Broken heart syndrome is a temporary heart condition that's often brought on by stressful situations and extreme emotions. The condition can also be triggered by a serious physical illness or surgery.

People with broken heart syndrome may have sudden chest pain or think they're having a heart attack. Broken heart syndrome affects just part of the heart, temporarily disrupting the heart's usual pumping function. The rest of the heart continues to work properly or may even squeeze (contract) more forcefully.

The symptoms of broken heart syndrome are treatable. Broken heart syndrome usually reverses itself in days or weeks.

Broken heart syndrome may also be called:

  • Stress cardiomyopathy
  • Takotsubo cardiomyopathy
  • Apical ballooning syndrome


Broken heart syndrome signs and symptoms can mimic a heart attack and may 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 or emergency services if you have 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.


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 squeezing (constriction) of the large or small arteries of the heart may play a role. People who have broken heart syndrome may also have a change in the structure of the heart muscle.

Broken heart syndrome is often preceded by an intense physical or emotional event. For example, an acute illness (such as an asthma attack or COVID-19 infection), major surgery or a broken bone can lead to broken heart syndrome. Anything that causes a strong emotional response, such as a death or other loss, or a strong argument may trigger this condition.

Rarely, use of certain drugs may lead to broken heart syndrome, including:

  • Emergency medications used to treat severe allergic reactions or severe asthma attacks
  • Some medications used to treat anxiety
  • Nasal decongestants
  • Illegal stimulant drugs, such as methamphetamine and cocaine

Always tell your health care provider about the medications you take, including those bought without a prescription. When starting a new medication, talk to your provider about the potential risks and side effects.

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. In broken heart syndrome, the heart arteries are not blocked, although blood flow in the arteries of the heart may be reduced.

Risk factors

Known risk factors for broken heart syndrome include:

  • Sex. Broken heart syndrome is more common in women than in men.
  • Age. It appears that most people who have broken heart syndrome are older than 50.
  • A previous or current mental health disorder. People who have anxiety or depression may have a higher risk of broken heart syndrome.


Rarely, broken heart syndrome can cause death. However, most people who have broken heart syndrome quickly recover and don't have long-lasting effects.

Other possible complications of broken heart syndrome include:

  • Backup of fluid into the lungs (pulmonary edema)
  • Low blood pressure (hypotension)
  • Irregular heartbeats (arrhythmias)
  • Heart failure
  • Blood clots forming within the heart due to the weakened heart muscle

Broken heart syndrome may occur again after another stressful event. However, the odds of this happening are low.


To prevent another episode of broken heart syndrome, many health care providers recommend long-term treatment with beta blockers or similar medications that block the potentially damaging effects of stress hormones on the heart.

Some people who have chronic stress may have an increased risk for broken heart syndrome. Taking steps to manage emotional stress can improve heart health and may help prevent broken heart syndrome.
