Key result
The apical variant of Takotsubo cardiomyopathy was associated with significantly lower left ventricular ejection fraction (36% vs 42.4%, P<0.01) compared to the non-apical variant.
Why the study?
Do patients with the apical variant of Takotsubo cardiomyopathy differ from those with the non-apical variant in clinical presentation and outcomes?
Population
114 patients diagnosed with Takotsubo cardiomyopathy between 2003 and 2015 from an institutional database.
Comparison
Apical form of Takotsubo cardiomyopathy vs Non-apical form of Takotsubo cardiomyopathy

Apical Takotsubo may warrant closer monitoring for systolic dysfunction; leaves open variant-specific outcome differences.

Absolute Event Rate: 36% vs 42.4%
p-value: p=<0.01
The apical and non-apical variants of Takotsubo cardiomyopathy differ significantly in clinical presentation, with the apical form associated with older age, lower ejection fraction, and a higher tendency for complications like cardiogenic shock.
El‐Battrawy et al. (2016) conducted a cohort in Takotsubo cardiomyopathy (n=114). Apical variant of Takotsubo cardiomyopathy vs. Non-apical variant of Takotsubo cardiomyopathy was evaluated on Left ventricular ejection fraction (EF) (p=<0.01). The apical variant of Takotsubo cardiomyopathy was associated with significantly lower left ventricular ejection fraction (36% vs 42.4%, P<0.01) compared to the non-apical variant.
