Differences between patients hospitalized for heart failure with reduced ejection fraction (HFrEF) vs HF with preserved EF (HFpEF) are not well-characterized, particularly as pertains to in-hospital decongestion and longitudinal patient-reported outcomes. The objective of this analysis was to compare patient-reported and clinical outcomes between patients hospitalized with HFrEF vs HFpEF.The Acute Study of Clinical Effectiveness of Nesiritide in Decompensated Heart Failure (ASCEND-HF) trial enrolled 7141 patients hospitalized for HF with reduced or preserved EF. We assessed the association between an EF ≤ 40% vs an EF40% with in-hospital decongestion, risk of rehospitalization and mortality, and quality of life as measured by the EuroQOL 5 Dimensions (EQ-5D). Among 5800 patients (81%) with complete EF data, 4782 (82%) had an EF ≤40% and 1018 (18%) had an EF40%. Both groups demonstrated similar rates of decongestion by weight change and urine volume through 24 hours, a similar risk of 30-day mortality and HF rehospitalization, and a similar 180-day mortality. Patients with HFpEF had worse EQ-5D scores at hour 24 (median 0.76, [interquartile range (IQR) 0.51-0.84] vs 0.78 [IQR 0.57-0.84]; P = .01) that persisted through discharge (0.81 [IQR 0.69-0.86] vs 0.83 [IQR 0.71-1.00]; P.001) and the 30-day follow-up (0.78 [IQR 0.60-0.85] vs 0.83 [IQR 0.71-1.00]; P.001). After adjustment, these differences were attenuated and not statistically significant.In this large, multinational cohort of patients hospitalized for HF, patients with an EF ≤ 40% vs an EF40% experienced similar in-hospital decongestion and postdischarge clinical outcomes. Patients with an EF40% reported worse in-hospital and postdischarge patient-reported health status, but these measures were similar to HFrEF after accounting for other clinical factors.

Although atrial fibrillation (AF) frequently coexists with heart failure with preserved ejection fraction (HFpEF), few data are available evaluating AF-specific care patterns and post-discharge outcomes in patients hospitalized for HFpEF. We evaluated AF-specific medical therapies and post-discharge outcomes among patients hospitalized for heart failure with mildly reduced ejection fraction (HFmrEF) or HFpEF by AF history.Trends in AF prevalence were evaluated among patients hospitalized for HFmrEF or HFpEF in the Get With The Guidelines-Heart Failure Registry from 2014 to 2020. Among those with linked Centers for MedicareMedicaid Services post-discharge data, we assessed associations of AF with 12-month outcomes and determined trends in post-discharge prescriptions. Among 429 464 patients (median age 76 years [interquartile range 65-85], 57% women), 216 486 (50%) had a history of AF. Over time, the proportion of patients with AF increased slightly. Among the 79 895 patients with post-discharge data, AF was independently associated with higher risk of mortality and all-cause readmissions at 12 months, with stronger associations in HFpEF than in HFmrEF (mortality hazard ratio [HR] 1.13, 95% confidence interval [CI] 1.09-1.16 vs. HR 1.03, 95% CI 0.97-1.10; pPrevalence of AF is rising among patients hospitalized with HFpEF. Those with comorbid AF face elevated post-discharge risks of death and rehospitalization. Current use of pharmacological rhythm control is low.

BACKGROUND: Existing data and clinical trials could not determine whether faster intravenous thrombolytic therapy (IVT) translates into better long-term functional outcomes after acute ischemic stroke among those treated with endovascular thrombectomy (EVT). Patient-level national data can provide the required large population to study the associations between earlier IVT, versus later, with longitudinal functional outcomes and mortality in patients receiving IVT+EVT combined treatment. METHODS: This cohort study included older US patients (age ≥65 years) who received IVT within 4.5 hours or EVT within 7 hours after acute ischemic stroke using the linked 2015 to 2018 Get With The Guidelines–Stroke and Medicare database (38 913 treated with IVT only and 3946 with IVT+EVT). Primary outcome was home time, a patient-prioritized functional outcome. Secondary outcomes included all-cause mortality in 1 year. Multivariate logistic regression and Cox proportional hazards models were used to evaluate the associations between door-to-needle (DTN) times and outcomes. RESULTS: Among patients treated with IVT+EVT, after adjusting for patient and hospital factors, including onset-to-EVT times, each 15-minute increase in DTN times for IVT was associated with significantly higher odds of zero home time in a year (never discharged to home) (adjusted odds ratio, 1.12 [95% CI, 1.06–1.19]), less home time among those discharged to home (adjusted odds ratio, 0.93 per 1% of 365 days [95% CI, 0.89–0.98]), and higher all-cause mortality (adjusted hazard ratio, 1.07 [95% CI, 1.02–1.11]). These associations were also statistically significant among patients treated with IVT but at a modest degree (adjusted odds ratio, 1.04 for zero home time, 0.96 per 1% home time for those discharged to home, and adjusted hazard ratio 1.03 for mortality). In the secondary analysis where the IVT+EVT group was compared with 3704 patients treated with EVT only, shorter DTN times (≤60, 45, and 30 minutes) achieved incrementally more home time in a year, and more modified Rankin Scale 0 to 2 at discharge (22.3%, 23.4%, and 25.0%, respectively) versus EVT only (16.4%, P 60 minutes. CONCLUSIONS: Among older patients with stroke treated with either IVT only or IVT+EVT, shorter DTN times are associated with better long-term functional outcomes and lower mortality. These findings support further efforts to accelerate thrombolytic administration in all eligible patients, including EVT candidates.

BackgroundPatients with ischemic stroke and concomitant coronavirus 2019 (COVID-19) infection have worse outcomes than those without this infection. However, research on the impact of COVID-19 infection on outcomes following hemorrhagic stroke remains limited. We aim to study whether concomitant COVID-19 infection leads to worse outcomes in spontaneous intracerebral hemorrhage (ICH).DesignWe conducted an observational study using data from Get With The Guidelines® Stroke, an ongoing, multi-center, nationwide quality assurance registry.MethodsWe implemented a two-stage design: first, we compared outcomes of ICH patients with and without COVID-19 infection admitted during the pandemic (from March 2020 to February 2021). Second, we compared the same outcomes between ICH patients admitted before (March 2019 to February 2020) and during (March 2020 and February 2021) the pandemic. Main outcomes were poor functional outcome (defined as a modified Rankin Scale of 4 to 6 [mRS] at discharge), mortality and discharge to skilled nursing facility (SNF) or hospice.ResultsThe first stage included 60,091 COVID-19-negative and 1,326 COVID-19-positive ICH patients. In multivariable analyses, ICH patients with versus without COVID-19 infection had 68% higher odds of poor outcome (OR 1.68, 95%CI 1.41-2.01), 51% higher odds of mortality (OR 1.51, CI 1.33-1.71) and 66% higher odds of being discharged to a SNF/hospice (OR 1.66, 95%CI 1.43-1.93). The second stage included 62,743 pre-pandemic and 64,681 intra-pandemic ICH cases. In multivariable analyses, ICH patients admitted during versus before the COVID-19 pandemic had a 10% higher odds of poor outcome (OR 1.10, 95%CI 1.07-1.14), 5% higher mortality (OR 1.05, 95%CI 1.02-1.08) and no significant difference in the risk of being discharged to SNF/hospice (OR 0.93, 95%CI 0.90-0.95).ConclusionsThe pathophysiology of the COVID-19 infection and changes in healthcare delivery during the pandemic played a role in worsening outcomes in this patient population. Further research is needed to identify these factors and understand their effect on the long-term outcome.

