Some risk factors for developing atrial fibrillation are similar to those for cardiovascular disease, cancer and stroke:
- Lack of regular exercise - strive for at least 30 minutes, five days a week, or 150 minutes per week.
- Stress - be aware that an underappreciated stress sensation may be present due to home, work, financial matters as well as depression, loss and lack of control.
- Smoking and COPD
- Diabetes - a 50 percent risk reduction is possible with aggressive diet modifications; go plant-based as much as possible.
Other risk factors for developing atrial fibrillation:
- Hyperthyroidism - should always be checked for atrial fibrillation patients.
- Sleep apnea
- Pulmonary emboli
- Illness or surgical procedure
- Heart diseases (valves, conduction system, coronary arteries, pericardium, or muscle)
- Low levels of sodium, potassium, magnesium (diuretics)
- Alcohol abuse - heavy use is a risk; one or two drinks a day is not such a big risk.
- ‘Holiday Heart’ – overeating, binge alcohol, stress
- Heart Failure
Risk factors for having a recurrent episode of atrial fibrillation:
- Same as for developing atrial fibrillation
- Caffeine (coffee, tea, soda, chocolate)
Warfarin and diet – green vegetables which contain unit Vitamin K can affect INR. Don’t avoid green leafy vegetables, but try to be regular in their intake, for example, one to two servings daily.
