RESUMO
Background: Despite advances in therapy options, pulmonary embolism (PE) continues to carry a high risk of mortality and morbidity. Currently, therapeutic options are limited with only 2 US Food and Drug Administration-cleared catheter-based embolectomy devices approved for the treatment of intermediate-risk PE. The novel Helo PE thrombectomy catheter (Endovascular Engineering, Inc) has a flexible and collapsible funnel with an internal agitator for a dual mechanism of treatment for acute PE. We sought to investigate the safety and feasibility of the novel Helo PE thrombectomy catheter in intermediate-risk PE. Methods: A prospective, single-arm feasibility study evaluating the Helo PE catheter was performed in patients presenting with intermediate-risk PE. Patients underwent preprocedural and postprocedural computed tomography angiography. Primary efficacy was the difference in preprocedural to postprocedural right ventricle/left ventricle (RV/LV) ratio. Primary and secondary safety outcomes were all-cause mortality, major life-threatening bleeding, device-related serious adverse events, pulmonary or cardiac injury, and clinical decompensation at 48 hours postprocedure and at 30 days. Results: A total of 25 patients from 8 centers were consented and included in the analysis. Preprocedural computed tomography angiography revealed an RV/LV ratio of 1.53 ± 0.27. All patients underwent a successful thrombectomy procedure. Postprocedure, the RV/LV ratio was reduced to 1.15 ± 0.18, translating into a 23.2 ± 12.81% decrease from baseline. No patients underwent adjunctive thrombolysis. Two patients had adjunctive catheter-directed embolectomy with an alternative device. Two patients had postprocedural anemia requiring transfusion but did not meet criteria for major life-threatening bleeding by VARC-2 criteria. There were no major adverse events including no deaths, major bleeding, pulmonary injury, or vascular complications at 48 hours or 30 days post procedure. Conclusions: In this multicenter first-in-human study, use of the Helo PE thrombectomy catheter was feasible and safe for the treatment of acute PE.
RESUMO
Venous thromboembolism, commonly presented as pulmonary embolism and deep-vein thrombosis, is a paramount and potentially fatal condition with variable clinical presentation. Diagnosis is key to providing appropriate treatment in a safe and timely fashion. Clinical judgment and assessment using clinical scoring systems should guide diagnostic testing, including laboratory and imaging modalities, for optimal results and to avoid unnecessary testing.
RESUMO
BACKGROUND: Only a few small studies have shown the association between high ankle-brachial pressure index (ABI >1.4) and adverse cardiovascular (CV) events and mortality. Although there is abundant literature depicting the association between ABI and overall systemic atherosclerosis, it typically focuses on low ABI. Furthermore, historically, many studies focusing on peripheral artery disease have excluded high ABI participants. We aimed to study the mortality outcomes of persons with high ABI in the National Health and Nutrition Examination Survey (NHANES). METHODS: We obtained ABI from participants aged ≥40 years for survey years 1999 to 2004. We defined low a ABI as ≤0.9, normal ABI as 0.9 to 1.4, and high ABI as >1.4 or if the ankle pressures were >245 mm Hg. Demographics, various comorbidities, and laboratory test results were obtained at the time of the survey interview. Multivariable adjusted hazard ratios (HRs) along with 95% confidence intervals (CIs) were calculated for CV and all-cause mortality via Cox proportional hazards regression. Mortality was linked to all NHANES participants for follow-up through December 31, 2019, by the Centers for Disease Control and Prevention. RESULTS: We identified 7639 NHANES participants with available ABI. Of these, 6787 (89%) had a normal ABI, 646 (8%) had a low ABI, and 206 (3%) had elevated ABI. Of participants with high ABI, 50% were men, 15% were African Americans, 10% were current smokers, 56% had hypertension, 33% had diabetes, 15% had chronic kidney disease (CKD), and 18% had concomitant coronary artery disease (CAD). Diabetes (odds ratio [OR], 2.4; 95% CI, 1.7-3.2), CAD (OR, 1.6; 95% CI, 1.0-2.4), and CKD (OR, 1.5; 95% CI, 1.0-2.3) at baseline were associated with having a high ABI, respectively. A high ABI was associated independently with elevated CV (HR, 2.6; 95% CI, 2.1-3.1; P < .0001) and all-cause mortality (HR, 2.5; 95% CI, 2.2-2.8; P < .0001) after adjusting for covariates, including diabetes, CKD, CAD, current smoking, cancer, and hypertension. CONCLUSIONS: A high ABI is associated with an elevated CV and all-cause mortality, similar to patients with PAD. High ABI participants should receive the same attention and aggressive medical therapies as patients with PAD.
