Your Heart's Messengers: What Cardiac Biomarkers Are
When you experience chest pain, every second counts. Your doctor needs to know quickly if your heart muscle is in distress. This is where cardiac biomarkers come in. Think of them as tiny messengers released into your bloodstream when your heart is under stress or has been injured. These are not just any proteins; they are specific substances like troponin and B-type natriuretic peptide (BNP) that provide a clear signal of cardiac trouble. The presence and levels of these biomarkers help doctors determine if a heart attack has occurred, if heart failure is present, or if there is other underlying cardiac damage. They provide a precise, objective measure that complements an electrocardiogram (ECG) and physical exams, transforming a doctor’s suspicion into a definitive diagnosis. It’s a rapid, scientific approach to identifying life-threatening conditions, a key part of the larger Cardiac Biomarkers Market.
