RESUMEN

BACKGROUND: Recent studies show Silent Myocardial Infarction (SMI) as a quite frequent event. However, regarding severe tertiary care patients that frequently present consequences of Coronary Artery Disease (CAD) and Left Ventricular Dysfunction (LVD), the occurrence of this manifestation is unexpected and its associated factors aren't clear in the literature. AIM: To compare clinical, laboratorial, ventricular and angiographic factors between silent and classical presentation of MI in patients with CAD and LVD. METHODS: Patients with multivessel CAD with over 70 % obstructive lesions and LVD with EF less than 35 % were evaluated for MASS VI trial and later included in the present study. The ventricular function and coronary assessment were measured by echocardiography and SYNTAX score, respectively. The population was stratified in a SMI group and Clinically Manifested Myocardial Infarction (CMMI) group based on MI presentation for a comparison of medical parameters. RESULTS: From 132 patients, 47 (35.6 %) were classified as SMI and 85 (64.4 %) as CMMI. No differences were observed between groups regarding age, sex, diabetes mellitus, SYNTAX score, or collateral circulation. Higher proportion of NYHA II classification, inferior wall MI and lower creatinine clearance were found in SMI group. After multivariate analysis, peripheral diabetic neuropathy (OR = 4.6 [1.1‒12.7] p = 0.032) and inferior wall MI (OR = 4.1 [1.5‒11.4] p = 0.007) were significantly associated with SMI. CONCLUSION: Peripheral diabetic neuropathy and inferior wall MI were associated with SMI presentation. Overall, associated factors tend to be similar comparing SMI and CMMI, but in the specific population of diabetic patients with chronic neuropathy a special care should be taken.

RESUMEN

INTRODUCTION: Pleural effusion (PE) is a common manifestation of acute decompensated heart failure (ADHF); however, its influence on the quality of life (QoL) is unknown. OBJECTIVES: To identify whether PE detected using thoracic ultrasound (TUS) is associated with poorer QoL in patients with ADHF and a reduced ejection fraction (≤40 %). METHODS: We conducted a prospective, longitudinal, descriptive, observational, single-center study at a university hospital in Mexico. We included participants with a reduced left ventricular ejection fraction who were admitted for ADHF. We performed TUS and the Minnesota Living with Heart Failure Questionnaire (MLHFQ) within the first 48 h of hospitalization. RESULTS: Forty patients with ADHF (30 males and 10 females; mean age, 51.24 ± 16.942 years) were included in this study. The participants were categorized into two groups: those with (n = 25, 62.5 %) or without (n = 15, 37.5 %) PE on TUS. We found a statistically significant association between the presence of PEs and a worse perception of QoL. The mean MLHFQ score in the group of patients with PEs was 40 points, compared to 12 points in the group without PEs (p < 0.001). Poorer QoL was associated with a higher quantity of pleural fluid, as evidenced by the greater number of intercostal spaces occupied by the PE (p < 0.001). CONCLUSIONS: Patients with ADHF and a reduced ejection fraction who present with PE have a worse perception of QoL than patients without PE.

RESUMEN

INTRODUCTION: Heart failure and type 2 diabetes mellitus are critical public health issues. OBJECTIVE: To characterize the risk factors for mortality in patients with heart failure and type 2 diabetes mellitus from a large registry in Colombia and to evaluate the potential effect modifications by type 2 diabetes mellitus over other risk factors. MATERIALS AND METHODS: Heart failure patients with and without type 2 diabetes mellitus enrolled in the Registro Colombiano de Falla Cardíaca (RECOLFACA) were included. RECOLFACA enrolled adult patients with heart failure diagnosis from 60 medical centers in Colombia during 2017-2019. The primary outcome was all-cause mortality. Survival analysis was performed using adjusted Cox proportional hazard models. RESULTS: A total of 2514 patients were included, and the prevalence of type 2 diabetes mellitus was 24.7% (n = 620). We found seven independent predictors of short-term mortality for the general cohort, chronic obstructive pulmonary disease, sinus rhythm, triple therapy, nitrates use, statins use, anemia, and hyperkalemia. In the type 2 diabetes mellitus group, only the left ventricle diastolic diameter was an independent mortality predictor (HR = 0.96; 95% CI: 0.93-0.98). There was no evidence of effect modification by type 2 diabetes mellitus on the relationship between any independent predictors and all-cause mortality. However, a significant effect modification by type 2 diabetes mellitus between smoking and mortality was observed. CONCLUSIONS: Patients with type 2 diabetes mellitus had higher mortality risk. Our results also suggest that type 2 diabetes mellitus diagnosis does not modify the effect of the independent risk factors for mortality in heart failure evaluated. However, type 2 diabetes mellitus significantly modify the risk relation between mortality and smoking in patients with heart failure.


