An aspirin-free strategy for percutaneous coronary intervention in patients with diabetes: a pre-specified subgroup analysis of the STOPDAPT-3 trial.

AIMS: Safety of aspirin-free strategy immediately after percutaneous coronary intervention (PCI) for cardiovascular events in patients with diabetes was unknown. METHODS AND RESULTS: We conducted the prespecified subgroup analysis on diabetes in the STOPDAPT-3 trial, which randomly compared prasugrel (3.75 mg/day) monotherapy (2984 patients) to dual antiplatelet therapy (DAPT) with prasugrel and aspirin (2982 patients) in patients with acute coronary syndrome or high bleeding risk. The co-primary endpoints were major bleeding events (Bleeding Academic Research Consortium 3 or 5) and cardiovascular events (a composite of cardiovascular death, myocardial infarction, definite stent thrombosis, or stroke) at 1 month. Of 5966 study patients, there were 2715 patients (45.5%) with diabetes. Patients with diabetes more often had chronic coronary syndrome, heart failure or cardiogenic shock, and comorbidities than those without. Patients with diabetes compared to those without had higher incidences of major bleeding and cardiovascular events. Regardless of diabetes, the effect of no-aspirin relative to DAPT was not different for the co-primary bleeding (diabetes: 5.05% versus 5.47%; HR, 0.92; 95%CI, 0.66-1.28 and non-diabetes: 3.99% versus 4.07%; HR, 0.98; 95%CI, 0.69-1.38; P for interaction = 0.81) and cardiovascular (diabetes: 5.54% versus 5.15%; HR, 1.08; 95%CI, 0.78-1.49 and non-diabetes: 2.95% versus 2.47%; HR, 1.20; 95%CI, 0.79-1.82; P for interaction = 0.70) endpoints. The incidences of subacute definite or probable stent thrombosis and any coronary revascularization were higher in the no-aspirin group than in the DAPT group regardless of diabetes. CONCLUSIONS: The effects of an aspirin-free prasugrel monotherapy (3.75 mg/day) relative to DAPT for major bleeding and cardiovascular events were not different regardless of diabetes. Clinical trial registration: ShorT and OPtimal duration of Dual AntiPlatelet Therapy after everolimus-eluting cobalt-chromium stent-3 [STOPDAPT-3]; NCT04609111.

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.

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.

Incidence of Chronic Thromboembolic Pulmonary Hypertension After Pulmonary Embolism in the Era of Direct Oral Anticoagulants: From the COMMAND VTE Registry-2.

BACKGROUND: Chronic thromboembolic pulmonary hypertension (CTEPH) is a life-threatening complication post-acute pulmonary embolism (PE). The assessment of CTEPH incidence and risk factors post-acute PE in the era of direct oral anticoagulants remains insufficient. METHODS AND RESULTS: The COMMAND VTE Registry-2 (contemporary management and outcomes in patients with venous thromboembolism registry-2) is a multicenter registry that recruited consecutive patients with acute symptomatic venous thromboembolism from 31 centers across Japan. The primary outcome was to demonstrate the detection rate of CTEPH after acute PE in routine clinical practice. Out of the 5197 patients with venous thromboembolism included in the COMMAND VTE Registry-2, 2787 were diagnosed with acute PE. Following a median follow-up duration of 747 days, 48 cases of CTEPH were detected, and the cumulative diagnosis of CTEPH in routine clinical practice was 2.3% at 3 years. Independent risk factors for the detection of CTEPH by multivariable Cox regression analysis included women (hazard ratio [HR] 2.09 [95% CI, 1.05-4.14]), longer interval from symptom onset to diagnosis of PE (each 1 day, HR 1.04 [95% CI, 1.01-1.07]), hypoxemia at diagnosis (HR 2.52 [95% CI, 1.26-5.04]), right heart load (HR 9.28 [95% CI, 3.19-27.00]), lower D-dimer value (each 1 µg/mL, HR 0.96 [95% CI, 0.92-0.99]), and unprovoked PE (HR 2.77 [95% CI, 1.22-6.30]). CONCLUSIONS: In the direct oral anticoagulant era, the cumulative diagnosis of CTEPH after acute PE was 2.3% at 3 years, and several independent risk factors for CTEPH were identified, which could be useful for screening a high-risk population after acute PE.

Selection of Home Treatment and Identification of Low-Risk Patients With Pulmonary Embolism Based on Simplified Pulmonary Embolism Severity Index Score in the Era of Direct Oral Anticoagulants.