RESUMO
PURPOSE: To report the first interim analysis of the STRIKE-PE study, evaluating the safety and effectiveness of computer assisted vaccum thrombectomy (CAVT) for the treatment of acute pulmonary embolism (PE). MATERIALS AND METHODS: This prospective, international, multicenter study will enroll 600 adult patients with acute PE of ≤14 days and a right ventricle (RV)-to-left ventricle (LV) ratio of ≥0.9 who receive first-line endovascular treatment with CAVT using the Indigo Aspiration System (Penumbra, Alameda, California). Primary endpoints are change in RV/LV ratio and incidence of composite major adverse events (MAEs) within 48 hours. Secondary endpoints include functional and quality-of-life (QoL) assessments. RESULTS: The first 150 consecutive patients were treated with 12F catheter CAVT. Mean age was 61.3 years, 54.7% were men, 94.7% presented with intermediate-risk PE, and 5.3% presented with high-risk PE. Median thrombectomy and procedure times were 33.5 minutes and 70.0 minutes, respectively, resulting in a mean reduction in systolic pulmonary artery pressure of 16.3% (P < .001). Mean RV/LV ratio decreased from 1.39 to 1.01 at 48 hours, a 25.7% reduction (P < .001). Four (2.7%) patients experienced a composite MAE within 48 hours. At 90-day follow-up, patients exhibited statistically significant improvements in the Borg dyspnea scale score and QoL measures, and the New York Heart Association class distribution returned to that reported before the index PE. CONCLUSIONS: Interim results from the STRIKE-PE study demonstrate a significant reduction in pulmonary artery pressure and RV/LV ratio, a median thrombectomy time of 33.5 minutes, a composite MAE rate of 2.7%, and significant improvements in 90-day functional and QoL outcomes.

BACKGROUND: The role of advanced therapies (systemic thrombolysis, catheter-based treatment, and surgical thrombectomy) for the management of right heart thrombus is poorly defined. In this study, we assessed the clinical predictors and outcomes of advanced therapy compared with anticoagulation alone for the acute management of right heart thrombus. METHODS: In this observational cohort study, we analyzed consecutive patients who were treated for right heart thrombus. The primary end point was 90-day all-cause mortality. Clinical predictors of utilizing advanced therapy were assessed with multivariable logistic regression. Propensity score matching was utilized to compare adjusted outcomes between patients receiving advanced therapies versus anticoagulation alone. RESULTS: A total of 345 patients were included in the study. Advanced therapy was utilized in 13.6% (N=47) of patients, of which 25.5% (N=12/47) was systemic thrombolysis, 23.4% (N=11/47) was endovascular thrombectomy, and 53.2% (N=25/47) was surgical thrombectomy. Younger age (odds ratio, 0.98 [95% CI, 0.96-0.99]) and concurrent pulmonary embolism (odds ratio, 5.36 [95% CI, 2.48-12.1]) predicted utilization of advanced therapy. In propensity score-matched analysis, there was no difference in 90-day mortality (hazard ratio, 0.46 [95% CI, 0.17-1.22]), in-hospital mortality (odds ratio, 0.64 [95% CI, 0.17-2.19]), or length of stay (ß, -4.39 [95% CI, -14.0 to 5.22]) between advanced therapy and anticoagulation. CONCLUSIONS: Among a diverse cohort of patients with right heart thrombus, outcomes did not differ between those who underwent advanced therapy and anticoagulation alone. Important predictors for utilizing advanced treatment included younger age and the presence of a concurrent pulmonary embolism. Future studies assessing advanced therapy in larger and broader patient populations are necessary.

