RESUMEN
BACKGROUND: Neuromuscular electrostimulation has become a promising issue in cardiovascular rehabilitation. However there are few articles published in the literature regarding neuromuscular electrostimulation in patients with heart failure during hospital stay. METHODS: This is a randomized controlled pilot trial that aimed to investigate the effect of neuromuscular electrostimulation in the walked distance by the six-minute walking test in 30 patients admitted to ward for heart failure treatment in a tertiary cardiology hospital. Patients in the intervention group performed a conventional rehabilitation and neuromuscular electrostimulation. Patients underwent 60 minutes of electrostimulation (wave frequency was 20 Hz, pulse duration of 20 us) two times a day for consecutive days until hospital discharge. RESULTS: The walked distance in the six-minute walking test improved 75% in the electrostimulation group (from 379.7 ± 43.5 to 372.9 ± 46.9 meters to controls and from 372.9 ± 62.4 to 500 ± 68 meters to electrostimulation, p<0.001). On the other hand, the walked distance in the control group did not change. CONCLUSION: The neuromuscular electrostimulation group showed greater improvement in the walked distance in the six-minute walking test in patients admitted to ward for compensation of heart failure.

BACKGROUND: Heart failure (HF) is an important public health problem, of which main clinical symptoms are dyspnea and fatigue. Noninvasive ventilatory support has been used as adjuvant therapy in cardiac rehabilitation in order to improve the functional capacity of patients. OBJECTIVE: To evaluate the functional capacity of patients with HF submitted to ventilatory support. METHODS: We evaluated the sociodemographic information, as well as data on quality of life, blood pressure (BP), peripheral oxygen saturation (SpO2), dyspnea, lactate concentration before and after the 6-minute walk test (6MWT) and the distance walked by patients of both sexes with chronic heart failure (CHF), with left ventricular ejection fraction (LVEF) < 45.0% , randomized in two groups: control and CPAP (the group used CPAP - 10 cmH2O for 30 minutes). RESULTS: A total of 12 patients, of which 8 were males, with CHF functional class II and III (NYHA) participated in the study. The patients had mean LVEF of 35.3 ± 8.7 and mean age was 46.3 ± 10.3 years. When comparing the control group with the CPAP group at the end of the 6th minute, there was a significant difference between the groups regarding SpO2 values ( CONTROL: 93.6 ± 1.5 % vs CPAP: 96.1±1.8%; p = 0.027), index of dyspnea ( CONTROL: 13.1 ± 1.16 vs CPAP: 11 ± 0.8; p = 0.009), lactate concentration ( CONTROL: 3.3 ± 0.7 mmol/l vs CPAP: 2.3 ± 0.5 mmol/l; p = 0.025) and distance walked at the 6MWT (CONTROL: 420.6 ± 73.8 m vs CPAP: 534 ± 89.91 m; p = 0.038). CONCLUSION: The previous use of the CPAP had beneficial effects on SpO2, index of dyspnea, lactate concentration, double product and the distance walked at the 6MWT in patients with CHF when performing the 6MWT.

FUNDAMENTO: A insuficiência cardíaca é um importante problema de saúde pública, apresentando a dispneia e a fadiga como principais sintomas clínicos. A utilização do suporte ventilatório não invasivo vem atuando como coadjuvante da reabilitação cardíaca na tentativa de melhorar a capacidade funcional dos pacientes. OBJETIVO: Avaliar a capacidade funcional de pacientes com insuficiência cardíaca submetidos ao suporte ventilatório. MÉTODOS: Foram avaliados dados sociodemográficos, qualidade de vida, FC, pressão arterial (PA), saturação periférica de oxigênio (SpO2), dispneia, concentração de lactato, antes e depois do teste de caminhada de 6 minutos, e a distância percorrida de pacientes com insuficiência cardíaca crônica (ICC), de ambos os sexos, com fração FEVE < 45,0 por cento, randomizados em dois grupos: controle e CPAP (utilizou CPAP 10 cmH2O por 30 minutos). RESULTADOS: Participaram 12 pacientes com ICC classe funcional II e III (NYHA), com média de fração de ejeção do ventrículo esquerdo (FEVE, por cento) de 35,3 ± 8,7, sendo que 8 eram do sexo masculino. A média de idade foi de 46,3 ± 10,3 anos. Na comparação entre os grupos Controle e CPAP, no final do 6º min, foi encontrada diferença significativa nos valores de SpO2 por cento entre os grupos (Controle: 93,6 ± 1,5 por cento vs CPAP: 96,1 ± 1,8 por cento; p = 0,027), dispneia (Controle: 13,1 ± 1,16 vs CPAP: 11 ± 0,8; p = 0,009), concentração de lactato (Controle: 3,3 ± 0,7 mmol/l vs CPAP: 2,3 ± 0,5 mmol/l; p = 0,025), e distância percorrida no TC6 (Controle: 420,6 ± 73,8 m vs CPAP: 534 ± 89,91 m; p = 0,038). CONCLUSÃO: A realização prévia do CPAP apresentou efeitos benéficos na SpO2, na dispneia, na concentração de lactato, no duplo produto e na distância percorrida no TC6 de pacientes com ICC na realização do TC6.
