“…The type of exertion put forth during T6´ in HF has been considered similar to that of daily activities 12,13 , i.e., the six-minute walk is a submaximal 14 exercise test. Carreira et al 15 concluded that T6´ identifi es signifi cant hemodynamic stress and a large number of severe arrhythmias, in spite of being a better refl ection of daily activities than a maximal oxygen uptake test.…”

OBJECTIVEThis study aimed to assess the true usefulness of the SixMinute Walk Test as a prognostic indicator and its contribution to clinical practice with heart failure patients. METHODSIn order to investigate the actual value of the SixMinute Walk Test as an objective measure of mortality probability in patients with heart failure, the test was applied to 179 stable patients (120 men and 59 women, mean age 58.32 ± 12.7 years, with NYHA class II and III heart failure and an ejection fraction (LVEF) of 34.91 ± 12.4%). Patients were instructed to walk for 6 minutes and then, four hours later, underwent a conventional exercise stress test (as per Naughton Protocol). Patients were followed for an average of eighteen months. RESULTSThe average distance walked was 521.11 ± 76.1 meters. During the follow-up period, 66 patients (36.9%) died. There was a signifi cant correlation between the distance walked during the test and mortality (p < 0.0001). The logistic regression model identifi ed the distance walked during the test as the most important independent predictor of mortality (p = 0.0001). A distance shorter than 520 meters identifi ed the patients with an increased probability of death. There was a signifi cant correlation between the number of metabolic equivalents (METs) measured during the conventional exercise stress testing and mortality rate (p = 0.0001). CONCLUSIONThe Six-Minute Walk test is a simple, safe and powerful method to assess the prognosis of patients with NYHA class II and III heart failure. It is an objective examination that may replace the conventional ergometric test for the prognostic evaluation of these patients.

“…The six-minute walk test (6MW), due to its wide availability, security and ease of implementation, is being used increasingly as an alternative to CPET to evaluate the functional capacity of patients with HF [5][6][7][8] . It is considered a submaximal exercise that mimics everyday activities and is generally well tolerated by patients.…”

“…Comorbidity with the pulmonary vascular axis which is particularly relevant in associated forms of PAH, such as scleroderma, compromise the reliability of the results [131,132]. The test has a ceiling effect as the linear relationship between peak VO 2 and 6MWD is lost in less impaired subjects [71,[133][134][135][136]. This makes it more responsive to change in more severely affected individuals and vice versa in fitter individuals.…”

A culture of exercise testing is firmly embedded in the management of pulmonary arterial hypertension (PAH) but its clinical relevance and utility have recently been under some debate. The six minute walk test (6MWT) has been used as a primary outcome measure to enable the licensing of many of the medications used for this condition. Recent reviews have questioned the validity of this test as a surrogate of clinical outcomes. At the same time, other questions are emerging where exercise testing may be the solution. With the rise in understanding of genetic markers of idiopathic PAH (IPAH), the screening of an otherwise healthy population for incipient pulmonary hypertension (PH) will be required. The proliferation in treatment choices and identification of populations with PH where PAH treatment is not indicated, such as left heart and lung disease, requires more definitive differentiation from patients with PAH. There is a continuing question about the existence and clinical relevance of exercise induced PAH as a cause of unexplained dyspnoea and fatigue and as a latent phase of resting PH. This review presents a summary and critical analysis of the current role of exercise testing in PAH and speculates on future trends.
