High brain natriuretic peptide level is associated with severe stroke in patients taking oral anticoagulants: A sub-analysis of the PASTA registry study. J Neurol Sci 2024; 458:122935. [PMID: 38368640 DOI: 10.1016/j.jns.2024.122935] [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: 12/07/2023] [Revised: 02/02/2024] [Accepted: 02/13/2024] [Indexed: 02/20/2024]
Abstract
BACKGROUND Brain natriuretic peptides (BNP) are an important diagnostic and prognostic marker in patients with heart failure. However, the relationship between BNP levels and stroke severity in patients with atrial fibrillation (AF) remains unelucidated. In this study, we aimed to investigate the association between stroke severity at admission and BNP levels. METHODS In this prospective observational study, we used data from 513 patients with AF and acute ischemic stroke treated with oral anticoagulants (OAC) registered in the Multicenter Prospective Analysis of Stroke Patients Taking Oral Anticoagulants study. The patients were divided into two groups: high-BNP (≥200 pg/mL) and low-BNP level (<200 pg/mL) groups. We compared the clinical characteristics between the two groups and determined the effect of BNP levels on stroke severity on admission. RESULTS Among the 513 enrolled patients, 248 (females, n = 30; median age, 82 years) and 265 (females, n = 76; median age, 71 years) were assigned to the high- and low-BNP level groups, respectively. The high-BNP level group had a higher proportion of patients with severe stroke (National Institutes of Health Stroke Scale score, ≥10) on admission (49.2% vs. 32.8%, p = 0.002) and major vessel occlusion (57.5% vs. 39.2%, p < 0.0001) than that had by the low-BNP level group. Multivariate analysis showed that high BNP level was independently associated with severe stroke on admission (odds ratio 1.07, 95% confidence interval 1.00-1.15; p = 0.0478). CONCLUSIONS High BNP level compared with low BNP level was associated with severe stroke and major vessel occlusion, even before OAC treatment.

Abstract
PURPOSE To compare effectiveness of different treatments for atrial fibrillation (AF) patients who were scheduled for cardioversion (CV) or ablation (CA) presenting with left atrium appendage (LAA) thrombus despite chronic oral anticoagulation therapy (OAC). METHODS This was a retrospective cohort study. We analyzed 2014-2019 medical records of patients scheduled for CV or CA of AF who were diagnosed with LAA thrombus despite optimal OAC and had a follow-up transesophageal echocardiogram (TOE). Changes in treatment were divided into the following groups: switch to a drug with different mechanism of action, switch to a drug with similar mechanism of action, initiation of combination therapy, or deliberate no change in treatment. Patients with contraindications to non-vitamin K antagonists were excluded from the analysis. RESULTS We analyzed data of 129 patients comprising 181 cycles of treatment. The overall effectiveness of LAA thrombus dissolution was 51.9% regardless of the number of cycles and 42.6% for the first cycle of treatment. Any change of treatment was more effective than deliberate no change-OR 2.97 [95% CI: 1.07-8.25], P = 0.031, but no particular strategy seemed to be more effective than the other. Left atrium area (OR 0.908 [95% CI: 0.842-0.979]) and number of treatment cycles (OR 0.457 [95% CI: 0.239-0.872]) were both adversely related to thrombus resolution. There was one ischemic and three bleeding adverse events during the treatment. CONCLUSION LAA thrombus resolution in patients already on OAC may require a change of previous OAC treatment but the overall effectiveness of dissolution seems to be about 50%.

Abstract
Background Left atrial appendage closure (LAAC) is considered a valid alternative for the prevention of thromboembolic stroke in patients with persistent left atrial appendage thrombus (LAAT) despite adequate anticoagulation. However, the data on LAAC using the LAmbre device for patients with LAAT is limited. This study was performed to explore efficacy and safety as well as to share the experience of the modified LAAC procedure with the LAmbre device. Materials and methods A total of 7 patients with persistent LAAT despite adequate anticoagulation underwent modified LAAC with the LAmbre device between November 2019 and April 2022. Transesophageal echocardiography was performed 3 months postoperatively to detect device-related thrombosis and peridevice leak. The patients' clinical events were evaluated during the perioperative and follow-up periods. Results The median age, CHA2DS2-VASc score, and HAS-BLED score of all patients were 71 [53-73], 3 [2-4], and 2 [2-3], respectively. In the procedure, a cerebral protection system was used in two patients. LAAC with the LAmbre device was successfully performed in all patients without perioperative events. During the median follow-up of 383 [325-865] days, postoperative transesophageal echocardiography was performed in six (85.7%) patients. Device-related thrombosis was detected in one (16.7%) patient, and no significant peridevice leak was observed. No thromboembolic event or bleeding event occurred in any patients. Conclusion LAAC with the LAmbre device is effective and safe when performed by experienced operators in highly selected patients with LAAT after adequate anticoagulation.

