Uses and limitations of stress testing in the evaluation of ischemic heart disease.

摘要: The results of stress testing in patients being assessed for coronary artery disease have led to conflicting claims and conclusions. It seems reasonably clear that is considerable predictive value epidemiologic studies; i.e., manifesting or developing a positive exercise test much higher probability subsequently experiencing events (angina pectoris, myocardial infarction, death) than those individuals with normal tests. Moreover, the risk be related degree S-T segment depression. In contrast, despite earlier regarding diagnostic accuracy which single-load tests could predict presence absence ischemic heart individual patients, studies correlating extent angiographically demonstrated not consistently shown either acceptable sensitivity specificity. Although on theoretic grounds it would anticipated...
