Predicting Risk for Recurrent Stroke

Predicting Risk for Recurrent Stroke
People who have just suffered their first ischemic stroke, a blood clot in the brain, often have elevated inflammatory biomarkers in their blood that indicate their likelihood of having another stroke or an increased risk of dying, as per Columbia University Medical Center scientists at NewYork-Presbyterian Hospital.

Reported in the Oct. 23 Archives of Internal Medicine, results of the new study indicate that these inflammatory markers are linked to long-term prognosis after a first stroke, and may help guide clinical care for people who have suffered a first stroke.

A biomarker called lipoprotein-associated phospholipase A2 (Lp-PLA2), which has been FDA-approved to predict the risk of first stroke, was found to be a strong predictor of recurrent stroke risk. Scientists also observed that elevated levels of another biomarker called high-sensitivity C-reactive protein (hs-CRP), a test usually used to predict risk of heart disease, was linked to more severe strokes and an increased risk of mortality.

"A better understanding of biomarkers for stroke risk may lead to the use of prophylactic therapys to reduce risk of people suffering debilitating strokes," said lead author Mitchell S. V. Elkind, M.D., M.S., associate professor of Neurology at Columbia University College of Physicians and Surgeons and neurologist at NewYork-Presbyterian. "For example, statins appear to lower these biomarker levels, so our next step may be to study the clinical benefit of prescribing statins to reduce the risk of stroke in people with elevated biomarkers, and also to treat people who have suffered a stroke so that they do not have another serious event".

The research was conducted by taking blood samples from 467 patients who had just suffered their first ischemic stroke, from the Northern Manhattan Stroke Study, a long-term prospective study among people from the Washington Heights neighborhood in Northern Manhattan and the surrounding area. The ongoing study, which began in 1990, is run by the Neurological Institute of New York at Columbia University Medical Center and NewYork-Presbyterian, located in Washington Heights.

The team of scientists at Columbia and NewYork-Presbyterian also included: Ralph L. Sacco, M.D., M.S.; Wanling Tai, B.S.; Kristen Coates, B.S.; and, Myunghee C. Paik, Ph.D.