Abstract
Left atrial appendage thrombus (LAAT) is the main cause of cardioembolism in patients with nonvalvular atrial fibrillation (AF). Emerging evidence indicates that direct oral anticoagulants (DOACs) may be a preferred, safer choice for patients with LAAT. However, current guidelines indicate vitamin K antagonist (VKA) as the preferred treatment for LAAT. We conducted a meta-analysis to compare the efficacy of VKA and DOAC for the treatment of LAAT. Methods: The search was conducted in the PubMed, Embase, Google Scholar, and Cochrane Library databases from inception to July 2022, with the language restricted to English. A first analysis was conducted to evaluate the risk of LAAT under VKA or DOAC treatment. A second analysis was conducted to compare the resolution of LAAT under VKA and DOAC treatment. Results: In 13 studies comparing LAAT incidence rates under VKA and DOAC treatment, significant superiority of DOAC was detected (pooled RR = 0.65, 95% CI = 0.47–0.90, p = 0.009) with moderate heterogeneity being identified in the pooled studies. In 13 studies comparing LAAT resolution under VKA and DOAC use, treatment with DOAC exhibited a significantly increased probability of LAAT resolution compared with VKA (pooled odds ratio = 1.52, 95% CI = 1.02–2.26, p = 0.040). Conclusions: This meta-analysis suggests a superiority of DOAC over VKA with respect to LAAT incidence in people with AF and the likelihood of LAAT resolution. Due to their established safety profile, DOAC is a preferable choice for anticoagulation, although further randomized controlled studies are warranted to provide further evidence of their suitability as a new recommended treatment.

Abstract
BACKGROUND Data on long-term outcomes of catheter ablation (CA) for atrial fibrillation (AF) in outside of clinical trials settings are sparse. OBJECTIVE We aimed to assess outcomes and readmissions at 1 year following admission for CA for AF. METHODS Utilizing the Nationwide Readmissions Database (2016-2018), we identified patients with CA among all patients with a primary admission diagnosis of AF, and a control group by propensity score match adjusted for age, sex, comorbidities, CHA₂DS₂-VASc scores, and the hospital characteristics. The primary outcome was a composite of unplanned heart failure (HF), AF and stroke-related readmissions and death at 1 year, and secondary outcomes were hospital outcomes and all-cause readmission rates. RESULTS The study cohort consisted of 29,771 patients undergoing CA and 63,988 controls. Patients undergoing CA were younger with lower CHA₂DS₂-VASc scores and less comorbidities. Over a follow-up of 170 ±1.1 days, the primary outcome occurred in 5.2% in CA group and 6.0% of controls (hazard ratio [HR] and 95% confidence interval [CI]: 0.86 [0.76-0.94], p = 0.002). CA affected AF and stroke related readmission, but showed no effect on HF and mortality outcome.Male sex (HR: 0.83 [0.74-0.94], p = 0.03), younger age (HR: 0.71 [0.61-0.83], p<0.001], and lower CHA₂DS₂-VASc scores (HR: 0.68 [0.55-0.84], p<0.001) were associated with lower risk of primary outcome with CA. CONCLUSION In this study, CA for AF was associated with significantly lower AF and stroke-related admissions, but not to HF or all cause readmission. Better outcomes were seen among males, younger patients and in patients with less comorbidities and low CHA₂DS₂-VASc scores. This article is protected by copyright. All rights reserved.

