Objective: The aim of this study was to compare the predictive value of two clinical prognostic models, the Spanish score and the simplified Pulmonary Embolism Severity Index (sPESI), in an independent cohort of patients diagnosed of acute symptomatic pulmonary embolism (PE)., Methods: We performed a retrospective analysis of a cohort composed of 1447patients with acute symptomatic PE. The Spanish score and the sPESI were calculated for each patient according to different clinical variables. We assessed the predictive accuracy of these scores for 30-day mortality, and a composite of non fatal recurrent venous thromboembolism and non fatal major bleeding, using Cstatistic, which was obtained by means of logistic regression and ROC curves., Results: Overall, 138 patients died (9.5%) during the first month of follow-up. Both scores showed an excellent predictive value for 30-day all-cause mortality (Cstatistic, 0.72 and 0.74), but the performance was poor for the secondary endpoint (Cstatistic, 0.60 and 0.59). The sPESI classified fewer patients as low risk (32% versus 62%; P<.001). Low-risk patients based on the sPESI had a lower 30-day mortality than those based on the Spanish score (1.1% versus 4.2%), while the 30-day rate of non fatal recurrent VTE or major bleeding was similar (2.2% versus 2.3%)., Conclusions: Both scores provide excellent information to stratify the risk of mortality in patients treated of PE. The usefulness of these models for nonfatal adverse events is questionable. The sPESI identified low-risk patients with PE better than the Spanish score., (Copyright © 2012 SEPAR.

Among patients with pulmonary embolism (PE), various permutations of normal or abnormal cardiac troponin results and normal or abnormal echocardiographic right ventricular function are encountered in clinical practice. We aimed to explore whether there is a true gradient of risk based on troponin and echocardiographic results. This study included normotensive patients with PE from the PROgnosTic valuE of CT scan in hemodynamically stable patients with acute symptomatic pulmonary embolism (PROTECT) study. Patients were categorized as having -Troponin/-Echo, -Troponin/+Echo, +Troponin/-Echo, and +Troponin/+Echo. The primary outcome was 30-day "complicated course," including death from any cause, hemodynamic collapse, or recurrent PE. Secondary outcomes included individual adverse event rates. Of the 834 patients who had echocardiographic and troponin results, 569 patients (68%) had -Troponin/-Echo, 126 patients (15%) had -Troponin/+Echo, 74 patients (8.9%) had +Troponin/-Echo, and 65 patients (7.8%) had +Troponin/+Echo. The incidence of 30-day complicated course was 4.6% in patients with -Troponin/-Echo, 11.9% in patients with -Troponin/+Echo, 13.5% in patients with +Troponin/-Echo, and 16.9% in patients with +Troponin/+Echo (P for trend <0.001). In the subgroup of patients with a high-risk sPESI (i.e., intermediate-risk according to the ESC guidelines) (n = 527), the incidence of 30-day complicated course was 14.9% in patients with -Troponin/+Echo, 18.5% in patients with +Troponin/-Echo, and 17.5% in patients with +Troponin/+Echo (P for trend <0.01). In patiens with PE, there seems to be a risk gradient based on troponin and echocardiographic results. This study did not detect a significant risk difference in those with +Troponin/-Echo compared with -Troponin/+Echo. [ABSTRACT FROM AUTHOR]

For patients who have acute symptomatic pulmonary embolism ( PE ), risk of short-term death and adverse outcomes should drive the initial treatment decisions. Practice guidelines recommend that patients who have a high-risk of PE-related death and adverse outcomes, determined by the presence of haemodynamic instability (i.e., shock or hypotension), should receive systemically administered thrombolytic therapy. Intermediate-high risk patients might benefit from close observation, and some should undergo escalation of therapy beyond standard anticoagulation, particularly if haemodynamic deterioration occurs. Low-risk for adverse outcomes should lead to early hospital discharge or full treatment at home. Validated prognostic tools (i.e., clinical prognostic scoring systems, imaging studies, and cardiac laboratory biomarkers) assist with risk classification of patients who have acute symptomatic PE.

Rapid and accurate risk stratification is critical in determining the optimal treatment strategy for patients with acute pulmonary embolism (PE). Early identification of patients with normal blood pressure and a favorable prognosis (low-risk PE) might select a subset of patients for outpatient treatment, which is associated with reduced cost and improved patient satisfaction, and has been shown to be effective and safe. Alternatively, identification of normotensive patients deemed as having a high risk for PE-related adverse clinical events (intermediate-high-risk PE) might select a subset of patients for close observation and consideration of escalation of therapy. Clinical prognostic scores have been gaining importance in the classification of patients into these categories. They should be derived and validated following strict methodological standards, and their use in clinical practice should be encouraged. [ABSTRACT FROM AUTHOR]

