<p><b>New page</b></p><div>==Background==<br />
*Creatine kinase MB isoenzyme; historically used as cardiac biomarker<br />
*Largely replaced by [[troponin]] for ACS diagnosis<br />
<br />
==Normal Values==<br />
*Normal: <5 ng/mL (or <5% of total CK)<br />
<br />
==Interpretation==<br />
*Rises 4-6 hours after MI, peaks at 12-24 hours, normalizes in 48-72 hours<br />
*Faster return to normal than troponin makes it useful for detecting reinfarction<br />
*CK-MB:total CK ratio >5% suggests cardiac source<br />
*Largely obsoleted by high-sensitivity troponin for acute MI diagnosis<br />
