ABSTRACT
High-risk acute pulmonary embolism (PE), defined as acute PE associated with hemodynamic instability, remains a significant contributor to cardiovascular morbidity and mortality in the United States and worldwide. Historically, anticoagulant therapy in addition to systemic thrombolysis has been the mainstays of medical therapy for the majority of patients with high-risk PE. In efforts to reduce the morbidity and mortality, a wide array of interventional and surgical therapies has been developed and employed in the management of these patients. However, the most recent guidelines for the management of PE have reserved the use of these advanced therapies in scenarios where thrombolytic therapy plus anticoagulation are unsuccessful. This is due largely to the lack of prospective, randomized studies in this population. Stemming from this, the approach to treatment of these patients varies widely depending on institutional experience and resources. Furthermore, morbidity and mortality remain unacceptably high in this population, with estimated 30-day mortality of at least 30%. As such, development of a standardized approach to treatment of these patients is paramount to improving outcomes. Early and accurate risk stratification in conjunction with a multidisciplinary team approach in the form of a PE response team is crucial. With the advent of novel therapies for the treatment of acute PE, in addition to the growing availability of and familiarity with mechanical circulatory support systems, such a standardized approach may now be within reach.

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.

OBJECTIVES: The FlowTriever All-Comer Registry for Patient Safety and Hemodynamics (FLASH) is a prospective multi-center registry evaluating the safety and effectiveness of percutaneous mechanical thrombectomy for treatment of pulmonary embolism (PE) in a real-world patient population (NCT03761173). This interim analysis reports outcomes for the first 250 patients enrolled in FLASH. BACKGROUND: High- and intermediate-risk PEs are characterized by high mortality rates, frequent readmissions, and long-term sequelae. Mechanical thrombectomy is emerging as a front-line therapy for PE that enables immediate thrombus reduction while avoiding the bleeding risks inherent with thrombolytics. METHODS: The primary endpoint is a composite of major adverse events (MAE) including device-related death, major bleeding, and intraprocedural device- or procedure-related adverse events at 48 h. Secondary endpoints include on-table changes in hemodynamics and longer-term measures including dyspnea, heart rate, and cardiac function. RESULTS: Patients were predominantly intermediate-risk per ESC guidelines (6.8% high-risk, 93.2% intermediate-risk). There were three MAEs (1.2%), all of which were major bleeds that resolved without sequelae, with no device-related injuries, clinical deteriorations, or deaths at 48 h. All-cause mortality was 0.4% at 30 days, with a single death that was unrelated to PE. Significant on-table improvements in hemodynamics were noted, including an average reduction in mean pulmonary artery pressure of 7.1 mmHg (22.2%, p < 0.001). Patient symptoms and cardiac function improved through follow-up. CONCLUSIONS: These interim results provide preliminary evidence of excellent safety in a real-world PE population. Reported outcomes suggest that mechanical thrombectomy can result in immediate hemodynamic improvements, symptom reduction, and cardiac function recovery.

PURPOSE: To examine nationwide variations in inpatient use of drug-coated balloons (DCBs) for treating femoropopliteal segment occlusive disease and whether DCBs are associated with reduced early out-of-hospital health care utilization. MATERIALS AND METHODS: The study included 24,022 patients who survived hospitalization for femoropopliteal revascularization using DCB angioplasty (n=7850) or uncoated balloon angioplasty (n=16,172) in the 2016-2017 Nationwide Readmissions Database. Differences in patient, hospitalization, and institutional characteristics were compared between treatment strategies. Adjusted logistic regression models were used to examine differences in 6-month rates of readmission, amputation, and repeat intervention. Results are presented as the odds ratio (OR) and 95% confidence interval (CI). RESULTS: Patients treated with DCBs had a higher prevalence of chronic limb-threatening ischemia, diabetes, hypertension, and tobacco use. Revascularization with a DCB was associated with shorter hospitalizations, lower median hospitalization costs, and fewer inpatient lower extremity amputations. Readmissions at 6 months were decreased in patients treated with DCBs compared with uncoated balloon angioplasty (OR 0.90, 95% CI 0.83 to 0.98, p=0.014). The most common reasons for readmission were complications related to procedures (15.4%) and diabetes (15.4%). Compared to patients treated with DCBs, patients treated with uncoated balloon angioplasty were more often readmitted with early procedure-related complications (13.3% vs 17.5%). There were no between-group differences in readmission for sepsis, myocardial infarction, or congestive heart failure. CONCLUSION: DCBs are less often used compared to uncoated balloons during inpatient femoropopliteal procedures. While DCB utilization is associated with more severe comorbidities and advanced peripheral artery disease, readmission rates are decreased through the first 6 months.

