines implementation process.

BMC Cardiovasc Disord 2022; 22:481. [DOI: 10.1186/s12872-022-02910-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2022] [Accepted: 10/21/2022] [Indexed: 11/13/2022] Open
Abstract
Abstract
Background
This study aimed to analyze associations between genetic variants and plasma concentrations along with clinical outcomes in dabigatran in patients with non-valvular atrial fibrillation (NVAF).
Methods
We conducted a prospective study and enrolled NVAF patients treated with dabigatran in the real world. A total of 86 patients treated with 110 mg DE twice daily were recruited for this study. Blood samples were obtained from each patient and used for genotyping and determination of plasma dabigatran concentration. All bleeding and thromboembolic complications were recorded during the 1.5 years of follow-up.
Results
Eighty-three patients provided samples at the trough plasma level of dabigatran, and 58 patients provided samples at the peak plasma level of dabigatran. There was a significant association between the CES1 SNP rs8192935 and trough plasma concentrations of dabigatran (P = 0.013). Our results showed that the CES1 SNP rs8192935 significantly influenced dabigatran trough concentrations in the Chinese population, and carriers of the G allele had increased trough plasma concentrations of dabigatran compared to noncarriers. The ABCB1 SNP c.2482-2236G > A (rs4148738) was associated with major bleeding events in the addictive model (P = 0.046, OR = 3.29) and dominant model (P = 0.040, OR = 8.17). Additionally, the ABCB1 SNP c.3435 C > T (rs1045642) was associated with the incidence of major bleeding events in the addictive model (P = 0.043, OR = 3.34) and dominant model (P = 0.046, OR = 7.77). However, no significant associations were found between all the SNPs and the incidence of minor bleeding events.
Conclusion
Our results indicated that the CES1 polymorphism rs8192935 was associated with trough plasma concentrations of dabigatran. Carriers of the G allele had increased trough plasma concentrations of dabigatran compared to noncarriers. The ABCB1 polymorphisms rs4148738 and rs1045642 were associated with an increased risk for major bleeding events for the first time in a Chinese population.

Novel oral anticoagulants versus vitamin K antagonists in patients with atrial fibrillation after transcatheter aortic valve replacement: A systematic review and meta-analysis. Catheter Cardiovasc Interv 2022; 99:2101-2110. [PMID: 35476221 DOI: 10.1002/ccd.30213] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/16/2021] [Revised: 03/02/2022] [Accepted: 04/03/2022] [Indexed: 11/09/2022]
Abstract
BACKGROUND The efficacy and safety of novel oral anticoagulants (NOACs) compared to the current guideline-recommended vitamin K antagonists (VKAs) in atrial fibrillation (AF) patients undergoing transcatheter aortic valve replacement (TAVR) has not been well established. We pooled evidence from all available studies to assess the risks and benefits of this drug class. METHODS We queried electronic databases (MEDLINE, Scopus, and Cochrane central) up until January 28th, 2022 for studies comparing NOACs to VKAs in AF patients undergoing TAVR. Results from studies were presented as risk ratios (RR) and pooled using a random-effects model. Subgroup analysis by study design and meta-regression analysis were performed to explore heterogeneity. RESULTS A total of 12 studies (3 RCTs and 9 observational) containing 12,203 patients (mean age 81.2 years; 50.5% men) were identified and included in the analysis. Pooled analysis revealed no significant difference between NOACs and VKAs in terms of stroke or systemic embolism (RR: 0.78; p = 0.18), major bleeding (RR: 0.84; p = 0.32), intracranial hemorrhage (RR 0.61; p = 0.06), all-cause mortality (RR: 0.69; p = 0.07), and myocardial infarction (RR: 1.60; p = 0.24) at a mean length of follow-up of 15.1 months. RCTs and observational studies did not significantly differ across outcomes on subgroup analysis. Meta-regression analysis found heterogeneity in all-cause mortality to be significantly explained by percentage of males (coefficient: 0.049, p = 0.007), mean age (coefficient: 0.221, p < 0.001), and CHA2DS2-VASc score (coefficient: -1.657, p < 0.001). CONCLUSIONS This meta-analysis suggests that outcomes with NOACs do not significantly differ compared to VKAs following TAVR in patients with AF.

