Efeito de 16 semanas de treinamento físico, sem controle alimentar, sobre o perfil lipídico e pressão arterial

Este estudo investiga a importância do exercício físico na prevenção de Doenças Crônicas Não Transmissíveis. Seu objetivo é verificar o efeito de 16 semanas de exercícios físicos no perfil lipídico e pressão arterial. O grupo de estudo foi composto por 12 voluntários, com faixa etária de 40 a 60 anos, com média de colesterol total e LDL insignificantemente acima dos valores limítrofe e pré-hipertensos. Os indivíduos foram submetidos á avaliação médica; análise laboratorial; teste físico e 16 semanas de treinamento físico com frequência de três vezes por semana. Todos os procedimentos foram repedidos ao final. Houve redução significativa do Índice de Massa Corporal, Colesterol LDL, Pressão Arterial Diastólica e aumento da glicemia e do desempenho físico. Não se modificaram o Colesterol Total, Colesterol HDL e Triglicerídeos. O programa de exercícios, mesmo sem o controle de dieta, foi suficiente para provocar as alterações descritas do perfil lipídico, comprovando sua importância na prevenção de doenças cardíacas.Departamento de Educación Físic

Comparison of two technics of extracorporeal circulation (Conventional and Mini ECC), in the trans and post-operative periods of cardiac surgery

Abstract Objective: This study aimed to compare the effects of two different perfusion techniques: conventional cardiopulmonary bypass and miniature cardiopulmonary bypass in patients undergoing cardiac surgery at the University Hospital of Santa Maria - RS. Methods: We perform a retrospective, cross-sectional study, based on data collected from the patients operated between 2010 and 2013. We analyzed the records of 242 patients divided into two groups: Group I: 149 patients undergoing cardiopulmonary bypass and Group II - 93 patients undergoing the miniature cardiopulmonary bypass. Results: The clinical profile of patients in the preoperative period was similar in the cardiopulmonary bypass and miniature cardiopulmonary bypass groups without significant differences, except in age, which was greater in the miniature cardiopulmonary bypass group. The perioperative data were significant of blood collected for autotransfusion, which were higher in the group with miniature cardiopulmonary bypass than the cardiopulmonary bypass and in transfusion of packed red blood cells, which was higher in cardiopulmonary bypass than in miniature cardiopulmonary bypass. In the immediate, first and second postoperative period the values of hematocrit and hemoglobin were higher and significant in miniature cardiopulmonary bypass than in the cardiopulmonary bypass, although the bleeding in the first and second postoperative days was higher and significant in miniature cardiopulmonary bypass than in the cardiopulmonary bypass. Conclusion: The present results suggest that the miniature cardiopulmonary bypass was beneficial in reducing the red blood cell transfusion during surgery and showed slight but significant increase in hematocrit and hemoglobin in the postoperative period
