BACKGROUND: Residual pulmonary vascular obstruction (RPVO) is common following pulmonary embolism (PE) but its association with fibrin clot properties is poorly understood. We investigated whether prothrombotic state and hypofibrinolysis markers can identify patients with RPVO. METHODS: In 79 normotensive noncancer patients (aged 56 ± 13.3 years) with acute PE, we determined fibrin clot permeability (Ks ), clot lysis time (CLT), endogenous thrombin potential (ETP), fibrinolysis proteins, oxidative stress markers, and E-selectin on admission before initiation of anticoagulant therapy, after 5-7 days, and 3 months of anticoagulation...

BACKGROUND: The RIETE score could be specifically useful for identification of low-risk pulmonary embolism (PE) patients for home treatment. However, the external validation of the RIETE score has been limited. METHODS: The COMMAND VTE Registry is a multicenter registry enrolling consecutive patients with acute symptomatic venous thromboembolism (VTE). The current study population consisted of 1479 patients with acute PE, who were divided into 2 groups; RIETE scores of 0 (N = 260) and ≥ 1 (N = 1219)...

PURPOSE: Acute pulmonary embolism (PE) poses a life-threatening risk with high mortality rates. While the coexistence of PE and obstructive sleep apnea (OSA) is gaining recognition, its influence on PE severity and prognosis remains uncertain. This study aims to investigate the associations between OSA and disease severity, as well as outcomes, in patients with acute PE. PATIENTS AND METHODS: We conducted a retrospective cohort study on patients diagnosed with acute PE who had undergone previous cardiorespiratory polygraphy...

BACKGROUND: Echocardiographic markers of right ventricular dysfunction or pressure overload (RVd/PO ) have been used in risk assessment of patients with acute pulmonary embolism (APE). Nevertheless, the role of echocardiography in these patients is incompletely determined. We evaluated the right ventricular function using 'non-conventional' markers of RVd/PO in patients with APE. METHODS: This was a prospective, single-arm, single-centre study. Consecutive adult patients hospitalised for APE were included...

INTRODUCTION: Acute pulmonary embolism (APE) is a hazardous disorder with a high mortality. Combination of clinical, radiological, and serological parameters can improve risk stratification of APE. Most of the proposed combined scores were not validated in independent cohorts. Our aim was to validate the proposed clinical-radiological scores for prognosis of 7- and 30-day mortality in APE. MATERIALS AND METHODS: Our sample comprised 531 patients with APE, mean age 64...

BACKGROUND: Pulmonary Embolism Severity Index (PESI) and simplified PESI (sPESI) methods are used in the evaluation of patients with suspected acute pulmonary thromboembolism (PTE). OBJECTIVES: This study aimed to provide a rapid mortality risk stratification in patients with acute pulmonary thromboembolism (PTE) immediately after admission without relying on laboratory data by using quick sequential organ failure assessment (qSOFA), a three-parameter scoring system with proven efficiency used for swift prediction of organ dysfunction, and compare it with Pulmonary Embolism Severity Index (PESI) and simplified PESI (sPESI)...

OBJECTIVES: We aimed to use machine learning (ML) algorithms to risk stratify the prognosis of critical pulmonary embolism (PE). MATERIAL AND METHODS: In total, 1229 patients were obtained from MIMIC-IV database. Main outcomes were set as all-cause mortality within 30 days. Logistic regression (LR) and simplified eXtreme gradient boosting (XGBoost) were applied for model constructions. We chose the final models based on their matching degree with data. To simplify the model and increase its usefulness, finally simplified models were built based on the most important 8 variables...

BACKGROUND: Pulmonary embolism (PE) is a severe condition that causes significant mortality and morbidity. Due to its acute nature, scores have been developed to stratify patients at high risk of 30-day mortality. Here we develop a machine-learning based score to predict 30-day, 90-day, and 365-day mortality in PE patients. METHODS: The Birmingham and Black Country Venous Thromboembolism registry (BBC-VTE) of 2183 venous thromboembolism patients is used. Random forests were trained on a 70% training cohort and tested against 30% held-out set...

BACKGROUND: Identification of patients with acute symptomatic pulmonary embolism (PE) who are at low-risk for short-term complications to warrant outpatient care lacks clarity. METHOD: In order to identify patients at low-risk for 30-day all-cause and PE-related mortality, we used a cohort of haemodynamically stable patients from the RIETE registry to compare the false-negative rate of four strategies: the simplified Pulmonary Embolism Severity Index (sPESI); a modified (i...

INTRODUCTION AND OBJECTIVE: Several scoring systems have been developed for risk stratification in patients with acute pulmonary embolism (PE). The Pulmonary Embolism Severity Index (PESI) and its simplified version (sPESI) are among the most used, however the high number of variables hinder its application. Our aim was to derive an easy-to-perform score based on simple parameters obtained at admission to predict 30-day mortality in acute PE patients. METHODS: Retrospective study in 1115 patients with acute PE from two institutions (derivation cohort n=835, validation cohort n=280)...

