La congestión residual y la intuición clínica en la insuficiencia cardiaca descompensada

Congestive symptoms are the key to recognising decompensated heart failure, whose treatment is based on reducing the congestion until a clinical situation has been reached that allows the patient to be discharged to continue outpatient treatment. The important aspect is not the degree of congestion at admission but rather the congestion that persists after energetic diuretic therapy. The persistence of congestive signs following an apparently correct and effective therapy has been called residual congestion and is associated with a poor prognosis. The tools for determining this condition are still rudimentary. Methods therefore need to be developed that enable a more accurate assessment

Valor pronóstico de la desnutrición en pacientes con insuficiencia cardíaca aguda y su influencia en la interpretación de marcadores de congestión venosa sistémica

Antecedentes La desnutrición es frecuente en los pacientes con insuficiencia cardíaca (IC). Dicha situación contribuye al incremento de la congestión sistémica dificultando el manejo clínico. Cuantificar la desnutrición y su relación con la congestión sistémica, es importante para optimizar el tratamiento durante la fase aguda. Material y métodos Estudio de cohortes retrospectivo en pacientes con diagnóstico de IC aguda. La población se estratificó según los índices de nutrición de CONUT (Controlling Nutritional Status) y PNI (Prognostic Nutritional Index) con el objetivo de analizar su relación con parámetros objetivos de congestión y el valor pronóstico al año de seguimiento. Resultados Se incluyeron un total de 309 pacientes, presentando más de la mitad algún grado de desnutrición al ingreso. El grado de congestión fue significativamente superior en los pacientes desnutridos, con una mayor proporción de «líneas b» y un mayor volumen plasmático relativo. Las concentraciones de la prohormona N-terminal del péptido natriurético cerebral (NT-proBNP), tanto al ingreso como al alta, también fueron significativamente superiores en los pacientes desnutridos, independientemente de la escala empleada. El análisis univariante identificó el índice de CONUT y PNI, como factores asociados a la mortalidad al año para todas las causas (HR 1, 62 [1, 22-2, 14]; p = 0, 001) y de PNI (HR 0, 65 [0, 53-0, 80]; p = < 0, 001), respectivamente. Conclusiones Un mayor grado de desnutrición (determinado mediante los índices de CONUT y PNI) en pacientes con IC aguda, se asoció a una mayor presencia de parámetros objetivos de congestión y a una mayor mortalidad al año para todas las causas. Background Malnutrition is frequent in patients with heart failure (HF) and contributes to increased systemic congestion, but also hinders its correct assessment, especially during decompensations. Estimating the degree of malnutrition and its relationship with systemic congestion is important to optimize treatment during decompensations. Material and methods Retrospective cohort study in patients with acute HF. The population was stratified according to CONUT (Controlling Nutritional Status) and PNI (Prognostic Nutritional Index) nutrition indices in order to analyse their relationship with objective parameters of congestion and the prognostic value of malnutrition. Results 309 patients were included. More than half presented some degree of malnutrition upon admission. The degree of congestion was significantly higher in malnourished patients, with a higher proportion of «comet tail artifacts» and a higher relative plasma volume. NT-proBNP concentrations, both on admission and at discharge, were also significantly higher in malnourished patients, regardless of the scale used. The univariate analysis identified the CONUT and PNI index as factors associated with one-year mortality from any cause (HR 1.62 [1.22-2.14]; p = 0.001) and PNI (HR 65 [0.53-0.80]; p = < 0.001), respectively. Conclusions A higher degree of malnutrition (determined by means of the CONUT and PNI indices) in patients with acute HF was associated with a higher presence of objective parameters of congestion and a higher one-year all-cause mortality

Design and baseline characteristics of SALT-HF trial: hypertonic saline therapy in ambulatory heart failure

