RESUMO
BACKGROUND AND AIMS: Home treatment is considered safe in acute pulmonary embolism (PE) patients selected by a validated triage tool (e.g. simplified PE severity index score or Hestia rule), but there is uncertainty regarding the applicability in underrepresented subgroups. The aim was to evaluate the safety of home treatment by performing an individual patient-level data meta-analysis. METHODS: Ten prospective cohort studies or randomized controlled trials were identified in a systematic search, totalling 2694 PE patients treated at home (discharged within 24â h) and identified by a predefined triage tool. The 14- and 30-day incidences of all-cause mortality and adverse events (combined endpoint of recurrent venous thromboembolism, major bleeding, and/or all-cause mortality) were evaluated. The relative risk (RR) for 14- and 30-day mortalities and adverse events is calculated in subgroups using a random effects model. RESULTS: The 14- and 30-day mortalities were 0.11% [95% confidence interval (CI) 0.0-0.24, I2 = 0) and 0.30% (95% CI 0.09-0.51, I2 = 0). The 14- and 30-day incidences of adverse events were 0.56% (95% CI 0.28-0.84, I2 = 0) and 1.2% (95% CI 0.79-1.6, I2 = 0). Cancer was associated with increased 30-day mortality [RR 4.9; 95% prediction interval (PI) 2.7-9.1; I2 = 0]. Pre-existing cardiopulmonary disease, abnormal troponin, and abnormal (N-terminal pro-)B-type natriuretic peptide [(NT-pro)BNP] at presentation were associated with an increased incidence of 14-day adverse events [RR 3.5 (95% PI 1.5-7.9, I2 = 0), 2.5 (95% PI 1.3-4.9, I2 = 0), and 3.9 (95% PI 1.6-9.8, I2 = 0), respectively], but not mortality. At 30 days, cancer, abnormal troponin, and abnormal (NT-pro)BNP were associated with an increased incidence of adverse events [RR 2.7 (95% PI 1.4-5.2, I2 = 0), 2.9 (95% PI 1.5-5.7, I2 = 0), and 3.3 (95% PI 1.6-7.1, I2 = 0), respectively]. CONCLUSIONS: The incidence of adverse events in home-treated PE patients, selected by a validated triage tool, was very low. Patients with cancer had a three- to five-fold higher incidence of adverse events and death. Patients with increased troponin or (NT-pro)BNP had a three-fold higher risk of adverse events, driven by recurrent venous thromboembolism and bleeding.

BACKGROUND: Chronic thromboembolic pulmonary hypertension (CTEPH) is the most severe long-term complication of acute pulmonary embolism (PE). We aimed to evaluate the impact of a symptom screening programme to detect CTEPH in PE survivors. METHODS: This was a multicentre cohort study of patients diagnosed with acute symptomatic PE between January 2017 and December 2018 in 16 centres in Spain. Patients were contacted by phone 2 years after the index PE diagnosis. Those with dyspnoea corresponding to a New York Heart Association (NYHA)/WHO scale≥II, visited the outpatient clinic for echocardiography and further diagnostic tests including right heart catheterisation (RHC). The primary outcome was the new diagnosis of CTEPH confirmed by RHC. RESULTS: Out of 1077 patients with acute PE, 646 were included in the symptom screening. At 2 years, 21.8% (n=141) reported dyspnoea NYHA/WHO scale≥II. Before symptom screening protocol, five patients were diagnosed with CTEPH following routine care. In patients with NYHA/WHO scale≥II, after symptom screening protocol, the echocardiographic probability of pulmonary hypertension (PH) was low, intermediate and high in 76.6% (n=95), 21.8% (n=27) and 1.6% (n=2), respectively. After performing additional diagnostic test in the latter 2 groups, 12 additional CTEPH cases were confirmed. CONCLUSIONS: The implementation of this simple strategy based on symptom evaluation by phone diagnosed more than doubled the number of CTEPH cases. Dedicated follow-up algorithms for PE survivors help diagnosing CTEPH earlier. TRIAL REGISTRATION NUMBER: NCT03953560.

