After a myocardial injury, Troponin I levels rise rapidly and are detectable within the hour, but Troponin I levels are not detectable in people who have not suffered a cardiac injury.

Lactate dehydrogenase is present in almost all body tissues but is not specific to heart muscle. ldh isoenzymes are useful in diagnosing cardiac injury. Complete blood count is obtained to review blood counts, and a complete chemistry is obtained to review electrolytes. Creatine kinase levels may rise with skeletal muscle injury, so the creatine kinase isoenzymes are required to detect cardiac injury.

Troponin i-troponin Ilevels rise rapidly and are detectable within 1 hour of myocardial injury. troponin i levels arent detectable in people without cardiac injury. Lactate dehydrogenase is present in almost all body tissues and not specific to heart muscle. IDH isoenzymes are useful in diagnosing cardiac injury. CBC is obtained to review blood counts, and a complete chemistry is obtained to review electrolytes. Because ck levels may rise with skeletal muscle injury, ck isoenzymes are required to detect cardiac injury.
