Aug 20 (Reuters) - American ⁠Olympic bronze medallist and former ⁠1500 metres world champion Jenny Simpson has ‌been diagnosed with Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC), a rare inherited heart condition that makes a return ​to running dangerous, the ⁠athlete said on Instagram ⁠on Thursday.

The 39-year-old collapsed in June at ⁠a ‌community track event hosted by Sir Walter Running and required ⁠CPR.

"I was diagnosed with a rare inherited ​heart ‌condition, Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC)... My future ⁠is an ​incredible gift. It is hopeful and it will continue to have a great ⁠purpose. But my diagnosis also ​means it would be dangerous for me to return to running," Simpson said in ⁠a statement.

Simpson won gold in the 1,500 metres at the 2011 world championships and bronze at the 2016 Rio Olympics. ​She retired from competitive ⁠running in 2024.

She also won silver medals ​in the 1,500 metres ‌at the 2013 and ​2017 world championships.
