African Americans who smoke seem at higher risk of coronary heart disease

African Americans who smoke appear to have more than twice this risk of  developing coronary heart disease compared to those who do not smoke, a new study has found. The findings — the first up-close look at the relationship between smoking and coronary heart disease in this population—also examined the risk for plaque buildup in the arteries of African Americans who smoke. Excessive plaque in the arteries is a known predictor of heart attacks and heart failure.

Chan School of Public Health.
