J Clin Neurosci 2024; 124:144-149. [PMID: 38705027 DOI: 10.1016/j.jocn.2024.04.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Revised: 03/09/2024] [Accepted: 04/29/2024] [Indexed: 05/07/2024]
Abstract
BACKGROUND The effect of antithrombotic therapy on patients with atrial fibrillation who sustained previous intracerebral hemorrhage (ICH) remains uncertain. Data regarding antithrombotic therapy use in these patients are limited. This study aims to compare the clinical and overall outcomes of antithrombotic therapy and usual care in patients with atrial fibrillation who sustained ICH. METHODS We assembled consecutive patients with atrial fibrillation sustaining an ICH from our institution. Multivariable regression analysis and propensity-matched analysis were applied to assess associations of different antithrombotic therapies and outcomes. The primary outcome was mortality within the longest follow-up. Kaplan-Meier curves and log-rank tests of the time-to-event data were used to assess differences in survival. RESULTS In total, 296 consecutive patients with atrial fibrillation who survived an ICH were included in this study. Our analysis demonstrated that antithrombotic therapy was associated with reduced mortality up to a 4-year duration of follow-up (OR, 0.49, 95 % CI 0.30-0.81). Similar results were obtained from the propensity-matched analysis (OR, 0.58, 95 % CI 0.34-0.98). Subgroup analysis showed that compared with usual care, direct oral anticoagulant (DOAC) with or without antiplatelet was associated with a lower risk of long-term mortality (OR, 0.34, 95 % CI 0.17-0.69). In addition, our analysis observed a significant interaction between cardiac insufficiency and treatment effect (P = 0.04). CONCLUSIONS In patients with atrial fibrillation who have a history of ICH, administration of antithrombotic therapy, especially DOAC, was associated with lower mortality. Future randomized trials are warranted to test the positive net clinical benefit of DOAC therapy.

Abstract
The use of anticoagulants has become more frequent due to the progressive aging population and increased thromboembolic events. Consequently, the proportion of anticoagulant-associated intracerebral hemorrhage (AAICH) in stroke patients is gradually increasing. Compared with intracerebral hemorrhage (ICH) patients without coagulopathy, patients with AAICH may have larger hematomas, worse prognoses, and higher mortality. Given the need for anticoagulant reversal and resumption, the management of AAICH differs from that of conventional medical or surgical treatments for ICH, and it is more specific. Understanding the pharmacology of anticoagulants and identifying agents that can reverse their effects in the early stages are crucial for treating life-threatening AAICH. When patients transition beyond the acute phase and their vital signs stabilize, it is important to consider resuming anticoagulants at the right time to prevent the occurrence of further thromboembolism. However, the timing and strategy for reversing and resuming anticoagulants are still in a dilemma. Herein, we summarize the important clinical studies, reviews, and related guidelines published in the past few years that focus on the reversal and resumption of anticoagulants in AAICH patients to help implement decisive diagnosis and treatment strategies in the clinical setting.

Abstract
EDOSURE is a trial program of the direct oral anticoagulant drug edoxaban, comprising ten randomized clinical trials of which eight are currently published. They evaluate the use of edoxaban in the treatment of nonvalvular atrial fibrillation and acute venous thromboembolism, including in special circumstances such as patients undergoing cardiac procedures, cancer-associated venous thromboembolism, and elderly patients whose bleeding risk precludes conventional anticoagulation strategies. As a result of the collective evidence generated by EDOSURE, edoxaban is now recommended as a treatment option by numerous international guidelines. This review summarizes the context, rationale, and key findings of the studies.

Abstract
Anti-amyloid immunotherapies have recently emerged as treatments for Alzheimer's disease. While these therapies have demonstrated efficacy in clearing amyloid-β and slowing cognitive decline, they have also been associated with amyloid-related imaging abnormalities (ARIA) which include both edema (ARIA-E) and hemorrhage (ARIA-H). Given that ARIA have been associated with significant morbidity in cases of antithrombotic or thrombolytic therapy, an understanding of mechanisms of and risk factors for ARIA is of critical importance for stroke care. We discuss the latest data regarding mechanisms of ARIA, including the role of underlying cerebral amyloid angiopathy, and implications for ischemic stroke prevention and management.

Abstract
BACKGROUND The purpose of this meta-analysis was to compare efficacy and safety of direct oral anticoagulants (DOACs) to warfarin for secondary stroke prevention among adult patients with atrial fibrillation and prior stroke. METHODS Major repositories were screened for randomized controlled trials (RCTs), RCT subgroups, and observational studies (OBSs, divided in claims and non-claims). Occurrences of ischemic stroke or transient ischemic attack, systemic embolism, all-cause mortality, intracranial hemorrhage (ICH), and major bleeding were outcomes of interest. Hazard ratios (HRs) and their confidence intervals (95%CIs) were pooled using random-effects models for each study design. Claims studies were analyzed separately from non-claims, while RCT subgroups were grouped with OBSs (non-claims) as the randomization was broken. RESULTS Of 8647 articles, 20 were included (one RCT, six RCT subgroups, nine claims, and four non-claims). Comparing DOACs to warfarin, pooled HRs (95%CI) were consistently in favor of DOACs although some did not reach statistical significance: for ischemic stroke, 0.84 (0.66-1.07) in claims; 0.90 (0.77-1.06) in non-claims and RCT subgroups; for systemic embolism, 0.77 (0.62-0.96) in claims; 0.86 (0.77-0.96) in non-claims and RCT subgroups; for all-cause mortality, 0.57 (0.33-0.99) in claims; 0.87 (0.79-0.96) in non-claims and RCT subgroups; for ICH, 0.72 (0.39-1.33) in claims; 0.51 (0.38-0.67) in non-claims and RCT subgroups; and for major bleeding, 0.86 (0.71-1.03) in claims; 0.90 (0.76-1.08) for non-claims and RCT subgroups. CONCLUSION DOACs were associated with better efficacy and safety profiles than warfarin in atrial fibrillation patients with prior stroke, more specifically a lower risk of systemic embolism, all-cause mortality, and ICH.

