Smoking and subarachnoid haemorrhage

An enquiry was made into the smoking habits of 199 patients who had survived a subarachnoid haemorrhage (SAH). Information was obtained from 189, giving a 95% response rate. Those with a cerebral aneurysm had on average smoked considerably more cigarettes daily than those with arteriovenous malformations (AVM) or with normal angiographic findings (NAF) whose smoking habits were similar to those of the UK population. SAH due to cerebral aneurysm should be considered another smoking-related disease.
