Project
The International Primate Heart Project (IPHP) is a collaboration between veterinary practitioners, cardiac physiologists and cardiologists setup to better understand cardiac disease in great apes. Cardiac disease has been identified as a leading cause of death in captive great ape populations; however, the underlying cause is presently not known. Furthermore, the knowledge base regarding normal cardiac structure and function in our nearest evolutionary cousins is extremely limited. Accordingly, the IPHP aims to set recognized reference values for cardiac structure and function in all of the great apes in order to be better able to diagnose disease, and to investigate the specific causes of cardiac disease in great apes.
