Summary: Several infections have been linked to increased risk of ischemic stroke. The strongest link was found between urinary tract infections, which increased stroke risk by more than three times within 30 days of infection.
Several infections have been identified as possible stroke triggers, with urinary tract infections showing the strongest link with ischemic stroke, according to new research in the American Heart Association’s journal Stroke.
Previous research examined infections as triggers of stroke, but were limited to the correlation of acute infections with ischemic stroke, a type of stroke caused by blocked blood vessels in the brain. This study considered a wider range of infections, and examined connections with two other types of stroke: intracerebral hemorrhage, which is caused by a ruptured blood vessel in the brain, and a type of stroke that results from bleeds in the inner lining of the brain, called subarachnoid hemorrhage.
