PG - 177-87 LID - S1836-9553(13)70182-6 [pii] LID - 10.1016/S1836-9553(13)70182-6 [doi] AB - QUESTION: Does the distance covered during a 6-minute walk test predict risk of death or hospitalisation for cardiovascular reasons in men with stable heart failure over three years of follow-up? DESIGN: Prospective observational study. PARTICIPANTS: 243 men with stable systolic heart failure, with a mean age of 60 yr (SD 11) and left ventricular ejection fraction of 29% (SD 8). According to the New York Heart Association (NYHA) classification, 15% of the participants were in Class I, 44% in Class II, 37% in Class III, and 4% in class IV. OUTCOME MEASURES: The exercise capacity of participants was measured using the 6-minute walk test. The participants were followed up for at least three years in the case of survivors. The primary end-points of the survival analyses included cardiovascular death or urgent cardiovascular hospitalisation. RESULTS: During the 3-year follow-up, 44% of the participants died, and 69% died or required hospitalisation for cardiovascular reasons. A multivariate analysis showed that the shorter the distance covered in the 6-minute walk test, the greater the 1-year and 3-year mortality risk. Participants with a 6-minute walk test
