    Purpose

    Recent evidence suggests early life factors correlate with atrial fibrillation (AF). We hypothesized that AF-related mortality, similar to stroke mortality, is elevated for individuals born in the southeastern US.

    Methods

    We estimated 3-year (1999-2001) average AF-related mortality rates, using US vital statistics for 55-89 year old whites (136,573 AF-related deaths) and blacks (8,288 AF-related deaths). We estimated age- and sex-adjusted odds of AF-related (contributing cause) mortality associated with birth state, and birth within the US stroke belt (SB), stratified by race. SB results were replicated using 1989-1991 data.

    Results

    Among blacks, four contiguous birth states were associated with statistically significant ORs>=1.25 compared to the national average AF-related mortality. The four highest-risk birth states for blacks also predicted elevated AF-related mortality among whites, but patterns were attenuated. The odds ratio for AF-related mortality associated with SB birth was 1.19 (CI 1.13, 1.25) for blacks and 1.09 (CI 1.07, 1.12) for whites, adjusting for SB adult residence.

    Conclusion

    Place of birth predicted AF-related mortality, after adjusting for place of adult residence. The association of AF related mortality and SB birth parallels that of other cardiovascular diseases, and may likewise indicate an importance of early life factors in the development of AF.
