Happy Heart Syndrome Takotsubo syndrome may also be triggered by happy events
Overview
Takotsubo syndrome also known as Broken heart syndrome is a sudden form of heart failure perceived to be triggered by negative life events, such as experiencing fear, grief, or conflict. Researchers have found in a new study that Broken heart syndrome" may also occur after joyful life events and they call it "happy heart syndrome."
Happy heart syndrome is a rare type of takotsubo syndrome (TTS) characterized by a higher prevalence of male patients and atypical, non-apical ballooning compared with patients with negative emotional stressors.
The study has been published in the JAAC: Heart Failure.
The authors analyzed positive emotional stressors frequency, clinical characteristics, and prognostic implications in the multicenter GEIST (German-Italian-Spanish Takotsubo) Registry. The association with a preceding stressor is a characteristic feature of takotsubo syndrome (TTS). Negative emotions before Takotsubo syndrome are common and led to the popular term "broken heart syndrome." In contrast, pleasant triggers ("happy heart syndrome") are rare and are scarcely investigated. Patients enrolled in the registry were categorized according to their stressors. This analysis compared patients with pleasant emotional events with patients with negative emotional events.
Results
• Of 2,482 patients in the registry, 910 patients exhibited an emotional trigger consisting of 873 "broken hearts" and 37 "happy hearts".
• Consequently, the prevalence of pleasant emotional triggers was 1.5% of all Takotsubo syndrome cases.
• Compared with patients with Takotsubo syndrome with negative preceding events, patients with happy heart syndrome were more frequently male and had a higher prevalence of atypical ballooning patterns, particularly midventricular ballooning. In-hospital complications, including death, pulmonary edema, cardiogenic shock, or stroke, and long-term mortality rates were similar in "happy hearts" and "broken hearts."
Thus, happy heart syndrome is a rare type of Takotsubo syndrome characterized by a higher prevalence of male patients and atypical, non-apical ballooning than patients with negative emotional stressors. Despite similar short- and long-term outcomes in our study, additional data are needed to explore whether numerically lower event rates in "happy hearts" would be statistically significant in a larger sample size.