Errors in death certification can directly affect the decedent's survivors and the public register. We assessed the effectiveness of an educational seminar targeting frequent and important errors identified by local death certificate (DC) evaluation. Retrospective review of 1500 DCs categorized errors and physician specialty. A 60-minute didactic/case-based seminar was subsequently designed for family medicine physician (FAM) participants, with administration of presurvey, immediate post, and 2-month postsurveys. Most DCs were completed by FAM (73%), followed by internists (18%) and surgeons (3%). Error occurrence (EO) rate ranged between 32 and 75% across all specialities. Family medicine physician experienced in palliative care had the lowest EO rate (32%), significantly lower (P < 0.001) than FAM without interest in palliative care (62%), internal medicine (62%), and surgery (75%). Common errors were use of abbreviations (26%), mechanism as underlying cause of death (23%), and no underlying cause of death recorded (22%). Presurvey participants (n = 72) had an overall EO rate of 72% (64% excluding formatting errors). Immediate postsurvey (n = 75) and 2-month postsurvey (n = 24) participants demonstrated significantly lower overall EO (34% and 24%, respectively), compared with the Pre-S (P < 0.05). A 60-minute seminar on death certification reduced EO rate with perceived long-term effects.

Both catheter-directed thrombolysis (CDT) and ultrasound-assisted thrombolysis (USAT) are novel treatment modalities for patients presenting with acute pulmonary embolism (PE). The objective of this study was to compare clinical and quality-of-life (QOL) outcomes for patients undergoing either treatment modality. We retrospectively studied 70 consecutive patients treated with either CDT or USAT over 3 years at a multicenter health system. The primary clinical efficacy endpoint was right ventricular systolic pressure (RVSP) reduction post-procedurally. Safety endpoints were mortality and bleeding incidents based on Global Utilization of Streptokinase and Tissue Plasminogen Activator for Occluded Arteries (GUSTO) criteria. Long-term QOL was assessed using the 36-Item Short-Form Health Survey (SF-36) via phone interview. Thirty-seven patients (53%) in our study underwent USAT and 33 (47%) patients were treated with conventional CDT. Among all patients studied, 96% had echocardiographic evidence for right ventricular strain on admission. Mean RVSP decreased by 18 ± 13 mmHg in the USAT group post-procedurally as compared to 14 ± 16 mmHg in the CDT group, without significant difference between groups ( p = 0.31). Rates of moderate and severe bleeding were largely identical between USAT and CDT groups (USAT: 3%; CDT: 0%; p = 0.09). There was no death in either group during admission. At long-term follow-up, there was no significant difference in QOL between both treatment modalities in all eight functional domains of SF-36. Our retrospective study demonstrated using USAT over conventional CDT for acute submassive or massive PE did not yield additional clinical, safety, or long-term QOL benefit.

