Background: Off-label dosing of direct oral anticoagulants (DOACs) is encountered clinically among patients with atrial fibrillation (AF), although data on the clinical outcomes of over- and under-dosing are lacking in Japan. Methods and Results: We examined the clinical outcomes of off-label DOAC dosing using the SAKURA AF Registry, a prospective multicenter registry in Japan. Among 3,237 enrollees, 1,676 under any of the 4 DOAC regimens were followed up for a median of 39.3 months: 746 (45.0%), appropriate standard-dose; 477 (28.7%), appropriate low-dose; 66 (4.0%), over-dose; and 369 (22.2%) under-dose. Compared with the standard-dose group, patients in the under- and over-dose groups were significantly older and had a higher stroke risk. After multivariate adjustment, stroke/systemic embolism (SE) and death events were equivalent between the standard- and under-dose groups, but major bleeding events tended to be lower in the under-dose group (hazard ratio [HR] 0.474, P=0.0739). Composite events (stroke/SE, major bleeding, or death) were higher in the over-dose than in the standard-dose group (HR 2.714, P=0.0081). Conclusions: Clinical outcomes were not worse for under-dose than for standard-dose users among patients with different backgrounds. Over-dose users, however, were at higher risk for all clinical events and required careful follow-up. Further studies are needed to clarify the safety and effectiveness of off-label DOAC dosing in Japan.

Background:The hypothesis of this study is that latent class analysis could identify the subphenotypes of out-of-hospital cardiac arrest (OHCA) patients associated with the outcomes and allow us to explore heterogeneity in the effects of extracorporeal cardiopulmonary resuscitation (ECPR).Methods and Results:This study was a retrospective analysis of a multicenter prospective observational study (CRITICAL study) of OHCA patients. It included adult OHCA patients with initial shockable rhythm. Patients from 2012 to 2016 (development dataset) were included in the latent class analysis, and those from 2017 (validation dataset) were included for evaluation. The association between subphenotypes and outcomes was investigated. Further, the heterogeneity of the association between ECPR implementation and outcomes was explored. In the study results, a total of 920 patients were included for latent class analysis. Three subphenotypes (Groups 1, 2, and 3) were identified, mainly characterized by the distribution of partial pressure of O2(PO2), partial pressure of CO2(PCO2) value of blood gas assessment, cardiac rhythm on hospital arrival, and estimated glomerular filtration rate. The 30-day survival outcomes were varied across the groups: 15.7% in Group 1; 30.7% in Group 2; and 85.9% in Group 3. Further, the association between ECPR and 30-day survival outcomes by subphenotype groups in the development dataset was as varied. These results were validated using the validation dataset.Conclusions:The latent class analysis identified 3 subphenotypes with different survival outcomes and potential heterogeneity in the effects of ECPR.

Background:There are concerns that Asian patients respond differently to some medications. This study evaluated the efficacy and safety of evolocumab among Asian vs. other subjects in the FOURIER trial, which randomized stable atherosclerosis patients to receive either evolocumab or placebo.Methods and Results:Effects of adding evolocumab vs. placebo to background statin therapy on low-density lipoprotein cholesterol (LDL-C) reductions, cardiovascular outcomes, and adverse events were compared among 27,564 participants with atherosclerotic disease, according to self-reported Asian (n=2,723) vs. other (n=24,841) races followed for a median of 2.2 years in the FOURIER trial. The primary endpoint was a composite of cardiovascular death, myocardial infarction, stroke, hospitalization for unstable angina, or coronary revascularization. At randomization, Asians had slightly lower LDL-C (median 89 [IQR 78–104] mg/dL vs. 92 [80–109] mg/dL; P<0.001) and were much less likely to be on a high-intensity statin (33.3% vs. 73.3%; P<0.001). Evolocumab lowered LDL-C more in Asians than in others (66% vs. 58%; P<0.001). The effect of evolocumab on the primary endpoint was similar in Asians (HR, 0.79; 95% CI, 0.61–1.03) and others (HR, 0.86; 95% CI, 0.79–0.93; P interaction=0.55). There was no excess of serious adverse events with evolocumab among Asians over others.Conclusions:Use of evolocumab robustly lowers LDL-C and is equally efficacious in lowering the risk of cardiovascular events and safe in Asians as it is in others.

