An Aspirin-Free Versus Dual Antiplatelet Strategy for Coronary Stenting: STOPDAPT-3 Randomized Trial.

BACKGROUND: Bleeding rates on dual antiplatelet therapy (DAPT) within 1 month after percutaneous coronary intervention (PCI) remain high in clinical practice, particularly in patients with acute coronary syndrome or high bleeding risk. Aspirin-free strategy might result in lower bleeding early after PCI without increasing cardiovascular events, but its efficacy and safety have not yet been proven in randomized trials. METHODS: We randomly assigned 6002 patients with acute coronary syndrome or high bleeding risk just before PCI either to prasugrel (3.75 mg/day) monotherapy or to DAPT with aspirin (81-100 mg/day) and prasugrel (3.75 mg/day) after loading of 20 mg of prasugrel in both groups. The coprimary end points were major bleeding (Bleeding Academic Research Consortium 3 or 5) for superiority and cardiovascular events (a composite of cardiovascular death, myocardial infarction, definite stent thrombosis, or ischemic stroke) for noninferiority with a relative 50% margin. RESULTS: The full analysis set population consisted of 5966 patients (no-aspirin group, 2984 patients; DAPT group, 2982 patients; age, 71.6±11.7 years; men, 76.6%; acute coronary syndrome, 75.0%). Within 7 days before randomization, aspirin alone, aspirin with P2Y12 inhibitor, oral anticoagulants, and intravenous heparin infusion were given in 21.3%, 6.4%, 8.9%, and 24.5%, respectively. Adherence to the protocol-specified antiplatelet therapy was 88% in both groups at 1 month. At 1 month, the no-aspirin group was not superior to the DAPT group for the coprimary bleeding end point (4.47% and 4.71%; hazard ratio, 0.95 [95% CI, 0.75-1.20]; Psuperiority=0.66). The no-aspirin group was noninferior to the DAPT group for the coprimary cardiovascular end point (4.12% and 3.69%; hazard ratio, 1.12 [95% CI, 0.87-1.45]; Pnoninferiority=0.01). There was no difference in net adverse clinical outcomes and each component of coprimary cardiovascular end point. There was an excess of any unplanned coronary revascularization (1.05% and 0.57%; hazard ratio, 1.83 [95%CI, 1.01-3.30]) and subacute definite or probable stent thrombosis (0.58% and 0.17%; hazard ratio, 3.40 [95% CI, 1.26-9.23]) in the no-aspirin group compared with the DAPT group. CONCLUSIONS: The aspirin-free strategy using low-dose prasugrel compared with the DAPT strategy failed to attest superiority for major bleeding within 1 month after PCI but was noninferior for cardiovascular events within 1 month after PCI. However, the aspirin-free strategy was associated with a signal suggesting an excess of coronary events. REGISTRATION: URL: https://www.clinicaltrials.gov; Unique identifier: NCT04609111.

Endovascular Therapy for Acute Stroke with a Large Ischemic Region.

BACKGROUND: Endovascular therapy for acute ischemic stroke is generally avoided when the infarction is large, but the effect of endovascular therapy with medical care as compared with medical care alone for large strokes has not been well studied. METHODS: We conducted a multicenter, open-label, randomized clinical trial in Japan involving patients with occlusion of large cerebral vessels and sizable strokes on imaging, as indicated by an Alberta Stroke Program Early Computed Tomographic Score (ASPECTS) value of 3 to 5 (on a scale from 0 to 10, with lower values indicating larger infarction). Patients were randomly assigned in a 1:1 ratio to receive endovascular therapy with medical care or medical care alone within 6 hours after they were last known to be well or within 24 hours if there was no early change on fluid-attenuated inversion recovery images. Alteplase (0.6 mg per kilogram of body weight) was used when appropriate in both groups. The primary outcome was a modified Rankin scale score of 0 to 3 (on a scale from 0 to 6, with higher scores indicating greater disability) at 90 days. Secondary outcomes included a shift across the range of modified Rankin scale scores toward a better outcome at 90 days and an improvement of at least 8 points in the National Institutes of Health Stroke Scale (NIHSS) score (range, 0 to 42, with higher scores indicating greater deficit) at 48 hours. RESULTS: A total of 203 patients underwent randomization; 101 patients were assigned to the endovascular-therapy group and 102 to the medical-care group. Approximately 27% of patients in each group received alteplase. The percentage of patients with a modified Rankin scale score of 0 to 3 at 90 days was 31.0% in the endovascular-therapy group and 12.7% in the medical-care group (relative risk, 2.43; 95% confidence interval [CI], 1.35 to 4.37; P = 0.002). The ordinal shift across the range of modified Rankin scale scores generally favored endovascular therapy. An improvement of at least 8 points on the NIHSS score at 48 hours was observed in 31.0% of the patients in the endovascular-therapy group and 8.8% of those in the medical-care group (relative risk, 3.51; 95% CI, 1.76 to 7.00), and any intracranial hemorrhage occurred in 58.0% and 31.4%, respectively (P<0.001). CONCLUSIONS: In a trial conducted in Japan, patients with large cerebral infarctions had better functional outcomes with endovascular therapy than with medical care alone but had more intracranial hemorrhages.

