Abstract

INTRODUCTION: Heart failure (HF) is a complex syndrome in which effort limitation is associated with deterioration of peripheral musculature. Improving survival rates among these patients have led to the appearance of cases in which other pathologies are associated with HF, such as peripheral vascular insufficiency (PVI). The combination of these two pathologies is common, with significant repercussions for affected patients.OBJECTIVE: To compare functional limitations and quality of life between patients with HF in isolation or HF + PVI.METHOD: Twelve patients with HF+PVI were paired to 12 patients with HF in isolation. All had ejection fraction <40%. The following were conducted: 6 minute walk test (6MWT), chair test (CT), step test (ST), one repetition maximum test (1RM) and quality of life questionnaire.RESULTS: The results for the 6MWT (311±27 vs. 447±29), ST (49±3 vs. 81±10) and CT (17±1 vs. 21±1) were lower in the HF+PVI group than in the HF group (p<0.05). The HF+PVI group exhibited a reduction in the number of steps taken from the first to the second minute of the ST, in relation to the HF group. The HF group exhibited better HR recovery than the HF+PVI group (50±4 vs. 26±3; p<0.05). No differences were found in results for the Borg scale, the peripheral muscle strength test (1RM) or the questionnaires (p>0.05).CONCLUSIONS: The study participants who had mixed disease exhibited a greater degree of functional impairment than the group with HF, without reporting worsened quality of life.

Resumo

INTRODUÇÃO: A insuficiência Cardíaca (IC) é uma síndrome complexa e a limitação ao esforço está associada à piora da musculatura periférica. Devido à melhora na sobrevida destes pacientes, observa-se o surgimento de patologias associadas à IC, como a insuficiência vascular periférica (IVP). A associação das duas patologias é comum e com grandes prejuízos aos pacientes acometidos.OBJETIVO: Comparar as limitações funcionais e a qualidade de vida em IC isolada e IC + IVP.MÉTODO: Doze pacientes com IC+IVP foram pareados a 12 pacientes com IC isolada. Todos possuíam fração de ejeção <40%. Foram realizados: teste da caminhada de seis minutos (TC6M), teste da cadeira (TCAD), teste do degrau (TD), teste de uma repetição máxima (1RM) e questionário de qualidade de vida.RESULTADOS: Os valores obtidos nos testes TC6M (311±27 vs. 447±29), TD (49±3 vs. 81±10) e TCAD (17±1 vs. 21±1) no grupo IC+IVP foram menores do que no grupo IC (p<0,05), respectivamente. O grupo IC+IVP obteve redução do número de degraus alcançados entre o primeiro e o segundo minuto do TD em relação ao grupo IC. O grupo IC apresentou melhor recuperação da FC em relação ao grupo IC+IVP (50±4 vs. 26±3; p<0,05). Não foi encontrada diferença na escala de Borg, na força muscular periférica (1RM) e nos questionários aplicados (p>0,05).CONCLUSÃO: No presente estudo, os participantes com doença mista apresentaram maior comprometimento funcional em relação ao grupo com IC, sem demonstrar piora na qualidade de vida.