Background: Patients evaluated for coronary artery disease have a range of symptoms and underlying risk. The relationships between patient-described symptoms, clinician conclusions, and subsequent clinical management and outcomes remain incompletely described. Methods: In this secondary analysis, we examined the association between 4 types of presenting symptoms (substernal/left-sided chest pain, other chest/neck/arm pain, dyspnea, and other symptoms) and patient risk, noninvasive test results, clinical management, and outcomes for stable outpatients randomized in the PROMISE (Prospective Multicenter Imaging Study for Evaluation of Chest Pain) trial. Multivariable regression models were used to evaluate differences in noninvasive test result, all-cause death/myocardial infarction/unstable angina hospitalization and cardiovascular death/myocardial infarction by symptom type. Results: Among 9996 patients, most presented with chest pain (47.2% substernal, 29.2% other), followed by dyspnea (14.9%), and other symptoms (8.7%). Patients with dyspnea were older (median age 63 versus 60, P ≤0.02) with higher baseline risk (78.2% with atherosclerotic cardiovascular disease >7.5% versus 67.6%, P ≤0.02). Using patients with substernal chest pain as a reference, there was no difference in noninvasive test positivity across symptom groups (all P >0.05), but test-positive patients with dyspnea (adjusted odds ratio, 0.66 [95% CI, 0.51–0.85]) or other symptoms (adjusted odds ratio, 0.65 [95% CI, 0.47–0.90]) were less likely to be referred for cardiac catheterization. While symptom type alone was not associated with outcomes, symptom presentation with chest pain or dyspnea did modify the association between a positive noninvasive test and clinical outcome (interaction P =0.025 for both all-cause death/myocardial infarction/unstable angina hospitalization and cardiovascular death/MI). Conclusions: Among low-risk outpatients evaluated for coronary artery disease, typicality of symptoms was not closely associated with higher baseline risk but was related to differences in processes of care and the prognostic value of a positive test. Adverse events were not associated with clinician risk estimates or symptoms alone. These unexpected findings highlight the limitation of relying solely on symptom presentation or clinician risk estimation to evaluate patients for suspected coronary artery disease.

Background: Patients with ischemic stroke have worse outcome if there is concomitant coronavirus 2019 (COVID-19) infection. We hypothesize that patients with intracerebral hemorrhage (ICH) during the pandemic era had worse outcomes than ICH patients during the pre-pandemic period, and that concomitant COVID-19 in ICH patients is associated with worse outcome. Methods: We analyzed data from Get With The Guidelines® Stroke. We implemented a two-stage design: first, we compared outcomes for ICH patients pre-pandemic (admitted between March 2019 and February 2020) with outcomes for ICH patients admitted during the pandemic (from March 2020 to February 2021); second, we compared outcomes of ICH patients with and without COVID-19 infection admitted during the pandemic (from March 2020 to February 2021). We used multivariable logistic regression adjusted by age, sex, race/ethnicity, and clinical covariates for in-hospital mortality and poor functional outcome using the modified Rankin Scale (mRS) at discharge (mRS >= 4) and a for length of stay (LOS). Results: The first stage included 62,743 pre-pandemic and 64,681 intra-pandemic ICH cases 64,681. ICH patients during the pandemic had worse outcomes, including higher modified rankin scale (mRS) (OR 1.10, CI 1.06-1.14) and higher mortality (OR 1.04, CI 1.01-1.07). The second stage included 60,091 COVID-19-negative and 1,326 COVID-19-positive ICH patients. Patients with concomitant COVID-19 infection had worse outcomes, including higher LOS (RR 1.32, CI 1.25-1.39), high mRS (OR 1.68, CI 1.40-2.01), and increased mortality (OR 1.50, CI 1.33-1.71). (Table). Conclusion: When comparing pre- and intra-pandemic cases of ICH, critically ill stroke patients admitted during the pandemic had worse outcomes. When comparing COVID-19 positive and negative ICH cases that happened during the pandemic, those with the infection had worse clinical outcomes. COVID-19 infection is an independent risk factor for poor outcomes in ICH.

Introduction: Although the current guidelines recommend procoagulant reversal of elevated INR >= 2.0 (International Normalized Ratio) in patients with intracranial hemorrhage using warfarin, the benefit of procoagulant reversal is uncertain when patients have abnormal coagulation but are not fully anticoagulated. Hypothesis: For patients using warfarin (INR 1.5 to 1.9) who have intracranial hemorrhage the use of procoagulant reversal will improve functional outcome based upon dichotomized discharge mRS (modified Rankin scale) 0-3 vs 4-6. Methods: The Get With The Guidelines - Stroke registry was used to identify 239,681 patients with intracranial hemorrhage from hospitals using the comprehensive stroke center form between January 1, 2015 and January 4, 2022. Patients were excluded if they received thrombolytics, were using direct oral anticoagulants, if INR was not between 1.5 and 1.9, or if they were not using warfarin. To evaluate the association between procoagulant reversal and mRS at discharge, 1868 patients with non-missing mRS were analyzed for the primary outcome (mRS 0-3 vs. 4-6). Secondary outcomes that did not require mRS were analyzed among a possible 2569 patients. Propensity scores were estimated and overlap weighting was used to account for confounding. Logistic and negative binomial regression models were fit for binary and count variables, respectively. Results: There was an even distribution of patients into treatment and nontreatment (N=974 no reversal, N=894 reversal), and the groups were strikingly similar. Key outcomes are shown in the Table. Conclusions: Procoagulant reversal of warfarin for patients with acute intracranial hemorrhage and INR 1.5 - 1.9 was not associated with an improvement in functional outcome based upon mRS 0-3 vs 4-6. Patients that received a reversal agent had 25% lower odds of dying in the hospital or being discharged to hospice, but had a longer hospital stay and were less likely to be fully ambulatory at discharge.

