Smoking boosts aneurysm risk

Women who smoke are eight times more likely to have an abdominal aortic aneurysm (AAA) repair or rupture than women who have never smoked, US research suggests.

The researchers assessed the potential risk factors for rupture of AAA in 161,808 postmenopausal women.

Smokers were eight times more likely to suffer a rupture than women who had never smoked, and four times more likely to suffer a rupture compared with women who had quit smoking. Additionally, they found that HRT provided protection from AAA events.
