Esquistossomose e o Coração - Em Nome das Doenças Tropicais Negligenciadas e Outras Doenças Infecciosas que Afetam o Coração (Projeto NET-Heart) / Schistosomiasis & Heart - On Behalf of the Neglected Tropical Diseases and other Infectious Diseases affecting the Heart (the NET-Heart Project)

Resumo Fundamento A esquistossomose é uma doença tropical negligenciada que pode levar a complicações cardiovasculares. No entanto, o envolvimento cardiovascular na esquistossomose ainda precisa ser totalmente elucidado, devido ao número limitado de casos e ausência de evidência confiável, uma vez que a doença ocorre tipicamente em locais sem infraestrutura adequada para uma coleta de dados robusta. Objetivo Esta revisão sistemática teve como objetivo avaliar as implicações cardiovasculares da esquistossomose, incluindo no diagnóstico e tratamento, e propor um algoritmo para rastrear as manifestações cardiovasculares. Métodos Foi realizada uma revisão sistemática nos bancos de dados MEDLINE/PubMed e LILACS, com busca por artigos sobre o comprometimento cardiovascular na esquistossomose. Resultados Trinta e três artigos foram considerados para esta revisão: seis artigos de revisão, uma revisão sistemática, um ensaio clínico, 14 estudos observacionais, sete relatos de casos, e quatro séries de casos. O comprometimento cardiovascular inclui um amplo espectro de condições clínicas, tais como isquemia do miocárdio, disfunção ventricular, miocardite, hipertensão arterial pulmonar, e pericardite. Conclusões As complicações cardíacas da esquistossomose podem causar incapacidade em longo prazo e morte. O monitoramento clínico, exame físico, eletrocardiograma precoce, e ecocardiograma devem ser considerados como medidas chave para detectar o envolvimento cardiovascular. Dada a ausência de um tratamento eficaz das complicações, são necessários saneamento e educação nas áreas endêmicas para a eliminação desse problema de saúde mundial.

Abstract Background Schistosomiasis is a Neglected Tropical Disease which may lead to cardiovascular (CV) complications. However, the CV involvement in schistosomiasis has yet to be fully elucidated due to the limited number of cases and lack of reliable evidence, as schistosomiasis typically occurs in locations without adequate infrastructure for robust data collection. Objective This systematic review aims to assess cardiovascular implications of schistosomiasis, including in the diagnosis and treatment, and propose an algorithm for screening of CV manifestations. Methods A systematic review was performed in the MEDLINE/PubMed and LILACS databases of articles on the CV involvement in schistosomiasis. Results Thirty-three records were considered for this review: six review articles, one systematic review, one clinical trial, 14 observational studies, seven case reports, and four cases series. CV involvement includes a wide spectrum of clinical conditions, such as myocardial ischemia, ventricular dysfunction, myocarditis, pulmonary arterial hypertension, and pericarditis. Conclusions Cardiac complications of schistosomiasis may cause long-term disability and death. Clinical monitoring, physical examination, early electrocardiogram, and echocardiogram should be considered as key measures to detect CV involvement. Due to the lack of effective treatment of complications, sanitation and education in endemic areas are necessary for the elimination of this global health problem.

Enfermedades tropicales desatendidas y su impacto sobre la salud cardiovascular (The NET-heart project) / Neglected tropical diseases and their impact on cardiovascular health. (The NET-Heart Project)

Resumen Las enfermedades tropicales desatendidas (ETD) constituyen un conjunto de afecciones altamente prevalentes en regiones tropicales y subtropicales, asociadas a pobreza y subdesarrollo. Constituyen una verdadera crisis sanitaria, incapacitando y llevando a la muerte a millones de personas anualmente. Esto se ve potenciado por las dificultades socioeconómicas que cursan estos países, mayormente en vías de desa rrollo, lo cual repercute en la calidad de la asistencia sanitaria que pueden proveer a la población. La morbilidad de estas enfermedades se explica por la amplia afectación orgánica que generan. El aparato cardiovascular resulta particularmente afectado, lo que explica en gran medida la morbimortalidad de las ETD. En el presente artículo se revisan los aspectos fundamentales de un proyecto llevado a cabo por los Líderes Emergentes de la Sociedad Interamericana de Cardiología (SIAC), cubriendo diferentes aspectos del impacto sobre el aparato cardiovascular de las ETD: el Proyecto NET-Heart (del inglés, Neglected Tropical Diseases and other Infectious Diseases Affecting the Heart).