Abstract
INTRODUCTION Current evidence regarding the clinical outcomes of non-vitamin K oral anticoagulants (NOACs) versus warfarin in patients with atrial fibrillation (AF) and previous stroke is inconclusive, especially in patients with previous intracranial haemorrhage (ICrH). We aim to undertake a systematic review and meta-analysis assessing the effectiveness and safety of NOACs versus warfarin in AF patients with a history of stroke. METHODS We searched studies published up to December 10, 2022, on PubMed, Medline, Embase, and Cochrane Central Register of Controlled Trials. Studies on adults with AF and previous ischaemic stroke (IS) or IrCH receiving either NOACs or warfarin and capturing outcome events (thromboembolic events, ICrH, and all-cause mortality) were eligible for inclusion. RESULTS Six randomized controlled trials (RCTs) (including 19,489 patients with previous IS) and fifteen observational studies (including 132,575 patients with previous IS and 13,068 patients with previous ICrH) were included. RCT data showed that compared with warfarin, NOACs were associated with a significant reduction in thromboembolic events (odds ratio [OR]: 0.85, 95% confidence interval [CI]: 0.75-0.96), ICrH (OR: 0.57, 95% CI: 0.36-0.90), and all-cause mortality (OR: 0.88, 95% CI: 0.80-0.98). In analysing observational studies, similar results were retrieved. Moreover, patients with previous ICrH had a lower OR on thromboembolic events than those with IS (OR: 0.66, 95% CI: 0.46-0.95 vs. OR: 0.80, 95% CI: 0.70-0.93) in the comparison between NOACs and warfarin. CONCLUSIONS Observational data showed that in AF patients with previous stroke, NOACs showed better clinical performance compared to warfarin and the benefits of NOACs were more pronounced in patients with previous IrCH versus those with IS. RCT data also showed NOACs are superior to warfarin. However, current RCTs only included AF patients who survived an IS, and further large RCTs focused on patients with previous ICrH are warranted.

Abstract
BACKGROUND The benefit of resuming anticoagulation in atrial fibrillation (AF) patients with prior intracranial haemorrhage (ICH) and which anticoagulant to choose are controversial. SUMMARY OF REVIEW PubMed, Embase, Web of Science and the Cochrane Library were searched from their inception until 13 February 2022. Thirteen eligible articles (17 600 participants) were collected, including 11 real-world studies (n=17 296) and 2 randomised controlled trials (RCTs) (n=304). Compared with no anticoagulants, oral anticoagulation (OAC) was not associated with an increased risk of ICH recurrence (HR 0.85 (95% CI 0.57 to 1.25), p=0.41), but with a significantly increased risk of major bleeding (HR 1.66 (95% CI 1.20 to 2.30), p<0.01). Meanwhile, OAC was associated with a reduced risk of ischaemic stroke/systemic thromboembolism (IS/SE) (HR 0.54 (95% CI 0.42 to 0.70), p<0.01) and all-cause death (HR 0.38 (95% CI 0.28 to 0.52), p<0.01) compared with no anticoagulants. Furthermore, compared with warfarin, non-vitamin K antagonist oral anticoagulants (NOACs) were associated with a significant reduction of ICH recurrence (HR 0.64 (95% CI 0.49 to 0.85), p<0.01), while the risk of IS/SE and all-cause mortality were comparable between warfarin and NOACs. CONCLUSIONS For patients with AF with prior ICH, OAC is associated with a significant reduction in IS/SE and all-cause mortality without increasing ICH recurrence, but may increase major bleeding risk. Compared with warfarin, NOACs had a better safety profile and comparable efficacy. Further larger RCTs are warranted to validate these findings.

Abstract
INTRODUCTION Oral anticoagulants (OACs) are the cornerstone of stroke prevention in atrial fibrillation (AF), but prescribing decisions in older people are complicated. Clinicians must assess the net clinical benefit of OAC in the context of multiple chronic conditions, polypharmacy, frailty and life expectancy. The under-representation of high-risk, older adult sub-populations in clinical trials presents the challenge of choosing the right OAC, where a 'one-size-fits-all' approach cannot be taken. AREAS COVERED This review discusses OAC approaches for stroke prevention in older people with AF and presents a prescribing aid to support clinicians' decision-making. High-risk older adults with multiple chronic conditions, specifically chronic kidney disease, dementia/cognitive impairment, previous stroke/transient ischemic attack or intracranial hemorrhage, polypharmacy, frailty, low body weight, high falls risk, and those aged ≥75 years are considered. EXPERT OPINION Non-vitamin K antagonist OACs are the preferred first-line OAC in older adults with AF, including high-risk subpopulations, after individual assessment of stroke and bleeding risk, except those with mechanical heart valves and moderate-to-severe mitral stenosis. Head-to-head comparisons of NOACs are not available, therefore the choice of drug (and dose) should be based on an individual's risk (stroke and bleeding) and incorporate their treatment preferences. Treatment decisions must be person-centered and principles of shared decision-making applied.

Abstract
Background The atrial fibrillation better care (ABC) pathway is a simple, comprehensive framework that facilitates provision of integrated care for atrial fibrillation (AF) patients. Objective We evaluated management of AF patients in a secondary prevention cohort using the ABC pathway and examined the impact of ABC adherence on clinical outcomes. Methods The Chinese Patients with Atrial Fibrillation registry is a prospective registry conducted in 44 sites across China between October 2014 and December 2018. The primary outcome was the composite of all-cause mortality/any thromboembolism (TE), all-cause death, any TE and major bleeding at 1 year. Results Of the 6420 patients, 1588 (24.7%) had a prior stroke or transient ischemic attack and were identified as the secondary prevention cohort. After excluding 793 patients due to insufficient data, 358 (22.5%) were ABC compliant and 437 (27.5%) ABC noncompliant. ABC adherence was associated with a significantly lower risk of the composite outcome of all-cause death/TE, odds ratio (OR) 0.28 (95% confidence interval [CI]: 0.11-0.71) and all-cause death, OR 0.29 (95% CI: 0.09-0.90). Significant differences were not observed for TE, OR 0.27 (95% CI: 0.06-1.27) and major bleeding, OR 2.09 (95% CI: 0.55-7.97). Age and prior major bleeding were significant predictors of ABC noncompliance. Health-related quality of life (QOL) was higher in the ABC compliant group versus the noncompliant group (EQ score 0.83 ± 0.17 vs. 0.78 ± 0.20; p = .004). Conclusion ABC pathway adherence in secondary prevention AF patients was associated with a significantly lower risk of the composite outcome of all-cause death/TE and all-cause death, as well as better health-related QOL.

