Atrial Fibrillation
Atrial Fibrillation - Causes and Risk Factors
The exact cause of atrial fibrillation (AF) remains unknown though there are various medical conditions and individual risk factors that have been associated with AF.
Existing heart conditions:
Those who suffer from heart diseases (such as
coronary artery disease
or
heart valve disease
),
heart failure
or have a history of
heart attack
, have increased risks of AF.
Chronic conditions:
Those with chronic conditions such as sleep apnoea,
diabetes mellitus
or lung problems have a higher risk of AF.
High blood pressure (hypertension):
High blood pressure increases the risk of AF.
Overactive thyroid gland (hyperthyroidism):
Some patients who suffer from thyroid diseases may experience abnormal heart rhythms (arrhythmias) including AF.
Obesity:
Those who are obese are more likely to suffer from AF.
Excessive alcohol or caffeine consumption:
Binge drinking alcohol or consuming to much caffeine can lead to incidences of AF.
Smoking:
Smoking can increase the risk of AF.
Genetics:
Those with a family history of AF are more likely to suffer from the condition.
Age:
Anyone below the age of 50 years old has a 0.1% chance of suffering from AF but this risk increases to 10% for those above the age of 80 years old.
