Improved percent-predicted peak VO2 is associated with lower risk of hospitalization in patients with coronary heart disease. Analysis from the FRIEND registry

Background Normal standards for peak oxygen consumption (VO2peak) are controversial because they tend to be population and protocol specific. This study was undertaken to examine the association between percentage of age-predicted VO2peak and all-cause hospital readmission in cardiac outpatients who were referred to an exercise-based secondary prevention program. Methods Hospital readmission was assessed in 1283 male patients with coronary heart...