Abstract
BACKGROUND The relative effectiveness of anticoagulation agents in patients with atrial fibrillation (AF) who survive an intracranial hemorrhage (ICH) is unknown. This study was performed to examine the comparative effectiveness of different oral anticoagulation (OAC) on clinical outcomes in this group of patients. METHODS We performed a Bayesian network meta-analysis of randomized controlled trials (RCTs) and observational studies comparing different OAC (direct oral anticoagulant [DOAC] and warfarin) for the treatment of patients with AF who sustained ICH. Outcomes included repeat ICH, thromboembolic events, and all-cause mortality. The values derived from the surface under the cumulative ranking curve were obtained to rank the treatment hierarchy. RESULTS We identified 12 studies (two RCTs and ten observational studies) involving 23,265 patients; 346 patients were treated with any OAC agents; 5,006 received DOAC; 5,271 received warfarin; 12,007 received antiplatelet or no therapy, and 635 did not received relevant therapy. Both DOAC and warfarin (RR, 0.58; 95% CI, 0.45-0.74; RR, 0.83; 95% CI, 0.69-0.98) were superior to antiplatelet or no therapy in preventing thromboembolic events. Moreover, DOAC also showed superiority in preventing thromboembolic events (RR, 0.70; 95% CI, 0.58-0.83), repeat ICH (RR, 0.52; 95% CI, 0.40-0.67), and all-cause mortality (RR, 0.51; 95% CI, 0.46-0.56) than warfarin. CONCLUSIONS Our study suggests DOACs may be a reasonable alternative to anti-platelet therapy and warfarin for patients with AF who experienced ICH. However, given the available evidence is primarily observational, further validation by ongoing trials directly comparing these two classes of drugs are needed.

Abstract
Atrial fibrillation (AF) and venous thromboembolism (VTE) are highly prevalent conditions with a significant healthcare burden, and represent the main indications for anticoagulation. Direct oral anticoagulants (DOACs) are the first choice treatment of AF/VTE, and have become the most prescribed class of anticoagulants globally, overtaking vitamin K antagonists (VKAs). Compared to VKAs, DOACs have a similar or better efficacy/safety profile, with reduced risk of intracerebral hemorrhage (ICH), while the risk of major bleeding and other bleeding harms may vary depending on the type of DOAC. We have critically reviewed available evidence from randomized controlled trials and observational studies regarding the risk of bleeding complications of DOACs compared to VKAs in patients with AF and VTE. Special patient populations (e.g., elderly, extreme body weights, chronic kidney disease) have specifically been addressed. Management of bleeding complications and possible resumption of anticoagulation, in particular after ICH and gastrointestinal bleeding, are also discussed. Finally, some suggestions are provided to choose the optimal DOAC to minimize adverse events according to individual patient characteristics and bleeding risk.

Abstract
Pharmacovigilance is used to detect, assess, understand, and prevent the adverse effects of medications. The need for safety monitoring has evolved around unfortunate incidents in history, with deaths caused by anesthesia and congenital malformations from thalidomide use. Reports from adverse drug reactions (ADRs) are stored in a global database and can be used to evaluate the associations between various medications and associated ADRs. Clinicians play an important role in the recognition and reporting of ADRs to national pharmacovigilance centers (NPCs). The purpose of NPCs is to make the clinicians understand their functions, including the monitoring, investigation, and assessment of ADR reports, along with periodical benefit-risk assessments of medications via multiple sources. A case study on NPCs and the types of safety issues evaluated by them are provided to illustrate their role in medicine safety surveillance. ADR monitoring was also combined with vaccine safety surveillance approaches. Overall, this study will provide insights to clinicians on the importance of pharmacovigilance in maintaining patient safety with the proper use of medications.

Abstract
Warfarin is the standard of care, and direct oral anticoagulants (DOACs) are a group of newer drugs to prevent stroke in patients with valvular heart disease. The aim of this meta-analysis is to compare the efficacy and safety of DOACs and warfarin in the prevention of stroke in patients with valvular heart disease (VHD). The current meta-analysis was conducted using the standards developed by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendation. The databases from the Cochrane library, PubMed, and Excerpta Medica database (EMBASE) were used to search for relevant articles without placing restrictions on the year of publication. Outcomes assessed in the current meta-analysis included a number of patients with stroke or systemic embolism, patients having myocardial infarction during the study period, patients with major bleeding events, and patients who died due to any reason. Overall, five studies were included in the current meta-analysis. Direct oral anticoagulants were associated with a lower risk of stroke or systemic embolism in patients with VHD (relative risk (RR): 0.75, 95% confidence interval (C)I: 0.60 to 0.94). The risk of major bleeding events is 31% lower in patients receiving DOAC compared to patients receiving warfarin (RR: 0.69, 95% CI: 0.58 to 0.83). No significant difference was found between the two groups in terms of all-cause mortality and myocardial infarction. The current meta-analysis shows that DOACs were associated with a lower risk of stroke or systemic embolism as compared to warfarin in patients with VHD. Besides this, the risk of major bleeding events was also lower in patients receiving DOACs compared to patients receiving warfarin. No significant differences were reported in terms of myocardial infarction and all-cause mortality between the two groups.

Abstract
Whether restarting anticoagulation (RA) treatment after intracranial hemorrhage (ICH) is still controversial. We performed a systematic review and meta-analysis to summarize the relationship between anticoagulation after ICH with the recurrence of hemorrhagic events, ischemic events, and long-term mortality. Medline, Embase, and the Cochrane Central Register of Controlled Trials, from inception to November 2020. We searched the published medical literature to ensure cohort studies involving ICH associated with anticoagulation in adults. Primary outcomes were long-term mortality, hemorrhagic events, and ischemic events (myocardial infarction, pulmonary embolism, ischemic stroke, or systemic embolization). We concluded seven retrospective cohorts, including 1876 intracranial hemorrhage patients with indications of anticoagulation. The ratio of the anticoagulant restart was 35.3% (664n). RA was associated with a significantly lower incidence of recurrent ischemic events (pooled odds ratio [OR] 0.29, 95% confidence interval [CI] 0.19% to 0.45%, p = 0.97) and death events (pooled OR 0.56, 95% CI 0.40%-0.79%, p = 0.27). There is no evidence that early recovery of anticoagulation (within 2 weeks or 1 month) is associated with the occurrence of hemorrhagic events (within 2 weeks: pooled OR 0.80, 95% CI 0.3-2.12, p = 0.52 vs. within 1 month: pooled OR 1.14, 95% CI 0.77-1.68, p = 0.82). Based on these, recovery of anticoagulation after ICH is beneficial for long-term mortality and recurrence of ischemic events. The meta-analysis showed a resumption of oral anticoagulation within 2 weeks or 1 month in patients who had a cerebral hemorrhage was beneficial and did not increase the risk of hemorrhagic events and reduced the occurrence of ischemic and fatal endpoint events.

