Blood Protein Not Effective as Predictor of Stroke

by Jodee on October 22, 2009

The presence of a protein found in the blood indicates that a person is at risk for a heart attack, but is not a good way to predict the likelihood they will have a stroke. High levels of C-reactive protein (CRP), a marker for inflammation, may indicate that a heart attack is likely, but the same doesn’t hold true when it comes to predicting the likelihood of a stroke.

Researchers followed 2,240 people in New York. All of them were over the age of 40 and stroke free. The study tracked them for eight years. During that time, participants with a CRP level higher than 3 mg/L of blood were 70 percent more likely to have a heart attack and (at a 55 percent higher risk of dying as a result) than those people who had a CRP level of 1 mg/L or less.
