Abstract
BACKGROUND Sudden cardiac death occurs in ∼220,000 U.S. adults annually, the majority of whom have no prior symptoms or cardiovascular diagnosis. Rare pathogenic DNA variants in any of 49 genes can pre-dispose to 4 important causes of sudden cardiac death: cardiomyopathy, coronary artery disease, inherited arrhythmia syndrome, and aortopathy or aortic dissection. OBJECTIVES This study assessed the prevalence of rare pathogenic variants in sudden cardiac death cases versus controls, and the prevalence and clinical importance of such mutations in an asymptomatic adult population. METHODS The authors performed whole-exome sequencing in a case-control cohort of 600 adult-onset sudden cardiac death cases and 600 matched controls from 106,098 participants of 6 prospective cohort studies. Observed DNA sequence variants in any of 49 genes with known association to cardiovascular disease were classified as pathogenic or likely pathogenic by a clinical laboratory geneticist blinded to case status. In an independent population of 4,525 asymptomatic adult participants of a prospective cohort study, the authors performed whole-genome sequencing and determined the prevalence of pathogenic or likely pathogenic variants and prospective association with cardiovascular death. RESULTS Among the 1,200 sudden cardiac death cases and controls, the authors identified 5,178 genetic variants and classified 14 as pathogenic or likely pathogenic. These 14 variants were present in 15 individuals, all of whom had experienced sudden cardiac death-corresponding to a pathogenic variant prevalence of 2.5% in cases and 0% in controls (p < 0.0001). Among the 4,525 participants of the prospective cohort study, 41 (0.9%) carried a pathogenic or likely pathogenic variant and these individuals had 3.24-fold higher risk of cardiovascular death over a median follow-up of 14.3 years (p = 0.02). CONCLUSIONS Gene sequencing identifies a pathogenic or likely pathogenic variant in a small but potentially important subset of adults experiencing sudden cardiac death; these variants are present in ∼1% of asymptomatic adults.

Abstract
Venous thromboembolism (VTE) is a significant contributor to morbidity and mortality. To advance our understanding of the biology contributing to VTE, we conducted a genome-wide association study (GWAS) of VTE and a transcriptome-wide association study (TWAS) based on imputed gene expression from whole blood and liver. We meta-analyzed GWAS data from 18 studies for 30 234 VTE cases and 172 122 controls and assessed the association between 12 923 718 genetic variants and VTE. We generated variant prediction scores of gene expression from whole blood and liver tissue and assessed them for association with VTE. Mendelian randomization analyses were conducted for traits genetically associated with novel VTE loci. We identified 34 independent genetic signals for VTE risk from GWAS meta-analysis, of which 14 are newly reported associations. This included 11 newly associated genetic loci (C1orf198, PLEK, OSMR-AS1, NUGGC/SCARA5, GRK5, MPHOSPH9, ARID4A, PLCG2, SMG6, EIF5A, and STX10) of which 6 replicated, and 3 new independent signals in 3 known genes. Further, TWAS identified 5 additional genetic loci with imputed gene expression levels differing between cases and controls in whole blood (SH2B3, SPSB1, RP11-747H7.3, RP4-737E23.2) and in liver (ERAP1). At some GWAS loci, we found suggestive evidence that the VTE association signal for novel and previously known regions colocalized with expression quantitative trait locus signals. Mendelian randomization analyses suggested that blood traits may contribute to the underlying risk of VTE. To conclude, we identified 16 novel susceptibility loci for VTE; for some loci, the association signals are likely mediated through gene expression of nearby genes.

