We examined cardiac troponin (cTn) testing ordered by GPs, comparing the incidence of acute coronary syndrome (ACS) with a similar cohort who received cTn testing in hospitals. Most patients undergoing GP-initiated cTn testing had typical symptoms of ACS and risk factors indicating intermediate or high ACS risk. One in 25 patients were admitted to hospital with ACS within 30 days of GP-initiated cTn testing, approximating the 30-day event rate for intermediate risk patients presenting to hospital. We conclude that GPs should maintain a high threshold for requesting cTn, and should promptly refer patients to hospital when clinical features suggest ACS.