Abstract
Background Intracranial hemorrhage (ICH) is excluded in most anticoagulation randomized clinical trials (RCTs), so oral anticoagulant (OAC) therapy is still the conventional treatment for patients with atrial fibrillation (AF) after ICH. Therefore, we conducted a meta-analysis to determine the effectiveness and safety outcomes of OAC for these patients. Methods We systematically searched the PubMed and Embase databases up to March 2022 for RCTs and observational studies exploring the effect of OAC in patients with AF after ICH. The effectiveness outcomes included stroke or systemic embolism, ischemic stroke, and all-cause death, whereas the safety outcomes were major bleeding and recurrent ICH. Hazard ratios (HRs) and 95% confidence intervals (CIs) from each study were pooled using a random-effects model. Results A total of 14 studies were included. The OAC therapy that was performed reduced the risks of stroke or systemic embolism (HR = 0.65, 95% CI 0.53-0.81), ischemic stroke (HR = 0.70, 95% CI 0.60-0.82), and all-cause death (HR = 0.43, 95% CI 0.27-0.70) but had a higher risk of major bleeding (HR = 1.50, 95% CI 0.94-2.40) and showed no difference in recurrent ICH (HR = 0.91, 95% CI 0.53-1.55) compared to the no OAC therapy. With the use of non-vitamin K antagonist oral anticoagulant (NOAC) therapy, a lower risk of stroke or systemic embolism (HR = 0.83, 95% CI 0.70-0.98), all-cause death (HR = 0.67, 95% CI 0.53-0.84), and recurrent ICH (HR = 0.68, 95% CI 0.54-0.86) was observed against the use of vitamin K antagonists (VKA) therapy. Conclusion The OAC therapy (especially VKA) revealed superior effectiveness in patients with AF after ICH, and the superiority of NOAC was also found, but some related evidence was limited.

Abstract
BACKGROUND:
For patients with atrial fibrillation who survive an intracranial hemorrhage (ICrH), the decision to offer oral anticoagulation (OAC) is challenging and necessitates balancing risk of thromboembolic events with risk of recurrent ICrH.
METHODS:
This systematic review assesses the effectiveness and safety of OAC and/or antiplatelets in patients with atrial fibrillation with nontraumatic ICrH. Bibliographic databases CENTRAL, MEDLINE, EMBASE, and CINAHL were searched. Articles on adults with atrial fibrillation with spontaneous ICrH (intracerebral, subdural, and subarachnoid), receiving antithrombotic therapy for stroke prevention were eligible for inclusion.
RESULTS:
Twenty articles (50 470 participants) included 2 randomized controlled trials (n=304)‚ 8 observational studies, 8 cohort studies, and 2 studies that meta-analyzed individual-level data from observational studies. OAC therapy was associated with a significant reduction in thromboembolic events (summary relative risk [sRR], 0.51 [95% CI, 0.30–0.86], heterogeneity I
2
=2%;
P
=0.39, n=5 studies) and all-cause mortality (sRR, 0.52 [95% CI, 0.38–0.71], heterogeneity I
2
=0;
P
=0.44, n=3 studies). OAC therapy was not associated with an increased risk of recurrent ICrH (sRR, 1.44 [95% CI, 0.38–5.46], heterogeneity I
2
=70%,
P
=0.02, n=5 studies). Nonvitamin K antagonist OACs were more effective at reducing the risk of thromboembolic events (sRR, 0.65 [95% CI, 0.44–0.97], heterogeneity I
2
=72%,
P
=0.03, n=3 studies) and were associated with a lower risk of recurrent ICrH (sRR, 0.52 [95% CI, 0.40–0.67], heterogeneity I
2
=0%,
P
=0.43, n=3 studies) than warfarin.
CONCLUSIONS:
In nontraumatic ICrH survivors with atrial fibrillation, OAC therapy is associated with a reduced risk of thromboembolic events and all-cause mortality without significantly increasing risk of recurrent ICrH. This finding is primarily based on observational data, and further larger randomized controlled trials are needed to corroborate or refute these findings.

Abstract
This retrospective cohort study was performed using the Korean national health insurance claims data. Compared with non-usage of antithrombotics, a consistent usage of anticoagulants or antiplatelets was associated with lesser severe thrombotic events and severe hemorrhage events in patients with AF who survived an intracranial hemorrhage. Furthermore, compared with warfarin, novel direct anticoagulants were associated with a lower risk of thrombotic events.
Background Resuming anticoagulation after an intracranial hemorrhage (ICH) poses a clinical conundrum. The absence of relevant guidelines has led to wide variations in the decision on resuming anticoagulation therapies after ICH. This study aimed to evaluate the risks of an anticoagulation therapy on severe thrombotic events (STE) and severe hemorrhage events (SHE) in Korea and compare the effects of novel direct oral anticoagulants (NOACs) and warfarin in patients with AF. Methods This study was performed using the Korean national health insurance claims data obtained between 2002 and 2017 from individuals who had recently survived an ICH with comorbid AF. The endpoints of this study were STE and SHE. Anticoagulants, antiplatelet agents, and non-antithrombotic users were analyzed for survival with propensity score matching. Results Among the 4,964 participants analyzed, 878 (17.7%) and 2,070 (41.7%) used anticoagulant and antiplatelet agents, respectively. Anticoagulant (hazard ratio [HR] for STE: 0.385, P < 0.0001; HR for SHE: 0.578, P < 0.0001) or antiplatelet users (HR for STE: 0.545, P < 0.0001; HR for SHE: 0.637, P < 0.0001) had a lower risk of STE and SHE than non-antithrombotic users. Anticoagulation 6–8 weeks post-ICH showed a tendency of the lowest risk of all-cause mortality (HR: 0.614, P = 0.0552). However, there was no difference in the risk between the anticoagulant and antiplatelet users. Further, NOACs were associated with a lower risk of STEs than warfarin (HR, 0.263; P < 0.0001). Conclusions Our results showed that in patients with AF, resuming anticoagulants and antiplatelets after ICH improved the STEs and SHEs. Further, NOAC had additional benefits as compared to warfarin.

