Overview
The clinical presentation, laboratory findings and imaging studies of stress cardiomyopathy resembles that of anterior MI and must be differentiated from it. Also, stress cardiomyopathy must be differentiated from Takotsubo-like cardiomyopathy, such as that due to pheochromocytoma.
Differentiating Stress Cardiomyopathy from other Diseases
The presentation of stress cardiomyopathy mimics that of anterior wall MI and must be differentiated from it:[1]
| Stress Cardiomyopathy | Anterior Wall MI | |
|---|---|---|
| Chest pain and dyspnea as presenting symptoms | ✔ | ✔ |
| ST elevation in precordial leads | ✔ | ✔ |
| Peak CK-MB value | <50 U/L | ↑↑↑ |
| 6-month outcome | Favorable outcome | Higher rates of:
|
Stress cardiomyopathy must also be differentiated from Takotsubo-like syndrome caused by medical conditions, such as pheochromocytoma:[2]
| Stress Cardiomyopathy | Takotsobu-like Syndrome | |
|---|---|---|
| Chest pain mimicking MI | ✔ | ✔ |
| EKG findings (ST elevation) | ✔ | ✔ |
| Positive cardiac enzymes | ✔ | ✔ |
| LV regional dysfunction | ✔ | ✔ |
| Patient profile | Post-menopausal women | Younger patients with less female predominance |
| Catecholamine levels | Transient elevation | Constantly elevated |
| Complications | Higher rate of complications, including: |
