Psychotropic medication use and mortality in patients with acute myocardial infarction complicated by cardiogenic shock

Abstract Funding Acknowledgements Type of funding sources: Foundation. Main funding source(s): The Danish Heart Foundation the Research Foundation of Odense University Hospital & Rigshospitalet. Background The impact of pre-existing mental illness on mortality in patients with acute myocardial infarction complicated by cardiogenic shock (AMICS) remains unclear. Purpose This study aims to assess the relation between pharmacologically treated mental disorders at the time of AMICS admission with patient characteristics and mortality. A surrogate marker for mental illness was defined as having at least one reimbursed prescription for psychotropic medication (Anatomical Therapeutic Chemical (ATC) group and subgroups N05, N06) within one year prior to admission with AMICS. Patients were divided into three therapy categories: None, one ATC subgroup, or two or more ATC subgroups. One-year survivors were further stratified by therapy status one year before admission and one year after discharge. Mortality was assessed at 30 days (5 years for one-year survivors). Kaplan-Meier estimates and univariable and multivariable Cox proportional hazards models were used to assess mortality rates stratified by treatment group. Results Of the cohort, 425 patients (25%) received therapy with psychotropic medication within the previous year at the time of presentation with AMICS. Polypharmacy (two or more ATC N05, N06 subgroups) was identified in 132 patients (8%). In these patients, there was a higher prevalence of comorbidities and a greater proportion of females (42% vs. 21%, p<0.001), compared to no treatment. More patients in the polypharmacy group presented with chest pain (60% vs. 52%, p=0.031), they were less often triaged directly to an invasive center (55% vs. 70%, p<0.001), and 30-day mortality was higher (73% vs. 51%, p<0.001). Among the 712 one-year survivors, 121 (17%) were treated with one or more drugs within one year before and after their AMICS admission. 149 (21%) began receiving therapy in the year following their AMICS admission. 422 (59%) never received psychotropic medication. In an unadjusted Cox model, therapy with two or more drugs, compared to no therapy, was associated with higher 30-day mortality (hazard ratio (HR) 1.77, 95% confidence interval (CI) 1.43-2.19, p<0.001). This association remained significant in multivariable analysis (HR 1.66, 95%CI 1.22-2.26, p=0.001). Among one-year survivors, therapy with one or more drugs before and after AMICS was tied to an almost two-fold increase in five-year mortality (adjusted HR 1.95, 95%CI 1.23-3.10, p=0.004). Conclusions AMICS patients with pharmacologically treated mental illnesses were associated with higher mortality rates, as well as less favorable clinical profiles and treatment patterns. This increased risk remains evident among one-year survivors.

An Exploratory Analysis of Routine Ferritin Measurement Upon Admission and the Prognostic Implications of Low-Grade Ferritinemia During Inflammation

Serum ferritin is usually measured in the presence of anemia or in suspected iron overload syndromes. Ferritin is also an acute-phase protein that is elevated during systemic inflammation. However, the prognostic value of routinely measuring ferritin upon admission to a medical facility is not clear. Therefore, we examined the association between ferritin concentrations measured at the time of hospital admission with 30-day and long-term mortality. We obtained routine ferritin measurements taken within 24 hours of admission in 2859 patients hospitalized in an internal medicine department. Multiple clinical and laboratory parameters were used to assess the association between ferritin and overall mortality during a median follow-up of 15 months (interquartile range [IQR] 8-22). Ferritin levels were associated with increased 30-day mortality rates (odds ratio [OR] 1.04, 95% confidence interval [CI] 1.03-1.06) for each 100 ng/mL increase. Patients with intermediate (78-220 ng/mL) and high (>221 ng/mL) ferritin concentrations (2nd and 3rd tertiles) had higher 30-day mortality rates even after adjustment for age, sex, and existing comorbidities (OR 2.05, 95% CI 1.70-2.5). Long-term overall mortality rates demonstrated a similar pattern across ferritin tertiles (hazard ratio [HR] 1.54, 95% CI 1.39-1.71). Routine admission ferritin concentrations are linearly and independently correlated with excess mortality risk in hospitalized patients, even those with apparently "normal" ferritin concentrations (<300 mg/mL). Thus, low-grade ferritinemia might not be an innocent finding in the context of the inflammatory response. Its potential biological and therapeutic implications warrant future research.

