Association of kidney stones with atherosclerotic cardiovascular disease among adults in the United States: Considerations by race-ethnicity.

Background: There is a paucity of research examining the relationship between kidney stones and risk of cardiovascular disease while considering individuals of different race-ethnicities.

Purpose: The purpose of this study was to examine the association between history of kidney stones and increased odds of atherosclerotic cardiovascular disease (via the Pooled Cohort Equations) across race-ethnicity groups.

Methods: 5571 participants aged 40-79 from the 2007-2012 cycles of the NHANES were used for this study. A history of kidney stones was collected from survey data. Predicted odds of having a 10-year atherosclerotic cardiovascular disease (ASCVD) event was assessed from the Pooled Cohort Equations.

Results: After adjustments, having kidney stones was not associated with an increase odds of having an ASCVD event within the next 10-years (OR 1.03; 95% CI: 0.58-1.82, P=0.91). However, among non-Hispanic blacks, those with kidney stones had a 2.24 increased odds (OR 2.24; 95% CI: 1.08-4.66; P=0.03) of having an ASCVD event within the next 10-years when compared to non-Hispanic blacks with no history of a kidney stone.

Conclusion: Kidney stones were associated with 10-year risk of a future ASCVD event among non-Hispanic blacks.
