INTRODUCTION

Atrial fibrillation is a common condition and risk factor for stroke. At age 60 years, the prevalence of atrial fibrillation is 1%, increasing to 5% for patients aged 70 to 75 years and exceeding 10% in patients older than 80 years.¹ The most common disease origins of atrial fibrillation are hypertensive heart disease and ischemic heart disease.

The rate of ischemic stroke in patients with atrial fibrillation is approximately 4.5% per year but varies widely depending on the patient's age and coexistent diseases.¹ The stroke rate in patients without cardiovascular disease increases from 1.6% per year for patients in their 60s to 3% per year for patients older than 80 years.¹ Clinical risk factors that affect the stroke rate include the presence of valvular heart disease, prior thromboembolism, hypertension, diabetes, congestive heart failure (CHF), and coronary artery disease.
