Who is susceptible to atrial fibrillation?

Atrial fibrillation causes palpitations and arrhythmias that can end quickly and go away on their own without treatment, but if the heart rate is too fast, emergency care is needed to prevent the risk of stroke and heart attack.

1. What is atrial fibrillation?

Atrial fibrillation is a cardiac arrhythmia that accounts for approximately one-third of all common clinical cardiac arrhythmias. Atrial fibrillation is an irregular heartbeat, especially in the atria. Normally, our heart beats very regularly, with pulses, impulses from the sinus node through the atrioventricular node and then down to the ventricles in a very regular and sequential manner.
This helps the heart beat evenly from 60 to 100 cycles/minute. Atrial fibrillation occurs when the heart is no longer beating as evenly as it should. Conduction through each sinus node has been deleted, replaced by impulses in the atrial region, causing arrhythmias, irregular heartbeat, causing asynchrony between the atria and ventricles.

2. People at high risk for atrial fibrillation

Age over 60 years: about 1% of AF cases in patients <60 years of age, while up to 12% of those aged 75-84 years and even more than one-third of patients 80 years of age and older have atrial fibrillation. Hypertension Coronary artery disease Heart failure Heart valve disease History of open heart surgery Congenital heart disease Sleep apnea Thyroid disease Diabetes

Chronic lung disease Alcohol abuse/stimulant use Infections/severe medical conditions Atrial fibrillation is often associated with the above conditions, so people with medical conditions or people over 60 years of age should proactively go for annual health check-ups to screen for early atrial fibrillation.

3. Technique of occlusion of the left atrium with instruments at Vinmec Central Park

About 90% of strokes in patients with atrial fibrillation without valvular disease are caused by a blood clot that forms in the left atrium, which then enters the great circulation, causing dangerous thromboembolic complications. In the past, the solution for patients with atrial fibrillation was to use anticoagulants (to reduce the risk of stroke). However, the use of anticoagulants in patients with chronic atrial fibrillation has many limitations due to frequent blood tests and drug interactions with diet and other drugs. due to an increased risk of bleeding.
Therefore, the optimal solution for the patient is to block the atrial appendage to prevent blood from entering the atrial appendage. Instrumental left atrial appendage occlusion to prevent thromboembolic events in patients with atrial fibrillation is a modern technique performed at Vinmec Central Park. This technique applies to patients with atrial fibrillation who cannot use long-term anticoagulation to prevent complications caused by atrial fibrillation:
Patient is intolerant of oral anticoagulants. The patient has a history of bleeding due to previous anticoagulation. The patient was unable to comply with oral anticoagulants. Pregnant patients cannot use oral anticoagulants. The patient had a recurrent cerebrovascular accident due to left atrial thrombosis despite being on anticoagulation with adequate doses.

Vinmec Central Park International General Hospital with a team of experienced doctors and nurses, trained in the following specialties at home and abroad combined with modern facilities, especially:
GS.TS.BS Vo Thanh Nhan - Director of Cardiology Center, Vinmec Central Park International General Hospital, is the first expert in Vietnam on percutaneous aortic valve replacement (TAVI). At the forefront of implementing new, intensive cardiovascular techniques: MitraClip, Stent Graft.
The hospital is equipped with Hybrid Operating Room and DSA System, 2 modern angiography systems Discovery IGS 730 of GE and Allura Xper FD20 of Philips for a successful rate of left atrial appendage occlusion by instruments over 90%.