Aspirin versus Clopidogrel Monotherapy After Percutaneous Coronary Intervention: 1-Year Follow-up of the STOPDAPT-3 Trial.

BACKGROUND AND AIMS: There was no previous trial comparing aspirin monotherapy with a P2Y12 inhibitor monotherapy following short dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) with drug-eluting stents (DES). METHODS: In the STOPDAPT-3, patients with acute coronary syndrome (ACS) or high bleeding risk (HBR) were randomly assigned to either 1-month DAPT with aspirin and prasugrel followed by aspirin monotherapy (aspirin group) or 1-month prasugrel monotherapy followed by clopidogrel monotherapy (clopidogrel group). This secondary analysis compared aspirin monotherapy with clopidogrel monotherapy by the 30-day landmark analysis. The co-primary endpoints were the cardiovascular endpoint defined as a composite of cardiovascular death, myocardial infarction, definite stent thrombosis, or ischaemic stroke, and the bleeding endpoint defined as Bleeding Academic Research Consortium 3 or 5. RESULTS: Of 6002 assigned patients, 5833 patients (aspirin group: N = 2920 and clopidogrel group: N = 2913) were included in the 30-day landmark analysis. Median age was 73 (interquartile range 64-80) years, women 23.4%, ACS 74.6%, and HBR 54.1%. The assigned monotherapy was continued at 1 year in 87.5% and 87.2% in the aspirin and clopidogrel groups, respectively. The incidence rates beyond 30 days and up to 1 year were similar between the aspirin and clopidogrel groups for both cardiovascular endpoint (4.5 and 4.5 per 100 person-year, hazard ratio [HR] 1.00 [95% confidence interval (CI) 0.77-1.30], P = .97), and bleeding endpoint (2.0 and 1.9, HR 1.02 [95% CI 0.69-1.52], P = .92). CONCLUSIONS: Aspirin monotherapy compared to clopidogrel monotherapy was associated with similar cardiovascular and bleeding outcomes beyond 1 month and up to 1 year after PCI with DES.

Edoxaban for 12 Months Versus 3 Months in Patients With Cancer With Isolated Distal Deep Vein Thrombosis (ONCO DVT Study): An Open-Label, Multicenter, Randomized Clinical Trial.

BACKGROUND: The optimal duration of anticoagulation therapy for isolated distal deep vein thrombosis in patients with cancer is clinically relevant, but the evidence is lacking. The prolonged anticoagulation therapy could have a potential benefit for prevention of thrombotic events; however, it could also increase the risk of bleeding. METHODS: In a multicenter, open-label, adjudicator-blinded, randomized clinical trial at 60 institutions in Japan, we randomly assigned patients with cancer with isolated distal deep vein thrombosis, in a 1-to-1 ratio, to receive either a 12-month or 3-month edoxaban treatment. The primary end point was a composite of a symptomatic recurrent venous thromboembolism (VTE) or VTE-related death at 12 months. The major secondary end point was major bleeding at 12 months, according to the criteria of the International Society on Thrombosis and Haemostasis. The primary hypothesis was that a 12-month edoxaban treatment was superior to a 3-month edoxaban treatment with respect to the primary end point. RESULTS: From April 2019 through June 2022, 604 patients were randomized, and after excluding 3 patients who withdrew consent, 601 patients were included in the intention-to-treat population: 296 patients in the 12-month edoxaban group and 305 patients in the 3-month edoxaban group. The mean age was 70.8 years, 28% of the patients were men, and 20% of the patients had symptoms of deep vein thrombosis at baseline. The primary end point of a symptomatic recurrent VTE event or VTE-related death occurred in 3 of the 296 patients (1.0%) in the 12-month edoxaban group and in 22 of the 305 patients (7.2%) in the 3-month edoxaban group (odds ratio, 0.13; 95% CI, 0.03-0.44). The major secondary end point of major bleeding occurred in 28 of the 296 patients (9.5%) in the 12-month edoxaban group and in 22 of the 305 patients (7.2%) in the 3-month edoxaban group (odds ratio, 1.34; 95% CI, 0.75-2.41). The prespecified subgroups did not affect the estimates on the primary end point. CONCLUSIONS: In patients with cancer with isolated distal deep vein thrombosis, 12 months was superior to 3 months for an edoxaban treatment with respect to the composite outcome of a symptomatic recurrent VTE or VTE-related death.

