Abstract Funding Acknowledgements Type of funding sources: None. Background Extracorporeal membrane oxygenation (ECMO) is a life-saving therapy for patients with acute pulmonary embolism (PE) and concomitant cardiac arrest with the necessity of cardiopulmonary resuscitation (CPR). Little is known about the use and clinical outcome of veno-arterial (VA)-ECMO and adjunctive treatment strategies in patients with acute PE and CPR. Purpose In this context, we aimed to investigate the use of VA-ECMO alone or after systemic thrombolysis and its impact on in-hospital outcomes of patients with acute PE and CPR. Methods We analyzed data on the characteristics, treatments and in-hospital outcomes for all patients with acute PE (ICD-code I26) and CPR in Germany between the years 2005 and 2018 (source: Research Data Center (RDC) of the Federal Statistical Office and the Statistical Offices of the federal states, DRG Statistics 2005-2018, own calculations). Results Between 2005 and 2018, 1,172,354 patients with acute PE (53.5% females) were included in this analysis; of those, 77,196 (6.5%) presented with cardiac arrest and CPR. While more than one fourth of those patients were treated with systemic thrombolysis alone (n = 20,839 patients; 27.0%), a minority received a combination of thrombolysis + VA-ECMO (n = 165; 0.2%) or singular approach with VA-ECMO treatment alone (n = 588; 0.8%). The overall in-hospital mortality rate of PE patients with cardiac arrest was high with 83.8%. Non-survivors were considerable older than survivors (74 [IQR 63-81] vs. 69 [58-77]). In patients treated with VA ECMO alone the mortality rate was 71.1% and 69.7% when patients received Thrombolysis + VA-ECMO. Patients, who received thrombolysis without VA-ECMO had a higher mortality rate (83.8%). In order to investigate the impact of those different treatment strategies, a multivariate logistic regression analysis (adjusted for age, sex and comorbidities) demonstrated the lowest risk for in-hospital death in patients, who underwent the combination of Thrombolysis + VA-ECMO (OR, 0.61 [95% CI, 0.43-0.86], P = 0.004) or VA-ECMO alone (OR, 0.70 [0.58-0.84], P < 0.001) compared to patients without VA-ECMO and without thrombolysis. Use of thrombolysis alone in patients with PE and CPR lowering the risk regarding in-hospital death as well (OR, 0.95 [0.91-0.99], P = 0.013). Regarding temporal trends, the annual use of VA-ECMO increased from 0 in the year 2005 to the number of 138 in 2018 (ß 6.13 (4.62-6.76); p < 0.001) as well as for the combined treatment Thrombolysis + VA-ECMO (from 0 to 39 [ß 4.28 (3.68-4.89); p < 0.001]). Conclusion Patients with acute PE and CPR had a very high in-hospital mortality rate. Our data suggest, that VA-ECMO alone or after systemic thrombolysis should be considered as an option in this outstanding life-threatening situation to improve in-hospital outcome. Furthermore, our data highlight a marked increase in the number of PE patients treated with VA-ECMO indicating the structural health care progress between 2005 and 2018.

