Question
Which of the following would increase the risk of ischemic stroke?W. Atrial fibrillation.X. Atherosclerosis of the carotid arteries.Y. A metastatic tumour entering the circle of Willis.Z. Hypertension and smoking.
Solution
All of the options listed can increase the risk of an ischemic stroke.
W. Atrial fibrillation: This is a heart condition that involves irregular and often rapid heart rate. It can result in poor blood flow to the body, including the brain. This can lead to the formation of blood clots, which can travel to the brain and cause a stroke.
X. Atherosclerosis of the carotid arteries: This is a condition where the arteries that supply blood to the brain become narrowed due to a buildup of plaque. This can restrict blood flow to the brain and potentially lead to a stroke.
Y. A metastatic tumor entering the circle of Willis: The circle of Willis is a circle of arteries that supply blood to the brain. A tumor in this area could potentially block blood flow, leading to a stroke.
Z. Hypertension and smoking: Both of these factors can damage blood vessels, making them more prone to blockage. This can increase the risk of a stroke.
