Background: Assessment of bleeding risk in patients with pulmonary embolism (PE) is challenging. Recently, the VTE-BLEED score was shown to predict major bleeding. Therefore, we aimed to investigate the VTE-BLEED score and assess the prognostic impact of major bleeding in a real-world cohort of PE patients. Methods: Consecutive PE patients included in a prospective single-center cohort study between 09/2008 and 11/2016 were eligible for analysis; patients treated with thrombolysis were excluded. The VTE-BLEED was calculated post-hoc; in-hospital major bleeding was defined using the ISTH definition. Results: Overall, 522 patients (median age 69, IQR 56-78 years; 53% female) were included in the present analysis; major bleeding occurred in 18 (3.5%) patients. A VTE-BLEED score ≥2 points identified patients at high-risk for major bleeding (OR 3.7, 95% CI 1.1-13.0, sensitivity 83%, specificity 42%). Additionally, a GFR b30 ml/min/1.73 m 2 (OR 6.0, 95% CI 1.8-19.8) and previous surgery (OR 3.6, 95% CI 1.4-9.3) were associated with major bleeding. A less frequent use of unfractionated heparin as initial treatment was associated with a decrease of major bleeding over time. Major bleeding was identified as strong predictor of inhospital (OR 7.7, 95% CI 2.3-25.8) and 1-year mortality (HR 3.6, 95% CI 2.0-6.6), especially in normotensive patients (OR 12.1, 95% CI 3.5-43.0 and HR 6.0, 95% CI 2.9-12.6, respectively). Conclusions: In a real-world cohort, the VTE-BLEED score identified PE patients at risk for in-hospital major bleeding. However, for assessment of bleeding risk, renal function and previous surgery should be considered. Major bleeding emerged as strong predictor of in-hospital and 1-year mortality.
Background Real-world data on the impact of advances in risk-adjusted management on the outcome of patients with pulmonary embolism (PE) are limited. Methods To investigate temporal trends in treatment, in-hospital adverse outcomes and 1-year mortality, we analysed data from 605 patients [median age, 70 years (IQR 56-77) years, 53% female] consecutively enrolled in a single-centre registry between 09/2008 and 08/2016. Results Over the 8-year period, more patients were classified to lower risk classes according to the European Society of Cardiology (ESC) 2014 guideline algorithm while the number of high-risk patients with out-of-hospital cardiac arrest (OHCA) increased. Although patients with OHCA had an exceptionally high in-hospital mortality rate of 59.3%, the rate of PE-related in-hospital adverse outcomes (12.2%) in the overall patient cohort remained stable over time. The rate of reperfusion treatment was 9.6% and tended to increase in high-risk patients. We observed a decrease in the median duration of in-hospital stay from 10 (IQR 6-14) to 7 (IQR 4-15) days, an increase of patients discharged early from 2.1 to 12.2% and an increase in the use of non-vitamin K-dependent oral anticoagulants (NOACs) from 12.6 to 57.2% in the last 2 years (09/2014-08/2016) compared to first 6 years (09/2008-08/2014). The 1-year mortality rate (16.9%) remained stable throughout the study period. Conclusion In-hospital adverse outcomes and 1-year mortality remained stable despite more patients with OHCA, shorter in-hospital stays, more patients discharged early and a more frequent NOAC use.
BackgroundAlthough prior studies indicate a high prevalence of atrial fibrillation (AF) in patients with pulmonary embolism (PE), the exact prevalence and prognostic impact are unknown.MethodsWe aimed to investigate the prevalence, risk factors and prognostic impact of AF on risk stratification, in‐hospital adverse outcomes and mortality in 528 consecutive PE patients enrolled in a single‐centre registry between 09/2008 and 09/2017.ResultsOverall, 52 patients (9.8%) had known AF and 57 (10.8%) presented with AF on admission; of those, 34 (59.6%) were newly diagnosed with AF. Compared to patients with no AF, overt hyperthyroidism was associated with newly diagnosed AF (OR 7.89 [2.99–20.86]), whilst cardiovascular risk comorbidities were more frequently observed in patients with known AF. Patients with AF on admission had more comorbidities, presented more frequently with tachycardia and elevated cardiac biomarkers and were hence stratified to higher risk classes. However, AF on admission had no impact on in‐hospital adverse outcome (8.3%) and in‐hospital mortality (4.5%). In multivariate logistic regression analyses corrected for AF on admission, NT‐proBNP and troponin elevation as well as higher risk classes in risk assessment models remained independent predictors of an in‐hospital adverse outcome.ConclusionAtrial fibrillation is a frequent finding in PE, affecting more than 10% of patients. However, AF was not associated with a higher risk of in‐hospital adverse outcomes and did not affect the prognostic performance of risk assessment strategies. Thus, our data support the use of risk stratification tools for patients with acute PE irrespective of the heart rhythm on admission.
AimsRight atrial (RA) dilation and stretch provide prognostic information in patients with cardiovascular diseases. We investigated the prevalence, confounding factors and prognostic relevance of RA dilation in patients with pulmonary embolism (PE).MethodsOverall, 609 PE patients were consecutively included in a prospective single-centre registry between 09/2008 and 08/2017. Volumetric measurements of heart chambers were performed on routine non-electrocardiographic-gated computed tomography (CT) and plasma concentrations of mid-regional pro-atrial natriuretic peptide (MR-proANP) measured on admission. An in-hospital adverse outcome was defined as PE-related death, cardiopulmonary resuscitation, mechanical ventilation or catecholamine administration.ResultsPatients with an adverse outcome (11.2%) had larger RA volumes (median 120 [IQR 84–152] versus 102 [78–134] mL; p=0.013), RA/LA volume ratios (1.7 [1.2–2.4] versus 1.3 [1.1–1.7]; p<0.001) and MR-proANP levels (282 [157–481] versus 129 [64–238] pmol·L−1; p<0.001) compared to patients with a favourable outcome. Overall, 499 patients (81.9%) had a RA/LA volume ratio ≥1.0 and a calculated cut-off value of 1.8 (AUC 0.64 [95%CI 0.56–0.71]) predicted an adverse outcome, both in unselected (OR 3.1, 95%CI 1.9–5.2) and normotensive patients (OR 2.7, 95%CI 1.3–5.6). MR-proANP ≥120 pmol·L−1 was identified as an independent predictor of an adverse outcome, both in unselected (OR 4.6, 95%CI 2.3–9.3) and normotensive patients (OR 5.1, 95%CI 1.5–17.6).ConclusionsRA dilation is a frequent finding in patients with PE. However, the prognostic performance of RA dilation appears inferior compared to established risk stratification markers. MR-proANP predicted an in-hospital adverse outcome, both in unselected and normotensive PE patients, integrating different prognostic relevant information from comorbidities.
