Study Notes
Biomarker Tests and Precision Medicine
- Biomarker tests guide therapy selection by analyzing individual molecular profiles, enhancing patient treatment outcomes.
- Precision medicine personalizes medical care based on unique patient characteristics, optimizing prevention and treatment efficacy.
- Oncology benefits significantly from precision medicine due to complex cancer genetics involving numerous oncogenes and tumor suppressors.
- Clinical evidence is continuously evolving; treatments initially targeting one biomarker variant may be effective for various molecular targets.
- Advanced biomarker tests allow for more precise disease characterization, including off-label drug use to expand therapeutic options.
- Biomarker tests serve as surrogate endpoints in clinical trials, expediting patient identification for targeted therapies.
- Vemurafenib development exemplifies rapid approval processes, achieving clinical use for BRAF V600E mutation in under six years.
Novel Biomarkers in Cardiac Disease
- High-sensitivity troponin (hs-Tn) enables detection of minor heart muscle damage, outperforming traditional assays in myocardial infarction diagnosis.
- Studies indicate hs-Tn assays improve early myocardial infarction diagnosis and provide prognostic information for coronary artery disease patients.
- Galectin-3 is linked to adverse cardiovascular outcomes; elevated levels correlate with increased heart failure risk and mortality.
- ST2, or soluble ST2, serves as a biomarker tied to inflammation and cardiac remodeling; predicts post-infarction outcomes and prognosis.
- B-type natriuretic peptide (BNP) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) signal increased ventricular stress, assisting in risk stratification for cardiovascular events, even in healthy individuals.
- Growth differentiation factor 15 is involved in inflammation and cellular stress responses, highlighting its potential role in heart disease monitoring.