Background: The role of inpatient transthoracic echocardiography (TTE) in patients with acute pulmonary embolism (PE) is unclear. Although right ventricular dysfunction (RVD) predicts adverse outcomes in acute PE, there is no consensus on the optimal TTE findings for prognostication and how they influence management, particularly when CT and/or an elevated cardiac troponin already suggest RVD. Understanding current practices regarding inpatient TTE in acute PE can help direct appropriate use. Our objectives were to (i) characterize inpatient TTE use in adult patients hospitalized with acute PE, (ii) describe and compare findings of RVD by TTE, CT and troponin, and (iii) explore differences in outcomes between patients managed with or without TTE. Methods: We conducted a retrospective cohort study of adult patients hospitalized with acute PE at two academic hospitals in Hamilton, Canada between January and December 2018. Patients with suspected PE that was not objectively confirmed, or PE diagnosed prior to hospitalization were excluded. We also excluded patients who had a TTE prior to the diagnosis of PE. Chi-square tests and independent t-tests were used. P-values less than 0.05 were considered significant. Results: We identified 178 adult patients (mean age 66 ± 15 years; 42% male). Patients were admitted to internal medicine (53%), oncology (19%), surgical specialties (13%) and intensive care units (ICU, 11%). Of 146 patients, 134 (92%) had a PE involving segmental or larger vessels. TTE was conducted in 86 (48%) patients. Systemic thrombolysis was administered to 11 (6%) patients. A higher proportion of patients with an elevated troponin (66% vs. 35% p<0.001) or evidence of RV strain on CT (65% vs. 35%, p=0.001) underwent TTE compared to those without these findings. Patients admitted to the ICU more frequently underwent TTE (69% vs. 44%, p=0.012). RV size and function were normal in 49 (59%) and 53 (63%) cases, respectively. Patients with RV strain on CT were more likely to have RV enlargement (58% vs. 30%, p=0.04) and RVD (58% vs. 25%, p=0.011) on TTE. However, right ventricular internal dimension in diastole (RVIDd) (3.9 ± 0.75 cm vs. 3.7 ± 0.78 cm) and tricuspid annular plane systolic excursion (TAPSE) (1.8 ± 0.44 cm vs. 2.0 ± 0.38 cm) were not statistically different between patients with or without RV strain on CT. A higher proportion of patients with an elevated troponin had RV enlargement (58% vs. 14%, p=0.001) and RVD (50% vs. 18%, p=0.018) on TTE. Length of hospital admission (16 ± 28 days vs. 11 ± 23 days) and in-hospital death (7% vs. 11%) were not statistically different between patients with or without TTE. Conclusions: Inpatient TTE is conducted frequently in hospitalized patients with acute PE, especially in those with evidence of RV strain based on CT and/or an elevated cardiac troponin. Our results suggest that patients with findings of RV strain on CT are more likely to have RV enlargement and RVD on TTE. Future studies should evaluate the diagnostic utility of CT and/or troponin for RVD in the setting of acute PE, which may reduce the routine use of inpatient TTE and associated healthcare resources and costs.

Limited data exist that comprehensively describe the practical management, in-hospital outcomes, healthcare resource utilization, and rates of post-hospital readmission among patients with submassive and massive pulmonary embolism (PE). Consecutive discharges for acute PE were identified from a single health system over 3 years. Records were audited to confirm presence of acute PE, patient characteristics, disease severity, medical treatment, and PE-related invasive therapies. Rates of in-hospital major bleeding and death, hospital length of stay (LOS), direct costs, and hospital readmission are reported. From January 2016 to December 2018, 371 patients were hospitalized for acute massive or submassive PE. In-hospital major bleeding (12.1%) was common, despite low utilization of systemic thrombolysis (1.8%) or catheter-directed thrombolysis (3.0%). In-hospital death was 10-fold higher among massive PE compared to submassive PE (36.6% vs 3.3%, p < 0.001). Massive PE was more common during hospitalizations not primarily related to venous thromboembolism, including hospitalizations primarily for sepsis or infection (26.8% vs 8.2%, p = 0.001). Overall, the median LOS was 6.0 days (IQR, 3.0–11.0) and the median standardized direct cost of admissions was $10,032 (IQR, $4467–$20,330). Rates of all-cause readmission were relatively high throughout late follow-up but did not differ between PE subgroups. Despite low utilization of thrombolysis, in-hospital bleeding remains a common adverse event during hospitalizations for acute PE. Although massive PE is associated with high risk for in-hospital bleeding and death, those successfully discharged after a massive PE demonstrate similar rates of readmission compared to submassive PE into late follow-up.

