Main causes and risk factors
Atrial fibrillation (AFib) is a common heart disease that causes an irregular and often fast heartbeat. The biggest cause of AFib is high blood pressure. When blood pressure stays high for a long time, it puts a constant strain on the heart. This pressure affects the atria, which are the upper chambers of the heart. Over time, this causes structural changes and disrupts normal electrical signals.
Age is another important factor. As people age, they become more likely to have heart rhythm problems. People over the age of 60 have a higher risk of developing AFib. In addition, other health conditions such as diabetes, obesity and heart disease can also increase the risk.
Lifestyle choices also play an important role. Smoking, lack of exercise, poor diet and excessive alcohol consumption can damage heart health. Stress and sleep disorders such as sleep apnea can also trigger AFib episodes. In some cases, AFib can occur for no apparent reason, but this is less common.
Prevention and long-term care
Prevention of AFib focuses primarily on controlling blood pressure. Regular physical activity helps keep the heart strong. A balanced diet with little salt and healthy fats can improve heart function. Avoiding smoking and limiting alcohol consumption are also important steps.
Doctors may prescribe medication to control heart rate or prevent blood clots. Regular health checks can help detect early symptoms. Prompt treatment reduces serious complications such as stroke.
In conclusion, high blood pressure is the most important cause of AFib. However, the risk can be significantly reduced with a healthy lifestyle and proper care.