Background: For patients diagnosed with acute pulmonary embolism (PE), the prognostic significance of concomitant right heart thrombi (RHT) lacks clarity.Methods: We performed a meta-analysis of studies that enrolled patients with acute PE to assess the prognostic value of echocardiography-detectable RHT for the primary outcome of short-term all-cause mortality and the secondary outcome of short-term PE-related mortality. Unrestricted searches were conducted of PubMed and Embase from 1980 through January 31, 2016, and used the terms "right heart thrombi," "pulmonary embolism," and "prognos.*" A random effects model was used to pool study results; Begg rank correlation method was used to evaluate for publication bias; and I2 testing was used to assess for heterogeneity.Results: Six of 79 potentially relevant studies met the inclusion criteria (15,220 patients). Overall, 99 of 593 patients with echocardiography-detectable RHT died (16.7% [95% CI, 13.8-19.9]) compared with 639 of 14,627 without RHT (4.4% [95% CI, 4.0-4.7]). RHT had a significant association with short-term all-cause mortality in all patients (OR, 3.0 [95% CI, 2.2 to 4.1]; I2 = 20%) and with PE-related death (three cohorts, 12,955 patients; OR: 4.8 [95% CI, 2.0-11.3; I2 = 76%). Results were consistent for the prospective (two cohorts, 514 patients; OR, 4.8 [95% CI, 1.7-13.6]; I2 = 56%) and the retrospective (four cohorts, 14,706 patients; OR, 2.8 [95% CI, 2.1 to 3.8]; I2 = 0%) studies.Conclusions: In patients diagnosed with acute PE, concomitant RHT were significantly associated with an increased risk of death within 30 days of PE diagnosis.Trial Registry: PROSPERO registry; No.: CRD42016033960; URL: https://www.crd.york.ac.uk/prospero/.

Background: A comprehensive evaluation of temporal trends in the treatment of patients who have DVT may assist with identification of modifiable factors that contribute to short-term outcomes.Methods: We assessed temporal trends in length of hospital stay and use of pharmacological and interventional therapies among 26,695 adults with DVT enrolled in the Registro Informatizado de la Enfermedad TromboEmbólica registry between 2001 and 2014. We also examined temporal trends in risk-adjusted rates of all-cause, pulmonary embolism-related, and bleeding-related death to 30 days after diagnosis.Results: The mean length of hospital stay decreased from 9.0 days in 2001 to 2005 to 7.6 days in 2010 to 2014 (P < .01). For initial DVT treatment, the use of low-molecular-weight heparin decreased from 98% to 90% (P < .01). Direct oral anticoagulants use increased from 0.5% in 2010 to 13.4% in 2014 (P < .001). Risk-adjusted rates of 30-day all-cause mortality decreased from 3.9% in 2001 to 2005 to 2.7% in 2010 to 2014 (adjusted rate ratio per year, 0.84; 95% CI, 0.74-0.96; P < .01). VTE-related mortality showed a nonstatistically significant downward trend (adjusted rate ratio per year, 0.70; 95% CI, 0.44-1.10; P = .13), whereas 30-day bleeding-related mortality significantly decreased from 0.5% in 2001 to 2005 to 0.1% in 2010-2014 (adjusted rate ratio per year, 0.55; 95% CI, 0.40-0.77; P < .01).Conclusions: This international registry-based temporal analysis identified reductions in length of stay for adults hospitalized for DVT. The study also found a decreasing trend in adjusted rates of all-cause and bleeding-related mortality. [ABSTRACT FROM AUTHOR]

Background In patients with acute pulmonary embolism ( PE ), studies have shown an association between coexisting deep vein thrombosis ( DVT ) and short-term prognosis. It is not known whether complete compression ultrasound testing ( CCUS ) improves the risk stratification of their disease beyond the recommended prognostic models. Methods We included patients with normotensive acute symptomatic PE and prognosticated them with the European Society of Cardiology ( ESC ) risk model for PE. Subsequently, we determined the prognostic significance of coexisting DVT in patients with various ESC risk categories. The primary endpoint was a complicated course after the diagnosis of PE, defined as death from any cause, haemodynamic collapse, or adjudicated recurrent PE. Results According to the ESC model, 37% of patients were low-risk, 56% were intermediate-low risk, and 6.7% were intermediate-high risk. CCUS demonstrated coexisting DVT in 375 (44%) patients. Among the 313 patients with low-risk PE, coexisting DVT (46%) did not show a significant increased risk of complicated course (2.8%; 95% confidence interval [ CI ], 0.8%–7.0%), compared with those without DVT (0.6%; 95% CI, 0%–3.2%), ( P  = 0.18). Of the 478 patients with intermediate-low risk PE, a complicated course was 14% and 6.8% for those with and without DVT, respectively ( P  = 0.01). Of the 57 patients that had intermediate-high risk PE, a complicated course occurred in 17% and 18% for those with and without DVT, respectively ( P  = 1.0). Conclusions In normotensive patients with PE, testing for coexisting DVT might improve risk stratification of patients at intermediate-low risk for short-term complications. [ABSTRACT FROM AUTHOR]
