Name a potential cardiovascular risk of uncontrolled hypertension.

Uncontrolled hypertension is a significant risk factor for a variety of cardiovascular conditions, with stroke being one of the most severe consequences. High blood pressure can damage blood vessels, making them more susceptible to rupture or blockage, which can lead to ischemic or hemorrhagic strokes. The increased pressure can cause the walls of the arteries to weaken over time, potentially leading to the formation of blood clots that can obstruct blood flow to the brain.

In addition to stroke, it is worth acknowledging that uncontrolled hypertension can also lead to other serious conditions such as heart failure, arrhythmias, and myocardial infarctions, as it puts continuous strain on the heart and vascular system. However, the direct link between high blood pressure and stroke underscores why selecting stroke as a potential cardiovascular risk makes sense in the context of uncontrolled hypertension.
