“…Importantly, the distance covered during the 6MWT is a mortality (all‐cause or cardiac) and worsening HF predictor in subjects with HF but not independent from cardiopulmonary exercise test parameters . The fact that 6MWT is not an independent predictor when peak oxygen uptake is included in multivariate analysis is probably due to their significant correlation In fact, in patients with Chagas heart disease, a recent study found significant correlation between the distance covered at 6MWT and the predicted peak oxygen uptake . Therefore, both tests (6MWT and cardiopulmonary exercise test) may give similar prognostic value and therefore reinforces the importance of 6MWT in underprivileged areas where cardiopulmonary exercise test is rarely available.…”

“…Therefore, the correlations of these parameters with 6MWT in ChD point out the important clinical application of this examination in this population. Moreover, others demonstrated the correlation between the distance covered at 6MWT and predicted peak oxygen uptake in ChD. Together with the fact that the 6MWT is simple to perform and easy to interpret, 6MWT becomes a test that can be adopted in endemic areas to evaluate patients with ChD, as also recommended for patients with HF .…”

“…Por su parte el IMC explica en algún porcentaje el VO 2 en tres investigaciones y también en esta investigación (R 2 = 0,034). El sexo es parte del modelo predictivo en nuestro estudio y en el estudio de Costa 5 , pero la investigación de Ingle 11 no lo incluye ya que se realizó sólo con hombres, y la edad aparece en tres ecuaciones de la tabla 5. Las variables que se asocian al VO 2 máx.…”

“…a prueba de caminata de seis minutos (P6CM) no es invasiva, es estandarizada fácil de realizar 1,2 , de esfuerzo submáximo y se mide la distancia recorrida 3,4 . Se ha documentado que la distancia es información limitada de la capacidad funcional siendo necesario un modelo predictivo del VO 2 máx 5 . De hecho la distancia se ha relacionado con la capacidad de consumir oxígeno encontrándose relaciones significativas entre estas variables en personas con patologías, pudiendo ser distinto en personas saludables 6 .…”
