BACKGROUND: It may be possible to safely rule out pulmonary embolism (PE) in patients with low pretest probability (PTP) using a higher than standard D-dimer threshold. The YEARS criteria, which include three questions from the Wells PE score to identify low-PTP patients and a variable D-dimer threshold, was recently shown to decrease the need for imaging to rule out PE by 14% in a multicenter study in the Netherlands. However, the YEARS approach has not been studied in the United States...

BACKGROUND: Patients with COPD experience episodes of increased inflammation, so-called acute exacerbations of COPD (AE-COPD). In 30% of AE-COPD cases, no clear cause is found. Since there is well-known cross talk between inflammation and thrombosis, the objectives of this study were to determine the prevalence, embolus localization, clinical relevance, and clinical markers of pulmonary embolism (PE) in unexplained AE-COPD. METHODS: A systematic search was performed using MEDLINE and EMBASE platforms from 1974 to October 2015...

BACKGROUND: The efficacy of thrombolytic therapy in patients with submassive pulmonary embolism (PE) remains unclear. Previous meta-analyses have not separately reported the proportion of patients with submassive PE. OBJECTIVE: We assessed the effect of thrombolytic therapy on mortality, recurrent PE, clinical deterioration requiring treatment escalation and bleeding in patients with submassive PE. METHODS: The MEDLINE, EMBASE and Cochrane Library databases were searched to identify all relevant randomized controlled trials comparing adjunctive thrombolytic therapy with heparin alone as initial treatments in patients with acute submassive PE, and reported 30-day mortality or in-hospital clinical outcomes...

There is variability in guideline recommendations for assessment of the right ventricle (RV) with imaging as prognostic information after acute pulmonary embolism (PE). The objective of this study is to identify a clinical scenario for which normal CT-derived right-to-left ventricular (RV/LV) ratio is sufficient to exclude RV strain or PE-related short-term death. This retrospective cohort study included 579 consecutive subjects (08/2003-03/2010) diagnosed with acute PE with normal CT-RV/LV ratio (<0.9), 236 of whom received subsequent echocardiography...

OBJECTIVE: The purpose of this study is to assess the use of a pulmonary embolism (PE)- computer-aided detection (CADx) program in the detection of PE missed in clinical practice. MATERIALS AND METHODS: Pulmonary CT angiography (CTA) studies (n = 6769) performed between January 2009 and July 2012 were retrospectively assessed by a thoracic radiologist. In studies that were positive for PE, all prior contrast-enhanced pulmonary CTA studies were reviewed. Missed PE was deemed to have occurred if PE was not described in the final interpretation...

BACKGROUND: CT pulmonary angiography (CTPA) is considered the gold standard for the diagnosis of pulmonary embolism (PE) and is frequently performed in patients with cardiopulmonary complaints. However, indiscriminate use of CTPA results in significant exposure to ionizing radiation and contrast. We studied the accuracy of a bedside ultrasound protocol to predict the need for CTPA. METHODS: This was an observational study performed by pulmonary/critical care physicians trained in critical care ultrasonography...

BACKGROUND: This study aimed to assess the performance of two prognostic models-the European Society of Cardiology (ESC) model and the simplified Pulmonary Embolism Severity Index (sPESI)-in predicting short-term mortality in patients with pulmonary embolism (PE). METHODS: We compared the test characteristics of the ESC model and the sPESI for predicting 30-day outcomes in a cohort of 526 patients with objectively confirmed PE. The primary end point of the study was all-cause mortality...

The aim of this narrative review is to summarize for intensivists or any physicians managing "severe" pulmonary embolism (PE) the main recent advances or recommendations in the care of patients including risk stratification, diagnostic algorithm, hemodynamic management in the intensive care unit (ICU), recent data regarding the use of thrombolytic treatment and retrievable vena cava filters and finally results of direct oral anticoagulants. Thanks to the improvements achieved in the risk stratification of patients with PE, a better therapeutic approach is now recommended from diagnosis algorithm and indication to admission in ICU to indication of thrombolysis and general hemodynamic support in patients with shock...

BACKGROUND: Computed tomographic pulmonary angiography (CTPA) has simplified the diagnostic approach to patients with suspected pulmonary embolism (PE). However, PE diagnosis is still probabilistic and CTPA should be used with caution in some patient groups, such as patients with severe renal insufficiency and pregnant women. Among alternative imaging tests, lung ultrasound is the most promising technique. We aimed to systematically assess the diagnostic accuracy of lung ultrasound for PE diagnosis...

Pulmonary embolism remains a common and potentially life-threatening disease. For patients with intermediate- and high-risk pulmonary embolism, catheter-based revascularization therapy has emerged as potential alternative to systemic thrombolysis or surgical embolectomy. Ultrasound-assisted catheter-directed thrombolysis is a contemporary catheter-based technique and is the focus of the present review. Ultrasound-assisted catheter-directed thrombolysis is more effective in reversing right ventricular dysfunction and dilatation in comparison with anticoagulation alone in patients at intermediate risk...

BACKGROUND: Strategies for identifying normotensive patients with acute symptomatic PE at high risk of PE-related complications remain to be defined. METHODS: This prospective cohort study aimed to determine the role of plasma lactate levels in the risk assessment of normotensive patients with acute PE. Outcomes assessed over the 7 days after the diagnosis of PE included PE-related mortality and haemodynamic collapse, defined as need for cardiopulmonary resuscitation, systolic blood pressure <90 mm Hg for at least 15 min, need for catecholamine administration, or need for mechanical ventilation...

This study aimed to determine the effect of an evidence-based clinical decision support (CDS) algorithm on the use and yield of CT pulmonary angiography (CTPA) and on outcomes of patients evaluated in the emergency department (ED) for suspected PE. The study included 1363 consecutive patients evaluated for suspected PE in an ED during 12 months before and 12 months after initiation of CDS use. Introduction of CDS was associated with decreased CTPA use (55% vs 49%; absolute difference (AD), 6.3%; 95% CI 1...

BACKGROUND: Physicians treating acute pulmonary embolism (PE) are faced with difficult management decisions while specific guidance from recent guidelines may be absent. METHODS: Fourteen clinical dilemmas were identified by physicians and haematologists with specific interests in acute and chronic PE. Current evidence was reviewed and a practical approach suggested. RESULTS: Management dilemmas discussed include: sub-massive PE, PE following recent stroke or surgery, thrombolysis dosing and use in cardiac arrest, surgical or catheter-based therapy, failure to respond to initial thrombolysis, PE in pregnancy, right atrial thrombus, role of caval filter insertion, incidental and sub-segmental PE, differentiating acute from chronic PE, early discharge and novel oral anticoagulants...

BACKGROUND: Clinical probability assessment is combined with d-dimer testing to exclude pulmonary embolism (PE). PURPOSE: To compare the test characteristics of gestalt (a physician's unstructured estimate) and clinical decision rules for evaluating adults with suspected PE and assess the failure rate of gestalt and rules when used in combination with d-dimer testing. DATA SOURCES: Articles in MEDLINE and EMBASE in English, French, German, Italian, Spanish, or Dutch that were published between 1966 and June 2011...