BACKGROUND & PURPOSE: Embolic protection devices (EPD) may provide a mechanism to reduce peri-procedural strokes. They are advocated by consensus guidelines and mandated for Medicare reimbursement. However, outcomes data remain mixed. We aimed to characterize the population of patients undergoing unprotected carotid artery stenting (CAS) and assess the utility of distal filter EPD (F-EPD) in elective CAS. METHODS: We analyzed patients enrolled in the CARE Registry® undergoing CAS between May, 2005 and January, 2012. We assessed the relationship between distal F-EPD use versus no use (No-EPD) and the composite of in-hospital death or stroke (MAE) in unadjusted and 1:3 propensity-matched analyses. RESULTS: Embolic protection was not attempted in a total of 579 out of 13,263 cases performed (4.4%). Patients in the No-EPD group had worse preprocedure neurologic risk factors including higher rates of acute evolving stroke, prior TIA/stroke, symptomatic lesion status, spontaneous carotid artery dissection, and use of general anesthesia intraprocedurally (all Standardized Differences{sd} >10). After exclusion of nonelective cases there was no significant difference in MAE between the No-EPD and F-EPD groups (1.6% vs. 2.3%, sd = 4.72). Additionally, after propensity matching, rates of MAE did not differ between the No-EPD (n = 355) and F-EPD (n = 1065) groups (1.7% vs. 2.5%, sd = 5.87). CONCLUSIONS: Patients selected to undergo unprotected CAS in contemporary practice have high rates of adverse preprocedure neurologic risk factors. Our propensity-matched analysis did not demonstrate evidence of significant benefit or harm associated with use of F-EPD in elective CAS patients.

Venous thromboembolism (VTE), comprising deep venous thrombosis (DVT) and pulmonary embolism (PE), is a prevalent cardiovascular condition, ranking third globally after myocardial infarction and stroke. The risk of VTE rises with age, posing a growing concern in aging populations. Acute PE, with its high morbidity and mortality, emphasizes the need for early diagnosis and intervention. This review explores prognostic factors for acute PE, categorizing it into low-risk, intermediate-risk, and high-risk based on hemodynamic stability and right ventricular strain. Timely classification is crucial for triage and treatment decisions. In the contemporary landscape, low-risk PE patients are often treated with Direct Oral Anticoagulants (DOACS) and rapidly discharged for outpatient follow-up. Intermediate- and high-risk patients may require advanced therapies, such as systemic thrombolysis, catheter-directed thrombolysis, mechanical thrombectomy, and IVC filter placement. The latter, particularly IVC filters, has witnessed increased usage, with evolving types like retrievable and convertible filters. However, concerns arise regarding complications and the need for timely retrieval. This review delves into the role of IVC filters in acute PE management, addressing their indications, types, complications, and retrieval considerations. The ongoing debate surrounding IVC filter use, especially in patients with less conventional indications, reflects the need for further research and data. Despite complications, recent studies suggest that clinically significant issues are rare, sparking discussions on the appropriate and safe utilization of IVC filters in select PE cases. The review concludes by highlighting current trends, gaps in knowledge, and potential avenues for advancing the role of IVC filters in future acute PE management.
ABSTRACT
There is a paucity of data on the cardiovascular implications of monoclonal gammopathy of undetermined significance, especially among hospitalized patients. Our study aimed to investigate the association between MGUS and cardiovascular outcomes in a hospital setting using the National Inpatient Sample database. MGUS patients were sampled using ICD-10 codes. The patients were stratified into two cohorts based on the presence or absence of MGUS. Comorbidities and cardiovascular outcomes were collected using ICD 10 DM codes. CV outcomes were evaluated before and after 1:1 matching for age, gender, and race. Furthermore, a sensitivity analysis was performed on the matched population, which excluded patients with diabetes mellitus, prior myocardial infarction, chronic kidney disease (stages 3-5), dialysis, hypertension, obesity, metabolic syndrome, cancer, antiplatelets, and oral anticoagulant use and was adjusted for smoking, dyslipidemia, and aspirin use to evaluate the cardiovascular outcomes. MGUS patients had more heart failure, atrial fibrillation, venous thromboembolism, aortic aneurysm, aortic stenosis, aortic regurgitation, mitral stenosis, mitral regurgitation, conduction disorder, cor pulmonale, peripheral vascular disease, and acute myocardial infarction. After matching, MGUS was associated with heart failure, atrial fibrillation, venous thromboembolism, aortic stenosis, mitral regurgitation, conduction disorder, cor pulmonale, and peripheral vascular disease. MGUS was linked to a wide spectrum of cardiovascular diseases in an inpatient setting. Further studies are needed to formulate appropriate recommendations for the screening and management of cardiovascular complications in individuals with MGUS.