BACKGROUND: The simplified Pulmonary Embolism Severity Index (sPESI) score could help identify low-risk patients with pulmonary embolism for home treatment. However, the application of the sPESI score and selection for home treatment have not been fully evaluated in the direct oral anticoagulants era. METHODS AND RESULTS: The COMMAND VTE (Contemporary Management and Outcomes in Patients With Venous Thromboembolism) Registry-2 is a multicenter registry enrolling consecutive patients with acute symptomatic venous thromboembolism. The current study population consists of 2496 patients with hemodynamically stable pulmonary embolism (2100 patients [84%] treated with direct oral anticoagulants), who were divided into 2 groups: sPESI scores of 0 and ≥1. We investigated the 30-day mortality, home treatment prevalence, and factors predisposing to home treatment using the Kaplan-Meier method and logistic regression model. Patients with an sPESI score of 0 accounted for 612 (25%) patients, and only 17% among 532 patients with out-of-hospital pulmonary embolism were treated at home. The cumulative 30-day mortality was lower in patients with an sPESI score of 0 than the score of ≥1 (0% and 4.8%, log-rank P<0.001). There was no patient with 30-day mortality with an sPESI score of 0. Independent factors for home treatment among out-of-hospital pulmonary embolism patients with an sPESI score of 0 were no transient risk factors for venous thromboembolism, no cardiac biomarker elevation, and direct oral anticoagulants use in the acute phase. CONCLUSIONS: The 30-day mortality rate was notably low in an sPESI score of 0. Nevertheless, only a minority of patients with an sPESI score of 0 were treated at home between 2015 and 2020 after the introduction of direct oral anticoagulants for venous thromboembolismin Japan.

Utility of the modified Ottawa score for identification of more preferable candidates of extended anticoagulation therapy in cancer-associated isolated distal deep vein thrombosis: insight from the ONCO DVT Study.

BACKGROUND: The ONCO DVT study (Edoxaban for 12 Months Versus 3 Months in Patients With Cancer With Isolated Distal Deep Vein Thrombosis) revealed superiority of 12-month relative to 3-month edoxaban treatment for the thrombotic risk in cancer-associated isolated distal deep vein thrombosis. However, it is unknown whether the superiority could be common in different modified Ottawa score subgroups. OBJECTIVES: To identify more preferable candidates for extended anticoagulation in patients with cancer-associated isolated distal deep vein thrombosis using the modified Ottawa score. METHODS: In this post-hoc subgroup analysis of the ONCO DVT study, we stratified 601 patients into the low (≤-1, N = 126), intermediate (0, N = 323), and high (≥1, N = 152) modified Ottawa score subgroups and compared clinical outcomes between the 12-month and 3-month edoxaban treatment groups. RESULTS: The cumulative incidence of symptomatic recurrent venous thromboembolism or venous thromboembolism-related death was not different between the 12-month and 3-month edoxaban treatment groups in the low score subgroup (0.0% vs 2.2%), whereas it was lower in the 12-month than in the 3-month edoxaban treatment group in the intermediate (0.8% vs 7.6%) and high (3.1% vs 15.6%) score subgroups. There were no significant differences in the cumulative incidences of the major bleeding between the 12-month and 3-month edoxaban treatment groups in the low (10.1% vs 7.6%), intermediate (8.8% vs 5.0%), and high (13.9% vs 12.6%) score subgroups. CONCLUSION: A 12-month compared with 3-month edoxaban treatment showed a lower risk of thrombotic events in patients with cancer-associated isolated distal deep vein thrombosis in the intermediate and high modified Ottawa score subgroups but not in the low score subgroup, suggesting a limited benefit of extended anticoagulation therapy beyond 3 months in patients with low modified Ottawa score.

Characteristics and prognostic impact of unsuccessful recanalization after endovascular therapy for acute ischemic stroke.