Background: Basilar artery occlusion (BAO) is a devastating condition without definitive evidence to guide treatment. Whereas the association between faster treatment times with endovascular therapy (EVT) and better outcomes in anterior circulation is well established, whether this relationship exists for patients with BAO is not well delineated. Methods: We used individual-level patient data from the Get With The Guidelines–Stroke nationwide US registry prospectively collected from January 2015 to December 2019. We identified individuals with BAO treated with EVT within 24 hours of symptom onset. The primary outcomes examined were in-hospital mortality, discharge home, ambulatory at discharge, independent at discharge (modified Rankin Scale score 0 to 2), substantial reperfusion (modified Thrombolysis in Cerebral Infarction score 2b or 3), and symptomatic intracranial hemorrhage. Using logistic regression models, we evaluated the association between time from symptom onset to treatment with EVT and outcomes. Results: Among 3015 patients with BAO treated with EVT, the mean age was 65.9 years, 38.8% were women, and the median National Institutes of Health Stroke Scale score at presentation was 17 (interquartile range, 8–26). Median onset to EVT time was 406 minutes (interquartile range, 252–688). From 2015 to 2019, there was an overall increase in the median onset to EVT times (380–411 minutes; P =0.016) but no significant change in the proportion of patients treated within 6 hours of symptom onset (48.4%–44.0%; P =0.17). After risk adjustment for patient and hospital-level factors, there were significantly lower odds of in-hospital mortality (adjusted odds ratio [aOR], 0.55 [95% CI, 0.45–0.68]) and symptomatic intracranial hemorrhage (aOR, 0.52 [95% CI, 0.32–0.84]) and significantly higher odds of ambulation at discharge (aOR, 1.72 [95% CI, 1.37–2.16]), discharge home (aOR, 2.19 [95% CI, 1.73–2.77]), and independence at discharge (aOR, 2.21 [95% CI, 1.66–2.95]) when onset to EVT time was ≤6 hours compared with >6 hours. The fastest decay in good outcomes per hour occurred within 6 hours of symptom onset. Conclusions: Among patients receiving EVT for BAO, faster treatment from symptom onset was associated with improved outcomes. These findings support efforts to achieve rapid treatment with EVT for patients with BAO.

ObjectiveTo evaluate informal physician judgement versus pretest probability scores in estimating risk in patients with suspected coronary artery disease (CAD).MethodsWe included 4533 patients from the PROMISE (Prospective Multicenter Imaging Study for Evaluation of Chest Pain) trial. Physicians categorised a priori the pretest probability of obstructive CAD (≥70% or ≥50% left main); Diamond-Forrester (D-F) and European Society of Cardiology (ESC) pretest probability estimates were calculated. Agreement was calculated using the κ statistic; logistic regression evaluated estimates of pretest CAD probability and actual CAD (as determined by CT coronary angiography), and clinical outcomes were modelled using Cox proportional hazard models.ResultsPhysician estimates agreed poorly with D-F (κ 0.16; 95% CI 0.14 to 0.18) and ESC (κ 0.04; 95% CI 0.02 to 0.05). Actual obstructive CAD was significantly more prevalent in both the high-likelihood (OR 3.30; 95% CI 2.30 to 4.74) and the intermediate-likelihood (OR 1.43; 95% CI 1.16 to 1.76) physician-estimated groups versus the low-likelihood group; ESC similarly differentiated between the three groups (OR 9.07; 95% CI 2.87 to 28.70; and OR 3.87; 95% CI 1.22 to 12.28). However, using D-F, only the high-probability group differed (OR 2.49; 95% CI 1.74 to 3.54). Only physician estimates were associated with a higher incidence of adjusted death/myocardial infarction/unstable angina hospitalisation in the high-probability versus low-probability group (HR 2.68; 95% CI 1.52 to 4.74); neither pretest probability score provided prognostic information.ConclusionsCompared with D-F and ESC estimates, physician judgement more accurately identified obstructive CAD and worse patient outcomes. Integrating physician judgement may improve risk prediction for patients with stable chest pain.Trial registration numberNCT01174550.

Background: Alignment between clinician-reported New York Heart Association (NYHA) class compared and patient-reported outcomes among patients hospitalized for heart failure is unclear. Methods: ASCEND-HF (Acute Study of Clinical Effectiveness of Nesiritide in Decompensated Heart Failure) was a global randomized trial comparing nesiritide versus placebo among patients hospitalized for heart failure, irrespective of ejection fraction. Among patients with complete baseline data for NYHA class and the patient-reported EuroQOL-5 dimensions ([EQ-5D], both utility index and visual analog scale), levels of each scale were mapped across 4 prespecified categories “best” to “worst.” Minor and moderate-severe discordance were defined as NYHA class and EQ-5D differing by 1 level and ≥2 levels, respectively. Multivariable models assessed factors independently associated with moderate-severe discordance, and associations between discordance and clinical outcomes. Results: Among 5741 patients, concordance, minor discordance, and moderate-severe discordance between NYHA class and EQ-5D utility index occurred in 22%, 40%, and 38% of patients, respectively. For NYHA class and EQ-5D visual analog scale, this categorization occurred in 29%, 48%, and 23%. Discordance was more often due to disproportionately higher EQ-5D score (78% of discordance cases with utility index, and 70% with visual analog scale). NYHA class IV, higher EQ-5D scores, race, and geographic region were among patient factors independently associated with moderate-severe discordance. Magnitude of discordance was not associated with clinical outcomes; however, EQ-5D utility index disproportionately worse than NYHA class was associated with increased 180-day mortality (adjusted hazard ratio 1.27 [95% CI, 1.01–1.60]; P =0.04). Conclusions: In a global trial cohort of patients hospitalized for heart failure, the majority of patients exhibited discordance between clinician-reported NYHA class and patient-reported health status. Multiple patient factors were independently associated with moderate-severe discordance, and patients who perceived their health status as worse than the clinician’s perception had higher mortality.

Non-coronary vascular disease (NCVD) is associated with adverse cardiovascular events. Little is known about physician risk assessment, prevalence of coronary artery disease (CAD), cardiac catheterization, and the performance of the atherosclerotic cardiovascular disease (ASCVD) risk score in patients with NCVD.Retrospective analysis of outpatients with angina and no known CAD from the PROMISE trial. NCVD included carotid artery stenosis ≥50%, or history of stroke or peripheral artery disease. Multivariable models of physician estimates of the probability of obstructive CAD, prevalence of non-obstructive and obstructive CAD, referral to cardiac catheterization, and all-cause death/myocardial infarction/unstable angina were performed.Among 10,001 patients in the PROMISE trial, 379 (3.8%) patients had NCVD. Only 8.5% of participants with NCVD were categorized as high-risk for obstructive CAD by physicians, though 15.5% (25/161) had obstructive CAD in those randomized to coronary computed tomography (CTA). NCVD was independently associated with non-obstructive (aOR = 1.58; 95% CI 1.18-2.61; P = .006) but not obstructive CAD by CTA. Adjusted referral to cardiac catheterization was similar with and without NCVD (aOR 1.04; 95% CI 0.88-1.94, P = .19). NCVD was associated with an increased risk of all-cause death/MI/UA (aOR 2.03; 95% CI 1.37-3.01, P.001). There was no interaction between NCVD status and ASCVD risk score.Among patients with NCVD and angina, NCVD had increased adjusted risks of CAD and adverse outcomes which were not well described by ASCVD risk score and were underrecognized by physicians. Increased awareness and better risk stratification tools for patients with NCVD may be necessary to recognize the associated CV risk and optimize diagnostic testing and therapies.

