Atrial fibrillation type and long-term clinical outcomes in hospitalized patients with heart failure: insight from JROADHF. EUROPEAN HEART JOURNAL. QUALITY OF CARE & CLINICAL OUTCOMES 2024; 10:193-202. [PMID: 38236704 DOI: 10.1093/ehjqcco/qcae005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/27/2023] [Revised: 12/20/2023] [Accepted: 01/16/2024] [Indexed: 05/24/2024]
Abstract
AIMS Atrial fibrillation (AF) type (paroxysmal, persistent, or permanent) is important in determining therapeutic management; however, clinical outcomes by AF type are largely unknown for hospitalized patients with heart failure (HF). METHODS AND RESULTS The Japanese Registry Of Acute Decompensated Heart Failure is a retrospective, multicenter, and nationwide registry of patients hospitalized for acute HF in Japan. Follow-up data were collected up to 5 years after hospitalization. Patients were divided based on diagnosis and AF type into 3 groups [without AF, paroxysmal AF, and sustained AF (defined as a composite of persistent and permanent AF)], and compared the backgrounds and outcomes between the groups. Of 12 895 hospitalized HF patients [mean age: 78 ± 13 years, female: 6077 (47%), and mean left ventricular ejection fraction: 47 ± 17%], 1725 had paroxysmal AF, and 3672 had sustained AF. Compared with patients without AF, sustained AF had a higher risk of the primary composite endpoint of cardiovascular (CV) death or HF hospitalization [hazard ratio (HR): 1.09, 95% confidence interval (CI): 1.01-1.17; P = 0.03], mainly driven by HF hospitalization [HR: 1.16, 95% CI: 1.06-1.26; P < 0.001], whereas the corresponding risk for the primary endpoint in patients with paroxysmal AF was not elevated (HR: 1.03, 95% CI: 0.94-1.13; P = 0.53) after adjustment by multivariable Cox regression analysis. These results were consistent among the subgroups of patients with reduced or preserved ejection fraction (interaction P = 0.74). CONCLUSION Among hospitalized patients with HF, sustained AF, but not paroxysmal AF, was significantly associated with a higher risk for CV death or HF hospitalization, indicating the importance of accounting for AF type in HF patients.

Abstract
Resection of the left atrial appendage reportedly improves blood pressure in patients with hypertension. This study aimed to validate the transcriptional profiles of atrial genes responsible for blood pressure regulation in patients with hypertension as well as to identify the molecular mechanisms in rat biological systems. RNA sequencing data of left atrial appendages from patients with (n = 6) and without (n = 6) hypertension were subjected to unsupervised principal component analysis (PCA). Reduction of blood pressure was reflected by third and ninth principal components PC3 and PC9, and that eighteen transcripts, including endothelin-1, were revealed by PCA-based pathway analysis. Resection of the left atrial appendage in hypertensive rats improved their blood pressure accompanied by a decrease in serum endothelin-1 concentration. Expression of the endothelin-1 gene in the atrium and atrial appendectomy could play roles in blood pressure regulation in humans and rats.

Abstract
BACKGROUND Various treatment approaches for atrial fibrillation (AF) have demonstrated improved health status, yet the significance of these therapeutic interventions in individual patients remains unclear. OBJECTIVE This study aimed to evaluate health status changes in patients with early AF, focusing on those who experience clinically significant deterioration after treatment initiation. METHODS We analyzed data from a multicenter, prospective registry of newly diagnosed patients with AF. One-year changes in health status across different treatment strategies were assessed by the Atrial Fibrillation Effect on QualiTy-of-life Overall Summary (AFEQT-OS) score. Clinically relevant deterioration and improvement in health status were defined as ≥5-point decrease and increase in AFEQT-OS score, respectively; no change was -5 to 5 points. RESULTS Overall, 1960 patients with AF were evaluated. Mean AFEQT-OS scores at baseline and 1-year follow-up were 76.7 ± 17.7 and 85.4 ± 14.8, respectively. Although most patients (53.9%) experienced clinically important improvement, a considerable proportion had no change (28.7%) or deterioration (17.4%) in their health status. Proportions of patients with no change or deterioration varied by treatment strategy: 59.9%, 53.9%, and 32.0% in rate control, antiarrhythmic drug, and catheter ablation groups, respectively. The multivariable model identified older age, female sex, heart failure, coronary artery disease, and higher baseline AFEQT-OS score as independent predictors of worsening health status, regardless of treatment strategy. CONCLUSION Many patients with early AF experience worsening or no change in health status irrespective of treatment strategy. Standardizing patients' health status assessment, especially for patients with comorbidities, may aid in patients' selection and their outcomes.

Abstract
BACKGROUND This study aimed to evaluate racial differences in bleeding incidence by conducting an ecological epidemiological study using data from Korea and the United Kingdom. METHODS We included healthy participants from the Korean National Health Insurance Service-Health Screening and the UK Biobank who underwent health examinations between 2006 and 2010 and had no comorbidities or history of medication use. Finally, 112,750 East Asians (50.7% men, mean age 52.6 years) and 210,995 Caucasians (44.7% men, mean age 55.0 years) were analyzed. The primary outcome was composed of intracranial hemorrhage (ICH) and bleeding from the gastrointestinal, respiratory, and genitourinary systems. RESULTS During the follow-up, primary outcome events occurred in 2,110 East Asians and in 6,515 Caucasians. East Asians had a 38% lower 5-year incidence rate compared with Caucasians (3.88 vs. 6.29 per 1,000 person-years; incidence rate ratio [IRR]: 0.62, 95% confidence interval [CI]: 0.59-0.65). East Asians showed a lower incidence of major bleeding (IRR: 0.86, 95% CI: 0.81-0.91), bleeding from the gastrointestinal (IRR: 0.53, 95% CI: 0.49-0.56), and genitourinary systems (IRR: 0.49, 95% CI: 0.44-0.53) compared with Caucasians. The incidence rates of ICH (IRR: 3.20, 95% CI: 2.67-3.84) and bleeding from the respiratory system (IRR: 1.28, 95% CI: 1.11-1.47) were higher in East Asians. Notably, East Asians consuming alcohol ≥3 times/week showed a higher incidence of the primary outcome than Caucasians (IRR: 1.12, 95% CI: 1.01-1.25). CONCLUSION This ecological study revealed significant racial differences in bleeding incidence, influenced by anatomical sites and lifestyle habits, underscoring the need for tailored approaches in bleeding management based on race.