Pulmonary embolism (PE) is the third most frequent cardiovascular disease, characterised by a wide range of presentations and clinical course. Prognostic assessment is a cornerstone of PE management as it determines the choice of both diagnostic and therapeutic strategies. During the last decades significant efforts have been made to safely select patients for early-discharged or home-treatment, but the appropriate risk-stratification, particularly of intermediate-risk patients, remains challenging. In addition to the guidelines recommended clinical prediction rules, such as PESI, sPESI and/or Hestia Criteria, a multimodality approach based also in biomarkers and cardiac imaging is crucial for risk-stratification and to select the appropriate management of the patients...

Obstructive sleep apnea (OSA) has been associated with the initiation and progression of cardiovascular disease. This study aimed to explore the relationship between the severity of OSA and the risk stratification of acute pulmonary embolism (PE). In this single-center cohort study, patients diagnosed with PE were evaluated for OSA via polygraphy monitoring. The simplified PE severity index (sPESI) and the number of patients requiring systemic thrombolysis were used to determine the severity of the disease...

Acute pulmonary embolism (PE) is a frequently diagnosed condition. Prediction of in-hospital deterioration is challenging with current risk models. The Calgary Acute Pulmonary Embolism (CAPE) score was recently derived to predict in-hospital adverse PE outcomes but has not yet been externally validated. Retrospective cohort study of normotensive acute pulmonary embolism cases diagnosed in our emergency department between 2017 and 2019. An external validation of the CAPE score was performed in this population for prediction of in-hospital adverse outcomes and a secondary outcome of 30-day all-cause mortality...

INTRODUCTION: It has been shown that there is a correlation between Obstructive Sleep Apnea Syndrome (OSAS) and pulmonary thromboembolism (PTE); OSAS is a risk factor for PTE. We aimed to evaluate the frequency of OSAS in PTE patients, the correlation of OSAS with the severity of PTE, and its effect on 1-month mortality in PTE patients. METHODS: This single-center, prospective, comparative case control study contains 198 patients diagnosed with non-massive PTE in our hospital between the dates of 01/07/2018-04/01/2020 who were confirmed by imaging methods...

OBJECTIVES: Existing pulmonary embolism (PE) risk scores were developed to predict death within weeks, but not more proximate adverse events. We determined the ability of 3 PE risk stratification tools (simplified pulmonary embolism severity index [sPESI], 2019 European Society of Cardiology guidelines [ESC], and PE short-term clinical outcomes risk estimation [PE-SCORE]) to predict 5-day clinical deterioration after emergency department (ED) diagnosis of PE. METHODS: We analyzed data from six EDs on ED patients with confirmed PE...

BACKGROUND: In prior studies, central pulmonary embolism (PE) was associated with high clot burden and was considered an independent predictor for thrombolysis. Further information about predictors of adverse outcomes in these patients is needed for better risk stratification. The objective is to describe independent predictors of adverse clinical outcomes in patients with central PE. METHODS: Large retrospective, observational, and single-center study of hospitalized patients with central PE...

BACKGROUND: To explore the prognostic risk factors of 30-day death in patients with traumatic lower limb fracture (TLLF) complicated with acute pulmonary embolism (APE). METHODS: 295 consecutive TLLF patients diagnosed as APE according to pulmonary artery CT angiography, hospitalized in our hospital from January 2017 to December 2021, were included in this study. Patients were divided into nonsurvival group and survival group according to 30-day follow-up results...

Approximately 5% of pulmonary embolism (PE) cases present with persistent hypotension, obstructive shock, or cardiac arrest. Given the high short-term mortality, management of high-risk PE cases focuses on immediate reperfusion therapies. Risk stratification of normotensive PE is important to identify patients with an elevated risk of hemodynamic collapse or an elevated risk of major bleeding. Risk stratification for short-term hemodynamic collapse includes assessment of physiological parameters, right heart dysfunction, and identification of comorbidities...

BACKGROUND: Driven by the ability to avoid thrombolytics and provide a one stop procedure with immediate hemodynamic improvement, there has been a dramatic increase in the use of mechanical thrombectomy (MT) devices for the treatment of intermediate-to-high risk pulmonary embolism (PE). This study investigated the incidence and outcomes of cardiovascular collapse during MT procedures and demonstrates the role of ECMO in salvaging patients. METHODS: This was a single center retrospective review of PE patients undergoing MT with the FlowTriever device between 2017 and 2022...

Objective: Acute pulmonary embolism (PE) is potentially fatal. Age, sex, chronic comorbidities, vital signs, and echocardiographic findings are well-known predictive indicators of the short-term mortality. However, the impact of concurrent acute illness on the prognosis is unclear. Materials and Methods: This is a retrospective cohort study using data of hospitalized patients with a diagnosis of acute PE without hemodynamic instability. The outcome measure was 30-day all-cause mortality after diagnosis of acute PE...
