Atrial Fibrillation (AFib) is a common heart rhythm disorder where the heart beats irregularly and often rapidly. While AFib itself may not always be life-threatening, it significantly increases the risk of embolic stroke. Understanding this connection helps patients take timely preventive measures.
How atrial fibrillation increases the risk of embolic stroke
How atrial fibrillation increases the risk of embolic stroke lies in abnormal blood flow within the heart. In AFib, the upper chambers (atria) do not contract properly, allowing blood to pool and form clots. These clots can travel to the brain, block a blood vessel, and cause an embolic stroke. AFib-related strokes are often more severe than other types, making early diagnosis and treatment critical.
Warning symptoms of embolic stroke due to AFib
The warning symptoms of embolic stroke due to AFib can appear suddenly. These include weakness or numbness on one side of the body, slurred speech, facial drooping, sudden vision loss, dizziness, or severe headache. Any of these symptoms requires immediate emergency care, as early treatment can reduce long-term disability.
Difference between embolic and ischemic stroke in AFib
Understanding the difference between embolic and ischemic stroke in AFib is important. An embolic stroke occurs when a clot forms elsewhere (usually the heart) and travels to the brain. An ischemic stroke, more broadly, refers to any blockage in a brain artery. In AFib patients, most strokes are embolic in nature, which is why blood-thinning medicines are often prescribed.
Long-term care tips for AFib patients to prevent stroke
Long-term care tips for AFib patients to prevent stroke include taking prescribed anticoagulant medicines regularly, controlling blood pressure and diabetes, avoiding smoking, limiting alcohol, and maintaining a healthy weight. Regular heart rhythm monitoring and follow-ups are essential. Guidance from experienced Cardiac Electrophysiologists in Chennai helps optimise rhythm control and stroke prevention strategies.