Background: The Impella®percutaneous left ventricular assist device has been available in Japan since 2017. This is the first large-scale registry study to analyze the efficacy and safety of Impella in Japanese patients with acute myocardial infarction with cardiogenic shock (AMICS).Methods and Results: The Japanese registry for Percutaneous Ventricular Assist Device (J-PVAD) has registered all consecutive Japanese patients treated with Impella. We extracted data for 593 AMICS patients from J-PVAD and analyzed 30-day survival and safety profiles. Overall 30-day survival was 63.1%. The 30-day survival of the Impella alone and Impella plus venoarterial extracorporeal membrane oxygenation (ECPELLA) groups was 80.9% and 45.7%, respectively. The Impella alone group was older and had a lower rate of cardiac arrest, milder consciousness disturbance, less inotrope use, lower serum lactate concentrations, higher B-type natriuretic peptide concentrations, and higher left ventricular ejection fraction (LVEF) than the ECPELLA group. Cox regression analysis revealed that older age and comorbid renal disturbance were common risk factors affecting 30-day mortality in both groups. Major adverse events were hemolysis (10.8%), hemorrhage/hematoma (7.6%), peripheral ischemia (4.4%), stroke (1.3%), and thrombosis (0.7%). LVEF improved in both groups during support.Conclusions: AMICS treatment with Impella showed favorable 30-day survival and safety profiles. The survival rate of patients treated with Impella alone was particularly high. Further studies are needed to improve outcomes of patients with ECPELLA support.

Background: This sub-analysis of the ANAFIE Registry, a prospective, observational study of >30,000 Japanese non-valvular atrial fibrillation (NVAF) patients aged ≥75 years, assessed the prevalence of direct oral anticoagulant (DOAC) under-dose prevalence, identified the factors of under-dose prescriptions, and examined the relationship between DOAC dose and clinical outcomes.Methods and Results: Patients, divided into 5 groups by DOAC dose (standard, over-, reduced, under-, and off-label), were analyzed for background factors, cumulative incidences, and clinical outcome risk. Endpoints were stroke/systemic embolic events (SEE), major bleeding, and all-cause death during the 2-year follow-up. Of 18,497 patients taking DOACs, 20.7%, 3.8%, 51.6%, 19.6%, and 4.3%, were prescribed standard, over-, reduced, under-, and off-label doses. Factors associated with under-dose use were female sex, age ≥85 years, reduced creatinine clearance, history of major bleeding, polypharmacy, antiplatelet agents, heart failure, dementia, and no history of catheter ablation or cerebrovascular disease. After confounder adjustment, under-dose vs. standard dose was not associated with the incidence of stroke/SEE or major bleeding but was associated with a higher mortality rate. Patients receiving an off-label dose showed similar tendencies to those receiving an under-dose; that is, they showed the highest mortality rates for stroke/SEE, major bleeding, and all-cause death.Conclusions: Inappropriate low DOAC doses (under- or off-label dose) were not associated with stroke/SEE or major bleeding but were associated with all-cause death.

Background:The aim of our study was to investigate in detail the temporal trends in in-hospital characteristics, actual management, and survival, including neurological status, among adult out-of-hospital cardiac arrest (OHCA) patients in recent years.Methods and Results:From the prospective database of the Comprehensive Registry of Intensive Care for OHCA Survival (CRITICAL) study in Osaka, Japan, we enrolled all OHCA patients aged ≥18 years for whom resuscitation was attempted, and who were transported to participating hospitals between the years 2013 and 2017. The primary outcome measure was 1-month survival with favorable neurological outcome after OHCA. Temporal trends in in-hospital management and favorable neurological outcome among adult OHCA patients were assessed. Of the 11,924 patients in the database, we included a total of 10,228 adult patients from 16 hospitals. As for in-hospital advanced treatments, extracorporeal cardiopulmonary resuscitation (ECPR) use increased from 2.4% in 2013 to 4.3% in 2017 (P for trend <0.001). However, the proportion of adult OHCA patients with favorable neurological outcome did not change during the study period (from 5.7% in 2013 to 4.4% in 2017, adjusted odds ratio (OR) for 1-year increment: 0.98 (95% confidence interval: 0.94–1.23)).Conclusions:In this target population, in-hospital management such as ECPR increased slightly between 2013 and 2017, but 1-month survival with favorable neurological outcome after adult OHCA did not improve significantly.

