What is atrial fibrilation and how is it linked to strokes?

A study published in New England Journal of Medicine revealed that atrial fibrillation may increase the risk of having a stroke. The study was conducted on  2,580 participants, 10 percent of those having  subclinical atrial fibrillation. After three months it was discovered that the subjects belonging to the former group   were 2.5 times more prone to suffer from strokes and other such diseases that require emergency treatment. 

But what is atrial fibrillation?

Many of us probably felt sometimes heart palpitations, but overlooked it as nothing important. Although it doesn't causes any real symptoms, such things as heart palpitations, or a pain in the chest can be associated with atrial fibrillation.

Atrial fibrillation or AF happens when the upper two chambers of the heart also known as the atria, beat irregularly fast  . This can lead to situations where the heart is unable to provide normal blood flow and oxygen delivery to the rest of the body.  That's why AF patients may complain about having problems with breathing ,especially when exercising or doing any other kind of physical effort.
AF can lead to strokes, depending on the age and condition of the person ,since it may favor the apparition of blood clots.

Atrial fibrillation may be caused by a number of different things such as :

  • High blood pressure
  • Different heart diseases such as  congenital heart disease, mitral stenosis, coronary artery disease.
  • A previous heart surgery
  • Diseases of the lung
  • Excessive consumption of alcohol
  • Intoxication with  carbon monoxide
If you think you may have atrial fibrillation you may easily check this with an  electrocardiogram or EKG test. It's highly recommended to take this test if you experienced the following symptoms:
  •          heart palpitations
  •          chest pains
  •          fainting
  •          dizziness
  •          breathing problems
  •          intolerance to exercise.
There are a number of different treatments for AF, among them listing the intake of an anticoagulant, to prevent the apparition of blood clots.

  2. There are many drugs to counter possible strokes while under Atrial Fibrillation like Warfarin and Pradaxa. But before taking any of these drugs, it’s better to ask your doctor about the risks of these drugs.
    Warfarin is an anti-coagulant but requires frequent blood tests to monitor any blood clots. The Pradaxa on the other hand is a more effective anti-coagulant; however, the risk is higher because while under this medication the effects of this drug cannot be reversed. This may cause excessive bleeding internally or externally when injured. This can be evidenced by a number of Pradaxa lawsuit that were filed against its manufacturers. So be cautious about choosing the right remedy for your Atrial Fibrillation.