Risk factors and management of gastrointestinal bleeding in patients with or without antiplatelet and anticoagulation therapy: a multicenter real-world prospective study

BackgroundAntiplatelet and anticoagulation drugs complicate acute gastrointestinal bleeding (GIB) patients. Limited data about the risk factors and patient management has been presented. This study explored the association between previous antiplatelet or anticoagulant drug usage and clinical outcomes in GIB patients to improve awareness further and optimize treatment.MethodsWe conducted a multicenter, non-interventional, real-world prospective study in 106 hospitals in 23 provinces in China. GIB patients confirmed in the emergency department were included and were grouped according to previous drug histories. Univariate analysis, multivariate logistic regression, and multivariate stratification models were performed separately to investigate the associations.ResultsA total of 2299 patients (57.23 ± 17.21 years old, 68.3% male) were included, of whom 20.1% and 2.9% received antiplatelet and anticoagulation therapy, respectively. The all-cause 28-day mortality rates in patients without antiplatelet or anticoagulants, patients undergoing antiplatelet treatment, and patients with anticoagulation therapy were 2.8%, 4.6%, and 10.5%, respectively. After adjusting for confounding factors, both antiplatelet [odd ratio (OR), 2.92; 95% confidence interval (CI), 1.48–5.76; p = 0.002] and anticoagulation therapy (OR, 8.87; 95% CI, 3.02–26.02; p < 0.001) were associated with higher 28-day mortality. In the subgroup analysis, blood transfusion, especially red blood cell transfusion, in patients undergoing antiplatelet and anticoagulation therapy was associated with a decreased death risk.ConclusionWe confirmed an association between concurrent antiplatelet or anticoagulation therapy in GIB patients and elevated 28-day mortality. Blood transfusions could improve poor outcomes in such patients.

Clinical characteristics of acute myeloid leukaemia patients with a large number of azurophilic granules: A single-centre retrospective study.

Large amounts of azurophilic granules are considered to be a morphological feature of acute promyelocytic leukaemia (APL). However, a small percentage of acute myeloid leukaemia (AML) patients also have a large number of azurophilic granules. A large cohort of 3210 AML patients in our hospital was screened to identify AML patients who had a large number of azurophilic granules. The clinical parameters of these patients were collected and compared with typical AML patients (control Group 1) and APL patients (control Group 2). The incidence of AML with a large number of azurophilic granules was 1.26%. The fibrinogen and D-dimer levels of patients in the study group were more similar to those of patients in control Group 2, as was the incidence of bleeding events. Additionally, patients in the study group had higher FLT3-ITD and NPM1 mutation rates than patients in control Group 1. Finally, patients in the study group had a higher 30-day mortality rate than those in control Group 2 (24.2% vs. 9.09%) and showed a higher 30-day mortality trend than those in control Group 1. Therefore, we should pay more attention to the prevention of coagulation dysfunction and bleeding events for these patients.

Expanded analysis for patients with acute cholecystitis indicates outcomes vary based on COVID-19 status and treatment modality

BackgroundThe impact of different phases of COVID-19 infection on outcomes from acute calculous cholecystitis is not well understood. Therefore, we examined outcomes of acute cholecystitis during the COVID-19 pandemic, comparing the effect of different treatment modalities as well as COVID-19 infection status. We hypothesized that acute COVID-19 patients would have worse outcomes than COVID-negative patients, but there would be no difference between COVID-negative and COVID-recovered patients. MethodsWe utilized 2020-2023 National COVID Cohort Collaborative data to identify adults with acute calculous cholecystitis. Treatment (antibiotics-only, cholecystostomy tube, or cholecystectomy), and COVID-19 status (negative, active, or recovered) were collected. Treatment failure of non-operative managements was noted. Adjusted analysis using a series of generalized linear models controlled for confounders (age, sex, BMI, Charlson comorbidity index, severity at presentation, and year) to better assess differences in outcomes between treatment groups, as well as between COVID-19 groups. ResultsIn total, 32,433¥ patients were included: 29,749 COVID-negative, 2,112 COVID-active, and 572¥ COVID-recovered. COVID-active had higher rates of sepsis at presentation. COVID-negative more often underwent cholecystectomy. Unadjusted, COVID-active had higher 30-day mortality, 30-day complication, and longer LOS than COVID-negative and COVID-recovered. Adjusted analysis revealed cholecystectomy carried lower odds of mortality for COVID-active and COVID-negative patients, compared with antibiotics or cholecystostomy. COVID-recovered patients’ mortality was unaffected by treatment modality. Treatment failure from antibiotics was more common for COVID-negative patients. ConclusionsAcute cholecystitis outcomes are impacted by phase of COVID-19 infection and treatment modality. Cholecystectomy does not lead to worse outcomes for COVID-active and COVID-recovered patients, compared with non-operative treatments, thus these patients can be considered for cholecystectomy if their physiology is not prohibitive.

Causes and outcomes of non-chemotherapy induced neutropenic fever in hospitalized adults: An observational study.

Neutropenic fever in adults undergoing chemotherapy for cancer treatment is a medical emergency and has been the focus of numerous studies. However, there is a paucity of data about non-chemotherapy induced neutropenic fever (non-CINF). We retrospectively reviewed 383 adults with neutropenic fever hospitalized at one academic medical center between October 2015 and September 2020 to characterize the frequency, causes, and outcomes of non-CINF. Twenty-six percent of cases of neutropenic fever were non-chemotherapy induced. Among these, the major causes of neutropenia were hematologic malignancy, infection, and rheumatologic disease, and the major causes of fever were infections. Patients with non-CINF had a higher 30-day mortality than those with chemotherapy induced neutropenic fever (25% vs 13%, P = .01). Non-CINF constituted > 25% of neutropenic fever events in hospitalized adults and was associated with a high mortality rate.

