Abstract 087: Cocaine?Induced Acute Spinal Cord Ischemia Syndrome

Stroke: Vascular and Interventional Neurology

IntroductionAcute spinal cord ischemia syndrome (ASCIS) is a rare disease that is thought to comprise roughly only 1.2% A diagnostic spinal angiogram was completed with no evidence of arteriovenous fistula or aortic dissection. Stroke: Vascular and Interventional Neurology, Volume 3, Issue S2 , November 1, 2023. of all strokes [1, 2].

Many of the changes seen are reminiscent of LVH with “strain,” and downstream Echo may very well corroborate such a suspicion, but since the ECG isn’t the best tool for definitively establishing the presence of LVH, we must favor a subendocardial ischemia pattern, instead. Type I ischemia. Type II ischemia.

It should be known that each category can easily manifest the generic subendocardial ischemia pattern. In general, subendocardial ischemia is a consequence of global supply-demand mismatch that usually ameliorates upon addressing, and mitigating, the underlying cause. What’s interesting is that the ECG can only detect ischemia.

FFR is obtained by dividing the pressure distal to the stenosis by the central aortic pressure, which is usually equal to the pressure proximal to the stenosis if there is no additional stenosis in between. indicates inducible ischemia while an FFR above 0.80 excludes ischemia in 90% of cases. Normal FFR is 1.0 An FFR below 0.75

His response: “subendocardial ischemia. Smith : It should be noted that, in subendocardial ischemia, in contrast to OMI, absence of wall motion abnormality is common. With the history of Afib, CTA abdomen was ordered to r/o mesenteric ischemia vs ischemic colitis vs small bowel obstruction. Anything more on history?

There is ventricular hypertrophy in the absence of abnormal loading conditions, such as aortic stenosis, or hypertension, for example – of which the most common variant is Asymmetric Septal Hypertrophy. There is LBBB-like morphology with persistent patterns of subendocardial ischemia. References Naidu, S.

A teenager with chest pain, a troponin below the limit of detection, and "benign early repolarization"

Dr. Smith's ECG Blog

CT angiogram chest: no aortic dissection or pulmonary embolism. This may occur as a result of blunt chest trauma or other acute stress that produces a sudden extreme shear force on a coronary artery ( that can result in an intimal tear that leads to intraluminal thrombosis ). No further troponins were measured. Was this coincidence? —
