Coffee, Vigorous Exercise May Trigger Aneurysm Rupture
May 10, 2011 — Dutch researchers have identified and quantified 8 potential trigger factors for intracranial aneurysm rupture, including consumption of coffee or cola, straining for defecation, and vigorous physical activity.
“Reducing caffeine consumption or treating constipated patients with unruptured intracranial aneurysm with laxatives may lower the risk of subarachnoid hemorrhage [SAH],” Monique H. Vlak, MD, of University Medical Center Utrecht, the Netherlands, and colleagues write in the journal Stroke, published online May 5.
However, “We do not advise them to refrain from physical exercise, since this also is an important factor in lowering the risk of other cardiovascular diseases,” she emphasized in comments to Medscape Medical News.
“These factors are not surprising,” said Y. Jonathan Zhang, MD, a neurosurgeon with the Methodist Neurological Institute in Houston, Texas, who was not involved in the study. “They are well-known anecdotes.”
However, he cautioned, that “at most, they may be associated with the aneurysm rupture, but it is very premature to conclude that they actually caused the rupture.”
