Question

Myocardial stunning pattern not matching the ECG. What is the diagnosis.

• A. Takotsubo cardiomyopathy
• B. Restrictive cardiomyopathy
• C. Brigade's cardiomyopathy
• D. Pericardial something

Answer 1

The Correct Option is A

To determine the diagnosis based on the provided scenario, we need to recognize the unique clinical pattern. The question describes "myocardial stunning pattern not matching the ECG." This specific observation is characteristic of a certain condition in which the heart muscle exhibits temporary dysfunction without corresponding permanent damage on an ECG. Such a scenario is emblematic of:

Takotsubo cardiomyopathy

Explanation:

• Takotsubo cardiomyopathy, also known as stress-induced cardiomyopathy or "broken heart syndrome," is a condition where the heart's left ventricle experiences sudden temporary weakening commonly triggered by severe emotional or physical stress.
• This condition frequently presents with myocardial stunning without the permanent ECG changes typically seen in other myocardial infarctions. The ECG may show ST-segment elevation or T-wave inversion, which are not specific for anatomical distribution seen in coronary artery disease.
• The primary feature distinguishing Takotsubo cardiomyopathy is the mismatch between the degree of myocardial dysfunction observed and the changes on the ECG.

This explanation aligns with the distinctive clinical presentation provided. Therefore, the correct diagnosis is Takotsubo cardiomyopathy.
