Broken heart syndrome

DEFINITION

Broken heart syndrome is a temporary heart condition that’s often brought on by stressful situations, such as the death of a loved one. People with broken heart syndrome may have sudden chest pain or think they’re having a heart attack. In broken heart syndrome, there’s a temporary disruption of your heart’s normal pumping function, while the remainder of the heart functions normally or with even more forceful contractions.

 

Broken heart syndrome may be caused by the heart’s reaction to a surge of stress hormones. The condition may also be called takotsubo cardiomyopathy, apical ballooning syndrome or stress cardiomyopathy by doctors.

The symptoms of broken heart syndrome are treatable, and the condition usually reverses itself in about a week.

CAUSES

The exact cause of broken heart syndrome is unclear. It’s thought that a surge of stress hormones, such as adrenaline, might temporarily damage the hearts of some people. How these hormones might hurt the heart or whether something else is responsible isn’t completely clear. A temporary constriction of the large or small arteries of the heart may play a role.

 

Broken heart syndrome is often preceded by an intense physical or emotional event. Some potential triggers of broken heart syndrome are:

  • News of an unexpected death of a loved one
  • A frightening medical diagnosis
  • Domestic abuse
  • Losing a lot of money
  • Natural disasters
  • A surprise party
  • Having to perform publicly
  • Job loss
  • Divorce
  • Physical stressors, such as an asthma attack, a car accident or major surgery

It’s also possible that some drugs, rarely, may cause broken heart syndrome by causing a surge of stress hormones. Drugs that may contribute to broken heart syndrome include:

  • Epinephrine (EpiPen, EpiPen Jr), which is used to treat severe allergic reactions or a severe asthma attack
  • Duloxetine (Cymbalta), a medication given to treat nerve problems in people with diabetes, or as a treatment for depression
  • Venlafaxine (Effexor XR), which is a treatment for depression
  • Levothyroxine (Synthroid, Levoxyl), a drug given to people whose thyroid glands don’t work properly

How is broken heart syndrome different from a heart attack?

Heart attacks are generally caused by a complete or near complete blockage of a heart artery. This blockage is due to a blood clot forming at the site of narrowing from fatty buildup (atherosclerosis) in the wall of the artery. In broken heart syndrome, the heart arteries are not blocked, although blood flow in the arteries of the heart may be reduced.

SYMPTOMS

Broken heart syndrome symptoms can mimic a heart attack. Common symptoms include:

  • Chest pain
  • Shortness of breath
  • Any long-lasting or persistent chest pain could be a sign of a heart attack, so it’s important to take it seriously and call 911 if you experience chest pain.

When to see a doctor

If you’re having any chest pain, a very rapid or irregular heartbeat, or shortness of breath after a stressful event, call 911 or emergency medical assistance immediately.