Abstract
AIMS Andexanet alfa, a specific antidote to factor Xa (FXa) inhibitors, has been approved for clinical use in several countries, including Japan, based on the results from the phase 3 trial ANNEXA-4. We aimed to assess the efficacy and safety of andexanet alfa treatment in FXa inhibitor-related acute major bleeding in patients enrolled for ANNEXA-4 in Japan. METHODS This prespecified analysis included patients enrolled at Japanese sites in the prospective, open-label, single-arm ANNEXA-4 trial. Eligible patients had major bleeding within 18 hours of oral FXa inhibitor administration. The coprimary efficacy endpoints were percent change in anti-FXa activity and proportion of patients achieving excellent or good hemostatic efficacy 12 hours post-treatment. RESULTS A total of 19 patients were enrolled, all of whom had intracranial hemorrhage; 16 patients were evaluable for efficacy. Median percent reduction in anti-FXa activity from baseline to nadir was 95.4% in patients taking apixaban, 96.1% in patients taking rivaroxaban, and 82.2% in patients taking edoxaban. Overall, 14/16 patients (88%) achieved excellent or good hemostasis (apixaban, 5/5; rivaroxaban, 6/7; edoxaban, 3/4). Within 30 days, treatment-related adverse events (AEs) and serious AEs occurred in 2 and 5 patients, respectively. One patient died during follow-up, and 2 patients experienced thrombotic events. CONCLUSION Treatment with andexanet alfa rapidly reduced anti-FXa activity with favorable hemostatic efficacy in Japanese patients with acute major bleeding. Serious AEs of thrombotic events during rapid reversal of anti-FXa activity arose as particular safety concerns in this population as with previous studies.

Abstract
INTRODUCTION Limited data are available regarding the safety and effectiveness of 4-factor prothrombin complex concentrate (4F-PCC) in patients experiencing major hemorrhage or requiring expeditious surgical intervention, both globally and within Japan. METHODS We executed a prospective, observational post-marketing surveillance study of patients receiving 4F-PCC for the first time between September 19, 2017 and August 15, 2018 in Japan. Patients were subjected to a comprehensive follow-up for a duration of 4 weeks. RESULTS Of 1381 eligible patients, 1271 (92%) received a vitamin K antagonist. Among these, 58% were aged ≥ 75 years, 49% manifested atrial fibrillation, 17% presented with valvular heart disease, and 6% exhibited venous thromboembolism. The median (range) international normalized ratio was 2.67 (0.96-27.11) at baseline and 1.21 (0.45-6.61) at first measurement post-administration of 4F-PCC. The most common reason for 4F-PCC administration was intracranial hemorrhage (59.6%), followed by gastrointestinal bleeding (6.6%). Hemostatic effectiveness was achieved in 85.8% of patients. The incidences of adverse drug reactions (ADRs) and serious ADRs were 3.9% and 2.8%, respectively. Thromboembolic events (TEEs) occurred in 20 (1.5%) patients, with a mean onset of 10 days. The majority of TEEs were classified as nervous system disorders (55%). At the time of TEE, only 13% of patients resumed anticoagulant therapy. CONCLUSION The incidence of TEEs following treatment with 4F-PCC did not surpass those observed in phase 3 trials. No novel safety signals were identified. The safety and effectiveness of 4F-PCC in Japanese real-world practice were in harmony with the observations of prior studies.

Abstract
OBJECTIVES To investigate factors influencing postoperative bleeding occurrence after dental extraction in older patients receiving anticoagulation therapy. MATERIALS AND METHODS This retrospective study included patients aged ≥ 65 years receiving one of the following anticoagulants: apixaban, edoxaban, rivaroxaban, and warfarin. Patients who underwent one to multiple tooth extractions in the geriatric dentistry clinic at Tokyo Medical and Dental University Hospital between August 1, 2016, and November 30, 2020, were included. The outcome variable was postoperative bleeding occurrence. Logistic regression analysis was performed with the following ten factors as explanatory variables: age, sex, maximum systolic blood pressure during the extraction, type of local anesthesia, vertical incision, osteotomy, usage of surgical splints, the mesiodistal width of the extracted tooth on a radiograph, use of antiplatelet agents, and history of diabetes requiring medication. RESULTS Among 395 participants (mean age, 82.3 ± 6.5 years) included in this study, 75 patients experienced postoperative bleeding after tooth extraction. Logistic regression analysis revealed that the odds ratios for the vertical incision (18.400, p < 0.001), osteotomy (3.630, p = 0.00558), usage of surgical splints (1.860, p = 0.0395), and the mesiodistal width of the extracted tooth on a radiograph (1.060, p = 0.0261) were statistically significant. CONCLUSIONS For dental extraction in older patients receiving anticoagulants, postoperative bleeding is more likely to occur in patients with vertical incision, osteotomy, and posterior or multiple tooth extractions. CLINICAL RELEVANCE Dentists should consider suturing and adjunctive hemostatic procedures for patients undergoing vertical incision, osteotomy, and multiple tooth extractions while receiving anticoagulation therapy to minimize the risk of postoperative bleeding.

Clin Neurol Neurosurg 2023; 235:108042. [PMID: 37939619 DOI: 10.1016/j.clineuro.2023.108042] [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: 09/25/2023] [Revised: 10/19/2023] [Accepted: 10/31/2023] [Indexed: 11/10/2023]
Abstract
OBJECTIVES In this study, we aimed to examine the association between atrial fibrillation and mortality after ischemic stroke and evaluate the use of anticoagulation therapy for atrial fibrillation before stroke onset in patients who experienced stroke. METHODS In this retrospective observational study, we used a combined database of medical and long-term care insurance claims data from one prefecture in Japan. The data of 25,352 patients aged ≥ 65 years who were hospitalized in acute care hospitals with a diagnosis of ischemic stroke between April 2012 and March 2015 were extracted. Cox proportional hazard modeling, with adjustment for age, sex, comorbidities, and long-term care dependency level (based on the activities of daily living), was performed to evaluate the relationship between mortality and atrial fibrillation. RESULTS The prevalence of atrial fibrillation was 21.8% in the study population. A significant association was noted between mortality and atrial fibrillation (adjusted hazard ratio: 1.28, 95% confidence interval: 1.16-1.41, p < 0.001). Anticoagulant drugs were used in 32.2% of the patients with atrial fibrillation. CONCLUSIONS These results indicate that atrial fibrillation is associated with mortality after stroke; however, the use of anticoagulation therapy for atrial fibrillation is unsatisfactory. Efforts to improve the use of atrial fibrillation therapy are required in Japan.