BACKGROUND: Heuristic biases are increasingly recognized, and potentially modifiable, contributors to patient care and outcomes. Left digit bias is a cognitive bias where continuous variables are categorized by their left-most digit. The impact of this heuristic bias applied to patient age on quality of care in heart failure has not been explored. METHODS: We examined participants admitted from 2005 to 2021 in the Get With The Guidelines-Heart Failure registry. To create 2 naturally randomized groups, isolating the effect of left digit bias, we dichotomized patients into those discharged within 60 days prior to their 80th birthday (N=4238) and those discharged within 60 days after their 80th birthday (N=4329). We performed multivariable logistic regression to assess the association between discharge date relative to 80th birthday and several in-hospital quality metrics and in-hospital outcomes. Among Medicare participants (N=2759), we performed adjusted Cox regression to analyze the relationship between discharge date and risk of 1-year mortality or readmission. RESULTS: 50.4% were female, 73% were non-Hispanic White, and 42.9% had an ejection fraction ≤40%. Discharge date relative to 80th birthday was not associated with numerous in-hospital quality metrics or in-hospital outcomes on unadjusted or adjusted logistic regression. Among Medicare beneficiaries, there was no association between discharge date and risk of mortality or readmission at 1-year postdischarge (hazard ratio, 1.03 [95% CI, 0.95–1.12]; P =0.52). CONCLUSIONS: In a large registry of patients hospitalized for heart failure, we did not detect a left digit bias‚ with respect to age at discharge, which resulted in differential quality of care or outcomes.

Introduction: Atrial fibrillation or flutter (AF) and heart failure (HF) frequently coexist, yet few studies have examined longitudinal trends or post-discharge outcomes in this disease intersection. Methods: We evaluated 429,464 participants hospitalized for HF and left ventricular ejection fraction >40% across 644 sites in the Get With The Guidelines-Heart Failure (GWTG-HF) registry from January 2014 to December 2020. We compared clinical profiles among those with and without AF (defined by medical history or occurring at presentation or during hospitalization). We additionally examined 12-month post-discharge death and all-cause/cause-specific readmissions among 79,895 participants ≥65 years discharged alive with linked Centers for Medicare & Medicaid Services inpatient files and Parts A, B, and D Fee-for-Service eligibility. Results: Prevalence of AF increased from 48.5% in Q1 2014 to 52.1% in Q4 2020 among the 76,886 patients with HF with mildly reduced ejection fraction (HFmrEF; 41-49%) and increased from 49.7% to 50.1% among the 352,578 patients with HF with preserved ejection fraction (HFpEF; ≥50%); both P-trendFigure ). Conclusions: Prevalence of AF is rising among patients hospitalized with HFmrEF and HFpEF. AF is independently associated with increased post-discharge risks of death and a broad range of clinical events requiring rehospitalization.

Aims Associations between growth differentiation factor‐15 (GDF‐15), cardiovascular outcomes, and exercise capacity among patients with a recent hospitalization for heart failure (HHF) and heart failure with reduced ejection fraction (HFrEF) are unknown. We utilized data from the ‘Functional Impact of GLP‐1 for Heart Failure Treatment’ (FIGHT) study to address these knowledge gaps. Methods and results FIGHT was a randomized clinical trial testing the effect of liraglutide (vs. placebo) among 300 participants with HFrEF and a recent HHF. Multivariable regression models evaluated associations between baseline GDF‐15 and change in GDF‐15 (per 1000 pg/mL increase from baseline to 30 days) with clinical outcomes (at 180 days) and declines in exercise capacity (6 min walk distance ≥ 45 m). At baseline (n = 249), median GDF‐15 value was 3221 pg/mL (interquartile range 1938–5511 pg/mL). Participants in the highest tertile of baseline GDF‐15 were more likely to be male and have more co‐morbidities. After adjustment, an increase in GDF‐15 over 30 days was associated with higher risk of death or HHF [hazard ratio 1.35, 95% confidence interval (CI) 1.11–1.64]. In addition, higher baseline GDF‐15 (per 1000 pg/mL until 6000 pg/mL) and an increase in GDF‐15 over 30 days were associated with declining 6 min walk distance (odds ratio 1.26, 95% CI 1.02–1.55 and odds ratio 1.37, 95% CI 1.12–1.69, respectively). GDF‐15 levels remained stable among participants randomized to liraglutide. Conclusions An increase in GDF‐15 over 30 days among patients in HFrEF was independently associated with an increased risk of cardiovascular events and declining exercise capacity. These results support the value of longitudinal GDF‐15 trajectory in informing risk of heart failure disease progression.

Background and Purpose: Studies suggest an increased risk of adverse outcomes among patients with acute ischemic stroke (AIS) and coronavirus disease 2019 (COVID-19). Methods: Using Get With The Guidelines–Stroke, we identified 41 971 patients (AIS/COVID-19: 1143; AIS/no COVID-19: 40 828) with AIS hospitalized between February 4, 2020 and June 29, 2020, from 458 Get With The Guidelines–Stroke hospitals with at least one COVID-19 case and evaluated clinical characteristics, treatment patterns, and outcomes. Results: Compared with patients with AIS/no COVID-19, those with AIS/COVID-19 were younger, more likely to be non-Hispanic Black, Hispanic, or Asian, more likely to present with higher National Institutes of Health Stroke Scale scores, and had greater proportions of large vessel occlusions. Rates of thrombolysis and thrombectomy were similar between the groups. Door to computed tomography (median 55 [18–207] versus 35 [14–99] minutes, P P P =0.002) times were longer in the AIS/COVID-19 cohort. In adjusted models, patients with AIS/COVID-19 had decreased odds of discharge with modified Rankin Scale score of ≤2 (odds ratio, 0.65 [95% CI, 0.52–0.81], P P ConclusionS: This analysis demonstrates younger age, greater stroke severity, longer times to evaluation and treatment, and worse morbidity and mortality in patients with AIS/COVID-19 compared with those with AIS/no COVID-19.

Objective Musculoskeletal pain conditions are a leading cause of pain and disability internationally and a common reason to seek health care. Accurate prediction of recurrence of health care seeking due to musculoskeletal conditions could allow for better tailoring of treatment. The aim of this project was to characterize patterns of recurrent physical therapy seeking for musculoskeletal pain conditions and to develop a preliminary prediction model to identify those at increased risk of recurrent care seeking. Design Retrospective cohort. Setting Ambulatory care. Subjects Patients (n = 578,461) seeking outpatient physical therapy (United States). Methods Potential predictor variables were extracted from the electronic medical record, and patients were placed into three different recurrent care categories. Logistic regression models were used to identify individual predictors of recurrent care seeking, and the least absolute shrinkage and selection operator (LASSO) was used to develop multivariate prediction models. Results The accuracy of models for different definitions of recurrent care ranged from 0.59 to 0.64 (c-statistic), and individual predictors were identified from multivariate models. Predictors of increased risk of recurrent care included receiving workers’ compensation and Medicare insurance, having comorbid arthritis, being postoperative at the time of the first episode, age range of 44–64 years, and reporting night sweats or night pain. Predictors of decreased risk of recurrent care included lumbar pain, chronic injury, neck pain, pregnancy, age range of 25–44 years, and smoking. Conclusion This analysis identified a preliminary predictive model for recurrence of care seeking of physical therapy, but model accuracy needs to improve to better guide clinical decision-making.