Characteristics of non-valvular atrial fibrillation with left atrial appendage thrombus who are undergoing appropriate oral anticoagulation therapy. THE INTERNATIONAL JOURNAL OF CARDIOVASCULAR IMAGING 2022; 38:941-951. [PMID: 38819730 DOI: 10.1007/s10554-021-02403-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/26/2021] [Accepted: 08/31/2021] [Indexed: 12/25/2022]
Abstract
We investigated the characteristics of patients with non-valvular atrial fibrillation (NVAF) and left atrial (LA) appendage (LAA) thrombus who had been given appropriate oral anticoagulation therapy. We studied 737 NVAF patients who were scheduled for catheter ablation or electrical cardioversion. All patients received appropriate oral anticoagulation therapy for at least 3 weeks prior to echocardiography in accordance with the guidelines. Whether LAA thrombus was present or absent on transesophageal echocardiography (TEE) was determined by at least three senior echocardiologists. LAA thrombi were observed in 22 patients (3.0%). Multivariate logistic regression analysis showed that LAA flow and LA volume index were both independent predictors of LAA thrombus formation; however, LAA flow (≤ 18 cm/s) was indicated as a more powerful predictor. Moreover, the prevalence of LAA thrombus formation in patients with NVAF without LA enlargement (LA volume index ≤ 34 mL/m2) was extremely rare (0.4%). LAA thrombus formation in patients with a mildly dilated LA volume index of 34-49.9 mL/m2 and paroxysmal AF was also extremely rare (0.0%). LAA flow is strongly associated with LAA thrombus formation, even in NVAF patients treated with appropriate oral anticoagulation therapy. Augmented oral anticoagulation therapy or transcatheter or surgical LAA closure should be considered for such patients, especially for those with an LAA flow < 18 cm/s. Furthermore, TEE for evaluating LAA thrombus before catheter ablation or electrical cardioversion may be unnecessary for NVAF patients who are undergoing appropriate oral anticoagulation therapy, depending on LA size.

Relationship of warfarin versus DOACs with thrombogenic milieu in the left atrium among patients with nonvalvular atrial fibrillation. Echocardiography 2022; 39:483-489. [PMID: 35137446 DOI: 10.1111/echo.15319] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2021] [Revised: 01/25/2022] [Accepted: 01/30/2022] [Indexed: 11/28/2022] Open
Abstract
BACKGROUND Thrombogenic milieu (TM) within the left atrium plays a pivotal role in the pathogenesis of thromboembolic events, for which anticoagulation treatment is indicated typically on the mandatory basis. Little is known, however, about which regimen of anticoagulation, warfarin or direct oral anticoagulants (DOACs), is more likely associated with TM. We evaluated relative relationship of the two treatment options with concurrently-observed TM in patients with nonvalvular atrial fibrillation (AF) who underwent transesophageal echocardiography. METHODS TM was defined as the presence of either left atrial spontaneous echo contrast (SEC) or thrombus, or both. To determine which regimen was more likely related to TM, we firstly compared the prevalence of TM in 208 patients taking warfarin (Warfarin group) versus 486 patients taking DOACs (DOAC group); and secondly, did the same analysis after propensity score matching. RESULTS Warfarin group was more likely associated with TM compared with DOAC group (46% vs 29%, p < 0.001). Similar findings were observed for dense SEC (18% vs 7%, p < 0.001) and thrombus (4% vs 1%, p = 0.057). The propensity score matching (198 patients for each group), where several baseline parameters were matched including age, gender, chronicity of AF, estimated glomerular filtration rate and B-type natriuretic peptide as well as the left ventricular ejection fraction, resulted in similar findings to the original groups (TM, 47% vs 32%, p = 0.002; dense SEC, 18% vs 7%, p = 0.001; thrombus, 4% vs 1%, p = 0.047). CONCLUSIONS This study may strengthen the data on randomized trials that DOACs are superior to warfarin in preventing thromboembolic events in nonvalvular AF patients. Further studies are required to elucidate the details behind this difference.

Abstract
Background NT Pro‐BNP is a blood marker secreted by cardiomyocytes. Myocardial stretch is the main factor to stimulate NT Pro‐BNP secretion in cardiomyocytes. NT Pro‐BNP is an important risk factor for cardiac dysfunction, stroke, and pulmonary embolism. So does atrial myocyte stretching occur when patients have atrial fibrillation (AF)? Whether atrial muscle stretch induced by AF leads to increased NT Pro‐BNP remains unclear. The purpose of this study is to investigate the relationship between NT Pro‐BNP and AF. Hypothesis AF can cause changes in myocardial tension. Changes in myocardial tension may lead to increased secretion of NT Pro‐BNP. We hypothesize that NT Pro‐BNP may increase in AF with or without LAD enlargement. Methods This clinical study is an observational study and has been approved by the Ethics Committee of the First Affiliated Hospital of Xi'an Jiaotong University. Ethical approval documents is attached. The study retrospectively reviewed 1345 patients with and without AF. After excluding 102 patients who were not eligible, the final total sample size was 1243 cases: AF group 679 patients (378, 55.7% males) and non‐AF group 564 patients (287, 50.8% males). NT Pro‐BNP was observed in AF group and non‐AF group with or without LAD. After adjusting for age, gender, BMI, left atrial diameter, hypertension, diabetes, coronary heart disease, and cerebral infarction, NT Pro‐BNP remains statistically significant with AF. Conclusion NT Pro‐BNP can be used as a risk predictor of AF with or without left atrial enlargement.

