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.

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.

indicates inducible ischemia while an FFR above 0.80 excludes ischemia in 90% of cases. There is a strong correlation between FFR and inducible myocardial ischemia. It recalculates SYNTAX score by incorporating ischemia producing lesions determined by FFR. 2009 Jan 15;360(3):213-24. Normal FFR is 1.0 N Engl J Med.

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.

Chest Pain Severity Rating Is a Poor Predictive Tool in the Diagnosis of ST-Segment Elevation Myocardial Infarction [link] Abstract Current ST-segment elevation myocardial infarction (STEMI) guidelines require persistent electrocardiogram ST-segment elevation, cardiac enzyme changes, and symptoms of myocardial ischemia.

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.

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.
