Overview
Numerous risk factors have been found for atrial fibrillation. There are some reversible risk factors such as alcohol drinking and alcohol withdrawal, caffeine, cocaine, stimulant and smoking. Furthermore risk factors such as hypertension, diabetes, obesity and sedentary lifestyle can be considered as reversible conditions that can increase the chance of atrial fibrillation development. On the other hand risk factors such as hypertrophic obstructive cardiomyopathy, heart failure, chronic renal failure and positive familial history have been introduced as irreversible risk factors in atrial fibrillation. There are also conditions that have been recognized as risk factors for ischemic stroke or systemic embolization in patients with non-valvular atrial fibrillation, such as advanced age, impaired left ventricular systolic function, hypertension and diabetes. Male sex, diuretic use and cardiac or thoracic surgery are also among other known risk factors.
Risk Factors
Reversible or Modifiable Underlying Conditions Associated with Atrial Fibrillation
- Alcohol and alcohol withdrawal
- Breath spray which contains alcohol [1]
- Caffeine (coffee or tea)
- Cocaine
- Smoking[2][3]
- Coronary artery bypass graft surgery
- Esophageal surgery [2]
- Hyperthyroidism
- Hypertension[3]
- Diabetes [3]
- Obesity [3]
- Hypomagnesemia[4]
- Hypothermia
- Hypothyroidism
- Hypoxia
- Pericarditis and pericardial disease in general
- Pheochromocytoma
- Pulmonary embolism
- Stimulants
- Sedentary lifestyle [3]
- Sleep apnea [3]
Irreversible Underlying Conditions Associated with Atrial Fibrillation
- Hypertrophic Obstructive Cardiomyopathy [2]
- Heart failure[5]
- Short QT syndrome
- Chronic renal failure[6]
- Ischemia heart disease[2]
- Familial history [7]
Risk Stratification
- Once a patient develops atrial fibrillation, their risk of subsequent events can be assessed using the following scores:
- The risk of bleeding associated with anticoagulation can be assessed using the following score:
Risk factors for Ischemic Stroke or Systemic Embolization in Patients with Non-valvular Atrial Fibrillation
Risk factors and relative risks are tabulated below: [8][9][2]
| Risk Factor | Relative Risk |
| Advanced age (continuous, per decade) | |
| History of hypertension | |
| Heart failure or impaired left ventricular systolic function | |
| Coronary artery disease (CAD) | |
| Diabetes mellitus (DM) | |
| Previous stroke or Transient Ischemic Attack (TIA) |
