Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following, if left untreated, can lead to an ischemic stroke?
A
Atrial fibrillation
B
Arteriovenous malformation (AVM)
C
Ruptured cerebral arteries
D
Cerebral aneurysm
Explanation: 

Detailed explanation-1: -Untreated atrial fibrillation puts you at a higher risk for stroke and heart failure. People with atrial fibrillation have 3 to 5 times greater risk for ischemic stroke. During Afib, the atria contract chaotically. Because the atria aren’t moving blood properly, blood pools and gets stuck in the grooves of the heart.

Detailed explanation-2: -[3] The risk of stroke in patients with AF has been estimated as between 1% and 20% annually. [4, 5] In the United States, this arrhythmia may be responsible for >70, 000 ischemic strokes each year representing 10%–12% of all ischemic strokes.

Detailed explanation-3: -Heart failure If your atrial fibrillation is persistent, it may start to weaken your heart. In extreme cases, it can lead to heart failure, as your heart is unable to pump blood around your body efficiently.
