Benefits of exercise training and the correlation between aerobic capacity and functional outcomes and quality of life in elderly patients with coronary artery disease

Abstract

Cardiopulmonary exercise training is beneficial to people with coronary artery disease (CAD). Nevertheless, the correlation between aerobic capacity, and functional mobility and quality of life in elderly CAD patients is less addressed. The purpose of the current study is to investigate the beneficial effects of exercise training in elderly people with CAD, integrating exercise stress testing, functional mobility, handgrip strength, and health-related quality of life. Elderly people with CAD were enrolled from the outpatient clinic of a cardiac rehabilitation unit in a medical center. Participants were assigned to the exercise training group (N = 21) or the usual care group (N = 15). A total of 36 sessions of exercise training, completed in 12 weeks, was prescribed. Echocardiography, exercise stress testing, the 6-minute walking test, Timed Up and Go test, and handgrip strength testing were performed, and the Short-Form 36 questionnaire (SF-36) was administered at baseline and at 12-week follow-up. Peak oxygen consumption improved significantly after training. The heart rate recovery improved from 13.90/minute to 16.62/minute after exercise training. Functional mobility and handgrip strength also improved after training. Significant improvements were found in SF-36 physical function, social function, role limitation due to emotional problems, and mental health domains. A significant correlation between dynamic cardiopulmonary exercise testing parameters, the 6-minute walking test, Timed Up and Go test, handgrip strength, and SF-36 physical function and general health domains was also detected. Twelve-week, 36-session exercise training, including moderate-intensity cardiopulmonary exercise training, strengthening exercise, and balance training, is beneficial to elderly patients with CAD, and cardiopulmonary exercise testing parameters correlate well with balance and quality of life.

“…Efectos del entrenamiento aeróbico y de fuerza combinados vs entrenamiento aeróbico sobre capacidad aeróbica y fuerza muscular en pacientes con enfermedad de las arterias coronarias. (Piché et al, 2019), movilidad funcional (Chen et al, 2014) y rendimiento cardíaco (Piché et al, 2019) en pacientes con esta patología. Además, se encontraron mejoras significativas (Xanthos et al, 2017) y no significativas (Hollings et al, 2017, Marzolini et al, 2012 obtienen beneficios funcionales y de pronóstico en esta enfermedad (Kavanagh et al, 2002).…”

The aerobic capacity in patients with antisynthetase syndrome and dermatomyositis

“…Several researchers have shown the association between decreased aerobic capacity and increased risk of morbidity and mortality associated with CVDs [11][12][13]. Thus, increased aerobic capacity represents a significant improvement in functional capacity and quality of life, increased perception of self-reported physical health and a reduction in CVDs and their risk factors [14].…”

Comparison of Functional Capability, Flexibility, Strength and Quality of Life in Aged Women Engaged in Resistance Exercise, Weight-Bearing Training or Hydro-Gymnastics

“…Weight bearing exercises have been gaining practitioners and credibility. This kind of exercise tries to reach the improvement of physical capabilities most requested to perform the daily tasks, like proprioception, balance, agility, motor coordination, flexibility, force and muscular endurance [32,33].…”

“…Some researchers have been observing that in general the physical exercise, even when performed in a moderate intensity, is able to significantly promote the increase in strength [34], cardiorespiratory endurance [33], flexibility [35], and functional capability [32] in elderly people. Unfortunately little is known about which exercise modality brings additional benefits to this population [36].…”