Abstract
Introduction There are a paucity of real-world data examining effectiveness and safety of non-vitamin K antagonist oral anticoagulants (NOACs) and warfarin in nonvalvular atrial fibrillation (NVAF) patients with prior bleeding. Methods This retrospective analysis included data from 5 insurance claims databases and included NVAF patients prescribed OACs with prior bleeding. One-to-one propensity score matching was conducted between NOACs and warfarin and between NOACs in each database. Cox proportional hazards models were used to evaluate the risk of stroke/systemic embolism (SE) and MB. Results A total of 244,563 patients (mean age 77; 50% female) with prior bleeding included 55,094 (22.5%) treated with apixaban, 12,500 (5.1%) with dabigatran, 38,246 (15.6%) with rivaroxaban, and 138,723 (56.7%) with warfarin. Apixaban (hazard ratio [HR]: 0.76 [95% CI: 0.70, 0.83]) and rivaroxaban (HR: 0.79 [95% CI: 0.71, 0.87]) had a lower risk of stroke/SE vs. warfarin. Apixaban (HR: 0.67 [95% CI: 0.64, 0.70]) and dabigatran (HR: 0.88 [95% CI: 0.81, 0.96]) had a lower risk of MB vs. warfarin. Apixaban patients had a lower risk of stroke/SE vs. dabigatran (HR: 0.70 [95% CI: 0.57, 0.86]) and rivaroxaban (HR: 0.85 [95% CI: 0.76, 0.96]) and a lower risk of MB than dabigatran (HR: 0.73 [95% CI: 0.67, 0.81]) and rivaroxaban (HR: 0.64 [95% CI: 0.61, 0.68]). Conclusions In this real-world analysis of a large sample of NVAF patients with prior bleeding, NOACs were associated with similar or lower risk of stroke/SE and MB vs. warfarin and variable risk of stroke/SE and MB against each other. Supplementary information The online version contains supplementary material available at 10.1007/s11239-022-02660-2. Data on NOAC effectiveness and safety in NVAF patients with prior bleed history are lacking. This study included data on OAC-treated NVAF patients with a history of bleeding. NOACs were associated with similar or lower risk of stroke/SE and MB vs. warfarin. NOACs were associated with variable risk of stroke/SE and MB against each other. This study further demonstrated the effectiveness and safety profile when comparing NOACs to warfarin. The findings could aid to inform the discussion on the benefits and risks in the decision making process for NVAF patients who had a prior bleed.

Abstract
INTRODUCTION Treatment persistence for anticoagulant therapy is important in preventing thromboembolism in nonvalvular atrial fibrillation (NVAF) patients. Understanding drug utilization pattern and treatment changes in oral anticoagulant (OAC) users may facilite better NVAF management. Thus, our study aimed to examine OAC treatment patterns preceding events leading to switch or discontinuation and medication adherence in Korean NVAF patients. METHODS We conducted a drug utilization study on all Korean patients with atrial fibrillation (AF) newly prescribed OACs between July 2015 and November 2016 using the national claims data. We assessed treatment changes such as switching and discontinuation from index OAC and relevant events preceding the change and examined patient characteristics as predictors of changes that occurred among OAC users. Medication adherence was compared among OAC users by calculating the medication possession ratio (MPR). RESULTS A total of 48,389 NVAF patients were identified who initiated OACs within the study period. Most initiated nonvitamin K antagonist oral anticoagulants (NOACs) (22% apixaban, 24% dabigatran, 37% rivaroxaban), and 18% initiated warfarin. The frequency of switch to another OAC was 8.8% for apixaban, 16.1% for dabigatran, 6.6% for rivaroxaban, and 19.1% for warfarin. The frequency of discontinuation was lower for apixaban (22.9%), dabigatran (26.3%), and rivaroxaban (25.7%) than warfarin (31.6%). Compared to warfarin, NOAC users were less likely to switch treatment. Thromboembolic event was the most common clinical event preceding switch from warfarin to NOAC and from NOAC to warfarin. Discontinuation of OAC was often preceded by a bleeding event. Patients who initiated apixaban showed significantly higher mean MPR compared to those on dabigatran and warfarin. CONCLUSION In real-world practice in Korea, we have observed treatment change to be common in OAC users. Our results indicate better medication adherence with NOACs than with warfarin.

Abstract
BACKGROUND Patients with atrial fibrillation (AF) require oral anticoagulation to prevent ischemic stroke. However, oral anticoagulation may cause bleeding, and patients with AF and a history of bleeding were excluded from pivotal trials comparing non-vitamin K antagonist oral anticoagulants (NOACs) and warfarin. We therefore aimed to assess the efficacy and safety of NOACs compared with warfarin in patients with AF and a history of bleeding. METHODS We conducted a systematic review of retrospective studies and clinical trials using the PubMed, EMBASE, SCOPUS, Cochrane Library, and Web of Science databases to May 2021. RESULTS Overall, 56,697 patients from six studies were included. NOACs significantly reduced the risk of ischemic stroke (hazard ratio [HR] 0.73, 95% confidence interval [CI] 0.59-0.91; p = 0.005), fatal ischemic stroke (HR 0.49, 95% CI 0.39-0.61; p < 0.001), all-cause mortality (HR 0.70, 95% CI 0.50-0.98; p = 0.04), major bleeding events (HR 0.75, 95% CI 0.67-0.84; p < 0.001), intracranial hemorrhage (ICH; HR 0.63, 95% CI 0.48-0.82; p < 0.001), fatal ICH (HR 0.33, 95% CI 0.20-0.56, p < 0.001), and gastrointestinal bleeding (HR 0.83, 95% CI 0.72-0.96; p = 0.01). CONCLUSIONS NOACs showed better efficacy and safety profile compared with warfarin in patients with AF and a history of bleeding. Randomized controlled trials are warranted to validate these findings.