BACKGROUND: Patterns of lung cancer (LC) mortality are important for planning health services and resource management. OBJECTIVES: We aimed to provide updated information (1982-2021) and project (LC) mortality rates in Spain (2022-2046). METHOD: We analysed data from the Spanish National Statistics Institute about mortality in LC (1982-2021), and we made predictions for the period 2022-2046. RESULTS: In 2021, a total of 22,413 people died of LC, and for the period 2042-2046, the projected annual average was 25,549 deaths. In males, age-standardised mortality rates (ASMR) (overall) after an initial period of increase (1982-1996, 2.2%) declined until 2021 (-1.4% per year), and this decline is expected to continue in the future (-1.9% per year during the period 2022-2046), although the projected decline is slightly higher (-2.0% during the period 2022-2046). In men, ASMR (all ages) after an initial period of increase (1982-1996, 2.2%) declined until 2021 (-1.4% per year), and this decline is expected to continue in the future during the period 2022-2046. In women, both the overall and truncated rates (35-64) increase during the period 1982-2021 (4.1% and 6.0% per year, respectively), and projected rates showed that both will decrease during the period 2022-2046, although more markedly in the truncated rates (-1.9% per year) than in the overall rates (-0.5% per year). CONCLUSIONS: Our projections show the magnitude of a steady upward trend in LC mortality among women in Spain that appears to be beginning to reverse from the current decade (similar to that observed for incidence).

BACKGROUND: The length of hospital stay (LOS) for acute pulmonary embolism (PE) varies considerably. Whether the upfront use of a PE prognostic assessment and management pathway is effective in reducing the LOS remains unknown. METHODS: We conducted a randomised controlled trial of adults hospitalised for acute PE: patients were assigned either to a prognostic assessment and management pathway involving risk stratification followed by predefined criteria for mobilisation and discharge (intervention group) or to usual care (control group). The primary end-point was LOS. The secondary end-points were the cost of prognostic tests and of hospitalisation, and 30-day clinical outcomes. RESULTS: Of 500 patients who underwent randomisation, 498 were included in the modified intention-to-treat analysis. The median LOS was 4.0â days (interquartile range (IQR) 3.7-4.2â days) in the intervention group and 6.1â days (IQR 5.7-6.5â days) in the control group (p<0.001). The mean total cost of prognostic tests was EUR 174.76 in the intervention group, compared with EUR 233.12 in the control group (mean difference EUR -58.37, 95% CI EUR -84.34- to -32.40). The mean total hospitalisation cost per patient was EUR 2085.66 in the intervention group, compared with EUR 3232.97 in the control group (mean difference EUR -1147.31, 95% CI EUR -1414.97- to -879.65). No significant differences were observed in 30-day readmission (4.0% versus 4.8%), all-cause mortality (2.4% versus 2.0%) or PE-related mortality (0.8% versus 1.2%) rates. CONCLUSIONS: The use of a prognostic assessment and management pathway was effective in reducing the LOS for acute PE.

