Validation of exercise-enhanced risk assessment of coronary heart disease events: longitudinal changes in incidence in Seattle community practice.

Noninvasive criteria developed in a learning series for exercise-enhanced risk assessment for events due to coronary heart disease have been applied to a test series in a later population sample. Men in the same age and risk groups for each pretest clinical classification show similar gradients of risk. Thus, exercise-enhanced criteria for risk assessment are validated. Age-standardized event rates show a reduction longitudinally in healthy men and patients who have had coronary bypass surgery.
