Biomarker Bulletin: March 7, 2011

Biomarker Bulletin is an occasionally recurring update of news focused on biomarkers aggregated at BiomarkerCommons.org. Biomarkers are physical, functional or biochemical indicators of normal physiological or disease processes. The individualization of disease management — personalized medicine — is dependent on developing biomarkers that promote specific clinical domains, including early detection, risk, diagnosis, prognosis and predicted response to therapy.

Abnormal Heart Rate Turbulence May Predict Heart Disease

Additional studies need to be done in order to understand whether this potential biomarker will be a clinically valuable tool.
