Atrial fibrillation: stroke prevention treatment in patients with atrial fibrillation

The article is consulted professionally by Prof. TS.BS. Vo Thanh Nhan – Director of Cardiovascular Center, Share99 Central Park International Health Hub.

Atrial fibrillation is the most common arrhythmia today and has an increased incidence with age. About 4% of atrial fibrillation occurs in < 60 trong khi đó có tới > patients aged 8% of patients aged 80 years and older with atrial fibrillation.

1. What is atrial fibrillation?

Atrial fibrillation is an abnormal process of formation and spread of electrical impulses of the heart. When the impulse does not come from the sinus node but instead comes from various positions in the two atrium chambers, it leads to constant atrial muscle irritation, and as a result the heart acts in a state of vibration rather than syncic and rhythmic contraction. This condition is called atrial fibrillation.

In atrial fibrillation, electrical impulses form very quickly (usually > 300 times per minute) and are uneven. The two atrium chambers no longer contract rhythmically but "vibrate" so the blood pump is ineffective. In addition to disrupting muscle contraction in the atrium, if these abnormally fast impulses are transmitted down the atrium, it will cause similar phenomena: contractile disorders in the atrium, which causes the heart not to pump blood effectively, can cause hypotension, even life-threatening.

2. Signs of atrial fibrillation

People with atrial fibrillation may have no symptoms, others find it very uncomfortable. The common symptom is that you feel like the heart beats very quickly (drumming the chest), shortness of breath, feeling short of breath. Dizziness, sweating and chest pain can also occur, especially when the frequency is very fast.

When atrial fibrillation is not well controlled, the heart often has to beat very quickly, which will dilate the heart and ineffectively excitation. This is a cause of hemolysis heart failure. It can cause shortness of breath, feelings of fatigue, decreased ability to physical activity and edema.

3. Causes of atrial fibrillation

There are factors that make atrial fibrillation easy to appear but in many cases the cause is not found.

Atrial fibrillation is common in people with coronary artery disease, hypertension. Atrial fibrillation is also common in patients with heart valve disease (openness, mitral valve stenosis), myocarditis, pericarditis, or in patients after heart surgery. Sometimes it can be seen in people with congenital heart disease or hemolytic.

Atrial fibrillation is sometimes seen in people with acute or chronic lung disease. Older people are more likely to have atrial fibrillation than young people. Diabetes, alcoholism or drugs are also factors that increase the risk of atrial fibrillation.

4. Targets for the treatment of atrial fibrillation

Treatment of atrial fibrillation aims at 2 main objectives:

  • Switch back to normal sinus rhythm or control the beat of the mind:

For cases of atrial fibrillation or anky tympaic fibrillation that can be treated with drugs, electric shock … to help shift the rhythm and maintain a normal sinus rhythm.

Interventional treatments (exploration, electrolysmic myocardial combustion) are new methods that help to shift the rhythm but not very high success rates are at risk of recurrence and require modern and high-tech equipment.

  • Prevention of complications caused by atrial fibrillation:

Due to ineffective contractions, atrial fibrillation easily causes the formation of blood clots in the attic chamber, blood clots can move along the bloodstream throughout the body and cause embolitis, especially brain vessels that cause a stroke (atrial fibrillation increases the risk of stroke 5 times).

For the prevention of blood clot formation, patients with atrial fibrillation are assessed for risk to prescribe anti-freezing drugs or apply modern intervention techniques.

5. Technique of left tympaa with tools at Share99

Cardiovascular intervention at International General Health Hub

More than 90% of cases of thromboembolysis form of left urinary inlet origin, after which the blood clot enters the circulation causing dangerous embolic complications.

A tympaa is inlet to prevent thromboembolysis in which thrombosis is inlet in patients at risk but cannot be used long-term anti-freezing drugs or have contrained contrainceptes with anti-freezing drugs, namely:

  • Patients with oral anti-freezing drug intolerance.
  • Patients with a history of bleeding due to previous anti-freezing.
  • Patients cannot adhere to oral anti-freezing medications.
  • Patients who plan to become pregnant cannot use oral anti-freezing drugs.
  • Patients with recurrent cerebral vascular events due to left atrial thrombosis although anti-freezing drugs are still taking doses.

Left atrial seal with a tool to prevent embolization in atrial fibrillation patients is a modern technique that has been implemented at Share99. Share99 International Health Hub with a team of experienced, professionally trained doctors at home and abroad combined with modern facilities is one of the perfect options for customers.

The hospital is equipped with Hybrid Operating Room and DSA System, 2 modern systems Discovery IGS 730 of GE and Allura Xper FD20 of Philips for a rate of left atrial urination with a successful instrument over 90%.

In April &may 2021, when you need to see and treat cardiovascular diseases at Share99 Times City International Health Hub, customers will enjoy double incentives:

– Free specialized examination and 50% discount on many cardiovascular examination packages such as:

+ Basic cardiovascular screening package

+ Hypertension examination package

+ Heart failure examination package

+ Comprehensive cardiovascular examination package

– 50% discount for customers who are prescribed post-examination treatment. The program applies limited to the technique corresponding to each hospital and for customers to perform this treatment technique for the first time at Share99.