Abstract
BACKGROUND The prevalence of left atrial (LA) thrombus in patients with atrial fibrillation (AF) or atrial flutter (AFL) on guideline-directed anticoagulation is not well known, yet this may inform transesophageal echocardiogram (TEE) use before cardioversion or catheter ablation. OBJECTIVES The purpose of this study was to quantify LA thrombus prevalence among patients with AF/AFL on guideline-directed anticoagulation and to identify high-risk subgroups. METHODS EMBASE, MEDLINE, and CENTRAL were systematically searched from inception to July 2020 for studies reporting on LA thrombus prevalence among patients with AF/AFL undergoing TEE following at least 3 weeks of continuous therapeutic oral anticoagulation with vitamin K antagonists (VKAs) or direct oral anticoagulants (DOACs). Meta-analysis was performed using random effects models. RESULTS Thirty-five studies describing 14,653 patients were identified. The mean-weighted LA thrombus prevalence was 2.73% (95% confidence interval [CI]: 1.95% to 3.80%). LA thrombus prevalence was similar for VKA- and DOAC-treated patients (2.80%; 95% CI: 1.86% to 4.21% vs. 3.12%; 95% CI: 1.92% to 5.03%; p = 0.674). Patients with nonparoxysmal AF/AFL had a 4-fold higher LA thrombus prevalence compared with paroxysmal patients (4.81%; 95% CI: 3.35% to 6.86% vs. 1.03%; 95% CI: 0.52% to 2.03%; p < 0.001). LA thrombus prevalence was higher among patients undergoing cardioversion versus ablation (5.55%; 95% CI: 3.15% to 9.58% vs. 1.65%; 95% CI: 1.07% to 2.53%; p < 0.001). Patients with CHA2DS2-VASc scores ≥3 had a higher LA thrombus prevalence compared with patients with scores ≤2 (6.31%; 95% CI: 3.72% to 10.49% vs. 1.06%; 95% CI: 0.45% to 2.49%; p < 0.001). CONCLUSIONS LA thrombus prevalence is high in subgroups of anticoagulated patients with AF/AFL, who may benefit from routine pre-procedural TEE use before cardioversion or catheter ablation.

ACTA ACUST UNITED AC 2021; 61:17-22. [PMID: 34112071 DOI: 10.18087/cardio.2021.5.n1463] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2020] [Revised: 01/12/2021] [Accepted: 01/29/2021] [Indexed: 11/18/2022]
Abstract
Aim To compare the incidence of cardiovascular complications (CVC) in patients with persistent atrial fibrillation (AF) following thrombus dissolution in the left atrial appendage (LAA) and in patients with persistent AF without preceding LAA thrombosis.Material and methods The main group included 43 patients who had been diagnosed with LAA thrombosis on the first examination, transesophageal echocardiography, and who showed dissolution of the thrombus on a repeated study performed after 7.1+2.0 weeks of the anticoagulant treatment. The control group consisted of 123 patients with a risk score >0 for men without LAA thrombosis and score >1 for women without LAA thrombosis according to the CHA2DS2‑VASc scale. The patients were followed up for 47.3±17.9 months. The following unfavorable outcomes were recorded: all-cause mortality, ischemic stroke or systemic thromboembolism, hemorrhagic stroke or severe bleeding, and myocardial infarction (MI).Results Unfavorable clinical outcomes were observed in 39.5 % of patients in the main group and in 3.3 % of patients in the control group (p<0.001). Furthermore, the incidence of ischemic stroke (relative risk (RR), 12.9; 95 % confidence interval (CI), 2.89-57.2), and MI (RR, 5.72; 95 % CI, 1.09-30.1) was higher in the main group. However, the number of MI cases in both groups and the number of stroke cases in the control group increased during the entire follow-up period, while the number of stroke cases rapidly increased only during the first year of follow-up.Conclusion In patients with persistent AF, the risk of CVC after LAA thrombus dissolution remains significantly higher than in patients with AF without LAA thrombosis.