OBJECTIVES: We explored the variations in use of imaging modalities for confirming pulmonary embolism (PE) according to the trimester of pregnancy. METHODS: We included all pregnant patients with confirmed acute PE from RIETE, a prospective registry of patients with PE (03/2001-02/2020). Imaging modalities included computed tomography pulmonary angiography (CTPA), ventilation-perfusion (V/Q) scan, or presence of signs of acute PE along with imaging-confirmed proximal deep vein thrombosis (pDVT) without pulmonary vascular imaging. We compared the imaging modalities to postpartum patients with PE, and other non-pregnant women with PE. RESULTS: There were 157 pregnant patients (age: 32.7 ± 0.5), 228 postpartum patients (age: 33.9 ± 0.5), and 23,937 non-pregnant non-postpartum women (age: 69.5 ± 0.1). CTPA was the most common modality for confirming PE, from 55.7% in first trimester to 58.3% in second trimester, and 70.0% in third trimester. From first trimester to third trimester, V/Q scanning was used in 21.3%, 16.7%, and 18.3% of cases, respectively. Confirmed pDVT along with the presence of signs/symptoms of PE was the confirmatory modality for PE in 21.3% of patients in first trimester, 19.4% in second trimester, and 6.7% in third trimester. The proportion of postpartum patients confirmed with CTPA (85.5%) was comparable to that of non-pregnant non-postpartum women (83.2%). From the first trimester of pregnancy to postpartum period, there was a linear increase in the proportion of patients with PE diagnosed with CTPA (p = 0.039). CONCLUSION: CTPA was the primary modality for confirming PE in all trimesters of pregnancy, although its proportional use was higher in later stages of pregnancy. KEY POINTS: ⢠Computed tomography pulmonary angiography (CTPA) was the primary modality of diagnosis in all trimesters of pregnancy among patients with confirmed pulmonary embolism, even in the first trimester. ⢠From the first trimester of pregnancy to postpartum period, there was a linear increase in the proportion of patients with pulmonary embolism who were diagnosed based on CTPA. ⢠In the postpartum period, use of CTPA as the modality to confirm pulmonary embolism was comparable to non-pregnant patients.

Importance: Active search for pulmonary embolism (PE) may improve outcomes in patients hospitalized for exacerbations of chronic obstructive pulmonary disease (COPD). Objective: To compare usual care plus an active strategy for diagnosing PE with usual care alone in patients hospitalized for COPD exacerbation. Design, Setting, and Participants: Randomized clinical trial conducted across 18 hospitals in Spain. A total of 746 patients were randomized from September 2014 to July 2020 (final follow-up was November 2020). Interventions: Usual care plus an active strategy for diagnosing PE (D-dimer testing and, if positive, computed tomography pulmonary angiogram) (n = 370) vs usual care (n = 367). Main Outcomes and Measures: The primary outcome was a composite of nonfatal symptomatic venous thromboembolism (VTE), readmission for COPD, or death within 90 days after randomization. There were 4 secondary outcomes, including nonfatal new or recurrent VTE, readmission for COPD, and death from any cause within 90 days. Adverse events were also collected. Results: Among the 746 patients who were randomized, 737 (98.8%) completed the trial (mean age, 70 years; 195 [26%] women). The primary outcome occurred in 110 patients (29.7%) in the intervention group and 107 patients (29.2%) in the control group (absolute risk difference, 0.5% [95% CI, -6.2% to 7.3%]; relative risk, 1.02 [95% CI, 0.82-1.28]; P = .86). Nonfatal new or recurrent VTE was not significantly different in the 2 groups (0.5% vs 2.5%; risk difference, -2.0% [95% CI, -4.3% to 0.1%]). By day 90, a total of 94 patients (25.4%) in the intervention group and 84 (22.9%) in the control group had been readmitted for exacerbation of COPD (risk difference, 2.5% [95% CI, -3.9% to 8.9%]). Death from any cause occurred in 23 patients (6.2%) in the intervention group and 29 (7.9%) in the control group (risk difference, -1.7% [95% CI, -5.7% to 2.3%]). Major bleeding occurred in 3 patients (0.8%) in the intervention group and 3 patients (0.8%) in the control group (risk difference, 0% [95% CI, -1.9% to 1.8%]; P = .99). Conclusions and Relevance: Among patients hospitalized for an exacerbation of COPD, the addition of an active strategy for the diagnosis of PE to usual care, compared with usual care alone, did not significantly improve a composite health outcome. The study may not have had adequate power to assess individual components of the composite outcome. Trial Registration: ClinicalTrials.gov Identifier: NCT02238639.

