Background Certain echocardiographic parameters may serve as early predictors of adverse events in patients with hemodynamically compromising pulmonary embolism (PE). Methods and Results An observational analysis was conducted for patients with acute pulmonary embolism evaluated by a Pulmonary Embolism Response Team (PERT) between 2014 and 2020. The performance of clinical prediction algorithms including the Pulmonary Embolism Severity Index and Carl Bova score were compared using a ratio of right ventricle and left ventricle hemodynamics by dividing the pulmonary artery systolic pressure by the left ventricle stroke volume. The primary outcome of in‐hospital mortality, cardiac arrest, and the need for advanced therapies was evaluated by univariate and multivariable analyses. Of the 343 patients meeting the inclusion criteria, 215 had complete data. Pulmonary artery systolic pressure/left ventricle stroke volume was a clear predictor of the primary end point (odds ratio [OR], 2.31; P =0.005), performing as well or better than the Pulmonary Embolism Severity Index (OR, 1.43; P =0.06) or the Bova score (OR, 1.28; P =0.01). Conclusions This study is the first study to demonstrate the utility of early pulmonary artery systolic pressure/left ventricle stroke volume in predicting adverse clinical events in patients with acute pulmonary embolism. Pulmonary artery systolic pressure/left ventricle stroke volume may be a surrogate marker of ventricular asynchrony in high‐risk pulmonary embolism and should be prognostically evaluated.

Introduction: Risk stratification tools including the Pulmonary Embolism Severity Index (PESI) and BOVA rely on complicated calculations that give less attention to hemodynamic parameters predictive of cardiogenic shock in acute pulmonary embolism (PE). We explored the possibility that simultaneous measurement of right sided and left sided non-invasive hemodynamic parameters by echocardiography may predict adverse sequelae in the context of acute PE. Methods: We retrospectively reviewed all Pulmonary Embolism Response Team (PERT) activations between 2014 and 2020. The PESI and BOVA scores were calculated and their performance in predicting adverse events was compared to pulmonary artery elastance (PAE). PAE (mmHg/mL) was calculated by dividing the Pulmonary Artery Systolic pressure (PASP) by the LV Stroke (SV). Blood biomarkers (troponin T, NT-proBNP, and lactate) were recorded. The composite primary outcome was: 1) need for advanced intervention, 2) cardiac arrest, and 3) in-hospital mortality. Multivariate and univariate regression was used to analyze outcomes. Results: 215 of 343 patients met inclusion criteria. Baseline characteristics were similar in patients with PAE <1 and PAE ≥ 1. PAE ≥ 1 was common in intermediate-high risk PE (85.7% vs 63.1%, p <0.001), with greater [NT-proBNP, pg/mL] (3599 vs 1427.5, p=0.001) and [lactate, mM] (2.9 vs 1.8. p=0.003). PAE ≥ 1 predicted the composite endpoint with odds ratio (OR) of 2.31 (95% CI 1.3-4.2, p=0.005), Comparatively BOVA had adjusted OR of 1.3 (95% CI, 1.1-1.6, p = 0.01) and PESI was not significant with OR of 1.4 (95% CI, 1 -2.1, p = 0.055) in predicting composite outcomes. Conclusion: In the context of acute high risk PE, PAE ≥ 1.0 is a novel and independent predictor of adverse cardiovascular events and mortality that should be prospectively validated.

ABSTRACT CONTEXT AND OBJECTIVE: The location of embolism is associated with clinical findings and disease severity in cases of acute pulmonary embolism. The level of gamma-glutamyl transferase increases under oxidative stress-related conditions. In this study, we investigated whether gamma-glutamyl transferase levels could predict the location of pulmonary embolism. DESIGN AND SETTING: Hospital-based cross-sectional study at Cumhuriyet University, Sivas, Turkey. METHODS : 120 patients who were diagnosed with acute pulmonary embolism through computed tomography-assisted pulmonary angiography were evaluated. They were divided into two main groups (proximally and distally located), and subsequently into subgroups according to thrombus localization as follows: first group (thrombus in main pulmonary artery; n = 9); second group (thrombus in main pulmonary artery branches; n = 71); third group (thrombus in pulmonary artery segmental branches; n = 34); and fourth group (thrombus in pulmonary artery subsegmental branches; n = 8). RESULTS : Gamma-glutamyl transferase levels on admission, heart rate, oxygen saturation, right ventricular dilatation/hypokinesia, pulmonary artery systolic pressure and cardiopulmonary resuscitation requirement showed prognostic significance in univariate analysis. The multivariate logistic regression model showed that gamma-glutamyl transferase level on admission (odds ratio, OR = 1.044; 95% confidence interval, CI: 1.011-1.079; P = 0.009) and pulmonary artery systolic pressure (OR = 1.063; 95% CI: 1.005-1.124; P = 0.033) remained independently associated with proximally localized thrombus in pulmonary artery. CONCLUSIONS : The findings revealed a significant association between increased existing embolism load in the pulmonary artery and increased serum gamma-glutamyl transferase levels.

