Introduction: Hyper- and hypo-kalemia have each been associated with higher risk of death in in heart failure with reduced ejection fraction but the relationship between serum potassium and risk of death in heart failure with preserved ejection fraction (HFpEF) is not well established. We assessed the risk associated with high and low potassium in patients with HFpEF enrolled in the PARAGON-HF trial. Aim: To explore the association between serum potassium and mortality in patients with HFpEF and examine the interaction with renal function. Methods: Repeated events, Cox and mixed-effects models. The primary outcome in this analysis was death from any cause. Results: Patients: mean age 73 years, 52% female. Higher potassium was not associated with higher risk of death: adjusted time-updated HR (95%CI) for potassium >5.0 mmol/l =1.06 (0.85-1.32); p=0.61 (potassium 4-5 mmol/l referent HR=1.0). However, lower potassium was associated with higher risk of death: adjusted HR for potassium <4.0 mmol/l=1.51 (1.21-1.87); p<0.001. However, the risk related to potassium was modified by baseline renal function (p for interaction <0.05), whereby the excess mortality in patients with low potassium was most prominent in patients with an eGFR <60 ml/min/1.73m 2 (Figure). Conclusion: In adjusted analyses, low potassium was independently associated with mortality in patients with HFpEF, especially in the context of renal impairment.

Purpose: i) To determine the relationship between the cardiac biomarkers ST2 and NT-proBNP with ejection fraction (EF) in heart failure (HF) patients. ii) Assess whether a superiority existed between the aforementioned cardiac markers in diagnosing the HF with reduced EF. iii) Determine the efficacy of both biomarkers in predicting a 30-day cardiovascular event and rehospitalization in patients with HF with reduced EF iv) To assess the influence of age, gender, BMI, anaemia and renal failure on the ST2 and NT-proBNP levels. Design and Methods: A prospective double-blind study was conducted to obtain data from a sample of 64 cardiology patients. A blood sample was collected to test for ST2 and NT-proBNP. An echocardiogram (to obtain EF value), electrocardiogram and questionnaire were also obtained. Results: Of the 64 patients enrolled, 59.4% of the population had an EF less than 40%. At the end of the 30- day period, 7 patients were warded, 37 were not warded, one died and 17 were non respondent. Both biomarkers were efficacious at diagnosing HF with a reduced EF. However, neither of them were efficacious in predicting 30-day rehospitalization. The mean NT-proBNP values being: not rehospitalized (2114.7486) and 30 day rehospitalization (1008.42860) and the mean ST2 values being: not rehospitalized (336.1975), and 30-day rehospitalization. (281.9657). Conclusion: Neither ST2 or NT-proBNP was efficacious in predicting the short- term prognosis in HF with reduced EF. Both however were successful at confirming the diagnosis of HF in HF patients with reduced EF.

Abstract Background Acute heart failure is a life-threatening clinical condition. Levosimendan is an effective inotropic agent used to maintain cardiac output, but its usage is limited by the lack of evidence in patients with severely abnormal renal function. Therefore, we analyzed data of patients with acute heart failure with and without abnormal renal function to examine the effects of levosimendan. Methods We performed this retrospective cohort study using data from the Chang Gung Research Database (CGRD) of Chang Gung Memorial Hospital (CGMH). Patients admitted for heart failure with LVEF ≤ 40% between January 2013 and December 2018 who received levosimendan or dobutamine in the critical cardiac care units (CCU) were identified. Patients with extracorporeal membrane oxygenation (ECMO) were excluded. Outcomes of interest were mortality at 30, 90, and 180 days after the cohort entry date. Results There were no significant differences in mortality rate at 30, 90, and 180 days after the cohort entry date between the levosimendan and dobutamine groups, or between subgroups of patients with an estimated glomerular filtration rate (eGFR) ≥ 30 mL/min/1.73 m2 and eGFR < 30 mL/min/1.73 m2 or on dialysis. The results were consistent before and after propensity score matching. Conclusions Levosimendan did not increase short- or long-term mortality rates in critical patients with acute heart failure and reduced ejection fraction compared to dobutamine, regardless of their renal function. An eGFR less than 30 mL/min/1.73 m2 was not necessarily considered a contraindication for levosimendan in these patients.

<b><i>Introduction:</i></b> 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. <b><i>Objective:</i></b> 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. <b><i>Methods:</i></b> 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. <b><i>Results:</i></b> 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. <b><i>Conclusions:</i></b> 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.

