What is the primary risk factor for a Cerebral Vascular Accident (CVA)?

Hypertension, or high blood pressure, is identified as the primary risk factor for a Cerebral Vascular Accident (CVA), commonly known as a stroke. This condition significantly increases the risk of stroke due to the stress and damage it places on blood vessels throughout the body, particularly in the brain. High blood pressure can lead to the hardening and narrowing of arteries, creating an environment conducive to clot formation or rupture of weakened vessels, ultimately resulting in either an ischemic stroke (from blocked blood flow) or a hemorrhagic stroke (from bleeding in the brain).

In comparison to other factors such as excessive alcohol consumption, high cholesterol, and obesity, while these can also contribute to cardiovascular diseases and an increased risk of stroke, the correlation between hypertension and stroke incidence is well-established and supported by extensive research. Effective management of blood pressure through lifestyle changes and medication can significantly reduce the risk of experiencing a CVA, emphasizing its critical role as a primary risk factor.
