Understanding atrial fibrillation and how it contributes to silent strokes
Atrial fibrillation (AFib) is a health condition that disrupts the heart’s natural pumping rhythm, causing blood to pool in the atria and increasing the likelihood of clot formation. When these clots travel to the brain, they cause silent strokes, which often occur without noticeable symptoms. Silent strokes can lead to cognitive decline and dementia over time. Therefore, understanding the link between AFib and silent strokes helps with early diagnosis and timely management of complications. Atrial fibrillation Atrial fibrillation is an irregular heart rhythm that occurs when the heart’s upper chambers (atria) quiver instead of contracting properly. This irregularity can lead to blood pooling in the atria, forming clots. A clot breaking loose and reaching the brain can block a blood vessel, leading to a stroke. One should know certain things about Afib. It is one of the most prevalent cardiac arrhythmias, affecting approximately 2-3% of the global population. Its prevalence increases with age, making it more common among older adults. Some individuals may have AFib without experiencing any noticeable symptoms. It is known as “silent AFib,” making it crucial to conduct regular heart monitoring, especially in high-risk groups. Silent strokes Silent strokes, otherwise known as asymptomatic cerebral infarctions, occur without apparent symptoms.
