Hypertension is a major risk factor for Subarachnoid haemorrhage |

Dear Ask The Doctor: Can hypertensive heart disease cause a subarachnoid hemorrage or vice versa? Dear Sarah: Subarachnoid haemorrhage (SAH) is bleeding into the subarachnoid space between the pial and arachnoid membranes surrounding the brain. It often occurs secondary to rupture of an aneurysm, which is an abnormal local dilatation in the wall of a blood vessel, usually an artery, due to a defect in the wall, disease, or injury. Hypertension is a major risk factor for SAH. Uncontrolled hypertension may cause the defective arterial wall to rupture, leading to catastrophic bleeding. Other risk factors for SAH include; smoking, moderate to heavy alcohol consumption, inherited diseases (Adult polycystic kidney disease, Ehler Danlos syndrome) and a positive family history of SAH. |
