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.Question 12Select one:a.if only W, X and Y are correctb.if only W and Y are correctc.if only X and Z are correctd.if only Z is correcte.if all are correct
Solution
The correct answer is e. All of the options (W, X, Y, Z) are correct.
Here's why:
W. Atrial fibrillation: This is a heart condition that increases the risk of clots forming in the heart. These clots can then travel to the brain, causing a stroke.
X. Atherosclerosis of the carotid arteries: This condition involves the hardening and narrowing of the carotid arteries (the main blood vessels supplying the brain). This can reduce blood flow to the brain or cause a clot to form, which can lead to a stroke.
Y. A metastatic tumour 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, increasing the risk of a stroke. Hypertension (high blood pressure) can weaken blood vessels, making them more likely to burst or clog. Smoking can also damage blood vessels and increase the risk of clots.
