Other prognostic markers have been proposed for risk stratification, including B-type natriuretic peptide and N-terminal pro-b-type natriuretic peptide (NT-proBNP). Comparison of guideline recommendations from ASH*, CHEST†, and ESC‡ for diagnosis and treatment of pulmonary embolism. We focused our search on systematic reviews and meta-analyses judged to be of medium or high quality by the AMSTAR tool or as of acceptable quality by the SIGN-50 tool.2627 When multiple systematic reviews or meta-analyses covered the same topic, we chose the study with the best methodological quality; when studies had similar quality, we chose the most recent. RCTs have compared outpatient versus inpatient management of pulmonary embolism and found no difference in outcomes in selected patients. This class of drugs includes direct Xa inhibitors (apixaban, edoxaban, rivaroxaban) and a direct thrombin inhibitor (dabigatran). Family history of venous thromboembolism portends higher risk,55 particularly when the venous thromboembolism is unprovoked or the patient is under 50 years of age.56 Despite this, considerable controversy remains around the value of inherited thrombophilia testing (factor V Leiden mutation, prothrombin gene mutation, protein C deficiency, protein S deficiency, and antithrombin deficiency), as evidence suggests that the presence of thrombophilia does not alter management.56 Furthermore, thrombophilia testing does not identify all inherited causes of venous thromboembolism.5758 This is illustrated by the observation that only 30% of people with a family history of a first degree relative with venous thromboembolism will have a positive thrombophilia screen.59. All authors reviewed the full manuscript and contributed to its content and references. If blood thinners are not appropriate, a temporary vena cava filter may be used. VKAs may be used if LMWH or DOACs are unavailable or contraindicated, such as with severe renal impairment or drug-drug interactions. Apixaban at both doses resulted in fewer recurrent primary outcome events compared with placebo (hazard ratio 0.36 (0.25 to 0.53) for apixaban 5 mg versus placebo and 0.33 (0.22 to 0.48) for apixaban 2.5 mg versus placebo). Prognosis depends upon degree of cardiopulmonary compromise and patient response to therapy. Further studies are needed to determine the efficacy of DOACs in lower risk antiphospholipid syndrome (for example, non-lupus anticoagulant, IgM class, and low titer antibodies) and to identify subpopulations of patients with antiphospholipid syndrome in whom DOACs might be acceptable (for example, non-arterial thrombotic history). Caution should be applied in making indirect comparisons of the major bleeding rate in CARAVAGGIO with those in other trials, as important differences in enrolled patients exist. 2010. In cancer associated pulmonary embolism, cancer is a major persistent risk factor and the need for extended anticoagulation therapy, beyond six months, is suggested for patients with active cancer (metastatic disease) or receiving chemotherapy.112Box 3 shows the options for extended therapy. Computed tomography pulmonary angiography is the gold standard for PTE diagnosis in humans. Risk stratification has been used to identify patients with a low short term mortality risk to select for outpatient management. In the meantime, patients’ preferences and regular evaluation of bleeding risks should be incorporated into decisions about extended therapy. Definition of PE Pulmonary embolism—mechanical obstruction of the pulmonary vessels. Determination of clinically relevant drug interactions is complex in patients with cancer, as they are often treated with many anticancer therapies that may compete for a common metabolic pathway.

Both risk prediction scores were able to differentiate between low and high risk of 30 day mortality in patients with pulmonary embolism.91 The PESI and the Hestia criteria have been used in randomized studies to select patients with low risk pulmonary embolism suited to outpatient care (discussed below).9293 Biomarkers have also been studied. These observations led the investigators to speculate that general deconditioning may be the cause of the patient’s reported dyspnea and exercise limitation. Risk factors for development of CTEPH after acute pulmonary embolism include diagnostic delay, high thrombus load, recurrent symptomatic pulmonary embolism, pulmonary hypertension or right ventricular dysfunction at baseline, and failure to achieve thrombus resolution.148152153 A diagnosis of CTEPH is confirmed by showing a mean pulmonary artery pressure above 25 mm Hg combined with thrombotic pulmonary vascular obstructions. Parenteral anticoagulation with low molecular weight heparin (LMWH), fondaparinux, or intravenous unfractionated heparin is typically used in patients admitted to hospital for initial management of pulmonary embolism. NLM The EINSTEIN CHOICE RCT compared rivaroxaban 20 mg daily and rivaroxaban 10 mg daily against aspirin 100 mg daily for extended treatment of venous thromboembolism in 3400 participants who completed at least six to 12 months of anticoagulation for acute venous thromboembolism.145 The trial was not sufficiently powered to compare the different doses of rivaroxaban with each other. Clinical probability scores can be used to assign a pre-test probability for pulmonary embolism.

The most notable finding of this trial was that no difference in overall death was seen between the two groups, perhaps because patients randomized to the heparin only group successfully received rescue thrombolysis on development of hemodynamic decompensation.