Abstract
The benefits of direct oral anticoagulants (DOACs) and warfarin in elderly Japanese patients with non-valvular atrial fibrillation (NVAF) and high home systolic blood pressure (H-SBP) are unclear. This sub-cohort study of the ANAFIE Registry estimated the incidence of clinical outcomes in patients receiving anticoagulant therapy (warfarin and DOACs) stratified by H-SBP levels (<125 mmHg, ≥125-<135 mmHg, ≥135-<145 mmHg and ≥145 mmHg). Of the overall ANAFIE population, 4933 patients who underwent home blood pressure (H-BP) measurements were analyzed; 93% received OACs (DOACs: 3494, 70.8%; warfarin: 1092, 22.1%). In the warfarin group, at <125 mmHg and ≥145 mmHg, the respective incidence rates (per 100 person-years) were 1.91 and 5.89 for net cardiovascular outcome (a composite of stroke/systemic embolic events (SEE) and major bleeding), 1.31 and 3.39 for stroke/SEE, 0.59 and 3.91 for major bleeding, 0.59 and 3.43 for intracranial hemorrhage (ICH), and 4.01 and 6.24 for all-cause death. Corresponding incidence rates in the DOACs group were 1.64 and 2.65, 1.00 and 1.88, 0.78 and 1.69, 0.55 and 1.31, and 3.43 and 3.51. In warfarin-treated patients, the incidence rates of net cardiovascular outcome, stroke/SEE, major bleeding, and ICH were significantly increased at H-SBP ≥ 145 mmHg versus <125 mmHg. In the DOAC group, although there was no significant difference between H-SBP < 125 mmHg and ≥145 mmHg, the incidence rates of these events tended to increase at ≥145 mmHg. These results suggest that strict BP control guided by H-BP is required in elderly NVAF patients receiving anticoagulant therapy.

Abstract
BACKGROUND The prognostic effect of concomitant hypertrophic cardiomyopathy (HCM) on adverse events in patients with atrial fibrillation (AF) has not been evaluated in a multicenter prospective cohort study in Japan.Methods and Results: Using the Hokuriku-Plus AF Registry, 1,396 patients with nonvalvular AF (1,018 men, 72.3±9.7 years old) were assessed prospectively; 72 (5.2%) had concomitant HCM. During a median follow-up of 5.0 years (interquartile range 3.5-5.3 years), 79 cases of thromboembolism (1.3 per 100 person-years) and 192 of heart failure (HF) (3.2 per 100 person-years) occurred. Kaplan-Meier analysis revealed that the HCM group had a significantly greater incidence of thromboembolism (P=0.002 by log-rank test) and HF (P<0.0001 by a log-rank test) than the non-HCM group. The Cox proportional hazards model demonstrated that persistent AF (adjusted hazard ratio 2.98, 95% confidence interval 1.56-6.21), the CHA2DS2-VASc score (1.35, 1.18-1.54), and concomitant HCM (2.48, 1.16-4.79) were significantly associated with thromboembolism. Conversely, concomitant HCM (2.81, 1.72-4.43), older age (1.07, 1.05-1.10), lower body mass index (0.95, 0.91-0.99), a history of HF (2.49, 1.77-3.52), and lower left ventricular ejection fraction (0.98, 0.97-0.99) were significantly associated with the development of HF. CONCLUSIONS Concomitant HCM predicts the incidence of thromboembolism and HF in AF patients.

Abstract
BACKGROUND We previously conducted a retrospective cohort study using chart review of oral anticoagulant-naïve Japanese patients with nonvalvular atrial fibrillation (NVAF) that assessed the risk of major bleeding and stroke/systemic embolism (SE) events of apixaban versus warfarin. METHODS In this subgroup analysis, we compared the risk of major bleeding and stroke/SE events by stratifying patients into four subgroups matched 1:1 using propensity score matching (PSM) according to baseline creatinine clearance (CrCl; mL/min): ≥ 15 to < 30, ≥ 30 to < 50, ≥ 50 to < 80, and ≥ 80. RESULTS Of the 7074 patients in the apixaban group and 4998 in the warfarin group eligible for inclusion in the analysis, 4385 were included in each group after PSM. Incidence rates of major bleeding and stroke/SE events were generally lower with apixaban versus warfarin across the CrCl subgroups. When all patients with a CrCl change of < 0 mL/min per year during the study period (apixaban, n = 3871; warfarin, n = 2635) were stratified into four subgroups based on the magnitude of CrCl decline (median CrCl change [mL/min] per year: - 1.09, - 3.48, - 7.54, and - 36.92 for apixaban, and - 1.10, - 3.65, - 7.85, and - 40.40 for warfarin), the incidence rates of major bleeding and stroke/SE events generally increased with an increasing CrCl decline per year in both groups. CONCLUSIONS In Japanese patients with NVAF, the safety and effectiveness of apixaban and warfarin were consistent across different renal subgroups, including those with severe renal impairment. Our results highlight the importance of monitoring renal function variations over time in patients with NVAF. CLINICALTRIALS GOV IDENTIFIER NCT03765242.

