Psychosocial Stress and Takotsubo Syndrome: A Systematic Review of Precipitants and Recurrence

Abstract

Introduction: Takotsubo syndrome (TTS), also known as broken heart syndrome, is typically triggered by acute emotional or physical stress. However, the spectrum of psychosocial precipitants and recurrence rates are not fully characterized.
Methods: A systematic literature search in PsycINFO, PubMed, and EMBASE (2000–2023) for observational studies of TTS with systematic recording of triggers. Exclusion: purely physical triggers (e.g., surgery, sepsis). Data extracted on trigger types, psychiatric comorbidities, and recurrence.
Results: 42 studies (n=7,800 TTS patients) included. Emotional triggers were identified in 56% (range 40–70%), most commonly: death of a loved one (32%), relationship conflict (18%), financial stress (12%), and public speaking (4%). Unexpectedly, positive emotional events (“happy heart” syndrome) were reported in 4%. Psychiatric comorbidities (anxiety, depression, or personality disorders) were present in 39% of patients. Recurrence rate at 5 years: 5.2% (95%CI 3.8–6.8%). Predictors of recurrence: persistent psychiatric illness (OR 2.9) and lack of beta-blockers (OR 1.8).
Discussion: The predominance of negative emotional triggers supports the catecholamine surge hypothesis. The small proportion of positive triggers suggests that high adrenergic tone per se, rather than valence, is key. Limitations include recall bias and underreporting of milder triggers.
Conclusions: Psychosocial stressors are the most common triggers of TTS, with a 5% recurrence risk over 5 years. Screening for psychiatric illness and stress management should be integrated into TTS care pathways.
