Overview
Stress cardiomyopathy is a cardiac syndrome characterized by a reversible transient apical ventricular dysfunction.
Diagnosis
Mayo Criteria
Mayo Clinic Criteria for Apical Ballooning Syndrome. All 4 must be present [1]:
- Transient hypokinesis, akinesis or dyskinesis of the left ventricular mid-segments with or without apical involvement. The regional wall motion abnormalities extend beyond a single epicardial vascular distribution. A stressful trigger is often, but not always present
- Absence of obstructive coronary disease or angiographic evidence of acute plaque rupture.
- New electrocardiographic abnormalities (either ST-segment elevation and/or T- wave inversion) or modest elevation in cardiac troponin.
- Absence of pheochromocytoma and myocarditis
