In 1998, the NHLBI awarded R24HL60808 for five years to provide and maintain an archive of human cardiovascular and other tissues which can be used by other United States and international investigators to study human atherosclerosis. The investigators, as part of PDAY and RFEHA, have assembled autopsy material (mostly of aorta and coronary artery, but with other tissues including liver, serum, and adipose tissue) from over 3,000 Black and white males and females. These were from autopsies on individuals ages 15 to 34 and obtained within 48 hours of death. The grant for the cardiovascular specimen and data library was renewed through July 2007.