The study aimed to identify predictors of overall 30-day mortality in cancer patients with pulmonary embolism including suspected pulmonary embolism (SPE) and unsuspected pulmonary embolism (UPE) events. Secondary outcomes included 30- and 90-day major bleeding and venous thromboembolism (VTE) recurrence.The study cohort included 1033 consecutive patients with pulmonary embolism from the multicentre observational ambispective EPIPHANY study (March 2006-October 2014). A subgroup of 497 patients prospectively assessed for the study were subclassified into three work-up scenarios (SPE, truly asymptomatic UPE and UPE with symptoms) to assess outcomes.The overall 30-day mortality rate was 14%. The following variables were associated with the overall 30-day mortality on multivariate analysis: VTE history, upper gastrointestinal cancers, metastatic disease, cancer progression, performance status, arterial hypotension <100â mmHg, heart rate >110â beats·min-1, basal oxygen saturation <90% and SPE (versus overall UPE).The overall 30-day mortality was significantly lower in patients with truly asymptomatic UPE events (3%) compared with those with UPE-S (20%) and SPE (21%) (p<0.0001). Thirty- and 90-day VTE recurrence and major bleeding rates were similar in all the groups.In conclusion, variables associated with the severity of cancer and pulmonary embolism were associated with short-term mortality. Our findings may help to develop pulmonary embolism risk-assessment models in this setting.

This study aimed to determine the effect of an evidence-based clinical decision support (CDS) algorithm on the use and yield of CT pulmonary angiography (CTPA) and on outcomes of patients evaluated in the emergency department (ED) for suspected PE. The study included 1363 consecutive patients evaluated for suspected PE in an ED during 12â months before and 12â months after initiation of CDS use. Introduction of CDS was associated with decreased CTPA use (55% vs 49%; absolute difference (AD), 6.3%; 95% CI 1.0% to 11.6%; p=0.02). The use of CDS was associated with fewer symptomatic venous thromboembolic events during follow-up in patients with an initial negative diagnostic evaluation for PE (0.7% vs 3.2%; AD 2.5%; 95% CI 0.9% to 4.6%; p<0.01).

BACKGROUND: In patients with acute pulmonary embolism (PE), rapid and accurate risk assessment is paramount in selecting the appropriate treatment strategy. The prognostic value of right ventricular dysfunction (RVD) assessed by multidetector CT (MDCT) in normotensive patients with PE has lacked adequate validation. METHODS: The study defined MDCT-assessed RVD as a ratio of the RV to the left ventricle short axis diameter greater than 0.9. Outcomes assessed through 30 days after the diagnosis of PE included all-cause mortality and 'complicated course', which consisted of death from any cause, haemodynamic collapse or recurrent PE. RESULTS: MDCT detected RVD in 533 (63%) of the 848 enrolled patients. Those with RVD on MDCT more frequently had echocardiographic RVD (31%) than those without RVD on MDCT (9.2%) (p<0.001). Patients with RVD on MDCT had significantly higher brain natriuretic peptide (269±447 vs 180±457 pg/ml, p<0.001) and troponin (0.10±0.43 vs 0.03±0.24 ng/ml, p=0.001) levels in comparison with those without RVD on MDCT. During follow-up, death occurred in 25 patients with and in 13 patients without RVD on MDCT (4.7% vs 4.3%; p=0.93). Those with and those without RVD on MDCT had a similar frequency of complicated course (3.9% vs 2.3%; p=0.30). CONCLUSIONS: The PROgnosTic valuE of CT study showed a relationship between RVD assessed by MDCT and other markers of cardiac dysfunction around the time of PE diagnosis, but did not demonstrate an association between MDCT-RVD and prognosis.

The aim of our study was to analyse changes in the incidence, diagnostic procedures, comorbidity, length of hospital stay, costs and in-hospital mortality of patients hospitalised for pulmonary embolism in Spain over a 10-year period. We included all patients who were hospitalised for pulmonary embolism (ICD-9-CM codes 415.11 and 415.19) as the primary diagnosis between 2002 and 2011. Data were collected from the National Hospital Discharge Database, covering the entire Spanish population. 115 671 patients were admitted. The overall crude incidence increased from 20.44 per 100 000 inhabitants in 2002 to 32.69 in 2011 (p<0.05). In 2002, 13.3% of patients had a Charlson comorbidity index>2, and in 2011 the prevalence increased to 20.8% (p<0.05). Mean length of hospital stay was 12.7 days in 2002 and decreased to 9.99 in 2011 (p<0.05). During the study period, mean cost per patient increased from 3915 to 4372 (p<0.05). In-hospital mortality decreased from 12.9% in 2002 to 8.32% in 2011 (p<0.05). The increase in the use of computed tomographic pulmonary angiography over time was associated with increased incidence and lower mortality. Our results revealed an increase in the incidence of hospitalised pulmonary embolism patients from 2002 to 2011 with concomitant increase in comorbidities and cost. However, length of hospital stay and in-hospital mortality decreased.

