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.
A significant share of 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.
Call the emergency response center immediately, if you or someone with you exhibit any of the signs of a stroke mentioned below.
Every sixth person will suffer from a stroke before the age of 75. About 20% of them are still in the working age. The consequences of a stroke are always very grave. A stroke is also always a big tragedy and cause of concern for everyone involved. By detecting and treating arrhythmia – such as atrial fibrillation – before severe complications occur, 2/3 of strokes could be prevented.