Introducción. La insuficiencia cardíaca y la diabetes mellitus de tipo 2 son problemas críticos de salud pública. Objetivo. Caracterizar los factores de riesgo de mortalidad en pacientes con insuficiencia cardíaca y la diabetes mellitus de tipo 2 de un registro grande en Colombia y evaluar las posibles modificaciones del efecto de la diabetes mellitus de tipo 2 sobre otros factores de riesgo. Materiales y métodos. Se incluyeron pacientes con insuficiencia cardíaca con y sin diabetes mellitus de tipo 2, inscritos en el Registro Colombiano de Insuficiencia Cardíaca (RECOLFACA). RECOLFACA incorporó pacientes adultos con diagnóstico de insuficiencia cardíaca de 60 centros médicos de Colombia durante 2017-2019. El resultado primario fue la mortalidad por todas las causas. El análisis de supervivencia se realizó utilizando modelos ajustados de riesgos proporcionales de Cox. Resultados. Se incluyeron 2.514 pacientes, la prevalencia de diabetes mellitus de tipo 2 fue del 24,7 % (n = 620). Encontramos siete predictores independientes de mortalidad a corto plazo para la enfermedad pulmonar obstructiva crónica del grupo sin diabetes mellitus de tipo 2, el ritmo sinusal, la terapia triple, el uso de nitratos, el uso de estatinas, la anemia y la hiperpotasemia. En el grupo de diabetes mellitus de tipo 2, solo el diámetro diastólico del ventrículo izquierdo fue un predictor de mortalidad independiente (HR = 0,96; IC95 %: 0,93 - 0,98). No hubo evidencia de modificación del efecto de la diabetes mellitus de tipo 2 sobre la relación entre ningún predictor independiente y la mortalidad por todas las causas. Sin embargo, se observó una modificación significativa del efecto de la diabetes mellitus de tipo 2 entre el tabaquismo y la mortalidad. Conclusiones. Los pacientes con diabetes mellitus de tipo 2 tuvieron mayor riesgo de mortalidad. Los resultados también sugieren que el diagnóstico de diabetes mellitus de tipo 2 no modifica el efecto de los factores de riesgo independientes de mortalidad en IC evaluados. Sin embargo, la diabetes mellitus de tipo 2 modifica significativamente la relación de riesgo entre mortalidad y tabaquismo en pacientes con insuficiencia cardíaca, posiblemente debido a un efecto sinérgico negativo que resulta en lesión vascular.

RESUMEN

Point-of-care ultrasound (POCUS) is an important tool for clinical diagnosis and decision-making in critical and non-critical scenarios. Dyspnea, chest pain, and shock are conditions susceptible to evaluation with ultrasound considering diagnostic accuracy and clinical impact already proven. There is scarce evidence in diagnosis agreement using ultrasound as an extension of physical examination. We aimed to evaluate ED patients in whom POCUS was performed, to analyze agreement between clinical initial diagnosis using ultrasound images and final diagnosis. Furthermore, we analyze failed diagnosis, inconclusive POCUS exams, and discuss details. A cross-sectional analytical study was conducted on adults who visited the emergency department with any of these three chief complaints: dyspnea, chest pain, and shock. All were evaluated with ultrasound at admission. Agreement between initial diagnosis using POCUS and final definite diagnosis was calculated. Failed diagnosis and inconclusive exams were analyzed. A total of 209 patients were analyzed. Populations: mostly males, mean age 64 years old, hypertensive. Agreement on patients with dyspnea and suspicion of acute decompensated heart failure was 0.98; agreement on chest pain suspicion of non-ST acute coronary syndrome was 0.96; agreement on type of shock was 0.90. Among the population, 12 patients had an inconclusive POCUS exam, and 16 patients had a failed diagnosis. The use of POCUS in the emergency department shows almost perfect agreement when compared with the final diagnosis in individuals experiencing acutely decompensated heart failure, acute coronary syndrome, and shock. Prospective studies are needed to evaluate the impact of this tool on mortality and prognosis when there are diagnostic errors.

