Blood tests, such as troponin and B-type natriuretic peptide
Two biomarkers, two questions
- Two biomarker families that answer different questions:
- Troponin: is there myocardial injury? (not "is there an MI?")
- Natriuretic peptide: is there raised ventricular filling pressure? (not "is there heart failure?")
- *Both are far better at ruling OUT than ruling in. Their negative predictive value is what earns them their place*
