RESUMO
RESUMEN Introducción: La insuficiencia cardíaca aguda es una problemática epidemiológica actual, en correlación con el incremento de la edad poblacional y la mayor sobrevida de los pacientes con enfermedades cardiovasculares. Objetivos: Evaluar el perfil clínico, las estrategias diagnósticas y terapéuticas y las complicaciones durante la internación y el seguimiento a 30 días del registro ARGEN-IC. Materiales y Métodos: Se efectuó un estudio prospectivo multicéntrico nacional, basado en los datos suministrados por 50 instituciones de salud (período: agosto 2018 a marzo 2019) referidos a pacientes con diagnóstico primario de insuficiencia cardíaca aguda, con un seguimiento de 12 meses. Resultados: Se incluyeron los datos de 909 pacientes aportados por 74 investigadores de 18 provincias. La media y el desvío estándar de la edad de los pacientes fue 72,2 (+-14) años y el 60,5% era de sexo masculino. Entre las características basales de esta cohorte, se destacaron las siguientes (prevalencia): diabetes (33%); IAM previo (17%); fibrilación auricular (31%); cobertura médica de prepagas (38%). Entre los factores desencadenantes, predominaron las causas desconocidas (28.5%), seguidas de las infecciosas (15,7%) y de transgresión alimentaria (13,5%). Se destaca la etiología isquémico-necrótica (26%), la presentación como congestión mixta (48%) y el grupo con fracción de eyección (Fey) deteriorada < o igual 40%. Las tasas de utilización de péptidos natriuréticos fueron cercanas al 50% y 25% al ingreso y egreso, respectivamente, y en el ecocardiograma se evaluó la funcion diastólica en un 77%, con alteracion significativa en el 46%. El 77,6% ingresó a unidad de cuidados críticos y la mediana de estadía hospitalaria global fue de 8 días, con una mortalidad global del 7,9%. El tratamiento farmacológico al egreso encontró en el grupo con Fey reducida: beta bloqueantes (BB), 78,7%; IECA, ARA II o ARNI, 70,9%; y antialdosterónicos, 56,3%. La derivación a rehabilitación cardiovascular abarcó el 17%. A 30 días se observó una tasa de reinternaciones del 16,7%; de mortalidad, del 5.5% (eventos combinados: 18%); y solamente el 47% había accedido a la consulta médica. Conclusiones: El registro ARGEN-IC abarca una población heterogénea, con una elevada edad media y alto número de comorbilidades. Las estrategias diagnósticas y terapéuticas demostraron estar sub-optimizada durante la hospitalización y los primeros 30 días, con escaso acceso al sistema de salud. La tasa global de eventos combinados intrahospitalarios y a 30 días continúa siendo elevada.
SUMMARY Introduction: Acute Heart Failure is currently an epidemiological problem, with a close correlation with the increase in the population age and the greater survival of patients with cardiovascular diseases. Objectives: Evaluate the clinical profile, the diagnostic and therapeutic strategies and the complications during hospitalization and the 12-month follow up of the ARGEN IC Registry. Materials and Methods: It's a prospective, multicenter, national Registry which included 50 health centers (August 2018-March 2019) and included patients with a confirmed diagnosis of acute heart failure with a 12-month follow-up. Results: A total of 909 patients were included, corresponding to 18 provinces and 73 active researchers. The mean age was 72.2 (SD 14) years, 60.5% of the patients were males. Baseline characteristics include a prevalence of diabetes of 33%, previous AMI 17%, and Atrial Fibrillation 31% and a predominant private security medical coverage (38%) Among the trigger factors of decompensation, 28.5% were associated with unknown causes, 15.7% infectious causes, and 13.5% with food transgression. The ischemic-necrotic etiology (26%), the presentation as mixed congestion (48%) and the impaired ejection fraction (EF) group stand out. 77.6% of the patients were admitted to the critical care unit, with a median overall hospital stay of 8 days and overall mortality of 7.9%. The pharmacological treatment at discharge, including the group with reduced EF: Beta Blockers (BB) 78.7%, ACEI, ARA II or ARNI 70.9% and anti aldosteronic 56.3% and the referral to cardiovascular rehabilitation in 17%. The 30-day follow-up showed a rehopitalization rate of 16.7%, mortality of 5.5% and combined events of 18%. Only 47% accessed the medical consultation. Conclusions: The ARGEN-IC Registry represents a heterogeneous population, with high middle ages and comorbidities. The diagnostic and therapeutic strategies are underutilized during hospitalization and in the first 30 days, with poor access to the health system. The overall combined rate of in-hospital events and at 30 days remains high.
RESUMO
OBJECTIVES: Patients with systemic lupus erythematosus (SLE) and primary Sjögren's syndrome (pSS) have increased IL-1ß levels. IL-1ß and other pro-inflammatory cytokines have a modulating activity on cardiac ion channels and have been associated with increased arrhythmic risk in rheumatoid arthritis patients. Likewise, adult patients with connective tissue diseases (CTDs) may have prolonged QTc intervals associated with the presence of anti-Ro/SSA antibodies. Our objective was to evaluate the presence of serum IL-1ß in subjects with CTDs, in relation to the presence of anti-Ro/SSA antibodies and QTc interval duration. METHODS: 12-lead electrocardiograms (ECG) were performed and blood was withdrawn, measuring electrolytes, IL-1ß anti-Ro/SSA antibodies by ELISA in 73 patients with CTDs. RESULTS: 55 patients were anti-Ro/SSA positive and 18 were anti-Ro/SSA negative. Patients with anti-Ro/SSA positive antibodies had a significantly greater median IL-1ß serum level: 7.29 (range: 0.17-17.3 pg/ml) compared to patients with anti-Ro/SSA negative antibodies whose median was: 1.67 (range 0.55-4.12 pg/ml) p<0.001. The mean QTc interval values obtained in both groups were not significantly different (417.7±23.1 vs. 414.7±21.2, p=0.63). The QTc interval was prolonged in 11 (20%) patients, who were all anti-Ro/SSA positive versus 0 (0 %) in anti-Ro/SSA negative patients p=0.05. Median IL-1ß levels were: 8.7 (range: 2.69-15.1 pg/ml) in patients with prolonged QTc interval versus median: 5.0 (range: 0.17-17.3 pg/ml) in those with normal QTc interval values (<440ms) p=0.006. CONCLUSIONS: IL-1ß is elevated in patients with CTDs that have both anti-Ro/SSA antibodies and prolonged QTc intervals.