INTRODUCTION: Although older adults represent a significant proportion of patients with venous thromboembolism (VTE), the data on the impact of age-related differences in the clinical presentation, management, and outcomes of VTE are scarce. METHODS: We analyzed data from the RIETE registry database, an ongoing global observational registry of patients with objectively confirmed VTE, to compare patient characteristics, clinical presentation, treatments, and outcomes between elderly (≥70 years) vs. non-elderly (<70 years) patients. RESULTS: From January 2001 to March 2021, 100,000 adult patients were enrolled in RIETE. Elderly patients (47.9%) were more frequently women (58.2% vs. 43.5%), more likely had unprovoked VTE (50.5% vs. 45.1%) and most often presented with severe renal failure (10.2% vs. 1.2%) and acute pulmonary embolism (PE) (vs. deep vein thrombosis) (54.3% vs. 44.5%) compared to non-elderly patients (p<0.001 for all comparisons). For the PE subgroup, elderly patients more frequently had non-low risk PE (78.9% vs. 50.7%; p<0.001), respiratory failure (33.9% vs. 21.8%; p<0.001) and myocardial injury (40.0% vs. 26.2%; p<0.001) compared to non-elderly patients. Thrombolysis (0.9% vs. 1.7%; p<0.001) and direct oral anticoagulants (8.8% vs. 11.8%; p<0.001) were less frequently administered to elderly patients. Elderly patients showed a significantly higher 30-day all-cause mortality (adjusted odds ratio [OR] 1.36, 95%CI: 1.22-1.52) and major bleeding (OR, 2.08; 95%CI, 1.85-2.33), but a lower risk of 30-day VTE recurrences (OR, 0.62, 95%CI, 0.54-0.71). CONCLUSIONS: Compared with non-elderly patients, elderly patients had a different VTE clinical profile. Advanced therapies were less frequently used in older patients. Age was an independent predictor of mortality.

BACKGROUND: Among patients with chronic limb-threatening ischemia (CLTI) and infrapopliteal artery disease, angioplasty has been associated with frequent reintervention and adverse limb outcomes from restenosis. The effect of the use of drug-eluting resorbable scaffolds on these outcomes remains unknown. METHODS: In this multicenter, randomized, controlled trial, 261 patients with CLTI and infrapopliteal artery disease were randomly assigned in a 2:1 ratio to receive treatment with an everolimus-eluting resorbable scaffold or angioplasty. The primary efficacy end point was freedom from the following events at 1 year: amputation above the ankle of the target limb, occlusion of the target vessel, clinically driven revascularization of the target lesion, and binary restenosis of the target lesion. The primary safety end point was freedom from major adverse limb events at 6 months and from perioperative death. RESULTS: The primary efficacy end point was observed (i.e., no events occurred) in 135 of 173 patients in the scaffold group and 48 of 88 patients in the angioplasty group (Kaplan-Meier estimate, 74% vs. 44%; absolute difference, 30 percentage points; 95% confidence interval [CI], 15 to 46; one-sided P<0.001 for superiority). The primary safety end point was observed in 165 of 170 patients in the scaffold group and 90 of 90 patients in the angioplasty group (absolute difference, -3 percentage points; 95% CI, -6 to 0; one-sided P<0.001 for noninferiority). Serious adverse events related to the index procedure occurred in 2% of the patients in the scaffold group and 3% of those in the angioplasty group. CONCLUSIONS: Among patients with CLTI due to infrapopliteal artery disease, the use of an everolimus-eluting resorbable scaffold was superior to angioplasty with respect to the primary efficacy end point.