RESUMEN

BACKGROUND: The optimal treatment of atrial fibrillation (AF) in patients with heart failure with reduced ejection fraction (HFrEF) remains unsettled. OBJECTIVE: The purpose of this study was to assess the efficacy of catheter ablation (CA) and medical therapy compared to medical therapy alone in patients with AF and HFrEF. METHODS: We performed a systematic review of randomized controlled trials (RCTs) comparing CA with guideline-directed medical therapy for AF in patients with HFrEF (left ventricular ejection fraction [LVEF] ≤ 40%). We systematically searched PubMed, Embase, and Cochrane for eligible trials. A random effects model was used to calculate the risk ratios (RRs) and mean differences (MDs), with 95% confidence intervals (CIs). RESULTS: Six RCTs comprising 1055 patients were included, of whom 530 (50.2%) were randomized to CA. Compared with medical therapy, CA was associated with a significant reduction in heart failure (HF) hospitalization (RR 0.57; 95% CI 0.45-0.72; P < .01), cardiovascular mortality (RR 0.46; 95% CI 0.31-0.70; P < .01), all-cause mortality (RR 0.53; 95% CI 0.36-0.78; P < .01), and AF burden (MD -29.8%; 95% CI -43.73% to -15.90%; P < .01). Also, there was a significant improvement in LVEF (MD 3.8%; 95% CI 1.6%-6.0%; P < .01) and quality of life (Minnesota Living with Heart Failure Questionnaire; MD -4.92 points; 95% CI -8.61 to -1.22 points; P < .01) in the ablation group. CONCLUSION: In this meta-analysis of RCTs of patients with AF and HFrEF, CA was associated with a reduction in HF hospitalization, cardiovascular mortality, and all-cause mortality as well as a significant improvement in LVEF and quality of life.

RESUMEN

BACKGROUND: Heart failure (HF) is a chronic condition with symptoms linked to worse quality of life. Malnutrition and sarcopenia are conditions frequently found in patients with HF. This study aims to evaluate the association between isolated or combined malnutrition and sarcopenia and quality of life in outpatients with HF. METHODS: This is a cross-sectional study with a sample of outpatients with HF aged ≥18 years. Malnutrition was assessed according to the criteria of the Global Leadership Initiative on Malnutrition, and sarcopenia was evaluated by the European Working Group on Sarcopenia in Older People. Quality of life was assessed using the Minnesota Living with HF questionnaire (MLHFQ). Clinical and sociodemographic data were collected. RESULTS: One hundred and fifty-one patients were included in this study, with a median (interquartile range) age of 58 (48-65) years, 58.9% were adults, and 68.9% were male. A total of 29.5% of the patients were malnourished, and 28.5% and 2.6% were identified with probable sarcopenia and sarcopenia, respectively. Of the total, 15.9% of patients were identified with both conditions. Sarcopenia was associated with higher odds of increase in the MLHFQ total score, indicating worse quality of life (odds ratio [OR] = 3.61; 95% CI, 1.65-7.89). The same was found in the presence of two conditions (OR 3.97; 95% CI, 1.32-11.54), whereas isolated malnutrition was not related to life quality (OR = 1.62; 95% CI, 0.73-3.60). CONCLUSION: The presence of malnutrition and sarcopenia simultaneously were associated with worse quality of life scores when compared with these isolated conditions.

RESUMEN

BACKGROUND: The benefit of catheter ablation for atrial fibrillation (AF) in patients with heart failure with preserved ejection fraction (HFpEF) remains uncertain. OBJECTIVE: We performed a systematic review and meta-analysis to compare catheter ablation and medical therapy (antiarrhythmics for rhythm or rate control) in patients with AF and HFpEF. METHODS: We searched PubMed, Embase, and Cochrane Central Register of Controlled Trials. Outcomes were the composite end points of death or heart failure (HF) hospitalization, all-cause death, cardiovascular death, all-cause rehospitalization, and HF hospitalization. Statistical analysis was performed using R statistical software, version 4.3.2 (R Foundation for Statistical Computing). Heterogeneity was assessed with I2 statistics. RESULTS: We included 20,257 patients from 8 studies. Of those, 3 were derived from RCTs, either through post hoc analysis or subgroup analysis, and 5 were observational studies. The median follow-up ranged from 24.6 to 61.2 months. Compared with medical therapy, catheter ablation was associated with a statistically significant lower risk of death or HF hospitalization (hazard ratio [HR] 0.62; 95% confidence interval [CI] 0.47-0.83; P = .001; I2 = 66%), all-cause death (HR 0.68; 95% CI 0.46-0.99; P = .047; I2 = 61%), cardiovascular death (HR 0.42; 95% CI 0.21-0.84; P = .014; I2 = 22%), and HF hospitalization (HR 0.43; 95% CI 0.23-0.82; P = .011; I2 = 87%). CONCLUSION: In this meta-analysis, catheter ablation was associated with a lower risk of all-cause death, cardiovascular death, HF hospitalization, and all-cause rehospitalization in comparison to medical therapy in patients with AF and HFpEF.