Expanding the Treatable Imaging Profile in Patients With Large Ischemic Stroke: Subanalysis From a Randomized Clinical Trial.

BACKGROUND: We aimed to examine the boundary of the ischemic core volume in patients undergoing endovascular thrombectomy (EVT) versus those receiving medical management to determine the minimum optimal size for favorable treatment outcomes. METHODS: This is a prespecified substudy of the RESCUE-Japan LIMIT (Recovery by Endovascular Salvage for Cerebral Ultra-Acute Embolism-Japan Large Ischemic Core Trial). Patients with large vessel occlusion were enrolled between November 2018 and September 2021 with a National Institutes of Health Stroke Scale score of at least 6 on admission and an Alberta Stroke Program Early Computed Tomography Score value of 3 to 5. We investigated the correlation between optimal quantified ischemic core volume, assessed solely using magnetic resonance diffusion-weighted imaging, and functional outcomes (modified Rankin Scale score, 0-3) at 90 days by predictive marginal plots. Final infarct volume and safety outcomes (symptomatic intracerebral hemorrhage and mortality) were also assessed. RESULTS: Of the 203 cases, 168 patients (85 in the EVT group versus 83 in the medical management group) were included. The median (interquartile range) core volume was 94 (65-160) mL in patients with EVT and 115 (71-141) mL in the medical management group (P=0.72). The predictive marginal probabilities of the 2 groups intersected at 128 mL for estimating functional outcomes. Symptomatic intracerebral hemorrhage and mortality within 90 days had overlay margins through all core volumes in both groups. The median final infarct volume (interquartile range) was smaller in the EVT group (142 [80-223] mL versus 211 [123-289] mL in the medical management group; P<0.001). CONCLUSIONS: In this prespecified analysis of a randomized clinical trial involving patients with large ischemic strokes, patients with an estimated core volume of up to 128 mL on diffusion-weighted imaging benefit from EVT.

Differential Prognostic Impact of Clinical Congestion between Preserved versus Reduced Ejection Fraction in Patients Hospitalized for Acute Decompensated Heart Failure: Findings from the Japanese Kyoto Congestive Heart Failure Registry.

BACKGROUND: Most patients hospitalized for heart failure (HF) present with signs of congestion. Prognostic significance of clinical congestion may vary depending on left ventricular ejection fraction (LVEF). This study aims to investigate the prognostic impact of congestion across different LVEF categories. METHODS AND RESULTS: Composite congestion scores (CCSs; 0-9) derived from the severity of edema, jugular venous pressure, and orthopnea, were analyzed on admission and at discharge in 3787 patients hospitalized for HF (LVEF ≥ 40%: n = 2347, LVEF < 40%: n = 1440). The median admission CCS was 4 in both LVEF strata (P = .64). Adjusted hazard ratios (HRs; 95% confidence interval [CI]) of the moderate (CCS 4-6) and severe congestion [7-9] groups relative to the mild congestion [0-3] group on admission for a composite of all-cause death or HF rehospitalization were 1.20 (1.04-1.39, P = .01) and 1.54 (1.27-1.86, P < .001) in the LVEF ≥ 40% stratum, and 1.20 (1.01-1.44, P = .04) and 0.82 (0.61-1.07, P = .14) in the LVEF < 40% stratum, respectively (Pinteraction< .001). A total of 16% of the patients with LVEF ≥40% and 14% with LVEF <40% had residual congestion (CCS ≥ 1) at discharge, which was associated with a respective adjusted HR of 1.40 (1.18-1.65, P < .001) and 1.25 (0.98-1.58, P = .07) for postdischarge death or HF rehospitalization (Pinteraction = 0.63). CONCLUSION: The severity of clinical congestion on admission was associated with adverse clinical outcomes in patients with LVEF ≥ 40%, but not in those with LVEF < 40%. These findings warrant further studies to better understand the detailed profile of congestion across the LVEF spectrum.

Long-Term Effects of Proton Pump Inhibitors in Patients Undergoing Percutaneous Coronary Intervention in High-Risk Subgroups.