BACKGROUND: Endovascular therapy (EVT) has shown high therapeutic efficacy for acute large vessel occlusion (LVO); however, recanalization is unsuccessful in some cases. This study aimed to examine the characteristics and prognostic impact of unsuccessful recanalization after EVT compared with medical treatment alone. METHODS: We conducted a post hoc analysis of RESCUE-Japan Registry 2, a nationwide registry of 2408 consecutive patients with acute LVO. Patients without successful recanalization after EVT (thrombolysis in cerebral infarction grade ≤ 2a) were classified into the Unsuccessful EVT group, and compared with the No-EVT group. To account for selection bias, the outcomes were compared in a propensity score-matched cohort. The outcomes included the modified Rankin Scale (mRS) score at 90 days and intracranial hemorrhage within 72 h after the LVO onset. RESULTS: Among 188 (14.7 %) patients in the Unsuccessful EVT group out of 1281 who underwent EVT, 147 were matched with the No-EVT group, with comparable baseline characteristics. Patients in the Unsuccessful EVT group had a higher distribution of mRS score at 90 days and were less likely to achieve mRS 0-2 compared to those in the No-EVT group (23 % vs. 34 %, OR:0.58, 95 % CI:0.35-0.98). All-cause mortality was higher in the Unsuccessful EVT group (16 % vs. 6.8 %, OR: 2.54, 95 % CIs: 1.16-5.55). Symptomatic intracranial hemorrhage was more frequently observed in the Unsuccessful EVT group (5.4 % vs. 0.7 %, OR: 8.40, 95 % CIs: 1.04-68.1). CONCLUSIONS: The clinical outcomes of patients without successful recanalization after EVT were worse than those who did not undergo EVT.

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.

Long-Term Effects of Low-Dose Aspirin on Gastrointestinal Symptoms and Bleeding Complications in Patients with Type 2 Diabetes.

BACKGROUND: Low-dose aspirin for primary prevention is determined by the balance of risks of cardiovascular events and adverse effects. We assessed the long-term gastrointestinal symptoms or bleeding with low-dose aspirin in diabetic patients. METHODS: The Japanese Primary Prevention of Atherosclerosis with Aspirin for Diabetes (JPAD) trial was a randomized clinical trial to evaluate the efficacy and safety of low-dose aspirin in patients with type 2 diabetes. As a post hoc analysis, we investigated the incidence of upper gastrointestinal symptoms or bleeding in aspirin (100 mg enteric-coated aspirin or 81 mg buffered aspirin daily) and no-aspirin groups within and beyond 3 years. RESULTS: Of 2535 patients (mean age 65 years, 55% male) followed for a median of 11.2 years, 1258 were included in the aspirin group (951 enteric-coated, 208 buffered, 99 unknown) and 1277 were included in the no-aspirin group. The cumulative incidence of upper gastrointestinal symptoms or bleeding was higher in the aspirin group than the no-aspirin group (8.8% vs. 5.7% at 18 years; p < 0.0001). The increased risk in the aspirin group was prominent within 3 years, and the hazard ratio (HR) [95% confidence interval (CI)] of the aspirin group was 7.10 [3.21-15.7], but attenuated beyond 3 years (HR 1.20 [0.76-1.89]). In 1159 patients in the aspirin group, the cumulative incidence was lower in the enteric-coated than in the buffered aspirin groups (2.9% vs. 7.3%; p = 0.003) within 3 years, and the adjusted HR of enteric-coated aspirin was 0.38 [0.20-0.72] compared with the buffered aspirin group. CONCLUSION: The upper gastrointestinal symptoms or bleeding of low-dose aspirin within 3 years, and the aspirin formulations, were relevant for decision making of initiation and continuation of low-dose aspirin for primary prevention.

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.

A Medical Claims Database Study of Factors Associated with Medication Adherence and Treatment Persistence in Patients Receiving PCSK9 Monoclonal Antibodies.

AIM: To investigate medication adherence and treatment persistence in patients receiving proprotein convertase subtilisin/kexin type 9 (PCSK9) monoclonal antibodies (mAbs) in Japan. METHODS: Using an anonymized claims database from January 2015 to December 2021, data on adult patients at high risk for atherosclerotic cardiovascular disease or with a history of coronary artery disease (CAD) who had at least 1 prescription for PCSK9-mAbs were retrieved. RESULTS: In total, 276 patients were analyzed. The cumulative treatment persistence rate after 1 year was 67.0%. A multivariate analysis revealed that better adherence to oral low-density lipoprotein cholesterol (LDL-C)-lowering therapy in the year before starting PCSK9-mAbs (adjusted odds ratio [OR] 2.16) and a history of CAD for secondary prevention (adjusted OR 2.44) were associated with better adherence to PCSK9-mAbs in the first year. Better adherence to oral LDL-C-lowering therapy in the year before starting PCSK9-mAbs (adjusted OR 2.32) and a history of CAD for secondary prevention (adjusted OR 3.03) were also associated with a lower rate of discontinuation of PCSK9-mAbs. Age, sex, comorbidity, number of tablets taken daily (all medications), and number of hospital or clinic visits in the year prior to starting PCSK9-mAbs did not affect the persistence rate or adherence to PCSK9-mAbs in the multivariate analyses. CONCLUSION: Better adherence to oral LDL-C-lowering therapy and secondary prevention were identified as factors associated with better medication adherence and treatment persistence in patients receiving PCSK9-mAbs within the first year.