SummaryThe management of acute pulmonary embolism (PE) is often challenging and requires specific medical expertise, diagnostic techniques and therapeutic options that may not be available in all hospitals throughout the entire week. The aim of our study was to evaluate whether or not an association exists between weekday or weekend admission and mortality for patients hospitalised with acute PE. Using routinely collected hospital administrative data, we examined patients discharged with a diagnosis of PE from the hospitals of the Emilia- Romagna Region in Italy (January 1999-December 2009). The risk of inhospital death was calculated for admissions at the weekend and compared to weekday admissions. Of a total of 26,560 PEs, 6,788 (25.6%) had been admitted during weekends. PE admissions were most frequent on Mondays (15.8%) and less frequent on Saturdays and Sun- days/holidays (12.8%) (p<0.001). Weekend admissions were associated with significantly higher rates of in-hospital mortality than weekday admissions (28% vs. 24.8%) (p<0.001). The risk of weekend admission and in-hospital mortality was higher after adjusting for sender, hospital characteristics, and the Charlson co-morbidity index. In conclusion, hospitalisation for PE on weekends seems to be associated with a significantly higher mortality rate than on weekdays. Further research is needed to investigate the reasons for this observed difference in mortality in order to try and implement future strategies that ensure an adequate level of care throughout the entire week.

Abstract Background New management, risk stratification and treatment strategies have become available over the last years for patients with acute pulmonary embolism (PE), potentially leading to changes in clinical practice and improvement of patients’ outcome. Methods The COntemporary management of Pulmonary Embolism (COPE) is a prospective, non-interventional, multicentre study in patients with acute PE evaluated at internal medicine, cardiology and emergency departments in Italy. The aim of the COPE study is to assess contemporary management strategies in patients with acute, symptomatic, objectively confirmed PE concerning diagnosis, risk stratification, hospitalization and treatment and to assess rates and predictors of in-hospital and 30-day mortality. The composite of death (either overall or PE-related) or clinical deterioration at 30 days from the diagnosis of PE, major bleeding occurring in hospital and up to 30 days from the diagnosis of PE and adherence to guidelines of the European Society of Cardiology (ESC) are secondary study outcomes. Participation in controlled trials on the management of acute PE is the only exclusion criteria. Expecting a 10–15%, 3% and 0.5% incidence of death for patients with high, intermediate or low-risk PE, respectively, it is estimated that 400 patients with high, 2100 patients with intermediate and 2500 with low-risk PE should be included in the study. This will allow to have about 100 deaths in study patients and will empower assessment of independent predictors of death. Conclusions COPE will provide contemporary data on in-hospital and 30-day mortality of patients with documented PE as well as information on guidelines adherence and its impact on clinical outcomes.

Abstract Background Acute pulmonary embolism (PE) is one of the most critical cardiovascular diseases. PE treatment ranges from anticoagulation, and systemic thrombolysis to surgical embolectomy and catheter embolectomy. Surgical pulmonary embolectmy (SPE) indications and outcomes are still controversial. Although there have been more favourable SPE reports over the past decades, SPE has not yet been considered broadly as an initial PE therapy and is still considered as a reserve or rescue treatment for acute massive PE when systemic thrombolysis fails. This study aimed to evaluate the early and midterm outcomes of SPE, which was a first-line therapy for acute central major PE in one Chinese single centre. Methods A retrospective review of patients who underwent SPE for acute PE was conducted.Patients with chronic thrombus or who underwent thromboendarterectomy were excluded. SPE risk factors for morbidity and mortality were reviewed, and echocardiographic examination were conducted for follow-up studies to access right ventricular function. Results Overall, 41 patients were included; 17 (41.5%) had submassive PE, and 24 (58.5%) had massive PE. Mean cardiopulmonary bypass time was 103.2 ± 48.9 min, and 10 patients (24.4%) underwent procedures without aortic cross-clamping. Ventilatory support time was 78 h (range, 40–336 h), intensive care unit stay was 7 days (range, 3–13 days), and hospital stay was 16 days (range, 12–23 days). Operative mortalities occurred in 3 massive PE patients, and no mortality occurred in submassive PE patients. The overall SPE mortality rate was 7.31% (3/41). If two systemic thrombolysis cases were excluded, SPE mortality was low (2.56%,1/39), evenlthough there were 2 cases of cardiac arrest preoperatively. Patients’ right ventricle function improved postoperatively in follow-ups.There were no deaths related to recurrent PE and chronic pulmonary hypertension in follow-ups, though 3 patients died of cerebral intracranial bleeding, gastric cancer,and brain cancer at 1 year, 3 years, and 8 years postoperatively, respectively. Conclusions SPE presented with a low mortality rate when rendered as a first-line treatment in selected massive and submassive acute PE patients. Favorable outcomes of right ventricle function were also observed in the follow-ups. SPE should play the same role as ST in algorithmic acute PE treatment.

