    الوصف: Background Inadequate decongestion is common in hospitalized heart failure (HF) patients and may contribute to readmissions. Our purpose was to use remote dielectric sensing (ReDS) technology to measure lung congestion at discharge in patients admitted with acute HF and to see if a device-targeted intervention could reduce HF readmission rates. Methods We conducted a prospective pilot study of patients admitted with acute decompensated HF randomized to receive standard therapy or ReDS-guided therapy to determine the timing of hospital discharge based on the amount of lung congestion present after diuresis. ReDS measurement was performed for all patients once they were deemed ready for discharge. Patients in the treatment arm with residual lung congestion defined by ReDS ≥39% had HF consultation and further diuresis. Results Of 108 HF patients (50% male, age 73.6 ± 12.6 years, BMI 29.3 ± 4.3 kg/m2, EF 38.5 ± 15.1%, BNP 1138 ± 987 pg/mL), 32% demonstrated residual lung congestion at the time of proposed hospital discharge. ReDS guided therapy triggered additional diuresis in 30% (18/60) of the patients in the treatment arm (average weight loss 5.6 pounds, p = 0.02). 30-day HF readmission rates were similar in the treatment and the control arms (1.7% vs 4.2%; p = 0.44). Patients discharged as planned with residual lung congestion with ReDS ≥39% had higher 30-day readmission rate compared to patients who were adequately decongested at discharge with ReDS Conclusion In our single-center cohort, ReDS testing demonstrated that 32% of HF patients deemed ready for discharge have clinically significant residual lung congestion which was associated with a higher risk of readmission. ReDS-guided management was associated with significant decongestion but not a reduction in HF readmissions in this sample.

    الوصف: Background Hyperkalemia (HK) is common and associated with mortality. Our purpose was to determine if the rapid correction of elevated serum potassium level (K+) was associated with reduced mortality in emergency department (ED) patients. Methods Design: We reviewed the electronic medical records (EMR) of ED patients with HK (K+ ≥ 5.5 mEq/L) from 10/2016–10/2017. Setting: Large, academic ED. Participants: Adult ED patients presenting with hyperkalemia. Main outcomes and measures: The main outcome was in-hospital mortality. We compared outcomes of patients whose K+ normalized (dropped below 5.5 mEq/L) with those whose K+ did not normalize using chi-square and multivariate analyses to determine the associations between predictor variables and outcomes. Results From 114,977 ED visits, 1033 patients (0.9%, 95%CI 0.85–0.95%) had HK. Their mean (SD) age was 60 (26) years and 58% were male. Of these, 884 had a second K+ measured within a median (IQR) of 5 (3–8) hours. Mortality and admission rates were higher in patients with HK vs. those with normal K+ (8.5% vs. 0.8%, P Conclusions Normalization of K+ during the ED stay in patients with HK is associated with a 50% mortality reduction. Efforts to rapidly identify and treat HK in the ED are needed.

    الوصف: Background and Purpose: Risks, sites, and predictors of major bleeding during antithrombotic therapies have not been well defined for patients with recent embolic stroke of undetermined source. Methods: Exploratory analysis of major bleeds defined by International Society of Thrombosis and Hemostasis criteria occurring among 7213 participants in international NAVIGATE (New Approach Rivaroxaban Inhibition of Factor Xa in a Global Trial) embolic stroke of undetermined source randomized trial comparing rivaroxaban 15 mg daily with aspirin 100 mg daily. Results: During a median follow-up of 11 months, 85 major bleeds occurred. The most frequent site was gastrointestinal (38%), followed by intracranial (29%). Assignment to rivaroxaban (hazard ratio [HR], 2.7 [95% CI, 1.7–4.3]), East Asia region (HR, 2.5 [95% CI, 1.6–3.9]), systolic blood pressure ≥160 mm Hg (HR, 2.2 [95% CI, 1.2–3.8]), and reduced estimated glomerular filtration rate (HR, 1.2 per 10 mL/min per 1.73 m 2 decrease, [95% CI, 1.0–1.3]) were independently associated with presence of major bleeds. Five (6%) were fatal. Among 15 patients with intracerebral hemorrhage, 2 (13%) were fatal. There was no evidence of an early high-risk period following initiation of rivaroxaban. The annualized rate of intracerebral hemorrhage was 6-fold higher among East Asian participants (0.67%) versus all other regions (0.11%; HR, 6.3 [95% CI, 2.2–18.0]). Distribution of bleeding sites was similar for rivaroxaban and aspirin. Conclusions: Among embolic stroke of undetermined source patients participating in an international randomized trial, independent predictors of major bleeding were assignment to rivaroxaban, East Asia region, increased systolic blood pressure, and impaired renal function. East Asia as a region was strongly associated with risk of intracerebral hemorrhage. Estimated glomerular filtration rate should be a consideration for stratifying bleeding risk.

