Resumo

Introdução: Os doentes internados com insuficiência cardíaca apresentam uma dependência funcional significativa, comprometimento do desempenho nas atividades de vida diária e baixa tolerância ao exercício. A quantidade de Exercício está diretamente relacionada com os seus benefícios e o volume de exercício realizado deve ser ajustado aos parâmetros de segurança. O objetivo deste estudo é avaliar o volume de exercício realizado por doentes internados com insuficiência cardíaca e sua relação com a capacidade funcional, procurando encontrar um nível basal de volume de exercício seguro e eficaz.

Metodologia: Estudo quase-experimental envolvendo 50 doentes internados que realizaram um programa de exercício físico aeróbio. O volume de exercício foi registado em termos de número de voltas no cicloergómetro, metros caminhados, degraus subidos e tempo total de exercício. A perceção subjetiva de esforço foi avaliada em todas as sessões de treino no início e no final. Os doentes realizaram dois testes de 6 minutos de marcha (T6MM).

Resultados: Foram realizadas 987 sessões de treino. A maioria dos doentes apresentava uma capacidade funcional significativamente comprometida: 81,9% são NYHA III e 73,6% apresentam Insuficiência Cardíaca com fração de ejeção reduzida. A perceção subjetiva de esforço durante o internamento reduziu significativamente: 6 (±3) (admissão) e 2(±2) (alta). Os doentes que realizaram maior volume de exercício caminharam uma maior distância no T6MM à data da alta.

Conclusão: Um maior volume de exercício aeróbio está relacionado com melhores resultados em termos de funcionalidade. Uma média de mais de 10 minutos por sessão parece ser mais eficaz em termos de melhoria da capacidade funcional.