BACKGROUND: Proton pump inhibitors (PPIs) reportedly reduce upper gastrointestinal bleeding (UGIB) in patients undergoing percutaneous coronary intervention (PCI). However, whether the benefits of PPIs differ in high-risk subgroups is unknown. METHODS AND RESULTS: Among 24,563 patients undergoing first PCI in the CREDO-Kyoto registry Cohort-2 and -3, we evaluated long-term effects of PPI for UGIB, defined as GUSTO moderate/severe bleeding, in several potential high-risk subgroups. In the study population, 45.6% of patients were prescribed PPIs. Over a median 5.6-year follow-up, PPIs were associated with lower adjusted risk of UGIB (hazard ratio [HR] 0.64; 95% confidence interval [CI] 0.50-0.80; P<0.001) and a non-significant but numerically lower risk of any gastrointestinal bleeding (HR 0.84; 95% CI 0.71-1.01; P=0.06). PPIs were not associated with a lower risk of GUSTO moderate/severe bleeding (HR 1.04; 95% CI 0.94-1.15; P=0.40) or a higher adjusted risk of myocardial infarction or ischemic stroke (HR 1.00; 95% CI 0.90-1.12; P=0.97), but were associated with higher adjusted mortality risk (HR 1.18; 95% CI 1.09-1.27; P<0.001). The effects of PPIs for UGIB, myocardial infarction or ischemic stroke, and all-cause death were consistent regardless of age, sex, acute coronary syndrome, high bleeding risk, oral anticoagulant use, and type of P2Y12inhibitor. CONCLUSIONS: PPIs were associated with a lower risk of UGIB and a neutral risk of ischemic events regardless of high-risk subgroup.

Impact of Anemia on Clinical Outcomes of Patients With Cancer-Associated Isolated Distal Deep Vein Thrombosis Receiving Edoxaban　- Insights From the ONCO DVT Study.

BACKGROUND: The ONCO DVT study demonstrated potential benefits of extended edoxaban treatment in patients with isolated distal deep vein thrombosis in terms of thrombotic risk. However, the risk-benefit balance in patients with anemia remains unclear. METHODS AND RESULTS: This prespecified subgroup analysis included 601 patients, divided into anemia (n=402) and no-anemia (n=199) groups. The primary endpoint was symptomatic recurrent venous thromboembolism (VTE) or VTE-related death. Anemia was defined as hemoglobin <12 g/dL for women and <13 g/dL for men. In the anemia subgroup, the primary endpoint occurred in 3 (1.5%) and 17 (8.4%) patients in the 12- and 3-month edoxaban treatment groups, respectively (odds ratio [OR] 0.17; 95% confidence interval [CI] 0.05-0.58), compared with 0 and 5 (4.9%) patients, respectively, in the no-anemia subgroup (P interaction=0.997). Major bleeding occurred in 26 (13.1%) and 17 (8.4%) patients with anemia in the 12- and 3-month edoxaban treatment groups, respectively (OR 1.64; 95% CI 0.86-3.14), compared with 2 (2.1%) and 5 (4.9%) patients without anemia (OR 0.67; 95% CI 0.26-1.73; P interaction=0.13). CONCLUSIONS: Regardless of the presence of anemia, edoxaban treatment for 12 months was superior to treatment for 3 months in reducing thrombotic events, whereas the risk of major bleeding did not differ significantly between the 2 treatment groups.

Radiofrequency Catheter Ablation for Atrial Fibrillation Patients on Hemodialysis (From the Kansai Plus Atrial Fibrillation Registry)　- Clinical Impact of Early Recurrence.

BACKGROUND: Catheter ablation (CA) for atrial fibrillation (AF) in patients on hemodialysis (HD) is reported to have a high risk of late recurrence (LR). However, the relationship between early recurrence (ER) within a 90-day blanking period after CA in AF patients and LR in HD patients remains unclear. METHODS AND RESULTS: Of the 5,010 patients in the Kansai Plus Atrial Fibrillation Registry, 5,009 were included in the present study. Of these patients, 4,942 were not on HD (non-HD group) and 67 were on HD (HD group). HD was an independent risk factor for LR after the initial CA (adjusted hazard ratio 1.6; 95% confidence interval 1.1-2.2; P=0.01). In patients with ER, the rate of sinus rhythm maintenance at 3 years after the initial CA was significantly lower in the HD than non-HD group (11.4% vs. 35.4%, respectively; log-rank P=0.004). However, in patients without ER, there was no significant difference in the rate of sinus rhythm maintenance at 3 years between the HD and non-HD groups (67.7% vs. 74.5%, respectively; log-rank P=0.62). CONCLUSIONS: ER in HD patients was a strong risk factor for LR. However, even HD patients could expect a good outcome without ER after the initial CA.

Association Between White Blood Cell Counts at Diagnosis and Clinical Outcomes in Venous Thromboembolism　- From the COMMAND VTE Registry-2.

