Predictors of Functional Capacity in Chronic Heart Failure: Echocardiography Versus Six-Minute Walk Test

Assessment of exercise capacity in African patients with chronic heart failure using six minutes walk test

BACKGROUND The purpose of this study was to assess the functional capacity during a 6-minute corridor walk and a 6-minute bicycle ergometry exercise in patients with chronic heart failure (CHF). METHOD Thirty five patients with stable CHF were recruited for the study. Each subject performed six minutes corridor walk and 6-minute bicycle ergometry testing. The 6-minute walk required the subjec...

The six-minute walk test.

The American Thoracic Society has issued guidelines for the 6-minute walk test (6MWT). The 6MWT is safer, easier to administer, better tolerated, and better reflects activities of daily living than other walk tests (such as the shuttle walk test). The primary measurement is 6-min walk distance (6MWD), but during the 6MWT data can also be collected about the patient's blood oxygen saturation and...

Heart failure: comparison between six-minute walk test and cardiopulmonary test.

BACKGROUND Chronic heart failure (HF) is a syndrome characterized by reduced cardiac output in relation to the metabolic needs of the organism, as well as metabolic and neurohormonal axis abnormalities. Symptoms such as fatigue and dyspnoea are notorious and stress tests are widely used to assess functional capacity, prognosis and effectiveness of therapeutic interventions in this syndrome. O...

Heart Rate Recovery in the First Minute at the Six-Minute Walk Test in Patients with Heart Failure

BACKGROUND Heart rate recovery at one minute of rest (HRR1) is a predictor of mortality in heart failure (HF), but its prognosis has not been assessed at six-minute walk test (6MWT) in these patients. OBJECTIVE This study aimed to determine the HRR1 at 6MWT in patients with HF and its correlation with six-minute walk distance (6MWD). METHODS Cross-sectional, controlled protocol with 161 ind...
