Myoglobin is a small protein, and it leaks out of muscle cells soon after injury. Myoglobin concentrations within the blood start to rise within 1-3 hours of a heart attack or other muscle injury, reach their highest values by about 8-12 hours, and generally fall back to normal by about one day after injury occurred.
Myoglobin blood tests may be requested in people with chest pain who are suspected of having had a heart attack, particularly if the electrocardiogram (ECG) does not give clear cut results. (The ECG records the electrical changes in different parts of the heart muscle as it beats; the patterns change when heart muscle is damaged.
When the myoglobin concentration in the blood rises, there has been very recent injury to the heart or other muscle tissue. If myoglobin does not increase at that point, a heart attack is very unlikely, unless the chest pain started more than a day before.
Those experiencing chest pain that is suspected to be due to a heart attack; When there has been severe traumatic injury to skeletal muscle