Abstract
Intracerebral hemorrhage (ICH) remains a common and debilitating form of stroke. This neurological emergency must be diagnosed and treated rapidly yet effectively. In this article, we review the medical, surgical, repair, and regenerative treatment options for managing ICH. Topics of focus include the management of blood pressure, intracranial pressure, coagulopathy, and intraventricular hemorrhage, as well as the role of surgery, regeneration, rehabilitation, and secondary prevention. Results of various phase II and III trials are incorporated. In summary, ICH patients should undergo rapid evaluation with neuroimaging, and early interventions should include systolic blood pressure control in the range of 140 mmHg, correction of coagulopathy if indicated, and assessment for surgical intervention. ICH patients should be managed in dedicated neurosurgical intensive care or stroke units where continuous monitoring of neurological status and evaluation for neurological deterioration is rapidly possible. Extravasation of hematoma may be helpful in patients with intraventricular extension of ICH. The goal of care is to reduce mortality and enable multimodal rehabilitative therapy.

J Thromb Thrombolysis 2021; 53:683-689.

Abstract
Mechanical fall is common among elders and has been associated with a lack of anticoagulant therapy among patients with atrial fibrillation (AF). However, anticoagulant therapy is recommended despite frequent fall due to an increased risk of a thromboembolic event. Using data from a large health system, we investigated the predictors of anticoagulation prescription on discharge in AF elderly patients after an in-hospital fall. In this retrospective analysis, we examined patients aged 60 years and older discharged from 2013 to 2018 with a diagnosis of AF and a secondary diagnosis of in-hospital fall. The primary outcome was the prescription of anticoagulation at discharge. We obtained patients' demographical (race, sex, and health insurance status) and clinical (management by a resident team, receipt of a head CT or a cardiology consultation, ambulation status and discharge location) data. We further categorized the type of anticoagulation prescribed as warfarin or novel oral anticoagulants (NOACs). We ran chi-square and Fischer's exact tests on all data and multivariable logistic regressions on those of patients with pre-existing AF to identify the predictors of anticoagulation prescription on discharge. In total, 67% of 235 patients were discharged on anticoagulation. Of patients admitted on anticoagulation, 91% were prescribed anticoagulation on discharge (p < 0.001), while only 40% of patients with new-onset AF were discharged on anticoagulation (p < 0.001). Patients over the age of 90, compared to those aged 60-89, with existing AF had lower odds (OR = 0.34 [95% CI 0.12-0.98]) of being prescribed anticoagulation on discharge. Among patients with preexisting AF, being admitted on anticoagulation increased the odds (OR = 39.8 [15.2-104.0]) of anticoagulation prescription on discharge. Asian patients with prior AF were less likely (OR = 0.12 [0.026-0.060]) to receive anticoagulation on discharge. Of patients with new AF, 81% were prescribed a NOAC as opposed to warfarin (p < 0.05). These results suggest that provider's decisions on anticoagulation initiation seem to be guided more by their concerns over bleeding complications than by the patient's risk for stroke. However, anchoring bias strongly influences anticoagulation prescription. It may benefit AF patients already on anticoagulation, but it may prevent anticoagulation prescription in patients with new AF and Asian patients.

Abstract
Purpose Patients with stroke are at high risk of recurrence of vascular events. Non‐vitamin K oral anticoagulant (NOAC) and vitamin K antagonists (VKA) are used as secondary prophylaxis. The aim of this study was to evaluate the utilization of NOAC and VKA, and their impact on re‐stroke or death in Austria. Methods We analyzed retrospective data between 2012 and 2017 from medical services covered by the health insurance funds, which provides health care for all residents in Austria. Patients without anticoagulant medication 3 months preceding the index event were eligible. Results 76 354 patients were discharged with a hospital diagnosis of stroke. From these, 16 436 patients with a median age of 78 years received VKA or NOAC. After adjustment, the recurrence of stroke was less frequent in patients with NOAC compared to those with VKA (HR 0.87; 95%CI 0.77–0.97). However, there was no difference in mortality rate after adjustment for age, sex, and co‐morbidities for patients with NOAC (HR 1.0; 95%CI 0.92–1.08). Diabetes (HR 1.25, 95%CI 1.08–1.45; HR 1.25, 95% CI 1.13–1.38) and cardiovascular disease (HR 1.43, 95%CI 1.24–1.65; HR 1.27, 95%CI 1.16–1.39) were significantly associated with re‐stroke or death. Younger age (p = 0.0028; HR 0.99, 95%CI 0.99–0.99) was significantly associated with re‐stroke, and advanced age (p < 0.0001; HR 1.09, 95%CI 1.08–1.09) with death. Conclusion NOAC prescription is related with a reduced risk of re‐stroke but increased mortality compared to patients with VKA. The event risk is associated with diabetes, cardiovascular disease and age.

Abstract
ABSTRACT The aim of the present study is to identify a potential association of urinary tract infections (UTI) in a large population of patients receiving oral anticoagulation therapy treated in general practices in Germany. This study contains patients diagnosed with atrial fibrillation who received at least one prescription of either non-vitamin K antagonist oral anticoagulation (NOAC) or vitamin K antagonists (VKA) within January 2015 and December 2018. The incidence of UTI was examined cumulatively on the basis of Kaplan-Meier methods and was complemented by incidence rates measured in cases per 1000 patient years. Sex-stratified Cox regressions were conducted to examine possible associations in specific sex groups. The study comprised 26,934 patients receiving NOAC therapy and 8121 patients treated with VKA agents. Within a period of 5 years, slightly more NOAC than VKA users were diagnosed with UTI (20.3% vs. 19.3%), whereas the incidence rate was slightly higher in patients receiving NOAC therapy than in those under VKA treatment (50.8 cases vs. 50.5 cases in 1000 patient years). There was no significant association between direct oral anticoagulants versus vitamin K antagonists and infections of the urinary tract. Our study did not identify any significant association between therapy with direct oral anticoagulants versus vitamin K anticoagulants and UTI in patients diagnosed with atrial fibrillation in general practices in Germany. Because current findings regarding the risk of UTI in patients receiving oral anticoagulation therapy remain limited and contradictory, further investigations including a broad patient population are necessary to determine patients at risk for UTI and reconcile conflicting evidence.