Adverse outcomes in patients hospitalized with pneumonia at age 60 or more: A prospective multi-centric hospital-based study in India.

Limited data exists regarding risk factors for adverse outcomes in older adults hospitalized with Community-Acquired Pneumonia (CAP) in low- and middle-income countries such as India. This multisite study aimed to assess outcomes and associated risk factors among adults aged ≥60 years hospitalized with pneumonia. Between December 2018 and March 2020, we enrolled ≥60-year-old adults admitted within 48 hours for CAP treatment across 16 public and private facilities in four sites. Clinical data and nasal/oropharyngeal specimens were collected by trained nurses and tested for influenza, respiratory syncytial virus (RSV), and other respiratory viruses (ORV) using the qPCR. Participants were evaluated regularly until discharge, as well as on the 7th and 30th days post-discharge. Outcomes included ICU admission and in-hospital or 30-day post-discharge mortality. A hierarchical framework for multivariable logistic regression and Cox proportional hazard models identified risk factors (e.g., demographics, clinical features, etiologic agents) associated with critical care or death. Of 1,090 CAP patients, the median age was 69 years; 38.4% were female. Influenza viruses were detected in 12.3%, RSV in 2.2%, and ORV in 6.3% of participants. Critical care was required for 39.4%, with 9.9% in-hospital mortality and 5% 30-day post-discharge mortality. Only 41% of influenza CAP patients received antiviral treatment. Admission factors independently associated with ICU admission included respiratory rate >30/min, blood urea nitrogen>19mg/dl, altered sensorium, anemia, oxygen saturation <90%, prior cardiovascular diseases, chronic respiratory diseases, and private hospital admission. Diabetes, anemia, low oxygen saturation at admission, ICU admission, and mechanical ventilation were associated with 30-day mortality. High ICU admission and 30-day mortality rates were observed among older adults with pneumonia, with a significant proportion linked to influenza and RSV infections. Comprehensive guidelines for CAP prevention and management in older adults are needed, especially with the co-circulation of SARS-CoV-2.

Risk factors for progressing to critical illness in patients with hospital-acquired COVID-19.

Risk factors for progression to critical illness in hospital-acquired coronavirus disease 2019 (COVID-19) remain unknown. Here, we assessed the incidence and risk factors for progression to critical illness and determined their effects on clinical outcomes in patients with hospital-acquired COVID-19. This retrospective cohort study analyzed patients admitted to the tertiary hospital between January 2020 and June 2022 with confirmed hospital-acquired COVID-19. The primary outcome was the progression to critical illness of hospital- acquired COVID-19. Patients were stratified into high-, intermediate-, or low-risk groups by the number of risk factors for progression to critical illness. In total, 204 patients were included and 37 (18.1%) progressed to critical illness. In the multivariable logistic analysis, patients with preexisting respiratory disease (OR, 3.90; 95% CI, 1.04-15.18), preexisting cardiovascular disease (OR, 3.49; 95% CI, 1.11-11.27), immunocompromised status (OR, 3.18; 95% CI, 1.11-9.16), higher sequential organ failure assessment (SOFA) score (OR, 1.56; 95% CI, 1.28-1.96), and higher clinical frailty scale (OR, 2.49; 95% CI, 1.62-4.13) showed significantly increased risk of progression to critical illness. As the risk of the groups increased, patients were significantly more likely to progress to critical illness and had higher 28-day mortality. Among patients with hospital-acquired COVID-19, preexisting respiratory disease, preexisting cardiovascular disease, immunocompromised status, and higher clinical frailty scale and SOFA scores at baseline were risk factors for progression to critical illness. Patients with these risk factors must be prioritized and appropriately isolated or treated in a timely manner, especially in pandemic settings.

Outcomes with General Anesthesia Compared to Conscious Sedation for Endovascular Treatment of Medium Vessel Occlusions: Results of an International Multicentric Study.

