Takotsubo syndrome, or previously named as Takotsubo cardiomyopathy, is an increasingly recognized acute reversible form of heart failure, which is typically seen in postmenopausal women following emotional or physical stress. Although several mechanisms regarding pathophysiology had been proposed, the most common ones include catecholamine toxicity, diffuse epicardial coronary artery spasm and microvascular dysfunction. A vast majority of patients with TTS (>90%) have good prognosis as they regain normal left ventricular systolic function in 3-6 months after the acute phase. Increased awareness among physicians led to the recognition of a great number and variety of conditions associated with TTS and played a key role for the development of new diagnostic criteria. However, there are still big gaps in the management and treatment of this syndrome to be supported with further well-designed randomized controlled trials.
