AbstractPrevious studies on the adverse events of acute pulmonary embolism (APE) were mostly limited to single marker, and short follow-up duration, from hospitalization to up to 30 days. We aimed to predict the long-term prognosis of patients with APE by joint assessment of D-dimer, N-Terminal Pro-Brain Natriuretic Peptide (NT-ProBNP), and troponin I (cTnI). Newly diagnosed patients of APE from January 2011 to December 2015 were recruited from three hospitals. Medical information of the patients was collected retrospectively by reviewing medical records. Adverse events (APE recurrence and all-cause mortality) of all enrolled patients were followed up via telephone. D-dimer > 0.50 mg/L, NT-ProBNP > 500 pg/mL, and cTnI > 0.40 ng/mL were defined as the abnormal. Kaplan–Meier curve was used to compare the cumulative survival rate between patients with different numbers of abnormal markers. Cox proportional hazard regression model was used to further test the association between numbers of abnormal markers and long-term prognosis of patients with APE after adjusting for potential confounding. During follow-up, APE recurrence and all-cause mortality happened in 78 (30.1%) patients. The proportion of APE recurrence and death in one abnormal marker, two abnormal markers, and three abnormal markers groups were 7.69%, 28.21%, and 64.10% respectively. Patients with three abnormal markers had the lowest survival rate than those with one or two abnormal markers (Log-rank test, P < 0.001). After adjustment, patients with two or three abnormal markers had a significantly higher risk of the total adverse event compared to those with one abnormal marker. The hazard ratios (95% confidence interval) were 6.27 (3.24, 12.12) and 10.7 (4.1, 28.0), respectively. Separate analyses for APE recurrence and all-cause death found similar results. A joint test of abnormal D-dimer, NT-ProBNP, and cTnI in APE patients could better predict the long-term risk of APE recurrence and all-cause mortality.

BACKGROUND Right heart dysfunction (RHD) is related to adverse outcomes in acute pulmonary embolism (PE). AIM OF THE STUDY To evaluate the relation between RHD, pulmonary clots distribution and biomarkers and prognosis of patients with PE. METHODS We analysed echocardiographic data of 70 patients with diagnosis of PE confirmed by pulmonary computer tomography, hCT. We considered the enddiastolic right/left ventricles ratio > 1 as index of RHD; echocardiographic data were compared with clots distribution in pulmonary vascular tree such as hCT findings and biomarkers. For each patient we calculated the shock index (heart rate/systolic blood pressure ratio, shock defined as ratio ≥ 1). RESULTS Hospital mortality was 8.5%. Mean age of dead patients was significantly higher compared to alive (85.67 vs 71.57 years, p < 0.05). 41% of patients revealed unilateral PE, 59% had bilateral. In 10% of patients main pulmonary artery was interested by clot, 48% of patients had involved one of the main branches, 90% had involved at least one of the lobar branches, 59% one of segmental branches of pulmonary arteries. 52% of patients had RHD. Mortality in RHD patients was 14.8% vs 8% in no RHD, p < 0.05. Mean values of troponin I and D-dimer were significantly higher in RHD patients. Shock index was ≥ 1 in 37.5% of RHD and 20% in no RHD. RHD patients showed significantly higher involvement of main pulmonary artery and its branches and higher bilateral involvement. CONCLUSIONS RHD is related to proximal and bilateral pulmonary clots distribution and troponin I and D-dimer values and poorer prognosis.

Background: We evaluated the diagnostic efficacy of tissue plasminogen activator (tPA), using an enzyme-linked immunosorbent assay (ELISA) and compared it with an ELISA D-dimer (VIDAS D-dimer) in acute pulmonary embolism (PE). Patients and methods: We studied 127 consecutive outpatients with clinically suspected PE. The diagnosis of PE was based on a clinical probability pretest for PE and a strict protocol of imaging studies. A plasma sample to measure the levels of tPA and D-dimer was obtained at enrollment. Diagnostic accuracy for tPA and D-dimer was determined by the area under the receiver operating characteristic (ROC) curve. Sensitivity, specificity, predictive values, and the diagnostic utility of tPA with a cutoff of 8.5 ng/mL and D-dimer with a cutoff of 500 ng/mL, were calculated for PE diagnosis. Results: PE was confirmed in 41 patients (32 %). Areas under ROC curves were 0.86 for D-dimer and 0.71 for tPA. The sensitivity/negative predictive value for D-dimer using a cutoff of 500 ng/mL, and tPA using a cutoff of 8.5 ng/mL, were 95 % (95 % CI, 88–100 %)/95 % (95 % CI, 88–100 %) and 95 % (95 % CI, 88–100 %)/94 %), respectively. The diagnostic utility to exclude PE was 28.3 % (95 % CI, 21–37 %) for D-dimer and 24.4 % (95 % CI, 17–33 %) for tPA. Conclusions: The tPA with a cutoff of 8.5 ng/mL has a high sensitivity and negative predictive value for exclusion of PE, similar to those observed for the VIDAS D-dimer with a cutoff of 500 ng/mL, although the diagnostic utility was slightly higher for the D-dimer.

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.