Optimal anesthetic strategy for the endovascular treatment of stroke is still under debate. Despite scarce data concerning anesthetic management for medium and distal vessel occlusions (MeVOs) some centers empirically support ageneral anesthesia (GA) strategy in these patients. We conducted an international retrospective study of MeVO cases. Apropensity score matching algorithm was used to mitigate potential differences across patients undergoing GA and conscious sedation (CS). Comparisons in clinical and safety outcomes were performed between the two study groups GA and CS. The favourable outcome was defined as amodified Rankin Scale (mRS) 0-2 at 90days. Safety outcomes were 90-days mortality and symptomatic intracranial hemorrhage (sICH). Predictors of afavourable outcome and sICH were evaluated with backward logistic regression. After propensity score matching 668 patients were included in the CS and 264 patients in the GA group. In the matched cohort, either strategy CS or GA resulted in similar rates of good functional outcomes (50.1% vs. 48.4%), and successful recanalization (89.4% vs. 90.2%). The GA group had higher rates of 90-day mortality (22.6% vs. 16.5%, p < 0.041) and sICH (4.2% vs. 0.9%, p = 0.001) compared to the CS group. Backward logistic regression did not identify GA vs CS as apredictor of good functional outcome (OR for GA vs CS = 0.95 (0.67-1.35)), but GA remained asignificant predictor of sICH (OR = 5.32, 95% CI 1.92-14.72). Anaesthetic strategy in MeVOs does not influence favorable outcomes or final successful recanalization rates, however, GA may be associated with an increased risk of sICH and mortality.

Peri-operative outcomes following radical prostatectomy in the setting of advanced prostate cancer.

To compare the peri-operative outcomes of radical prostatectomy (RP) for locally advanced, node-positive, and metastatic prostate cancer (PCa), as determined through pathological staging, using the American College of Surgeons National Surgical Quality Improvement Project. We identified RP procedures performed between 2019 and 2021. Patients were stratified by pathological staging to compare the effect of locally advanced disease (T3-4), node positivity (N+) and metastasis (M+) vs localised PCa (T1-2 N0 M0). Baseline demographics and 30-day outcomes, including operating time, length of hospital stay (LOS), 30-day mortality, readmissions, reoperations, major complications, minor complications and surgery-specific complications, were compared between groups. Pathological staging data were available for 9276 RPs. Baseline demographics were comparable. There was a slightly higher rate of minor complications in the locally advanced cohort, but no significant difference in major complications, 30-day mortality, readmissions, or rectal injuries. Node positivity was associated with longer operating time, LOS, and some slightly increased rates of 30-day complications. RP in patients with metastatic disease appeared to be similarly safe to RP in patients with M0 disease, although it was associated with a longer LOS and slightly increased rates of certain complications. For patients with pathologically determined locally advanced, node-positive, and metastatic PCa, RP appears to be safe, and is not associated with significantly higher rates of 30-day mortality or major complications compared to RP for localised PCa. This study adds to the growing body of literature investigating the role of RP for advanced PCa; further studies are needed to better characterise the risks and benefits of surgery in such patients.

Carotid endarterectomy and transcarotid artery revascularization can be performed with acceptable morbidity and mortality in patients with chronic kidney disease

ObjectivePatients with chronic kidney disease (CKD) are considered a high-risk population, and the optimal approach to the treatment of carotid disease remains unclear. Thus, we compared outcomes following carotid revascularization for patients with CKD by operative approach of carotid endarterectomy (CEA), transfemoral carotid artery stenting (TFCAS), and transcarotid arterial revascularization (TCAR). MethodsThe Vascular Quality Initiative was analyzed for patients undergoing carotid revascularizations (CEA, TFCAS, and TCAR) from 2016 to 2021. Patients with normal renal function (estimated glomular filtration rate >90 mL/min/1.72 m2) were excluded. Asymptomatic and symptomatic carotid stenosis were assessed separately. Preoperative demographics, operative details, and outcomes of 30-day mortality, stroke, myocardial infarction (MI), and composite variable of stroke/death were compared. Multivariable analysis adjusted for differences in groups, including CKD stage. ResultsA total of 90,343 patients with CKD underwent revascularization (CEA, n = 66,870; TCAR, n = 13,459; and TFCAS, n = 10,014; asymptomatic, 63%; symptomatic, 37%). Composite 30-day mortality/stroke rates were: asymptomatic: CEA, 1.4%; TCAR, 1.2%; TFCAS, 1.8%; and symptomatic: CEA, 2.7%; TCAR, 2.3%; TFCAS, 3.7%. In adjusted analysis, TCAR had lower 30-day mortality compared with CEA (asymptomatic: adjusted odds ratio [aOR], 0.4; 95% confidence interval [CI], 0.3-0.7; symptomatic: aOR, 0.5; 95% CI, 0.3-0.7), and no difference in stroke, MI, or the composite outcome of stroke/death in both symptom cohorts. TCAR had lower risk of other cardiac complications compared with CEA in asymptomatic patients (aOR, 0.7; 95% CI, 0.6-0.9) and had similar risk in symptomatic patients. Compared with TFCAS, TCAR patients had lower 30-day mortality (asymptomatic: aOR, 0.5; 95% CI, 0.2-0.95; symptomatic: aOR, 0.3; 95% CI, 0.2-0.4), stroke (symptomatic: aOR, 0.7; 95% CI, 0.5-0.97), and stroke/death (asymptomatic: aOR, 0.7; 95% CI, 0.5-0.97; symptomatic: aOR, 0.6; 95% CI, 0.4-0.7), but no differences in MI or other cardiac complications. Patients treated with TFCAS had higher 30-day mortality (aOR, 1.8; 95% CI, 1.2-2.5) and stroke risk (aOR, 1.3; 95% CI, 1.02-1.7) in symptomatic patients compared with CEA. There were no differences in MI or other cardiac complications. ConclusionsAmong patients with CKD, TCAR and CEA showed rates of stroke/death less than 2% for asymptomatic patients and less than 3% for symptomatic patients. Given the increased risk of major morbidity and mortality, TFCAS should not be performed in patients with CKD who are otherwise anatomic candidates for TCAR or CEA.