Catheter Ablation in Adult Congenital Heart Disease on uninterrupted oral anticoagulation: Is it safe? - Data from a large single center study. Heart Rhythm 2021; 19:648-655. [PMID: 34958942 DOI: 10.1016/j.hrthm.2021.12.018] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/16/2021] [Revised: 12/16/2021] [Accepted: 12/17/2021] [Indexed: 11/24/2022]
Abstract
BACKGROUND Catheter ablation in adult congenital heart disease (ACHD) patients is a critical treatment strategy for complex arrhythmias including atrial fibrillation (AF) and atrial tachycardia (AT). In addition to vitamin K antagonists (VKA), direct oral anticoagulants (DOACs) are increasingly used in this patient population. OBJECTIVE The study assessed the safety of catheter ablation in ACHD patients on uninterrupted oral anticoagulation with VKA or DOAC examining thromboembolic, bleeding or vascular access complications. METHODS Retrospective analysis of 234 ACHD patients with simple (n=83), moderate (n=66) or complex (n=85) CHD (mean age 46 years) undergoing 368 ablation procedures on uninterrupted oral anticoagulation with VKA (45.4%) or DOAC (54.6 %) was undertaken. Arrhythmias were AF (n=97, right AT (n=181), left AT (n=65) or a combination of AF and AT (n=25). RESULTS No thromboembolic complications occurred. There were major complications in 4 patients (1.1%; VKA n=1, DOAC n=3) including retroperitoneal hematoma (n=2) and AV fistula requiring surgical treatment (n=2). Minor bleeding or vascular access complications occurred in 46 cases (12.5%) including hematomas >5cm (n=26), AV fistulas (not requiring surgical intervention) (n=13) or pseudoaneurysms (n=7; thrombin injection in 3/7). Overall, no significant difference was found between the DOAC (14.9%) and the VKA group (12. 0%; p=0.411). CONCLUSION Catheter ablation in ACHD patients on uninterrupted oral anticoagulation with VKA or DOAC is feasible and safe. No thromboembolic events occurred, and major bleeding or vascular access complications were rare. No significant difference regarding minor bleeding or vascular access complications between patients on DOAC or VKA were found.

Abstract
BACKGROUND The current emergency medicine literature on cardioversion for atrial fibrillation (AF) describes its performance on those who are hemodynamically unstable, present within 48 hours of the onset of the arrhythmia, or are on long-term anticoagulants. For patients who are not anticoagulated and present with atrial fibrillation for more than 48 hours, one option is to perform a transesophageal echocardiogram and then synchronized cardioversion in the absence of atrial clot. The objective of this study is to compare outcomes of patients presenting to the emergency department (ED) with atrial fibrillation (AF) of more than 48 hours who underwent a transesophageal echocardiogram (TEE) and subsequent cardioversion in the ED versus the cardiology ward. METHODS This was a retrospective comparison study of patients who presented to the ED with AF for more than 48 hours, underwent a transesophageal echocardiogram, and then were electrically cardioverted either in the emergency department or in the cardiology ward. Outcomes include: time to cardioversion, length of hospital stay, rate of successful cardioversion, and rate of complications. RESULTS Electrical cardioversion was performed in the ED on 94 patients (62%) and the cardiology ward on 57 (38%). Over 90% of cardioversions were successful in both groups. Time to cardioversion was significantly less in the ED group versus the cardiology group (1.04 ± 0.9 days versus 3.81 ± 1.9; P < .001). Similarly, the mean length of hospital stay was less for the ED group (1.6 ± 1.6 days versus 7.3 ± 3.5; P < .001). CONCLUSION Patients who present in atrial fibrillation for more than 48 hours and then have a TEE undergo electrical cardioversion faster in the ED compared with the cardiology ward. This clinical pathway also results in a shorter length of hospital stay without having more side effects.

Abstract
OBJECTIVE To explore anticoagulant usage patterns stratified by stroke and bleeding risk in elderly patients with non-valvular atrial fibrillation (NVAF). DESIGN Prospective, multicentre, observational cohort study. SETTING The real-world All Nippon AF In the Elderly (ANAFIE) registry. PARTICIPANTS Japanese patients aged ≥75 years with NVAF (n=32 726). OUTCOME MEASURES The distribution of stroke and bleeding risk scores, and the selection of anticoagulant regimen for patients at high stroke and bleeding risk. RESULTS Overall, 18 185 (55.6%) patients had a high risk of stroke (CHADS2 score ≥3). Of these, 12 561 (38.4% of the total ANAFIE population) had a low bleeding risk (HAS-BLED ≤2) and 5624 (17.2%) had a high bleeding risk (HAS-BLED ≥3). Significant differences were noted between the high versus low bleeding risk groups in sex, height, weight, systolic blood pressure and rates of abnormality of lipid metabolism, gastrointestinal disease, cerebrovascular disorders, chronic kidney disease, angina pectoris, respiratory disease, primary malignant tumour, dementia and fall history within the past year (all p<0.0001). Patients with high stroke and bleeding risks had a lower anticoagulant usage rate versus the low bleeding risk group, and 8.7% and 5.8%, respectively, were not receiving any anticoagulant (p<0.0001). Patients in the high bleeding risk group had a higher usage of warfarin versus the low bleeding risk group (p<0.0001); more patients (14.0%) in the high bleeding risk group receiving warfarin had time in the therapeutic range <40%, versus those in the low bleeding risk group (11.6%, p=0.0146). Direct-acting oral anticoagulants (DOACs) were used less in the high bleeding risk group, without notable differences in the DOAC dose distribution between the two groups. CONCLUSIONS In elderly NVAF patients at high stroke risk, significant demographic and clinical differences were observed according to bleeding risk. Administration of low-dose DOACs was frequent, but the dose distribution was unaffected by bleeding risk. TRIAL REGISTRATION NUMBER UMIN000024006 (http://www.umin.ac.jp/).