RESUMEN

PURPOSE OF REVIEW: Chronic obstructive pulmonary disease (COPD) is common in heart failure (HF), and it has a significant impact on the prognosis and quality of life of patients. Additionally, COPD is independently associated with lower adherence to first-line HF therapies. In this review, we outline the challenges of identifying and managing HF with preserved (HFpEF) and reduced (HFrEF) ejection fraction with coexisting COPD. RECENT FINDINGS: Spirometry is necessary for COPD diagnosis and prognosis but is underused in HF. Therefore, misdiagnosis is a concern. Also, disease-modifying drugs for HF and COPD are usually safe but underprescribed when HF and COPD coexist. Patients with HF-COPD are poorly enrolled in clinical trials. Guidelines recommend that HF treatment should be offered regardless of COPD presence, but modern registries show that undertreatment persists. Treatment gaps could be attenuated by ensuring an accurate and earlier COPD diagnosis in patients with HF, clarifying the concerns related to pharmacotherapy safety, and increasing the use of non-pharmacologic treatments. Acknowledging the uncertainties, this review aims to provide key clinical resources to support better physician-patient co-decision-making and improve collaboration between health professionals.

RESUMEN

BACKGROUND: Aortic stenosis (AS) is currently the most common valvular disease, with an estimated prevalence of over 4% in octogenarians. OBJECTIVE: To describe the prevalence of moderate-severe aortic stenosis (AS) in patients with wild type transthyretin amyloidosis (ATTRwt). Also, describe the clinical features, echocardiographic characteristics and clinical evolution. METHOD: Retrospective cohort of patients with diagnosis of ATTRwt, belonging to Hospital Italiano de Buenos Aires Institutional Amyloidosis Registry, from 30/11/2007 to 31/05/2021. Patients follow up was carried out through the institution clinical history. The prevalence of moderate-severe AE was estimated and presented as a percentage with its 95% confidence interval (95% CI). The characteristics were compared by groups according to whether or not they had moderate-severe AS. RESULTS: 104 patients with ATTRwt were included. Median follow up was 476 days [interquartile range: 192-749]. Moderate-severe AS prevalence at the ATTRwt time of diagnosis was 10.5% (n = 11; 95% CI: 5-18%). The median age of patients with AS moderate-severe at the time of diagnosis of ATTRwt was 86 years [78-91] and the male sex predominated (82%). Most of the patients had a history of heart failure (n = 8) and atrial fibrillation (n = 8) prior to the diagnosis of ATTRwt. Most of the patients were subclassified as low flow low gradient severe AS group (n = 7). Four patients underwent some intervention on the aortic valve. During follow-up, 5 patients (46%) were hospitalized for decompensated heart failure and 4 (36%) died. CONCLUSIONS: In our cohort, the coexistence of both pathologies had a similar prevalence as reported in the international literature. It was an elderly population with a high percentage of atrial fibrillation and history of heart failure. Most of the patients presented with severe AS with low flow low gradient.


ANTECEDENTES: La estenosis aórtica (EA) es actualmente la enfermedad valvular más frecuente, con una prevalencia estimada de más del 4 % en octogenarios. OBJETIVO: Describir la prevalencia de estenosis aórtica (EA) moderada-grave en pacientes con amiloidosis por transtiretina wild type (ATTRwt). Además, describir las características clínicas, ecocardiográficas y la evolución en este grupo de pacientes. MÉTODO: Estudio de cohorte retrospectiva de pacientes con diagnóstico de ATTRwt, pertenecientes al Registro Institucional de Amiloidosis del Hospital Italiano de Buenos Aires, en el periodo del 30/11/2007 al 31/05/2021. El seguimiento de los pacientes se realizó a través de la historia clínica electrónica de la institución. Se estimó la prevalencia de EA moderada-grave, que se presenta como porcentaje con su intervalo de confianza del 95% (IC 95%). Se compararon las características por grupos según tuvieran o no EA moderada-grave. RESULTADOS: Se incluyeron 104 pacientes con diagnóstico de ATTRwt. La mediana de seguimiento fue de 476 días [rango intercuartílico: 192-749]. La prevalencia de EA moderada-grave al momento del diagnóstico de ATTRwt fue del 10.5% (n = 11; IC95%: 5-18%). La mediana de edad de los pacientes con EA fue de 86 años [78-91] y predominó el sexo masculino (81.8%). La mayoría de los pacientes tenían el antecedente de insuficiencia cardiaca (n = 8) y fibrilación auricular (n = 8). Predominaron los pacientes con EA grave de bajo flujo y bajo gradiente (n = 7). Cuatro pacientes fueron sometidos a alguna intervención en la válvula aórtica. Durante el seguimiento, 5 pacientes (46%) tuvieron internaciones por insuficiencia cardiaca descompensada y 4 (36%) fallecieron. CONCLUSIONES: En nuestra cohorte, la coexistencia de ambas patologías tuvo una prevalencia similar a la reportada en la literatura internacional. Se trató de una población añosa con alto porcentaje de fibrilación auricular y antecedente de insuficiencia cardiaca. La mayoría presentaron EA grave de bajo flujo y bajo gradiente.

