Elevated heart rate might show which Black patients are at risk for atrial fibrillation Every 10-beat-per-minute increase in resting heart rate is linked to a 9% higher risk of A-fib A-fib greatly increases risk of stroke and heart disease TUESDAY, Nov. 5, 2024 (HealthDay News) -- An elevated heart rate could provide an important clue to which Black adults often have a dangerous heart rhythm disorder, a new study finds. Higher resting heart rate is associated with increased risk of , researchers found.
What’s more, the higher a person’s heart rate, the higher their risk for A-fib, results showed. Every 10-beats-per-minute increase in heart rate is associated with a 9% higher risk of developing afib, researchers reported recently in the journal . This study is the first to look specifically at A-fib risk among Black patients, said lead researcher , a cardiologist with the University of Washington School of Medicine in Seattle.
“This study is useful because, among Black adults, we know little about risk factors for cardiovascular disease -- and specifically for A-fib, which can lead to heart failure, stroke, dementia and death,” Yogeswaran said in a university news release. “Paradoxically, Black adults have a lower reported clinical prevalence of atrial fibrillation than white adults, but have a much higher risk of A-Fib-associated consequences such as stroke and death,” Yogeswaran added. With A-fib, the upper chambers of the heart, called the atria, start to beat i.
