Key result
Treadmill exercise stress testing triggers mid-ventricular variant takotsubo cardiomyopathy.
Why the study?
Takotsubo cardiomyopathy typically presents with apical systolic dysfunction after stress, but variant patterns and triggers are less well characterized.
Case Report (n=1)
Treadmill exercise stress testing can act as a physical stressor triggering a mid-left ventricular ballooning variant of takotsubo cardiomyopathy.
Treadmill testing may trigger mid-ventricular takotsubo cardiomyopathy; this Level 5 case leaves open its incidence and any protocol implications.
Stress-induced cardiomyopathy, also known as takotsubo cardiomyopathy, presents similar to a myocardial infarction after a physical or emotional stressor but without any evidence of obstructive coronary artery disease. Different patterns of myocardial involvement and several triggering events have been reported, but classically this condition is characterized by a stress-induced transient left ventricular apical systolic dysfunction. We describe a case of treadmill exercise stress testing-triggered variant of takotsubo cardiomyopathy with mid-left ventricular hypokinesis.

Cantor et al. (2018) conducted a case report in Takotsubo cardiomyopathy (n=1). Treadmill exercise stress testing was evaluated on Development of mid-left ventricular hypokinesis. Treadmill exercise stress testing triggered a variant of takotsubo cardiomyopathy characterized by mid-left ventricular hypokinesis.
