Beware of the “silent killer” behind the stroke

Atrial fibrillation is a common arrhythmia disease in the clinic, which is familiar and unfamiliar to many elderly people. The reason why I am familiar with it is that atrial fibrillation is one of the common heart diseases in the elderly, because it is often accompanied by heart failure and stroke, which has caused everyone’s special attention. The reason why it is strange is because many patients are facing the room. The symptoms of tremors are unpredictable, and many times it is not known that atrial fibrillation has arrived.

In daily life, many elderly people will encounter palpitation and palpitations, but many people often do not care. In fact, these symptoms are likely to be early warning signs of atrial fibrillation and need to be vigilant. Due to the early symptoms of atrial fibrillation and the lack of scientific understanding of the symptoms of atrial fibrillation, many times we have not been able to understand the meaning behind these signals, thus delaying the optimal treatment opportunity and leaving irreparable hurt.

So what is atrial fibrillation? Why is the atrial fibrillation “quiet”, but the lethality is so huge?

Atrial fibrillation, as the name implies, is a common cardiovascular disease in the atrium. According to statistics, the incidence of atrial fibrillation is 1% in the overall population; the incidence of atrial fibrillation is about 0.5% in people aged 40-50 years; in the elderly over 80 years old, the incidence of atrial fibrillation can be Up to 8% to 10%. It can be seen that the occurrence of atrial fibrillation is closely related to age. The older the patient, the higher the incidence of atrial fibrillation.

Why does atrial fibrillation cause a stroke?
Our heart has two atriums and two ventricles. In general, the order of normal heartbeats is: atrial contraction, followed by ventricular contraction, and then the atria and ventricles relax together, which is the process of completing a heartbeat. The heartbeat we usually feel is usually the contraction of the ventricle. However, when the heart is “out of control”, the beat is irregular and abnormally fast, it may be a sign of atrial fibrillation. There are many factors that cause atrial fibrillation, including high blood pressure, coronary heart disease, diabetes, chronic lung disease, heart failure, congenital heart disease, and hyperthyroidism. In addition, alcoholism, long-term mental stress, etc. may also induce atrial fibrillation.

The main symptoms of atrial fibrillation are palpitations, shortness of breath, dizziness, and, in severe cases, black sputum and even syncope. However, nearly one-third of atrial fibrillation episodes are asymptomatic, and many people ignore it. Atrial fibrillation is extremely occult, and the harm is multifaceted. Atrial fibrillation increases the risk of stroke by a factor of five, the risk of heart failure by a factor of three, and the risk of dementia and death by a factor of two, seriously threatening the life and health of patients.

About one-fifth of the strokes are caused by atrial fibrillation. Why does atrial fibrillation cause a stroke? This is because the atrial fibrillation patients’ atrium can not contract and relax regularly, which makes the blood easily stagnant in the atrium and coagulate to form a thrombus. After the blood clot is detached, the blood is circulated, and “stagnation” is in various parts of the body. Among them, the probability of “stagnation” in the cerebral blood vessels is the greatest, and the hazard is also the greatest. According to statistics, the mortality caused by atrial fibrillation within a 30-day mortality rate can reach 25%, and the mortality rate within a year can be as high as 50%.

No symptoms are not equal to no harm
Each person has different subjective feelings about the symptoms of atrial fibrillation. Some patients have more clinical manifestations, while others may have no feeling. Some patients feel that the symptoms are mild, but they are considered to be mild and do not affect health and are neglected. The harm of atrial fibrillation does not depend on the severity of the symptoms. The mild symptoms do not mean that the harm is small. No symptoms do not mean no harm. If the onset of atrial fibrillation is not promptly and effectively diagnosed, the patient’s heart will gradually expand, thereby increasing the risk of heart failure and stroke, which can lead to hemiplegia, aphasia, and even death.

So, how should you observe whether you and your people around you have atrial fibrillation in your daily life? The key signals of these six AFs can help you identify early:

1. Feel the heartbeat faster;

2. The pulse strength varies;

3. Feeling chest tightness and shortness of breath after exerting strength;

4. Easy to fatigue and fatigue;

5. Chest tightness, chest pain;

6. Dizziness or fainting.

If these signals appear, you should seek medical advice promptly, conduct professional and systematic examinations, and check the cause early. Older people, especially those with underlying diseases such as hypertension, diabetes, and coronary heart disease, should pay more attention to regular physical examinations, early detection of hidden atrial fibrillation, and early treatment.

Healthy life, stabilize the “out of control” heartbeat
At present, the mechanism of atrial fibrillation is still unclear, but the study found that it is closely related to factors such as sleep and psychology. Therefore, a healthy lifestyle can play a role in preventing atrial fibrillation. We should maintain a good sleep, actively treat basic diseases such as hypertension and hyperglycemia, and control body weight, which can effectively reduce the incidence of atrial fibrillation.

Huge stress, frequent anxiety and excessive anger can increase the probability of atrial fibrillation. Therefore, maintaining a good attitude, broad mind and positive and optimistic attitude towards life is one of the easiest ways to prevent atrial fibrillation.

If you already have atrial fibrillation, you should quit smoking and stop drinking. Limit or avoid drinking tea, coffee, cola, etc. You should be more cautious when taking certain cold medicines. If you are not sure, consult your doctor promptly to avoid taking some ingredients that may cause arrhythmia. Moderate exercise should also be adhered to in life. Full aerobic exercise can enhance heart and lung function and can effectively reduce the risk of atrial fibrillation.
