A strong link has been found between the risk of atrial fibrillation and race. Whites with heart failure are at a much greater risk for atrial fibrillation, compared to blacks and Hispanics. Heart failure is a common risk factor for atrial fibrillation and affects nearly 5.8 million Americans.
The researchers reviewed data from over 68,000 Americans with heart failure aged 45 to 95. The group contained a mix of Hispanics, whites, and blacks.
The risk of atrial fibrillation was 23 percent lower in blacks compared to whites, and Hispanics had a 27 percent lower risk compared to whites.
Study researcher Dr. Eric Shulman explained, “[the results are] especially interesting because, despite having many risk factors for [atrial fibrillation], Hispanic and African American patients had a lower risk of developing [atrial fibrillation].”
The study was presented at the at the Heart Rhythm Society’s annual meeting in San Francisco and still needs to be peer-reviewed.