Abstract
We investigated the prevalence of retinal vascular occlusion and intraocular bleeding and compare their risks in patients undergoing anticoagulant therapy, either with non-vitamin K-antagonist oral anticoagulants (NOAC) or warfarin. We performed a cohort study (January 2015 to April 2018) in 281,970 patients with nonvalvular atrial fibrillation (AF) using health claims in the nationwide database of the Health Insurance Review and Assessment service of Korea. A Cox-proportional hazard regression was used to calculate the hazard ratio (HR) for retinal vascular occlusion or intraocular bleeding. The HR of retinal vascular occlusion was estimated to 1.59 (95% confidence interval [CI], 1.35–1.86) for NOAC users compared to that with warfarin users. Among the various types of NOACs, all NOACs showed higher risk of retinal vascular occlusion than did warfarin. For intraocular bleeding, the HR was estimated to be 0.86 (95% CI, 0.75–0.98) for NOAC users compared with that with warfarin users. The risk of retinal vascular occlusion was higher in NOAC users than in warfarin users, while the risk of intraocular bleeding was lower with NOAC therapy. NOACs were not found to be as effective as warfarin for retinal vascular occlusion, but safe in terms of intraocular bleeding.

Abstract
The role of oral anticoagulants (OAC) in atrial fibrillation (AF) is well established. However, none of the randomized controlled trials included patients with end-stage renal disease (ESRD) leaving a lack of evidence in this large, challenging and unique patient group. Patients on hemodialysis (HD) with AF have additional risk factors for stroke due to vascular comorbidities, HD treatment, age, and diabetes. Conversely, they are also at increased risk of major bleeding due to uremic platelet impairment. Anticoagulants increase bleeding risk in patients with ESRD and HD up to 10-fold compared with non chronic kidney disease (CKD) patients on warfarin. There are conflicting data and recommendations regarding use of OACs in ESRD which will be reviewed in this article. We conclude by proposing a modified strategy for OAC use in ESRD based on the latest evidence.

Abstract
The role of continued versus interrupted oral anticoagulation (OAC) in patients with atrial fibrillation (AF) who underwent transfemoral transcatheter aortic valve implantation (TF-TAVI) for severe aortic stenosis is uncertain. The aim of this retrospective investigation was to evaluate the impact (1) of continued versus interrupted OAC on early safety and (2) of postoperative anticoagulant management on the 1-year mortality in patients with AF who underwent TF-TAVI. Consecutive patients with AF and on OAC at admission (n = 598) were stratified according to interrupted (iVKA) versus continued vitamin K antagonist (cVKA) versus continued direct oral anticoagulants (DOAC) at the time of TF-TAVI. Valve Academic Research Consortium-2 early safety was the primary outcome measure. Patients with iVKA (n = 299), cVKA (n = 117), and DOAC (n = 182) had comparable baseline characteristics including age (p = 0.25), gender (p = 0.33), and STS-Score (p = 0.072). The proportion of patients having a CHA2DS2-VASc-Score ≥3 (p = 0.791) and HAS-BLED-Score ≥3 (p = 0.185) was not different between groups. The rate of early safety events (with lower values indicating superior safety) was lowest in DOAC (13.2%) and not increased in cVKA (19.7%) compared to iVKA (23.1%) (p = 0.029). Valve Academic Research Consortium-2 defined stroke (p = 0.527) and bleeding (p = 0.097) did not differ between groups. Renal failure occurred more often in iVKA compared to cVKA and DOAC (p = 0.02). All-cause 1-year mortality was 20.1% in iVKA, 13.7% in cVKA, and 8.8% in DOAC (p = 0.015). Multivariate analysis revealed DOAC to be associated with reduced all-cause 1-year mortality (HR 0.56 (95%-CI 0.32 to 0.99), p = 0.047) whereas cVKA was comparable to iVKA (HR 0.75 (95%-CI 0.43 to 1.31), p = 0.307). In conclusion, cVKA did not increase the rate for the composite end point of early safety at 30 days in this cohort of patients. Treatment with a DOAC was associated with a significantly reduced rate of early safety end points at 30 days and lower 1-year mortality.

New anticoagulants, reversal agents, and clinical considerations for perioperative practice. Best Pract Res Clin Anaesthesiol 2018; 32:165-178. [PMID: 30322457 DOI: 10.1016/j.bpa.2018.06.008] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2018] [Accepted: 06/18/2018] [Indexed: 11/21/2022]
Abstract
There are several new anticoagulants on the market that will impact perioperative care, including the use of these anticoagulant drugs in the setting of regional anesthesia. The ideal pharmacological agent would prevent pathological thrombosis and allow for a normal response to vascular injury to limit bleeding. At present, all antithrombotic agents have increased bleeding risk as their main side effect. We describe the different categories of drugs, e.g., antiplatelet, anticoagulant, and thrombolytic, with particular emphasis on the new drugs that have been introduced into the market. These agents can be evaluated by a number of methods including low-, medium-, or high-risk procedures and guidelines and best practice standards that have been published regarding the amount of time to wait after stopping the medication and before performing a procedure, e.g., the American Society of Regional Anesthesia and Pain Medicine recommendations. The present investigation will also describe new reversal agents for anticoagulants and the implications of all these drugs for regional anesthesia.