International audience; Background: Prior analyses suggest an association between formula-based plasma volume (PV) estimates and outcomes in heart failure (HF). We assessed the association between estimated PV status by the Duarte-ePV and Kaplan Hakim (KH-ePVS) formulas, and in-hospital and postdischarge clinical outcomes, in the ASCEND-HF trial.Methods and results: The KH-ePVS and Duarte-ePV were calculated on admission. We assessed associations with in-hospital worsening HF, 30-day composite cardiovascular mortality or HF rehospitalization and 180-day all-cause mortality. There were 6373 (89.2%), and 6354 (89.0%) patients who had necessary characteristics to calculate KH-ePVS and Duarte-ePV, respectively. There was no association between PV by either formula with in-hospital worsening HF. KH-ePVS showed a weak correlation with N-terminal prohormone BNP, and with measures of decongestion such as body weight change and urine output (r < 0.3 for all). Duarte-ePV was trending toward an association with worse 30-day (adjusted odds ratio 1.07, 95% confidence interval [CI] 1.00-1.15, P = .058), but not 180-day outcomes (adjusted hazard ratio 1.03, 95% CI 0.97-1.09, P = .289). A continuous KH-ePVS of >0 (per 10-unit increase) was associated with improved 30-day outcomes (adjusted odds ratio 0.75, 95% CI 0.62-0.91, P = .004). The continuous KH-ePVS was not associated with 180-day outcomes (adjusted hazard ratio 1.05, 95% CI 0.98-1.12, P = .139).Conclusions: Baseline PV estimates had a weak association with in-hospital measures of decongestion. The Duarte-ePV trended toward an association with early clinical outcomes in decompensated HF, and may improve risk stratification in HF.

Redox balance and methylation are crucial to homeostasis and are linked by the methionine-homocysteine cycle. We examined whether differences in methylation potential, measured as plasma levels of S-adenosyl methionine (SAM) and S-adenosyl homocysteine (SAH), occur at baseline and during anti-oxidant therapy with the xanthine oxidase inhibitor allopurinol in patients with heart failure with reduced ejection fraction. We analyzed plasma samples collected at baseline and 24 weeks in the Xanthine Oxidase Inhibition for Hyperuricemic Heart Failure Patients (EXACT-HF) study, which randomized patients with heart failure with reduced ejection fraction to allopurinol or placebo. Associations between plasma levels of SAM, SAH, SAM/SAH ratio, and outcomes, including laboratory markers and clinical events, were assessed. Despite randomization, median SAM levels were significantly lower at baseline in the allopurinol group. SAH levels at 24 weeks, and change in SAM from baseline to week 24, were significantly higher in the group of patients randomized to allopurinol compared to the placebo group. A significant correlation was observed between change in SAH levels and change in plasma uric acid (baseline to 24-week changes) in the allopurinol group. There were no significant associations between levels of SAM, SAH, and SAM/SAH ratio and clinical outcomes. Our results demonstrate significant biological variability in SAM and SAH levels at baseline and during treatment with an anti-oxidant and suggest a potential mechanism for the lack of efficacy observed in trials of anti-oxidant therapy. These data also highlight the need to explore personalized therapy for heart failure.

We examined the relationship between pain severity and outcomes in patients with heart failure with reduced ejection fraction (HFrEF) in the HF-ACTION randomized controlled trial. Trends of health-related quality of life (HRQoL) measures grouped by patients' self-reported baseline bodily pain severity were compared using correlation tests, and the association between pain severity and clinical outcomes (including a primary composite endpoint of all-cause mortality and all-cause hospitalization) was assessed using multivariable adjusted analyses. Of the 2310 patients, 22.9% reported no pain, 45.8% very mild/mild, 24.9% moderate, and 6.4% severe/very severe. Greater pain severity was associated with worse HRQoL measures (EuroQoL-5D-3L and Kansas City Cardiomyopathy Questionnaire; both p < 0.0001). Compared to those reporting no pain, patients reporting severe/very severe pain had greater risk for the primary endpoint (adjusted hazard ratio 1.42, 95% confidence interval 1.11-1.83, p = 0.01). In patients with HFrEF, greater pain severity was associated with worse HRQoL and clinical outcomes. Trial Registration: NCT00047437.

Objectives We aimed to evaluate the association between levosimendan treatment and acute kidney injury (AKI) as well as assess the clinical sequelae of AKI in cardiac surgery patients with depressed left ventricular function (ejection fraction Methods Patients in the LEVO-CTS trial undergoing on-pump coronary artery bypass grafting (CABG), valve, or CABG/valve surgery were stratified by occurrence and severity of postoperative AKI using the AKIN classification. The association between levosimendan infusion and AKI was modeled using multivariable regression. Results Among 854 LEVO-CTS patients, 231 (27.0%) experienced postoperative AKI, including 182 (21.3%) with stage 1, 35 (4.1%) with stage 2, and 14 (1.6%) with stage 3 AKI. The rate of AKI was similar between patients receiving levosimendan or placebo. The odds of 30-day mortality significantly increased by AKI stage compared to those without AKI (stage 1: adjusted odds ratio [aOR] 2.0, 95% confidence interval [CI] 0.8-4.9; stage 2: aOR 9.1, 95% CI 3.2-25.7; stage 3: aOR 12.4, 95% CI 3.0-50.4). No association was observed between levosimendan, AKI stage, and odds of 30-day mortality (interaction P = .69). Factors independently associated with AKI included increasing age, body mass index, diabetes, and increasing baseline systolic blood pressure. Increasing baseline eGFR and aldosterone antagonist use were associated with a lower risk of AKI. Conclusions Postoperative AKI is common among high-risk patients undergoing cardiac surgery and associated with significantly increased risk of 30-day death or dialysis. Levosimendan was not associated with the risk of AKI.

Purpose We aimed to 1) describe characteristics of patients with heart failure with preserved ejection fraction (HFpEF) enrolled in RELAX stratified by normal or elevated baseline serum uric acid (sUA) level; 2) evaluate the association between sUA level and surrogate clinical measures; and 3) assess associations between changes in sUA level over time and changes in surrogate clinical measures. Methods We analyzed 212 patients with HFpEF and normal or elevated (>6 mg/dL) baseline sUA measurements from the RELAX trial. Variables examined included clinical characteristics, cardiopulmonary exercise testing, 6-minute walk testing, quality of life, echocardiography, and serum biomarker testing. Baseline characteristics between groups were compared and scatter plots with quadratic regression lines and linear regression modeling were used to assess the relationship between baseline sUA and clinical measures. Kaplan–Meier curves were used to describe composite death or cardiovascular/renal hospitalization. Results The prevalence of elevated baseline sUA was 68.9%. Patients with elevated sUA had more baseline comorbidities and poorer functional status on cardiopulmonary exercise testing than those without. After adjustment, significant associations between baseline sUA levels and cystatin C, N-terminal pro B-type natriuretic peptide, high-sensitivity troponin I, and high-sensitivity C-reactive protein were identified. Higher baseline sUA was also associated with worsening peak VO2, 6-minute walk testing, and left ventricular mass. No significant association was found between baseline sUA levels and the composite of death or cardiovascular/renal hospitalization at 24 weeks. Conclusion sUA is an important marker of comorbidities and functional status in patients with HFpEF. Clinical trials of sUA-lowering therapies in patients with HFpEF are promising.