The angiotensin receptor neprilysin inhibitor (ARNI) has been recommended as a first-line treatment in patients with heart failure (HF). However, the effects of ARNI on renal function remain controversial.The PubMed, Embase, the Cochrane Library of Trials and Web of Science were searched in the period from inception to 31 January 2021. Randomised controlled trial, cohort studies and observational studies reporting at least one of renal function indicators were included.In patients with HF with reduced ejection fraction (HFrEF), ARNI did not lead to a significant decrease in estimated glomerular filtration rate (eGFR, p=0.87), and the risk of worsening renal function (WRF) dropped by 11% compared with control group. Though the level of serum creatinine (SCr) and serum potassium had a slight increase (p=0.01; p=0.02), in contrast to the baseline level, but without clinical significance. In patients with HF with preserved ejection fraction (HFpEF), the level of SCr and serum potassium did not have a significant change, and patients with HFpEF assigned to ARNI had a much lower rate of WRF (p=0.0007). In contrast to control group, both patients with HFrEF and HFpEF had a less decrease in eGFR and a lower rate of hyperkalaemia in ARNI group.ARNI did not lead to a significant decrease in eGFR in HFrEF. Compared with control group, ARNI could delay the progression of decrease in eGFR and result in less events of hyperkalaemia in patients with HF. Besides, patients with HFpEF had a lower rate in the events of WRF.

Abstract Funding Acknowledgements none Aims. To evaluate the effects of Sacubitril/Valsartan (S/V) on clinical, laboratory and echocardiographic parameters and outcomes in a real-world population with heart failure with reduced ejection fraction (HFrEF). Methods and results. Prospective study enrolling consecutive patients with HFrEF treated with S/V.The primary outcome was HF rehospitalization;secondary outcomes were all-cause death, cardiac death and the composite of cardiac death and HF rehospitalization at 12 months follow up.The clinical outcome was compared with a retrospective cohort of 90 HFrEF patients treated with standard medical therapy by using propensity score weighting. At 6 months follow-up, changes in symptoms, echocardiographic parameters, eGFR and furosemide dose were also evaluated. The study population consisted of 90 patients (66.1 ± 11.7 years). At 6 months FU, a significant improvement in NYHA class, LVEF (from 31.0% to 34.0%; p = 0.001), LVESV (from 115.0 to 101.0 mL; p = 0.033) and sPAP (from 31.0 to 25.0 mmHg; p = 0.024) was observed. Moreover, S/V did not affect negatively eGFR and was associated with a significantly lower dose of furosemide prescribed. The propensity score weighting adjusted regression analysis showed a significantly lower risk for HF rehospitalization (HR, 0.131; 95% CI, 0.034-0.503; p = 0.003) and the composite outcome (HR, 0.162; 95% CI, 0.053-0.492; p = 0.001) among patients treated with S/V as compared to the standard therapy group. Conclusions In this real-world HFrEF population, S/V reduced HF rehospitalization and cardiac death at 1 year. Moreover, S/V improved significantly NYHA class, LVEF, LVESV and sPAP at 6 months, preserving renal function and reducing the need of furosemide.

Background: Empagliflozin reduces the risk of cardiovascular death or hospitalization for heart failure in patients with heart failure and a reduced ejection fraction, with or without diabetes, but additional data are needed about the effect of the drug on inpatient and outpatient events that reflect worsening heart failure. Methods: We randomly assigned 3730 patients with class II-IV heart failure with an ejection fraction of ≤40% to double-blind treatment with placebo or empagliflozin (10 mg once daily), in addition to recommended treatments for heart failure, for a median of 16 months. We prospectively collected information on inpatient and outpatient events reflecting worsening heart failure and prespecified their analysis in individual and composite endpoints. Results: Empagliflozin reduced the combined risk of death, hospitalization for heart failure or an emergent/urgent heart failure visit requiring intravenous treatment (415 vs 519 patients; empagliflozin vs placebo, respectively; hazard ratio 0.76, 95% CI: 0.67-0.87), P <0.0001. This benefit reached statistical significance at 12 days after randomization. Empagliflozin reduced the total number of heart failure hospitalizations that required intensive care (hazard ratio 0.67, 95% CI 0.50-0.90, P=0.008) and that required a vasopressor or positive inotropic drug or mechanical or surgical intervention (hazard ratio 0.64, 95% CI: 0.47-0.87, P=0.005). As compared with placebo, fewer patients in the empagliflozin group reported intensification of diuretics (297 vs 414), hazard ratio 0.67, 95% CI: 0.56-0.78, P<0.0001. Additionally, patients assigned to empagliflozin were 20-40% more likely to experience an improvement in NYHA functional class and were 20-40% less likely to experience worsening of NYHA functional class, with statistically significant effects that were apparent 28 days after randomization and maintained during long-term follow-up. The risk of any inpatient or outpatient worsening heart failure event in the placebo group was high (48.1 per 100 patient-years of follow-up), and it was reduced by empagliflozin (hazard ratio 0.70, 95% CI: 0.63-0.78), P<0.0001. Conclusions: In patients with heart failure and a reduced ejection fraction, empagliflozin reduced the risk and total number of inpatient and outpatient worsening heart failure events, with benefits seen early after initiation of treatment and sustained for the duration of double-blind therapy.