Abstract
Venous thromboembolism is a significant cause of mortality1, yet its genetic determinants are incompletely defined. We performed a discovery genome-wide association study in the Million Veteran Program and UK Biobank, with testing of approximately 13 million DNA sequence variants for association with venous thromboembolism (26,066 cases and 624,053 controls) and meta-analyzed both studies, followed by independent replication with up to 17,672 venous thromboembolism cases and 167,295 controls. We identified 22 previously unknown loci, bringing the total number of venous thromboembolism-associated loci to 33, and subsequently fine-mapped these associations. We developed a genome-wide polygenic risk score for venous thromboembolism that identifies 5% of the population at an equivalent incident venous thromboembolism risk to carriers of the established factor V Leiden p.R506Q and prothrombin G20210A mutations. Our data provide mechanistic insights into the genetic epidemiology of venous thromboembolism and suggest a greater overlap among venous and arterial cardiovascular disease than previously thought.

Abstract
Pulmonary embolism (PE) represents the third leading cause of cardiovascular mortality. The technological landscape for management of acute intermediate- and high-risk PE is rapidly evolving. Two interventional devices using pharmacomechanical means to recanalize the pulmonary arteries have recently been cleared by the US Food and Drug Administration for marketing, and several others are in various stages of development. The purpose of this document is to clarify the current state of endovascular interventional therapy for acute PE and to provide considerations for evidence development for new devices that will define which patients with PE would derive the greatest net benefit from their use in various clinical settings. First, definitions and limitations of commonly used risk stratification tools for PE are reviewed. An adjudication of risks and benefits of available interventional therapies for PE follows. Next, considerations for optimal future evidence development in this field are presented in the context of the current US regulatory framework. Finally, the document concludes with a discussion of the pros and cons of the rapidly expanding PE response team model of care delivery.

Abstract
Pulmonary embolism (PE) is a major cause of morbidity and mortality in the United States. Although new therapeutic tools and strategies have recently been developed for the diagnosis and treatment of patients with PE, the outcomes for patients who present with massive or high-risk PE remain dismal. To address this crisis, pulmonary embolism response teams (PERTs) are being created around the world in an effort to immediately and simultaneously engage multiple specialists to determine the best course of action and coordinate the clinical care for patients with acute PE. The scope of this review is to describe the PERT model and purpose, present the structure and organization, examine the available evidence for efficacy and usefulness, and propose future directions for research that is needed to demonstrate the value of PERT and determine if this multidisciplinary approach represents a new standard of care.

Abstract
OBJECTIVE The objective was to determine whether a protocol combining risk stratification, treatment with the direct-acting oral anticoagulant rivaroxaban, and defined follow-up is associated with a greater proportion of patients with venous thromboembolism (VTE) treated as outpatients, without hospital admission. METHODS We performed a multicenter study of patients diagnosed with VTE (pulmonary embolism [PE] or deep vein thrombosis [DVT]) in two urban EDs, 18 months before and 18 months after implementation of an outpatient VTE treatment protocol. Patients with radiographically confirmed acute VTE were eligible. Our primary outcome was the proportion of VTE patients discharged from the ED or observation unit (i.e., without hospital admission). We performed subgroup analyses according to hospital, DVT and PE, and low-risk PE. We also assessed 7- and 30-day mortality, major bleeding, and returns to the ED. We compared proportions using chi-square and Fisher's exact tests. RESULTS We enrolled 2,212 patients, 1,081 (49%) before protocol and 1,131 (51%) after protocol. Mean age (59 years vs. 60 years), female sex (49% vs. 49%), other demographics, comorbid illness, and PE risk stratification were similar before and after. After protocol, more VTE (35% from 26%, p < 0.001), PE (18% from 12%, p = 0.002), low-risk PE (28% from 18%, p < 0.001), and DVT (60% from 49%, p = 0.002) patients were treated as outpatients. Mortality, bleeding, and returns to ED were rare and did not increase after protocol. CONCLUSIONS A treatment protocol combining risk-stratification, rivaroxaban treatment and defined follow-up is associated with an increase in PE and DVT patients treated as outpatients, with no increase in adverse outcomes.