Background: A prospective, 3-year comparative observational study compared the risk of cardiovascular events in patients with osteoarthritis or rheumatoid arthritis prescribed celecoxib or a nonsteroidal antiinflammatory drug (NSAID). Methods and Results: Patients prescribed celecoxib (n=5,470) or NSAIDs (n=5,059) between November 1, 2007, and July 31, 2008 in 1,084 hospitals and clinics in Japan were eligible for safety analysis. Mean (standard deviation) observation for the celecoxib group was 716 (420) days and 692 (426) days for the NSAID group (P=0.004). Composite I (adjudicated cardiovascular adverse events of myocardial infarction, angina pectoris, heart failure, cerebral infarction, cerebral hemorrhage) number of events (percentage) and rate/1,000 person years was 66 (1.2%) and 6.2 (10,745 person years), respectively, for the celecoxib and 65 (1.3%) and 6.8 (9,601 person years) for the NSAID (P=0.58) groups. Composite II (all cardiovascular events) number of events (percentage) and rate/1,000 person years was 79 (1.4%) and 7.4, respectively, for the celecoxib and 84 (1.7%) and 8.8 for the NSAID (P=0.26) group. Adjusted Cox hazards ratio (95% confidence interval) was 0.89 (0.63–1.27; P=0.52) for Composite I, 0.87 (0.63–1.19; P=0.39) for Composite II and 1.03 (0.75–1.41; P=0.87) for death from all causes. Conclusions: After adjustment for confounding variables, celecoxib was not associated with an increase of cardiovascular risk in comparison with nonselective NSAID in Japanese patients with rheumatoid arthritis or osteoarthritis in an observational setting.

Background: A large-scale prospective study of the efficacy and safety of warfarin for the treatment of venous thromboembolism (VTE) has not been conducted in Japan. Therefore, we conducted a real-world prospective multicenter observational cohort study (AKAFUJI Study; UMIN000014132) to investigate the efficacy and safety of warfarin for VTE.Methods and Results: Between May 2014 and March 2017, 352 patients (mean [±SD] age 67.7±14.8 years; 57% female) with acute symptomatic/asymptomatic VTE were enrolled; 284 were treated with warfarin. The cumulative incidence of recurrent symptomatic VTE was higher in patients without warfarin than in those treated with warfarin (8.7 vs. 2.2 per 100 person-years, respectively; P=0.018). The cumulative incidence of bleeding complications was not significantly different between the 2 groups. The mean prothrombin time-international normalized ratio (PT-INR) during warfarin on-treatment was <1.5 in 180 patients, 1.5–2.5 in 97 patients, and >2.5 in 6 patients. The incidence of bleeding complications was significantly higher in patients with PT-INR >2.5, whereas the incidence of recurrent VTE was not significantly different between the 3 PT-INR groups. The cumulative incidence of recurrent VTE and bleeding complications did not differ significantly among those in whom VTE was provoked by a transient risk factor, was unprovoked, or was associated with cancer.Conclusions: Warfarin therapy with an appropriate PT-INR according to Japanese guidelines is effective without increasing bleeding complications, regardless of patient characteristics.