Abstract
Several observational studies have compared the effectiveness and safety outcomes between nonvitamin K antagonist oral anticoagulants (NOACs) and vitamin K antagonists (VKAs) in atrial fibrillation (AF) patients with a history of either stroke/transient ischemic attack (TIA) or intracranial hemorrhage. Therefore, our current meta-analysis aimed to address this issue. The Cochrane Library, PubMed, and Embase databases were systematically searched until December 2020 for all relevant observational studies. We applied a random-effects model to pool adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for this meta-analysis. A total of 10 studies were included. Among patients with a history of stroke/TIA, the use of NOACs versus VKAs was associated with decreased risks of stroke (HR, 0.82, 95% CI 0.69-0.97), systemic embolism (HR, 0.73, 95% CI 0.61-0.87), all-cause death (HR, 0.87, 95% CI 0.81-0.94), major bleeding (HR, 0.77, 95% CI 0.64-0.92) and intracranial hemorrhage (HR, 0.54, 95% CI 0.38-0.77). Among patients with a history of intracranial hemorrhage, the use of NOACs versus VKAs was associated with reduced risks of stroke (HR, 0.81, 95% CI 0.68-0.95), all-cause death (HR, 0.68, 95% CI 0.49-0.94), and intracranial hemorrhage (HR, 0.66, 95% CI 0.51-0.84). Compared with VKAs, the use of NOACs exhibited superior efficacy and safety outcomes in AF patients with previous stroke/TIA, and the use of NOACs was associated with reduced risks of stroke, all-cause death, and intracranial hemorrhage in patients with a history of intracranial hemorrhage.

Abstract
Venous thromboembolism (VTE) is a common complication after intracranial hemorrhage (ICH); the incidence has been reported to vary between 18% to 50% for deep vein thrombosis and between 0.5% to 5% for pulmonary embolism (PE). According to current clinical practice guidelines, patients with acute VTE should receive anticoagulant treatment for at least 3 months in the absence of contraindications. Anticoagulant treatment reduces mortality, prevents early recurrences and improves long-term outcome in patients with acute VTE. However, recent ICH is an absolute contraindication for anticoagulant treatment due to the potential increased risk of hematoma expansion or recurrent ICH. Hematoma expansion occurs in approximately a third of patients within 24 h following the diagnosis of a spontaneous ICH. The risk for recurrent ICH depends on patients' features as well as on the feature of index ICH. Limited evidence is available on the risks of therapeutic anticoagulation started shortly after ICH. Expert consensus around the introduction of therapeutic anticoagulation suggests delaying therapeutic anticoagulation for at least 2 weeks after spontaneous ICH, until the risk re-bleeding becomes acceptable. Vena cava filters should be inserted to reduce the risk for (non) fatal PE until therapeutic anticoagulation can be started; antithrombotic prophylaxis should be started as soon as possible to avoid recurrent VTE after vena cava filter insertion. For patients presenting PE with hemodynamic compromise, percutaneous embolectomy should be considered. Most patients will be able to receive anticoagulant treatment within 4 weeks following spontaneous ICH; direct oral anticoagulants are probably the treatment of choice for those ICH patients tolerating anticoagulant treatment.

[PMID: 33294148 PMCID: PMC7705193 DOI: 10.1177/2040622320974853] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2020] [Accepted: 10/29/2020] [Indexed: 01/01/2023] Open
Abstract
Aim: The aim of this study was to establish whether non-vitamin K antagonist oral anticoagulants (NOACs) are superior to warfarin in preventing stroke recurrence for atrial fibrillation (AF) patients with an ischemic or hemorrhagic stroke at the baseline. Methods: From 1 January 2009 to 31 December 2017, stroke patients with AF treated with oral anticoagulants in the National Health Insurance Research Database in Taiwan were enrolled. The study was retrospective cohort design. Outcome measures were ischemic and hemorrhagic stroke recurrence. The Cox proportional hazard model was used to obtain the hazard ratio (HR). Results: In total, 39,840 stroke patients with AF treated with NOAC and 42,583 treated with warfarin were identified. NOACs were superior to warfarin in preventing all recurrent stroke [adjusted HR: 0.67, 95% confidence interval (CI), 0.63–0.71, p < 0.001]. Results for the ischemic stroke population were the same as that for all types for stroke (adjusted HR: 0.66, 95% CI, 0.62–0.70, p < 0.001). For the hemorrhagic stroke population, NOACs were equivalent to warfarin in preventing ischemic stroke (adjusted HR: 1.11, 95% CI, 0.86–0.43, p < 0.001), but NOACs were superior to warfarin in preventing hemorrhagic stroke (adjusted HR: 0.64, 95% CI, 0.55–0.74, p < 0.001). Conclusions: NOACs were generally superior to warfarin in terms of efficacy and safety in previous stroke patients. The robustness of our findings was verified and should add new information to current recommendations for Asian stroke patients in selecting NOACs.

Abstract
BACKGROUND Intracranial hemorrhage (ICH) is associated with severe prognosis and recurrent risk. This impacts on the decision to resume anticoagulation in atrial fibrillation (AF) or venous thromboembolism (VTE) patients. Purpose of our study is to evaluate the incidence rate of recurrent ICH in patients with AF or VTE resuming anticoagulation after a first ICH episode. METHODS We report data of two cohorts of AF or VTE after a first ICH. The Vitamin K antagonist (VKA) cohort (166 patients) derives from CHIRONE Study, the direct oral anticoagulant (DOAC) cohort (178 patients) derives from START2-Register RESULTS: The clinical characteristics of the two cohort are similar with the exception of more prevalence of history of previous stroke/TIA in DOAC patients with respect to VKA (p = 0.02) and serum creatinine levels>1.5 mg/dL in VKA patients with respect to DOAC(p = 0.0001). The index ICH was spontaneous in 66.4% and in 33.7% among DOAC and VKAs cohort respectively (p = 0.0001). During follow-up, 14 recurrent ICH were recorded; 9 (rate 2.5 × 100 patient-years) in VKA and 5 (rate 1.3 × 100 patient-years) in DOAC (Relative Risk 1.9; 95% CI 0.6-7.4; p = 0.2). The univariate logistic regression analysis showed that patients with recurrent ICH were more frequently males, hypertensive, with a history of previous Stroke/TIA and older than patients without recurrence. VKA patients showed a higher risk of recurrence with respect to DOAC patients (OR 1.9;95% CI 0.7-6.7). CONCLUSIONS A trend toward fewer ICH recurrences was detected among DOACs patients in comparison to the previously reported rate of patients on warfarin.

