Overview
Stress cardiomyopathy can be divided into several types, depending on the location of regional wall motion abnormality. The area of motion abnormality (whether hypokinesia, dyskinesia or akinesia) can be detected on echocardiography or left ventriculography. The most common type is the apical type, resulting in apical ballooning. Apical ballooning is the most common type of the stress cardiomyopathy. In a minority of patients reverse takotsubo have been described in which unlike apical ballooning the basal and mid ventricular segments of the left ventricle are akinetic.
Classification
Stress cardiomyopathy can affect different segments of the heart. The region of wall motion abnormality can be detected on echocardiography or left ventriculography. The most common type of stress cardiomyopathy is the apical type, which results in hypokinesia of the apical and mid-ventricular segments. Stress cardiomyopathy can be divided according to location of wall motion abnormality into:[1][2][3][4]
| Type of Stress Cardiomyopathy | Location of Wall Motion Abnormality | Incidence (%) | Properties |
|---|---|---|---|
| Typical Type(s) | Apical Type | 81.7 |
|
| Atypical Type(s) | Mid-ventricular Type | 14.6 |
|
| Basal Type | 2.2 |
| |
| Focal Type | 1.5 |
| |
| Global Type | Very rare |