Aims: Hypertonic saline solution (HSS) plus intravenous (IV) loop diuretic appears to enhance the diuretic response in patients hospitalized for heart failure (HF). The efficacy and safety of this therapy in the ambulatory setting have not been evaluated. We aimed to describe the design and baseline characteristics of the SALT-HF trial participants. Methods and results: ‘Efficacy of Saline Hypertonic Therapy in Ambulatory Patients with HF’ (SALT-HF) trial was a multicenter, double-blinded, and randomized study involving ambulatory patients who experienced worsening heart failure (WHF) without criteria for hospitalization. Enrolled patients had to present at least two signs of volume overload, use ≥ 80 mg of oral furosemide daily, and have elevated natriuretic peptides. Patients were randomized 1:1 to treatment with a 1-h infusion of IV furosemide plus HSS (2.6–3.4% NaCl depending on plasmatic sodium levels) versus a 1-h infusion of IV furosemide at the same dose (125–250 mg, depending on basal loop diuretic dose). Clinical, laboratory, and imaging parameters were collected at baseline and after 7 days, and a telephone visit was planned after 30 days. The primary endpoint was 3-h diuresis after treatment started. Secondary endpoints included (a) 7-day changes in congestion data, (b) 7-day changes in kidney function and electrolytes, (c) 30-day clinical events (need of IV diuretic, HF hospitalization, cardiovascular mortality, all-cause mortality or HF-hospitalization). Results: A total of 167 participants [median age, 81 years; interquartile range (IQR), 73–87, 30.5% females] were randomized across 13 sites between December 2020 and March 2023. Half of the participants (n = 82) had an ejection fraction >50%. Most patients showed a high burden of comorbidities, with a median Charlson index of 3 (IQR: 2–4). Common co-morbidities included diabetes mellitus (41%, n = 69), atrial fibrillation (80%, n = 134), and chronic kidney disease (64%, n = 107). Patients exhibited a poor functional NYHA class (69% presenting NYHA III) and several signs of congestion. The mean composite congestion score was 4.3 (standard deviation: 1.7). Ninety per cent of the patients (n = 151) presented oedema and jugular engorgement, and 71% (n = 118) showed lung B lines assessed by ultrasound. Median inferior vena cava diameter was 23 mm, (IQR: 21–25), and plasmatic levels of N-terminal-pro-B-type natriuretic peptide (NTproBNP) and antigen carbohydrate 125 (CA125) were increased (median NT-proBNP 4969 pg/mL, IQR: 2508–9328; median CA125 46 U/L, IQR: 20–114). Conclusions: SALT-HF trial randomized 167 ambulatory patients with WHF and will determine whether an infusion of hypertonic saline therapy plus furosemide increases diuresis and improves decongestion compared to equivalent furosemide administration alone

Risk factors and rate of recurrence after Mohs surgery in basal cell and squamous cell carcinomas: a nationwide prospective cohort (REGESMOHS, Spanish Registry of Mohs Surgery)

Randomized studies to assess the efficacy of Mohs micrographic surgery in basal cell and squamous cell carcinomas are limited by methodological and ethical issues and a lack of long follow-up periods. This study presents the "real-life" results of a nationwide 7-years cohort on basal cell carcinoma and squamous cell carcinoma treated with Mohs micrographic surgery. A prospective cohort was conducted in 22 Spanish centres (from July 2013 to February 2020) and a multivariate analysis, including characteristics of patients, tumours, surgeries and follow-up, was performed. A total of 4,402 patients followed up for 12,111 patient-years for basal cell carcinoma, and 371 patients with 915 patient-years of follow-up for squamous cell carcinoma were recruited. Risk factors for recurrence included age, non-primary tumours and more stages or unfinished surgeries for both tumours, and immunosuppression for squamous cell carcinoma. Incidence rates of recurrence were 1.3 per 100 person-years for basal cell carcinoma (95% confidence interval 1.1-1.5) and 4.5 for squamous cell carcinoma (95% confidence interval 3.3-6.1), being constant over time (0-5 years). In conclusion, follow-up strategies should be equally intense for at least the first 5 years, with special attention paid to squamous cell carcinoma (especially in immunosuppressed patients), elderly patients, non-primary tumours, and those procedures requiring more stages, or unfinished surgeries
