Final answer:
Atrial fibrillation does increase the risk of a CVA or stroke due to the potential formation of blood clots that can travel to the brain.
Step-by-step explanation:
True, atrial fibrillation increases the risk of CVA (cerebrovascular accident), also known as a stroke. Atrial fibrillation is a condition characterized by an irregular and often rapid heart rate that can lead to poor blood flow. As ventricles may still pump blood, immediate life danger isn't always present, but this irregular heartbeat can lead to the formation of blood clots, which can travel from the heart to the brain, resulting in a CVA. In cases of heart failure, as with Ahaya, the risk of conditions like deep vein thrombosis (DVT) is also increased due to suboptimal blood movement through the cardiovascular system, which can likewise result in blood clots.