Background: Patients with brain cancer have been excluded or were underrepresented in studies on the treatment of venous thromboembolism (VTE), mainly due to the fear of intracranial hemorrhage (ICH). Objectives: The aim of this study was to provide data on the risk of ICH, recurrent VTE, and major bleeding in patients with active brain cancer. Methods: This was a multicenter, international cohort study at participating sites of the Registro Informatizado Enfermedad Tromboembólica Registry. Patients included in this study were classified as having known active brain cancer, active nonbrain cancer, or without active cancer. ICH at 3 months was the primary study outcome. Results: Overall, 98,377 patients with VTE were included: 616 with active brain cancer, 16,807 with active nonbrain cancer, and 80,954 without active cancer. At 3 months follow-up, ICH occurred in 2.8%, 0.3%, and 0.2% of the patients, respectively, and was fatal in 1.3%, 0.2%, and 0.1%, respectively. Both rates of major bleeding (3.7% vs 3.2% vs 1.5%, respectively) and recurrent VTE (3.9% vs 3.4% vs 1.1%, respectively) were higher in patients with brain or nonbrain cancer than in patients without cancer. Glioblastomas were associated with a numerically higher risk of ICH, fatal ICH, and recurrent VTE than other brain tumors. Conclusion: In patients with VTE, active brain cancer was associated with a higher risk of ICH or fatal ICH than nonbrain or no active cancer. Further studies are needed to assess the value of different treatment approaches in patients with brain cancer and VTE.
RESUMO
BACKGROUND: Effective and durable options for infrapopliteal artery revascularization for patients with chronic limb-threatening ischemia (CLTI) are limited. METHODS: The SAVAL trial is a prospective, multicenter, randomized trial of patients with CLTI and infrapopliteal artery lesions with total lesion length ⩽ 140 mm, stenosis ⩾ 70%, and Rutherford category 4-5 assigned 2:1 to treatment with the SAVAL self-expandable paclitaxel drug-eluting stent (DES) or percutaneous transluminal angioplasty (PTA) with an uncoated balloon. The primary effectiveness endpoint was primary vessel patency (i.e., core lab-adjudicated duplex ultrasound-based flow at 12 months in the absence of clinically driven target lesion revascularization or surgical bypass of the target lesion). The primary safety endpoint was the 12-month major adverse event (MAE)-free rate; MAEs were defined as a composite of above-ankle index limb amputation, major reintervention, and 30-day mortality. The endpoints were prespecified for superiority (effectiveness) and noninferiority (safety) at a one-sided significance level of 2.5%. RESULTS: A total of 201 patients were enrolled and randomly assigned to treatment (N = 130 DES, N = 71 PTA). Target lesion length was 68.1 ± 35.2 mm for the DES group and 68.7 ± 49.2 mm for the PTA group, and 31.0% and 27.6% of patients, respectively, had occlusions. The 12-month primary patency rates were 68.0% for the DES group and 76.0% for the PTA group (Psuperiority = 0.8552). The MAE-free rates were 91.6% and 95.3%, respectively (Pnoninferiority = 0.0433). CONCLUSION: The SAVAL trial did not show benefit related to effectiveness and safety with the nitinol DES compared with PTA in infrapopliteal artery lesions up to 140 mm in length. Continued innovation to provide optimal treatments for CLTI is needed. (ClinicalTrials.gov Identifier: NCT03551496).

