2019 ESC Guidelines for the diagnosis and management of acute pulmonary embolism developed in collaboration with the European Respiratory Society (ERS)
Guidelines summarize and evaluate available evidence with the aim of assisting health professionals in proposing the best management strategies for an individual patient with a given condition. Guidelines and their recommendations should facilitate decision making of health professionals in their daily practice. However, the final decisions concerning an individual patient must be made by the responsible health professional(s) in consultation with the patient and caregiver as appropriate.
Validation of a Model for Identification of Patients at Intermediate to High Risk for Complications Associated With Acute Symptomatic Pulmonary Embolism
For patients with acute symptomatic pulmonary embolism (PE), the Bova score classifies their risk for PE-related complications within 30 days after diagnosis. The original Bova score was derived from 2,874 normotensive patients with acute PE who participated in one of six prospective PE studies.We retrospectively assessed the validity of the Bova risk model in normotensive patients with acute PE diagnosed in an academic urban ED. Two clinician investigators used baseline data for the model's four prognostic variables to stratify patients into the three Bova risk stages (I-III) for 30-day PE-related complications. Intraclass correlation coefficient (ICC) and the κ statistic were used to asse…

Identification of intermediate-risk patients with acute symptomatic pulmonary embolism
The identification of normotensive patients with acute pulmonary embolism (PE) at high risk of adverse PE-related clinical events (i.e. intermediate-risk group) is a major challenge. We combined individual patient data from six studies involving 2874 normotensive patients with PE. We developed a prognostic model for intermediate-risk PE based on the clinical presentation and the assessment of right ventricular dysfunction and myocardial injury. We used a composite of PE-related death, haemodynamic collapse or recurrent PE within 30 days of follow-up as the main outcome measure. The primary outcome occurred in 198 (6.9%) patients. Predictors of complications included systolic blood pressure …
Edoxaban versus warfarin for the treatment of symptomatic venous thromboembolism
BackgroundWhether the oral factor Xa inhibitor edoxaban can be an alternative to warfarin in patients with venous thromboembolism is unclear. MethodsIn a randomized, double-blind, noninferiority study, we randomly assigned patients with acute venous thromboembolism, who had initially received heparin, to receive edoxaban at a dose of 60 mg once daily, or 30 mg once daily (e.g., in the case of patients with creatinine clearance of 30 to 50 ml per minute or a body weight below 60 kg), or to receive warfarin. Patients received the study drug for 3 to 12 months. The primary efficacy outcome was recurrent symptomatic venous thromboembolism. The principal safety outcome was major or clinically re…
The incidence of heparin-induced thrombocytopenia in medical patients treated with low-molecular-weight heparin: a prospective cohort study.
AbstractIn contrast with extensive documentation in patients treated with unfractionated heparin (UFH), the incidence of heparin-induced thrombocytopenia (HIT) in medical patients receiving low-molecular-weight heparin (LMWH) is less well defined. In a prospective cohort study, the platelet count was monitored in 1754 consecutive patients referred to 17 medical centers and treated with LMWH for prophylaxis or treatment of thromboembolic disorders. The diagnosis of HIT was accepted in case of a platelet drop of at least 50%, the absence of obvious explanations for thrombocytopenia, and the demonstration of heparin-dependent IgG antibodies. HIT developed in 14 patients (0.80%; 95% CI, 0.43%-1…
Aspirin After Oral Anticoagulants for Prevention of Recurrence in Patients with Unprovoked Venous Thromboembolism. the Warfasa STUDY
Abstract Abstract 543 Background A recurrence occurs in 15–20% of patients with unprovoked venous thromboembolism (VTE) in the two years after the withdrawal of oral anticoagulant treatment. Extending anticoagulant treatment is effective but associated with increased bleeding risk. We assessed the efficacy and safety of aspirin for the prevention of VTE recurrence after a conventional course of oral anticoagulation. Methods Warfasa was an investigator-initiated double-blind randomized placebo-controlled event-driven study. Patients with a first-ever unprovoked VTE who had completed 6–12 months of oral anticoagulant treatment were randomized to receive aspirin, 100 mg daily, or placebo for a…
Long-term risk of recurrent venous thromboembolism among patients receiving extended oral anticoagulant therapy for first unprovoked venous thromboembolism:A systematic review and meta-analysis
Background: The long-term risk for recurrent venous thromboembolism (VTE) during extended anticoagulation for a first unprovoked VTE is uncertain. Objectives: To determine the incidence of recurrent VTE during extended anticoagulation of up to 5 years in patients with a first unprovoked VTE. Methods: MEDLINE, EMBASE, and the Cochrane CENTRAL were searched to identify randomized trials and prospective cohort studies reporting recurrent VTE among patients with a first unprovoked VTE who were to receive anticoagulation for a minimum of six additional months after completing ≥3 months of initial treatment. Unpublished data on number of recurrent VTE and person-years, obtained from authors of in…
Usefulness of Thrombophilia Testing in Venous Thromboembolic Disease
Information on thrombophilia risk factors for patients with upper extremity deep vein thrombosis (UEDVT) is limited. The genetic, acquired, and coagulation risk factors of an acute episode of lower EDVT (LEDVT) or UEDVT, either isolated or associated with pulmonary embolism (PE), were studied.A total of 4503 patients participated in a thrombophilia study. Odds ratio (OR) and 95% confidence intervals (CIs) were calculated.Mean age of the participants was 55 ± 19 years. The risk of LEDVT or UEDVT, isolated or associated with PE, was calculated according to thrombophilia factors. We found association between LEDVT and factor V Leiden ([FVL]; OR: 1.8; 95% CI 1.4-2.4) and resistance to activated…
Long-term risk for major bleeding during extended oral anticoagulant therapy for first unprovoked venous thromboembolism: A systematic review and meta-analysis
BACKGROUND The long-term risk for major bleeding in patients receiving extended (beyond the initial 3 to 6 months) anticoagulant therapy for a first unprovoked venous thromboembolism (VTE) is uncertain. PURPOSE To determine the incidence of major bleeding during extended anticoagulation of up to 5 years among patients with a first unprovoked VTE, overall, and in clinically important subgroups. DATA SOURCES MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials from inception to 23 July 2021. STUDY SELECTION Randomized controlled trials (RCTs) and prospective cohort studies reporting major bleeding among patients with a first unprovoked VTE who were to receive oral anticoagu…
