Overview
In patients with stress cardiomyopathy, coronary angiography usually shows normal anatomy of the coronary arteries and no evidence of coronary artery stenosis.
Other Imaging Findings
Positron Emission Tomography (PET) Scan
In patients with stress cardiomyopathy, a PET scan may be done. Areas of hypokinesia or dyskinesia have reduced glucose utilization compared to normal regions.[1]
Coronary Angiography
- Stress cardiomyopathy can mimic an acute MI, mainly anterior MI, since the clinical presentation, ECG and laboratory findings are similar. Hence, coronary angiography is considered a great diagnostic modality to differentiate between the two diagnoses.
- A normal angiography or absence of substantial coronary stenosis supports the diagnosis of stress cardiomyopathy.[2][3][4]
