Diagnostic characteristics and prognoses of primary-care patients referred for clinical exercise testing: a prospective observational study.

ABSTRACT:

Evaluation of angina symptoms in primary care often includes clinical exercise testing. We sought to identify clinical characteristics that predicted the outcome of exercise testing and to describe the occurrence of cardiovascular events during follow-up.