    الوصف: Background: We conducted a secondary analysis of changes in the Kansas City Cardiomyopathy Questionnaire (KCCQ)-12 over 30 days in a randomized trial of self-care coaching versus structured usual care in patients with acute heart failure who were discharged from the emergency department. Methods: Patients in 15 emergency departments completed the KCCQ-12 at emergency department discharge and at 30 days. We compared change in KCCQ-12 scores between the intervention and usual care arms, adjusted for enrollment KCCQ-12 and demographic characteristics. We used linear regression to describe changes in KCCQ-12 summary scores and logistic regression to characterize clinically meaningful KCCQ-12 subdomain changes at 30 days. Results: There were 350 patients with both enrollment and 30-day KCCQ summary scores available; 166 allocated to usual care and 184 to the intervention arm. Median age was 64 years (interquartile range, 55–70), 37% were female participants, 63% were Black, median KCCQ-12 summary score at enrollment was 47 (interquartile range, 33–64). Self-care coaching resulted in significantly greater improvement in health status compared with structured usual care (5.4-point greater improvement, 95% CI, 1.12–9.68; P =0.01). Improvements in health status in the intervention arm were driven by improvements within the symptom frequency (adjusted odds ratio, 1.62 [95% CI, 1.01–2.59]) and quality of life (adjusted odds ratio, 2.39 [95% CI, 1.46–3.90]) subdomains. Conclusions: In this secondary analysis, patients with acute heart failure who received a tailored, self-care intervention after emergency department discharge had clinically significant improvements in health status at 30 days compared with structured usual care largely due to improvements within the symptom frequency and quality of life subdomains of the KCCQ-12.

    الوصف: High-sensitivity cardiac troponin (hs-cTn) assays have different analytic characteristics.The goal of this study was to quantify differences between assays for common analytical benchmarks and to determine whether they may result in differences in the management of patients with suspected acute coronary syndrome (ACS).The authors included patients with suspected ACS enrolled in the ROMICAT (Rule Out Myocardial Infarction/Ischemia Using Computer Assisted Tomography) I and II trials, with blood samples taken at emergency department presentation (ROMICAT-I and -II) or at 2 and 4 h thereafter (ROMICAT-II). hs-cTn concentrations were measured using 3 assays (Roche Diagnostics, Elecsys 2010 platform; Abbott Diagnostics, ARCHITECT i2000SR; Siemens Diagnostics, HsVista). Per blood sample, we determined concordance across analytic benchmarks (limit of detection [LOD]/LOD-99th percentile/99th percentile). Per-patient, the authors determined concordance of management recommendations (rule-out/observe/rule-in) per the 0/2-h algorithm, and their association with diagnostic test findings (coronary artery stenosis50% on coronary computed tomography angiography or inducible ischemia on perfusion imaging) and ACS.Among 1,027 samples from 624 patients (52.8 ± 10.0 years; 39.4% women), samples were classified as LOD (56.3% vs. 10.4% vs. 41.2%; p 0.001), LOD-99th percentile (36.5% vs. 83.5% vs. 52.6; p 0.001),99th percentile (7.2% vs. 6.0% vs. 6.2%) by Roche, Abbott, and Siemens, respectively. A total of 37.4% (n = 384 of 1,027) of blood samples were classified into the same analytical benchmark category, with low concordance across benchmarks (LOD 11.1%; LOD-99th percentile 29.3%;99th percentile 43.6%). Serial samples were available in 242 patients (40.1% women; mean age: 52.8 ± 8.0 years). The concordance of management recommendations across assays was 74.8% (n = 181 of 242) considering serial hs-cTn measurements. Of patients who were recommended to discharge, 19.6% to 21.1% had positive diagnostic test findings and 2.8% to 4.3% had ACS at presentation.Caregivers should be aware that there are significant differences between hs-cTn assays in stratifying individual samples and patients with intermediate likelihood of ACS according to analytical benchmarks that may result in different management recommendations.

    الوصف: Background and aims We aimed to examine the prevalence, demographics, clinical outcomes and economic burden of hospitalizations for patients with PAD. Methods Using the National Inpatient Sample, we retrospectively evaluated patients hospitalized with PAD in 2014. Hospitalizations in patients with PAD were identified by the presence of an International Classification of Diseases-9th Revision (ICD-9) diagnosis code of 440.20–440.24. We calculated hospitalization rates/100,000 patients, the proportion of hospitalizations with a major adverse limb event (MALE), as well as minor amputation, mortality, median (interquartile range) length-of-stay (LOS) and treatment costs (in 2017 US$). A separate analysis of hospitalizations of patients with clinical limb ischemia defined as Fontaine class III or IV PAD (440.22, resting pain; 440.23–440.24, ulcers or gangrene) was also performed. Results We identified 286,160 hospitalizations for patients with PAD. The rate of hospitalizations for PAD was 89.5/100,000, with 137,050 (or 45%) of these having Fontaine class III-IV disease. The proportion of hospitalizations resulting in MALE, major or minor lower extremity amputation or in-hospital death was 45.8%, 8.9%, 8.2% and 3.1%, respectively. Median hospital LOS was 5 (3, 9) days and costs were $15,755 ($8972, $27,800), resulting in an annual cost burden for hospitalization of patients with PAD of ∼$6.31 billion. In hospitalizations of Fontaine class III-IV PAD, MALE, major and minor amputation and death occurred in 60.9%, 16.8%, 15.8% and 3.3% of cases, respectively. Median LOS and costs were 7 (4, 11) days and $18,984 ($10,913, $31,816). Conclusions Hospitalizations of patients with PAD represent a substantial medical and financial burden for patients and the US healthcare system.

