Need more data: If one exercises for 9 minutes or more on a standard bruce protocol stress test, even if one has known coronary disease, the prognosis is excellent. However, decisions concerning further testing, such as a stress echo test or an angiogram, take into consideration the presence or absence of angina (chest pain) during the test, the amount of abnormality on the ekg during the test and other factors.