RESUMEN

Sarcopenia, a clinical syndrome primarily associated with reduced muscle mass in the elderly, has a negative impact on quality of life and survival. It can occur secondarily to other diseases such as heart failure (HF), a complex clinical syndrome with high morbidity and mortality. The simultaneous occurrence of these two conditions can worsen the prognosis of their carriers, especially in the most severe cases of HF, as in patients with reduced left ventricular ejection fraction (LVEF). However, due to the heterogeneous diagnostic criteria for sarcopenia, estimates of its prevalence present a wide variation, leading to new criteria having been recently proposed for its diagnosis, emphasizing muscle strength and function rather than skeletal muscle mass. The primary objective of this study is to evaluate the prevalence of sarcopenia and/or dynapenia in individuals with HF with reduced LVEF according to the most recent criteria, and compare the gene and protein expression of those patients with and without sarcopenia. The secondary objectives are to evaluate the association of sarcopenia and/or dynapenia with the risk of clinical events and death, quality of life, cardiorespiratory capacity, ventilatory efficiency, and respiratory muscle strength. The participants will answer questionnaires to evaluate sarcopenia and quality of life, and will undergo the following tests: handgrip strength, gait speed, dual-energy X-ray absorptiometry, respiratory muscle strength, cardiopulmonary exercise, as well as genomic and proteomic analysis, and dosage of N-terminal pro-B-type natriuretic peptide and growth differentiation factor-15. An association between sarcopenia and/or dynapenia with unfavorable clinical evolution is expected to be found, in addition to reduced quality of life, cardiorespiratory capacity, ventilatory efficiency, and respiratory muscle strength.

RESUMEN

PURPOSE: Exercise intolerance and dyspnoea are clinical symptoms in both heart failure (HF) reduced ejection fraction (HFrEF) and chronic obstructive pulmonary disease (COPD), which are suggested to be associated with musculoskeletal dysfunction. We tested the hypothesis that HFrEF + COPD patients would present lower muscle strength and greater fatigue compared to compared to the COPD group. METHODS: We included 25 patients with HFrEF + COPD (100% male, age 67.8 ± 6.9) and 25 patients with COPD alone (100% male, age 66.1 ± 9.1). In both groups, COPD severity was determined as moderate-to-severe according to the GOLD classification (FEV1/FVC < 0.7 and predicted post-bronchodilator FEV1 between 30%-80%). Knee flexor-extensor muscle performance (torque, work, power and fatigue) were measured by isokinetic dynamometry in age and sex-matched patients with HFrEF + COPD and COPD alone; Functional capacity was assessed by the cardiopulmonary exercise test, the 6-min walk test (6MWT) and the four-minute step test. RESULTS: The COPD group exhibited reduced lung function compared to the HFrEF + COPD group, as evidenced by lower FEV1/FVC (58.0 ± 4.0 vs. 65.5 ± 13.9; p < 0.0001, respectively) and FEV1 (51.3 ± 17.0 vs. 62.5 ± 17.4; p = 0.026, respectively) values. Regarding musculoskeletal function, the HFrEF + COPD group showed a knee flexor muscles impairment, however this fact was not observed in the knee extensors muscles. Power peak of the knee flexor corrected by muscle mass was significantly correlated with the 6MWT (r = 0.40; p < 0.05), number of steps (r = 0.30; p < 0.05) and work ratepeak (r = 0.40; p < 0.05) in the HFrEF + COPD and COPD groups. CONCLUSION: The presence of HFrEF in patients with COPD worsens muscular weakness when compared to isolated COPD.

