Over the last few years, the use of exercise tests has come to be recognized as a convenient method of evaluating respiratory function, because the reserves of the various systems in the human body should be known in order to provide a more complete portrayal of the functional capacities of the patient. Because walking is one of the main activities of daily living, walk tests have been proposed in order to measure the state or the functional capacity of patients. The six-minute walk test has proven to be reproducible and is well tolerated by patients. It evaluates the distance a person can walk on a flat, rigid surface in six minutes. Its main objective is to determine exercise tolerance and oxygen saturation during submaximal exercise. In this review, we present various clinical areas in which the test can provide useful data.Keywords: Hypertension, pulmonary; Pulmonary circulation; Pulmonary heart disease; Exercise.
ResumoNos últimos anos, o uso de testes de exercício é reconhecido como um método conveniente na avaliação da função respiratória em função da necessidade de se conhecer as reservas dos vários sistemas corporais a fim de que uma ideia mais completa sobre as capacidades funcionais do paciente seja obtida. Visto que o ato de andar é uma das principais atividades da vida diária, os testes de caminhada têm sido propostos para medir o estado ou a capacidade funcional do paciente. O teste de caminhada de seis minutos provou ser reprodutível e é bem tolerado pelos pacientes. Ele avalia a distância que uma pessoa pode percorrer sobre uma superfície plana e rígida em seis minutos e tem como principal objetivo a determinação da tolerância ao exercício e da saturação de oxigênio durante um exercício submáximo. Nesta revisão, apresentamos várias áreas clínicas nas quais o teste pode fornecer informações úteis.
had high regional prevalence of AF in 2011. Geographic variation in high risk areas can help identify important geographically connected prognostic factors, aid in targeted intervention strategies, and generate hypotheses regarding underlying causes of AF in the United States and associated territories.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