BACKGROUND: With the widespread use of permanent pacemakers (PPM), and increased mortality associated with pacemaker endocarditis, it is essential to evaluate comorbidities that could potentially increase the risk of infective endocarditis (IE). Heart failure (HF), a common comorbidity, has not been well studied as an independent risk factor for development of IE in individuals with PPM. METHODS: The US National Inpatient Sample database was used to sample individuals with PPM. Patients with concomitant implantable cardioverter defibrillator, acute heart failure, history of endocarditis, intravenous drug use, prosthetic heart valves, or central venous catheter infection were excluded. Propensity matching was performed to match patients with and without HF. Pre- and post-match logistic regression was performed to assess HF as an independent risk factor for IE. A subgroup analysis was performed comparing IE rates between patients with HF with reduced (HFrEF) vs preserved (HFpEF) ejection fraction. RESULTS: Out of 333,571 patients with PPM included in the study, 121,862 (37â¯%) had HF. HF patients were older and had a higher prevalence of females. All comorbidities except for dental disease and cancer were more prevalent in the HF group. Patients with HF were 1.30 times more likely to develop IE [OR: 1.30 (1.16-1.47); pâ¯<â¯0.001]. The two cohorts were then matched for age, gender, and 20 comorbidities using a 1:1 propensity score matching algorithm. After matching, HF was still independently associated with increased risk of IE [OR: 1.62 (1.36-1.93); pâ¯<â¯0.001]. In our sub-group analysis, HFrEF and HFpEF patients had similar IE rates. CONCLUSION: In PPM population, HF was associated with an increased risk of IE compared to those without HF. We hypothesize that HF being a low-flow and high-inflammatory state might have contributed to this increased risk. Larger studies are required to corroborate our findings and evaluate the need for antimicrobial prophylaxis for this population.

Recent American College of Cardiology (ACC), American Heart Association (AHA), American College of Clinical Pharmacy (ACCP), and Heart Rhythm Society (HRS) guidelines suggest that patients with atrial fibrillation (AF) at intermediate to low annual risk of ischemic stroke can benefit from consideration of factors that might modify their risk of stroke. The role of nontraditional risk factors, such as primary hyperparathyroidism (PHPT), remains unexplored. In our study, we investigated the potential association between PHPT and the risk of ischemic stroke in patients with AF. Using data from the Nationwide Inpatient Sample Database, a retrospective cohort study focused on the adult population with AF, we stratified the participants based on PHPT presence. Demographic information, co-morbidities, and hospitalization details were extracted using International Classification of Diseases, Tenth revision codes. Propensity score matching was applied, encompassing over 20 confounding variables, including the risk factors outlined in the CHA2DS2-VASc (Congestive heart failure (C), Hypertension (H), Age ≥75 years (A2), Diabetes Mellitus (D), Stroke/Transient Ischemic Attack (TIA)/Thromboembolism (S2), Vascular disease (V), Age 65-74 years (A), Sex category [female] (Sc)) score. Multivariate logistic regression analysis was performed after matching to assess the independent impact of PHPT as an ischemic stroke risk factor. A total of 2,051 of the identified 395,249 patients with AF had PHPT. The PHPT group had an average age of 74 years and consisted of more women (66.1% vs 53.0%). After matching, it was observed that the PHPT group had longer hospital stays (5 vs 4 days) and higher hospitalization charges ($45,126 vs $36,644). This group exhibited higher rates of ischemic stroke (6.0% vs 4.4%) and mortality (6.3% vs 4.9%). The adjusted outcomes showed a 1.4-fold increased risk for ischemic stroke and a 1.32-fold increased risk for mortality in the PHPT cohort. The subgroup analysis showed a higher incidence of mortality in men with a high CHA2DS2-VASc score. In conclusion, this study highlights a marked association between PHPT and ischemic stroke in patients with AF, independent of the conventional CHA2DS2-VASc score. The potential mechanisms implicated include vascular changes, cardiac dysfunction, and coagulation cascade alterations. The presence of PHPT should be taken into consideration when deciding the assessment of thromboembolic risk.

