Doctors measure your cardiac troponin levels to help detect whether you’re experiencing a heart attack. A troponin test can also help doctors find the best treatment sooner.

Previously, doctors used other blood tests (like the CPK isoenzymes test[1]) to detect a heart attack[2]. But they aren’t always the optimal test because they aren’t sensitive enough to detect every attack. Smaller heart attacks leave no trace on these blood tests. The other tests also measure substances that aren’t specific enough to the heart muscle.
