Abstract
Pulmonary embolism remains a common and potentially deadly disease, despite advances in diagnostic imaging, treatment and prevention. Managing pulmonary embolism requires a multifactorial approach involving risk stratification, determining appropriate diagnostics and selecting individualised therapy. The first part of this article reviewed the pathophysiology, risk factors, clinical presentation, diagnostic evaluation and therapeutic management and early outpatient management of pulmonary embolism. This second part summarises pulmonary embolism in the setting of pregnancy, COVID-19, recurrent disease and chronic thromboembolic pulmonary hypertension.

Abstract
Bleeding is the most common complication of anticoagulant use. The evaluation and management of the bleeding patient is a core competency of emergency medicine. As the prevalence of patients receiving anticoagulant agents and variety of anticoagulants with different mechanisms of action, pharmacokinetics, indications, and corresponding reversal agents increase, physicians and other clinicians working in the emergency department require a current and nuanced understanding of how best to assess, treat, and reverse anticoagulated patients. In this project, we convened an expert panel to create a consensus decision tree and framework for assessment of the bleeding patient receiving an anticoagulant, as well as use of anticoagulant reversal or coagulation factor replacement, and to address controversies and gaps relevant to this topic. To support decision tree interpretation, the panel also reached agreement on key definitions of life-threatening bleeding, bleeding at a critical site, and emergency surgery or urgent invasive procedure. To reach consensus recommendations, we used a structured literature review and a modified Delphi technique by an expert panel of academic and community physicians with training in emergency medicine, cardiology, hematology, internal medicine/thrombology, pharmacology, toxicology, transfusion medicine and hemostasis, neurology, and surgery, and by other key stakeholder groups.

Impact of Prolonged Anticoagulation with Rivaroxaban on Provoked Venous Thromboembolism Recurrence: IMPROVE-VTE. Am J Med 2019; 132:498-504. [PMID: 30582894 DOI: 10.1016/j.amjmed.2018.11.040] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/20/2018] [Revised: 11/21/2018] [Accepted: 11/28/2018] [Indexed: 12/18/2022]
Abstract
BACKGROUND We sought to evaluate the real-world effectiveness and safety of prolonged anticoagulation with rivaroxaban following a provoked venous thromboembolism. METHODS Using US MarketScan claims from November 2012 to March 2017, we identified adults with ≥1 primary hospitalization or emergency department diagnosis code for venous thromboembolism, a provoking (major or minor, persistent or transient) risk factor, at least 3 months of continuous rivaroxaban treatment, and ≥12 months of continuous insurance benefits prior to their qualifying venous thromboembolism. Patients were categorized as either continuing rivaroxaban or discontinuing anticoagulation (no anticoagulation or nonaspirin antiplatelet agents but may have received aspirin) after the initial 3 months of rivaroxaban treatment (index date). Differences in baseline covariates between cohorts were adjusted for using inverse probability-of-treatment weights based on propensity scores (absolute standardized differences <0.1 achieved for all covariates after adjustment). Twelve month incidences of recurrent venous thromboembolism or major bleeding were compared between cohorts using Cox regression (according to an intention-to-treat methodology) and reported as hazard ratios (HRs) with 95% confidence intervals (CIs). RESULTS Among patients experiencing a provoked venous thromboembolism and treated with rivaroxaban for the first 3 months (N=4,990), continued rivaroxaban use beyond 3 months (median [25%, 75% range duration of additional rivaroxaban use = 3 [2, 5] months) was associated with a 44% (95% CI of 9%-66%) lower hazard of recurrent venous thromboembolism without altering major bleeding risk [HR of 0.87, 95% CI of 0.51-1.49] versus anticoagulation discontinuation (with or without aspirin use). CONCLUSIONS Our study suggests continuing rivaroxaban after the initial 3 month period was associated with a decreased risk of recurrent venous thromboembolism. The observed reduction in recurrent venous thromboembolism with prolonged rivaroxaban use was not associated with a significant change in major bleeding risk.

Abstract
INTRODUCTION Idiopathic or unprovoked venous thromboembolism is an event occurring in the absence of any apparent provoking or triggering environmental risk factors, such as surgery, trauma, and immobilization. Areas covered: Unprovoked VTE can be associated with occult cancer, but only limited, and not extensive cancer screening, may be warranted, as the rate of occult cancer is low in such patients. Routine thrombophilia testing is not currently recommended as it does not influence the management of the disease. The duration of anticoagulation for unprovoked VTE after the first three months is still debated as the disease tends to recur regardless of treatment duration. Expert commentary: Prognostic scores incorporating patient related risk factors, such as age and sex, and global markers of hypercoagulability, such as D-dimer, have been proposed for identifying high risk patients who are candidates for extended anticoagulation beyond three months. Direct oral anticoagulants, aspirin and sulodexide could be alternative to vitamin K antagonists (VKA) for long term treatment in such patients. The most up to date guidelines suggest DOACs over VKA for non-cancer VTE in the first three months and also long-term in subjects at low or moderate risk of bleeding, albeit with grade 2B strength of recommendation.

Tranexamic Acid Can Be Administered to Arthroplasty Patients Who Receive Aspirin for Venous Thromboembolic Prophylaxis. J Arthroplasty 2016; 31:1437-41. [PMID: 27026644 DOI: 10.1016/j.arth.2015.12.042] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/01/2015] [Revised: 12/21/2015] [Accepted: 12/21/2015] [Indexed: 02/01/2023] Open
Abstract
BACKGROUND Venous thromboembolism (VTE) is not uncommon after total joint arthroplasty (TJA). Various prophylactic agents have been used to minimize this complication after TJA. Numerous studies have demonstrated that acetylsalicylic acid (ASA) has equivalent efficacy to other agents in preventing VTE after TJA. However, some have expressed theoretical concern that ASA may not be an adequate VTE prophylaxis in TJA patients receiving tranexamic acid (TA), which is an antifibrinolytic agent. The purpose of the study was to assess the safety and efficacy of administering systemic TA in TJA patients who also received ASA for VTE prophylaxis. METHODS A retrospective study was conducted on 2835 consecutive patients (1678 receiving TA and 1157 not receiving TA) who underwent primary or revision TJA between January 2013 and June 2014 and also received aspirin for VTE prophylaxis. The incidence of symptomatic deep vein thrombosis and pulmonary embolism was evaluated. RESULTS Blood loss and transfusion rates were significantly lower in the TA group compared to the non-TA group (P < .0001, P = .017, respectively). The incidence of VTE, bleeding events, and wound complications was similar (P > .05) between the groups. CONCLUSION In patients undergoing TJA who receive ASA for VTE prophylaxis, TA reduces bleeding and transfusions without increasing the incidence of subsequent VTE.
