Researchers are to look into why great apes are susceptible to heart disease while in the care of humans.
A study of primates at European zoos found the condition was a “major cause” in the death of primates like gorillas and chimps.
Unlike humans, experts do not believe the disease in great apes is linked to poor diet and lifestyle.
It is also hoped the Twycross Zoo project will uncover the specific type of heart disease affecting the animals.
The Ape Heart Project is being carried out in conjunction with experts at the University of Nottingham.
Their work comes after a mortality review of European zoos, between 2003-14, uncovered how the apes had suffered from the condition.
Dr Victoria Strong, from the university’s School of Veterinary Medicine and Sciences, said: “At the moment we’re unsure why great apes in human care develop heart disease.
“We have also yet to find out whether their wild counterparts are affected to the same degree.
The project has also produced some initial guidelines aimed at improving the health of apes at European zoos.
It has suggested all primates, which go in for surgery under anaesthetic, have their blood pressure assessed and a heart ultrasound carried out.
It is hoped it will enable zoos to identify animals with heart disease problems before it is too late for treatment.