RESUMEN

BACKGROUND: In patients with heart failure and reduced ejection fraction, sleep-disordered breathing, comprising obstructive sleep apnoea (OSA) and central sleep apnoea (CSA), is associated with increased morbidity, mortality, and sleep disruption. We hypothesised that treating sleep-disordered breathing with a peak-flow triggered adaptive servo-ventilation (ASV) device would improve cardiovascular outcomes in patients with heart failure and reduced ejection fraction. METHODS: We conducted a multicentre, multinational, parallel-group, open-label, phase 3 randomised controlled trial of peak-flow triggered ASV in patients aged 18 years or older with heart failure and reduced ejection fraction (left ventricular ejection fraction ≤45%) who were stabilised on optimal medical therapy with co-existing sleep-disordered breathing (apnoea-hypopnoea index [AHI] ≥15 events/h of sleep), with concealed allocation and blinded outcome assessments. The trial was carried out at 49 hospitals in nine countries. Sleep-disordered breathing was stratified into predominantly OSA with an Epworth Sleepiness Scale score of 10 or lower or predominantly CSA. Participants were randomly assigned to standard optimal treatment alone or standard optimal treatment with the addition of ASV (1:1), stratified by study site and sleep apnoea type (ie, CSA or OSA), with permuted blocks of sizes 4 and 6 in random order. Clinical evaluations were performed and Minnesota Living with Heart Failure Questionnaire, Epworth Sleepiness Scale, and New York Heart Association class were assessed at months 1, 3, and 6 following randomisation and every 6 months thereafter to a maximum of 5 years. The primary endpoint was the cumulative incidence of the composite of all-cause mortality, first admission to hospital for a cardiovascular reason, new onset atrial fibrillation or flutter, and delivery of an appropriate cardioverter-defibrillator shock. All-cause mortality was a secondary endpoint. Analysis for the primary outcome was done in the intention-to-treat population. This trial is registered with ClinicalTrials.gov (NCT01128816) and the International Standard Randomised Controlled Trial Number Register (ISRCTN67500535), and the trial is complete. FINDINGS: The first and last enrolments were Sept 22, 2010, and March 20, 2021. Enrolments terminated prematurely due to COVID-19-related restrictions. 1127 patients were screened, of whom 731 (65%) patients were randomly assigned to receive standard care (n=375; mean AHI 42·8 events per h of sleep [SD 20·9]) or standard care plus ASV (n=356; 43·3 events per h of sleep [20·5]). Follow-up of all patients ended at the latest on June 15, 2021, when the trial was terminated prematurely due to a recall of the ASV device due to potential disintegration of the motor sound-abatement material. Over the course of the trial, 41 (6%) of participants withdrew consent and 34 (5%) were lost to follow-up. In the ASV group, the mean AHI decreased to 2·8-3·7 events per h over the course of the trial, with associated improvements in sleep quality assessed 1 month following randomisation. Over a mean follow-up period of 3·6 years (SD 1·6), ASV had no effect on the primary composite outcome (180 events in the control group vs 166 in the ASV group; hazard ratio [HR] 0·95, 95% CI 0·77-1·18; p=0·67) or the secondary endpoint of all-cause mortality (88 deaths in the control group vs. 76 in the ASV group; 0·89, 0·66-1·21; p=0·47). For patients with OSA, the HR for all-cause mortality was 1·00 (0·68-1·46; p=0·98) and for CSA was 0·74 (0·44-1·23; p=0·25). No safety issue related to ASV use was identified. INTERPRETATION: In patients with heart failure and reduced ejection fraction and sleep-disordered breathing, ASV had no effect on the primary composite outcome or mortality but eliminated sleep-disordered breathing safely.

RESUMEN

INTRODUCTION: Transthyretin amyloid cardiomyopathy (ATTR-CM) is an underdiagnosed cause of AHF that benefits from a specific approach. The aim was to determine the prevalence of ATTR-CM among patients hospitalized for AHF. METHODS: A prospective study was conducted on consecutive patients aged 60 or older admitted for acute AHF without cardiogenic shock. RESULTS: The study included 103 patients, a total of 16 patients (15.5 %) were compatible with ATTR-CM. The ATTR-CM group showed a higher septal wall thickness (18.1 mm vs. 11.8 mm; P = 0.001), lower systolic excursion of the tricuspid annular plane (15 mm vs. 18.3 mm, P = 0.014), and S wave of the right ventricle (8 cm/s vs. 9.2 cm/s P=0.032). CONCLUSION: ATTR-CM is an underdiagnosed condition, there are some variables associated with its diagnosis. The coexistence with other comorbidities causing AHF, highlights the importance of considering screening for this cardiomyopathy in adults hospitalized for AHF.

RESUMEN

INTRODUCTION: In cardiorenal syndrome type 1 (CRS1), vascular congestion is central to the pathophysiology of heart failure and thus a key target for management. The venous evaluation by ultrasound (VExUS) system could guide decongestion effectively and thereby improve outcomes. METHODS: In this randomized clinical trial, patients with CRS1 (i.e., increase in creatinine ≥0.3 mg/dL) were randomized to guide decongestion with VExUS compared to usual clinical evaluation. The primary endpoint was to assess kidney function recovery (KFR), and the key secondary endpoint was decongestion evaluated by physical examination and changes in brain natriuretic peptide (BNP) and CA-125. Exploratory endpoints included days of hospitalization and mortality. RESULTS: From March 2022 to February 2023, a total of 140 patients were randomized 1:1 (70 in the VExUS and 70 in the control group). KFR was not statistically different between groups. However, VExUS improved more than twice the odds to achieve decongestion (odds ratio [OR]: 2.6, 95% CI: 1.9-3.0, p = 0.01) and the odds to reach a decrease of BNP >30% (OR: 2.4, 95% CI: 1.3-4.1, p = 0.01). The survival at 90 days, recongestion, and CA-125 were similar between groups. CONCLUSION: In patients with CRS1, we observed that VExUS-guided decongestion did not improve the probability of KFR but improved the odds to achieve decongestion.

