The Importance of the Double Product in the Six-Minute Walk Test to Predict Myocardial Function

Figure 1

(a) Walking distance obtained in 6MWT in the group of patients with heart failure (HF) and in the control group (without HF). Data presented as mean ± SEM. means p <0.05

(b) An increase in the double product corresponding to a 1-meter walk in patients during 6MWT. HF: group with heart failure; without HF: the control group. Data are presented as mean ± SEM. means p <0.05

(c) An increase in the double product in patients during 6MWT. HF: group with heart failure; without HF: the control group. Data are presented as mean ± SEM