Abstract
Although recent Genome-Wide Association Studies have identified novel associations for common variants, there has been no comprehensive exome-wide search for low-frequency variants that affect the risk of venous thromboembolism (VTE). We conducted a meta-analysis of 11 studies comprising 8,332 cases and 16,087 controls of European ancestry and 382 cases and 1,476 controls of African American ancestry genotyped with the Illumina HumanExome BeadChip. We used the seqMeta package in R to conduct single variant and gene-based rare variant tests. In the single variant analysis, we limited our analysis to the 64,794 variants with at least 40 minor alleles across studies (minor allele frequency [MAF] ~0.08%). We confirmed associations with previously identified VTE loci, including ABO, F5, F11, and FGA. After adjusting for multiple testing, we observed no novel significant findings in single variant or gene-based analysis. Given our sample size, we had greater than 80% power to detect minimum odds ratios greater than 1.5 and 1.8 for a single variant with MAF of 0.01 and 0.005, respectively. Larger studies and sequence data may be needed to identify novel low-frequency and rare variants associated with VTE risk.

Abstract
Pulmonary Embolism Response Teams (PERTs) are being created around the United States to immediately and simultaneously bring together multiple specialists to determine the best course of action and coordinate clinical care for patients with severe pulmonary embolism (PE). The organization and structure of each PERT will depend on local clinical demands and resources. Creating a follow up clinic for PE patients after discharge from the hospital is an essential component of any PERT program. PERT programs, which have come together to form the PERT Consortium®, are changing the landscape of PE treatment and may represent a new standard of care.

Abstract
AIMS To provide a systematic review of catheter-based therapies of acute pulmonary embolism. METHODS AND RESULTS Studies published in peer-reviewed journals before February 2017 were included and categorized according to the mechanism of thrombus removal: fragmentation, rheolytic therapy, aspiration or catheter-directed thrombolysis. Strengths, challenges and the level of evidence of each device were evaluated. We found 16 different catheter-based therapies for acute PE; all but one being used off-label. The majority of procedures involve catheter-directed thrombolysis. Aspiration therapy shows promise, but limited data are available. Rheolytic therapy should be used with caution, if at all, due to the high number of associated complications. CONCLUSIONS Catheter-based therapies show promise as a treatment for acute PE, though evidence is lacking. Further research into the efficacy and safety of devices is needed.

Abstract
Importance It is uncertain to what extent established cardiovascular risk factors are associated with venous thromboembolism (VTE). Objective To estimate the associations of major cardiovascular risk factors with VTE, ie, deep vein thrombosis and pulmonary embolism. Design, Setting, and Participants This study included individual participant data mostly from essentially population-based cohort studies from the Emerging Risk Factors Collaboration (ERFC; 731 728 participants; 75 cohorts; years of baseline surveys, February 1960 to June 2008; latest date of follow-up, December 2015) and the UK Biobank (421 537 participants; years of baseline surveys, March 2006 to September 2010; latest date of follow-up, February 2016). Participants without cardiovascular disease at baseline were included. Data were analyzed from June 2017 to September 2018. Exposures A panel of several established cardiovascular risk factors. Main Outcomes and Measures Hazard ratios (HRs) per 1-SD higher usual risk factor levels (or presence/absence). Incident fatal outcomes in ERFC (VTE, 1041; coronary heart disease [CHD], 25 131) and incident fatal/nonfatal outcomes in UK Biobank (VTE, 2321; CHD, 3385). Hazard ratios were adjusted for age, sex, smoking status, diabetes, and body mass index (BMI). Results Of the 731 728 participants from the ERFC, 403 396 (55.1%) were female, and the mean (SD) age at the time of the survey was 51.9 (9.0) years; of the 421 537 participants from the UK Biobank, 233 699 (55.4%) were female, and the mean (SD) age at the time of the survey was 56.4 (8.1) years. Risk factors for VTE included older age (ERFC: HR per decade, 2.67; 95% CI, 2.45-2.91; UK Biobank: HR, 1.81; 95% CI, 1.71-1.92), current smoking (ERFC: HR, 1.38; 95% CI, 1.20-1.58; UK Biobank: HR, 1.23; 95% CI, 1.08-1.40), and BMI (ERFC: HR per 1-SD higher BMI, 1.43; 95% CI, 1.35-1.50; UK Biobank: HR, 1.37; 95% CI, 1.32-1.41). For these factors, there were similar HRs for pulmonary embolism and deep vein thrombosis in UK Biobank (except adiposity was more strongly associated with pulmonary embolism) and similar HRs for unprovoked vs provoked VTE. Apart from adiposity, these risk factors were less strongly associated with VTE than CHD. There were inconsistent associations of VTEs with diabetes and blood pressure across ERFC and UK Biobank, and there was limited ability to study lipid and inflammation markers. Conclusions and Relevance Older age, smoking, and adiposity were consistently associated with higher VTE risk.