BACKGROUND: White blood cell (WBC) counts were reported to be a risk factor for acute adverse events in patients with venous thromboembolism (VTE). However, there are limited data on VTE patients without active cancer. METHODS AND RESULTS: The COMMAND VTE Registry-2 was a multicenter study enrolling 5,197 consecutive patients with acute symptomatic VTE. We divided 3,668 patients without active cancer into 4 groups based on WBC count quartiles (Q1-Q4) at diagnosis: Q1, ≤5,899 cells/µL; Q2, 5,900-7,599 cells/µL, Q3, 7,600-9,829 cells/µL; and Q4, ≥9,830 cells/µL. Patients in Q4 more often presented with pulmonary embolism (PE) than patients in Q1, Q2, and Q3 (68% vs. 37%, 53%, and 61%, respectively; P<0.001). The proportion of massive PEs among all PEs was higher in Q4 than in Q1, Q2, and Q3 (21% vs. 3.4%, 5.8%, and 11%, respectively; P<0.001). Compared with Q1, Q2, and Q3, patients in Q4 had a higher cumulative 5-year incidence of all-cause death (17.0%, 15.2%, 16.1%, and 22.8%, respectively; P<0.001) and major bleeding (10.9%, 11.0%, 10.3%, and 14.4%, respectively; P=0.002). The higher mortality risk of Q4 relative to Q2 was consistent regardless of the presentations of VTEs. CONCLUSIONS: An elevated WBC count on VTE diagnosis was associated with a higher risk of mortality and major bleeding regardless of VTE presentation, suggesting the potential usefulness of WBC counts for further risk stratification.

Home Treatment for Active Cancer Patients With Low-Risk Pulmonary Embolism　- A Predetermined Companion Report From the ONCO PE Trial.

BACKGROUND: Patients with appropriately selected low-risk pulmonary embolism (PE) can be treated at home, although it has been controversial whether applies to patients with cancer, who are considered not to be at low risk.Methods and Results: The current predetermined companion report from the ONCO PE trial evaluated the 3-month clinical outcomes of patients with home treatment and those with in-hospital treatment. The ONCO PE trial was a multicenter, randomized clinical trial among 32 institutions in Japan investigating the optimal duration of rivaroxaban treatment in cancer-associated PE patients with a score of 1 using the simplified version of the Pulmonary Embolism Severity Index (sPESI). Among 178 study patients, there were 66 (37%) in the home treatment group and 112 (63%) in the in-hospital treatment group. The primary endpoint of a composite of PE-related death, recurrent venous thromboembolism (VTE) and major bleeding occurred in 3 patients (4.6% [0.0-9.6%]) in the home treatment group and in 2 patients (1.8% [0.0-4.3%]) in the in-hospital treatment group. In the home treatment group, there were no cases of PE-related death or recurrent VTE, but major bleeding occurred in 3 patients (4.6% [0.0-9.6%]), and 2 patients (3.0% [0.0-7.2%]) required hospitalization due to bleeding events. CONCLUSIONS: Active cancer patients with PE of sPESI score=1 could be potential candidates for home treatment.

Concomitant Mitral Regurgitation in Severe Aortic Stenosis　- Insights From the CURRENT AS Registry-2.

BACKGROUND: Data on concomitant mitral regurgitation (MR) in patients with severe aortic stenosis (AS) are scarce.Methods and Results: We investigated the risk of concomitant MR in patients with severe AS in the CURRENT AS Registry-2 according to initial treatment strategy (transcatheter aortic valve implantation [TAVI], surgical aortic valve replacement [SAVR], or conservative). Among 3,365 patients with severe AS, 384 (11.4%) had moderate/severe MR (TAVI: n=126/1,148; SAVR: n=68/591; conservative: n=190/1,626). The cumulative 3-year incidence for death or heart failure (HF) hospitalization was significantly higher in the moderate/severe than no/mild MR group in the entire population (54.6% vs. 34.3%, respectively; P<0.001) and for each treatment strategy (TAVI: 45.0% vs. 31.8% [P=0.006]; SAVR: 31.9% vs. 18.7% [P<0.001]; conservative: 67.8% vs. 41.6% [P<0.001]). The higher adjusted risk of moderate/severe MR relative to no/mild MR for death or HF hospitalization was not significant in the entire population (hazard ratio [HR] 1.15; 95% confidence interval [CI] 0.95-1.39; P=0.15); however, the risk was significant in the SAVR (HR 1.92; 95% CI 1.04-3.56; P=0.04) and conservative (HR 1.30; 95% CI 1.02-1.67; P=0.04) groups, but not in the TAVI group (HR 1.03; 95% CI 0.70-1.52; P=0.86), despite no significant interaction (Pinteraction=0.37). CONCLUSIONS: Moderate/severe MR was associated with a higher risk for death or HF hospitalization in the initial SAVR and conservative strategies, while the association was less pronounced in the initial TAVI strategy.

The Risk of Metastatic Recurrence after Non-Curative Endoscopic Resection with Negative Deep Margins for Early Colorectal Cancer: Two-Center Retrospective Cohort Study.

