Atrial fibrillation has a high incidence in China, especially in elderly people of advanced age, and is one of the most common clinical arrhythmias. Many patients with atrial fibrillation do not have particularly serious clinical symptoms, but once they have atrial fibrillation, they should pay high attention to avoid the risk of recurrent attacks, heart failure and embolism of the body circulation. What should people suffering from atrial fibrillation usually pay attention to? 1, healthy eating habits First of all, a healthy diet refers to: low cholesterol, low fat, low sugar, low salt, more vegetables and fruits and other clear talk and low-calorie meals. Limit or avoid taking substances containing caffeine such as strong tea, cola, coffee, etc. 2, control the healthy weight Control the appropriate weight means: body mass index (BMI) control below 25, will greatly reduce the risk of cardiovascular disease and metabolic syndrome. 3, appropriate physical exercise Regular physical activity is conducive to the prevention of atrial fibrillation, the so-called regular and appropriate exercise means: about 5 times a week, each time half an hour of aerobic exercise, beneficial to health. Brisk walking, jogging are relatively good exercise. 4, strict smoking and alcohol cessation Some studies have shown that smoking is not only a clear risk factor for coronary heart disease and lung disease, but also a risk factor for atrial fibrillation, and the risk of atrial fibrillation in smokers is two times higher than in non-smokers. Alcohol consumption can also increase the risk of atrial fibrillation, so quitting smoking and alcohol is very important for the prevention of atrial fibrillation. 5, keep a calm mind Keep a calm mind and cheerful mood is also important to prevent atrial fibrillation. Excessive stress and prolonged anxiety and depression can lead to or induce arrhythmias. 6, control risk factors There are many risk factors that trigger atrial fibrillation, such as: hypertension, coronary heart disease, heart failure, heart valve disease, diabetes, advanced age and so on. For controllable factors, actively control, such as hypertension, hyperglycemia, coronary heart disease, heart failure and other comorbidities. Actively medicate to prevent disease recurrence and deterioration. 7, regular physical examinations Regular physical examinations, especially electrocardiograms, often check their pulse and heart rate, keep track of their own heart rate and rhythm changes, in order to have a good understanding of their own physical condition, try to prevent disease before it happens.