Abstract
In this subcohort study of the ANAFIE (All Nippon Atrial Fibrillation In the Elderly) Registry enrolling >30,000 Japanese elderly (aged ≥75 years) patients with nonvalvular atrial fibrillation (NVAF), we assessed the association between patient comprehension of NVAF and adherence to anticoagulant therapy with clinical outcomes. Data from 1,968 patients evaluated for NVAF comprehension by a questionnaire consisting of 4 key questions, and 2,362 patients who completed the Morisky Medication Adherence Scale-8 questionnaire were analyzed. Overall, NVAF comprehension was low (81.9% had <3 points), and compared with high comprehension (score ≥3), low comprehension (0 points: 42.1%) was associated with poor prognosis, nonsignificantly higher risk of stroke or systemic embolic event (adjusted hazard ratio [aHR] 2.60 [95% confidence interval 0.97 to 6.94, p = 0.057]), all-cause death (aHR 1.71 [0.96 to 3.04, p = 0.069]), and significantly higher risk of net clinical outcome (composite of stroke/systemic embolic events, major bleeding, and all-cause death) (aHR 1.63 [1.04 to 2.54, p = 0.032]). Adherence to anticoagulant therapy assessed by Morisky Medication Adherence Scale-8 was high (64.9% had high adherence; 29.2%, had medium adherence), but compared with high adherence (score 8), low adherence (score <6: 5.9%) was associated with poor prognosis, significantly higher risk of ischemic stroke (aHR 2.95 [1.08 to 8.04, p = 0.035]), all-cause death (aHR 1.93 [1.16 to 3.21, p = 0.011]), and net clinical outcome (aHR 1.75 [1.12 to 2.75, p = 0.015]). Overall, NVAF comprehension and adherence showed a weak correlation to anticoagulant therapy at baseline (correlation coefficient 0.049). In conclusion, low NVAF comprehension and low anticoagulant adherence were associated with poor clinical outcomes in elderly patients with NVAF.

Mid-Term Feasibility of Percutaneous Left Atrial Appendage Occlusion in Elderly Patients with Non-Valvular Atrial Fibrillation. J Clin Med 2023; 12:6024. [PMID: 37762964 PMCID: PMC10531715 DOI: 10.3390/jcm12186024] [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: 08/23/2023] [Revised: 09/12/2023] [Accepted: 09/14/2023] [Indexed: 09/29/2023] Open
Abstract
BACKGROUND Percutaneous left atrial appendage occlusion (LAAO) therapy using the WATCHMAN system has been introduced to prevent thrombosis and minimize the use of anticoagulants in patients with non-valvular atrial fibrillation. Given the high risk of bleeding and stroke in elderly patients, these patients would be good candidates for this therapy. However, the efficacy and feasibility of LAAO therapy in elderly patients remains uncertain. METHODS Consecutive patients who underwent LAAO therapy using the WATCHMAN system in a large academic center between June 2020 and March 2023 were included. The safety and efficacy of LAAO therapy during the 1-year observation period in patients aged ≥85 years old were compared with those in the younger cohort. RESULTS A total of 188 patients (78.4 ± 6.9 years old, 133 male patients) were included. 34 patients were ≥85 years old, 96 were between 75 and 84 years old, and 58 were <75 years old. The elderly group had a higher CHA2DS2-VASc score and were at greater risk of falling-related bleeding compared with the younger cohort. The device implantations were successful in all patients except for one. During the 1-year observation period, one patient had a peri-device leak >5 mm and there were 6 device-related cases of thrombosis, whose incidence was not significantly different between the groups (p = 0.98). The cumulative incidences of bleeding and thrombotic events in the elderly group were as low as in the younger cohort (p > 0.05 for both). Most anticoagulants were terminated regardless of age. CONCLUSION The mid-term feasibility and efficacy of percutaneous LAAO therapy using the WATCHMAN system in elderly patients aged ≥85 years were as acceptable as in the younger cohort.

Abstract
In the last decade, non-vitamin K antagonist oral anticoagulants (NOACs), a new generation of OACs, were introduced to prevent thromboembolism in patients with atrial fibrillation. Although vitamin K-dependent anticoagulants have long been used as OACs, their inherent disadvantage of considerable bleeding complications has limited their use. NOACs demonstrate similar or superior clinical outcomes to those of warfarin. Although strict dose reduction criteria are recommended for NOACs, low-dose NOACs are frequently utilized, especially in Asian patients. Low-dose NOACs have shown clinical outcomes similar to those of warfarin in randomized controlled trials (RCTs) and real-world studies. However, off-label low-dose NOACs have shown inconsistent results compared with standard-dose NOACs and warfarin. Therefore, strict dose reduction criteria for NOACs should be followed until RCTs confirm the issues associated with NOAC underdosing.

Abstract
BACKGROUND This ANAFIE Registry sub-analysis investigated 2-year outcomes and oral anticoagulant (OAC) use stratified by glycated hemoglobin (HbA1c) levels among Japanese patients aged ≥ 75 years with non-valvular atrial fibrillation (NVAF) with and without clinical diagnosis of diabetes mellitus (DM). METHODS The ANAFIE Registry was a large-scale multicenter, observational study conducted in Japan; this sub-analysis included patients with baseline HbA1c data at baseline. The main endpoints evaluated (stroke/systemic embolic events [SEE], major bleeding, intracranial hemorrhage, cardiovascular death, all-cause death, and net clinical outcome [a composite of stroke/SEE, major bleeding, and all-cause death]) were stratified by HbA1c levels (< 6.0%; 6.0% to < 7.0%; 7.0% to < 8.0%; and ≥ 8.0%). RESULTS Of 17,526 patients with baseline HbA1c values, 8725 (49.8%) patients had HbA1c < 6.0%, 6700 (38.2%) had 6.0% to < 7.0%, 1548 (8.8%) had 7.0% to < 8.0%, and 553 (3.2%) had ≥ 8.0%. Compared with other subgroups, patients with HbA1c ≥ 8.0% were more likely to have lower renal function, higher CHA2DS2-VASc and HAS-BLED scores, higher prevalence of non-paroxysmal AF, and lower direct OAC (DOAC) administration, but higher warfarin administration. The HbA1c ≥ 8.0% subgroup had higher event rates for all-cause death (log-rank P = 0.003) and net clinical outcome (log-rank P = 0.007). Similar trends were observed for stroke/SEE. In multivariate analysis, risk of all-cause death (adjusted hazard ratio [aHR]: 1.46 [95% confidence interval 1.11-1.93]) and net clinical outcome (aHR 1.33 [1.05-1.68]) were significantly higher in the HbA1c ≥ 8.0% subgroup. No significant differences were observed in risks of major bleeding or other outcomes in this and other subgroups. No interaction was observed between HbA1c and OACs. Use/non-use of antidiabetic drugs was not associated with risk reduction; event risks did not differ with/without injectable antidiabetic drugs. CONCLUSIONS Among elderly Japanese patients with NVAF, only HbA1c ≥ 8.0% was associated with increased all-cause death and net clinical outcome risks; risks of the events did not increase in other HbA1c subgroups. Relative event risks between patients treated with DOACs and warfarin were not modified by HbA1c level. TRIAL REGISTRATION UMIN000024006; date of registration: September 12, 2016.

