Tuscon, Arizona -
(KVOA) A Tucson, Arizona woman so distraught over the loss of her dog had to be hospitalized.
It happened last week when three chihuahuas on leashes were attacked by a pit bull.
One of the chihuahuas, named Bella was killed.
Hours after the attack Bella's owner suffered stress-induced cardiomyopathy, also known as Broken Heart Syndrome.
According to the American Heart Association it can strike even when you're healthy.
Broken Heart Syndrome can be misdiagnosed as a heart attack but there's no evidence of blocked heart arteries.
