Anticoagulation therapy is prescribed for the prevention of recurrence in patients with venous thromboembolism, which could be temporarily interrupted during invasive procedures. The COMMAND VTE Registry is a multicenter registry enrolling 3027 consecutive patients with acute symptomatic VTE in Japan between January 2010 and August 2014. We identified patients who underwent invasive procedures during the entire follow-up period and evaluated periprocedural managements and clinical outcomes at 30 days after invasive procedures.

Background: Patients with cancer-associated venous thromboembolism (VTE) are at high risk for recurrent VTE and are recommended to receive prolonged anticoagulation therapy if they are at a low risk for bleeding. However, there are no established risk factors for bleeding during anticoagulation therapy.

Background: There is a paucity of data comparing the long-term outcomes after inferior vena cava (IVC) filters placement for patients with acute venous thromboembolism (VTE) between those with and without active cancer.

Methods: In the COMMAND VTE Registry, we evaluated the effects of IVC filter use on the long-term clinical outcomes stratified by the presence and absence of active cancer.

Results: Among 2,626 patients with acute symptomatic VTE, there were 604 patients with active cancer, and 2022 patients without active cancer.

Article Synopsis
  • A study analyzed the effects of high-dose statins on cardiovascular outcomes in 1,110 Japanese patients recovering from ST-elevation myocardial infarction (STEMI) between 2011 and 2017.
  • While patients on high-dose statins had higher low-density lipoprotein (LDL) cholesterol levels upon admission, these levels were similar to those on non-high-dose statins by follow-up.
  • The results showed that patients on high-dose statins had significantly lower 2-year incidences of severe cardiovascular events, indicating improved outcomes mainly by reducing the need for revascularization of new lesions.

There are uncertainties on the influence of the days of diagnosis in a week (weekends versus weekdays) on clinical outcomes in patients with acute venous thromboembolism (VTE), including pulmonary embolism (PE) and deep vein thrombosis (DVT). The COMMAND VTE registry is a multicenter cohort study enrolling 3027 consecutive patients with acute symptomatic VTE. The current study population consisted of 337 patients diagnosed on weekends and 2690 patients diagnosed on weekdays.

Background: The Academic Research Consortium for High Bleeding Risk (ARC-HBR) criteria have been suggested as the standard definition of HBR. However, the prevalence of individual criteria and their prognostic value for long-term bleeding events after percutaneous coronary intervention are scarcely studied.

Methods and results: The study population comprised 1,193 patients treated with everolimus-eluting stents between 2010 and 2011.

Introduction: The external validation of the modified Ottawa score to predict the risk of recurrence in patients with cancer-associated venous thromboembolism (VTE) has not yet been firmly established. The present study aimed to evaluate the utility and limitations of the modified Ottawa score in the risk stratification of recurrent VTE in patients with cancer-associated VTE.

Introduction: Patients with renal dysfunction are at high risk for developing venous thromboembolism (VTE). However, the impact of renal dysfunction on recurrent VTE remains to be clarified. We assessed the relationship between estimated glomerular filtration rate (eGFR) at diagnosis and long-term clinical outcomes in VTE patients.

Background: The recently proposed VTE-BLEED score to predict the risk of major bleeding in patients with venous thromboembolisms (VTEs) on prolonged anticoagulation therapy was validated externally in randomized controlled trials and in a selected cohort, but not applied in non-selective cohorts.

Objectives: The present study aimed to evaluate the generalizability of the VTE-BLEED score in a non-selective cohort.

Patients/methods: The COMMAND VTE Registry is a multicenter retrospective registry enrolling consecutive patients with acute symptomatic VTEs among 29 centers in Japan.

Statins, which are considered as essential for primary and secondary prevention of atherosclerotic diseases, were also reported to reduce first venous thromboembolism (VTE). However, the effect of statins on VTE recurrence remains conflicting. We aimed to examine the association between statin use and VTE recurrence in a large observational study in Japan.

Introduction: Pulmonary embolism (PE) and deep vein thrombosis (DVT) can be considered as one clinical entity, venous thromboembolism (VTE). However, the potential differences between PE and DVT might have to be taken into consideration for the decision-making of the optimal treatment strategies.

Background: The simplified Pulmonary Embolism Severity Index (sPESI) score is a practical score for identification of patients with low-risk pulmonary embolism (PE), although it has not been applied in patients with active cancer. The current study aimed to evaluate the usefulness of the sPESI score in patients with PE and active cancer.

The relationship between D-dimer level at diagnosis and long-term clinical outcomes has not been fully evaluated in venous thromboembolism (VTE). The COMMAND VTE Registry is a multicenter registry enrolling consecutive acute symptomatic VTE patients in Japan. Patients with available D-dimer levels at diagnosis (N = 2852) were divided into 4 groups according to the D-dimer levels; Quartile 1 (0.

Studies on the outcomes of de novo three-vessel coronary artery disease (3VD) are limited. This study evaluated the outcomes after coronary revascularization in patients with 3VD treated by percutaneous coronary intervention (PCI) using second-generation drug-eluting stents (2ndDES) in comparison with coronary artery bypass grafting (CABG). We analyzed 853 patients undergoing either PCI or CABG for 3VD between 2010 and 2014.

There is still uncertainty about the optimal usage of thrombolysis for acute pulmonary embolisms (PEs), leading to a widely varying usage in the real world. The COMMAND VTE Registry is a multicenter retrospective registry enrolling consecutive patients with acute symptomatic venous thromboembolisms (VTEs) in Japan. The present study population consisted of 1549 patients with PEs treated with tissue plasminogen activator (t-PA) thrombolysis (N = 180, 12%) or without thrombolysis (N = 1369).