Abstract
BACKGROUND AND OBJECTIVES Prior studies have shown that stroke patients treated with percutaneous left atrial appendage occlusion (LAAO) for non-valvular atrial fibrillation (NVAF) experience better outcomes than similar patients treated with warfarin. We investigated the impact of percutaneous left atrial appendage closure on post-stroke neurological outcomes in NVAF patients, compared with non-vitamin K antagonist oral anticoagulant (NOAC) therapy. METHODS Medical records for 1,427 patients in multiple registries and for 1,792 consecutive patients at 6 Korean hospitals were reviewed with respect to LAAO or NOAC treatment. Stroke severity in patients who experienced ischemic stroke or transient ischemic attack after either treatment was assessed with modified Rankin Scale (mRS) scoring at hospital discharge and at 3 and 12 months post-stroke. RESULTS mRS scores were significantly lower in LAAO patients at 3 (p<0.01) and 12 months (p<0.01) post-stroke, despite no significant differences in scores before the ischemic cerebrovascular event (p=0.22). The occurrences of disabling ischemic stroke in the LAAO and NOAC groups were 36.7% and 44.2% at discharge (p=0.47), 23.3% and 44.2% at 3 months post-stroke (p=0.04), and 13.3% and 43.0% at 12 months post-stroke (p=0.01), respectively. Recovery rates for disabling ischemic stroke at discharge to 12 months post-stroke were significantly higher for LAAO patients (50.0%) than for NOAC patients (5.6%) (p<0.01). CONCLUSIONS Percutaneous LAAO was associated with more favorable neurological outcomes after ischemic cerebrovascular event than NOAC treatment.

Abstract
Left atrial appendage thrombus (LAAT) may be detected by transesophageal echocardiography (TOE) in patients with atrial fibrillation (AF) despite continuous anticoagulation therapy. We examined the factors predisposing to LAAT in patients treated with the anticoagulants dabigatran and rivaroxaban. We retrospectively evaluated 1,256 AF patients from three centres who underwent TOE before electrical cardioversion (n = 611, 51.4%) or catheter ablation (n = 645, 48.6%) from January 2013 to December 2019 and had been on at least three weeks of continuous dabigatran (n = 603, 48%) or rivaroxaban (n = 653, 52%) therapy. Preprocedural TOE diagnosed LAAT in 51 patients (4.1%), including 30 patients (5%) treated with dabigatran and 21 patients (3.2%) treated with rivaroxaban (p=0.1145). In multivariate logistic regression, predictors of LAAT in patients treated with dabigatran were non-paroxysmal AF (vs. paroxysmal AF) (OR = 6.2, p=0.015), heart failure (OR = 3.22, p=0.003), and a eGFR <60 ml/min/1.73 m2 (OR = 2.65, p=0.012); the predictors in patients treated with rivaroxaban were non-paroxysmal AF (vs. paroxysmal AF) (OR = 5.73, p=0.0221) and heart failure (OR = 3.19, p=0.116). In ROC analysis of the dabigatran group, the area under the curve (AUC) for the CHA2DS2-VASc-RAF score was significantly higher (0.78) than those for the CHADS2, CHA2DS2-VASc, and R2CHADS2 scores (0.67, 0.70, and 0.72, respectively). In the rivaroxaban group, the CHA2DS2-VASc-RAF score also performed significantly better (AUC of 0.77) than the CHADS2, CHA2DS2-VASc, and R2CHADS2 scores (AUC of 0.66, 0.64, and 0.67, respectively). The risk of LAAT was the same for patients in both treatment groups. In all patients, non-paroxysmal AF or heart failure, and in patients treated with dabigatran an eGFR <60 ml/min/1.73 m2, were independent predictors of LAAT. The new CHA2DS2-VASc-RAF scale had the highest predictive value for LAAT in the entire study population.

Abstract
A 78-year-old male with a history of a cardiac embolic stroke due to persistent AF and cerebral bleeding (CHADS2 score 4, HAS-BLED score 4) was referred to our hospital to implant a left atrial appendage (LAA) closure (LAAC) device. A trans esophageal echocardiography was performed and a high echoic lesion that was difficult to differentiate the spontaneous echo contrast or thrombus was found in the LAA cavity. After isoproterenol infusion, a high echoic lesion disappeared and we confirmed that it was not an LAA thrombus. Successful LAAC device implantation was performed without any thromboembolic events.