The purpose of this prospective cohort study was to assess the feasibility of outpatient treatment in patients with cancer and objectively confirmed pulmonary embolism (PE), and to compare the performance of the different prognostic scales available in this setting. Patients were selected for outpatient management according to a set of exclusion criteria. Outcomes at 30 and 90 days of follow-up included thromboembolic recurrences, major bleeding, and all-cause death. The performance of 4 prognostic scales (Pulmonary Embolism Severity Index, Geneva Prognostic Score, POMPE-C, and Registro Informatizado de Enfermedad Tromboembólica [RIETE registry]) was evaluated. Of 138 patients, 62 (45%) were managed as outpatients. Incidental PE constituted 47% of the sample. Most patients treated at home had an incidentally detected PE (89%). The rate of recurrence and major bleeding events was similar in both groups. Mortality rates were higher for patients admitted to the hospital compared with outpatients at 30 days (18% vs 3%; P=.06) and 90 days (34% vs 10%; P=.001) of follow-up. None of the patients selected for home treatment required further admission because of PE complications. None of the prognostic models developed for symptomatic PE was significantly associated with 30-day mortality. Improved survival outcomes were observed in incidentally detected PEs compared with acute symptomatic events (overall mortality rates, 3.2% vs 18.4%; P=.006). A large proportion of patients with cancer and PE may be safely treated as outpatients, especially those with incidental PE. Cancer-specific prognostic scales including incidental PE should be developed for the optimal management of PE in this setting.

Importance: High-sensitivity troponin tests can detect even milder cardiac troponin elevations in plasma, beyond the threshold of conventional troponin tests. Whether detection of low-grade cardiac troponin elevation is associated with outcomes of patients with hemodynamically stable pulmonary embolism (PE) and helps with risk stratification is unknown. Objective: To determine the association between high-sensitivity cardiac troponin I (hs-cTnI) compared with conventional cardiac troponin I (cTnI) and PE risk designations according to the European Society of Cardiology (ESC) 2019 classification scheme and clinical outcomes in patients with hemodynamically stable PE. Design, Setting, and Participants: This is a post hoc analysis of data from the prospective Prognostic Value of Computed Tomography (PROTECT) multicenter cohort study enrolling patients from 12 hospital emergency departments in Spain. In this analysis, cTnI and hs-cTnI were compared with respect to ESC risk designation, and the association between troponin values and a complicated course after PE diagnosis was evaluated. Of 848 patients enrolled in PROTECT, 834 (98.3%) had hsTnI and cTnI values available and were included in the present analysis. Data were analyzed from May to December 2022. Exposures: Troponin blood testing with cTnI (threshold of >0.05 ng/mL) vs hs-cTnI (threshold of >0.029 ng/mL) assays at the time of PE diagnosis. Main Outcomes: Complicated course, defined as hemodynamic collapse, recurrent PE, or all-cause death, within 30 days after PE. Results: Of 834 patients (mean [SEM] age, 67.5 [0.6] years; 424 [50.8%] female), 139 (16.7%) had elevated cTnI and 264 (31.7%) elevated hs-TnI, respectively. During follow-up, 62 patients (7.4%; 95% CI, 5.7-9.4) had a complicated course. Analyzing troponin elevation as a binary variable, elevated cTnI (odds ratio [OR], 2.84; 95% CI, 1.62-4.98) but not hs-cTnI (OR, 1.12; 95% CI, 0.65-1.93) was associated with increased odds of a complicated course. Of 125 patients who had elevated hs-cTnI but normal cTnI, none (0; 95% CI, 0.0-2.9) developed a complicated course. Using the 2019 ESC risk stratification scheme, hs-TnI classified fewer patients as low risk compared with cTnI. Among 78 patients designated as ESC low risk when using cTnI but not with hsTnI, none (0; 95% CI, 0.0-4.6) had a complicated course. Conclusions and Relevance: In this study of patients with hemodynamically stable PE, hs-cTnI identified modest elevations in cardiac troponin levels. However, the results did not provide additive clinical value compared with cTnI. These findings suggest that use of hs-cTnI may result in overestimation of the risk in patients with stable PE.

