Takotsubo syndrome: Understanding broken heart syndrome

Takotsubo syndrome, commonly referred to as ‘broken heart syndrome’, is a medical condition characterized by temporary weakening of the myocardium. The clinical presentation often mimics that of an acute myocardial infarction (heart attack).

The condition is frequently triggered by intense emotional or physical stressors, such as the death of a loved one, severe separation, sudden shock, intense fear, or significant physical strain like surgery or severe illness. While it can affect anyone, it appears more frequently in postmenopausal women.

Although the exact mechanism is not fully understood, a leading theory suggests that a sudden surge of stress hormones, particularly adrenaline, causes transient dysfunction in the blood vessels and heart muscle. During an episode, a portion of the left ventricle may become akinetic and enlarged, resembling the shape of a ‘takotsubo’—a traditional Japanese octopus trap with a narrow opening and a round base.