Paradigm Shift of Interventional Strategies and Outcomes for Acute Limb Ischemia Post-Pandemic.

We performed a large-scale comparison of patients treated for acute limb ischemia (ALI) in the pre-COVID (2017-2019) and COVID (2020-2022) eras to evaluate changes in interventional strategies and compare factors associated with adverse outcomes. We sought to characterize patient outcomes in an evolving ALI treatment algorithm in response to pandemic-associated presentation delays and rapid technological advancements in mechanical thrombectomy (MT). Using the TriNetX global research network, we conducted a multicenter query across 80 health care organizations (HCOs) spanning 4 countries for patients treated for ALI. Propensity score matching was performed to account for comorbidities. Risk of adverse outcomes within 30 days was calculated for each era, including re-intervention (RI30), major/minor amputation, and death. Patients were then stratified by initial intervention: open revascularization (OR), MT, or catheter-directed thrombolysis and adjunctive endovascular procedures alone (CDT/EP). Risk of adverse outcomes was compared between treatment groups of the same era. After propensity score matching, the pre-COVID era and COVID era cohorts included 7344 patients each. COVID era patients experienced a statistically significant higher risk of 30-day mortality (RR=1.211, p=0.027). Mechanical thrombectomy interventions were performed more frequently in the COVID era (RR=1.314, p<0.0001). Comparing outcomes between treatment groups, MT patients required RI30 more than OR patients (pre-COVID: RR=2.074, p=0.006; COVID: RR=1.600, p=0.025). Open revascularization patients had higher 30-day mortality (pre-COVID: RR=2.368, p<0.0001; COVID: RR=2.013, p<0.0001) and major amputations (pre-COVID: RR=2.432, p<0.0001; COVID: RR=2.176, p<0.0001) than CDT/EP. Pre-COVID CDT/EP patients were at higher risk for RI30 (RR=1.449, p=0.005) and minor amputations (RR=1.500, p=0.010) than OR. The MT group had higher major amputation rates than CDT/EP (pre-COVID: RR=2.043, p=0.019; COVID: RR=1.914, p=0.007). COVID-era MT patients had greater 30-day mortality (RR=1.706, p=0.031) and RI30 (RR=1.544, p=0.029) than CDT/EP. Significant shifts toward an MT-based approach have been observed in the last 3 years. Although MT required more RI30 than OR, there was no associated consequence of mortality and limb salvage. The increased mortality seen among COVID-era patients could be explained by delayed presentation, as well as poorly understood pro-thrombogenic or pro-inflammatory mechanisms related to the first waves of COVID. More research is necessary to determine an optimal treatment algorithm. Comorbid risk factors and severity of ischemia must be carefully considered before selecting an interventional strategy to prevent adverse outcomes and maximize limb salvage. Open revascularization strategies are associated with increased mortality and limb loss compared to less-invasive thrombolytic therapy alone. Mechanical thrombectomy (MT)-based approaches have been increasingly used in the last 3 years. Patients receiving MT are more likely to require reintervention within 30 days.

Five-year outcomes of fenestrated and branched endovascular repair of complex aortic aneurysms based on aneurysm extent