Biomarkers for Predicting Left Atrial or Left Atrial Appendage Thrombus in Anticoagulated Patients with Nonvalvular Atrial Fibrillation. Cardiol Res Pract 2020; 2020:1683142.

Abstract
Purpose Although atrial fibrillation (AF) is often associated with thromboembolic complications, there is no definite biomarker for detecting the presence of thrombi in the left atrial (LA) or left atrial appendage (LAA) in patients with nonvalvular atrial fibrillation (NVAF). Methods NVAF patients who underwent transesophageal echocardiography (TEE) to evaluate LA/LAA thrombus and spontaneous echo contrast (SEC) before AF ablation were included. Multivariate logistic regression and receiver operating characteristic curve (ROC) analyses were performed to explore the independent risk factors of LA/LAA thrombus and indicate the best cutoff point. Results Of the 260 consecutive subjects (mean age: 63.67 ± 9.39 years; 42% women), 45 (17.3%) patients were with LA/LAA thrombus, 131 (50.4%) were with SEC, and 84 (32.3%) were with neither thrombus nor SEC. The results of multivariate logistic regression analysis showed that N-terminal pro-B-type natriuretic peptide (NT-proBNP) (OR, 2.179; 95% CI: 1.191–3.987; p=0.012) and red cell distribution width (RDW) (OR, 2.398; 95% CI: 1.075–5.349; p=0.033) were independently correlated with the presence of LA/LAA thrombus but not D-dimer (OR, 0.999; 95% CI: 0.998–1.000; p=0.210). When all patients were divided into four groups based on the combination between RDW (cutoff value: 12.95%) and NT-proBNP levels (cutoff value: 368.9 ng/L), the rate of LA/LAA thrombus was the highest in the high RDW and NT-proBNP group. Conclusion In anticoagulation patients with NVAF, elevated NT-proBNP and RDW are related to LA/LAA thrombus. Therefore, these might be considered as useful prognostic markers in the management and treatment of NVAF patients.

Abstract
Aims Recently, B‐type natriuretic peptide (BNP) has been attracting attention as a predictor of stroke in patients with atrial fibrillation or those with prior stroke experience. However, the association between BNP and stroke has not been examined in patients with chronic heart failure (CHF). In the current study, we assessed whether BNP is associated with future occurrence of stroke in patients with CHF. Methods and results We prospectively studied 1803 consecutive patients who were admitted for decompensated HF and assessed the predictive value of circulating BNP levels for occurrence of post‐discharge stroke. A total of 69 (3.8%) patients experienced a stroke (the stroke group) during the post‐discharge follow‐up period of a median of 1150 days. The stroke group showed a higher CHADS2 score. With respect to past medical history, the stroke group had a higher prevalence of arterial hypertension, atrial fibrillation, prior stroke, and chronic kidney disease. Echocardiographic parameters showed no significant differences between the two groups. In contrast, BNP levels were significantly higher in the stroke group than in the non‐stroke group (452.1 vs. 222.7 pg/mL, P < 0.001). Multivariate Cox proportional hazard analysis indicated that BNP levels were independently associated with post‐discharge stroke (hazard ratio 2.636, 95% confidence interval 1.595–4.357, P < 0.001). The survival classification and regression tree analysis revealed that the accurate cut‐off point of BNP in predicting post‐discharge stroke was 187.7 pg/mL. We added high BNP level (BNP ≥ 180 pg/mL) as one point to CHADS2 score. The BNP‐added CHADS2 score was compared with CHADS2 score alone by using c‐statistics. The areas under the curve of CHADS2 score, BNP, and BNP‐added CHADS2 score were 0.698, 0.616, and 0.723, respectively. The predictive value of BNP‐added CHADS2 score was higher compared with those of CHADS2 score (P = 0.026). Conclusions The assessment of BNP may predict the occurrence of stroke in CHF patients used alone or in combination with established CHADS2 score.

