Clinical Significance

Used as a diagnostic aid in risk stratification for myocardial infarction.

Myoglobin is a heme protein found in both cardiac and skeletal muscle. Following myocardial necrosis associated with myocardial infarction (MI), myoglobin is one of the first markers to rise above normal levels, increasing measurably above baseline within 1-3 hours post infarct, peaking at 6-12 hours and returning to baseline within 24?36 hours. In the absence of skeletal muscle trauma or other factors associated with a non-cardiac related increase in circulating myoglobin, myoglobin levels have been used as an early marker for measurement of MI. A number of reports suggest the measurement of myoglobin as a diagnostic aid in risk stratification for myocardial infarction with negative predictive values of up to 100% reported at certain time periods after onset of symptoms.