BACKGROUND: Various risk assessment tools have been proposed to identify stable patients with acute pulmonary embolism (PE) who are at high risk of early adverse outcome (i.e., intermediate-high risk). METHODS: We evaluated the ability of the 2019 ESC, Bova, modified FAST and PEITHO-3 models for predicting a 30-day complicated course (death, haemodynamic collapse, and/or recurrent PE) in a cohort of 848 stable patients with acute PE. We also tested whether replacement of echocardiographic right ventricle (RV) dysfunction by computed tomographic (CT) RV enlargement provides comparable prognostic information for identifying these patients. RESULTS: A complicated course occurred in 63 (7.4 %) of the 848 patients with PE during the first month of follow-up. The proportion of patients designated as having intermediate-high risk PE was 6.7 % with the ESC model, 4.4 % with the Bova score, 15.7 % with the FAST score, and 5.2 % with the PEITHO-3 model. However, among patients identified as intermediate-high risk, the 30-day complicated course rate was higher with the Bova score (21.6 %) than with the ESC model (17.5 %), the PEITHO-3 model (15.9 %), or the modified FAST score (14.3 %). When echocardiographic RV dysfunction was replaced by CT RV enlargement in the models, the proportion of patients classified as having intermediate-high risk PE and the rate of an adverse outcome among them slightly increased. CONCLUSIONS: The Bova score might identify patients with intermediate-high risk PE slightly better than the ESC, PEITHO-3, and modified FAST score. When echocardiography is not readily available, CT-assessed RV enlargement might be used for identifying intermediate-high risk PE. CLINICALTRIALS: gov number: NCT02238639.

INTRODUCTION: Chronic thromboembolic pulmonary hypertension (CTEPH) is a long-term sequel to pulmonary embolism (PE) whose incidence varies according to different published studies. We have carried out this study to determine its incidence within 2 years after index pulmonary embolism and to study limitations to an early diagnosis. MATERIAL AND METHODS: OSIRIS is a multicentre, longitudinal cohort study. Patients were followed for 3, 6, 12, and 24 months after pulmonary embolism using a structured three-step algorithm. A physician-centered questionnaire at least one positive response in a screening proceeded to the second step, transthoracic echocardiography. The third step consisted of ventilation/perfusion lung scintigraphy and right heart catheterisation. A transthoracic echocardiography was performed in patients without positive response in the screening questionnaire after 2 years. CTEPH diagnosis required haemodynamic confirmation by right heart catheterisation and mismatched perfusion defects on lung scintigraphy. RESULTS: A total of 1191 patients were enrolled in 18 Spanish hospitals. Cumulative CTEPH incidence after 2-years PE was: 2.49 % (95 % CI: 1.68-3.56) and the incidence rate of CTEPH was 1.1 cases per 1000 person-months (95 % CI: 0.725; 1.60). The CTEPH algorithm presented a lack of adherence of 29 %; patient and physician preferences posed barriers to the triage algorithm The screening questionnaire, in patients who completed the follow-up, shows a specificity of 91.3 % (89.0-93.2 %) and negative predictive value of 99.4 % (98.4-99.8 %)..