Background: Acute mortality for high-risk, or massive, pulmonary embolism (PE) is almost 30% even when treated using advanced therapies. This analysis assessed the safety and effectiveness of mechanical thrombectomy (MT) for high-risk PE. Methods: The prospective, multicenter FlowTriever All-comer Registry for Patient Safety and Hemodynamics (FLASH) study is designed to evaluate real-world PE patient outcomes after MT with the FlowTriever System (Inari Medical). In this study, acute outcomes through 30 days were evaluated for the subset of patients with high-risk PE as determined by the sites and following European Society of Cardiology guidelines. An independent medical monitor adjudicated adverse events (AEs), including major AEs: device-related mortality, major bleeding, or intraprocedural device-related or procedure-related AEs. Results: Of the 799 patients in the US cohort, 63 (7.9%) were diagnosed with high-risk PE; 30 (47.6%) patients showed a systolic blood pressure <90 mm Hg, 29 (46.0%) required vasopressors, and 4 (6.3%) experienced cardiac arrest. The mean age of patients with high-risk PE was 59.4 ± 15.6 years, and 34 (54.0%) were women. At baseline, 45 (72.6%) patients were tachycardic, 18 (54.5%) showed elevated lactate levels of ≥2.5 mM, and 21 (42.9%) demonstrated depressed cardiac index of <2 L/min/m2. Immediately after MT, heart rate improved to 93.5 ± 17.9 bpm. Twenty-five (42.4%) patients did not require an overnight stay in the intensive care unit, and no mortalities or major AEs occurred through 48 hours. Moreover, no mortalities occurred in 61 (96.8%) patients followed up through the 30-day visit. Conclusions: In this cohort of 63 patients with high-risk PE, MT was safe and effective, with no acute mortalities reported. Further prospective data are needed in this population.
ABSTRACT
BACKGROUND: The extent and consequences of ischemia in patients with chronic limb-threatening ischemia (CLTI) may change rapidly, and delays from diagnosis to revascularization may worsen outcomes. We sought to describe the association between time from diagnosis to endovascular lower extremity revascularization (diagnosis-to-limb revascularization [D2L] time) and clinical outcomes in outpatients with CLTI. METHODS AND RESULTS: In the CLIPPER cohort, comprising patients between 66 and 86 years old diagnosed with CLTI betweeen 2010 and 2019, we used Medicare claims data to identify patients who underwent outpatient endovascular revascularization within 180 days of diagnosis. We described the risk-adjusted association between D2L time and clinical outcomes. Among 1 130 065 patients aged between 66 and 86 years with CLTI, 99 221 (8.8%) underwent outpatient endovascular lower extremity revascularization within 180 days of their CLTI diagnosis. Among patients with D2L time <30 days, there was no association between D2L time and all-cause death or major lower extremity amputation. However, among patients with D2L time >30 days, each additional 10-day increase in D2L time was associated with a 2.5% greater risk of major amputation (hazard ratio, 1.025 [95% CI, 1.014-1.036]). There was no association between D2L time and all-cause death. CONCLUSIONS: A delay of >30 days from CLTI diagnosis to lower extremity endovascular revascularization was associated with an increased risk of major lower extremity amputation among patients undergoing outpatient endovascular revascularization. Improving systems of care to reduce D2L time could reduce amputations.

