Grandmother Joanie Simpson, 62, loves her pets and was especially close to her Yorkie, named Meja. She is now at the center of a medical mystery. Joanie was home alone when Meja died of congestive heart failure at 8 years old. Joanie was griefstricken. Four days later, Joanie was airlifted to Houston's Memorial Hermann Medical Center experiencing all the symptoms of a massive heart attack. Joanie was diagnosed with Takotsubo cardiomyopathy, or broken heart syndrome. #InsideEdition