To develop and validate a model to predict obstetric anal sphincter injuries (OASIS) using only information available at the time of admission for labour.A clinical predictive model using a retrospective cohort.A US health system containing one community and one tertiary hospital.A total of 22 873 pregnancy episodes with in-hospital delivery at or beyond 21 weeks of gestation.Thirty antepartum risk factors were identified as candidate variables, and a prediction model was built using logistic regression predicting OASIS versus no OASIS. Models were fit using the overall study population and separately using hospital-specific cohorts. Bootstrapping was used for internal validation and external cross-validation was performed between the two hospital cohorts.Model performance was estimated using the bias-corrected concordance index (c-index), calibration plots and decision curves.Fifteen risk factors were retained in the final model. Decreasing parity, previous caesarean birth and cardiovascular disease increased risk of OASIS, whereas tobacco use and black race decreased risk. The final model from the total study population had good discrimination (c-index 0.77, 95% confidence interval [CI] 0.75-0.78) and was able to accurately predict risks between 0 and 35%, where average risk for OASIS was 3%. The site-specific model fit using patients only from the tertiary hospital had c-stat 0.74 (95% CI 0.72-0.77) on community hospital patients, and the community hospital model was 0.77 (95%CI 0.76-0.80) on the tertiary hospital patients.OASIS can be accurately predicted based on variables known at the time of admission for labour. These predictions could be useful for selectively implementing OASIS prevention strategies.

Clinical guidelines recommend titration of angiotensin converting enzyme inhibitors (ACEi) and beta-blockers among patients with heart failure with reduced ejection fraction (HFrEF) to maximally tolerated doses. Patient characteristics associated with dose titration and clinical outcomes subsequent to dose titration remain poorly characterized.Among 1999 ambulatory patients with chronic HFrEF in the HF-ACTION trial, use and dosing of ACEi and evidence-based beta-blockers were examined at baseline and 6-month follow-up. Multivariable logistic regression models were used to assess factors associated with dose escalation (medication initation or dosing increase) or dose de-escalation (medication discontinuation or dosing decrease). Cox proportional hazard regression models were used to examine associations between dose trajectory group (stable target, stable sub-target, dose escalation, and dose de-escalation) and subsequent mortality and hospitalization outcomes.For both ACEi and beta-blockers, hospitalization for heart failure in the 6 months prior to enrollment (odds ratio [OR] 2.32 [95% confidence interval 1.58-3.42]) for ACEi; 1.42 [1.05-1.9] for beta-blockers) and higher systolic blood pressure (OR 1.01 [1.00-1.03] per 1 mmHg increase for ACEi; 1.01 [1.00-1.02] for beta-blockers) were associated with dose escalation. Hospitalization 6 months prior to enrollment for any cause (including HF or non-HF causes) was associated with dose de-escalation (OR 1.60 [1.14-2.25] for ACEi; 1.67 [1.20-2.33] for beta-blockers). After adjustment for patient characteristics, compared with stable target dosing, dose de-escalation of either medication was associated with greater all-cause mortality (adjusted hazard ratio [aHR] 1.64 [1.11-2.42] for ACEi; 1.62 [1.04-2.53] for beta-blockers). Compared with stable target dosing, both dose de-escalation (aHR 1.98 [1.36-2.87]) and stable sub-target dosing (aHR 1.49 [1.18-1.87]) of beta-blockers were associated with greater cardiovascular mortality or hospitalization for heart failure.Among outpatients with chronic HFrEF, patient characteristics including recent hospitalization status and blood pressure were associated with odds of subsequent escalation and de-escalation of ACEi and beta-blocker therapy. Compared with patients receiving guildeline-recommended target doses, dose de-escalation of either medication and sub-target dosing of beta-blockers were associated with greater morbidity and mortality over long-term follow-up.

BACKGROUND: While left atrial (LA) mechanical dysfunction in heart failure with preserved ejection fraction (HFpEF) is associated with poor clinical outcomes, the influence of LA myopathy on temporal changes in cardiovascular biomarkers is unclear. METHODS AND RESULTS: We evaluated biomarker correlates of LA myopathy, as defined by reduced LA strain, and the associations of LA strain with longitudinal changes in biomarkers among participants in the Phosphodiesterase-5 Inhibition to Improve Clinical Status and Exercise Capacity in Heart Failure with Preserved Ejection Fraction (RELAX) trial. LA speckle-tracking was performed on baseline echocardiograms of RELAX participants to measure LA reservoir and LA contractile strain. Of the 216 RELAX participants, 169 (78%) had measurable LA strain and biomarker data. Participants with LA reservoir strain below median (13.5%, interquartile range: 10–22.5%) were older, more likely to have atrial fibrillation, and had higher jugular venous pressure (P

Introduction: Use of oral anticoagulation (OAC) in patients with atrial fibrillation (AF) and cancer is challenging due to increased thrombotic and bleeding risks, and data on prescription patterns are lacking. Hypothesis: Underutilization of OAC among patients with AF and cancer is associated with cancer specific factors. Methods: This study examined OAC use and factors associated with discontinuation of OAC among Medicare patients with AF and a new diagnosis of cancer from 2011-2016. We described OAC use patterns prior to and after a diagnosis of cancer. Logistic regression was used to evaluate clinical variables associated with discontinuation of OAC at time of cancer diagnosis and cox proportional hazards model was used to evaluate variables associated with discontinuation after diagnosis. Results: Among 44,769 patients with established AF and newly diagnosed cancer, 30.2% (n=13,508) were taking OAC at the time of cancer diagnosis. A total of 15,228 patients (34%) had an OAC prescription fill after index cancer diagnosis. Warfarin was the most commonly used OAC, but direct oral anticoagulant use increased over the study period. A total of 29.5% of patients had their OAC discontinued at the time of cancer diagnosis. Patients with gastric (OR 2.75, CI 2.12-3.57), pancreatic (OR 2.71, CI 2.15-3.41), and colorectal (OR 1.97, CI 1.70-2.28) cancer were most likely to have their OAC discontinued at diagnosis (Figure). Bleeding (HR1.37, CI 1.28-1.48) and chemotherapy (HR 1.38, CI 1.06-1.80) were associated with subsequent discontinuation in those who remained on OAC after diagnosis. Conclusions: Nearly 2 in 3 patients with established AF were not treated with OAC after cancer diagnosis despite an elevated stroke risk. Significant heterogeneity in OAC use exists depending on cancer type, baseline comorbidities, and chemotherapy use. Studies are needed to characterize the thrombotic and bleeding risks in this population to establish management guidelines.

