Angiogram No obstructive epicardial coronary artery disease Cannot exclude non-ACS causes of troponin elevation including coronary vasospasm, stress cardiomyopathy, microvascular disease, etc. This suggests further severe ischemia. hours T-wave are getting larger again The patient went for an angiogram at about 7 hours after arrival.

Subsequent testing supported the presumption of apical cardiomyopathy as the cause of this patient's sustained VT. CT coronary angiogram showed no obstructive coronary disease. Today's case is illustrative because it shows how high troponin may rise despite the absence of acute coronary occlusion! (

by making it clear to everyone that this is NOT an EKG that one sees with takotsubo cardiomyopathy. Hospital Course The patient was taken emergently to the cath lab which did not reveal any significant coronary artery disease, but she was noted to have reduced EF consistent with Takotsubo cardiomyopathy.

Physicians initially attributed symptoms to “panic, anxiety or stress” in half of these patients, with women more likely than men to have their symptoms attributed to psychiatric causes (65% vs. 32%; P < 04). == MY Comment by K EN G RAUER, MD ( 9/7/2020 ): == Interesting case with thorough discussion by Dr. Smith on arrhythmia management.

Weren't you taught that "new tall T wave in V1" is concerning for ischemia, and so this is the opposite? As always, Takotsubo stress cardiomyopathy and focal myocarditis are rare possibilities which can only be proven after a negative cath. Weren't you taught that concave morphology favors pericarditis? What do you think?

2020) The un-disputable fact is ischemic DCM has a target to treat, though it is termed as cardiomyopathy. The simple reason could be we can address the ischemia a potential arrhythmic target by some form of revascularization in IDCM. The second reason is, NDCM is a progressive primary muscle disease.

There is no evidence of infarction or ischemia. The absence of any wall motion abnormality makes ischemic cardiomyopathy very unlikely. The new onset cardiomyopathy was thought to be due to both drug/alcohol use and to Tachycardia-Induced Cardiomyopathy. There are nonspecific ST-T abnormalities.

Such findings would normally suggest primary ischemia with concomitant surveillance of coronary occlusion, but these ST/T changes might very well be secondary to the Escape mechanism at hand. LBBB is typically the result of preexisting hypertrophy, ischemic heart disease, or cardiomyopathy. 5] Isnard, R. & Pousset, F.
