Resistance and Balance Training Improves Functional Capacity in Very Old Participants Attending Cardiac Rehabilitation After Coronary Bypass Surgery

Abstract

There were significant improvements in all measured variables in very old adults participating in CR soon after CABG. With additional functional exercise training, participants randomized to IG improved significantly more than those randomized to CG on 6-MWD, TUG time, and relative workload.

Cardiac Rehabilitation in Very Old Adults: Effect of Baseline Functional Capacity on Treatment Effectiveness

“…This result is particularly relevant in view of the fact that a 17% increase in peak aerobic capacity after 3 months of exercise training was reported in a group of individuals after an acute coronary event or cardiac surgical intervention much younger (61 ± 11) than the current study cohort . The current findings are consistent with those reported in a previous study that obtained a 13.5% increase in 6MWT distance and a 16.2% increase in VO 2 peak in older adults with a 3‐week CR program after cardiac surgery.…”

“…The improvements in exercise tolerance, endurance, and muscle strength obtained in a population with a mean age of 80 are consistent with those of a recent study demonstrating improved functional capacity after cardiac surgery in participants aged 80 and older in whom routine CR was integrated with resistance and balance training.…”

“…For the purposes of this analysis, in accordance with results of previous studies in similar populations, a 15% increase in physical performance indexes from baseline screening to the end of CR was chosen to represent a clinically meaningful improvement in very old adults.…”

“…Third, availability of only two measurements (at baseline and 4 weeks later) cannot exclude the influence of a regression to the mean effect, but the average improvement observed in VO 2 peak is close to that obtained in similarly old individuals attending a 3-week CR program after cardiac surgery. 20 Finally, a selection bias represented by the exclusion of individuals with cognitive decline or disability and of those with moderate to severe left ventricular systolic dysfunction might limit generalizability of the findings to older adults routinely hospitalized for cardiac disease.…”

Reabilitacao cardiaca em pacientes submetidos a cirurgia de revascularizacao do miocardio

“…Quanto ao TC6, alguns pesquisadores observaram uma melhora na distância percorrida no TC6 em pacientes com idade acima de 75 anos quando comparado com pacientes com idade inferior a 65 anos, mostrando que pacientes mais idosos se beneficiaram mais do que pacientes menos idosos, melhorando sua capacidade funcional 16,17 Após o treinamento dos pacientes no PRC durante 3 meses, não observamos na avaliação do questionário de qualidade de vida SF-36 melhora nos oito componentes avaliados, diferentemente de um outro estudo sobre os benefícios do PRC para pacientes submetidos à CRM, no qual os pacientes realizaram um acompanhamento no programa em tempo médio de 11 semanas, obtendo melhora em três componentes do questionário: capacidade funcional, percepção do estado geral de saúde e saúde mental 21 . Barnason et al 22 avaliaram pacientes após a CRM no tempo basal (imediatamente após a cirurgia), 3, 6 e 12 meses, constatando através do teste SF-36 que no tempo basal os escores de sete dos oito componentes do SF-36 eram significativamente menor do que após 3, 6 e 12 meses de cirurgia.…”
