Abstract Background Contemporary Australian epidemiological data on acute pulmonary embolism (PE) are lacking. Objectives To determine the admission rates of acute PE in Australia, and to assess the temporal trends in short- and medium-term mortality following acute PE. Methods Retrospective population-linkage study of all New South Wales residents admitted with a primary diagnosis of PE between January 1, 2002 and December 31, 2018 using data from the Centre for Health Record Linkage databases. Main outcome measures included temporal trends in total PE admissions and all-cause mortality at prespecified time points up to 1 year, stratified by gender. Results There were 61,607 total PE admissions between 2002 and 2018 (mean ± standard deviation: 3,624 ± 429 admissions per annum; 50.42 ± 3.70 admissions per 100,000 persons per annum). The mean admission rate per annum was higher for females than for males (54.85 ± 3.65 vs. 44.91 ± 4.34 admissions per 100,000 persons per annum, respectively) and remained relatively stable for both genders throughout the study period. The main study cohort, limited to index PE admission only, comprised 46,382 persons (mean age: 64.6 ± 17.3 years; 44.4% males). The cumulative in-hospital, 30-day, 3-month, and 1-year mortality rates were 3.7, 5.6, 9.6, and 16.8%, respectively. When compared with 2002 as the reference year, there was a significant reduction in in-hospital (odds ratio [OR] = 0.34; 95% confidence interval [CI] = 0.25–0.46), 30-day (OR = 0.58, 95% CI = 0.46–0.73), and 1-year (hazard ratio = 0.74, 95% CI = 0.66–0.84) (all p < 0.001) mortality risk by 2017 after adjusting for age, gender, and relevant confounders. The survival improvements were seen in both genders and were greater for females than for males. Conclusion Mortality following PE has improved with reductions observed in both short- and medium-term follow-ups between 2002 and 2018 with greater reductions in females despite their higher admission rates over time.

ObjectivesAnaemia is associated with increased mortality in acute pulmonary embolism (PE) patients. However, prior studies have not examined the prognostic impact of trends in plasma haemoglobin during admission. This study investigates the impact of changes in haemoglobin level on mortality during hospital stay in acute PE.Study designA retrospective observational study.SettingTertiary-referral centre in Australia.ParticipantsConsecutive patients from 2000 to 2012 admitted with confirmed acute PE were identified from a dedicated PE database. Haemoglobin levels on days 1, 3–4, 5–6 and 7 of admission were retrieved. Patients without both baseline haemoglobin and subsequent haemoglobin levels were excluded (n=327), leaving 1099 patients as the study cohort. Anaemia was defined as haemoglobin <130 g/L for men and <120 g/L for women. There were 576 patients without anaemia throughout admission, 65 with transient anaemia (anaemic on day 1, but subsequently normalised during admission), 122 with acquired anaemia (normal on day 1 but developed anaemia during admission) and 336 with persistent anaemia. A total of 71 patients received blood transfusion during admission.Main outcome measure6-month mortality was tracked from a state-wide death database and analysed using multivariable modelling.ResultsAfter adjusting for transfusion, patietns with persistent anaemia had a significantly increased 6-month mortality risk (adjusted HR 1.97, 95% CI 1.26 to 3.09, p=0.003) compared with patients without anaemia. There was no difference in mortality between patients with transient or acquired anaemia and patients without anaemia.ConclusionAmong patients who had anaemia during their admission for acute PE, only the subgroup with persistent anaemia demonstrated worse outcomes.

Abstract. Background: The aim of this meta-analysis was to evaluate the diagnostic accuracy of magnetic resonance angiography (MRA) for acute pulmonary embolism (PE). Methods: A systematic literature search was conducted that included studies from January 2000 to August 2015 using the electronic databases PubMed, Embase and Springer link. The summary receiver operating characteristic (SROC) curve, sensitivity, specificity, positive likelihood ratios (PLR), negative likelihood ratios (NLR), and diagnostic odds ratio (DOR) as well as the 95 % confidence intervals (CIs) were calculated to evaluate the diagnostic accuracy of MRA for acute PE. Meta-disc software version 1.4 was used to analyze the data. Results: Five studies were included in this meta-analysis. The pooled sensitivity (86 %, 95 % CI: 81 % to 90 %) and specificity (99 %, 95 % CI: 98 % to 100 %) demonstrated that MRA diagnosis had limited sensitivity and high specificity in the detection of acute PE. The pooled estimate of PLR (41.64, 95 % CI: 17.97 to 96.48) and NLR (0.17, 95 % CI: 0.11 to 0.27) provided evidence for the low missed diagnosis and misdiagnosis rates of MRA for acute PE. The high diagnostic accuracy of MRA for acute PE was demonstrated by the overall DOR (456.51, 95 % CI: 178.38 - 1168.31) and SROC curves (AUC = 0.9902 ± 0.0061). Conclusions: MRA can be used for the diagnosis of acute PE. However, due to limited sensitivity, MRA cannot be used as a stand-alone test to exclude acute PE.

