Takotsubo cardiomyopathy has been reported after near-drowning episodes. Seizures may also trigger Takotsubo cardiomyopathy, but it is rare for Takotsubo cardiomyopathy to result in SUDEP. Recognized stressors include:
Learning of the death of a loved one
Bad financial news
Legal problems
Natural disasters
Motor vehicle collisions
Exacerbation of a chronic medical illness
Newly diagnosed, significant medical condition
Surgery
Intensive care unit (ICU) stay
Use of or withdrawal from illicit drugs
The International Takotsubo Registry reported that patients with Takotsubo cardiomyopathy, as compared with patients who had acute coronary syndrome (ACS), were more likely to be female (89.8%) and that physical triggers were more common than emotional triggers (36% vs 27.7%), although more than one quarter (28.5%) had no clear triggers. Patients with Takotsubo cardiomyopathy also had higher rates of neurologic or psychiatric disorders and a significantly lower LV ejection fraction (LVEF). The two groups had similar rates of severe inpatient complications (eg, shock, death), and independent predictors of such complications included physical triggers, acute neurologic/psychiatric diseases, elevated troponin levels, and low LVEF.
