A patient had a cardiacarrest with ventricular fibrillation and was successfully defibrillated. COACT: The COACT trial was fatally flawed, and because of it, many cardiologists are convinced that if there are no STEMI criteria, the patient does not need to go to the cath lab. These studies did not address OMI ECG findings!!!
This 80 year old with a history of CABG had a cardiacarrest. This is as clear a STEMI as you can get. Now, it is true that shortly after a non-ACS cardiacarrest, there can be transient diffuse ST depression, but not ST elevation in a coronary distribution, and there should not be a wall motion abnormality.
Note that they finally have laid to rest the new or presumably new LBBB as a criteria for STEMI. Note that they finally have laid to rest the new or presumably new LBBB as a criteria for STEMI. Also note that they allow ST depression c/w posterior MI to be a STEMI equivalent. What is the utility of a head CT in cardiacarrest?
ST depression is common BOTH after resuscitation from cardiacarrest and during atrial fib with RVR. Again, it is common to have an ECG that shows apparent subendocardial ischemia after resuscitation from cardiacarrest, after defibrillation, and after cardioversion. Academic Emergency Medicine 17(s1):S194; May 2010
ECG met STEMI criteria and was labeled STEMI by computer interpretation. J waves can also be induced by Occlusion MI (5), STEMI mimics including takotsubo and myocarditis complicated by ventricular arrhythmias (6, 7), and subarachnoid hemorrhage with VF (8). Take home : Not all STEs are STEMIs or OMIs. What do you think?