Santos J, António N, Rocha M, Fortuna A. Impact of direct oral anticoagulant off-label doses on clinical outcomes of atrial fibrillation patients: A systematic review. Br J Clin Pharmacol 2020; 86:533-547. [PMID: 31631392 DOI: 10.1111/bcp.14127] [Citation(s) in RCA: 61] [Impact Index Per Article: 15.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2019] [Revised: 08/14/2019] [Accepted: 09/07/2019] [Indexed: 12/23/2022] Open
Abstract
AIMS Worldwide observational studies are evidencing discordance between guidelines and real-world practice regarding direct oral anticoagulant drug (DOAC) doses. This systematic review summarizes and evaluate DOACs use in real-world practice. METHODS This review was performed following the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines searching PubMed (MEDLINE) and Medscape databases. RESULTS Data from 75 studies showed that most of the patients treated with DOACs for stroke prevention in atrial fibrillation received doses in accordance to the guidelines. However, a significant number of patients received off-label doses (25-50% in most of the studies evaluated). DOAC overdosing was associated with increased all-cause mortality and worse bleeding events while underdosing was associated with increased cardiovascular hospitalization and, particularly for apixaban, with a nearly 5-fold increased risk of stroke. CONCLUSION Patients prescribed with off-label DOAC doses did not receive the full benefit of anticoagulation and presented an increased risk of stroke, bleeding and/or adverse effects.

Comparison of transesophageal echocardiography findings after different anticoagulation strategies in patients with atrial fibrillation: a systematic review and meta-analysis. BMC Cardiovasc Disord 2019; 19:261. [PMID: 31771529 PMCID: PMC6878716 DOI: 10.1186/s12872-019-1209-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2019] [Accepted: 09/26/2019] [Indexed: 11/12/2022] Open
Abstract
Background High risk of embolic events exists in both patients with chronic atrial fibrillation (AF) and patients in the perioperative period of ablation (effective treatment for AF). Therefore, anticoagulant therapy is important. Oral anticoagulants can be divided into two major categories: vitamin K antagonists (VKAs) and non-vitamin K antagonist oral anticoagulants (NOACs). VKAs, represented by warfarin, have been widely used as traditional anticoagulants, whereas NOACs have been used in clinical practice, but their anticoagulant effects and side effects are still the focus of research. We used a meta-analysis to compare the incidence of left atrial thrombi (LAT) between different anticoagulants. Methods We searched PubMed, EMBASE, Web of Science, and the Cochrane Library databases for observational studies that compared the transesophageal echocardiography (TEE) findings for patients treated with NOACs and VKAs. The incidence of LAT and dense spontaneous echocardiographic contrast (dense SEC) were extracted as the basis of the meta-analysis. Results Fifteen studies were included in the meta-analysis. We found that patients anticoagulated with NOACs and VKAs had similar incidence of LAT (OR = 0.74, 95%CI: 0.55–1.00). After excluding the heterogeneous article by sensitivity analysis, we found the incidence of LAT in patients anticoagulated with NOACs is lower than VKAs (OR = 0.59, 95%CI: 0.42–0.84). The results of subgroup analysis showed that the incidence of LAT among three types of NOACs have no significant difference (dabigatran vs. rivaroxaban, OR = 1.16 [0.75, 1.81]; rivaroxaban vs. apixaban, OR = 0.97 [0.54, 1.74]; dabigatran vs. apixaban, OR = 1.09 [0.55, 2.16]). Conclusion Patients anticoagulated with NOACs may have lower incidence of LAT than VKAs. The incidence of LAT among different type of NOACs are similar.

Abstract
Linear endoscopic ultrasound (L-EUS) is mainly performed to assess pancreaticobiliary and mediastinal diseases. In this report, transesophageal observation with L-EUS revealed an LAA thrombus that was not detected by transthoracic echocardiography. This report highlights a novel potential role for L-EUS in the detection of cardiovascular diseases including LAA thrombi.

Abstract
BACKGROUND In atrial fibrillation (AF) patients, the effect of direct oral anticoagulant (DOACs) therapy on the incidence of left atrial appendage thrombus (LAT) remains poorly investigated. This study examined the prevalence and risk factors of LAT in AF patients on DOACs undergoing catheter ablation, and sought an anticoagulation strategy for LAT. Methods and Results: In 407 AF patients on DOACs, transesophageal echocardiography (TEE) was performed 1 day before ablation. If patients had LAT, initial DOACs were switched to dabigatran (300 mg) or warfarin based on their renal function; TEE was repeated after treatment for ≥4 weeks. LAT was detected in 18 patients (4.4%). The prevalence of persistent AF and low-dose treatment/inappropriate dose reduction of DOACs, CHADS2/CHA2DS2-VASc scores, serum N-terminal pro-brain natriuretic peptide levels, and LA dimension/LA volume index significantly increased in patients with LAT vs. those without LAT. AF rhythm on TEE and spontaneous echo contrast also increased in patients with LAT; LA appendage flow velocity decreased. In the multivariate analysis, persistent AF and inappropriately reduced DOAC dose were risk factors for LAT. On repeat TEE, LAT had disappeared in 13 of 16 patients treated with dabigatran and in 2 of 2 patients treated with warfarin. CONCLUSIONS DOACs still carry a finite risk of LAT in AF patients. Inappropriately reduced DOAC dose should be avoided to minimize the thromboembolic risk. Regular-dose dabigatran may have therapeutic efficacy against LAT.

