Drinking coffee, making love and blowing your nose can considerably increase your odds of having a lethal type of stroke, warned researchers from Netherland. Thousands of people suffer a subarachnoid haemorrhage each year which is most common in the middle-aged, especially in women. This type of stroke is deadly for more than half of victims.
The researchers from at the University Medical Center in Utrecht observed two hundred and fifty patients for three years to identify what triggers ruptures. They examined eight routine activities and functions of the body which are prone to increase the blood pressure abruptly and risk this type of stroke. It happens when a weakened blood vessel surrounding the brain ruptures and injures brain tissue.
When a weakened blood vessel known as brain aneurysm burst then bleeding can happen that can result into brain damage or death. Nearly ten to fifteen percent of victims die prior to reaching hospital and fifty percent die within a month. The study patients were asked if they had drunk coffee, been exercising or blown their nose an hour before the stroke.
They were also asked if they would usually do these activities at this time or if it was a rarity. They found that coffee was guilty for more than one in ten burst brain aneurysms. Whereas people drinking coffee had only one and half times greater risk, it is more frequent than other risk aspects.
Researchers were competent to guess how much each activity increased the risk of the stroke. According to Dr Monique Vlak, a neurologist and lead author of the study all of the triggers induce a sudden and short increase in blood pressure, which seems a potential common cause for aneurysmal rupture.
An abrupt surge in high blood pressure can increase the likelihood of an aneurysm rupturing. But it is very hard to resolve if the triggers identified in this study are certainly linked to the onset of a stroke as they could merely be put down to coincidence, explained Dr Sharlin Ahmed, Research Liaison Officer from The Stroke Association.
The more study is to be carried out to assess whether each of the identified triggers could directly cause an aneurysm to rupture, added Dr Ahmed .The study was published in Stroke, the Journal of the American Heart Association.
