What causes broken heart syndrome?

The exact cause of broken heart syndrome is not fully understood. When you react to a physical or emotional stress, your body releases stress hormones in your blood like adrenalin, noradrenalin, epinephrine and norepinephrine. Experts think that these hormones temporarily interfere with your heart’s function.

Broken heart syndrome:

• Disrupts your heart’s normal, steady rhythm (pattern of heartbeats).
• Causes part of your heart to temporarily enlarge (the lower part of your left ventricle).
• Leads to even more forceful contractions in other areas of your heart.

These changes cause temporary heart muscle failure.
