Mid-Left Ventricular Ballooning Variant Takotsubo Syndrome Induced by Treadmill Exercise Stress Testing

Abstract EN

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.
