DISCUSSION: The 12-lead EKG EMS initially obtained for this patient showed severe ischemia, with profound "infero-lateral" ST depression and reciprocal ST elevation in lead aVR. The ECG cannot diagnose the etiology of ischemia; it only the presence of ischemia, from whatever etiology. NEJM 362(9):779; March 4, 2009.

Mechanism is thought to be due to sustained sympathetic stimulation, probably caused by dysfunction of insular cortex resulting in reversible neurogenic damage to the myocardium which could include contraction bands and subendocardial ischemia [2]. 2009 Nov;40(11):3478-84. Epub 2009 Aug 27. doi: 10.1161/STROKEAHA.109.556753.

Precordial ST depression may be subendocardial ischemia or posterior STEMI. I have warned in the past that one must think of other etiologies of ischemia when there is tachycardia. Whether it is subendocardial ischemia or posterior STEMI, if you cannot get it to resolve, you must activate the cath lab. There is no ST elevation.

Reference : Apart from the heavily quoted classics of COURAGE, BARI-2D, ISCHEMIA, ORBITA 1 etc. Regular exercise equivalent to PCI (ESC 2009).Will Please note ORBITA -2 is not an antidote to ORBITA-1) ,Read this 1.AVERT AVERT study :Atorvastatin equals PCI.2.Regular Will try to get the link for this soon.

Learning Point: Concordant ST segment elevation can arise from profound ischemia triggered by ventricular tachycardia (VT), or it may represent an exaggerated basal ST change accompanying tachycardia. The patient rapidly regained consciousness, reporting no residual pain. A peak troponin level of 70 ng/L was observed.

Though this association may be related to impaired cerebral oxygen delivery, it is unclear whether these changes relate to cerebral ischemia. Patients who had a brain MRI and serial hemoglobin measurements were included.

We explored whether major ABO incompatible platelet transfusions are associated with these ischemic lesions.Methods:Consecutive spontaneous ICH patients enrolled into a single-center, prospective cohort study between 2009 and 2016 were assessed. Major ABO incompatible platelet transfusion was the exposure. 217.94, p = 0.03).Conclusions:Major
