Information about strokes

In a stroke, a blocked cerebral artery causes the brain tissue to be deprived of blood and oxygen. As a result, some of the brain tissue becomes necrotic, and a stroke occurs. Up to 40% of all strokes are caused by atrial fibrillation, an irregular heartbeat that can lead to blood clots. During atrial fibrillation, the heart beats irregularly instead of beating effectively to move blood into the ventricles. If a clot breaks off, enters the bloodstream and lodges in an artery leading to the brain, a stroke results.

Consequences of a stroke

Every sixth of us will suffer from a stroke before the age of 75, of which around 20% will be in the working age. The consequences of a stroke are serious: 1/3 will die, 1/3 will become disabled, 1/3 will go back to normal life. By detecting and treating arrhythmia, such as atrial fibrillation, before severe complications occur, 2/3 of strokes caused by atrial fibrillation could be prevented.

The best way to prevent a stroke is to minimise the risk factors

Monitor your heart rhythm regularly, and seek medical attention if needed in order to get a comprehensive treatment plan for atrial fibrillation  

Check your blood pressure regularly. If necessary, seek medical attention in order to get help to lower and control the blood pressure. 

Exercise regularly 

Check your cholesterol levels. If necessary, seek medical attention in order to get a plan to lower the cholesterol levels 

Quit smoking