Abstract
A direct relationship between serum uric acid levels and hypertension, cardiovascular, renal and metabolic diseases has been reported in many basic and epidemiological studies. Among these, high blood pression is one of the most common features associated with hyperuricemia. In this regard, several small-scale interventional studies have demonstrated a significant reduction in blood pressure in hypertensive or prehypertensive patients on uric acid-lowering drugs. These observation or intervention studies have led to affirm that there is a causal relationship between uric acid and hypertension. While the clinical association between uric acid and high blood pressure is notable, no clear conclusion has yet been reached as to whether lowering uric acid is beneficial to prevent cardiovascular and renal metabolic diseases. Recently, several prospective randomized controlled intervention trials using allopurinol and other uric acid-lowering drugs have been reported, and the results from these trials were almost negative, suggesting that the correlation between hyperuricemia and cardiovascular disease has no causality. However, it is important to note that in some of these recent studies there were high dropout rates and an important fraction of participants were not hyperuricemic. Therefore, we should carry caution in interpreting the results of these studies. This review article presents the results of recent clinical trials using uric acid-lowering drugs, focusing on hypertension and cardiovascular and renal metabolic diseases, and discusses the future of uric acid therapy.

Mizusugi M, Kenzaka T. Asymptomatic Idiopathic Renal Infarction Detected Incidentally on Contrast-Enhanced Computed Tomography: A Case Report. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1176. [PMID: 37374380 DOI: 10.3390/medicina59061176] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/19/2023] [Revised: 06/13/2023] [Accepted: 06/17/2023] [Indexed: 06/29/2023]
Abstract
Background: Renal infarction is an extremely rare disease. Although more than 95% of cases are symptomatic, there have been no previously reported asymptomatic cases, without any abnormal blood and urine test findings. Furthermore, the efficacy of long-term treatment of idiopathic renal infarction remains unknown. Case Presentation: A 63-year-old Japanese male underwent laparoscopy; a very low anterior resection of the rectum for lower rectal cancer (stage II) four years and five months prior to diagnosis with renal infarction. During the follow-up imaging studies, asymptomatic idiopathic renal infarction was found incidentally. The blood and urine test findings were normal. Contrast-enhanced computed tomography revealed a linearly bordered area of poor contrast in the dorsal region of the right kidney; however, no renal artery lesions, thromboembolic disease, or coagulation abnormalities were observed. Initial treatment with rivaroxaban 15 mg/day resulted in the remission of the infarcted lesion. The anticoagulation therapy was terminated after about 18 months without any incidences of re-infarction or bleeding events. Conclusions: We reported a very rare case of asymptomatic idiopathic renal infarction where blood and urine tests revealed no abnormal findings, and it was diagnosed incidentally during a post-treatment follow-up examination for lower rectal cancer. Long-term anticoagulant therapy for idiopathic renal infarction should be terminated at an appropriate time, taking the risk of bleeding into account.

Renal Function and Clinical Outcomes Among Elderly Patients With Nonvalvular Atrial Fibrillation From ANAFIE. JACC. ASIA 2023; 3:475-487. [PMID: 37396416 PMCID: PMC10308099 DOI: 10.1016/j.jacasi.2023.02.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 03/14/2022] [Revised: 01/24/2023] [Accepted: 01/30/2023] [Indexed: 07/04/2023]
Abstract
Background Advancing age, decreasing renal function, and atrial fibrillation are strongly associated. Real-world evidence of direct oral anticoagulant (DOAC) use among elderly patients ≥75 years of age with nonvalvular atrial fibrillation and renal dysfunction is limited. Objectives This study sought to assess 2-year outcomes and anticoagulant treatment, stratified by renal function. Methods Enrolled patients were divided into 4 subgroups by creatinine clearance (CrCl) to determine the impact of renal dysfunction on clinical outcomes. Results Of 32,275 patients, 26,202 with CrCl data were analyzed (median follow-up 2.00 [IQR: 1.92-2.00] years); 1.3% of patients had CrCl <15 mL/min, 10.7% had CrCl 15 to <30 mL/min, 33.4% had CrCl 30 to <50 mL/min, 35.8% had CrCl ≥50 mL/min, and 18.9% had unknown CrCl. Cumulative incidences of stroke/systemic embolic events, major bleeding, major plus clinically relevant nonmajor bleeding, cardiovascular death, all-cause death, and net clinical outcomes increased with decreasing CrCl. In multivariable Cox regression analysis, lower CrCl emerged as an independent risk factor for these clinical outcomes, except for major bleeding, compared with CrCl ≥50 mL/min. The effectiveness and safety of DOACs over warfarin were similar or better across 3 CrCl subgroups with CrCl 15 mL/min or more. DOAC use was associated with a lower risk of stroke/systemic embolic events, major bleeding, cardiovascular death, all-cause death, and net clinical outcome compared with warfarin in patients with CrCl 30 to <50 mL/min. Conclusions Incidences of major clinical outcomes increased with decreasing renal function in elderly nonvalvular atrial fibrillation patients. DOACs were effective and safe even in patients with renal dysfunction (CrCl 15-<50 mL/min).

Abstract
Although many causative genes for primary cardiomyopathy have been identified, the use of genetic testing in routine practice is limited in Japan presently. Genetic diagnosis has been reported to be useful for early diagnosis through cascade genetic screening in the family, differentiating secondary cardiomyopathies, and predicting prognosis in some patients; nonetheless, the acquisition of genetic information for cardiomyopathy is stagnating in actual clinical practice. There seem to be a number of reasons for this phenomenon, and although the use of next-generation sequencers has resolved some of the past issues, the importance of pathogenicity studies of variants that are identified is growing. To ensure that patients with cardiomyopathy and their relatives can receive precision medicine, the results of genetic analysis linked to clinical information need to be collected, and a database of variants in Japanese people needs to be established.