INTRODUCTION: Non-curative endoscopic resection of T1 colorectal cancer (CRC) carries a substantial risk of recurrence. However, previous studies have reported a significant proportion of cases in which the deep margin of endoscopic resection was positive for cancer due to the technical difficulties of colorectal endoscopic submucosal dissection (ESD). With the advancement of endoscopic technology and techniques resulting in the reduction of positive resection margins, it is important to reassess the long-term prognosis and major risk factors for recurrence in cases of negative deep margins. METHODS: We conducted a retrospective cohort study of consecutive patients with T1 CRC who underwent endoscopic resection between January 2006 and December 2021 with negative deep margins. The histological findings of the resected specimens were analyzed to determine the risk factors associated with the primary outcomes of this study, including recurrence and cancer-related deaths. RESULTS: The median age of the 190 patients was 70 years, of which 63% were male, and endoscopic treatment was performed in 64% by endoscopic mucosal resection and 36% by ESD. Eighty-two patients were in the curative resection (CR) group and 108 were in the non-curative resection (NCR) group, wherein the latter comprised 79 patients who underwent additional surgery (AS) and 29 patients who did not receive AS. Five-year recurrence-free survival rates were 98.4% (95% CI: 89.3-99.8) for CR, 98.3% (95% CI: 88.8-99.8) for NCR with AS, and 73.7% (95% CI: 46.5-88.5) for NCR without AS. Lymphatic invasion and budding grade 2/3 were the major risk factors for recurrence, with hazard ratios of 40.7 (p < 0.001) and 23.1 (p = 0.007), respectively. Of the patients in the NCR group without AS, the 5-year recurrence-free rate was 85.6% (95% CI: 52.5-96.3) if there were no major risk factors (i.e., no lymphatic invasion or budding grade 2/3) (n = 21), whereas the prognosis was poor in the presence of one or more of the major risk factors, with a median recurrence-free survival and disease-specific survival of 2.5 and 3.1 years, respectively (n = 8). DISCUSSION: In endoscopically resected T1 CRC with negative deep margins, lymphatic invasion or budding grade 2/3 may indicate a higher risk of recurrence when followed up without AS.

One-year morbidity and mortality in patients treated with standard-dose and low-dose apixaban after acute large vessel occlusion stroke.

Although low-dose direct oral anticoagulants (DOACs) are recommended for patients at high risk of bleeding complications, it remains unclear whether the dose reduction in real-world setting is also appropriate in patients after large-vessel occlusion (LVO) stroke. This study hypothesized that patients with atrial fibrillation (AF) and LVO receiving low-dose DOACs have an increased risk of ischemic and hemorrhagic events. The study aimed to assess 1 year morbidity and mortality in patients treated with standard-dose and low-dose apixaban after LVO stroke. A post hoc analysis was performed using the acute LVO registry data, which enrolled patients with AF and LVO who received apixaban within 14 days of stroke onset. The incidences of ischemic events (ischemic stroke, acute coronary syndrome, acute myocardial infarction, and systemic embolism), major bleeding events, and death from any cause were compared between patients receiving standard- and low-dose apixaban. Of 643 patients diagnosed with LVO, 307 (47.7%) received low-dose apixaban. After adjustment for clinically relevant variables, no significant differences were observed in the incidence of ischemic events (adjusted hazard ratio [aHR]: 2.12, 95% confidence interval [CI] 0.75-6.02), major bleeding events (aHR: 1.17, 95% CI 0.50-2.73), and death from any cause (aHR: 1.95, 95% CI 0.78-4.89) between patients receiving standard- and low-dose apixaban. No significant differences were observed in the incidence of ischemic events, major bleeding events, or death from any cause between patients with AF and LVO receiving standard- and low-dose apixaban.

Initial hemodynamic status and Acute Mortality in Cancer patients with Acute Pulmonary Embolism: from the COMMAND VTE Registry.

BACKGROUND: Initial hemodynamic status in patients with acute pulmonary embolism (PE) concerns their acute clinical outcomes. Nevertheless, the characteristics of initial hemodynamic dysfunction and acute mortality in PE patients with active cancer is still controversial. METHODS: We analyzed the data of 1715 PE patients in the COMMAND VTE Registry to compare initial hemodynamic dysfunction, management strategies, and mortality outcomes at 30 days after PE diagnosis between patients with and without active cancer (N = 393 and N = 1322). RESULTS: The patients with active cancer showed lower prevalence of right ventricular dysfunction (35.4% vs. 49.5%, P < 0.001), shock (6.4% vs. 11.6%, P = 0.003), and cardiac arrest (1.8% vs. 5.5%, P = 0.002) at PE diagnosis, compared with those without. The patients with active cancer less frequently received systemic thrombolysis (4.1% vs. 12.6%, P < 0.001) than those without. There was no significant difference in the cumulative 30-day incidence of PE-related death between patients with and without active cancer (4.1% vs. 4.2%, P = 0.89). The cumulative 30-day incidence of all-cause death was significantly higher in patients with active cancer than in those without (11.5% vs. 4.9%, P < 0.001). CONCLUSIONS: PE patients with active cancer less frequently present with initial hemodynamic dysfunction at PE diagnosis, compared with those without. Nevertheless, PE patients with active cancer still show a similar risk of PE-related death and a higher risk of all-cause death at 30 days after PE diagnosis, suggesting the importance of prudent management for this patient population even if their initial hemodynamic status are not compromised.