BACKGROUND: Right heart thrombus is a rare but serious form of venous thromboembolic disease that may be associated with pulmonary embolism. The prognosis of patients with right heart thrombus presenting without a concomitant pulmonary embolism remains ill-defined. METHODS: We conducted a multi-center observational cohort study to compare patients presenting with right heart thrombus with and without a concurrent pulmonary embolism. The primary endpoint was 90-day all-cause mortality. Multivariable regression was utilized to assess primary and secondary outcomes. RESULTS: Of 231 patients with right heart thrombus, 104 (45.0%) had a pulmonary embolism at admission. The median age of the cohort was 59.4 years (interquartile range 44.9-71.3). Pulmonary embolism in the setting of a right heart thrombus was associated with an increased adjusted hazard of 90-day mortality (hazard ratio 3.68; 95% confidence interval [CI], 1.51-8.97). Additionally, these patients had a higher adjusted risk of in-hospital mortality (odds ratio [OR] 2.55; 95% CI, 1.15-5.94) and admission to the intensive care unit (OR 2.45; 95% CI, 1.23-4.94). Thrombus mobility (OR 2.99; 95% CI, 1.35-6.78) and larger thrombus sizes (OR 1.04; 95% CI, 1.00-1.07) were associated with development of concurrent pulmonary embolism. CONCLUSIONS: Patients with right heart thrombus and pulmonary embolism had a more severe clinical presentation, required more advanced therapies, and had reduced survival compared with those without a concomitant pulmonary embolism. Important variables associated with development of concomitant pulmonary embolism include thrombus mobility and size. Right heart thrombus in the setting of acute pulmonary embolism represents a unique clinical entity that is associated with worse prognosis compared with right heart thrombus only.
RESUMO
BACKGROUND: Hypoechoic peri-stent areas in duplex ultrasonography (DUS) (ie, "halo") have been noted following femoropopliteal artery stenting. OBJECTIVES: This study sought to investigate the prevalence, risk factors, and potential safety implications of hypoechoic halos identified with DUS following stent implantation in the IMPERIAL (ELUVIA Drug-Eluting Stent Versus Zilver PTX Stent) and EMINENT (Trial Comparing ELUVIA Versus Bare Metal Stent in Treatment of Superficial Femoral and/or Proximal Popliteal Artery) trials. METHODS: The IMPERIAL and EMINENT studies of femoropopliteal artery stenting included polymer-based drug-eluting stent, nonpolymer drug-coated stent, and bare metal stent treatment arms. A dedicated DUS protocol was implemented for core laboratory assessment of halo presence at study follow-up visits. Logistic regressions were used to investigate risk factors for a halo sign and its impact on clinically driven target lesion revascularization and primary patency. RESULTS: Diagnostic DUS imaging from 659 patients was obtained at time points ranging from 6 months to 5 years post-stent implantation. Halo prevalence ranged from 20% to 35% of patients with diagnostic DUS and was present at all time intervals. Halos were identified surrounding all stent types. In analyses of patients with diagnostic imaging from at least 2 visits, halo presence typically persisted, with occasional cases of regression and development at later times. No statistically significant association was found for halo status (ie, halo vs no halo) on 1-year clinically driven target lesion revascularization (OR: 1.27; 95% CI: 0.70-2.30; P = 0.4240) or primary patency (OR: 0.68; 95% CI: 0.43-1.07; P = 0.0927). CONCLUSIONS: A hypoechoic halo following a femoropopliteal stent procedure is a common occurrence associated with all studied stent types. The presence of a halo appears to be benign with no associated clinical sequelae or effect on target vessel revascularization rates within 1 year of stent implantation.