Abstract
PURPOSE Evaluate the association between chronic right ventricle (RV) dysfunction by transthoracic echocardiogram (TTE) and outcomes in patients with acute pulmonary embolism (PE). METHODS This was a retrospective analysis of TTE findings in acute PEs. TTEs were used to classify the presence of chronic right ventricular pressure overload (RPVO), defined as RV hypertrophy or RV systolic pressure (RVSP) >50 mmHg, acute RVPO, defined as RV dysfunction not meeting the chronic RVPO definition, or no RV dysfunction. The primary outcome was a composite of death or need for advanced PE therapies at 7 days. RESULTS Of 466 patients, 288 had evidence of RV dysfunction. Thirty percent (140) had evidence of chronic RVPO and 148 patients had evidence of acute RVPO. Chronic RVPO patients were older (P = .004), more likely to have COPD, and had lower heart rates and troponin-t values. The acute RVPO patients included more women and were less likely to have a prior PE. There was no difference in outcomes between the acute and chronic RVPO cohorts. CONCLUSIONS Chronic RVPO patients had lower heart rates and troponin-t values. Despite these differences there were no differences in need for advanced therapeutic interventions or 7 day mortality.

Abstract
Background We provide the first multicenter analysis of patients cared for by eight Pulmonary Embolism Response Teams (PERTs) in the United States (US); describing the frequency of team activation, patient characteristics, pulmonary embolism (PE) severity, treatments delivered, and outcomes. Methods We enrolled patients from the National PERT Consortium™ multicenter registry with a PERT activation between 18 October 2016 and 17 October 2017. Data are presented combined and by PERT institution. Differences between institutions were analyzed using chi-squared test or Fisher's exact test for categorical variables, and ANOVA or Kruskal-Wallis test for continuous variables, with a two-sided P value < 0.05 considered statistically significant. Results There were 475 unique PERT activations across the Consortium, with acute PE confirmed in 416 (88%). The number of activations at each institution ranged from 3 to 13 activations/month/1000 beds with the majority originating from the emergency department (281/475; 59.3%). The largest percentage of patients were at intermediate–low (141/416, 34%) and intermediate–high (146/416, 35%) risk of early mortality, while fewer were at high-risk (51/416, 12%) and low-risk (78/416, 19%). The distribution of risk groups varied significantly between institutions (P = 0.002). Anticoagulation alone was the most common therapy, delivered to 289/416 (70%) patients with confirmed PE. The proportion of patients receiving any advanced therapy varied between institutions (P = 0.0003), ranging from 16% to 46%. The 30-day mortality was 16% (53/338), ranging from 9% to 44%. Conclusions The frequency of team activation, PE severity, treatments delivered, and 30-day mortality varies between US PERTs. Further research should investigate the sources of this variability.

