What are the risk factors for and prevention of aSAH?
Risk factors for aSAH include high blood pressure, smoking, illicit drug use, and a family history of aneurysm. Prevention of aSAH includes treating high blood pressure with antihypertensive medication, avoiding smoking and illicit drug use, and screening for aneurysms in those with a family history of aneurysm. Additionally, younger age, longer life expectancy, and higher rate of rupture make treatment of unruptured aneurysms more likely to be cost-effective and reduce morbidity and mortality.
