Key result
Inverted takotsubo cardiomyopathy was associated with more triggering stress but lower rates of cardiogenic shock (10% vs 36%, P=0.023) compared to mid or apical variants.
Why the study?
Are the clinical features, laboratory parameters, and imaging findings of inverted takotsubo cardiomyopathy different from those of mid or apical variants?
Population
103 patients enrolled from a takotsubo cardiomyopathy (TTC) registry database
Comparison
Inverted (reverse) takotsubo cardiomyopathy (n=20) vs Mid or apical variant takotsubo cardiomyopathy
Design
Cohort
Follow-up

May identify lower-shock-risk takotsubo subset; leaves open need for variant-specific prospective validation.
Observational (n=103)
Are the clinical features, laboratory parameters, and imaging findings of inverted takotsubo cardiomyopathy different from those of mid or apical variants?
Absolute Event Rate: 10% vs 36%
p-value: p=0.023
Inverted takotsubo cardiomyopathy presents in younger patients with more frequent triggering stress and higher myocardial injury markers, but less severe heart failure symptoms and lower NT-proBNP compared to typical variants.
Song et al. (2011) conducted an observational in Takotsubo cardiomyopathy (n=103). Inverted takotsubo cardiomyopathy vs. Mid or apical variant takotsubo cardiomyopathy was evaluated on Cardiogenic shock (p=0.023). Inverted takotsubo cardiomyopathy was associated with more triggering stress but lower rates of cardiogenic shock (10% vs 36%, P=0.023) compared to mid or apical variants.