RESUMEN

La congestión en pacientes con insuficiencia cardíaca representa una manifestación de diversos procesos estructurales y funcionales cardiovasculares, asociada a alta morbimortalidad y reducción de calidad de vida, se considera la principal causa de ingreso a hospitalización y reingreso por insuficiencia cardíaca. Durante las últimas décadas, se ha logrado un mejor entendimiento de los diversos eventos fisiopatológicos desencadenantes, lo cual ha mejorado su pronóstico, diagnóstico y tratamiento. Por estos constantes avances, es necesaria su frecuente revisión y análisis. La atención del paciente con insuficiencia cardíaca y episodios de congestión es compleja y crucial. Su abordaje inicia con el reconocimiento temprano de las manifestaciones clínicas, uso de métodos no invasivos diagnósticos, delimitación del perfil de congestión; consecuentemente, es necesario brindar un manejo oportuno, intensivo y eficaz que contemple el empleo temprano de diuréticos intravenosos, la evaluación de metas de descongestión y, en casos específicos, terapia diurética combinada e incluso medicamentos vasoactivos o ultrafiltración continua.


Congestion in patients with heart failure represents a manifestation of various cardiovascular structural and functional processes, associated with high morbidity and mortality and reduced quality of life, being considered the main cause of hospitalization and readmission due to heart failure. During the last decades, a better understanding of the various triggering pathophysiological events has been achieved, modifying their prognosis, diagnosis, and treatment. Due to these constant advances, its frequent review and analysis is necessary. The care of patients with heart failure and episodes of congestion is complex and crucial. Its approach begins with early recognition of clinical manifestations, use of non-invasive diagnostic methods, delimitation of the congestion profile; followed by timely, intensive, and effective management that contemplates the early use of intravenous diuretics, evaluation of decongestion goals and, in specific cases, combined diuretic therapy, and even vasoactive medications or continuous ultrafiltration.

RESUMEN

The complex, heterogeneous, and dynamic interaction between the interstitial and intravascular fluid compartments is one of the main reasons for the wide variability in the distribution and severity of congestion among patients with acute heart failure. The "hemodynamic congestion" often goes undetected clinically; as opposed to "clinical congestion", which occurs later and is evidenced by dyspnea and orthopnea, rales, peripheral edema, and jugular venous distension. Clinical signs, chest X-ray, brain natriuretic peptide (BNP) or N-terminal-proBNP (NT-proBNP), central venous pressure (CVP), echocardiogram, inferior vena cava (IVC) diameter, and pulmonary wedge pressure are the most commonly used elements to assess congestion. Other alternatives are pulmonary and visceral ultrasound (VEXUS), CA 125 and other markers, and recently, the CardioMems system.


La interacción compleja, heterogénea y dinámica entre los compartimentos de líquido intersticial e intravascular es una de las principales razones que explican la amplia variabilidad en la distribución y gravedad de la congestión entre los pacientes con insuficiencia cardíaca descompensada. La "congestión hemodinámica" suele pasar desapercibida clínicamente; en oposición a la "congestión clínica", que ocurre más tarde y se evidencia por disnea y ortopnea, estertores pulmonares, edema periférico y distensión venosa yugular. Los signos clínicos, la radiografía de tórax, el péptido natriurético cerebral (brain natriuretic peptide o BNP) o la porción terminal N del pro BNP (NT-proBNP), la presión venosa central (PVC), el ecocardiograma, el diámetro de la vena cava inferior (VCI) y la presión de enclavamiento pulmonar son los elementos más utilizados para evaluar la congestión. Otras alternativas son el ultrasonido pulmonar y visceral (VEXUS), el CA 125 y otros marcadores y, recientemente, el sistema CardioMems.

