Broken-heart syndrome is a real medical condition.

One morning, Joanie Simpson woke with a terrible backache. Her chest started hurting when she turned over.

Within 20 minutes, she was at a local emergency room. Soon she was being airlifted to a hospital in Houston, where physicians were preparing to receive a patient exhibiting the classic signs of a heart attack.

But tests at Memorial Hermann Heart & Vascular Institute-Texas Medical Center revealed something very different. Doctors instead diagnosed Simpson with Takotsubo cardiomyopathy, a condition with symptoms that mimic heart attacks. It usually occurs following an emotional event such as the loss of a spouse or child.

That link has given the illness its more colloquial name: broken-heart syndrome.

Her dog

In Simpson’s case, the event that she says tipped her over the edge was the recent death of her beloved Yorkshire terrier, Meha.

“I was close to inconsolable,” she said. “I really took it really, really hard.”

9-year-old Meha was suffering from congestive heart failure.

The dog was like a daughter, Simpson said. She lived with Simpson two hours northwest of San Antonio, Tex, in the town of Camp Woods. She adored jumping into the swimming pool, and when Simpson and her husband grilled on Friday nights, Meha was given her own hamburger.

“The kids were grown and out of the house, so she was our little girl,” said Simpson, a 62-year-old retiree who previously worked in medical transcription.

And then, one day, Meha passed on.

Grieving pets

Simpson’s 2016 experience is described this week in the New England Journal of Medicine — not because of the dog’s role, according to one of her doctors, Abhishek Maiti, but because hers was a “very concise, elegant case” of a fascinating condition that research has established as quite real and sometimes fatal.

Although not the first published case linking broken-heart syndrome to stress over a pet’s death, it underscores something many animal owners take as a given: that grieving for sick or deceased pets can be as gutting as grieving for humans.

A growing body of research supports this notion, which was echoed in a recent study that found pet owners with chronically ill animals have higher levels of “caregiver burden,” stress and anxiety. It’s the flip side of evidence that links pets to health and happiness, which gets more attention. Not that people who have lost beloved animals are likely to be surprised.

A new pet

Once medications stabilized Simpson, the physicians talked to her about the stress in her life, and they told her about broken-heart syndrome. It “made complete sense,” Simpson said. She was sent home after two days, and though she still takes two heart medications, she is doing fine.

She even has a cat named Buster now.
