Which factor is commonly associated with increased stroke risk in patients with atrial fibrillation?

In patients with atrial fibrillation, both physical inactivity and hypertension are significant factors that commonly contribute to an increased risk of stroke.

Physical inactivity leads to a higher risk of various cardiovascular issues, including the development of atrial fibrillation itself. Regular physical activity is crucial for maintaining cardiovascular health, improving blood flow, and reducing the risk of blood clots, which can lead to strokes in individuals with atrial fibrillation.

Hypertension, or high blood pressure, is another substantial risk factor for stroke among patients with atrial fibrillation. It can cause damage to blood vessels and increase the likelihood of clot formation, especially in the presence of atrial fibrillation due to the irregular heart rhythm which may lead to pooling of blood in the heart chambers. This pooling can create conditions favorable to thrombus formation, raising the risk of embolic stroke.

Given that both factors significantly influence stroke risk in the context of atrial fibrillation, the choice indicating both physical inactivity and hypertension highlights the multifaceted nature of risk. Addressing both lifestyle factors and managing blood pressure are essential components in stroke prevention strategies for patients with atrial fibrillation.