Abstract
Objectives
In patients with suspected venous thromboembolism (VTE), the D-dimer assay is commonly utilized as part of the workup. The assay is primarily used to determine whether to proceed with radiographic imaging. We compared D-dimer levels in patients suspected of having VTE. We hypothesized that higher D-dimer values predict a higher likelihood of subsequent VTE diagnosis.
Methods
We conducted a secondary analysis of a multinational, prospective observational study of low- to intermediate-risk adult patients presenting to the emergency department with suspicion of VTE. Demographic and clinical data were collected in a structured manner. Advanced imaging including ultrasound, computed tomography (CT) pulmonary angiography, and ventilation/perfusion scanning was obtained at the discretion of the treating physicians. Imaging was evaluated by board-certified radiologists in real time. D-dimer values' bins were evaluated using a logistic regression model.
Results
We evaluated 1,752 patients for suspected deep vein thrombosis (DVT), with 191 (10.4%) DVT positive. We evaluated 1,834 patients for suspected pulmonary embolism (PE), with 108 (5.9%) PE positive. Higher D-dimer values in both groups were associated with higher likelihood of subsequent VTE diagnosis, with D-dimer values > 3,999 ng/mL in both groups having the highest incidence of VTE. More than 50% of those patients were VTE positive.
Conclusions
Increasing D-dimer values predict increased likelihood of being found VTE positive in this patient population. Among those in the highest D-dimer category, > 3,999 ng/mL, over half of patients were VTE positive. Further research could determine additional nuance in D-dimer as a tool to work up suspected VTE.

Contemporary Management and Outcomes of Patients with Massive and Submassive Pulmonary Embolism. Am J Med 2018; 131:1506-1514.e0.

Abstract
BACKGROUND Few contemporary studies have assessed the management and outcomes of patients with massive and submassive pulmonary embolism. Given advances in therapy, we report contemporary practice patterns and event rates among these patients. METHODS We analyzed a prospective database of patients with massive and submassive pulmonary embolism. We report clinical characteristics, therapies, and outcomes stratified by pulmonary embolism type. Treatment escalation beyond systemic anticoagulation was defined as advanced therapy. Cox proportional hazards regression was used to identify predictors of 90-day mortality. RESULTS Among 338 patients, 46 (13.6%) presented with massive and 292 (86.4%) with submassive pulmonary embolism. The average age was 63 ± 15 years, 49.9% were female, 32.0% had malignancy, and 21.9% had recent surgery. Massive pulmonary embolism patients received advanced therapy in 71.7% (30.4% systemic thrombolysis, 17.4% catheter-directed thrombolysis, 15.2% surgical embolectomy) and had greater 90-day mortality rates compared with submassive pulmonary embolism patients (41.3% vs 12.3%, respectively; P < .01). Most massive pulmonary embolism deaths (78.9%) occurred in-hospital, whereas mortality risk persisted after discharge for submassive pulmonary embolism. After multivariable adjustment, massive pulmonary embolism was associated with a 5.23-fold greater hazard of mortality (95% confidence interval, 2.70-10.13; P < .01). Advanced therapies among all pulmonary embolism patients were associated with a 61% reduction in mortality (95% confidence interval, 0.20-0.76; P < .01). CONCLUSIONS Among contemporary massive and submassive pulmonary embolism patients, mortality remains substantial. Advanced therapies were frequently utilized and independently associated with lower mortality. Further investigation is needed to determine how to improve outcomes among these high-risk patients, including the optimal use of advanced therapies.

Abstract
Background Venous thromboembolism ( VTE ) is a complex thrombotic disorder that constitutes a major source of mortality and morbidity. To improve understanding of the cause of VTE , we conducted a metabolomic analysis in a case-control study including 240 incident VTE cases and 6963 controls nested within 3 large prospective population-based cohorts, the Nurses' Health Study, the Nurses' Health Study II , and the Health Professionals Follow-Up Study. Methods and Results For each individual, we measured 211 metabolites and collected detailed information on lifestyle factors. We performed logistic regression and enrichment analysis to identify metabolites and biological categories associated with incident VTE risk, accounting for key confounders, such as age, sex, smoking, alcohol consumption, body mass index, and comorbid diseases (eg, cancers). We performed analyses of all VTEs and separate analyses of pulmonary embolism. Using the basic model controlling for age, sex, and primary disease, we identified 60 nominally significant VTE - or pulmonary embolism-associated metabolites ( P<0.05). These metabolites were enriched for diacylglycerols ( Ppermutation<0.05). However, after controlling for multiple testing, only 1 metabolite (C5 carnitine; odds ratio, 1.25; 95% confidence interval, 1.10-1.41; Pcorrected=0.03) remained significantly associated with VTE . After further adjustment for body mass index, no metabolites were significantly associated with disease after accounting for multiple testing, and no metabolite classes were enriched for nominally significant associations. Conclusions Although our findings suggest that circulating metabolites may influence the risk of incident VTE , the associations we observed were confounded by body mass index. Larger studies involving additional individuals and with broader metabolomics coverage are needed to confirm our findings.

