The objective of the study was to determine whether chronic osteomyelitis (COM) is associated with increased risk of new-onset atrial fibrillation (AF).MethodsA national insurance claim data set of 23 million enrollees was used to identify 19,002 patients with newly-diagnosed COM and 76,008 randomly selected age- and sex-matched control subjects between January 1, 2000 and December 31, 2009 for comparing the risk and incidence of AF. The study end point was defined as the first diagnosis of AF, death, withdrawal from the insurance program, or the end of 2010.ResultsDuring a follow-up period of 91,927 person-years, the incidence of new-onset AF in COM cohort was 1.42-fold higher than for the non-COM cohort (4.54 vs 3.19 per 1000 person-years). After adjusting for age, sex, and classical AF risk factors such as hypertension, diabetes, heart failure, coronary artery disease, and valvular heart disease, the risk of new-onset AF remained significantly higher in the COM cohort (hazard ratio [HR], 1.33; 95% confidence interval [CI], 1.18-1.49; P < 0.0001). In age-stratified analysis, the younger population carried a higher risk for incident AF than the elderly population (from HR 2.05; 95% CI, 1.12-3.74 in age younger than 50 years to HR 1.19; 95% CI, 0.95-1.49 in age 80 years and older). The adjusted Kaplan-Meier analysis showed a lower AF-free survival rate in the COM group compared with the control group (log-rank P < 0.0001) during the follow-up period.ConclusionsThis study showed that patients with COM carry an increased risk for developing new-onset AF, particularly in the younger population. Further studies are required to explore the underlying mechanisms that link COM and AF.
