ABSTRACT
Background:
The evaluation of the functional capacity of patients with chronic heart failure (HF) by means of the distance covered in the six-minute walk test (6MWT) has assumed great importance, since the 6MWD is a predictor of mortality and hospitalization in this population, however the determinants of better distance traveled in patients with HF are little explored, especially in the Brazilian population.Objective:
To evaluate the determinants of 6MWD in patients with chronic HF.Methods:
A cross-sectional study was performed with 81 HF patients in outpatient treatment. 6MWD was used as the outcome variable and sociodemographic, clinical, physical-functional and emotional data were submitted to multiple regression analysis using the stepwise method with a significance level of 5%.Results:
Mean age of participants was 56.71 years; the 6MWD showed a bivariate correlation with age (r = -0.27, p = 0.01), maximal inspiratory pressure (r = 0.42, p < 0.01), maximal expiratory pressure (r = 0.36, p < 0.01), handgrip strength (r = 0.38, p < 0.01), Borg scale (-0.22, p = 0.04), Charlson index (r = -0.25, p = 0.02) and modified Medical Research Council (mMRC) dyspnea scale (r = -0.42, p < 0.01). In the multivariate analysis, the variables gender (p = 0.001), age (0.004), forced vital capacity (FVC) (p = 0.016) and mMRC (p = 0.001) simultaneously explained 37% of variance in the 6MWD.Conclusion:
Higher levels of dyspnea on daily life activities, female sex, older age and lower forced vital capacity are determinants of a shorter 6MWD in patients with chronic HF
