Purpose: Heart Failure is common in the western world, has multiple causes and confers significant morbidity and mortality. It is thought a significant proportion of Heart Failure patients also have Atrial Fibrillation although figures from a large population in the UK are lacking. We studied the prevalence of Atrial Fibrillation in patients with Heart Failure in the North West of England. Methods: Anonymous data of adult patients aged ≥ 18 with Heart Failure and Table 1. Prevalence of atrial fibrillation in patients with heart failure according to age groups Heart failure patients (%) Atrial fibrillation % Mean age (years) All age groups 31760 (100.0) 34.6 73.6 Age group 18–29 years 256 (0.8) 8.6 24.2 Age group 30–39 years 528 (1.7) 8.1 35.4 Age group 40–49 years 1158 (3.6) 12.8 45.2 Age group 50–59 years 2571 (8.1) 21.5 55.2 Age group 60–69 years 5423 (17.1) 29.0 65.0 Age group 70–79 years 9743 (30.7) 36.8 74.8 Age group 80–89 years 9503 (29.9) 42.4 84.0 Age group 90–99 years 2533 (8.0) 40.5 92.6 Age group ≥ 100 years 45 (0.1) 42.2 101.8 Atrial Fibrillation attending 7 hospitals between 2000 and 2013 was obtained and processed using the ACALM (Algorithm for Co-morbidity, Associations, Length of stay and Mortality) study protocol. ACALM uses the ICD-10 and OPCS-4 coding systems to identify patients. Analyses was performed in SPSS. Results: Of 929465 adult patient population there were 31760 (3.4%) patients with Heart Failure. Mean age 73.6 years, Male 50.3%. Of these 10992 patients had Atrial Fibrillation (34.6%). The prevalence of Atrial Fibrillation in patients with Heart failure increases with age from 8.1% in the 30-39 year age group to 42.4% in the 80-89 years group. Conclusion: Whilst a significant number of elderly patients with Heart Failure patients do have concurrent Atrial Fibrillation, the majority of patients do not. Our findings are important to appreciate whilst optimising Heart Failure management in elderly patients.
