A common risk factor for thrombotic stroke is:

High blood pressure, also known as hypertension, is a well-established risk factor for thrombotic stroke. Thrombotic strokes occur when a blood clot (thrombus) forms in an artery that supplies blood to the brain, leading to a reduction or complete blockage of blood flow. Chronic high blood pressure can damage blood vessels over time, making them more susceptible to plaque buildup, which can contribute to clot formation.

When the blood vessels are narrowed or blocked due to plaque and injury caused by persistent high blood pressure, the risk of forming a thrombus increases significantly. Managing blood pressure through lifestyle changes and medication is crucial in reducing the risk of thrombotic strokes, making it a primary focus in stroke prevention strategies.

In contrast, while high sodium intake may contribute to high blood pressure, it is not directly classified as a risk factor for thrombotic stroke on its own. Blunt force trauma to the head is generally more associated with hemorrhagic strokes, and chronic obstructive pulmonary disease does not have a direct link to thrombotic strokes in the same comprehensive manner as high blood pressure does.
