Doctor Cadman treated Cleo McQueen after she suffered a heart attack caused by bullimia in October 2018. Doctor Cadman told Cleo's family that the heart attack was caused by low potassium levels, and suspected that she had relapsed due to her weight loss. The next day, Cleo began having stomach pains and Doctor Cadman rushed Cleo into surgery due to suspected internal bleeding. After the operation, Doctor Cadman informed Myra McQueen and Joel Dexter that Cleo had a tear in her liver from a cracked rib sustained during CPR.
