Scientists have discovered new biomarkers for stroke and coronary heart disease (CHD) in postmenopausal women.
Research published in BioMed Central's open access journal Genome Medicine found that beta-2 microglobulin (B2M) levels were significantly elevated in postmenopausal women with CHD, and insulin-like growth factor binding protein 4 (IGFBP4) was strongly associated with stroke.
Ross Prentice, from the Fred Hutchinson Cancer Research Centre, Seattle, USA, worked with a team of researchers to carry out proteomic analyses on samples from 800 women who developed CHD, 800 who developed stroke and a group of matched controls. He said, "We contrasted pools formed by equal plasma volumes from 100 cases or from 100 pair-matched controls, with eight such pool pairs for each of the study diseases. The two novel markers we identified, B2M and IGFBP4, have the potential to help elucidate hormone therapy effects on the cardiovascular diseases as observed in the WHI randomized controlled trials".
