To describe the clinical and sociodemographic characteristics of participants as well as discontinuation and mortality rates in a cardiac rehabilitation programme (CRP) tailored to Chagas disease (CD).Participants underwent functional capacity, anthropometry and cardiac function evaluations before beginning a CRP. Univariate and multivariate Cox proportional hazards models were performed to investigate the associations between clinical and sociodemographic characteristics at baseline with discontinuation rates and deaths.Forty-two patients were enrolled in the CRP (61.9% men, mean age of 58.1 ± 11.8 years). During a median follow-up period of 10.8 months, 74% discontinued and 14% died while enrolled in CRP. 34% of the patients who discontinued CRP died during follow-up. White race (HR = 0.09; 95% CI 0.01-1.00), right ventricular systolic dysfunction (HR = 10.54; 95% CI 1.24-89.50) and oxygen pulse (HR = 0.69; 95% CI 0.48-0.99) were independently associated with death while enrolled in CRP. Married status (HR = 0.44; 95% CI 0.21-0.95) was independently associated with discontinuation rates from CRP. VOIn this population, sociodemographic aspects and severity of CD were important determinants of CRP discontinuation and mortality.Décrire les caractéristiques cliniques et sociodémographiques des participants ainsi que les taux d'abandon et de décès dans un programme de réadaptation cardiaque (PRC) adapté à la maladie de Chagas (MC). MÉTHODES: Les participants ont subi des évaluations de la capacité fonctionnelle, de l'anthropométrie et de la fonction cardiaque avant de commencer un PRC. Des modèles de risques proportionnels de Cox univariés et multivariés ont été appliqués pour étudier les associations entre les caractéristiques cliniques et sociodémographiques au départ avec les taux d'abandon et les décès. RÉSULTATS: 42 patients ont été enrôlés dans le PRC (61,9% d'hommes, âge moyen de 58,1 ± 11,8 ans). Au cours d'une période médiane de suivi de 10,8 mois, 74% ont abandonné et 14% sont décédés durant leur enrôlement au PRC. 34% des patients qui ont arrêté le PRC sont décédés au cours du suivi. La race blanche (HR = 0,09; IC95%: 0,01-1,00), le dysfonctionnement systolique ventriculaire droite (HR = 10,54; IC95%: 1,24-89,50) et le pouls d'oxygène (HR = 0,69; IC95%: 0,48-0,99) étaient indépendamment associés avec le décès lors de l’enrôlement au PRC. Le statut marié (HR = 0,44; IC95%: 0,21-0,95) était indépendamment associé aux taux d'abandon de la CRP. Le pic de VO2 (HR = 0,85; IC95%: 0,74-0,98) et l'arrêt du PRC pour des raisons liées à la MC (HR = 8,33; IC95%: 1,91 à 36,27) étaient les variables indépendamment associées au décès après l'arrêt du PRC.Dans cette population, les aspects sociodémographiques et la sévérité de la MC étaient des déterminants importants de l'arrêt du PRC et du décès.

O objetivo do presente estudo foi verificar o efeito agudo do alongamento estático e da automassagem com foam rolling nos membros inferiores sobre o desempenho de salto vertical. Fizeram parte do presente estudo 10 participantes do sexo feminino fisicamente ativas e aparentemente saudáveis. As participantes realizaram dois protocolos com entrada aleatória, conduzidos pela técnica do quadrado latino, sendo eles: 1) condição controle (CC); 2) automassagem com foam rolling (FR) e 3) alongamento estático (AE). O Sargent Jump Test foi utilizado para testar a potência de membros inferiores, sendo realizado após as condições FR e AE. Ambas as condições FR e AE foram realizadas paras as regiões anterior e posterior da coxa e posterior da perna em 4 séries com 30 segundos de duração para cada posição, respeitando um intervalo passivo de 30 segundos entre cada série. No que diz respeito às condições experimentais, tanto a condição AE (p = 0,010) quanto a condição FR (p = 0,042) aumentaram significativamente a distância alcançada nos saltos em relação a condição CC. Não foram observadas diferenças significativas entre as condições experimentais (AE vs FR) testadas (p =1,000). De acordo com os resultados do presente estudo, estratégias pré exercício como FR e AE parecem melhorar a potência de membros inferiores no Sargent Jump Test.

Chagas disease is an important infection in Latin America but it is also reported in non-endemic countries all over the world. Around 30% of infected patients develop chronic Chagas cardiopathy, which is responsible for most poor outcomes, mainly heart failure, arrhythmias and thromboembolic events. Of all thromboembolic events, stroke is the most feared, due to the high probability of evolution to death or disability. Despite its importance, the actual incidence of cardioembolic ischemic stroke in Chagas disease is not completely known. The Instituto de Pesquisa Evandro Chagas/Fundação Oswaldo Cruz (IPEC-FIOCRUZ) score aims to propose prophylaxis strategies against cardioembolic ischemic stroke in Chagas disease based on clinical risk–benefit. To date, the IPEC-FIOCRUZ score is considered the best tool to identify patients for stroke prophylaxis in Chagas disease according the Latin American guideline and Brazilian consensus. It can prevent many cardioembolic strokes that would not be predicted, by applying the current recommendations to other cardiopathies. However, the IPEC-FIOCRUZ score still requires external validation to be used in different Chagas disease populations with an appropriate study design.