Abstract Neglected tropical diseases (NTD) are a group of diseases with high prevalence in tropical and subtropi cal countries. They are associated to poverty and underdevelopment. Due to its high morbimortality, these conditions are considered a health crisis. The impact of these diseases can be worsened by the poor socioeconomic status of the affected countries, most of them under-developed, which affects the health care provided to patients. The morbidity of these diseases is explained by the wide organic impairment that they produce. The cardiovascular system is par ticularly affected, which explains the high morbimortality of NTD. In this article, we review the key issues of a project elaborated by Emerging Leaders of the Interamerican Society of Cardiology (SIAC), about the cardiovascular impact of NTD: the NET-Heart Project (Neglected Tropical Diseases and other Infectious Diseases affecting the Heart).

Early prognostic value of an Algorithm based on spectral Variables of Ventricular fibrillAtion from the EKG of patients with suddEn cardiac death: A multicentre observational study (AWAKE) / Valor pronóstico precoz de un algoritmo basado en variables espectrales de la fibrilación ventricular del ECG de pacientes con muerte súbita cardiaca: estudio observacional multicéntrico (AWAKE)

Abstract Objective: Ventricular fibrillation (VF)-related sudden cardiac death (SCD) is a leading cause of mortality and morbidity. Current biological and imaging parameters show significant limitations on predicting cerebral performance at hospital admission. The AWAKE study (NCT03248557) is a multicentre observational study to validate a model based on spectral ECG analysis to early predict cerebral performance and survival in resuscitated comatose survivors. Methods: Data from VF ECG tracings of patients resuscitated from SCD will be collected using an electronic Case Report Form. Patients can be either comatose (Glasgow Coma Scale GCS --- ≤8) survivors undergoing temperature control after return of spontaneous circulation (RoSC), or those who regain consciousness (GCS = 15) after RoSC; all admitted to Intensive Cardiac Care Units in 4 major university hospitals. VF tracings prior to the first direct current shock will be digitized and analyzed to derive spectral data and feed a predictive model to estimate favorable neurological performance (FNP). The results of the model will be compared to the actual prognosis. Results: The primary clinical outcome is FNP during hospitalization. Patients will be categorized into 4 subsets of neurological prognosis according to the risk score obtained from the predictive model. The secondary clinical outcomes are survival to hospital discharge, and FNP and survival after 6 months of follow-up. The model-derived categorisation will be also compared with clinical variables to assess model sensitivity, specificity, and accuracy. Conclusions: A model based on spectral analysis of VF tracings is a promising tool to obtain early prognostic data after SCD.

Resumen Objetivo: La muerte súbita (MS) por fibrilación ventricular (FV) es una importante causa de morbilidad y mortalidad. Los métodos biológicos y de imagen actuales muestran limitaciones para predecir el pronóstico cerebral al ingreso hospitalario. AWAKE es un estudio observacional, multicéntrico, con el objetivo de validar un modelo basado en el análisis espectral del elec- trocardiograma (ECG), que predice precozmente el pronóstico cerebral y la supervivencia en pacientes resucitados y en estado de coma. Métodos: Se recogerán datos de los ECG con FV de pacientes reanimados de MS. Los pacientes pueden ser tanto supervivientes en estado de coma (Glasgow Coma Scale GCS ≤ 8) sometidos a control de temperatura tras la recuperación de circulación espontánea (RCE), como aquellos que recuperan la consciencia (GCS = 15) tras RCE; todos ellos ingresados en unidades de terapia intensiva cardiológica de 4 hospitales de referencia. Los registros de FV previos al primer choque se digitalizarán y analizarán para obtener datos espectrales que se incluirán en un modelo predictivo que estime el pronóstico neurológico favorable (PNF). El resultado del modelo se comparará con el pronóstico real. Resultados: El objetivo principal es el PNF durante la hospitalización. Los pacientes se categorizarán en 4 subgrupos de pronóstico neurológico según la estimación de riesgo obtenida en el modelo predictivo. Los objetivos secundarios son supervivencia al alta hospitalaria, y PNF y supervivencia a los 6 meses. El resultado de este modelo también se comparará con el pronóstico según variables clínicas. Conclusiones: Un modelo basado en el análisis espectral de registros de FV es una herramienta prometedora para obtener datos pronósticos precoces tras MS por FV.
