Drinking coffee may raise the risk of deadly strokes by 11 percent in millions of people with brain aneurysms, according to a study linking spikes in blood pressure to the rupture of the weakened blood vessels in the brain. Researchers from University Medical Center in Utrecht, the Netherlands, analyzed 250 patients who survived such a stroke and identified eight risk factors tied to the event. They included drinking a cup of coffee, which carried the highest risk, having sex, physical exercise, nose blowing, straining to defecate, drinking cola and being startled or angry.
