Cardiovascular disease is common in great apes (gorillas, chimpanzees, orangutans, and humans).  As in humans, physical factors like age, sex, and family history are factors in the development of heart disease.  Recently, the Louisville Zoo managed an older male orangutan with advanced stage heart disease and heart failure.  Although “Teak” died in 2024 from heart disease, he was able to live a longer and healthier life despite his condition due to medical intervention and close monitoring by veterinarians.

Teak’s medical management was directed by Zoo veterinarians and consulting with a cardiologist (heart specialist). His treatment included taking medication at least twice daily.  Zookeepers are usually able to medicate animals by giving medication in favorite food items, like oatmeal or yogurt. Teak was a very willing participant in his health monitoring.  Working through a safe barrier, Teak would present his arms and chest for veterinarians and veterinary technicians to draw blood and conduct heart ultrasound exams.