ObjectiveThe aim of this study was to evaluate the 5-year outcomes of fenestrated/branched endovascular aortic repair (F/BEVAR) for the treatment of complex aortic aneurysms stratified by the aneurysm extent. MethodsPatients with the diagnosis of complex aortic aneurysm, who underwent F/BEVAR at a single center were included in this study and retrospectively analyzed. The cohort was divided according to the aneurysm extent, comparing group 1 (types I-III thoracoabdominal aneurysms [TAAAs]), group 2 (type IV TAAAs), and group 3 (juxtarenal [JRAAs], pararenal [PRAAs], or paravisceral [PVAAs] aortic aneurysms). The primary endpoints were 30-day and 5-year survival. The secondary endpoints were technical success, occurrence of spinal cord ischemia, primary patency of the visceral arteries, freedom from target vessel instability, and secondary interventions. ResultsOf 436 patients who underwent F/BEVAR between July 2012 and May 2023, 131 presented with types I to III TAAAs, 69 with type IV TAAAs, and 236 with JRAAs, PRAAs, or PVAAs. All cases were treated under a physician-sponsored investigational device exemption protocol with a patient-specific company-manufactured or off-the-shelf device. Group 1 had significantly younger patients than group 2 or 3 respectively (69.6 ± 8.7 vs 72.4 ± 7.1 vs 73.2 ± 7.3 years; P < .001) and had a higher percentage of females (50.4% vs 21.7% vs 17.8%; P < .001). Prior history of aortic dissection was significantly more common among patients in group 1 (26% vs 1.4% vs 0.9%; P < .001), and mean aneurysm diameter was larger in group 1 (64.5 vs 60.7 vs 63.2 mm; P = .033). Comorbidities were similar between groups, except for coronary artery disease (P < .001) and tobacco use (P = .003), which were less prevalent in group 1. Technical success was similar in the three groups (98.5% vs 98.6% vs 98.7%; P > .99). The 30-day mortality was 4.5%, 1.4%, and 0.4%, in groups 1, 2, and 3, respectively, and was significantly higher in group 1 when compared with group 3 (P = .01). The incidence of spinal cord ischemia was significantly higher in group 1 compared with group 3 (5.3% vs 4.3% vs 0.4%; P = .004). The 5-year survival was significantly higher in group 3 when compared with group 1 (P = .01). Freedom from secondary intervention was significantly higher in group 3 when compared with group 1 (P = .003). At 5 years, there was no significant difference in freedom from target vessel instability between groups or primary patency in the 1652 target vessels examined. ConclusionsLarger aneurysm extent was associated with lower 5-year survival, higher 30-day mortality, incidence of secondary interventions, and spinal cord ischemia. The prevalence of secondary interventions in all groups makes meticulous follow-up paramount in patients with complex aortic aneurysm treated with F/BEVAR.

Baseline perihematomal edema, C-reactive protein, and 30-day mortality are not associated in intracerebral hemorrhage.

The relationship between baseline perihematomal edema (PHE) and inflammation, and their impact on survival after intracerebral hemorrhage (ICH) are not well understood. Assess the association between baseline PHE, baseline C-reactive protein (CRP), and early death after ICH. Analysis of pooled data from multicenter ICH registries. We included patients presenting within 24 h of symptom onset, using multifactorial linear regression model to assess the association between CRP and edema extension distance (EED), and a multifactorial Cox regression model to assess the association between CRP, PHE volume and 30-day mortality. We included 1,034 patients. Median age was 69 (interquartile range [IQR] 59-79), median baseline ICH volume 11.5 (IQR 4.3-28.9) mL, and median baseline CRP 2.5 (IQR 1.5-7.0) mg/L. In the multifactorial analysis [adjusting for cohort, age, sex, log-ICH volume, ICH location, intraventricular hemorrhage (IVH), statin use, glucose, and systolic blood pressure], baseline log-CRP was not associated with baseline EED: for a 50% increase in CRP the difference in expected mean EED was 0.004 cm (95%CI 0.000-0.008, p = 0.055). In a further multifactorial analysis, after adjusting for key predictors of mortality, neither a 50% increase in PHE volume nor CRP were associated with higher 30-day mortality (HR 0.97; 95%CI 0.90-1.05, p = 0.51 and HR 0.98; 95%CI 0.93-1.03, p = 0.41, respectively). Higher baseline CRP is not associated with higher baseline edema, which is also not associated with mortality. Edema at baseline might be driven by different pathophysiological processes with different effects on outcome.

ASCOD phenotyping of acute vertebrobasilar artery occlusion treated by mechanical thrombectomy: insight from the PERSIST registry.