Background and Purpose: Patients with prestroke mobility impairment (PSMI) were excluded from endovascular clinical trials. There are limited data regarding safety and outcomes of endovascular thrombectomy in this population. We used a large, national data set (Get With The Guidelines–Stroke) to evaluate the safety and outcomes of endovascular thrombectomy in patients with PSMI. Methods: We included patients who underwent endovascular thrombectomy in the Get With The Guidelines–Stroke registry between 2015 and 2019. PSMI was defined as the inability to ambulate independently. Generalized estimating equations for logistic regression models were used to evaluate the association between PSMI and outcomes. Results: Of 56 762 patients treated with endovascular thrombectomy, 2919 (5.14%) had PSMI. PSMI was not associated with symptomatic intracranial hemorrhage (6.0% versus 5.4%; P =0.979). In-hospital death or discharge to hospice occurred in 32.3% of patients with PSMI versus 17.5% without PSMI (adjusted odds ratio, 1.45 [1.32–1.58]). Conclusions: While procedural adverse outcomes were no higher in patients with PSMI, further study is necessary to determine clinical benefit in this population.

Background: Multiple states have not expanded Medicaid under the Affordable Care Act, resulting in higher uninsured rates in states with high stroke burdens. This study aimed to evaluate the association of Medicaid expansion with changes in health insurance coverage, severity of presentation, access to care, and outcomes among patients with acute ischemic stroke. Methods: A retrospective, difference-in-differences analysis of Get With The Guidelines–Stroke registry data. The study population comprised first-time ischemic stroke admissions from 2012 to 2018 for patients aged 19 to 64 in 45 states (27 that expanded Medicaid and 18 that did not). A probable low-income cohort was defined based on having Medicaid, no insurance/self-pay, or undocumented insurance. Outcomes analyzed were indicators of health insurance status, stroke severity, use of emergency services, time to acute care, in-hospital mortality, receipt of rehabilitation, discharge disposition, and level of disability. Results: In the starting population (N=342 765), Medicaid-covered stroke admissions rose from 12.2% to 18.1% in expansion states and from 10.0% to only 10.6% in nonexpansion states, while uninsured admissions declined from 15.0% to 6.7% in expansion states and from 24.0% to 19.2% in nonexpansion states. In the low-income cohort (N=95 086; 28% of starting population), Medicaid expansion was associated with increased odds of discharge to a skilled nursing facility (adjusted odds ratio, 1.33 [95% CI, 1.12–1.59]) and transfer to any rehabilitation facility among those eligible (adjusted odds ratio, 1.24 [95% CI, 1.08–1.41]) and lower odds of discharge home (adjusted odds ratio, 0.89 [95% CI, 0.80–0.98]). Expansion was not associated with any other outcomes. Conclusions: Medicaid expansion is associated with fewer uninsured hospitalizations for acute ischemic stroke and increased rehabilitation at skilled nursing facilities. More targeted interventions may be needed to improve other stroke outcomes in the low-income US population. Future research should evaluate the impact of health care reform on primary stroke prevention.

Supplemental Digital Content is available in the text., Background and Purpose: The coronavirus disease 2019 (COVID-19) pandemic has created challenges in the delivery of acute stroke care. In this study, we analyze the characteristics, evaluation, treatment, and in-hospital outcomes of patients presenting with acute ischemic stroke (AIS) pre-COVID-19 and during COVID-19. Methods: Get With The Guidelines-Stroke is a national registry of adults with stroke in the United States. Using this registry, we identified patients with a diagnosis of AIS before (n=39 113; November 1, 2019–February 3, 2020) and after (n=41 971; February 4, 2020–June 29, 2020) the first reported case of COVID-19 in the registry. Characteristics, treatment patterns, quality metrics, and in-hospital outcomes were compared between the 2 groups. Results: Stroke presentations decreased by an average of 15.3% per week in the during COVID-19 time period when compared with similar months in 2019. Compared with patients with AIS in the pre-COVID-19 era, patients in the COVID-19 time period had similar rates of intravenous alteplase and endovascular therapy, and similar door to computed tomography, door to needle, and door to endovascular therapy times. In adjusted models, inpatient mortality was similar between those presenting with AIS pre-COVID-19 and during COVID-19 (4.8% versus 5.2%; odds ratio, 1.05 [95% CI, 0.97–1.13]). Conclusions: Among hospitals participating in Get With The Guidelines-Stroke, patients presenting with AIS during COVID-19 received, with few exceptions, similar quality care and experienced similar risk-adjusted outcomes when compared with patients with AIS presenting pre-COVID-19. These findings demonstrate that stroke care in the United States remains robust during the COVID-19 pandemic.

BACKGROUND: Guidelines for evaluating patients with suspected coronary artery disease (CAD) recommend pretest probability (PTP) estimation but provide no clear recommendations regarding diagnostic testing in patients with >5% to 15% risk of obstructive CAD. The diagnostic and prognostic value of PROMISE (Prospective Multicenter Imaging Study for Evaluation of Chest Pain) minimal risk score (PMRS) calculation in this patient group is unknown.OBJECTIVES: This work aims to improve the evaluation of stable patients with suspected CAD by using the PMRS, which identifies patients at minimal risk of CAD and events in patients with >5% to 15% PTP of obstructive CAD.METHODS: Greater than 5% to 15% PTP patients from 2 large clinical trials were used for subcohort derivation: PROMISE (N = 10,003) and Dan-NICAD (Danish study of Non-Invasive Testing in Coronary Artery Disease) (N = 3,252). First, the PMRS cutoff associated with a prevalence of obstructive CAD ≤5% was determined in the >5% to 15% PTP PROMISE core lab computed tomographic angiography patients (discovery cohort: n = 2,191). This cutoff was validated for obstructive CAD in >5% to 15% PTP Dan-NICAD patients (CAD validation cohort: n = 1,386) and for prognostic impact on death and myocardial infarction in >5% to 15% PTP PROMISE non-core lab computed tomographic angiography patients (prognosis validation cohort: n = 2,753).RESULTS: In the discovery cohort, a CAD prevalence of ≤5% was found at a PMRS of ≥34%. In the CAD validation cohort, this cutoff down-classified 442 (31.9%) of >5% to 15% PTP patients into the low PTP group (CAD ≤5%); the prevalence of obstructive CAD in down-classified patients was 3.2% compared to 7.1% in non-down-classified patients. A PMRS ≥34% was nonsignificantly associated with a lower risk of myocardial infarction and death in the prognosis validation cohort (HR: 0.58 [95% CI: 0.29-1.18]; P = 0.13).CONCLUSIONS: For evaluating patients with suspected CAD, a combined use of traditional PTP and the PMRS correctly down-classified one-third of >5% to 15% PTP patients into a group with very low prevalence of obstructive CAD and adverse events. The proposed strategy may improve risk stratification and help reduce unneeded diagnostic testing.

