Inspirational Muscle Training with Linear Device in Post-Operative Myocardial Revascularization: Systematic Review

Cardiovascular diseases are considered one of the main causes of death in the world and one of the forms of treatment is cardiac surgery, including myocardial revascularization. After the good results, the surgery is related to pulmonary complications, causing respiratory muscle dysfunction, loss of muscle strength and decreased lung capacities and volumes. Physiotherapy uses several techniques and inspiratory muscle training emerges as a technique that aims to improve respiratory muscle strength and endurance. The aim of this study was to describe the effects and importance of inspiratory muscle training in the treatment of pulmonary dysfunction in the postoperative period of coronary artery bypass graft surgery. This is a systematic literature review, carried out with controlled and randomized clinical trials, indexed in the Cochrane Library, Lilacs, PEDro, Pubmed and SciELO databases, published between 2009 and July 2021 in Portuguese, English and Spanish. 08 articles make up this review. It was concluded that inspiratory muscle training, although there is no specific protocol on how to perform it, proved to be a safe, easy to apply and effective technique in the treatment of pulmonary dysfunctions and of paramount importance for rehabilitation in the postoperative period of revascularization of the myocardium.