Determining the underlying etiology of acute vertebrobasilar artery occlusion (VBAO) is crucial for selecting an appropriate treatment approach. The authors aimed to investigate the distribution of etiology and the association with functional outcomes in patients with acute VBAO who underwent endovascular treatment in which atherosclerosis, small-vessel disease, cardiac pathology, other causes, and dissection (ASCOD) phenotyping was used. A retrospective study was conducted at 21 centers in China, involving patients with VBAO who received endovascular treatment within 24 hours of the estimated occlusion time. In the ASCOD phenotyping, each phenotype is graded based on the following categories: 1, likely to be causal; 2, uncertain if causal; and 3, unlikely to be causal. The authors defined a single possible cause as a cause graded 1 in a single domain, and multiple possible causes were graded 1 or 2 regardless of overlap. The primary outcome was unfavorable outcome (modified Rankin Scale [mRS] score of 3-6) at 90 days. The secondary outcomes included shift of mRS score at 90 days, 90-day mortality, successful reperfusion, and National Institutes of Health Stroke Scale score at 24 hours. Multivariable regression analysis was used to assess the association between etiological subtypes and functional outcomes. Multivariate competing-risk regression analysis was performed to analyze the association between etiological subtypes and the risk of recurrent stroke. A total of 577 patients were included in this study. Of these, 521 (90%) had a single possible cause. The most common etiology was A1 (382 cases, 73%), followed by C1 (111 cases, 21%) and O1 (28 cases, 5%-in this study the other causes and dissection subtypes were categorized under the umbrella term of "O" causes). Similar patterns were observed in the multiple possible causes. In the baseline characteristics of the cohort, as rescue therapy, stenting was more frequently used in patients in the A1 group than in the C1 group (53.2% vs 41.7%; p < 0.01). The proportion of atherosclerosis-type etiology increased when the occlusion was located more proximally (p < 0.01). Compared to the A1 group, patients in the C1 group had a lower incidence of unfavorable outcome (OR 0.42, 95% CI 0.24-0.73), which was less likely to shift to a worse mRS score (OR 0.60, 95% CI 0.39-0.91). The O1 subtype was not associated with unfavorable outcome (OR 1.35, 95% CI 0.46-4.01), whereas patients with the O1 subtype were more likely to shift to worse mRS score (OR 2.39, 95% CI 1.09-5.25) and to have a higher 90-day mortality rate (OR 2.60, 95% CI 1.07-6.31). Furthermore, there was no significant association between single etiological subtypes and stroke recurrence within 1 year. The most common etiology in patients with VBAO was atherosclerosis, followed by cardiac pathology and other. Compared to the A1 subgroup, the C1 subgroup showed better functional outcomes, whereas the O1 subgroup showed worse outcomes. Additionally, there was no statistically significant difference in the recurrence risk.

High Circulating Dipeptidyl Peptidase 3 Predicts Mortality and Need for Organ Support in Cardiogenic Shock: An Ancillary Analysis of the ACCOST-HH Trial

BackgroundCardiogenic shock (CS) is burdened with high mortality. Efforts to improve outcome are hampered by the difficulty of individual risk stratification and the lack of targetable pathways. Previous studies demonstrated that elevated circulating dipeptidyl peptidase 3 (cDPP3) is an early predictor of short-term outcome in CS, mostly of ischemic origin. Our objective was to investigate the association between cDPP3 and short-term outcomes in a diverse population of patients with CS. Methods and ResultscDPP3 was measured at baseline and after 72 hours in the AdreCizumab against plaCebO in SubjecTs witH cardiogenic sHock (ACCOST-HH) trial. The association of cDPP3 with 30-day mortality and need for organ support was assessed. Median cDPP3 concentration at baseline was 43.2 ng/mL (95% confidence interval [CI], 21.2–74.0 ng/mL) and 77 of the 150 patients (52%) had high cDPP3 over the predefined cutoff of 40 ng/mL. Elevated cDPP3 was associated with higher 30-day mortality (adjusted hazard ratio [aHR] = 1.7; 95% CI, 1.0–2.9), fewer days alive without cardiovascular support (aHR, 3 days [95% CI, 0–24 days] vs aHR, 21 days [95% CI, 5–26 days]; P < .0001) and a greater need for renal replacement therapy (56% vs 22%; P < .0001) and mechanical ventilation (90 vs 74%; P = .04). Patients with a sustained high cDPP3 had a poor prognosis (reference group). In contrast, patients with an initially high but decreasing cDPP3 at 72 hours had markedly lower 30-day mortality (aHR, 0.17; 95% CI, 0.084–0.34), comparable with patients with a sustained low cDPP3 (aHR, 0.23; 95% CI, 0.12–0.41). The need for organ support was markedly decreased in subpopulations with sustained low or decreasing cDPP3. ConclusionsThe present study confirms the prognostic value of cDPP3 in a contemporary population of patients with CS.

A Retrospective Analysis of AngioVac Outcomes at a Tertiary Care Center

BackgroundThe AngioVac system is a vacuum aspiration device approved for removal of right-sided cardiac thrombi. It has also been used for management of right-sided endocarditis in selected cases. Retrospective case series have reported high success rate and acceptable 30-day mortality, but there is limited data regarding outcomes beyond the immediate postoperative period. The purpose of this study is to describe our institution's experience with the AngioVac system for thrombus, vegetation, and tumor removal with a significant improvement over previously reported 1-year survival rates. MethodsA retrospective review of AngioVac cases performed at our tertiary care center from 2016-2022 was done. From 2016-2022, 23 patients were identified, and their outcomes are described. ResultsOur review demonstrates 81.8% procedural success, 100% procedure survival, 90.9% survival to discharge, and 81.8% 30-day survival rates. One-year survival rate was 72.7%. Complications including an 18.2% rate of new vasopressor use, 54.5% rate of transfusion requirement, and 4.5% rate of acute renal failure requiring hemodialysis were identified. Intraprocedural embolization occurred in 1 case requiring venoarterial extracorporeal membrane oxygenation support and thrombectomy. One case was converted to open surgical intervention. ConclusionsOur review further supports the safety and efficacy of minimally invasive vacuum-assisted aspiration systems beyond the immediate postoperative period in intracardiac thrombus, tumor, and right-sided infective endocarditis. Our institution's experience emphasizes a team-based approach including interventional cardiology and cardiothoracic surgery with a standardized imaging approach with transesophageal echocardiogram. Future guidelines are needed to include an algorithmic approach to intracardiac masses.

