BACKGROUND-Genomewide association studies have identified multiple genetic variants associated with breast cancer. The extent to which these variants add to existing risk-assessment models is unknown.

We sought to evaluate long-term PCI outcomes for racial and ethnic minorities in the modern era, as well as DES use, safety, and effectiveness, using a large nationally representative patient sample. We examined data from the National Cardiovascular Data Registry CathPCI Registry linked to Medicare claims data to identify any differences in patterns of DES and BMS use among racial and ethnic groups, to describe and compare outcomes after PCI for each racial and ethnic group, and to assess comparative long-term outcomes after DES versus BMS use within each racial and ethnic group.
