Right Heart Dysfunction and Readmission Risk Across Left Ventricular Ejection Fraction Status in Patients With Acute Heart Failure.
2021
BACKGROUND: Right heart dysfunction (RHD) parameters are increasingly important in heart failure (HF). This study aimed to evaluate the association of advanced RHD with the risk of recurrent admissions across the spectrum of left ventricular ejection fraction (LVEF). METHODS AND RESULTS: We included 3383 consecutive patients discharged for acute HF. Of them, in 1435 patients (42.4%), the pulmonary artery systolic pressure could not be measured accurately, leaving a final sample size of 1948 patients. Advanced RHD was defined as the combination of a ratio of tricuspid annular plane systolic excursion/pulmonary artery systolic pressure of less than 0.36 and significant tricuspid regurgitation…
Sex-related differences in mortality following an admission for acute heart failure across left ventricular ejection fraction spectrum
2021
Abstract Background Prognosis in heart failure (HF) may differ between women and men. However, data is conflicting and sex-related differences in prognosis may be determined by left ventricular ejection fraction (LVEF) status. We sought to evaluate the prognostic differences between women and men with HF following an admission for acute HF (AHF). Methods We included 4,812 patients consecutively admitted for AHF in a multicenter registry from 3 hospitals in Valencia (Spain). Study endpoints were all-cause, cardiovascular (CV), and HF-related mortality at 6-months follow-up. Multivariable Cox regression models were fitted to investigate sex-related differences across LVEF status. Results 2,24…
Right heart dysfunction and readmission risk across left ventricular ejection fraction status in patients with acute heart failure
2021
Abstract Background Right heart dysfunction (RHD) parameters, such as right ventricular to pulmonary artery uncoupling or significant tricuspid regurgitation (TR) are increasingly important in heart failure (HF), especially in patients with preserved ejection fraction. In this study, we aimed to evaluate the association of advanced RHD with the risk of recurrent admissions across the spectrum of left ventricular ejection fraction (LVEF). Methods We included 3,383 consecutive patients discharged for acute HF (AHF). Of them, in 1,435 (42.4%) pulmonary artery systolic pressure (PASP) could not be accurately measured, leaving a final sample size of 1,948 patients. Advanced RHD was defined as th…
Effects of empagliflozin on CA125 trajectory in patients with chronic congestive heart failure
2021
INTRODUCTION: We aimed to evaluate the trajectory of two surrogates of fluid overload -antigen carbohydrate 125 (CA125) and amino-terminal pro-brain natriuretic peptide (NT-proBNP)- after the addition of oral empagliflozin to usual care in a cohort of patients with chronic heart failure (CHF) and type 2 diabetes (T2D). METHODS AND RESULTS: From October 2015 to February 2019, 60 ambulatory patients with CHF and T2D were retrospectively included. The primary endpoint was to assess the longitudinal trajectory of plasma levels of CA125 and NT-proBNP after empagliflozin initiation. Changes in quantitative variables were evaluated using linear mixed regression. Median CA125 and NT-proBNP at basel…
Clinical profile and 1-year clinical outcomes of super elderly patients admitted with acute heart failure
2020
There is scarce information about the clinical profile and prognosis of acute heart failure (AHF) at the extreme ranges of age. We aimed to evaluate the 1-year death (all-cause mortality and HF-death) and HF-rehospitalizations of patients ≥85 years admitted for AHF.We prospectively evaluated a cohort of 3054 patients admitted with AHF from 2007 to 2018 in a third-level center. Age was categorized per 10-year categories (65 years; 65-74 years, 75-84 years, and ≥85 years). The risk of mortality and HF-rehospitalizations across age categories was evaluated with Cox regression analysis and Cox regression adapted for competing events as appropriate.The mean age was 73.6 ± 11.2 years, 48.9% were …
Clinical utility of antigen carbohydrate 125 for planning the optimal length of stay in acute heart failure.
2021
BACKGROUND: The optimal length of stay (LOS) in patients hospitalized for acute heart failure (AHF) remains controversial. Plasma antigen carbohydrate 125 (CA125) has emerged as a reliable proxy of congestion. We aimed to evaluate whether there is a differential impact of LOS on the risk of 6-month AHF readmission across CA125 levels. METHODS: This is a retrospective study that included 1,387 patients discharged for AHF in two third-level centers. CA125 was measured 48±24h after admission. The association between CA125 and LOS with the risk of subsequent AHF readmission at 6 months was analyzed by Cox regression analysis accounting for death as a competing event. RESULTS: The median (IQR) a…
Right ventricular function and iron deficiency in acute heart failure
2021
Abstract Aims Iron deficiency (ID) is a frequent finding in patients with chronic and acute heart failure (AHF) along the full spectrum of left ventricular ejection fraction (LVEF). Iron deficiency has been related to ventricular systolic dysfunction, but its role in right ventricular function has not been evaluated. We sought to evaluate whether ID identifies patients with greater right ventricular dysfunction in the setting of AHF. Methods and results We prospectively included 903 patients admitted with AHF. Right systolic function was evaluated by tricuspid annular plane systolic excursion (TAPSE) and the ratio TAPSE/pulmonary artery systolic pressure (TAPSE/PASP). Iron deficiency was de…
Early urinary sodium trajectory and risk of adverse outcomes in acute heart failure and renal dysfunction.
2021
Introduction and objectives: Urinary sodium (UNa+) has emerged as a useful biomarker of poor clinical outcomes in acute heart failure (AHF). Here, we sought to evaluate: a) the usefulness of a single early determination of UNa+ for predicting adverse outcomes in patients with AHF and renal dysfunction, and b) whether the change in UNa+ at 24 hours (Delta UNa24 h) adds any additional prognostic information over baseline values. Methods: This is a post-hoc analysis of a multicenter, open-label, randomized clinical trial (IMPROVE-HF) (ClinicalTrials.gov NCT02643147) that randomized 160 patients with AHF and renal dysfunction on admission to a) the standard diuretic strategy, or b) a carbohydra…
Trayectoria precoz del sodio urinario y riesgo de eventos adversos en insuficiencia cardiaca aguda y disfunción renal
2021
Resumen Introduccion y objetivos El sodio urinario (UNa+) ha surgido como un biomarcador util para predecir eventos clinicos desfavorables en pacientes con insuficiencia cardiaca aguda (ICA). En este estudio pretendemos evaluar: a) la utilidad de una unica determinacion precoz de UNa+ para predecir eventos adversos en pacientes con ICA e insuficiencia renal (IR) concomitante, y b) si los cambios en el UNa+ a las 24 horas (ΔUNa24 h) anaden informacion pronostica adicional sobre los valores basales. Metodos Analisis post-hoc del ensayo clinico multicentrico, abierto y paralelo (IMPROVE-HF), (ClinicalTrials.gov NCT02643147) en el que 160 pacientes con ICA e IR concomitante al ingreso fueron al…
Effect of insulin on readmission for heart failure following a hospitalization for acute heart failure
2020
AIMS: Type 2 diabetes mellitus (T2DM) is common in patients with heart failure (HF) and is related with worse outcomes. Insulin treatment is associated with sodium and water retention, weight gain, and hypoglycaemia-all pathophysiological mechanisms related to HF decompensation. This study aimed to evaluate the association between insulin treatment and the risk of 1year readmission for HF in patients discharged for acute HF.; METHODS AND RESULTS: We prospectively included 2895 consecutive patients discharged after an episode of acute HF in a single tertiary hospital. Multivariable Cox regression, adapted for competing events, was used to assess the association between insulin treatment and …
