Atrial fibrillation

Definition

Atrial fibrillation (AFib) is an irregular and often rapid heart rate that can increase the risk of stroke, heart failure, and other cardiovascular complications. It occurs when the upper chambers of the heart (atria) beat chaotically and out of sync with the lower chambers (ventricles).

1. AFib can lead to blood clots forming in the heart, which may travel to other parts of the body and cause blockages.
2. Common symptoms include palpitations, shortness of breath, fatigue, and dizziness.
3. Risk factors for AFib include high blood pressure, obesity, diabetes, excessive alcohol consumption, and a diet high in sodium.
4. Nutritional interventions for managing AFib include reducing salt intake, increasing consumption of omega-3 fatty acids from fish or supplements, and eating a balanced diet rich in fruits, vegetables, and whole grains.
5. Patients with AFib are often prescribed anticoagulant medications to prevent stroke.