PURPOSE: To state the position of the Society of Interventional Radiology (SIR) on the endovascular management of chronic iliofemoral venous obstruction with metallic stents. MATERIALS AND METHODS: A multidisciplinary writing group with expertise in treating venous disease was convened by SIR. A comprehensive literature search was conducted to identify studies on the topic of interest. Recommendations were drafted and graded according to the updated SIR evidence grading system. A modified Delphi technique was used to achieve consensus agreement on the recommendation statements. RESULTS: A total of 41 studies, including randomized trials, systematic reviews and meta-analyses, prospective single-arm studies, and retrospective studies were identified. The expert writing group developed 15 recommendations on the use of endovascular stent placement. CONCLUSIONS: SIR considers the use of endovascular stent placement for chronic iliofemoral venous obstruction to be likely to help selected patients, but the risks and benefits have not been fully quantified in well-designed randomized studies. SIR recommends urgent completion of such studies. In the meantime, careful patient selection and optimization of conservative therapy are recommended prior to stent placement, with attention to appropriate stent sizing and quality procedural technique. The use of multiplanar venography with intravascular ultrasound is suggested in diagnosing and characterizing obstructive iliac vein lesions and in guiding stent therapy. After stent placement, SIR recommends close patient follow-up to ensure optimal antithrombotic therapy, durable symptom response, and early identification of adverse events.

OBJECTIVES: The use of optimal medical therapy (OMT) in patients with chronic limb-threatening ischemia (CLTI) has not been well-studied. The Best Endovascular vs Best Surgical Therapy in Patients with CLTI study (BEST-CLI) is a multicenter, randomized, controlled trial sponsored by the National Institutes of Health comparing revascularization strategies in patients with CLTI. We evaluated the use of guideline-based OMT among patients with CLTI at the time of their enrollment into the trial. METHODS: A multidisciplinary committee defined OMT criteria related to blood pressure and diabetic management, lipid-lowering and antiplatelet medication use, and smoking status for patients enrolled in BEST-CLI. Status reports indicating adherence to OMT were provided to participating sites at regular intervals. Baseline demographic characteristics, comorbid medical conditions, and use of OMT at trial entry were evaluated for all randomized patients. A linear regression model was used to identify the relationship of predictors to the use of OMT. RESULTS: At the time of randomization (n = 1830 total enrolled), 87% of patients in BEST-CLI had hypertension, 69% had diabetes, 73% had hyperlipidemia, and 35% were currently smoking. Adherence to four OMT components (controlled blood pressure, not currently smoking, use of one lipid-lowering medication, and use of an antiplatelet agent) was modest. Only 25% of patients met all four OMT criteria; 38% met three, 24% met two, 11% met only one, and 2% met none. Age ≥80 years, coronary artery disease, diabetes, and Hispanic ethnicity were positively associated, whereas Black race was negatively associated, with the use of OMT. CONCLUSIONS: A significant proportion of patients in BEST-CLI did not meet OMT guideline-based recommendations at time of entry. These data suggest a persistent major gap in the medical management of patients with advanced peripheral atherosclerosis and CLTI. Changes in OMT adherence over the course of the trial and their impact on clinical outcomes and quality of life will be assessed in future analyses.

INTRODUCTION: Racial disparities exist in patients with peripheral artery disease (PAD), with Black individuals having worse PAD-specific outcomes. However, mortality risk in this population has been mixed. As such, we sought to evaluate all-cause mortality by race among individuals with PAD. METHODS: We analyzed data from the National Health and Nutrition Examination Survey (NHANES). Baseline data were obtained from 1999 to 2004. Patients with PAD were grouped according to self-reported race. Multivariable Cox proportional hazards regression was performed to calculate adjusted hazard ratios (HR) by race. A separate analysis was performed to study the effect of burden of social determinants of health (SDoH) on all-cause mortality. RESULTS: Of 647 individuals identified, 130 were Black and 323 were White. Black individuals had more premature PAD (30% vs 20%, p < 0.001) and a higher burden of SDoH compared to White individuals. Crude mortality rates were higher in Black individuals in the 40-49-year and 50-69-year age groups compared to White individuals (6.7% vs 6.1% and 8.8% vs 7.8%, respectively). Multivariable analysis demonstrated that Black individuals with both PAD and coronary artery disease (CAD) had a 30% higher hazard of death over 20 years compared to White individuals (HR = 1.3, 95% CI: 1.0-2.1). The cumulative burden of SDoH marginally (10-20%) increased the risk of all-cause mortality. CONCLUSIONS: In a nationally representative sample, Black individuals with PAD and CAD had higher rates of mortality compared to their White counterparts. These findings add further proof to the ongoing racial disparities among Black individuals with PAD and highlight the necessity to identify ways to mitigate these differences.