Background: The optimal duration of anticoagulation in patients with active cancer and venous thromboembolism (VTE) is unknown. Current clinical guidelines advocate anticoagulant therapy for 3-6 months and to continue anticoagulant therapy for as long as the cancer is active. However, an adequate systematic review on the rate of recurrent VTE after discontinuation of anticoagulant therapy has not been performed. Methods: For this systemic review and meta-analysis, we searched Embase.com, Medline (Ovid), Web of Science, Cochrane Library, and Google Scholar, from database inception to February 16, 2023, for studies on anticoagulant therapy in patients with cancer and the recurrence of venous thromboembolism after discontinuation of this therapy. We included randomised controlled trials and cohort studies published in English that reported on patients who met the following: cancer and a first VTE, completed at least 3 months of anticoagulant therapy, were followed after discontinuation of anticoagulant therapy, and with symptomatic recurrent VTE as an outcome during follow-up. Study-level data were requested from study authors. The primary outcome was the rate of recurrent VTE after discontinuation of anticoagulant therapy. A Bayesian random-effects meta-analysis was used to estimate the rate of recurrent VTE per 100 person-years for the pooled studies at different time intervals after discontinuation of anticoagulation therapy. We also calculated the cumulative VTE recurrence rate at different time intervals. Forest plots were mapped and the results were summarized by the median and 95% credible interval (CIs). This study was registered with PROSPERO, CRD42021249060. Findings: Of 3856 studies identified in our search, 33 studies were identified for inclusion. After requesting study-level data, 14 studies involving 1922 patients with cancer-associated thrombosis were included. The pooled rate of recurrent VTE per 100 person-years after discontinuation of anticoagulant therapy was 14.6 events (95% credible interval 6.5-22.8) in the first three months, decreasing to 1.1 events (95% CI 0.3-2.1) in year 2-3, and 2.2 events (95% CI 0.0-4.4) in year 3-5 after discontinuation of anticoagulant therapy. The cumulative VTE recurrence rate was 28.3% (95% CI 15.6-39.6%) at 1 year; 31.1% (95% CI 16.5-43.8%) at 2 years; 31.9% (95% CI 16.8-45.0%) at 3 years; and 35.0% (95% CI 16.8-47.4%) at 5 years after discontinuation of anticoagulant therapy. Interpretation: This meta-analysis demonstrates a high rate of recurrent VTE over time after discontinuation of anticoagulant therapy in patients with cancer-associated thrombosis. Our results support the current clinical guidelines to continue anticoagulant therapy in patients with active cancer. Funding: Erasmus MC.
RESUMO
The PROTECT study is designed to assess the prognostic significance of multidetector computed tomography (MDCT) findings in normotensive outpatients with pulmonary embolism (PE). MDCT assesses right ventricular dysfunction (RVD) by measuring the ratio of the right-to-left ventricular short axis diameters. The study uses 30-day all-cause mortality as the primary outcome. The study determined inter- and intraobserver reproducibility of CT findings of RVD. According to the local radiologists' measurements, 44 % of patients (42/96) showed RVD (defined as a ratio of the RV to the LV short axis greater than 0.9). The intraclass correlation was good (0.773, CI 95 %, 0.678-0.842). For interobserver reproducibility, the weighted kappa measurement was 0.730. Intraobserver reproducibility was very good (0.932, 95 % CI, 0.880-0.962). The PROTECT study is designed to show the prognostic significance of MDCT for PE. Inter- and intraobserver agreement of interpretation of RVD were good.

