ASC Stroke Prevention & Risk Management

Question 1

What is the most common modifiable risk factor for stroke?

Accepted Answer

Hypertension.

Answer

Hypertension, or high blood pressure, is widely recognized as the most common modifiable risk factor for stroke. Chronically elevated blood pressure damages blood vessels throughout the body, including those supplying the brain, making them more prone to rupture (hemorrhagic stroke) or blockage (ischemic stroke). Managing hypertension through lifestyle changes and medication significantly reduces stroke risk.

Question 2

Which lifestyle change is most effective in reducing stroke risk?

Accepted Answer

Quitting smoking.

Answer

Quitting smoking is one of the most impactful lifestyle changes for reducing stroke risk. Smoking significantly damages blood vessels, increases blood pressure, makes blood more prone to clotting, and reduces the amount of oxygen in the blood. Cessation rapidly lowers these risks, improving cardiovascular health and decreasing the likelihood of both ischemic and hemorrhagic strokes.

Question 3

What is the role of antiplatelet therapy in stroke prevention?

Accepted Answer

Prevent clot formation.

Answer

Antiplatelet therapy, commonly involving medications like aspirin, works by inhibiting the aggregation of platelets, which are blood cells involved in clotting. By preventing platelets from sticking together and forming clots, these drugs reduce the risk of blockages in blood vessels that can lead to ischemic strokes. This therapy is a cornerstone of secondary stroke prevention for individuals at risk.

Question 4

Which condition is a major contributor to stroke risk and often goes undetected?

Accepted Answer

Atrial fibrillation.

Answer

Atrial fibrillation (AFib) is an irregular and often rapid heart rate that can cause blood to pool and form clots in the heart's upper chambers. These clots can then travel to the brain, causing an ischemic stroke. AFib is a major contributor to stroke risk and often goes undetected because it can be asymptomatic, making screening and early diagnosis crucial.

Question 5

Why is diabetes considered a risk factor for stroke?

Accepted Answer

It increases blood vessel damage.

Answer

Diabetes is a significant risk factor for stroke because high blood sugar levels over time damage blood vessels throughout the body, a condition known as atherosclerosis. This damage makes blood vessels narrower, harder, and more prone to clot formation, increasing the risk of ischemic stroke. Diabetes also often coexists with other stroke risk factors like hypertension and high cholesterol.
