“…In the present study, the relative change in 6MWT was inversely related to the initial 6MWT, suggesting that patients who walked less distance initially improved more than those who walked a longer distance at CR entry. This finding is also in agreement with Tallaj et al, 7 who reported that cardiac patients with lower functional ability at entry of the CR program improved their walking distance more than patients with an initially higher functional ability.…”

“…7,8,13 The change in MCS scores was no different in patients who attended 25 or more sessions versus those attending 24 or fewer sessions, suggesting that groups benefited similarly in the mental component, regardless of the number of sessions attended. The relative change in SF-36 PCS was associated with the relative change in 6MWT, which may be interpreted to suggest that patients who improved more in the 6MWT had an improved perception of physical function after the CR or vice versa.…”

“…The SF-36 PCS scores also improved to a greater extent in the highest tertile versus the lowest tertile (P ϭ .001), although MCS score changes were not different fit from participating in phase II CR. [7][8][9][10][11]13 Ninety-five percent of study patients improved 6MWT distance an average of 21.6% (range ϭ 1%-115%). Patients improved 6-minute walking distance an average of 73.9 m, equating to a functional improvement in average walking speed of 0.5 mph.…”

“…(7) Various studies have shown that the 6MWT is valid and reproducible in patients with heart failure, providing evidence that it is a reliable means of evaluating functional capacity in such patients. (41)(42)(43)(44)(45)(46)(47)(48)(49)(50) As a predictor of mortality in patients who are candidates for lung transplantation, the 6MWT has shown high sensitivity; a 6MWD of less than 300 m was associated with much earlier mortality among patients on the waiting list for transplantation. (26) Recently, there have been a few studies demonstrating the utility of the 6MWT in the field of solid organ transplantation, and the results have varied across studies.…”

Over the last few years, the use of exercise tests has come to be recognized as a convenient method of evaluating respiratory function, because the reserves of the various systems in the human body should be known in order to provide a more complete portrayal of the functional capacities of the patient. Because walking is one of the main activities of daily living, walk tests have been proposed in order to measure the state or the functional capacity of patients. The six-minute walk test has proven to be reproducible and is well tolerated by patients. It evaluates the distance a person can walk on a flat, rigid surface in six minutes. Its main objective is to determine exercise tolerance and oxygen saturation during submaximal exercise. In this review, we present various clinical areas in which the test can provide useful data.Keywords: Hypertension, pulmonary; Pulmonary circulation; Pulmonary heart disease; Exercise. ResumoNos últimos anos, o uso de testes de exercício é reconhecido como um método conveniente na avaliação da função respiratória em função da necessidade de se conhecer as reservas dos vários sistemas corporais a fim de que uma ideia mais completa sobre as capacidades funcionais do paciente seja obtida. Visto que o ato de andar é uma das principais atividades da vida diária, os testes de caminhada têm sido propostos para medir o estado ou a capacidade funcional do paciente. O teste de caminhada de seis minutos provou ser reprodutível e é bem tolerado pelos pacientes. Ele avalia a distância que uma pessoa pode percorrer sobre uma superfície plana e rígida em seis minutos e tem como principal objetivo a determinação da tolerância ao exercício e da saturação de oxigênio durante um exercício submáximo. Nesta revisão, apresentamos várias áreas clínicas nas quais o teste pode fornecer informações úteis.

“…For a patient with advanced HF and/or someone severely deconditioned, a 6MWT may constitute the equivalent to a maximal symptom-limited exercise test. [45][46][47][48][49] However, to a middle-aged man with stable CHD, it may comprise only a modest effort. In summary, the 6MWT is convenient, but does not assess maximal CRF or detect ischemia, arrhythmias, or other pathological responses to exercise elicited by maximal tests.…”

Symptom-limited (maximal) exercise testing before cardiac rehabilitation (CR) was once an unambiguous standard of care. In particular, it served as an important screen for residual ischemia and instability before initiating a progressive exercise training regimen. However, improved revascularization and therapy for coronary heart disease has led many clinicians to downplay this application of exercise testing, especially because such testing is also a potential encumbrance to CR enrollment (delaying ease and efficiency of enrollment after procedures and hospitalizations) and patient burden (eg, added costs, logistic hassle, and anxiety). Nonetheless, exercise testing has enduring value for CR, especially because it reveals dynamic physiological responses as well as ischemia, arrhythmias, and symptoms pertinent to exercise prescription and training and to overall stability and prognosis. Moreover, as indications for CR have expanded, the value of exercise testing and functional assessment is more relevant than ever in the growing population of eligible patients, including those with heart failure, valvular heart disease, and posttransplantation, especially as current patients also tend to be more clinically complex, with advanced ages, multimorbidity, frailty, and obesity. This review focuses on the appropriate use of exercise testing in the CR setting. Graded exercise tests, cardiopulmonary exercise tests, submaximal walking tests, and other functional assessments (strength, frailty) for CR are discussed.