Abstract
Background: Off-label dosing of direct oral anticoagulants (DOAC) as a treatment for non-valvular atrial fibrillation (NVAF) is problematic. Here, we investigated the status of rivaroxaban and edoxaban dosing by monitoring plasma concentrations (PCs). Methods and Results: We monitored drug PCs in 391 and 333 outpatients receiving rivaroxaban and edoxaban, respectively, for NVAF. Drug doses were adjusted if the PC was above the cut-off value (rivaroxaban: 404 ng/mL; edoxaban: 402 ng/mL), determined from receiver operating characteristic curves for predicting bleeding events. On-label standard dosing was reduced to off-label underdosing due to high PCs above the cut-off more often for rivaroxaban (28.1%) than edoxaban (12.6%; P<0.001). Over a median follow-up of 13 months for rivaroxaban and 10 months for edoxaban, the annual incidence of bleeding events was higher with rivaroxaban than with edoxaban (4.88 vs. 3.73 patient-years; P<0.05), although no thromboembolic events occurred in either group. Furthermore, for patients with creatinine clearance >50 mL/min and body weight ≤60 kg, there was a greater incidence of bleeding events with rivaroxaban on-label 15 mg dosing than with edoxaban on-label 30 mg dosing (22.2% vs 2.9%; P<0.01). Conclusions: Monitoring the PCs of rivaroxaban and edoxaban in NVAF patients enables dose adjustments to reduce bleeding risk. The incidence of bleeding under drug PC monitoring was less in the edoxaban than rivaroxaban group.

Abstract
Anticoagulation with warfarin in Asian patients with atrial fibrillation (AF) often has been decreased as an international normalized ratio (INR) of prothrombin time 1.6-2.6 due to fear of bleeding, although universal criteria recommend an INR of 2.0-3.0. In this randomized, open-label trial, low-intensity anticoagulation (INR 1.6-2.6) was compared with standard-intensity anticoagulation (INR 2.0-3.0) with warfarin. A total 616 patients with AF and at least 1 risk factor for stroke were randomized to low-intensity anticoagulation (n = 308) and standard-intensity anticoagulation (n = 308) groups. The intention-to-treat analysis was performed to determine differences. The baseline characteristics of the two groups were comparable. New-onset stroke occurred in 2 patients (0.44% per year) in the low-intensity group and 5 patients (1.05% per year) in the standard-intensity group (HR 0.42, 95% CI 0.08-2.15). Major bleeding occurred in 4 patients (0.89% per year) in the low-intensity group and 5 patients (1.06% per year) in the standard-intensity group (HR 0.84, 95% CI 0.22-3.11). The rate of the net clinical outcome (composite of stroke, systemic embolism, major bleeding, and death) was 1.33% per year in the low-intensity group compared with 2.12% per year in the standard-intensity group (HR 0.63, 95% CI 0.23-1.72). In Asian patients with AF, clinical outcomes were not different between low-intensity and standard-intensity anticoagulation with warfarin.

Abstract
We provided general anesthesia management to a patient with advanced atrioventricular block, which was discovered in the remote period after open-heart surgery. A 21-year-old man with Noonan syndrome was scheduled to undergo excision of a median intramandibular tumor. At 2 months of age, the patient underwent endocardial repair for congenital heart disease. During our preoperative examination, an atrioventricular block was detected, which had not been previously noted. Emergency drugs were administered, and a transcutaneous pacemaker was placed. During anesthesia induction, mask ventilation was easy, and intubation was performed smoothly using a video laryngoscope. The transcutaneous pacemaker was activated in demand mode at a pacing rate of 50 cycles/min approximately throughout the anesthesia time, and the hemodynamic status remained stable. The effect of intraoperatively administered atropine was brief, lasting only a few seconds. Although body movements due to thoracoabdominal muscle spasm were observed during pacemaker activation, they did not interfere with surgery. In postoperative patients with congenital heart disease, an atrioventricular block may be identified in the remote period, and preoperative evaluation should be based on this possibility. In addition, during anesthesia management, it is important to prepare multiple measures to maintain hemodynamic status.

Abstract
BACKGROUND The incidence and prevalence of atrial fibrillation (AF) are increasing. The white blood cell (WBC) count is an indicator of systemic inflammation and is related to increased cardiovascular disease risk. Using data from the Suita Study, we investigated the association between WBC count and AF risk in the general Japanese population.Methods and Results: This prospective cohort study included 6,884 people, aged 30-84 years, with no baseline AF. Cox regression was used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) for AF incidence by WBC count quintile. Within a median follow-up period of 14.6 years, 312 AF cases were diagnosed. Compared with the lowest WBC count quintile, the highest quintile was associated with an increased AF risk (HR 1.57; 95% CI 1.07-2.29). The association was more pronounced among women than men (HR 2.16 [95% CI 1.10-4.26] and 1.55 [95% CI 0.99-2.44], respectively; P interaction=0.07), and among current than non-smokers (HR 4.66 [95% CI 1.89-11.50] and 1.61 [95% CI 1.01-2.57], respectively; P interaction=0.20). For each 1.0×109-cells/L increment in WBC count, AF risk increased by 9% in men (9% in non-smokers, 10% in current smokers) and 20% in women (13% in non-smokers, 32% in current smokers). CONCLUSIONS A higher WBC count was positively associated with an elevated AF risk in the general Japanese population, especially in women who smoked.

Abstract
In the countries like Japan where anticoagulation is not recommended in hemodialysis patients, the feasibility of percutaneous left atrial appendage closure (LAAC) in hemodialysis patients with non-valvular atrial fibrillation (NVAF) accompanying high risks of thromboembolic stroke and bleeding remains unknown. Peri-procedural and 45-day clinical outcomes following LAAC using WATCHMAN system, which were performed in our institute between Jun 2020 and April 2022 according to the Japanese Circulation Society guidelines, were retrospectively compared between those with and without hemodialysis. 118 patients (median 79 years, 81 men) consisting of 25 hemodialysis patients and 93 non-hemodialysis patients were included. CHADS score was 3 (2, 4) in the hemodialysis patients and 3 (2, 4) in the non-hemodialysis patients (p = 0.98). HAS-BREAD score was 4 (3, 5) in the hemodialysis patients and 3 (2, 3) in the non-hemodialysis patients (p < 0.001). All procedures were successful, except for a non-hemodialysis patient with a larger left atrial appendage. There were no major complications during index hospitalization and 45-day observational period, except for a hemodialysis patient with suspected bleeding and a non-hemodialysis patient who died due to cardiac amyloidosis. LAAC seems to be feasible in hemodialysis patients with high risks of thromboembolic events and bleedings.

