Aims To systematically assess late outcomes of acute pulmonary embolism (PE) and to investigate the clinical implications of post-PE impairment (PPEI) fulfilling prospectively defined criteria. Methods and results A prospective multicentre observational cohort study was conducted in 17 large-volume centres across Germany. Adult consecutive patients with confirmed acute symptomatic PE were followed with a standardized assessment plan and pre-defined visits at 3, 12, and 24 months. The co-primary outcomes were (i) diagnosis of chronic thromboembolic pulmonary hypertension (CTEPH), and (ii) PPEI, a combination of persistent or worsening clinical, functional, biochemical, and imaging parameters during follow-up. A total of 1017 patients (45% women, median age 64 years) were included in the primary analysis. They were followed for a median duration of 732 days after PE diagnosis. The CTEPH was diagnosed in 16 (1.6%) patients, after a median of 129 days; the estimated 2-year cumulative incidence was 2.3% (1.2–4.4%). Overall, 880 patients were evaluable for PPEI; the 2-year cumulative incidence was 16.0% (95% confidence interval 12.8–20.8%). The PPEI helped to identify 15 of the 16 patients diagnosed with CTEPH during follow-up (hazard ratio for CTEPH vs. no CTEPH 393; 95% confidence interval 73–2119). Patients with PPEI had a higher risk of re-hospitalization and death as well as worse quality of life compared with those without PPEI. Conclusion In this prospective study, the cumulative 2-year incidence of CTEPH was 2.3%, but PPEI diagnosed by standardized criteria was frequent. Our findings support systematic follow-up of patients after acute PE and may help to optimize guideline recommendations and algorithms for post-PE care. [ABSTRACT FROM AUTHOR]

Background: Few data are available on the long-term course and predictors of quality of life (QoL) following acute pulmonary embolism (PE).Research Question: What are the kinetics and determinants of disease-specific and generic health-related QoL 3 and 12 months following an acute PE?Study Design and Methods: The Follow-up after Acute Pulmonary Embolism (FOCUS) study prospectively followed up consecutive adult patients with objectively diagnosed PE. Patients were considered for study who completed the Pulmonary Embolism Quality of Life (PEmb-QoL) questionnaire at predefined visits 3 and 12 months following PE. The course of disease-specific QoL as assessed using the PEmb-QoL and the impact of baseline characteristics using multivariable mixed effects linear regression were studied; also assessed was the course of generic QoL as evaluated by using the EuroQoL Group 5-Dimension 5-Level utility index and the EuroQoL Visual Analog Scale.Results: In 620 patients (44% women; median age, 62 years), overall disease-specific QoL improved from 3 to 12 months, with a decrease in the median PEmb-QoL score from 19.4% to 13.0% and a mean individual change of -4.3% (95% CI, -3.2 to -5.5). Female sex, cardiopulmonary disease, and higher BMI were associated with worse QoL at both 3 and 12 months. Over time, the association with BMI became weaker, whereas older age and previous VTE were associated with worsening QoL. Generic QoL also improved: the mean ± SD EuroQoL Group 5-Dimension 5-Level utility index increased from 0.85 ± 0.22 to 0.87 ± 0.20 and the visual analog scale from 72.9 ± 18.8 to 74.4 ± 19.1.Interpretation: In a large cohort of survivors of acute PE, the change of QoL was quantified between months 3 and 12 following diagnosis, and factors independently associated with lower QoL and slower recovery of QoL were identified. This information may facilitate the planning and interpretation of clinical trials assessing QoL and help guide patient management.Clinical Trial Registration: German Clinical Trials Registry (Deutsches Register Klinischer Studien: www.drks.de); No.: DRKS00005939.

Introduction: Chronic thromboembolic pulmonary hypertension (CTEPH) is often diagnosed late in acute pulmonary embolism survivors: more efficient testing to expedite diagnosis may considerably improve patient outcomes. The InShape II algorithm safely rules out CTEPH (failure rate 0.29%) while requiring echocardiography in only 19% of patients but may be improved by adding detailed reading of the computed tomography pulmonary angiography diagnosing the index pulmonary embolism., Methods: We evaluated 12 new algorithms, incorporating the CTEPH prediction score, ECG reading, N‑terminal pro-brain natriuretic peptide levels and dedicated computed tomography pulmonary angiography reading, in the international InShape II cohort (n=341) and part of the German FOCUS cohort (n=171). Evaluation criteria included failure rate, defined as the incidence of confirmed CTEPH in pulmonary embolism patients in whom echocardiography was deemed unnecessary by the algorithm, and the overall net reclassification index compared to the InShape II algorithm., Results: The algorithm starting with computed tomography pulmonary angiography reading of the index pulmonary embolism for six signs of CTEPH, followed by ECG/N-terminal pro-brain natriuretic peptide level assessment and echocardiography resulted in the most beneficial change compared to InShape II, with a need for echocardiography in 20% (+5%), a failure rate of 0% and a net reclassification index of +3.5%, reflecting improved performance over the InShape II algorithm. In the FOCUS cohort, this approach lowered echocardiography need to 24% (-6%) and missed no CTEPH cases, with a net reclassification index of +6.0%., Conclusion: Dedicated computed tomography pulmonary angiography reading of the index pulmonary embolism improved the performance of the InShape II algorithm and may improve the selection of pulmonary embolism survivors who require echocardiography to rule out CTEPH., Competing Interests: Conflict of interest: S.

