The Veterans Exercise Testing Study (VETS)

Begun in 1987, the VETS is an ongoing, prospective evaluation of veteran subjects referred for exercise testing for clinical reasons, designed to address exercise test, clinical, and lifestyle factors and their association with health outcomes. The data base has been useful in answering many epidemiological questions related to the diagnostic and prognostic utility of the exercise test, evaluating the influence of various risk factors on outcomes, and in assessing cost implications of lifestyle factors such as fitness and physical activity patterns. Furthermore, it has been used to document and possibly explain the obesity paradox. It contains demographic, clinical and extensive exercise test results on over 10,000 patients followed for vital status for a median of 14 years.
