Animation: Troponin and Diagnosis of MI

Click to watch video

Only 10% of patients admitted for chest pain and shortness of breath have chest pain related to ischemia, and accurate diagnosis is critical for triage. Troponin is the preferred blood test to aid in the diagnosis of myocardial infarction (MI), due to specificity of myocardial damage. Troponins are a family of proteins that help the heart muscle contract. During an MI, myocardial necrosis due to ischemia stimulates the release of cardiac troponin into the bloodstream.

In this animated video, you’ll learn more about cardiac troponins, testing, and guidelines, and the role of this critical biomarker for earlier MI diagnosis.