Abstract
This study sought to investigate the safety of percutaneous left atrial appendage (LAA) occlusion for stroke prevention in patients with nonvalvular atrial fibrillation who have LAA thrombus. From October 2010 to October 2016, LAA occlusions were performed in facilities within a Korean multicenter registry in patients without (n = 132) or with (n = 10) LAA thrombus (detected during preprocedural assessments). The incidences of periprocedural complications, including stroke, pericardial tamponade, major bleeding, and device embolization, were assessed and compared between the groups. The incidence of periprocedural complications was not significantly different between patients with and without LAA thrombus (0% vs 5% [6 of 132]; p = 0.49). During the mean 23.2 ± 17.5-month follow-up duration, 7 major adverse cardiac events occurred (1 cardiovascular death, 6 ischemic strokes), but overall event rates were not significantly different between the groups (14% vs 9%; p = 0.47). In conclusion, percutaneous LAA occlusion in nonvalvular atrial fibrillation patients with LAA thrombus may be a safe and feasible alternative to anticoagulation in select patients at a high risk of bleeding or contraindication to anticoagulation, or in whom anticoagulation failed to prevent stroke.

Abstract
BACKGROUND B-type natriuretic peptide (BNP) may be a predictor of stroke risk in patients with nonvalvular atrial fibrillation (NVAF); because heart failure is associated with the incidence of stroke in AF patients. However, limited data exist regarding the association between BNP at baseline and risks of thromboembolic events (TE) and death in NVAF patients. Methods and Results: We prospectively studied 1,013 NVAF patients (725 men, 72.8±9.7 years old) from the Hokuriku-plus AF Registry to determine the relationship between BNP at baseline and prognosis among Japanese NVAF patients. During the follow-up period (median, 751 days); 31 patients experienced TE and there were 81 cases of TE/all-cause death. For each endpoint we constructed receiver-operating characteristic curves that gave cutoff points of BNP for TE (170 pg/mL) and TE/all-cause death (147 pg/mL). Multivariate analysis with the Cox-proportional hazards model indicated that high BNP was significantly associated with risks of TE (hazard ratio [HR] 3.86; 95% confidence interval [CI] 1.83-8.67; P=0.0003) and TE/all-cause death (HR 2.27; 95% CI 1.45-3.56; P=0.0003). Based on the C-index and net reclassification improvement, the addition of BNP to CHA2DS2-VASc statistically improved the prediction of TE. CONCLUSIONS In a real-world cohort of Japanese NVAF patients, high BNP was significantly associated with TE and death. Plasma BNP might be a useful biomarker for these adverse clinical events.

Abstract
Transoesophageal echocardiography (TOE) is frequently performed prior to atrial fibrillation (AF) ablation to exclude left atrial appendage (LAA) thrombus. However, patients undergoing AF ablation are usually anticoagulated, thus making the presence of thrombus unlikely in most cases. This study aimed to determine whether the CHA2DS2VASc scoring system can be used to identify patients that do not require TOE prior to AF ablation. In this single-centre retrospective study, local institutional and primary care databases and electronic patient records were searched to identify patients that had undergone TOE prior to AF ablation. Patient demographics, CHA2DS2VASc score, TOE findings and anticoagulation status were collected for analysis. Over a 7-year period (2008–2014), 332 patients (age 57 ± 10 years; 74% male) underwent TOE prior to proposed AF ablation. CHA2DS2VASc scores of 0, 1, 2 and >2 were found in 39, 34, 15 and 12% of patients, respectively. The prevalence of LAA thrombus was 0.6% (2 patients) and these 2 patients had risk scores of 2 and 4. No patients with a score of 0 or 1 had LAA thrombus. Patients that are classed as low risk by the CHA2DS2VASc score do not require a pre-ablation TOE to screen for LAA thrombus provided they are adequately anticoagulated. This would lead to a significant reduction in health care expenditures by reducing unnecessary TOE requests and thereby improve patient experience.