Abstract
BACKGROUND The prospective Control of HEART rate in inFant and child tachyarrhythmia with reduced cardiac function Using Landiolol (HEARTFUL) study investigated the effectiveness and safety of landiolol, a short-acting β1 selective blocker, in children.Methods and Results: Twenty-five inpatients aged ≥3 months to <15 years who developed supraventricular tachyarrhythmias (atrial fibrillation, atrial flutter, supraventricular tachycardia, and inappropriate sinus tachycardia) were treated with landiolol. The primary endpoint, the percent of patients with a reduction in heart rate ≥20% from the initial rate of tachycardia, or termination of tachycardia at 2 h after starting landiolol, was achieved in 12/25 patients (48.0%; 95% CI 28.4-67.6), which exceeded the predetermined threshold (38.0%). At 2 h after starting landiolol administration, heart rate had decreased by ≥20% in 45.8% (11/24) and recovery to sinus rhythm was achieved in 40.0% (6/15) of the patients. Adverse reactions (ARs) occurred in 24.0% (6/25) of patients, and the study was discontinued in 4.0% (1/25) of the patients; however, none of these ARs were considered serious. The most common AR was hypotension (20.0% [5/25] of patients). CONCLUSIONS The HEARTFUL study has demonstrated the efficacy of landiolol, by reducing heart rate or terminating tachycardia, in pediatric patients with supraventricular tachyarrhythmias. Although serious ARs and concerns were not identified in this study, physicians should be always cautious of circulatory collapse due to hypotension.

Prognostic impact of heart rate during atrial fibrillation on clinical outcomes in elderly non-valvular atrial fibrillation patients: ANAFIE Registry sub-cohort study. J Cardiol 2022; 81:441-449. [PMID: 36427691 DOI: 10.1016/j.jjcc.2022.11.011] [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: 06/24/2022] [Revised: 10/18/2022] [Accepted: 11/07/2022] [Indexed: 11/23/2022]
Abstract
BACKGROUND Elderly patients with atrial fibrillation (AF) are at a higher risk for all-cause mortality and heart failure. Rate control is an essential component in AF management. This exploratory study assessed the relationship between resting heart rate during AF at baseline and clinical outcomes in Japanese elderly non-valvular AF (NVAF) patients, using the All Nippon AF In the Elderly Registry (ANAFIE) dataset. METHODS This sub-cohort included patients who agreed to participate and presented with AF at enrollment in the ANAFIE study. They were categorized into six groups according to the resting heart rate during AF. Outcomes included 2-year cumulative incidences of stroke/systemic embolic events (SEE), ischemic stroke, major bleeding, cardiovascular (CV) events, CV death, all-cause death, and net clinical outcome, a composite of stroke/SEE, major bleeding, and all-cause death. RESULTS Of the 8292 patients included in this sub-cohort (paroxysmal, 1496; non-paroxysmal, 6796), 90 % of patients were using anticoagulants. Higher heart rate was more frequently reported in women and in patients with paroxysmal AF and was associated with increased use of direct oral anticoagulants (DOACs) and antiarrhythmic drugs. Heart rate ≥110 beats per minute (bpm) was associated with a significantly higher incidence of cardiac events and numerically higher incidences of CV death and all-cause death compared with a heart rate of 60 to <80 bpm, all of which were driven by an increased risk in patients with non-paroxysmal AF. Hazard ratios by the type of anticoagulant for each clinical outcome were comparable across all heart rate categories, indicating no significant interactions. CONCLUSIONS Elderly Japanese patients with non-paroxysmal NVAF and a heart rate ≥110 bpm have an increased risk of cardiac events. There was no interaction between heart rate category and the relative risk of adverse clinical events in patients taking DOACs compared with those taking warfarin.

Abstract
Atrial fibrillation (AF) is the most common arrhythmia encountered in clinical practice and its prevalence increases with age. AF causes palpitations, heart failure, and cardiogenic embolism. Of them, the most critical and fatal complication is a cardio-embolic event. Oral anticoagulation plays a central role in reducing stroke risk in AF patients. Recently, when oral anticoagulation is considered in patients with non-valvular AF who are eligible for direct oral coagulations, they are preferred to vitamin K antagonist based on accumulating evidence. Although many patients can tolerate oral anticoagulation, there is a subset of patients who cannot tolerate long-term oral anticoagulation. Such a subset has a higher bleeding risk as indicated by the HAS-BLED score under oral anticoagulation. This subset of patients requires effective and safe non-pharmacological alternative therapies for stroke prevention. One of the promising non-pharmacological therapies is left atrial appendage closure. Three randomized controlled trials demonstrated non-inferiority of percutaneous left atrial appendage closure using WATCHMAN family to oral anticoagulation (Boston Scientific, Marlborough, MA, USA). WATCHMAN FLX, which was innovated following WATCHMAN 2.5, was associated with fewer safety events and a higher success rate of effective appendage closure. Nevertheless, several unsolved issues remain, including device-related thrombosis, post-treatment antithrombotic therapy, and peri-device leakage. Left atrial appendage closure for patients with non-valvular AF may be an alternative therapy to avoid cardiac embolism for high bleeding risk patients with contraindications to long-term oral anticoagulation therapy.

