Causes of atrial fibrillation

The causes of AF include structural abnormalities of the heart, heart disease, aging, smoking, alcohol consumption, sleep apnea hypopnea syndrome, genetic factors and other diseases. The main causes of AF include the following: 1. Structural abnormalities of the heart: atrial enlargement, atrial myocardial fibrosis, etc. These structural abnormalities may lead to changes in atrial electrophysiological characteristics and increase the risk of atrial fibrillation. 2. Heart disease: such as coronary heart disease, hypertensive heart disease, cardiomyopathy, heart failure, etc., these diseases may affect the normal function of the heart, leading to the occurrence of atrial fibrillation. 3. Other factors: Age: The incidence of atrial fibrillation increases with age. Smoking: Smoking can increase the risk of atrial fibrillation. Alcohol: Excessive alcohol consumption may lead to the occurrence of atrial fibrillation. Sleep apnea hypopnea syndrome: This is a common sleep disorder that can lead to intermittent hypoxia and sympathetic excitation, increasing the risk of atrial fibrillation. Genetic factors: certain genetic mutations or familial atrial fibrillation may be associated with the occurrence of atrial fibrillation. Other diseases: hyperthyroidism, chronic obstructive pulmonary disease, etc., may also increase the risk of atrial fibrillation. It should be noted that the treatment of atrial fibrillation should be individualized according to specific conditions, including drug therapy, cardioversion, catheter radiofrequency ablation, etc. At the same time, for high-risk groups of atrial fibrillation, relevant risk factors should be actively controlled, such as smoking cessation, blood pressure control, treatment of sleep apnea hypopnea syndrome, etc., to prevent the occurrence of atrial fibrillation. If symptoms associated with atrial fibrillation occur, seek medical attention promptly for accurate diagnosis and treatment.
