SDPB's Charles Michael Ray speaks with Dr. James Walder about a new study looking at medications that aim to reduce heart attacks in Native American patients. The set of drugs act as platelet inhibitors to reduce the chance of blood clots that can cause heart attacks. The drugs may have different effects based on genetic background. Dr. Walder is the Principal Investigator for this research study and a cardiologist with the Heart Doctors in Rapid City and the Medical Director of the Black Hills Cardiovascular Research Group.