Introduction. This study aimed to investigate the currency of computerized tomography pulmonary angiography-based parameters as pulmonary artery obstruction index (PAOI), as well as right ventricular diameters for pulmonary embolism (PE) risk evaluation and prediction of mortality and intensive care unit (ICU) requirement.Materials and Methods. The study retrospectively enrolled 203 patients hospitalized with acute PE. PAOI was calculated according to Qanadli score.Results. Forty-three patients (23.9%) were hospitalized in the ICU. Nineteen patients (10.6%) died during the 30-day follow-up period. The optimal cutoff value of PAOI for PE 30th day mortality and ICU requirement were found as 36.5% in ROC curve analysis. The pulmonary artery systolic pressure had a significant positive correlation with right/left ventricular diameter ratio (r=0.531,P<0.001), PAOI (r=0.296,P<0.001), and pulmonary artery diameter (r=0.659,P<0.001). The patients with PAOI values higher than 36.5% have a 5.7-times increased risk of death.Conclusion. PAOI is a fast and promising parameter for risk assessment in patients with acute PE. With greater education of clinicians in this radiological scoring, a rapid assessment for diagnosis, clinical risk evaluation, and prognosis may be possible in emergency services without the need for echocardiography.

Abstract Funding Acknowledgements Type of funding sources: None. Background Pulmonary embolism (PE) is the third global cause of cardiovascular death. Treatment of high-risk cases and selected intermediate-risk cases is based on systemic thrombolysis, which can be inconvenient in patients with a contraindications for thrombolysis. Catheter-directed therapies are emerging as an alternative for treatment when there is an increased bleeding risk. Methods One-center retrospective study of patients with high or intermediate-high risk PE with contraindications for systemic thrombolysis. Catheter directed rheolytic thrombectomy or mechanical thrombectomy was performed, assessing its effect on clinical variables, pulmonary artery systolic pressure (PASP), PaO2/FiO2, and the occurrence of complications. Results In 12 patients with PE treated with catheter-directed therapy, we observed a mean increase of the PaO2/FiO2 of 62 mm Hg (p = 0.013), as well mean reduction in the PASP of 13 mm Hg (p &lt; 0.001), as can be observed in the figure. As complications, there was one case of hemoptysis, and two of hemolysis, with an in-hospital mortality of 16.7%. Conclusion Catheter-directed therapy in patients with high or intermediate-high risk PE is a feasible option when there are contraindications for thrombolysis or there is a high bleeding risk. It has been shown to improve surrogate endpoints as PASP and right to left ventricle ratio in other studies, although data on mortality from a randomized trial is lacking. Abstract Figure.

Abstract We sought to examine the influence of clinically severe lower respiratory tract infection on pulmonary artery pressure in children having CHD with post-tricuspid left-to-right shunt, as it may have physiological and clinical implications. In a prospective single-centre observational study, 45 children with post-tricuspid left-to-right shunt and clinically severe lower respiratory tract infection were evaluated during the illness and 2 weeks after its resolution. Pulmonary artery systolic pressure was estimated non-invasively using shunt gradient by echocardiography and systolic blood pressure measured non-invasively. Median pulmonary artery systolic pressure during lower respiratory tract infection was only mildly (although statistically significantly) elevated during lower respiratory tract infection [60 (42–74) versus 53 (40–73) mmHg, (p < 0.0001)]. However, clinically significant change in pulmonary artery systolic pressure defined as the increase of >10 mmHg was present in only 9 (20%) patients. In the absence of hypoxia or acidosis, only a small minority (9%, n = 4) showed significant pulmonary artery systolic pressure rise >10 mmHg. In the absence of hypoxia or acidosis, severe lower respiratory tract infection in patients with acyanotic CHD results in only mild elevation of pulmonary artery systolic pressure in most of the patients.

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.

Rv Function

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.