AIMS: To examine the shot-term outcomes with catheter-directed thrombolysis (CDT) vs. catheter-directed embolectomy (CDE) for high-risk pulmonary embolism (PE). METHODS AND RESULTS: The Nationwide Readmissions Database was utilized to identify hospitalizations with high-risk PE undergoing CDE or CDT from 2016 to 2019. The main outcome was all-cause in-hospital mortality. Propensity score matching was used to compare the outcomes in both groups. Among 3216 high-risk PE hospitalizations undergoing catheter-directed interventions, 868 (27%) received CDE, 1864 (58%) received CDT, and 484 (15%) received both procedures. In the unadjusted analysis, the rate of all-cause in-hospital mortality was not different between CDE and CDT (39.6% vs. 34.2%, P = 0.07). After propensity score matching, there was no difference in the incidence of in-hospital mortality [adjusted odds ratio (aOR): 1.28, 95% confidence interval (CI): 0.95, 1.72, P = 0.10], intracranial haemorrhage (ICH) (adjusted OR 1.57, 95% CI: 0.75, 3.29, P = 0.23), or non-ICH bleeding (aOR: 1.17, 95% CI: 0.85, 1.62, P = 0.33). There were no differences in the length of stay, cost, and 30-day unplanned readmissions between both groups. CONCLUSION: In this contemporary observational analysis of patients admitted with high-risk PE undergoing CDT or CDE, the rates of in-hospital mortality, ICH, and non-ICH bleeding events were not different.

BACKGROUND: Chronic immobility is prevalent, especially as people age. However, little is known about venous thromboembolism (VTE) outcomes in this population. OBJECTIVE: To compare the presentation, treatment, and outcomes in chronically immobile (>8 weeks) patients older vs. younger than 75 who presented with VTE. DESIGN: An observational international registry of patients with VTE. PARTICIPANTS: Patients with acute VTE from the "Registro Informatizado Enfermedad TromboEmbolica" (RIETE) registry who were chronically immobile. MAIN MEASURES: Baseline characteristics, presenting signs and symptoms, treatment and outcomes including major bleeding, recurrent VTE, and mortality. KEY RESULTS: Among 4612 immobile patients (mean age 75.7 years, 34% male), 2127 (46%) presented with pulmonary embolism (PE). Patients >75 years presented more often with dyspnea (44% vs. 38%) or altered mental status (23% vs. 8.1%) and less often with chest pain (13% vs. 18%). The median duration of anticoagulation was shorter in older compared with younger patients [126 vs. 169 days]. During the first 90 days of anticoagulation, major bleeding (4.0% vs. 2.2%), PE-related death (2.5% vs. 1.1%), and bleeding-related death (0.78% vs. 0.26%) occurred more frequently among older patients. In 3550 patients who received anticoagulation beyond 90 days, older patients had more major bleeding [4.23 vs. 2.21 events per 100 patient years]. After anticoagulation discontinuation, recurrent VTE and major bleeding occurred in 11.8 and 9.25 and 1.49 and 0.69 events per 100 patient years, respectively, both in similar rates in both groups. In multivariable analysis, after stopping anticoagulation, VTE recurrence was inversely associated with long-term facility residence [OR 0.51 (0.28-0.92)], anemia [OR 0.63 (0.42-0.95)], and anticoagulation duration < 90 days [OR 0.38 (0.27-0.54)]. CONCLUSIONS: Chronically immobilized patients older than 75 years presenting with VTE experience a high rate of adverse events including major bleeding and recurrent VTE. When considering treatment beyond 90 days, we should account for bleeding, recurrence risk, and associated mortality.