Background:The association between direct oral anticoagulant (DOAC) dose and clinical outcomes when used with antiplatelets still remains to be investigated.Methods and Results:We conducted a prospective registry of non-valvular atrial fibrillation (AF) patients with DOAC: the DIRECT registry (n=2,216; follow-up, 407±388 days). We analyzed patients taking standard dose (n=907) and off-label reduced dose (n=338) DOAC in this sub-analysis. These patients were further stratified by add-on antiplatelets. Because DOAC dose was not randomly selected, potential confounding factors were eliminated through a propensity score-matching technique. The primary endpoint was clinically significant bleeding. The secondary endpoint was major adverse cardiovascular events (MACE; composite of all-cause death, all myocardial infarction, and stroke/systemic embolism). In patients with DOAC only/DOAC+antiplatelets, we successfully matched 212/62 patients who received off-label reduced dose DOAC with 212/62 standard dose patients. Off-label DOAC dose reduction did not have a significant impact on bleeding (HR, 1.123; 95% CI: 0.730–1.728, P=0.596) or MACE (HR, 1.107; 95% CI: 0.463–2.648, P=0.819) in patients with DOAC only, whereas in patients with add-on antiplatelets, off-label dose reduction significantly reduced bleeding (HR, 0.429; 95% CI: 0.212–0.868, P=0.019) without increasing MACE (HR, 2.205; 95% CI: 0.424–11.477, P=0.348).Conclusions:Reduced DOAC dose in combination with antiplatelet agents was associated with fewer bleeding complications than standard-dose therapy with no reduction in efficacy.

Background: The incidence of venous thromboembolism (VTE; pulmonary embolism [PE] and/or deep vein thrombosis [DVT]) in Japan is increasing, but relatively small numbers of patients from Japan have been included in studies investigating rivaroxaban (a direct factor Xa inhibitor) for the treatment of VTE and preventing its recurrence.Methods and Results: An open-label, prospective, observational study (XASSENT [NCT02558465]) investigated the safety profile and effectiveness of rivaroxaban for ≤2 years in the treatment of VTE and prevention of its recurrence in Japanese clinical practice. Primary outcomes were major bleeding and symptomatic recurrent VTE. Statistical analyses were exploratory and descriptive. Overall, 2,540 patients were enrolled (safety analysis population [SAP], n=2,387; effectiveness analysis population [EAP], n=2,386). In the SAP, >80% of patients received the approved rivaroxaban dose, the mean (standard deviation) age was 66.6 (15.0) years, ≈74% were >50 kg, and 43% had a creatinine clearance ≥80 mL/min. PE+DVT, PE only, and DVT only were reported in 42%, 8%, and 50% of patients, respectively, and active cancer in 17% of patients. Major bleeding was reported in 69 patients (2.89%; 3.60%/patient-year; SAP) and symptomatic PE/DVT recurrence in 26 patients (1.09%; 1.36%/patient-year; EAP) during the treatment period.Conclusions: XASSENT provided information on the expected proportions of bleeding and VTE recurrence during rivaroxaban treatment in Japanese clinical practice; no new concerns of safety or effectiveness were found.

Background:This study investigated the impact of systemic inflammation on bleeding risk in non-valvular atrial fibrillation (NVAF) patients treated with direct oral anticoagulants (DOAC).Methods and Results:We conducted a single-center prospective registry of 2,216 NVAF patients treated with DOAC: the DIRECT registry (UMIN000033283). High-sensitivity C-reactive protein (hsCRP) was measured ≤3 months before (pre-DOAC hsCRP) and 6±3 months after initiation of DOAC (post-DOAC hsCRP). Multivariate logistic regression model was used to assess the influence of systemic inflammation and conventional bleeding risk factors on major bleeding according to International Society on Thrombosis and Haemostasis criteria. Based on the findings, we created a new bleeding risk assessment score: the ORBIT-i score, which included post-DOAC hsCRP >0.100 mg/dL and all components of the ORBIT score. A total of 1,848 patients had both pre- and post-DOAC hsCRP data (follow-up duration, 460±388 days). Post-DOAC hsCRP was associated with major bleeding (OR, 2.770; 95% CI: 1.687–4.548, P<0.001). Patients with post-DOAC hsCRP >0.100 mg/dL more frequently had major bleeding than those without (log-rank test, P<0.001). ORBIT-i score had the highest C-index of 0.711 (95% CI, 0.654–0.769) compared with the ORBIT and HAS-BLED scores.Conclusions:Persistent systemic inflammation was associated with major bleeding risk. ORBIT-i score had a higher discriminative performance compared with the conventional bleeding risk scores.