BACKGROUND: Among patients hospitalized for an exacerbation of chronic obstructive pulmonary disease (COPD), the SLICE trial showed that the addition of an active diagnostic strategy for pulmonary embolism (PE) to usual care compared with usual care alone did not improve a composite set of health outcomes. The objective of this subanalysis was to determine the frequency and prognostic significance of findings on computed tomography pulmonary angiogram (CTPA) supporting an alternative diagnosis to PE. METHODS: We analyzed all patients randomized to the intervention in the SLICE trial who received a CTPA that did not show PE. We used multivariable logistic regression to assess the independent association between findings supporting an alternative diagnosis to PE and a composite of readmission for COPD or death within 90 days after randomization. RESULTS: Among the 746 patients who were randomized, this subanalysis included 175 patients in the intervention group who received a CTPA that did not show PE. Eighty-four (48.0%) patients had acute bronchial infection, 13 (7.4%) had lung cancer, 10 (5.7%) had congestive heart failure, 8 (4.6%), 18 (10.3%) had other diagnoses, and 42 (24.0%) had a normal CTPA. In multivariable analysis, findings supporting an alternative diagnosis to PE were not significantly associated with the primary outcome (odds ratio: 0.64; 95% confidence interval: 0.30-1.38; P=0.26). CONCLUSIONS: Among patients hospitalized for an exacerbation of COPD, CTPA identified an alternative diagnosis in 76% of the patients. However, specific management of these patients was not associated with improved outcomes within 90 days after randomization.

The most appropriate duration of anticoagulant treatment for cancer-associated venous thromboembolism (CAT) remains unclear. We have conducted a prospective multicenter study in CAT patients with more than 6 months of anticoagulant treatment to predict the risk of venous thromboembolism (VTE) recurrence after anticoagulation discontinuation. Blood samples were obtained when patients stopped the anticoagulation, at 21 days and at 90 days. In each sample we assessed different coagulation-related biomarkers: D-dimer (DD), high-sensitivity C-reactive protein (hs-CRP), P-selectin (PS), phospholipids, soluble tissue factor, factor VIII and the thrombin generation test. It was evaluated 325 CAT patients and 166 patients were included in the study, mean age 64 ± 17 years. VTE recurrence until 6 months after stopping anticoagulation treatment was 9.87% [95% confidence interval (CI): 6−15]. The biomarkers sub-distribution hazard ratios were 6.32 for ratio DD basal/DD 21 days > 2 (95% CI: 1.82−21.90), 6.36 for hs-CRP > 4.5 (95% CI: 1.73−23.40) and 5.58 for PS > 40 (95% CI: 1.46−21.30) after 21 days of stopping anticoagulation. This is the first study that has identified the DD ratio, hs-CRP and PS as potential biomarkers of VTE recurrence in cancer patients after the discontinuation of anticoagulation treatment. A risk-adapted strategy may allow the identification of the optimal time to withdraw the anticoagulation in each CAT patient.
RESUMO
RATIONALE: Concomitant deep vein thrombosis (DVT) in patients with acute pulmonary embolism (PE) has an uncertain prognostic significance. OBJECTIVES: In a cohort of patients with PE, this study compared the risk of death in those with and those without concomitant DVT. METHODS: We conducted a prospective cohort study of outpatients diagnosed with a first episode of acute symptomatic PE. Patients underwent bilateral lower extremity venous compression ultrasonography to assess for concomitant DVT. MEASUREMENTS AND MAIN RESULTS: The primary study outcome, all-cause mortality, and the secondary outcome of PE-specific mortality were assessed during the 3 months of follow-up after PE diagnosis. Multivariate Cox proportional hazards regression was done to adjust for significant covariates. Of 707 patients diagnosed with PE, 51.2% (362 of 707) had concomitant DVT and 10.9% (77 of 707) died during follow-up. Patients with concomitant DVT had an increased all-cause mortality (adjusted hazard ratio [HR], 2.05; 95% confidence interval [CI], 1.24 to 3.38; P = 0.005) and PE-specific mortality (adjusted HR, 4.25; 95% CI, 1.61 to 11.25; P = 0.04) compared with those without concomitant DVT. In an external validation cohort of 4,476 patients with acute PE enrolled in the international multicenter RIETE Registry, concomitant DVT remained a significant predictor of all-cause (adjusted HR, 1.66; 95% CI, 1.28 to 2.15; P < 0.001) and PE-specific mortality (adjusted HR, 2.01; 95% CI, 1.18 to 3.44; P = 0.01). CONCLUSIONS: In patients with a first episode of acute symptomatic PE, the presence of concomitant DVT is an independent predictor of death in the ensuing 3 months after diagnosis. Assessment of the thrombotic burden should assist with risk stratification of patients with acute PE.