RESUMEN

BACKGROUND: The trabecular bone score (TBS) indirectly estimates bone quality and predicts low-impact fractures independently of bone mineral density (BMD). However, there is still a paucity of data linking bone and heart diseases, mainly with gaps in the TBS analysis. METHODS: In this cross-sectional study, we evaluated TBS, BMD, and fractures in patients with heart failure with reduced ejection fraction (HFrEF) and in sex-, BMI- and age-matched controls, and we assessed the fracture probability using the FRAX tool, considering active search for fractures by vertebral fracture assessment (VFA) and the adjustment for the TBS. RESULTS: TBS values were 1.296 ± 0.14 in 85 patients (43.5% women; age 65 ± 13 years) and 1.320 ± 0.11 in 142 controls (P = 0.07), being reduced (< 1.31) in 51.8% and 46.1% of them, respectively (P = 0.12). TBS was lower in patients than in the controls when BMD was normal (P = 0.04) and when the BMI was 15-37 kg/m2 (P = 0.03). Age (odds ratio [OR] 1.05; P = 0.026), albumin (OR 0.12; P = 0.046), statin use (OR 0.27; P = 0.03), and energy intake (OR 1.03; P = 0.014) were associated with reduced TBS. Fractures on VFA occurred in 42.4% of the patients, and VFA and TBS adjustment increased the fracture risk by 16%-23%. CONCLUSION: Patients with HFrEF had poor bone quality, with a better discriminating impact of the TBS assessment when BMD was normal, and BMI was suitable for densitometric analysis. Variables related to the prognosis, severity, and treatment of HFrEF were associated with reduced TBS. VFA and TBS adjustment increased fracture risk.

RESUMEN

BACKGROUND/INTRODUCTION: Heart failure patients with reduced ejection fraction are at high risk for ventricular arrhythmias and sudden cardiac death. Ivabradine, a specific inhibitor of the If current in the sinoatrial node, provides heart rate reduction in sinus rhythm and angina control in chronic coronary syndromes. OBJECTIVE: The effect of ivabradine on ventricular arrhythmias in heart failure patients with reduced ejection fraction patients has not been fully elucidated. The aim of this study was to investigate the effect of ivabradine use on life-threatening arrhythmias and long-term mortality in heart failure patients with reduced ejection fraction patients. METHODS: In this retrospective study, 1,639 patients with heart failure patients with reduced ejection fraction were included. Patients were divided into two groups: ivabradine users and nonusers. Patients presenting with ventricular tachycardia, the presence of ventricular extrasystole, and ventricular tachycardia in 24-h rhythm monitoring, appropriate implantable cardioverter-defibrillator shocks, and long-term mortality outcomes were evaluated according to ivabradine use. RESULTS: After adjustment for all possible variables, admission with ventricular tachycardia was three times higher in ivabradine nonusers (95% confidence interval 1.5-10.2). The presence of premature ventricular contractions and ventricular tachycardias in 24-h rhythm Holter monitoring was notably higher in ivabradine nonusers. According to the adjusted model for all variables, 4.1 times more appropriate implantable cardioverter-defibrillator shocks were observed in the ivabradine nonusers than the users (95%CI 1.8-9.6). Long-term mortality did not differ between these groups after adjustment for all covariates. CONCLUSION: The use of ivabradine reduced the appropriate implantable cardioverter-defibrillator discharge in heart failure patients with reduced ejection fraction patients. Ivabradine has potential in the treatment of ventricular arrhythmias in heart failure patients with reduced ejection fraction patients.

RESUMEN

•The study investigated the prevalence of certain comorbidities in patients with Chagas megaoesophagus compared to those without the condition, aiming to determine whether it serves as a protective or risk factor. •In the general group (546 patients), the three most prevalent comorbidities were hypertension (44.3%), dyslipidaemia (17.8%), and heart failure (15.2%). •In the older group (248 patients), similar to that in the general group, the most prevalent comorbidities were hypertension, dyslipidaemia, and heart failure. •The lower prevalence of diabetes mellitus and Alzheimer's disease in the patients with Chagas megaoesophagus suggests the association of enteric nervous system denervation and requires further investigation. Objective - This study aimed to evaluate the prevalence of some epidemiologically important comorbidities in patients with Chagas megaoesophagus in relation to the population without megaoesophagus, and whether this condition would be a protective or a risk factor for the conditions analysed. Methods - This observational descriptive study collected data from the medical records of patients with a previous diagnosis of megaoesophagus (timing: from 2005 to 2020). The patients were divided by age into a general (all ages) and an older group (aged 60 years or more). Associations were searched for four main areas/systems/involvements: cardiovascular, respiratory, endocrine and neurological. Results - The general group included 546 patients and the older group included 248 patients. As for the prevalence of comorbidities in the general group, the three most prevalent diseases were hypertension, with 44.3% (CI95%: 40.21-48.51%); dyslipidaemia, with 17.8% (CI95%: 14.79-21.19%); and heart failure, with 15.2% (CI95%: 12.43-18.45%). Similar to that in the general group, the most prevalent comorbidities in the group of older patients were hypertension, dyslipidaemia, and heart failure. Conclusion - Systemic arterial hypertension, dyslipidaemia, and heart failure were the most prevalent comorbidities in this population. The lower prevalence of diabetes mellitus and Alzheimer's disease suggests the association of enteric nervous system denervation and requires further investigation.
