Abstract 278: Phenomapping of Worsening Renal Function During Hospitalization for Acute Heart Failure

Background: Worsening renal function (WRF) during the hospitalization has been recognized as a predictor for worse outcomes in patients with acute heart failure (AHF). However, in recent years, elevation of serum creatinine during the acute phase of the treatment is accepted as a sign of efficient decongestion. Herein, we aimed to evaluate the phenotypic difference in this heterogeneous phenomenon by using clustering analysis. Methods: A total of 4000 patient data from the West-Tokyo Heart Failure Registry, a multicenter, prospective registry for consecutive AHF hospitalization were analyzed. Within 632 patients identified to have WRF (17%; defined as elevation of eGFR over 20 percent during the hospitalization), we applied two-step clustering analysis of phenotypic data (37 variables) to define and characterize phenotypically distinct population. After identification of phenotypically distinct subgroups, survival analysis with Cox proportional hazard was conducted to elucidate the impact of the classification on composite outcomes of heart failure re-hospitalization and all cause death. Results: The analysis identified four distinct populations (group 1-4) that distinctly differed in terms of clinical characteristics: Group1 composed of patients with reduced ejection fraction (EF), while group 2 to 4 were composed of patients with mid-range and preserved EF. Group 1 patients also had lowest eGFR and blood pressure at the time of admission. Group 1 and 2 patients were younger, but had higher plasma BNP compared to 3 and 4. Among these subgroups, group 1 had the worst, and group 2 had the most favorable prognosis. The difference in prognosis between these two groups was significant after adjustments with known prognostic factors (hazard ratio, 0.58; 95 percent confidence interval, 0.35-0.97). Conclusion: WRF represents heterogeneous condition; our clustering analysis revealed four phenotypically distinct population with significant difference in their prognosis. Further investigation is needed to assess its therapeutic implication.

ObjectivesCardiorenal syndrome (CRS) is the combination of acute heart failure syndrome (AHF) and renal dysfunction (creatinine clearance (CrCl) ≤60 mL/min). Real-life data were used to compare the management and outcome of AHF with and without renal dysfunction.DesignProspective, multicentre.SettingTwenty-six academic, community and regional hospitals in France.Participants507 patients with AHF were assessed in two groups according to renal function: group 1 (patients with CRS (CrCl ≤60 mL/min): n=335) and group 2 (patients with AHF with normal renal function (CrCl >60 mL/min): n=172).ResultsDifferences were observed (group 1 vs group 2) at admission for the incidence of chronic heart failure (56.42% vs 47.67%), use of furosemide (60.9% vs 52.91%), insulin (15.52% vs 9.3%) and amiodarone (14.33% vs 4.65%); additionally, more patients in group 1 carried a defibrillator (4.78% vs 0%), had ≥2 hospitalisations in the last year (15.52% vs 5.81%) and were under the care of a cardiologist (72.24% vs 61.63%). Clinical signs were broadly similar in each group. Brain-type natriuretic peptide (BNP) and BNP prohormone were higher in group 1 than group 2 (1157.5 vs 534 ng/L and 5120 vs 2513 ng/mL), and more patients in group 1 were positive for troponin (58.2% vs 44.19%), had cardiomegaly (51.04% vs 37.21%) and interstitial opacities (60.3% vs 47.67%). The only difference in emergency treatment was the use of nitrates, (higher in group 1 (21.9% vs 12.21%)). In-hospital mortality and the percentage of patients still hospitalised after 30 days were similar between groups, but the median stay was longer in group 1 (8 days vs 6 days).ConclusionsRenal impairment in AHF should not limit the use of loop diuretics and/or vasodilators, but early assessment of pulmonary congestion and close monitoring of the efficacy of conventional therapies is encouraged to allow rapid and appropriate implementation of alternative therapies if necessary.

Background: The number of coronary chronic total occlusion (CTO) patients with renal insufficiency is huge, and limited data are available on the impact of renal insufficiency on long-term clinical outcomes in CTO patients. We aimed to investigate clinical outcomes of CTO percutaneous coronary intervention (PCI) vs. medical therapy (MT) in CTO patients according to baseline renal function.Methods: In the study population of 2,497, 1,220 patients underwent CTO PCI and 1,277 patients received MT. Patients were divided into four groups based on renal function: group 1 [estimated glomerular filtration rate (eGFR) ≥ 90 ml/min/1.73 m2], group 2 (60 ≤ eGFR <90 ml/min/1.73 m2), group 3 (30 ≤ eGFR <60 ml/min/1.73 m2), and group 4 (eGFR <30 ml/min/1.73 m2). Major adverse cardiac event (MACE) was the primary end point.Results: Median follow-up was 2.6 years. With the decline in renal function, MACE (p < 0.001) and cardiac death (p < 0.001) were increased. In group 1 and group 2, MACE occurred less frequently in patients with CTO PCI, as compared to patients in the MT group (15.6% vs. 22.8%, p < 0.001; 15.6% vs. 26.5%, p < 0.001; respectively). However, there was no significant difference in terms of MACE between CTO PCI and MT in group 3 (21.1% vs. 28.7%, p = 0.211) and group 4 (28.6% vs. 50.0%, p = 0.289). MACE was significantly reduced for patients who received successful CTO PCI compared to patients with MT (16.7% vs. 22.8%, p = 0.006; 16.3% vs. 26.5%, p = 0.003, respectively) in group 1 and group 2. eGFR < 30 ml/min/1.73 m2, age, male gender, diabetes mellitus, heart failure, multivessel disease, and MT were identified as independent predictors for MACE in patients with CTOs.Conclusions: Renal impairment is associated with MACE in patients with CTOs. For treatment of CTO, compared with MT alone, CTO PCI may reduce the risk of MACE in patients without chronic kidney disease (CKD). However, reduced MACE from CTO PCI among patients with CKD was not observed. Similar beneficial effects were observed in patients without CKD who underwent successful CTO procedures.