Statins use and recurrent venous thromboembolism in the direct oral anticoagulant era: insight from the COMMAND VTE Registry-2.

Statins were reported to have a potential effect of primary prevention of venous thromboembolism (VTE), although that of secondary prevention remains uncertain. To investigate the association between statins use and recurrent VTE in the current era. The COMMAND VTE Registry-2 is a multicenter registry enrolling 5,197 consecutive VTE patients among 31 centers in Japan between January 2015 and August 2020. We divided the entire cohort into 2 groups according to statins use at the time of discharge; the statins (N = 865) and no statins groups (N = 4332). The statins group was older (72.9 vs. 66.7 years, P < 0.001), and less often had active cancer (22.0% vs. 30.4%, P < 0.001). The cumulative incidence of discontinuation of anticoagulation was significantly lower in the statins group (60.3% vs. 52.6%, Log-rank P < 0.001). The cumulative 5-year incidence of recurrent VTE was significantly lower in the statins group (6.8% vs. 10.1%, Log-rank P = 0.01). Even after adjusting for the confounders, the lower risk of the statins group relative to the no statins group remained significant for recurrent VTE (HR 0.65, 95% CI 0.45-0.91, P = 0.01). The cumulative 5-year incidence of major bleeding was significantly lower in the statins group (12.2% vs. 14.1%, Log-rank P = 0.04), although, after adjusting for the confounders, the risk of the statins group relative to the no statins group turned to be insignificant (HR 0.77, 95% CI 0.59-1.00, P = 0.054). In this large real-world VTE registry, statins use was significantly associated with a lower risk for the recurrent VTE in the current era.

Anemia and Rehabilitation Outcomes in Patients Undergoing Convalescent Rehabilitation.

OBJECTIVE: Assessment of the association between anemia and recovery of physical disability in patients with functional impairment. DESIGN: A retrospective cohort study. SETTING: A convalescent rehabilitation ward. PARTICIPANTS: The subjects were patients undergoing convalescent rehabilitation due to neurologic disease, musculoskeletal disorders, or hospital-associated deconditioning. Patients were classified into 3 groups (no anemia; mild anemia [men: hemoglobin of 11.0-12.9 g/dL; women: hemoglobin of 11.0-11.9 g/dL]; and moderate/severe anemia [hemoglobin < 11.0 g/dL]) based on hemoglobin levels. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The study outcomes were functional independence measures for motor function (FIM-M) score at discharge, changes in the FIM-M score between hospital admission and discharge, length of stay, and FIM-M efficiency score (change in FIM-M score divided by length of stay). A linear regression model was constructed to explore the association of anemia with the FIM-M efficiency score. As a subgroup analysis, we constructed a linear regression model to explore the association of anemia with the FIM-M efficiency score in patients with or without stroke. RESULTS: Of 376 consecutive patients with a mean age of 80 years, 258 (69%) had mild or moderate/severe anemia. There were no significant differences between the 3 groups in the FIM-M score at discharge, changes in the FIM-M score, length of stay, and FIM-M efficiency score. A multiple linear regression model showed that the FIM-M efficiency score was not associated with anemia (mild anemia group: ß=-0.02, P=.8; moderate/severe anemia group: ß=-0.005, P=.9). In the subgroup analysis of patients with or without stroke, the multiple regression model also showed no significant association between anemia and FIM-M efficiency score in each group. CONCLUSIONS: Anemia on admission was common among patients in a convalescent rehabilitation ward but was not associated with improvement of FIM-M after rehabilitation.

Declining trend in the estimated annual rupture rate of unruptured cerebral aneurysms in Japan: a nationwide study.

