Why the study?
Does the 6-MWT distance and self-perceived symptom severity predict all-cause mortality in older patients with chronic heart failure?
Does the 6-MWT distance and self-perceived symptom severity predict all-cause mortality in older patients with chronic heart failure?
The 6-minute walk test and self-perceived breathlessness at night are independent predictors of mortality in older patients with chronic heart failure, particularly those with more than mild left ventricular systolic dysfunction.