Abstract Background Whether early oral anticoagulant treatment is appropriate for patients with acute pulmonary embolism (PE) regardless of PE severity is undefined. The aim of this study in patients with acute PE at intermediate risk of death were: I) to assess the determinants for the use of early vs delayed vs no oral anticoagulants in patients with acute PE and II) to assess the association between timing of oral anticoagulation and in-hospital mortality. Methods Prospective cohorts of patients with acute PE at intermediate risk of death according to the European Society of Cardiology Guidelines 2014 were merged in a collaborative database. The initiation of oral anticoagulation was classified as early (≤3 days) or delayed (between day 3 and 10 from diagnosis). Patients treated with parenteral anticoagulants for longer than 10 days were also included. In-hospital death was the primary study outcome. Results Overall, 557 patients were included in the study, 23 received thrombolytic treatment during the hospital stay. The mean duration of parenteral anticoagulation was 7±8 days (5 median), 348 patients were initiated on a direct oral anticoagulant and 79 on a vitamin K antagonist during the hospital stay. Initiation of oral anticoagulants occurred early or delayed in 209 (37%) and 218 (39%) patients, respectively and never occurred during the first 30 days in 130 (23%). Intermediate-low risk patients more commonly received early and intermediate high delayed oral anticoagulation. Simplified PESI score of zero (OR 1.9, 95% CI 1.3–2.7) was independently associated with early oral anticoagulation; among sPESI components absence of cancer (OR 5.9, 95% CI 3.3–10) and heart rate <110 (OR 1.8, 95% CI 1.01–3.16) were independent predictors of early initiation of oral anticoagulants. The presence of both right ventricle dysfunction and injury was associated with delayed initiation of oral anticoagulants. The incidence of death was 5.5%. Death occurred in 32 patients and was not related to the duration of parenteral anticoagulation (OR 1.01 per day, 95% CI 0.98–1.06) nor to right ventricle dysfunction but to sPESI 1 (OR 3.32, 95% CI 1.14–9.66). These results were partially confirmed in the 435 intermediate risk patients without cancer (OR 1.03, 95% CI 0.99–1.08 for days of parenteral treatment; OR 4.17, 95% CI 0.95–18 for sPESI 1). Conclusion The clinical severity of PE and not the timing of initiation of oral anticoagulants are associated with in-hospital death in patients with intermediate risk PE. Randomized studies are needed to definitively assess the role of heparin lead-in in patients with PE at intermediate risk for death.

Acute pulmonary embolism (PE) is a life-threatening condition. In patient who has contraindication for systemic thrombolysis and inappropriate for surgical embolectomy, there is a role of catheter interventions. However, the data are limited. The aim of the present report was to assess a role of intrapulmonary artery thrombolysis bolus in acute PE. A retrospective review of the use of intrapulmonary artery thrombolysis in acute PE. The data were collected from 14 patients with massive or submassive PE who had contraindication or inappropriate for systemic thrombolysis and unsuitable for surgical embolectomy. After intrapulmonary thrombolysis was given, patients were followed clinically and hemodynamically until discharged and after 1 month. Pulmonary pressure was collected at pre and post intervention. Of the 14 patients (age 59±19 years, 78.6% female), 86% were diagnosed as submassive PE. Mean dose of tissue plasminogen activator (rt-PA) was 28±14 mg given as bolus and continuous infusion (19±10 hours). One patient died after completion of intrapulmonary infusion rt-PA at day 90, which did not relate to PE and the treatment. After intervention, mean PA pressure was significantly reduced from 32.3±6.0 to 21.0±4.3 mmHg (p<0.001). Three patients (21%) had minor bleeding (hematoma at access site). The present case series showed that intrapulmonary infusion of rt-PA was effective and safe in patient with massive and submassive PE who had contraindication or inappropriate to systemic thrombolysis or inoperable surgical thrombectomy.

