He added he was surprised that the Black-white difference in heart-disease death rates owes mainly to social factors. Black Americans are 54% more likely to die of heart disease than white Americans, the study found. This is true even with a substantial overall reduction in heart disease deaths nationwide. The study used health data from more than 50,000 U.S. adults. The researchers examined links between heart-related deaths and clinical risk factors like obesity, diabetes and high blood pressure as well as lifestyle factors, including smoking, unhealthy diet, lack of exercise and too little or too much sleep.
