Takotsubo Syndrome or Peripartum Cardiomyopathy? Depends on Who You Are Talking to

Abstract

Takotsubo syndrome (otherwise known as broken-heart syndrome or left ventricular apical ballooning) is a rare cause of reversible heart failure that predominantly affects postmenopausal women. It was first described by Japanese researchers in the 1990s and has become established as a differential for heart failure following a physically or psychologically stressful event. This was popularised by a spike in cases following natural disasters in Japan. As the recognition of takotsubo syndrome in the differential diagnosis for sudden, onset heart failure in a previously healthy individual has grown, so has the discussion concerning takotsubo in the peripartum period. Peripartum cardiomyopathy is a rare cause of reversible heart failure in the latter weeks of pregnancy and the postpartum period. Morbidity and mortality for both cardiomyopathies can be highly variable, ranging from complete recovery of cardiac function to life threatening arrhythmias and even death. This rapid review highlights the similarities between both cardiomyopathies and challenges the hitherto assumption that both takotsubo and peripartum cardiomyopathies are distinct entities that can easily be distinguished from one another. The implications of this are significant within the context of the behavioural aspects of diagnosis, treatment, and outcome.
