Multicenter Study
Multicenter study of creatine kinase-MB use: effect on chest pain clinical decision making.
To determine whether creatine kinase-MB isomer (CK-MB) levels affect initial physician decisions regarding patients with potential cardiac chest pain. ⋯ For a minority of the patients who had subsequently proven MI, the CK-MB result helped guide disposition decisions. The CK-MB availability did not adversely impact the disposition of the patients who had unstable or new-onset angina.
