High Troponin Levels

Medically reviewed by Last updated on Dec 2, 2022.

High troponin levels can be a sign of a heart attack or other heart damage. Troponins are muscle proteins, and some are only found in the heart muscle. Damage to the heart causes troponin to be released into the bloodstream. Blood tests check for troponin. Healthcare providers will talk to you about next steps based on your test results. You may need more tests. Your condition may need to be monitored if you are at high risk for a heart attack. Your doctor or other providers can also help you create a plan to improve or maintain your heart health.