Abstract Funding Acknowledgements Type of funding sources: Foundation. Main funding source(s): Laerdal Foundation for Acute Medicine, Novo Nordisk Foundation Background/Introduction: Acute pulmonary embolism (PE) is a frequent condition in acute cardiac care and is potentially fatal. Cause of death is right ventricular (RV) failure due to increased RV afterload from both pulmonary vascular obstruction and vasoconstriction. Inodilators are interesting drugs of choice as they may improve RV function and lower its afterload. Purpose We aimed to investigate the cardiovascular effects of three clinically relevant inodilators: levosimendan, milrinone and dobutamine in acute PE. Methods We conducted a randomized, blinded, animal study using 18 female pigs. Animals received large autologous PE until doubling of baseline mean pulmonary arterial pressure and were randomized to four logarithmically increasing doses of each inodilator. Effects were evaluated with bi-ventricular pressure-volume loop recordings, right heart catheterization and blood gas analyses. Results Induction of PE increased RV afterload and pulmonary pressure (p &lt; 0.05) causing RV dysfunction. Levosimendan and milrinone showed beneficial hemodynamic profiles by lowering RV pressures and volume (p &lt; 0.001) and improved RV function and cardiac output (p &lt; 0.05) without increasing RV mechanical work. Dobutamine increased RV pressure and function (p &lt; 0.01) but at a cost of increased mechanical work at the highest doses, showing an adverse hemodynamic profile. See Figure. Conclusion(s): In a porcine model of acute PE, levosimendan and milrinone reduced RV afterload and improved RV function, whereas dobutamine at higher doses increased RV afterload and RV mechanical work. The study motivates clinical testing of inodilators in patients with acute PE and RV dysfunction. Abstract Figure. Inodilators in acute pulmonary embolism

Abstract Background Computed tomography pulmonary angiography (CTPA) is the imaging modality of choice for the diagnosis of acute pulmonary embolism (PE). With computed tomography pulmonary perfusion (CTPP) additional information on lung perfusion can be assessed, but its value in PE risk stratification is unknown. We aimed to evaluate the correlation between CTPP-assessed perfusion defect score (PDS) and clinical presentation and its predictive value for adverse short-term outcome of acute PE. Patients and Methods This was an exploratory, observational study in 100 hemodynamically stable patients with CTPA-confirmed acute PE in whom CTPP was performed as part of routine clinical practice. We calculated the difference between the mean PDS in patients with versus without chest pain, dyspnea, and hemoptysis and 7-day adverse outcome. Multivariable logistic regression analysis and likelihood-ratio test were used to assess the added predictive value of PDS to CTPA parameters of right ventricle dysfunction and total thrombus load, for intensive care unit admission, reperfusion therapy and PE-related death. Results We found no correlation between PDS and clinical symptoms. PDS was correlated to reperfusion therapy (n = 4 with 16% higher PDS, 95% confidence interval [CI]: 3.5–28%) and PE-related mortality (n = 2 with 22% higher PDS, 95% CI: 4.9–38). Moreover, PDS had an added predictive value to CTPA assessment for PE-related mortality (from Chi-square 14 to 19, p = 0.02). Conclusion CTPP-assessed PDS was not correlated to clinical presentation of acute PE. However, PDS was correlated to reperfusion therapy and PE-related mortality and had an added predictive value to CTPA-reading for PE-related mortality; this added value needs to be demonstrated in larger studies.

