Who is at the highest risk for a hemorrhagic stroke?

The individual at the highest risk for a hemorrhagic stroke is the 88-year-old male with uncontrolled hypertension and a history of brain aneurysm repair. This is due to several critical factors associated with his health status.

Uncontrolled hypertension is a significant risk factor for hemorrhagic stroke because it contributes to the weakening of blood vessels over time, making them more susceptible to rupture. Elevated blood pressure can cause stress on the vessel walls, increasing the likelihood of bleeding in the brain.

Additionally, having a history of brain aneurysm repair places this individual at a greater risk. Even after repair, there can be residual weaknesses or complications that may predispose him to future hemorrhagic events. Aneurysms, especially if they were ruptured in the past or not fully resolved, can lead to rebleeding or the formation of new aneurysms.

The combination of these two factors—uncontrolled hypertension and a past history of aneurysmatic changes—invalidates the relative safety of other conditions presented in the other options, making this individual particularly vulnerable to a hemorrhagic stroke.

In summary, the presence of uncontrolled hypertension, coupled with a medical history indicating previous cerebral vascular issues, clearly establishes the heightened risk of hemorrhagic stroke in this