Abstract
OBJECTIVE Adult body mass index (BMI) is strongly associated with venous thromboembolism (VTE), however whether earlier-life adiposity or other measures of adult adiposity are associated with VTE risk remains largely unknown. MATERIALS AND METHODS We evaluated associations of childhood somatotype, BMI in early adulthood, adult adiposity, and change in weight since early adulthood with incident VTE risk over ≥20 years of follow-up among 205,935 participants from Nurses' Health Studies (NHS/NHS II) and Health Professionals Follow-Up Study (HPFS), ages 29-76 at baseline. We estimated multivariable-adjusted hazard ratios for VTE using Cox proportional hazards models. RESULTS AND CONCLUSIONS Somatotype in childhood and young adulthood BMI were not significantly associated with VTE risk, after accounting for adult BMI. Adult BMI was strongly associated with VTE in all three cohorts (e.g., multivariable-adjusted HRs comparing ≥35 kg/m2 vs. <22.5 kg/m2: NHS:3.03[95% CI: 2.58, 3.56], NHS II:3.82[95% CI: 3.24, 4.51], HPFS:2.81 [95% CI: 2.08, 3.80]; all p-trends < 0.01). Adult waist circumference was associated with greater VTE risk, even after adjusting for adult BMI (all p-trends < 0.01). Increasing weight gain from young adulthood was significantly associated with VTE after adjusting for current BMI among women (HR comparing gain ≥20 kg vs. no change: NHS:1.36[95% CI: 1.13, 1.65], NHS II:1.48[95% CI: 1.17, 1.87]) and not men (HPFS:1.20[95% CI: 0.97, 1.50]). These results indicate that BMI and adiposity are likely more important acutely than cumulatively over time in the etiology and prevention of VTE. Clinically, encouraging weight loss in individuals who are overweight or obese could help reduce VTE risk.

Abstract
Background Hospitalization for low‐risk pulmonary embolism (PE) is common, expensive, and of questionable benefit. Objective The objective was to determine if low‐risk PE patients discharged from the emergency department (ED) on rivaroxaban require fewer hospital days compared to standard of care (SOC). Methods Multicenter, open‐label randomized trial in low‐risk PE defined by Hestia criteria. Adult subjects were randomized to early ED discharge on rivaroxaban or SOC. Primary outcome was total number of initial hospital hours, plus hours of hospitalization for bleeding or venous thromboembolism (VTE), 30 days after randomization. A 90‐day composite safety endpoint was defined as major bleeding, clinically relevant nonmajor bleeding, and mortality. Results Of 114 randomized subjects, 51 were early discharge and 63 were SOC. Of 112 (98.2%) receiving at least one dose of study drug, 99 (86.8%) completed the study. Initial hospital LOS was 4.8 hours versus 33.6 hours, with a mean difference of –28.8 hours (95% confidence interval [CI] = –42.55 to –15.12 hours) for early discharge versus SOC, respectively. At 90 days, mean total hospital days (for any reason) were less for early discharge than SOC, 19.2 hours versus 43.2 hours, with a mean difference of 26.4 hours (95% CI = –46.97 to –3.34 hours). At 90 days, there were no bleeding events, recurrent VTE, or deaths. The composite safety endpoint was similar in both groups, with a difference in proportions of 0.005 (95% CI = –0.18 to 0.19). Total costs were $1,496 for early discharge and $4,234 for SOC, with a median difference of $2,496 (95% CI = –$2,999 to –$2,151). Conclusions Low‐risk ED PE patients receiving early discharge on rivaroxaban have similar outcomes to SOC, but fewer total hospital days and lower costs over 30 days.