Introduction: Acute pulmonary embolism is a confirmed cause of up to 5% of out-of-hospital cardiac arrest and 5%–13% of unexplained cardiac arrest in patients. However, the true incidence may be much higher, as pulmonary embolism is often clinically underdiagnosed. Thrombolytic therapy is a recognized therapy for pulmonary embolism–associated cardiac arrest but is not routinely recommended during cardiopulmonary resuscitation. Therefore, clinicians should attempt to identify patients with suspected pulmonary embolism. Many point-of care ultrasound protocols suggest diagnosis of pulmonary embolism for cardiac arrest patients. Case presentation: We describe two male patients (60 years and 66 years, respectively) who presented to the emergency department with cardiac arrest within a period of 1 week. With administration of point-of care ultrasound during the ongoing cardiopulmonary resuscitation in both patients, fibrinolytic therapy was initiated under suspicion of cardiac arrest caused by pulmonary embolism. Both patients had return of spontaneous circulation; however, only the second patient, who received fibrinolytic therapy relatively early, was discharged with a good outcome. In this report, we discussed how to diagnose and manage patients with cardiac arrest–associated pulmonary embolism with the help of point-of care ultrasound. We also discuss the different clinical outcomes of the two patients based on the experience of the clinicians and the timing of thrombolytic agent application. Conclusions: If acute pulmonary embolism is suspected in patients with out-of-hospital cardiac arrest, we recommend prompt point-of care ultrasound examination. Point-of care ultrasound may help identify patients with pulmonary embolism during cardiopulmonary resuscitation, leading to immediate treatment, although the clinical outcomes may vary.

Acute Pe

It has been speculated that the atypical clinical presentation of acute pulmonary embolism (PE) in older patients leads to a late diagnosis and therefore contributes to a worse prognosis. Therefore, we prospectively evaluated the delay in diagnosis and its relation to the in-hospital mortality in 202 patients with acute PE. Patients >65 years presented more often with hypoxia ( P = .017) and with a history of syncope ( P = .046). Delay in diagnosis was not statistically different in both age groups. Older age was significantly associated with an increased risk for in-hospital mortality (OR 4.36, 95% CI 0.93-20.37, P = .043), whereas the delay in diagnosis was not associated with an increase of in-hospital mortality. We therefore conclude that the clinical presentation of acute PE in older patients cannot be considered as a risk factor for late diagnosis and is not responsible for their higher in-hospital death rate.

Abstract Background: Veno-arterial extracorporeal membrane oxygenation (ECMO) is increasingly being utilized in patients with massive pulmonary embolism (PE). However, the efficacy and the safety remain uncertain. This study aimed to investigate clinical courses and outcomes in ECMO-treated patients with acute PE.Methods: Twenty-one patients with acute PE rescued by ECMO from January 2012 to December 2019 were retrospectively analysed. Clinical features, laboratory biomarkers, and imaging findings of these patients were reviewed, and the relationship with immediate outcome and clinical course was investigated.Results: Sixteen patients (76.2%) experienced refractory circulatory collapse requiring cardiopulmonary resuscitation (CPR) or ECMO support within 2 hours after the onset of cardiogenic shock, and none could receive definitive reperfusion therapy before ECMO initiation. Before or during ECMO support, more than 90% of patients had imaging signs of right ventricular (RV) dysfunction. In normotension patients, the computed tomography (CT) value was a valuable predictor of rapid disease progression compared with cardiac troponin I level. Ultimately, in-hospital death occurred in 10 patients (47.6%) and 90% of them died of prolonged CPR-related brain death. Cardiac arrest was a significant predictor of poor prognosis (p = 0.001). Conclusions: ECMO appears to be a safe and effective circulatory support in patients with massive PE. Close monitoring in intensive care unit is recommended in patients with RV dysfunction and aggressive use of ECMO may reduce the risk of sudden cardiac arrest and improve clinical outcome.