Worsening heart failure (HF) often requires hospitalization but in some cases may be managed in the outpatient or emergency department (ED) settings. The predictors and clinical significance of ED visits without admission vs hospitalization are unclear.The ASCEND-HF trial included 2661 US patients hospitalized for HF with reduced or preserved ejection fraction. Clinical characteristics were compared between patients with a subsequent all-cause ED visit (with ED discharge) within 30 days vs all-cause readmission within 30 days. Factors associated with each type of care were assessed in multivariable models. Multivariable models landmarked at 30 days evaluated associations between each type of care and subsequent 150-day mortality.Through 30-day follow-up, 193 patients (7%) had ED discharge, 459 (17%) had readmission, and 2009 (76%) had neither urgent visit. Patients with ED discharge vs readmission were similar with respect to age, sex, systolic blood pressure, ejection fraction, and coronary artery disease, whereas ED discharge patients had a modestly lower creatinine (P.01). Among patients with either event within 30 days, a higher creatinine and prior HF hospitalization were associated with a higher likelihood of readmission, as compared with ED discharge (P.02). Landmarked at 30 days, rates of death during the subsequent 150 days were 21.0% for patients who were readmitted and 11.4% for patients discharged from the ED. Compared with patients who were readmitted, ED discharge was independently associated with lower 150-day mortality (adjusted hazard ratio 0.58, 95% confidence interval 0.36-0.92, P = .02).In this cohort of US patients hospitalized for HF, worse renal function and prior HF hospitalization were associated with a higher likelihood of early postdischarge readmission, as compared with ED discharge. Although subsequent mortality was high after discharge from the ED, this risk of mortality was significantly lower than patients who were readmitted to the hospital.

ObjectivesThis research evaluates whether environmental exposures (pesticides and smoke) influence respiratory and allergic outcomes in women living in a tropical, agricultural environment.MethodsWe used data from 266 mothers from the Infants’ Environmental Health cohort study in Costa Rica. We evaluated environmental exposures in women by measuring seven pesticide and two polycyclic aromatic hydrocarbons metabolites in urine samples. We defined ‘high exposure’ as having a metabolite value in the top 75th percentile. We collected survey data on respiratory and allergic outcomes in mothers as well as on pesticides and other environmental exposures. Using logistic regression models adjusted for obesity, we assessed the associations of pesticide exposure with multiple outcomes (wheeze, doctor-diagnosed asthma, high (≥2) asthma score based on symptoms, rhinitis, eczema and itchy rash).ResultsCurrent pesticide use in the home was positively associated with diagnosed asthma (OR=1.99 (95% CI=1.05 to 3.87)). High urinary levels of 5-hydroxythiabendazole (thiabendazole metabolite) and living in a neighbourhood with frequent smoke from waste burning were associated with a high asthma score (OR=1.84 (95%CI=1.05 to 3.25) and OR=2.31 (95%CI=1.11 to 5.16), respectively). Women who worked in agriculture had a significantly lower prevalence of rhinitis (0.19 (0.01 to 0.93)), but were more likely to report eczema (OR=2.54 (95%CI=1.33 to 4.89)) and an itchy rash (OR=3.17 (95%CI=1.24 to 7.73)).ConclusionsWhile limited by sample size, these findings suggest that environmental exposure to both pesticides and smoke may impact respiratory and skin-related allergic outcomes in women.

Stress echocardiography (SE) assesses for flow-limiting coronary artery disease (CAD) and requires expertise to interpret. Clinical trials use core laboratories to ensure that interpretations are accurate and reproducible. We determined agreement between site and core laboratory SE interpretations

e18674 Background: Unanticipated healthcare resource utilization, in the form of either emergency department utilization (EDUs) or hospital admission (HA), is an indicator of lower quality of cancer care. The objective of this study was to develop a comprehensive predictive model for emergency department utilization and hospital admission (HA) for patients with solid tumors who received chemotherapy within 30 days. Methods: We abstracted electronic health data on oncology encounters from all patients receiving systemic therapy chemotherapy for solid tumors from March 01, 2015 to August 21, 2020. Patients included in the cohort met the following criteria:1) Ages > = 18 years old 2) Diagnosed with any solid tumor (3) Had any oncology treatment plan related to their solid tumor diagnosis; 4) Received at least one chemotherapy during March 01, 2015 through August 21, 2020. We defined a primary composite outcome of emergency visit or unanticipated hospitalization within 30 days after the encounter. Patient information was abstracted. We developed a predictive model for the primary outcome using LASSO logistic regression modeling. To evaluate the model, we calculated the Area Under the Receiver Operator Characteristic (AUROC) and the calibration slope. Results: 12,917 unique patients with 134,641 encounters were included. Of these, 9100 (6.7%) of encounters were ED visits or hospitalizations. 714 patients (5.5%) had at least one ED visit or hospitalization within 30 days of treatment; patients at highest risk for this outcome included those with pancreatic cancer, lung cancer and ovarian/endometrial cancer (9.1%, 7.4% and 6.8% respectively). 38 variables were identified as contributing to the LASSO model. The top predictors, in order of importance, were fever, hypernatremia, hypotension and low albumin. The model’s AUC was 0.83, indicating good model sensitivity to outcome. Conclusions: Approximately 7% of healthcare encounters in patients undergoing treatment for solid malignancies were ED visits or hospitalizations. Identifying patients at highest risk for this outcome may prevent unnecessary resource utilization and optimize patient care during cancer treatment. The model developed in this study demonstrated good sensitivity and could be implemented in clinical practice to allow for preventive outpatient interventions. Work is ongoing to integrate this model into clinical care at our institution.[Table: see text]

Background Few contemporary data exist evaluating care patterns and outcomes in heart failure (HF) across the spectrum of kidney function. Objectives This study sought to characterize differences in quality of care and outcomes in patients hospitalized for HF by degree of kidney dysfunction. Methods Guideline-directed medical therapies were evaluated among patients hospitalized with HF at 418 sites in the GWTG-HF (Get With The Guidelines–Heart Failure) registry from 2014 to 2019 by discharge CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration)-derived estimated glomerular filtration rate (eGFR). We additionally evaluated the risk-adjusted association of admission eGFR with in-hospital mortality. Results Among 365,494 hospitalizations (age 72 ± 15 years, left ventricular ejection fraction [EF]: 43 ± 17%), median discharge eGFR was 51 ml/min/1.73 m2 (interquartile range: 34 to 72 ml/min/1.73 m2), 234,332 (64%) had eGFR Conclusions Despite facing elevated risks of mortality, patients with comorbid HF with reduced EF and kidney disease are not optimally treated with evidence-based medical therapies, even at levels of eGFR where such therapies would not be contraindicated by kidney dysfunction. Further efforts are required to mitigate risk in comorbid HF and kidney disease.

Background and Purpose: Patients with pre-stroke mobility impairment were excluded from endovascular clinical trials. There is limited data regarding safety and outcomes of endovascular thrombectomy (EVT) in this population. We used a large, national dataset (Get With The Guidelines (GWTG)-Stroke) to evaluate the safety and outcomes of EVT in patients with pre-stroke mobility impairment (PSMI). Methods: We included patients who underwent EVT in the GWTG-Stroke registry between 2015 and 2019. PSMI was defined as inability to ambulate independently and poor outcome was defined as in-hospital mortality or discharge to hospice. GEE logistic regression models were used to evaluate the association between PSMI and outcomes. Results: Of 56,762 patients treated with EVT, 2919 (5.14%) had PSMI. Patients with PSMI were older (median 79 [IQR 70-87] vs 70 [59-80], P80 years and NIHSS >20 had a poor outcome. Conclusions: Amongst patients with PSMI treated with EVT, two thirds survived and one third were discharged to home or to inpatient rehabilitation. Advanced age and increased stroke severity increased the likelihood of poor outcomes. EVT appears safe in patients with PSMI, yet further study of effectiveness in this population is warranted.
