Our aim was to study the clinical profile of octogenarians treated with oral anticoagulation and to study the effect of age on the quality of VKAs anticoagulation. Data are from a prospective national registry in an adult Spanish population of nonvalvular AF. We included 1637 patients who had been receiving VKAs for at least 6months before enrolment. Mean age was 73.8±9.4years. Patients aged >80years (N=429) had a high risk profile with higher risk of stroke and bleeding than younger patients; CHA2DS2-VASc (Cardiac failure, Hypertension, Age>74, Diabetes, Stroke, Vascular disease, Age 65-74years, and Sex category) 4.5±1.3 vs. 3.5±1.6, p80years (N=429) had a high risk profile with higher risk of stroke and bleeding than younger patients; CHA2DS2-VASc (Cardiac failure, Hypertension, Age>74, Diabetes, Stroke, Vascular disease, Age 65-74years, and Sex category) 4.5±1.3 vs. 3.5±1.6, p74, Diabetes, Stroke, Vascular disease, Age 65-74years, and Sex category) 4.5±1.3 vs. 3.5±1.6, p64years), Drugs/alcohol concomitantly) 2.4±0.9 vs. 1.9±1.1, p In this large registry octogenarians with nonvalvular AF had high risk of stroke and bleeding and frequent renal disease. VKAs anticoagulation quality was similar in octogenarians and in younger patients.
