    Blood tests for the cardiac enzyme creatine phosphokinase MB (CKMB) appear in blood test results within four to six hours after a heart attack and peak within 12 to 24 hours. After two or three days, cardiac enzymes can no longer be detected by blood tests, so these tests are only useful to detect recent heart attacks.
