The 6-minute walk test may improve cardiovascular risk prediction in patients with stable coronary heart disease, researchers found.
Even after adjustment for traditional cardiovascular risk factors and measures of cardiac disease severity, each standard deviation decrease in walk distance was associated with a 30% greater risk of MI, heart failure, or death (HR 1.30, 95% CI 1.10 to 1.53), according to Alexis Beatty, MD, of the University of California San Francisco, and colleagues.