Introduction: Worsening renal function (WRF) predicts poor prognosis in patients with left ventricular systolic dysfunction. The effect of WRF in heart failure with preserved ejection fraction (HFpEF) is unclear. Objective: The objective of this study was to determine whether WRF during index hospitalization for HFpEF is associated with increased death or readmission for heart failure. Methods: National Veterans Affairs electronic medical data recorded between January 1, 2002, and December 31, 2014, were screened to identify index hospitalizations for HFpEF using an iterative algorithm. Patients were divided into 3 groups based on changes in serum Cr (sCr) during this admission. WRF was defined as a rise in sCr ≥0.3 mg/dL. Group 1 had no evidence of WRF, group 2 had transient WRF, and group 3 had persistent WRF at the time of discharge. Results: A total of 10,902 patients with index hospitalizations for HFpEF were identified (mean age 72, 97% male). Twenty-nine percent had WRF during this hospital admission, with 48% showing recovery of sCr and 52% with no recovery at discharge. The mortality rate over a mean follow-up duration of 3.26 years was 72%. Compared to group 1, groups 2 and 3 showed no significant difference in risk of death from any cause (hazard ratio [HR] = 0.95 [95% confidence interval [CI]: 0.87, 1.03] and 1.02 [95% CI: 0.93, 1.11], respectively), days hospitalized for any cause (incidence density ratio [IDR] = 1.01 [95% CI: 0.92, 1.11] and 1.01 [95% CI: 0.93, 1.11], respectively), or days hospitalized for heart failure (IDR = 0.94 [95% CI: 0.80, 1.10] and 0.94 [95% CI: 0.81, 1.09], respectively) in analyses adjusted for covariates affecting renal function and outcomes. Conclusions: While there is a high incidence of WRF during index hospitalizations for HFpEF, WRF is not associated with an increased risk of death or hospitalization. This suggests that WRF alone should not influence decisions regarding heart failure management.

As commonly happens in epidemiological research, none of the reported studies were totally free of methodological problems. Studies have considered the influence of social relationships on dementia, but the mechanisms underlying these associations are not perfectly understood. We look at the possible impact of selection bias. For their first memory consultation, patients may come alone or accompanied by a relative. Our objective is to better understand the impact of this factor by retrospective follow-up of geriatric memory outpatients over several years. All patients over 70 who were referred to Bretonneau Memory Clinic for the first time, between January 2006 and 2018, were included in the study. The patients who came alone formed group 1, the others, whatever type of relative accompanied them, formed group 2. We compared the Mini-Mental State Examination (MMSE) scores of patients; and for all patients who came twice for consultation with at least a 60-day interval, we compared their first MMSE with the MMSE performed at the second consultation. In total, 2,935 patients were included, aged 79.7 ± 8.4 years. Six hundred and twenty-five formed group 1 and 2,310 group 2. We found a significant difference in MMSE scores between the 2 groups of patients; and upon second consultation in group 2, but that difference was minor in group 1. Our finding of a possible confounding factor underlines the complexity of choosing comparison groups in order to minimize selection bias while maintaining clinical relevance.

INTRODUCTION As virtual education becomes more widespread, particularly considering the recent COVID-19 pandemic, studies that assess the impact of online teaching strategies are vital. Current anatomy curriculum at Paul L. Foster School of Medicine consists of self-taught PowerPoint material, clinical vignette-centered team-based learning (dry lab), and prosection-based instruction (wet lab). This study examined the impact of video-based muscle model (VBMM) instruction using a student-designed forearm muscle model on anatomy quiz scores and student perceptions of its effectiveness with regards to learning outcomes. METHODS Students divided into Group 1 (54 students) and Group 2 (53 students) were assessed prior to and following a 3.5-minute video on anterior forearm compartment musculature using the muscle model. Group 1 began by completing a pretest, then received VBMM instruction, and then completed a posttest prior to participating in the standard dry lab and 1 hour wet lab. Group 2 completed the wet lab, then received the pretest, VBMM instruction, and posttest prior to participating in the dry lab. Both groups took an identical five-question quiz covering locations and functions of various anterior forearm muscles each time. RESULTS Mean scores were higher than no formal intervention with exposure to VBMM instruction alone (0.73 points, P = .01), wet lab alone (0.88 points, P = .002), and wet lab plus VBMM instruction (1.35 points, P= <.001). No significant difference in scores was found between instruction with VBMM versus wet lab alone ( P = 1.00), or between either instruction method alone compared to a combination of the two methods ( P = .34, .09). Student survey opinions on the VBMM instruction method were positive. CONCLUSION VBMM instruction is comparable to prosection-based lab with regards to score outcomes and was well received by students as both an independent learning tool and as a supplement to cadaveric lab. When compared to either instruction method alone, the supplementation of VBMM with cadaveric prosection instruction was best. VBMM instruction may be valuable for institutions without access to cadaveric specimens, or those looking to supplement their current anatomy curriculum.
