Heart disease is among the most widespread illnesses and can present with symptoms such as shortness of breath, dizziness, and heart palpitations, according to the CDC. However, some conditions are barely noticeable.
According to Parade, atrial fibrillation is a common heart rhythm disorder affecting millions of people.
In this condition, the heart beats irregularly, affecting how blood moves through the body.
This makes the disease difficult to detect in time, as many people do not experience clear symptoms. As a result, it can progress without treatment.

Blood flow
The problem arises when blood does not flow normally through the heart.
With atrial fibrillation, blood moves more slowly in the heart’s upper chambers, according to a study published in the Journal of the American Heart Association.
When blood stagnates, clots can form. These can then travel through the bloodstream and reach the brain.
Other heart conditions can also increase the risk, though the underlying mechanisms are not always the same.

What can be done?
Atrial fibrillation significantly increases the risk of stroke and is associated with about 22 percent of cases, according to Stopafib.
In addition, the risk can be up to five times higher than normal, according to a study published in the Journal of the American Heart Association.
Although factors such as age and genetics cannot be changed, lifestyle can play a role.
Exercise, reduced alcohol consumption, and treatment of other conditions can help manage the disorder.
