Atrial fibrillation (AF) and co-morbidity in elderly. A population based survey of 85 years old subjects.

The occurrence of AF increases sharply with age. The aim of this study was to explore and compare prevalent co-morbidity and self-estimated health-related quality of life (HRQoL) in subjects with AF versus subjects with sinus rhythm or pacemaker in 85 years old subjects. We analyzed data from a population of 336 eighty-five years old subjects participating in the Elderly in Linköping Screening Assessment (ELSA-85) study. Medical history was obtained from postal questionnaire, medical records and during medical examination that included a physical examination, cognitive tests, non-fasting venous blood samples and electrocardiographic (ECG) examination. 19% had an ECG showing AF. There were very few significant differences regarding medical history, self-estimated quality of life (QoL), laboratory- and examination findings and use of public health care between the AF group and the non-AF group. The study showed that the population of 85 years old subjects with AF was surprisingly healthy in terms of prevalent co-existing medical conditions, healthcare contacts and overall HRQoL. We conclude that elderly patients with AF do not in general have increased co-morbidity than subjects without AF.