Complete detection of FR1 to FR3 primer-based PCR patterns of immunoglobulin heavy chain rearrangement in the BIOMED-2 protocol is associated with poor prognosis in patients with diffuse large B-cell lymphoma.

Somatic hypermutations (SHMs) in the variable region (VH) of the immunoglobulin heavy chain (IgH) gene are common in diffuse large B-cell lymphoma (DLBCL). Recently, IgH VH SHMs have become known as immunogenic neoantigens, but few studies have evaluated the prognostic impact of the frequency of VH SHMs in DLBCL. The BIOMED-2 protocol is the gold standard polymerase chain reaction (PCR) for clonality analysis in lymphoid malignancies, but can produce false negatives due to the presence of IgH VH SHMs. To overcome this problem, three primer sets were designed for the three framework regions (FR1, FR2, and FR3). We evaluated the predictive value of this PCR pattern in patients with DLBCL. To evaluate the prognostic impact of complete detection of the clonal amplifications (VHFR1-JH, VHFR2-JH, and VHFR3-JH) in the BIOMED-2 protocol, we retrospectively analyzed 301 DLBCL patients who were initially treated with anthracycline-based immunochemotherapy. Complete detection of the FR1 to FR3 primer-based IgH VH PCR patterns in the BIOMED-2 protocol was associated with low frequency of VH SHMs (p < 0.001). Patients who were positive for all these three PCRs (n = 79) were significantly associated with shorter 5-year overall survival (OS; 54.2% vs. 73.2%; p = 0.002) and progression-free survival (PFS; 34.3% vs. 59.3%; p < 0.001) compared to patients with other PCR patterns (n = 202). Specifically, the successful FR3-JH detection was associated with significantly worse OS (p < 0.001) and PFS (p < 0.001). PCR patterns of complete IgH rearrangement using the BIOMED-2 protocol are clinically meaningful indicators for prognostic stratification of DLBCL patients.

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.

Lower Eyelid Merkel Cell Carcinoma in a Non-Immunocompromised Young Female: A Case Report.

Introduction: Merkel cell carcinoma (MCC) is a rare neuroendocrine skin tumor associated with Merkel cell polyomavirus and ultraviolet light exposure. MCC typically affects older individuals, and it also influences young patients with immunosuppressive conditions. We report a case of lower eyelid MCC in a non-immunocompromised 37-year-old woman. Case Presentation: A 37-year-old woman presenting with suspected MCC on her right lower eyelid was referred to our hospital for further resection. The patient underwent wide excision with clear margins followed by reconstruction and radiation therapy. The patient has shown no signs of recurrence after 5 months of follow-up. Conclusion: MCC needs to be considered as a possible diagnosis when examining an eyelid tumor in a young patient.

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.

Cerebrovascular Disease Detected on Preprocedural Computed Tomography in Patients With Severe Aortic Stenosis Undergoing Aortic Valve Replacement.

BACKGROUND: There is a scarcity of data on the prevalence and clinical impact of cerebrovascular disease detected on preprocedural computed tomography (CT) before aortic valve replacement (AVR) in patients with severe aortic stenosis. METHODS AND RESULTS: Among patients with severe aortic stenosis undergoing AVR, the authors compared clinical outcomes between patients with and without cerebrovascular disease detected on preprocedural CT, which was defined as chronic brain infarction or hemorrhage. The primary outcome measure in this study was a composite of all-cause death or stroke. Among 567 study patients, 200 patients (35.3%) had cerebrovascular disease on preprocedural CT. Among 200 patients with cerebrovascular disease on preprocedural CT, only 28.5% of patients had a clinical history of symptomatic stroke. The cumulative 3-year incidence of death or stroke was higher in patients with cerebrovascular disease on preprocedural CT than in those without cerebrovascular disease on preprocedural CT (40.7% versus 24.1%, log-rank P<0.001). After adjusting for confounders, the higher risk of patients with cerebrovascular disease on preprocedural CT relative to those without remained significant for death or stroke (hazard ratio [HR], 1.42 [95% CI, 1.02-1.98]; P=0.04). Among 200 patients with cerebrovascular disease on preprocedural CT, patients with prior symptomatic stroke compared with those without were not associated with higher adjusted risk for death or stroke (HR, 1.18 [95% CI, 0.72-1.94]; P=0.52). CONCLUSIONS: Among patients with severe aortic stenosis undergoing AVR, a substantial proportion had cerebrovascular disease on preprocedural CT, with a clinical history of symptomatic stroke in one-fourth of patients. Regardless of history of symptomatic stroke, patients with cerebrovascular disease on preprocedural CT had worse clinical outcomes compared with those without cerebrovascular disease on preprocedural CT.