Abstract Background It is important to identify deterioration in normotensive patients with acute pulmonary embolism (PE). This study aimed to develop a tool for predicting deterioration among normotensive patients with acute PE on admission. Methods Clinical, laboratory, and computed tomography parameters were retrospectively collected for normotensive patients with acute PE who were treated at a Chinese center from January 2011 to May 2020 on admission into the hospital. The endpoint of the deterioration was any adverse outcome within 30 days. Eligible patients were randomized 2:1 to derivation and validation cohorts, and a nomogram was developed and validated by the aforementioned cohorts, respectively. The areas under the curves (AUCs) with 95% confidence intervals (CIs) were calculated. A risk-scoring tool for predicting deterioration was applied as a web-based calculator. Results The 845 eligible patients (420 men, 425 women) had an average age of 60.05 ± 15.43 years. Adverse outcomes were identified for 81 patients (9.6%). The nomogram for adverse outcomes included heart rate, systolic pressure, N-terminal-pro brain natriuretic peptide, and ventricle/atrial diameter ratios at 4-chamber view, which provided AUC values of 0.925 in the derivation cohort (95% CI 0.900–0.946, p < 0.001) and 0.900 in the validation cohort (95% CI 0.883–0.948, p < 0.001). A risk-scoring tool was published as a web-based calculator (https://gaoyzcmu.shinyapps.io/APE9AD/). Conclusions We developed a web-based scoring tool that may help predict deterioration in normotensive patients with acute PE.

SummaryRight ventricular (RV) function is of major prognostic significance in patients with acute pulmonary embolism (PE). The aim of the present study was to evaluate the role of neurohormone plasma brain natriuretic peptide (BNP) in assessing RV function in patients with acute PE.BNP levels were measured in 16 consecutive patients with acute PE as diagnosed by high probability lung scintigraphy or pulmonary angiography. Twelve healthy age-matched volunteers served as controls. All 16 patients underwent standard echocardiography and blood tests during the first hour of presentation. In the patient group, survival was studied for a period of 30 days. Plasma BNP levels in patients with acute PE were higher than in controls (7.2 [95% CI 0.4 to 144.6] versus 1.4[95% CI 0.4 to 4.6] pmol/L, p = 0.0008). Plasma BNP was significantly higher in 5 patients with RV dysfunction compared to 11 patients with normal RV function (40.2 [95% CI 7.5 to 214.9] versus 3.3 [95% CI 0.4 to 24.9] pmol/L, p = 0.0003). RV systolic pressure was not significantly correlated with BNP (r = 0.42, p = ns).In conclusion, plasma BNP neurohormone levels might be of clinical importance as a supplementary tool for assessment of RV function in patients with acute PE.

Our aim was to prospectively assess the prognostic value of beta2- microglobulin (b2-M) in patients with acute pulmonary embolism (PE). We conducted a prospective study of 109 patients admitted in a pulmonary clinic due to acute PE. A panel of inflammatory markers including b2-M white blood cell (WBC) count and C-reactive protein (CRP) was determined for each patient. In this preliminary study, baseline b2-M levels significantly correlated with the impairment of oxygenation and with all the parameters that are used for the early risk stratification of patients. In multivariate analysis, patients’ age and baseline b2-M levels were significantly associated with an increased risk of death. These findings require further prospective validation.

Introduction: Pulmonary Embolism in coronavirus disease 2019 (COVID-19) patients have been increasingly reported in observational studies. However, limited knowledge describing their diagnostic features and clinical outcomes exist to date. Our study aims to systemically analyze their clinical characteristics and to investigate strategies for risk stratification. Methods: We retrospectively studied 101 patients with concurrent diagnoses of acute pulmonary embolism and COVID-19 infection, admitted at two tertiary hospitals within the Northwell Health System in New York City area. Clinical features including laboratory and imaging findings, therapeutic interventions, intensive care unit (ICU) admission, mortality and length of stay were recorded. D-dimer values were respectively documented at COVID-19 and PE diagnoses for comparison. Pulmonary Severity Index (PESI) scores were used for risk stratification of clinical outcomes. Results: The most common comorbidities were hypertension (50%), obesity (27%) and hyperlipidemia (32%) among our study cohort. Baseline D-dimer abnormalities (4647.0 ± 8281.8) were noted on admission with a 3-fold increase at the time of PE diagnosis (13288.4 ± 14917.9; p<0.05). 5 (5%) patients required systemic thrombolysis and 12 (12%) patients experienced moderate to severe bleeding. 31 (31%) patients developed acute kidney injury (AKI) and 1 (1%) patient required renal replacement therapy. Throughout hospitalization, 23 (23%) patients were admitted to intensive care units, of which 20 (20%) patients received invasive mechanical ventilation. The overall mortality rate was 20%. Majority of patients (65%) had Intermediate to high risk PESI scores (>85), which portended a worse prognosis with higher mortality rate and length of stay. Conclusions: This study provides characteristics and early outcomes for hospitalized patients with COVID-19 and acute pulmonary embolism. D-dimer levels and PESI scores may be utilized to risk stratify and guide management in this patient population. Our results should serve to alert the medical community to heighted vigilance of this VTE complication associated with COVID-19 infection, despite the preliminary and retrospective nature inherent to this study.