Abstract
Essentials The association of moderate alcohol consumption with pulmonary embolism (PE) risk remains unclear. In three large US cohorts, we evaluated the association of alcohol consumption with PE risk. We found no evidence of an association of alcohol consumption amount or frequency with PE risk. Secondary analyses of type and heavy episodic drinking also yielded null findings. SUMMARY Background Moderate alcohol consumption has been variably associated with hemostatic and fibrinolytic factor levels, but the association between alcohol consumption and the risk of incident pulmonary embolism (PE) remains uncertain. Objective To evaluate alcohol consumption amount and frequency in relation to PE risk. Methods Nurses' Health Study (NHS), NHS II and Health Professionals Follow-Up Study participants free of venous thromboembolism (VTE) at baseline (n = 217 442) reported alcohol consumption by type, quantity and frequency, every 2-4 years. Incident PE cases were identified by self-report and confirmed for participants without cancer. In this cohort study, we used Cox proportional hazards models to estimate multivariable-adjusted hazard ratios (HRs) for PE associated with alcohol consumption amount and, separately, frequency. Secondary analyses evaluated alcohol type and heavy episodic drinking in relation to PE risk, and amount and frequency in relation to medical record-confirmed idiopathic PE and any self-reported VTE risk. Cohort-specific analyses were pooled using random-effects meta-analysis. Results During ≥ 20 years of follow-up, we identified 1939 PE events. We found no strong evidence of an association between PE risk and alcohol consumption amount (pooled HRadj for 5.0-14.9 g day-1 vs. abstention = 0.97 [95% CI, 0.79, 1.20]) or frequency (pooled HRadj for 5-7 drinking days per week vs. abstention = 1.04 [95% CI, 0.88, 1.23]). Secondary analyses of type, heavy episodic drinking, idiopathic PE and VTE also yielded null findings. Conclusions Among three large prospective cohorts of US men and women, we found no evidence of an association between the amount or frequency of alcohol consumption and PE risk.

Abstract
BACKGROUND It may be possible to safely rule out pulmonary embolism (PE) in patients with low pretest probability (PTP) using a higher than standard D-dimer threshold. The YEARS criteria, which include three questions from the Wells PE score to identify low-PTP patients and a variable D-dimer threshold, was recently shown to decrease the need for imaging to rule out PE by 14% in a multicenter study in the Netherlands. However, the YEARS approach has not been studied in the United States. METHODS This study was a prospective, observational study of consecutive adult patients evaluated for PE in 17 U.S. emergency departments. Prior to diagnostic testing, we collected the YEARS criteria: "Does the patient have clinical signs or symptoms of DVT?" "Does the patient have hemoptysis?" "Are alternative diagnoses less likely than PE?" with YEARS (+) being any "yes" response. A negative D-dimer was <1000 mg/dL for YEARS (-) patients and <500 mg/dL for YEARS (+) patients. We calculated test characteristics and used Fisher's exact test to compare proportions of patients who would have been referred for imaging and patients who would have had PE "missed." RESULTS Of 1,789 patients, 84 (4%) had PE, 1,134 (63%) were female, 1,038 (58%) were white, and mean (±SD) age was 48 (±16) years. Using the standard D-dimer threshold, 940 (53%) would not have had imaging, with two (0.2%, 95% confidence interval [CI] = 0.02%-0.60%) missed PE. Using YEARS adjustment, 1,204 (67%, 95% CI = 65%-69%) would not have been referred for imaging, with six (0.5%, 95% CI = 0.18%-1.1%) missed PE, and using "alternative diagnoses less likely than PE" adjustment, 1,237 (69%, 95% CI = 67%-71%) would not have had imaging with six (0.49%, 95% CI = 0.18%-1.05%) missed PE. Sensitivity was 97.6% (95% CI = 91.7%-99.7%) for the standard threshold and 92.9% (95% CI = 85%-97%) for both adjusted thresholds. Negative predictive value (NPV) was nearly 100% for all approaches. CONCLUSIONS D-dimer adjustment based on PTP may result in a reduced need for imaging to evaluate possible PE, with some additional missed PE but no decrease in NPV.