BACKGROUND: Supra-normal ankle brachial index (ABI) (>1.40), poses diagnostic challenges to determine the presence, location, and severity of peripheral artery disease (PAD). The anatomic distribution of PAD in patients with elevated ABI has not been previously described. METHODS: A retrospective review of all patients referred to the Massachusetts General Hospital vascular diagnostic laboratory from 5 January 2006 to 12 January 2011 who had both a supra-normal ABI and contrast arteriography (CA) within 3 months of each other is reported. Angiographic patterns were described using the Trans Atlantic Inter Society Consensus II (TASC II) classification. RESULTS: One-hundred sixteen limbs were analyzed in 92 patients. Mean age was 71.6 years (± 11.2); 81.5% (75/92) were male; 85.9% Caucasian (79/92); 67.4% diabetics (62/92); 78.3% hypertensive (72/92); 67.4% hypercholesterolemic (62/92); and 64.1% were current or former tobacco users (59/92). Chronic hemodialysis was present in 18.5% (17/92) and 15.2% (14/92) received chronic corticosteroids. Intermittent claudication was present in 46.7% (43/92) and critical limb ischemia in 52.2% (48/92). Aortoiliac, femoral and infra-popliteal involvement per angiography occurred in 14.9% (15/101), 56.1% (60/107), and 84.0% (84/100), respectively. Multilevel disease was present in 48.8% (42/86) of patients. PAD was absent in 4.7% (4/86) of patients. Toe brachial index <0.7 was found in 92% (92/100) of patients with angiographically confirmed PAD. CONCLUSION: In symptomatic patients referred to a vascular laboratory who were found to have supra-normal ABI, nearly one half exhibited multilevel PAD, and over 80% had infrapopliteal involvement. A supra-normal ABI in such patients mandates evaluation for the presence and extent of PAD.

Atrial fibrillation (AF) is the most common arrhythmia and increases with age. This rising prevalence of AF is contributing to an increasing public health and economic burden. The 2018 Healthcare Cost and Utilization Project National Inpatient Sample dataset was used. All patients ≥15 years with a principal discharge diagnosis of AF were included. The patient population was divided into an "older" cohort (aged ≥65 years) and a "younger" (aged <65 years). Desired outcomes included hospital length of stay, discharge disposition, hospital charges, and in-hospital mortality. A generalized linear mixed model was used to calculate hospitalization rates for the "younger" and "older" groups. We identified 896,328 AF hospitalizations. Younger patients (18.1%) were more likely to be male (65.5% vs 49.9%), to smoke (21.6% vs 6.1%), and to use alcohol (9.7% vs 2.1%). Older patients were more likely to have heart failure (49.6% vs 43.9%) and hypertension (84.6% vs 76.1%). Hospitalization rates increased with increasing age groups. Older patients had higher in-hospital mortality (4.6% vs 2.9%) and were more likely to be discharged to another facility (31.6% vs 13.2%). AF hospitalization rates vary between hospitals across the United States. Hospital divisions with greater than expected admissions for AF, when compared with the national mean, were driven by higher "older" patient hospitalizations. In conclusion, older patients account for most AF hospitalizations. Older patients have higher AF morbidity and mortality. Hospitalization rates for AF increase with increasing increments of age.

BACKGROUND: Patients with acute pulmonary embolism (PE) and hypotension (high-risk PE) have high mortality. Cardiogenic shock can also occur in nonhypotensive or normotensive patients (intermediate-risk PE) but is less well characterized. OBJECTIVES: The authors sought to evaluate the prevalence and predictors of normotensive shock in intermediate-risk PE. METHODS: Intermediate-risk PE patients in the FLASH (FlowTriever All-Comer Registry for Patient Safety and Hemodynamics) registry undergoing mechanical thrombectomy with the FlowTriever System (Inari Medical) were included. The prevalence of normotensive shock (systolic blood pressure ≥90 mm Hg but cardiac index ≤2.2 L/min/m2) was assessed. A composite shock score consisting of markers of right ventricular function and ischemia (elevated troponin, elevated B-type natriuretic peptide, moderately/severely reduced right ventricular function), central thrombus burden (saddle PE), potential additional embolization (concomitant deep vein thrombosis), and cardiovascular compensation (tachycardia) was prespecified and assessed for its ability to identify normotensive shock patients. RESULTS: Over one-third of intermediate-risk PE patients in FLASH (131/384, 34.1%) were in normotensive shock. The normotensive shock prevalence was 0% in patients with a composite shock score of 0 and 58.3% in those with a score of 6 (highest score). A score of 6 was a significant predictor of normotensive shock (odds ratio: 5.84; 95% CI: 2.00-17.04). Patients showed significant on-table improvements in hemodynamics post-thrombectomy, including normalization of the cardiac index in 30.5% of normotensive shock patients. Right ventricular size, function, dyspnea, and quality of life significantly improved at the 30-day follow-up. CONCLUSIONS: Although hemodynamically stable, over one-third of intermediate-risk FLASH patients were in normotensive shock with a depressed cardiac index. A composite shock score effectively further risk stratified these patients. Mechanical thrombectomy improved hemodynamics and functional outcomes at the 30-day follow-up.

