A serious heart condition known as atrial fibrillation – irregular heart rhythm – has been found to have deadlier consequences in blacks than in whites. Atrial fibrillation affects roughly one percent of Americans and over five percent of those over the age of 65. Atrial fibrillation has been linked to a higher risk of stroke and other heart complications.
The study included over 15,000 blacks and whites who were followed on average for 21 years. During the follow-up period, nearly 2,350 cases of atrial fibrillation emerged, and blacks were found to have double the risk of stroke, heart disease, heart failure, and all-cause mortality, compared to whites had atrial fibrillation.
Lead author Dr. Jared Magnani said, “We knew blacks were likely to have an increased risk of stroke, but the findings for heart failure, [heart disease] and mortality are novel and important. There needs to be further investigation. It’s going to be important to dissect the mechanisms behind why blacks with atrial fibrillation are highly more likely to have adverse outcomes than whites.”
