A higher urinary albumin-to-creatinine ratio (ACR), an important marker of kidney injury, was linked with a greater risk of incident coronary heart disease (CHD) but not recurrent CHD in blacks compared with whites, suggesting that blacks appear more susceptible to vascular injury, according to a report in the Journal of the American Medical Association (2013;310:706-714). 

Over 4.4 years in individuals free of CHD at baseline, age- and sex-adjusted incidence rates of CHD per 1,000 person-years of follow-up rose with increasing ACR, with rates nearly 1.5-fold greater in the highest ACR category (greater than 300 mg/g) in blacks than whites.
