Inspiratory Muscle Training and Functional Electrical Stimulation for Treatment of Heart Failure With Preserved Ejection Fraction: The TRAINING-HF Tr…

2019

Introduction and objectives: Despite the prevalence of heart failure with preserved ejection fraction (HFpEF), there is currently no evidence-based effective therapy for this disease. This study sought to evaluate whether inspiratory muscle training (IMT), functional electrical stimulation (FES), or a combination of both (IMT + FES) improves 12- and 24-week exercise capacity as well as left ventricular diastolic function, biomarker profile, and quality of life in HFpEF. Methods: A total of 61 stable symptomatic patients (New York Heart Association II-III) with HFpEF were randomized (1:1:1:1) to receive a 12-week program of IMT, FES, or IMT + FES vs usual care. The primary endpoint of the st…

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…

International Normalized Ratio and Mortality Risk in Acute Heart Failure and Nonvalvular Atrial Fibrillation Patients Receiving Vitamin K Antagonists

2019

Introduction and objectives: Heart failure patients with nonvalvular atrial fibrillation (NVAF) on treatment with vitamin K antagonists (VKA) often have suboptimal international normalized ratio (INR) values. Our aim was to evaluate the association between INR values at admission due to acute heart failure and mortality risk during follow-up. Methods: In this observational study, we retrospectively assessed INR on admission in 1137 consecutive patients with acute heart failure and NVAF who were receiving VKA treatment. INR was categorized into optimal values (INR = 2-3, n = 210), subtherapeutic (INR 3, n = 267). Because INR did not meet the proportional hazards assumption for mortality, res…

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 …

Diuretic Strategies in Acute Heart Failure and Renal Dysfunction: Conventional vs Carbohydrate Antigen 125-guided Strategy. Clinical Trial Design

2017

Abstract Introduction and objectives The optimal treatment of patients with acute heart failure (AHF) and cardiorenal syndrome type 1 (CRS-1) is far from being well-defined. Arterial hypoperfusion in concert with venous congestion plays a crucial role in the pathophysiology of CRS-I. Plasma carbohydrate antigen 125 (CA125) has emerged as a surrogate of fluid overload in AHF. The aim of this study was to evaluate the clinical usefulness of CA125 for tailoring the intensity of diuretic therapy in patients with CRS-1. Methods Multicenter, open-label, parallel clinical trial, in which patients with AHF and serum creatinine ≥ 1.4 mg/dL on admission will be randomized to: a) standard diuretic str…

SEC 2017: Congreso de las Enfermedades Cardiovasculares Introducción y objetivos No se dispone de tratamientos farmacológicos que demuestren reducir la morbimortalidad asociada en pacientes con insuficiencia cardiaca y función sistólica conservada (IC-FEc). El objetivo del presente estudio fue evaluar si en pacientes con IC-FEc, el entrenamiento de la musculatura inspiratoria (EMI), la electroestimulación muscular funcional (EMF) o la combinación de ambas (EMI + EMF) puede mejorar la capacidad funcional, calidad de vida, parámetros de disfunción diastólica o biomarcadores a las 12 y 24 semanas. Métodos Un total de 61 pacientes estables con IC-FEc (clase funcional de la New York Heart Associ…

2019

Resumen Introduccion y objetivos Los pacientes con insuficiencia cardiaca en tratamiento con antagonistas de la vitamina K (AVK) por fibrilacion auricular no valvular (FANV) a menudo presentan valores alterados de la razon internacional normalizada (INR). El objetivo es evaluar la asociacion entre la INR al ingreso por insuficiencia cardiaca y el riesgo de mortalidad en el seguimiento. Metodos Estudio observacional retrospectivo en el que se evaluo la INR al ingreso de 1.137 pacientes consecutivos con insuficiencia cardiaca aguda en tratamiento con AVK por FANV. Esta se categorizo en: INR en rango optimo (INR = 2-3, n = 210), infraterapeutica (INR 3, n = 267). La asociacion independiente en…

Estrategias diuréticas en insuficiencia cardiaca aguda con disfunción renal: terapia convencional frente a guiada por el antígeno carbohidrato 125. D…

2017

Resumen Introduccion y objetivos El tratamiento optimo de pacientes con insuficiencia cardiaca aguda (ICA) y sindrome cardiorrenal tipo 1 (SCR-1) no esta bien definido. La hipoperfusion arterial y la congestion venosa tienen un papel fundamental en la fisiopatologia del SCR-1. El antigeno carbohidrato 125 (CA125) ha emergido como marcador indirecto de sobrecarga de volumen en la ICA. El objetivo de este estudio es evaluar la utilidad del CA125 para el ajuste del tratamiento diuretico de pacientes con SCR-1. Metodos Ensayo clinico multicentrico, abierto y paralelo, que incluye a pacientes con ICA y creatinina ≥ 1,4 mg/dl al ingreso, aleatorizados a: a)  estrategia convencional: titulacion ba…

Right Ventricular Dysfunction Staging System for Mortality Risk Stratification in Heart Failure with Preserved Ejection Fraction

2020

Right ventricular dysfunction (RVD) parameters are increasingly important features in heart failure with preserved ejection fraction (HFpEF). We sought to evaluate the prognostic impact of a progressive RVD staging system by combining the tricuspid annular plane systolic excursion (TAPSE) to pulmonary artery systolic pressure (TAPSE/PASP) ratio with functional tricuspid regurgitation (TR) severity. We prospectively included 1355 consecutive HFpEF patients discharged for acute heart failure (HF). Of them, in 471 (34.7%) patients, PASP could not be accurately measured, leaving the final sample size to be 884 patients. Patients were categorized as Stage 1: TAPSE/PASP &ge

Inspiratory Muscle Training and Functional Electrical Stimulation for Treatment of Heart Failure With Preserved Ejection Fraction: Rationale and Stud…

2016

Heart failure with preserved ejection fraction (HFpEF) has become the most prevalent form of heart failure in developed countries. Regrettably, there is no evidence-based effective therapy for HFpEF. We seek to evaluate whether inspiratory muscle training, functional electrical stimulation, or a combination of both can improve exercise capacity as well as left ventricular diastolic function, biomarker profile, quality of life (QoL), and prognosis in patients with HFpEF. A total of 60 stable symptomatic patients with HFpEF (New York Heart Association class II-III/IV) will be randomized (1:1:1:1) to receive a 12-week program of inspiratory muscle training, functional electrical stimulation, a…

Use of acetazolamide in the treatment of patients with refractory congestive heart failure

2018

Aims Optimal diuretic treatment of patients with refractory congestive heart failure (CHF) remains to be elucidated. In this work, we aimed to evaluate the serial changes of functional class and surrogates of fluid overload (weight and antigen carbohydrate 125) after addition of oral acetazolamide in patients with refractory CHF. Likewise, serial changes in renal function, serum electrolytes and pH were evaluated. Method This is an observational retrospective study in which 25 ambulatory patients with refractory CHF that received acetazolamide in addition to standard intensive diuretic strategy were evaluated. Longitudinal assessment of New York Heart Association (NYHA) functional class and…