    الوصف: Summary Pulmonary embolism (PE) is the most feared clinical presentation of venous thromboembolism (VTE). Patients with PE have traditionally been treated in hospital; however, many are at low risk of adverse outcomes and current guidelines suggest outpatient treatment as an option. Outpatient treatment of PE offers several advantages, including reduced risk of hospital‐acquired conditions and potential cost savings. Despite this, patients with low‐risk PE are still frequently hospitalized for treatment. This narrative review summarizes current guideline recommendations for the identification of patients with low‐risk PE who are potentially suitable for outpatient treatment, using prognostic assessment tools (e.g. the Pulmonary Embolism Severity Index [PESI] and simplified PESI) and clinical exclusion criteria (e.g. Hestia criteria) alone or in combination with additional cardiac assessments. Treatment options are discussed along with recommendations for the follow‐up of patients managed in the non‐hospital environment. The available data on outpatient treatment of PE are summarized, including details on patient selection, anticoagulant choice, and short‐term outcomes in each study. Accumulating evidence suggests that outcomes in patients with low‐risk PE treated as outpatients are at least as good as, if not better than, those of patients treated in the hospital. With mounting pressures on health care systems worldwide, increasing the proportion of patients with PE treated as outpatients has the potential to reduce health care burdens associated with VTE.

    الوصف: Background and Purpose: Optimal secondary prevention for patients with embolic stroke of undetermined source (ESUS) remains unknown. We aimed to assess whether high-sensitivity cardiac troponin T (hs-cTnT) levels are associated with major vascular events and whether hs-cTnT may identify patients who benefit from anticoagulation following ESUS. Methods: Data were obtained from the biomarker substudy of the NAVIGATE ESUS trial, a randomized controlled trial testing the efficacy of rivaroxaban versus aspirin for secondary stroke prevention in ESUS. Patients were dichotomized at the hs-cTnT upper reference limit (14 ng/L, Gen V, Roche Diagnostics). Cox proportional hazard models were computed to explore the association between hs-cTnT, the combined cardiovascular end point (recurrent stroke, myocardial infarction, systemic embolism, cardiovascular death), and recurrent ischemic stroke. Results: Among 1337 patients enrolled at 111 participating centers in 18 countries (mean age 67±9 years, 61% male), hs-cTnT was detectable in 95% and at/above the upper reference limit in 21%. During a median follow-up of 11 months, the combined cardiovascular end point occurred in 68 patients (5.0%/y, rivaroxaban 28 events, aspirin 40 events; hazard ratio, 0.67 [95% CI, 0.41–1.1]), and recurrent ischemic stroke occurred in 50 patients (4.0%/y, rivaroxaban 16 events, aspirin 34 events, hazard ratio 0.45 [95% CI, 0.25–0.81]). Annualized combined cardiovascular end point rates were 8.2% (9.5% rivaroxaban, 7.0% aspirin) for those above hs-cTnT upper reference limit and 4.8% (3.1% rivaroxaban, 6.6% aspirin) below with a significant treatment modification ( P =0.04). Annualized ischemic stroke rates were 4.7% above hs-cTnT upper reference limit and 3.9% below, with no suggestion of an interaction between hs-cTnT and treatment ( P =0.3). Conclusions: In patients with ESUS, hs-cTnT was associated with increased cardiovascular event rates. While fewer recurrent strokes occurred in patients receiving rivaroxaban, outcomes were not stratified by hs-cTn results. Our findings support using hs-cTnT for cardiovascular risk stratification but not for decision-making regarding anticoagulation therapy in patients with ESUS.

    الوصف: Aims Recent data from national registries suggest that acute heart failure (AHF) outcomes might vary in men and women, however, it is not known whether this observation is universal. The aim of this study was to evaluate the association of biological sex and 1-year all-cause mortality in patients with AHF in various regions of the world. Methods and results We analysed several AHF cohorts including GREAT registry (22 523 patients, mostly from Europe and Asia) and OPTIMIZE-HF (26 376 patients from the USA). Clinical characteristics and medication use at discharge were collected. Hazard ratios (HRs) for 1-year mortality according to biological sex were calculated using a Cox proportional hazards regression model with adjustment for baseline characteristics (e.g. age, comorbidities, clinical and laboratory parameters at admission, left ventricular ejection fraction). In the GREAT registry, women had a lower risk of death in the year following AHF [HR 0.86 (0.79–0.94), P Conclusion Globally women with AHF have a lower 1-year mortality and less evidenced-based treatment than men. Differences among countries need further investigation. Our findings merit consideration when designing future global clinical trials in AHF.
