Thirty questions on the two halves of this topic, and the line between them: cardiac biomarkers answer “is there acute cardiac injury or stress?” and lipids answer “what is this patient’s long-term atherosclerotic risk?” Troponin is the marker of choice for injury, and serial values separate injury from infarction. B-type natriuretic peptide reflects stretch, not injury. Creatine kinase is for skeletal muscle. High-sensitivity C-reactive protein refines risk and never diagnoses an acute event. On the lipid side: which components are measured and which calculated, what the apolipoprotein B particles do to the artery wall, why lipoprotein(a) is measured once, and how a risk estimate is built. Every laboratory value comes with the scale that reads it — you are never asked to recall a reference range. The only arithmetic is non-HDL (non-high-density lipoprotein) cholesterol and the Friedewald estimate, the two calculations the material itself asks for.