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.

Aspirin-Free Strategy for Percutaneous Coronary Intervention in Patients With Oral Anticoagulation: Prespecified Subgroup Analysis From the STOPDAPT-3 Trial.

BACKGROUND: The effects of aspirin-free strategy on bleeding and cardiovascular events in patients undergoing percutaneous coronary intervention with oral anticoagulation (OAC) have not been fully elucidated. METHODS AND RESULTS: We conducted the prespecified subgroup analysis based on the use of OAC, including vitamin K antagonist and direct oral anticoagulants, within 7 days before percutaneous coronary intervention in the STOPDAPT-3 (Short and Optimal Duration of Dual Antiplatelet Therapy-3) trial, which randomly compared prasugrel monotherapy (2984 patients) to dual antiplatelet therapy (DAPT) with prasugrel and aspirin (2982 patients) in patients with acute coronary syndrome or high bleeding risk. The coprimary end points were major bleeding events (Bleeding Academic Research Consortium types 3 or 5) and cardiovascular events (a composite of cardiovascular death, myocardial infarction, definite stent thrombosis, or ischemic stroke) at 1 month. Among 5966 study patients, there were 530 patients (8.9%) with OAC (no aspirin: N=248, and DAPT: N=282) and 5436 patients (91.1%) without OAC (no aspirin: N=2736, and DAPT: N=2700). Regardless of the use of OAC, the effects of no aspirin compared with DAPT were not significant for the bleeding end point (OAC: 4.45% and 4.27%, hazard ratio [HR], 1.04 [95% CI, 0.46-2.35]; no-OAC: 4.47% and 4.75%, HR, 0.94 [95% CI, 0.73-1.20]; P for interaction=0.82), and for the cardiovascular end point (OAC: 4.84% and 3.20%, HR, 1.53 [95% CI, 0.64-3.62]; no-OAC: 4.06% and 3.74%, HR, 1.09 [95% CI 0.83-1.42]; P for interaction =0.46). CONCLUSIONS: The no-aspirin strategy compared with the DAPT strategy failed to reduce major bleeding events irrespective of the use of OAC. There was a numerical excess risk of the no-aspirin strategy relative to the DAPT strategy for cardiovascular events in patients with OAC.

Temporal Changes in Long-Term Outcomes of Venous Thromboembolism From the Warfarin Era to the Direct Oral Anticoagulant Era.

BACKGROUND: There have been limited data on the changes in clinical outcomes after the introduction of direct oral anticoagulants (DOACs) for venous thromboembolism (VTE) in real clinical practice. We evaluated the changes in management strategies and long-term outcomes from the warfarin era to the DOAC era. METHODS AND RESULTS: We compared the 2 series of multicenter COMMAND VTE (Contemporary Management and Outcomes in Patients With Venous Thromboembolism) registries in Japan enrolling consecutive patients with acute symptomatic VTE: Registry 1: 3027 patients in the warfarin era (2010-2014) and Registry 2: 5197 patients in the DOAC era (2015-2020). The prevalence of DOAC use increased more in Registry 2 than in the Registry 1 (Registry 1: 2.6% versus Registry 2: 79%, P<0.001). The cumulative 5-year incidence of recurrent VTE was significantly lower in Registry 2 than in Registry 1 (10.5% versus 9.5%, P=0.02), and the risk reduction of recurrent VTE in Registry 2 remained significant even after adjusting the confounders (hazard ratio [HR], 0.78 [95% CI, 0.65-0.93]; P=0.005). The cumulative 5-year incidence of major bleeding was not significantly different between the 2 registries (12.1% versus 13.7%, P=0.26), and the risk of major bleeding between the 2 registries was not significantly different even after adjusting the confounders (HR, 1.04 [95% CI, 0.89-1.21]; P=0.63). CONCLUSIONS: Along with the shift from warfarin to DOACs, there was a lower risk of recurrent VTE in the DOAC era than in the warfarin era, whereas there was no apparent change in the risk of major bleeding, which might still be an unmet need even in the DOAC era.