The CRP troponin test (CTT) stratifies mortality risk in patients with non-ST elevation myocardial infarction (NSTEMI).

The C-reactive protein (CRP)-troponin-test (CTT) comprises simultaneous serial measurements of CRP and cardiac troponin and might reflect the systemic inflammatory response in patients with acute coronary syndrome. We sought to test its ability to stratify the short- and long-term mortality risk in patients with non-ST elevation myocardial infarction (NSTEMI). We examined 1,675 patients diagnosed with NSTEMI on discharge who had at least two successive measurements of combined CRP and cardiac troponin within 48 h of admission. A tree classifier model determined which measurements and cutoffs could be used to best predict mortality during a median follow-up of 3 years [IQR 1.8-4.3]. Patients with high CRP levels ( > 90th percentile, >54 mg/L) had a higher 30-day mortality rate regardless of their troponin test findings (16.7% vs. 2.9%, p < 0.01). However, among patients with "normal" CRP levels ( < 54 mg/L), those who had high troponin levels ( > 80th percentile, 4,918 ng/L) had a higher 30-day mortality rate than patients with normal CRP and troponin concentrations (7% vs. 2%, p < 0.01). The CTT test result was an independent predictor for overall mortality even after adjusting for age, sex, and comorbidities (HR = 2.28 [95% CI 1.56-3.37], p < 0.01 for patients with high troponin and high CRP levels). Early serial CTT results may stratify mortality risk in patients with NSTEMI, especially those with "normal" CRP levels. The CTT could potentially assess the impact of inflammation during myocardial necrosis on the outcomes of patients with NSTEMI and identify patients who could benefit from novel anti-inflammatory therapies.

Development and validation of potential phenotypes of serum electrolyte disturbances in critically ill patients and a Web-based application

BackgroundElectrolyte disturbances are highly heterogeneous and severely affect the prognosis of critically ill patients. Our study was to determine whether data-driven phenotypes of seven electrolytes have prognostic relevance in critically ill patients. MethodsWe extracted patient information from three large independent public databases, and clustered the electrolyte distribution of ICU patients based on the extreme value, median value and coefficient of variation of electrolytes. Three plausible clinical phenotypes were calculated using K-means clustering algorithm as the basic clustering method. MIMIC-IV was considered a training set, and two others have been designated as verification set. The robustness of the model was then validated from different angles, providing dynamic and interactive visual charts for more detailed characterization of phenotypes. Results15,340, 12,445 and 2147 ICU patients with electrolyte records during early ICU stay in MIMIC-IV, eICU-CRD and AmsterdamUMCdb were enrolled. After clustering, three reasonable and interpretable phenotypes are defined as α, β and γ according to the order of clusters. The α and γ phenotype, with significant differences in electrolyte distribution and clinical variables, higher 28-day mortality and longer length of ICU stay (p < 0.001), was further demonstrated by robustness analysis. The α phenotype has significant kidney injury, while the β phenotype has the best prognosis. In addition, the assignment methods of the three phenotypes were developed into a web-based tool for further verification and application. ConclusionsThree different clinical phenotypes were identified that correlated with electrolyte distribution and clinical outcomes. Further validation and characterization of these phenotypes is warranted.

One-stage versus two-stage procedure for the surgical management of patients with acute mesenteric ischemia

Background Damage control surgery (planned second look) is preferred by many surgeons in the management of patients with acute mesenteric ischemia (AMI) with established bowel necrosis. However, some surgeons prefer to perform primary anastomosis during the first operation, making the second look only when indicated. Herein, we compare the perioperative outcomes of the previous two approaches in AMI patients. Patients and methods In this prospective, randomized study, AMI was diagnosed in 74 patients who were divided into group A (one-stage approach) and group B (two-stage approach). Results The one-stage approach spent more operative time compared with the first step of the other approach (110 vs. 70 min, respectively). The planned second look had an average of 75 min, and intestinal resection was done in 35.14% of cases due to advancing ischemia. The incidence of leakage was higher in the one-stage group (32.43%) compared with the other (5.4%), leading to a high reoperation rate in the former. ICU stay was longer with the damage control approach. Nonetheless, no difference was detected regarding the hospitalization period. The one-stage approach was associated with a higher 30-day mortality rate (29.73 vs. 8.11% in the other group). Risk factors for mortality included shock at presentation, prolonged operative time, and postoperative leakage. Conclusion The application of the damage control approach in patients with AMI is of great benefit as it is associated with low leakage rates, less need for reoperation, and less incidence of 30-day mortality compared with the one-stage approach.
