Two more Cases of Takotsubo Stress Cardiomyopathy

Posted Dec 20 2010 4:08pm
Case 1.

This is the ECG of a 50 yo old woman who collapsed, was found to have a pulse, but then found to be in ventricular tachycardia. She was shocked into sinus rhythm. She presented to the ED comatose.

There is marked ST elevation especially in leads V3 to V6, as will as limb leads I and II, with no reciprocal ST depression. The cath lab was activated for STEMI, but the patient had clean coronaries. Before initiating therapeutic hypothermia, a head CT was done and showed fatal subarachnoid hemorrhage.

Case 2.

This 81 yo was found comatose.
There is ST elevation in V1-V3 with hyperacute T-waves and Q-waves in V2 and V3. This is highly suspicious for acute anterior STEMI. However, she was found to have a fatal pontine hemorrhage and had a maximum troponin I, at 12 hours after presentation, of 2.0 ng/ml. Echocardiogram showed an anteroapical wall motion abnormality. In this case, since no angiogram was done, it is not proven that she did not have a simultaneous anterior STEMI, but with a low maximum troponin and alternative explanation, it is highly unlikely.
These cases demonstrate that SCM can present with STEMI pseudoinfarction patterns.
