Stroke Study

Wednesday, February 04, 2015

Brain scans following a mild stroke or transient ischemic attack can help identify those at risk of additional brain events. Dr. Edward Hill discusses a study of stroke patients and its conclusions in in todays 60 Second Housecall.

Dr. Hill:

Brain scans taken shortly after a mild stroke can help identify patients at risk of suffering another stroke within three months.

A study was conducted of more than 2,000 people who had CT scans of the brain within 24 hours of suffering a mild, non-disabling stroke or a transient ischemic attack, which are sometimes called mini-strokes.

Of those patients, 40 percent had brain damage due to a lack of sufficient blood flow.

Compared to people who didnt have an interruption in blood flow to part of their brains, the risk of another stroke within 90 days was almost three times higher in those with new brain damage caused by poor blood circulation.

The study, published in the online journal Stroke, also found that the risk of another stroke was more than five times higher in people with previous brain damage from ischemia.

These findings should prompt physicians to be more aggressive in managing patients with transient ischemic attack or non-disabling stroke who are diagnosed with acute ischemia.
