Takotsubo syndrome is an intriguing phenomenon of a transient, reversible heart failure syndrome. The classically described apical type has been extensively published, however the detailed characteristics of the non-apical variant type remains to be determined.
We retrospectively reviewed 75 cases of Takotsubo syndrome diagnosed between October 2004 and August 2016. The baseline characteristics were analyzed and compared between the apical and the non-apical types.
In our whole cohort, the baseline characteristics for gender and age were 93% female with median age of 69. Apical type was predominant (77%) and the comparison of the baseline characteristics are shown in Table 1. Gender and age were comparable, however apical type had higher history of hypertension while lower history of diabetes, hyperlipidemia, or smoking. Non-apical type had lower ejection fraction (mean 38.4% versus apical type 41.8%) and statistically significant higher incidence of ejection fraction below 40%.
Apical and non-apical Takotsubo syndrome had similar baseline characteristics however the incidence of low ejection fraction was higher in non-apical type.
