The various risk stratification schemes classified variable proportions as low , moderate and high risk , but the CHA(2)DS(2)-VASc score classified the smallest proportion of patients as ' low risk ' .
Anticoagulation with vitamin K antagonists and dabigatran is cost-effective in patients at high risk of stroke , but not in patients without any other stroke risk factor beside AF .
Risk factors for thromboembolic stroke in elderly patients with chronic atrial fibrillation.
Abstract Chronic atrial fibrillation ( AF ) in the presence or absence of rheumatic valvular heart disease is associated with an increased incidence of stroke . 1,2 We reported in a prospect i ve study that at 27-month follow-up , echocardiographic left ventricular ( LV ) hypertrophy in elderly patients with systolic or diastolic hypertension was associated with an increased incidence of new atherothrombotic brain infa rct ion . 3 We also demonstrated in a prospect i ve study that at 3-year follow-up , risk factors for atherothrombotic brain infa rct ion were cigarette smoking , systolic or diastolic hypertension and diabetes mellitus in elderly men and systolic or diastolic hypertension , diabetes mellitus and obesity in elderly women . 4 This report correlates in elderly patients with chronic AF the prevalence of thromboembolic ( TE ) stroke with the presence or absence of rheumatic mitral stenosis , mitral anular calcium , valvular aortic stenosis , systolic or diastolic hypertension , prior myocardial infa rct ion , left atrial enlargement and LV hypertrophy