The incidence of subarachnoid hemorrhages (SAHs) in Japan has recently decreased. However, trends in the annual rates of unruptured cerebral aneurysms (UCAs) are unclear because calculations based on follow-up periods are limited to patients with ruptured cerebral aneurysms. We aimed to clarify current trends in the estimated annual rupture rates of UCAs in Japan and to identify the most relevant contributing factors. We analyzed data from the Japanese Ministry of Health, Labour and Welfare and records of the Japan Neurosurgical Society. The estimated annual rupture rates of UCAs between 2003 and 2018 were calculated according to age-adjusted mortality rates of SAH and number of treated ruptured cerebral aneurysms (RCAs). We estimated trends in annual rupture rates using sensitivity analysis and assessed associations between estimated annual rupture rates and the prevalences of hypertension and current smoking. The estimated annual rupture rate of UCAs significantly decreased from 1.44 to 0.87% and from 0.92 to 0.76%, respectively, in terms of age-adjusted mortality rates of SAH and number of treated RCAs (p < 0.001). The range of changes in estimated annual rupture rates of UCAs was - 1.13%‒0.83%, representing a declining UCA trend of 88%. The estimated annual rupture rates of UCAs declined by 0.02-0.10% and 0.01-0.05% with every percent decrease in hypertension and current smoking prevalence, respectively. The estimated annual rupture rate of UCAs has recently decreased in Japan, possibly due to a decrease in the prevalence of hypertension rather than smoking.

Incidence of and factors associated with emergency caesarean section in pregnant women with gestational diabetes mellitus: A retrospective cohort study.

AIM: The incidence of factors associated with emergency cesarean section (ECS) in patients with gestational diabetes mellitus (GDM) have not been well investigated. METHODS: We conducted a retrospective cohort study of patients diagnosed with GDM between 2011 and 2020 at a tertiary care hospital in Japan. Clinical data, vital signs, and laboratory results of the patients were collected from electronic medical records. We constructed a multivariate logistic regression model to identify the clinical characteristics associated with ECS. RESULTS: We included 1189 patients diagnosed with GDM, the mean maternal age was 33 years, and 507 (42.6%) patients were aged ≥35 years. In total, 114 patients underwent ECS (9.6%). The previous assisted reproductive technology (ART) use (odds ratio [OR], 1.81; 95% confidence interval [CI], 1.12-2.93), previous artificial abortion (OR, 1.94; 95% CI, 1.13-3.33), high pre-pregnancy body mass index (BMI) (OR, 1.07; 95% CI, 1.02-1.11), and late diagnosis of GDM (OR, 1.02; 95% CI, 1.003-1.05) were independently associated with ECS. CONCLUSIONS: One of every 10 GDM patients required ECS. Previous ART use, previous artificial abortion, high pre-pregnancy BMI, and late diagnosis of GDM were risk factors for ECS in GDM patients.

Number of Passes of Endovascular Therapy for Stroke With a Large Ischemic Core: Secondary Analysis of RESCUE-Japan LIMIT.

BACKGROUND: The increased risk of intracranial hemorrhage with multiple passes in endovascular therapy (EVT) for large vessel occlusion with a large ischemic core is a concern. We explored the effect of the number of EVT passes on patients in a randomized clinical trial. METHODS: This post hoc study was the secondary analysis of RESCUE-Japan LIMIT, which was a randomized clinical trial comparing EVT and medical treatment alone for large vessel occlusion with large ischemic core. We grouped patients according to the number of passes with successful reperfusion (modified Thrombolysis in Cerebral Infarction score, ≥2b) in 1, 2, and 3 to 7 passes and failed reperfusion (modified Thrombolysis in Cerebral Infarction score, 0-2a) after any pass in the EVT group, and these groups were compared with medical treatment group. The primary outcome was modified Rankin Scale score of 0 to 3 at 90 days. Secondary outcomes were improvement in National Institutes of Health Stroke Scale score of ≥8 at 48 hours, mortality at 90 days, symptomatic intracranial hemorrhage, and any intracranial hemorrhage within 48 hours. RESULTS: The number of patients who received EVT with successful reperfusion after 1, 2, and 3 to 7 passes and failed reperfusion were 44, 23, 19, and 14, respectively, and 102 received medical treatment alone. The adjusted odds ratios (95% CIs) for the primary outcome relative to medical treatment were 5.52 (2.23-14.28) after 1 pass, 6.45 (2.22-19.30) after 2 passes, 1.03 (0.15-4.48) after 3 to 7 passes, and 1.17 (0.16-5.37) if reperfusion failed. The adjusted odds ratios (95% CIs) for any intracranial hemorrhage within 48 hours relative to medical treatment were 1.88 (0.90-3.93) after 1 pass, 5.14 (1.97-14.72) after 2 passes, 3.00 (1.09-8.58) after 3 to 7 passes, and 6.16 (1.87-24.27) if reperfusion failed. CONCLUSIONS: The successful reperfusion within 2 passes was associated with better clinical outcomes. REGISTRATION: URL: https://www. CLINICALTRIALS: gov; Unique identifier: NCT03702413.
