Donna Harris was the doctor who attended to Lloyd Mullaney when he was rushed into Weatherfield General with chest pains after a 5k run on the Red Rec in May 2014.

She conducted tests on Lloyd upon his arrival by ambulance and told daughter Jenna Kamara that they were awaiting results but that the swift arrival of the paramedics at the scene had improved his chances. He was kept in overnight but suffered a severe angina attack the next day. Donna had him rushed down to theatre where a stent was fitted to help him in his recovery.
