The hidden dangers of atrial fibrillation: Why is it a heart disease killer?
Atrial fibrillation (AF) is the most common cardiac arrhythmia in the world, and its prevalence gradually increases with age. However, many people are unaware of the potential dangers of this condition. Atrial fibrillation mistakenly affects the electrophysiological function of the heart, leading to poor blood return and the formation of blood clots. These consequences may further lead to fatal heart disease.
Atrial fibrillation (AF) is a heart disease that kills an average of 80,000 to 200,000 people every year due to atrial fibrillation and its complications.
Causes of atrial fibrillation
Atrial fibrillation has various causes, including hypertension, valvular heart disease, coronary heart disease, cardiomyopathy, hyperthyroidism, etc. Among them, high blood pressure and heart disease are the most common. Changes in the structure and function of the atrium can lead to the occurrence of atrial fibrillation, so early diagnosis is very important.
Symptoms and complications of atrial fibrillation
Although some patients with atrial fibrillation have no symptoms, many may experience symptoms such as palpitations, difficulty breathing, and fatigue. More seriously, atrial fibrillation can lead to potential threats such as heart failure and stroke.
"According to research, about 15% of patients with atrial fibrillation are likely to develop a stroke in the future, and this risk increases dramatically with age."
The connection between atrial fibrillation and stroke
One of the major dangers of atrial fibrillation is that it can significantly increase the risk of stroke. This is because in the case of atrial fibrillation, blood flow may become stagnant in certain areas within the heart, causing blood clots to form. These clots can enter the circulation and eventually reach the brain, causing a stroke.
How to diagnose atrial fibrillation
Diagnosis of atrial fibrillation is relatively simple and can usually be confirmed with an electrocardiogram (ECG) test. An electrocardiogram shows the heart's electrical activity, which can help doctors determine whether fibrillation is present. In addition, 24-hour ECG monitoring or event monitors can be used to capture intermittent atrial fibrillation.
Treatment of atrial fibrillation
There are various treatments for atrial fibrillation, mainly including drug therapy and surgery. Anticoagulant drugs can be used to reduce the risk of stroke, while drugs that control the ventricular rate can help improve symptoms. In some cases, doctors may recommend surgery to electrically cauterize parts of the heart or implant a heart monitoring device.
"Long-term management of atrial fibrillation includes regular checkups and control of risk factors, such as monitoring of high blood pressure and cholesterol levels."
Future challenges and prospects
Despite advances in treatments for atrial fibrillation, many patients remain at significant risk for heart disease. Complications associated with atrial fibrillation and their high incidence pose a global public health challenge. Therefore, strengthening publicity, education and early screening for atrial fibrillation will be crucial.
“We must always be alert to the potential dangers that atrial fibrillation may bring, especially its interaction with other diseases.”
So, how can we improve our understanding of atrial fibrillation to reduce the harm it causes?
