Researchers identify new protein markers that may improve understanding of heart disease
Date:3/30/2014

ive protein, one of the most well-known and studied inflammatory markers shown to be associated with cardiovascular disease, GlycA and GlycB are acute phase proteins with plasma concentrations that increase or decrease in response to changes in the levels of inflammation throughout the body.

This is one of the first studies ever to evaluate the association of GlycA and GlycB to cardiovascular disease. In this study, almost 3,000 patients who underwent heart catheterization to determine the presence of coronary artery disease with a minimum of five years of follow-up were evaluated.

Of the 48 percent of heart patients who died, suffered a heart attack, stroke, or heart failure during follow-up, the majority had significantly higher baseline levels of GlycA and GlycB. Specifically, those with levels in the top 25 percent were more than 30 percent more likely to have an adverse cardiovascular event compared to those with levels in the lowest 25 percent, even after other risk factors were taken into account.

"The next step will be to determine how GycA and GlycB correlate with, or are independent of, other common inflammatory markers like C-reactive protein," said Dr. Muhlestein.
