Blood levels of CK rise when your muscle or heart cells are injured. Your doctor may request measurement of CK (along with tests for other substances, particularly the CK-MB form) if you have chest pain to see if you may have had a heart attack.
In the first 4 to 6 hours after a heart attack, CK in blood begins to rise. It reaches its highest level after about 18 to 24 hours, and returns to normal in about 2 to 3 days.
The test for CK can also indicate if your other muscles are damaged.