Background: Cardiovascular disease (CVD) is the leading cause of mortality in kidney transplant (KT) patients. The perceived risk of contrast-induced nephropathy (CIN) may create a reluctance to perform coronary angiography in patients presenting with non-ST segment elevation myocardial infarction (NSTEMI). Methods: National Inpatient Sample (NIS) Database was used to sample individuals presenting with NSTEMI. Patients were stratified into KT and Non-KT cohorts. Outcomes included left heart catheterization rates, mortality, arrhythmias, acute kidney injury/acute renal failure (AKI/ARF), and extended length of hospital stay (ELOS) (>72 h). Propensity matching (1:1 ratio) and regression analyses were performed. Results: Out of 336,354 patients with NSTEMI, 742 patients were in the KT group. KT patients were less likely to have LHC relative to non-KT patients (22.0 % vs 18.3 %); a difference that persisted on post-match analysis (27.1 % vs 19.4 %). On pre-match analysis, KT transplant patients that underwent LHC had lower mortality (10.3 % vs 0.7 %), AKI/ARF (44.6 % vs 27.9 %), arrhythmias (30.4 % vs 20.6 %) and lower ELOS (58.6 % vs 41.9 %). Post-match, KT cohort patient that underwent LHC had lower arrhythmias (OR:0.60[0.38-0.96]), AKI/ARF (OR = 0.51[0.34-0.77]), ELOS (OR:0.49[0.34-0.73]). Conclusion: KT patients underwent LHC much less frequently than their non-KT counterparts for NSTEMI. Coronary angiography and subsequent revascularization were associated with a significant decrease in morbidity and mortality. This theorized risk of CIN should not outweigh the benefit of LHC in KT patients.
ABSTRACT
Background: Mechanical thrombectomy provides rapid hemodynamic improvements after acute pulmonary embolism (PE), but long-term benefits are uncertain. Methods: FlowTriever All-comer Registry for Patient Safety and Hemodynamics is a prospective, single-arm, multicenter registry of patients with acute PE treated with the FlowTriever System (Inari Medical). Six-month outcomes including modified Medical Research Council dyspnea scores (MMRCD), right ventricular (RV) function, 6-minute walk test distances, and PE quality-of-life scores (QoL) were assessed. Results: In total, 799 patients were enrolled and 75% completed the study with a mean follow-up of 204 ± 46 days. Demographic characteristics included 54.1% men, mean age of 61.2 years, 77.1% intermediate-high-risk PE, and 8.0% high-risk PE. All-cause mortality was 4.6% at study completion. The proportion of patients with normal echocardiographic RV function increased from 15.1% at baseline to 95.1% at 6 months (P < .0001). MMRCD score improved from 3.0 at baseline to 0.0 at 6 months (P < .0001). 6-minute walk test distances increased from 180 m at 48 hours to 398 m at 6 months (P < .001). Median PE QoL total scores were 9.38 at 30 days and 4.85 at 6 months (P < .001). Prevalence of site-reported chronic thromboembolic pulmonary hypertension was 1.0% and chronic thromboembolic disease was 1.9%. Conclusions: In this large diverse group of PE patients, 6-month all-cause mortality, chronic thromboembolic pulmonary hypertension, and chronic thromboembolic disease were low following thrombectomy with the FlowTriever system. Significant improvements in RV function, patient symptoms, exercise capacity, and QoL were observed at 6 months, suggesting that rapid extraction of thrombus may prevent long-term sequelae in patients with PE.