Abstract
Background: Extracorporeal membrane oxygenation (ECMO) has been used to stabilize patients with massive pulmonary embolism though few reports describe this approach. We describe the presentation, management and outcomes of patients who received ECMO for massive pulmonary embolism (PE) in our pulmonary embolism response team (PERT) registry. Methods: We enrolled a consecutive cohort of patients with confirmed PE for whom PERT was activated and selected patients treated with ECMO. We prospectively captured clinical, therapeutic and outcome data at the time of PERT activation and during the follow-up period for up to 365 days. Results: Thirteen patients who had PERT activation with confirmed PE diagnosis have undergone ECMO since the initiation of our PERT program in 2012. The mean age was 49 ± 19 years. Six (46%) patients were female. All the patients had cardiac arrest, either as an initial presentation or in-hospital cardiac arrest after presentation. All the patients exhibited right ventricular (RV) dilation on echocardiogram with RV hypokinesis. Eight (62%) patients received systemic thrombolysis with intravenous tissue plasminogen activator (tPA) and three (23%) patients underwent catheter-directed thrombolysis therapy using the EKOS system (EKOS Corporation, Bothell, WA, USA). Four (31%) patients underwent surgical embolectomy. Mean ECMO duration was 5.5 days, ranging from 2-18 days. Thirty-day mortality was 31% and one-year mortality was 54%. Conclusions: Patients with massive pulmonary embolism who suffer a cardiac arrest have high morbidity and mortality. ECMO can be used in conjunction with systemic thrombolysis, catheter-directed therapy or as a bridge to surgical embolectomy.

Abstract
Essentials The association of venous thromboembolism (VTE) with subsequent physical function remains unclear. We prospectively evaluated this relationship among women from the Nurses' Health Studies. We found a decline in physical function over four years in women with incident VTE. This decline was somewhat greater among women specifically reporting a pulmonary embolism. SUMMARY Background Physical function is integral to healthy aging; however, limited research has examined the association of venous thromboembolism(VTE) with subsequent physical function. Objectives To prospectively evaluate the relationship between VTE and decline in physical function among 80 836 women from the Nurses' Health Study(NHS), ages 46-72 in 1992, and 84 304 women from the Nurses' Health Study II(NHS II), ages 29-48 in 1993. Methods Physical function was measured by the Medical Outcomes Short Form-36 physical function scale, administered every 4 years. We compared change in physical function for women with vs. without an incident VTE in each 4-year follow-up period using multivariable linear regression. Results We observed a decline in physical function over 4 years when comparing women with vs. those without incident VTE in both older (NHS) and younger (NHS II) women (multivariable-adjusted mean difference NHS, -6.5 points [95% CI -7.4, -5.6] per 4 years; NHS II, -3.8 [95% CI -5.6, -2.0]). This difference appeared greater among women specifically reporting a pulmonary embolism (NHS, -7.4 [95% CI -8.7, -6.1]; NHS II, -4.8 [95% CI -6.8, -2.8]), and was equivalent to 6.2 years of aging. Whereas longer-term slopes of physical function decline following a VTE were not different from the slopes of decline in women without a VTE, the absolute level of physical function of women with VTE was worse at the end of follow-up compared to women without VTE. Conclusions In this prospective cohort, incident VTE was strongly associated with an acute decline in physical function. These results suggest it may be clinically important to consider approaches to ameliorating functional deficits shortly after VTE diagnosis.
