In this issue of the Archives, Beatty and colleagues1 demonstrate that the 6-minute walk test (6MWT) provided, at low cost, very useful prognostic information in ambulatory patients with coronary heart disease. In 556 patients with stable coronary heart disease followed up for 8 years, cardiovascular events (eg, heart failure, myocardial infarction, and death) occurred in 218 (39.2%). Patients in the lowest quartile of 6MWT distance (87-419 m) had 4 times the rate of cardiovascular events as those in the highest quartile (544-837 m) (P < .001). Each SD decrease in 6MWT distance (104 m) was associated with a 55% higher rate of cardiovascular events.