Abstract
BACKGROUND Drugs with new mechanisms of action are continually being developed, but it is difficult to capture whether a drug induces QT prolongation/torsade de pointes (TdP) in preclinical and preapproval clinical trials. OBJECTIVE To evaluate drugs associated with drug-induced QT prolongation/TdP using a real-world database in Japan. PATIENTS AND METHODS A search was performed in the Japanese Adverse Drug Event Report (JADER) database for QT prolongation and TdP. The reporting odds ratio (ROR) was calculated to identify potential drug-induced QT prolongation/TdP association. RESULTS Among the reported 4,326,484 data entries, 3410 patients exhibited QT prolongation/TdP (2707 with QT prolongation, 703 with TdP) with the suspected drugs. Of these patients, 53.9% were females. The highest occurrence was in the 70- to 79-year-old age group (24.7%). The most common types of drugs involved were cardiovascular drugs, central nervous system (CNS) drugs, anticancer drugs, and anti-infective drugs; the rate of overdose was reportedly very low at 1.6%. The highest adjusted RORs were observed for nifekalant (351.41, 95% confidence interval (CI) 235.85-523.59), followed by vandetanib (182.55, 95% CI 108.11-308.24), evocalcet (181.59, 95% CI 132.96-248.01), bepridil (160.37, 95% CI 138.17-186.13), diarsenic trioxide (79.43, 95% CI 63.98-98.62), and guanfacine (78.29, 95% CI 58.51-104.74). Among the drugs launched in Japan during the last decade, vandetanib had the highest adjusted RORs. CONCLUSIONS This study using the JADER database showed that antiarrhythmic drugs, calcium-sensing receptor agonists, small-molecule targeted anticancer drugs, and CNS drugs are associated with QT prolongation/TdP. Further pharmacoepidemiological studies, such as cohort studies using large databases, are needed to prove these causal relationships.

Stroke Risk Stratification With the CHADS 2 Score in Patients Without Atrial Fibrillation Who Underwent Percutaneous Coronary Intervention. Am J Cardiol 2022; 181:9-17. [PMID: 35973833 DOI: 10.1016/j.amjcard.2022.06.057] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/31/2022] [Revised: 06/20/2022] [Accepted: 06/28/2022] [Indexed: 11/22/2022]
Abstract
The clinical significance of the CHADS2 score remains unclear in patients with coronary artery disease (CAD) without atrial fibrillation (AF). Therefore, the purpose of this study was to evaluate the association between the CHADS2 score and the long-term risk of ischemic stroke and its severity in patients with CAD with and without AF. Using the CREDO (Coronary Revascularization Demonstrating Outcome study)-Kyoto Registry Cohort-3, the present study population consisted of 11,516 patients with CAD who underwent percutaneous coronary intervention without oral anticoagulants at discharge. We divided the patients into 2 groups according to the presence (n = 721) or absence (n = 10,795) of AF. As the CHADS2 score increased from 0 or 1 to 6, the cumulative 5-year incidence of ischemic stroke incrementally increased from 2.1% to 17.1% in patients without AF and from 4.2% to 40.7% in patients with AF. The cumulative 5-year incidence of ischemic stroke in patients without AF and a CHADS2 score of 2 were numerically comparable to that in patients with AF and a CHADS2 score of 1 (3.4% and 3.7%). In the 423 patients who developed ischemic stroke, the modified Rankin Scale score was not significantly different between patients with and without AF (p for trend = 0.12). In patients with and without AF, the increase in the CHADS2 score was significantly associated with the greater prevalence of higher modified Rankin Scale scores (p for trend = 0.03 and <0.001, respectively). An increasing CHADS2 score was associated with an incrementally increased risk for ischemic stroke and greater severity of ischemic stroke in patients with and without AF.

Abstract
Brugada syndrome (BrS) is one of the main inherited arrhythmia syndromes causing ventricular fibrillation (VF) and sudden cardiac death in young to middle-aged men, especially in Asians. The diagnosis of BrS is based on spontaneous or drug-provoked type 1 Brugada electrocardiogram. The current reliable therapy for BrS patients with VF history is the implantation of an implantable cardioverter-defibrillator. As for BrS patients without VF history, how asymptomatic BrS patients should effectively be treated is still uncertain because risk stratification of the BrS is still inadequate. Various parameters and combinations of several parameters have been reported for risk stratification of BrS. The SCN5A gene is believed to be the only gene that is responsible for BrS, and it has been reported to be useful for risk stratification. This review focuses on risk stratification of BrS patients, and focuses specifically on BrS patients of Asian descent.

Abstract
BACKGROUND The existence of epicardial connection(s) (ECs) between the pulmonary veins (PVs) and atrium may hinder establishing a complete PV antrum isolation (AI) (PVAI) in patients with atrial fibrillation (AF). Thus, the purpose of this study was to determine the prevalence and location of ECs inside the conventional PVAI lines.Methods and Results: Three-hundred consecutive patients with non-valvular AF were evaluated. This study revealed that: (1) the prevalence of patients with ECs and the number of ECs per patient between the PVs and atrium became significantly greater, respectively, in accordance with the progression of paroxysmal to long-lasting AF and left atrial enlargement; (2) some ECs were located at sites far distal to the PVAI lines; (3) 25% of ECs could be detected only by high-density mapping catheters, but not by conventional circular mapping catheters; (4) a B-type natriuretic peptide (BNP) level of 176.6pg/mL and left atrial volume (LAV) of 129.0 mL may be important predictors of the presence of ECs; and (5) the rate of conduction of ECs from the right PVs was dominantly to the atrium and His-bundle, and that from the left PVs to the coronary sinus was most dominant. CONCLUSIONS The PVAI may not be completed by using only a conventional PVAI method, and additional EC ablation inside the PVAI lines detected using high-density mapping may be able to achieve a more complete PVAI.

Abstract
Background: Percutaneous left atrial appendage closure using the WATCHMAN system, to prevent thrombosis and minimize anti-coagulant use in patients with non-valvular atrial fibrillation, has recently been introduced. The safety and efficacy of new-generation WATCHMAN FLX, as compared to conventional WATCHMAN 2.5, remain unknown. Methods: Consecutive patients who received percutaneous left atrial appendage closure using the WATCHMAN system in our institute, between June 2020 and December 2021, were retrospectively analyzed. Safety and efficacy during the 45-day observational period were compared between the two devices. Results: A total of 93 patients (73.0 ± 7.3 years old, 63 men) who received WATCHMAN FLX (n = 44) or WATCHMAN 2.5 (n = 49) were included. The device implant success rate was 100% in the FLX device group and 98% in the 2.5 device group. There were no procedure-related complications in the FLX group, and one non-relevant pericardial effusion in the 2.5 device group. During the 45-day observational period, there were no procedure-related adverse events. No patients in the FLX group had a peri-device leak >3 mm, whereas two patients in the 2.5 device group had a peri-device leak >3 mm. Anti-coagulants could be terminated in most of the patients (85% versus 88%; p = 0.68). Conclusions: Percutaneous left atrial appendage closure using new-generation WATCHMAN FLX seemed to be as safe and effective as conventional WATCHMAN 2.5 during the short-term observational period.
