Health Issues Before Makena White’s Death

According to social media posts reviewed after her passing, Makena White had previously shared her struggles with heart-related health issues. In May, she revealed she was dealing with a heart defect and was using monitoring equipment. She even joked about wearing a Holter monitor while attending a cardiac surgery conference for work.