Abstract
INTRODUCTION Oral anticoagulants (OAC) reduce stroke/systemic embolism and mortality risks in atrial fibrillation (AF). However, there is an inherent bleeding risk with OAC, where intracranial hemorrhage (ICH) is the most feared, disabling, and lethal complication of this therapy. Therefore, the optimal management of OAC-associated ICH is not well defined despite multiple suggested strategies. AREAS COVERED In this review, the authors describe the severity and risk factors for OAC-associated ICH and the associated implications for using DOACs in AF patients. We also provide an overview of the management of OAC-associated ICH and treatment reversal strategies, including specific and nonspecific reversal agents as well as a comprehensive summary of the evidence about the resumption of DOAC and the optimal timing. EXPERT OPINION In the setting of an ICH, supportive care/measures are needed, and reversal of anticoagulation with specific agents (including administration of vitamin K, prothrombin complex concentrates, idarucizumab and andexanet alfa) should be considered. Most patients will likely benefit from restarting anticoagulation after an ICH and permanently withdrawn of OAC is associated with worse clinical outcomes. Although the timing of OAC resumption is still under debate, reintroduction after 4-8 weeks of the bleeding event may be possible, after a multidisciplinary approach to decision-making.

Abstract
BACKGROUND Evidence of adverse clinical outcomes for non-vitamin K antagonist oral anticoagulant (NOACs) and warfarin in patients with atrial fibrillation (AF) and diabetes mellitus are limited. We investigated the effectiveness, safety, and major adverse limb events for NOACs versus warfarin among diabetic AF patients. METHODS In this nationwide retrospective cohort study collected from Taiwan National Health Insurance Research Database, we identified a total of 20,967 and 5812 consecutive AF patients with diabetes taking NOACs and warfarin from June 1, 2012, to December 31, 2017, respectively. We used propensity-score stabilized weighting to balance covariates across study groups. RESULTS NOAC was associated with a lower risk of major adverse cardiovascular events (MACE) (adjusted hazard ratio (aHR):0.88; [95% confidential interval (CI) 0.78-0.99]; P = 0.0283), major adverse limb events (MALE) (aHR:0.72;[95% CI 0.57-0.92]; P = 0.0083), and major bleeding (aHR:0.67;[95% CI 0.59-0.76]; P < 0.0001) compared to warfarin. NOACs decreased MACE in patients of ≥ 75 but not in those aged < 75 years (P interaction = 0.01), and in patients with ischemic heart disease (IHD) compared to those without IHD (P interaction < 0.01). For major adverse limb events, the advantage of risk reduction for NOAC over warfarin persisted in high risk subgroups including age ≥ 75 years, chronic kidney disease, IHD, peripheral artery disease, or use of concomitant antiplatelet drugs. CONCLUSION Among diabetic AF patients, NOACs were associated with a lower risk of thromboembolism, major bleeding, and major adverse limb events than warfarin. Thromboprophylaxis with NOACs should be considered in the diabetic AF population with a high atherosclerotic burden.

Abstract
Background and Purpose- Warfarin is associated with a better net clinical benefit compared with no treatment in patients with nonvalvular atrial fibrillation (AF) and history of intracranial hemorrhage (ICH). There are limited data on nonvitamin K antagonist oral anticoagulants (NOACs) in these patients, especially in the Asian population. We aimed to compare the effectiveness and safety of NOACs to warfarin in a large-scale nationwide Asian population with AF and a history of ICH. Methods- Using the Korean Health Insurance Review and Assessment database from January 2010 to April 2018, we identified patients with oral anticoagulant naïve nonvalvular AF with a prior spontaneous ICH. For the comparisons, warfarin and NOAC groups were balanced using propensity score weighting. Ischemic stroke, ICH, composite outcome (ischemic stroke+ICH), fatal ischemic stroke, fatal ICH, death from composite outcome, and all-cause death were evaluated as clinical outcomes. Results- Among 5712 patients with AF with prior ICH, 2434 were treated with warfarin and 3278 were treated with NOAC. Baseline characteristics were well-balanced after propensity score weighting (mean age 72.5 years and CHA2DS2-VASc score 4.0). Compared with warfarin, NOAC was associated with lower risks of ischemic stroke (hazard ratio [HR], 0.77 [95% CI, 0.61-0.97]), ICH (HR, 0.66 [95% CI, 0.47-0.92]), and composite outcome (HR, 0.73 [95% CI, 0.60-0.88]). NOAC was associated with lower risks of fatal stroke (HR, 0.54 [95% CI, 0.32-0.89]), death from composite outcome (HR, 0.53 [95% CI, 0.34-0.81]), and all-cause death (HR, 0.83 [95% CI, 0.69-0.99]) than warfarin. NOAC showed nonsignificant trends toward to reduce fatal ICH compared with warfarin (HR, 0.47 [95% CI, 0.20-1.03]). Conclusions- NOAC was associated with a significant lower risk of ICH and ischemic stroke compared with warfarin. NOAC might be a more effective and safer treatment option for Asian patients with nonvalvular AF and a prior history of ICH.

Abstract
Bleeding is the most common complication of anticoagulant use. The evaluation and management of the bleeding patient is a core competency of emergency medicine. As the prevalence of patients receiving anticoagulant agents and variety of anticoagulants with different mechanisms of action, pharmacokinetics, indications, and corresponding reversal agents increase, physicians and other clinicians working in the emergency department require a current and nuanced understanding of how best to assess, treat, and reverse anticoagulated patients. In this project, we convened an expert panel to create a consensus decision tree and framework for assessment of the bleeding patient receiving an anticoagulant, as well as use of anticoagulant reversal or coagulation factor replacement, and to address controversies and gaps relevant to this topic. To support decision tree interpretation, the panel also reached agreement on key definitions of life-threatening bleeding, bleeding at a critical site, and emergency surgery or urgent invasive procedure. To reach consensus recommendations, we used a structured literature review and a modified Delphi technique by an expert panel of academic and community physicians with training in emergency medicine, cardiology, hematology, internal medicine/thrombology, pharmacology, toxicology, transfusion medicine and hemostasis, neurology, and surgery, and by other key stakeholder groups.
