Novel Biomarkers in Cardiovascular Disease: Research Tools or Ready for Personalized Medicine?

In recent years, a wide range of novel biomarkers have been evaluated for different cardiovascular disease states (eg, ischemia, congestion, and physiological stress), and many have shown promising results for the prediction of cardiovascular end points. However, to become useful for clinicians and to allow for personalized medicine, each novel biomarker must fulfill 3 fundamental criteria: (1) it must be easy to measure; (2) it must provide new information; and (3) it must help the clinician to manage patients. Although many biomarkers may be useful for prognostication, very few have been shown to improve the treatment of patients with cardiovascular disease when implemented in a clinical setting.
