Can atrial fibrillation be cured? Many patients often ask doctors this question, and the answer is affirmative. With the development of minimally invasive interventional treatment techniques, some patients with atrial fibrillation have been cured after radiofrequency ablation treatment and have not experienced any recurrence. As for which atrial fibrillation cases are suitable for radiofrequency ablation treatment, I suggest that if the atrial fibrillation recurs repeatedly and the symptoms are quite apparent, and the effect of medication is not ideal, one should consult a specialist cardiologist to see if radiofrequency ablation treatment is appropriate.

Can atrial fibrillation be completely cured?

Regarding whether atrial fibrillation can be completely cured, it essentially depends on the definition of being completely cured. If the criterion is complete cessation of medication, then many patients cannot achieve this. However, if the standard is conversion of atrial fibrillation back to normal sinus rhythm, then it is achievable for many patients, such as those with paroxysmal atrial fibrillation, who suffer from recurrent episodes and do not respond well to medication. In such cases, radiofrequency ablation might be attempted, and there is a high likelihood that after the treatment, the rhythm will convert to sinus rhythm. In this sense, some people can be considered cured. However, whether anticoagulation therapy can be discontinued depends on their thromboembolic risk score. This means that even if atrial fibrillation converts to sinus rhythm after radiofrequency ablation, some patients still need long-term anticoagulant medication. Therefore, from the perspective of discontinuing medication, such patients with atrial fibrillation are not considered cured.

Can atrial fibrillation cause cerebral infarction?

Patients with chronic atrial fibrillation have a relatively high incidence rate of embolism. For instance, those with a history of embolism, valvular disease, hypertension, diabetes, elderly patients, left atrial enlargement, and coronary artery disease are at increased risk of embolism. Atrial fibrillation is an independent risk factor for stroke. As age increases, the incidence of stroke in patients with atrial fibrillation also increases annually; atrial fibrillation doubles the mortality rate of stroke and significantly increases the disability rate. At the same time, atrial fibrillation also significantly increases the risk of recurrent stroke. Studies show that the incidence of stroke within the first year after a stroke is 6.92% in patients with atrial fibrillation, compared to 4.7% in those without atrial fibrillation. Therefore, anticoagulation therapy is the primary strategy for managing atrial fibrillation.

Can atrial fibrillation cause chest pain?

During an episode of atrial fibrillation, it is possible for symptoms such as chest pain to occur. Common symptoms of atrial fibrillation include palpitations, chest tightness, and shortness of breath or difficulty breathing. However, during a flare-up of atrial fibrillation, if the heart rate significantly increases, it can lead to chest pain symptoms. This is because when atrial fibrillation occurs and the heart rate significantly increases, it results in a marked shortening of the ventricular diastolic filling period. This reduces the blood volume during the diastolic filling period, further affecting the heart's pumping during the systole, leading to myocardial ischemia and causing symptoms similar to those of angina pectoris.

How to diagnose atrial fibrillation?

Atrial fibrillation, abbreviated as AF, refers to rapid and irregular beating of the atrial chambers of the heart. How should one be examined after being diagnosed with atrial fibrillation? Generally, the examination for atrial fibrillation involves the following aspects: First, blood tests, such as thyroid function tests, to see if there is hyperthyroidism causing the atrial fibrillation. Second, echocardiography. This test can reveal whether there are any heart valve diseases or myocardial diseases that might lead to atrial fibrillation. Third, electrocardiogram (ECG) and Holter monitor. Both ECG and Holter monitoring are effective and non-invasive tests that confirm the diagnosis of atrial fibrillation.

Can atrial fibrillation lead to sudden death?

Atrial fibrillation is a very common arrhythmia in our daily lives, but does it lead to sudden death after its onset? Generally speaking, atrial fibrillation does not cause sudden death, but this does not mean that atrial fibrillation is safe. Atrial fibrillation often poses the following risks: Firstly, it causes symptoms; repeated episodes of atrial fibrillation can cause symptoms such as palpitations and chest tightness in patients. Secondly, it triggers heart failure; acute episodes of atrial fibrillation are often a significant cause of heart failure, which necessitates hospital treatment for many patients. Thirdly, it leads to complications from blood clots, which is one of the most severe yet common complications of atrial fibrillation, leaving sequelae such as weakness in walking or hemiplegia on one side of the body.
