moking prevalence has decreased in black and white adults of all ages, and now is about equal in both groups. Overall, smoking by blacks declined from 34 percent to 26 percent, and by whites from 29 percent to 26 percent. Smoking prevalence was higher in black men than white men (33 percent versus 28 percent), but lower in black women than white women (21 percent versus 24 percent). The unwelcome news is that obesity in both races has increased significantly from 29 percent to 40 percent overall for blacks, and from 21 percent to 29 percent for whites.

8:45 a.m. Abstract 3690 African-Americans have higher death risk after reperfusion. Studies have shown a higher death rate for African-Americans with coronary artery disease compared to Caucasians.

Researchers evaluated data from 32,419 patients treated to restore blood flow to a block artery (reperfusion therapy) due to STEMI. Coronary angiography rates were similar but African-Americans were less likely to undergo a surgical procedure to restore blood flow. While death rates within 30 days for the two groups were similar, in-hospital stroke and bleeding, and one-year mortality were "significantly higher" among African-Americans. Detailed study of this disparity is needed, the scientists say.