Aims: Data on the early course and use of systemic thrombolysis in pregnant women with pulmonary embolism associated or not with haemodynamic failure are scarce. We investigated these aspects using the information from the German Nationwide Inpatient Registry (years 2005-2016)., Methods and Results: In Germany, all diagnoses referring to hospitalized patients are coded according to the International Classification of Diseases and Related Health Problems, 10th Revision with German Modification. We analysed data of pregnant women aged 18-50 years for whom the following diagnoses were recorded during hospitalization: (i) pulmonary embolism (I26) during pregnancy or peripartum (O09) or (ii) obstetric thromboembolism (O88.2). Haemodynamic failure at any time during the in-hospital stay was defined as need for cardiopulmonary resuscitation (OPS code 8-77) or the presence of shock (International Classification of Diseases and Related Health Problems, 10th Revision with German Modification code R57). The primary study outcome was in-hospital death. A total of 8 271 327 births were registered in Germany from 2005 to 2016. During this 12 year time period, there were 1846 hospitalizations for pregnancy-associated pulmonary embolism in patients aged 18-50, corresponding to 2.2 [95% confidence interval (CI): 2.1-2.3] cases every 10 000 births and 0.2% of all hospitalizations for pulmonary embolism in Germany. The median age was 31 years, and the median length of hospitalization was 8 days. A total of 63 deaths were reported, corresponding to an overall in-hospital fatality rate of 3.4% (95% CI: 2.7-4.4) and a pulmonary embolism-related mortality rate of 0.8 (95% CI: 0.6-1.0) per 100 000 (live) births per year. Pulmonary embolism-related deaths in hospitalized pregnant women represented 14% of all maternal deaths recorded in Germany between 2005 and 2016. A total of 135 (7.3%) women had haemodynamic failure, of whom 51 (37.8%) received systemic thrombolysis and 50 (37.0%) died., Conclusions: Pulmonary embolism-related fatality remains substantial in pregnant women with pulmonary embolism and represents a frequent cause of maternal mortality. The use of systemic thrombolysis was reported in one third of pregnant women with pulmonary embolism and haemodynamic failure. Better preventive and management strategies should be urgently implemented in this vulnerable patient group., (© 2020 The Authors.

Background: While the importance of patients' quality of life (QoL) in chronic cardiac or pulmonary disease is uncontroversial, the burden of an acute pulmonary embolism (PE) on QoL has received little attention thus far., Objectives: We aimed to validate the German PEmb-QoL questionnaire, identify associations between QoL and clinical/functional parameters, and investigate the prognostic relevance of QoL for long-term survival in survivors of an acute PE episode., Patients/methods: Patients were invited for a clinical follow-up visit including assessment of QoL using the German PEmb-QoL questionnaire 6 months after an objectively confirmed PE at a single center. Internal consistency reliability, construct-related validity, and regressions between PEmb-QoL and clinical patient-characteristics were assessed using standard scale construction techniques., Results: Overall, 101 patients [median age, 69 ([interquartile range] IQR 57-75) years; women, 48.5%] were examined 208 (IQR 185-242) days after PE. Internal consistency reliability and construct-related validity of the PEmb-QoL questionnaire were acceptable. As many as 47.0% of patients reported dyspnea, 27.5% had right ventricular (RV) dysfunction on transthoracic echocardiography (TTE), and 25.3% were diagnosed with post-PE impairment (PPEI) at 6-month follow-up. Furthermore, 15.9% of patients were diagnosed with depression 6 months after an acute PE. The QoL was affected by dyspnea, preexisting pulmonary disease, and PPEI, and a reduced QoL was associated with an increased risk for long-term mortality after an observation period of 3.6 years., Conclusions: The German PEmb-QoL questionnaire is a reliable instrument for assessing QoL 6 months after PE. The QoL was affected by dyspnea, preexisting pulmonary disease, and PPEI and was associated with long-term mortality., (© 2019 The Authors.

Patients with intermediate-risk pulmonary embolism (PE) may, depending on the method and cut-off values used for definition, account for up to 60% of all patients with PE and have an 8% or higher risk of short-term adverse outcome. Although four non-vitamin K-dependent direct oral anticoagulants (NOACs) have been approved for the treatment of venous thromboembolism, their safety and efficacy as well as the optimal anticoagulation regimen using these drugs have not been systematically investigated in intermediate-risk PE. Moreover, it remains unknown how many patients with intermediate-high-risk and intermediate-low-risk PE were included in most of the phase III NOAC trials. The ongoing Pulmonary Embolism International Thrombolysis 2 (PEITHO-2) study is a prospective, multicentre, multinational, single-arm trial investigating whether treatment of acute intermediate-risk PE with parenteral heparin anticoagulation over the first 72 hours, followed by the direct oral thrombin inhibitor dabigatran over 6 months, is effective and safe. The primary efficacy outcome is recurrent symptomatic venous thromboembolism or death related to PE within the first 6 months. The primary safety outcome is major bleeding as defined by the International Society on Thrombosis and Haemostasis. Secondary outcomes include all-cause mortality, the overall duration of hospital stay (index event and repeated hospitalizations) and the temporal pattern of recovery of right ventricular function over the 6-month follow-up period. By applying and evaluating a contemporary risk-tailored treatment strategy for acute PE, PEITHO-2 will implement the recommendations of current guidelines and contribute to their further evolution., Competing Interests: Financial Support: PEITHO-2 is an independent, investigator-initiated trial. The study has an academic sponsor (University Medical Center Mainz, Germany) and is supported by public funding. In addition, the sponsor has obtained the study drug (dabigatran) and a grant from the market authorization holder of dabigatran, Boehringer Ingelheim. The authors are solely responsible for the design and conduct of the PEITHO-2 trial study, for all study analyses and for the drafting and editing of reports and publications and their final contents.
