A 60-something woman presented after a witnessed cardiac arrest. This is commonly found after epinephrine for cardiac arrest, but could have been pre-existing and a possible contributing factor to cardiac arrest. Final Diagnosis: Cardiac Arrest due to Torsades from long QT of unknown etiology.

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?

In the ISCHEMIA (International Study of Comparative Health Effectiveness with Medical and Invasive Approaches) trial, researchers examined the risk of ischemic events in patients with stable coronary artery disease. years, with 57.1% occurring within 30 days after CABG.

It is apparently fortunate that she had a cardiac arrest; otherwise, her ECG would have been ignored. 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.

Heart Valve Disease If one or more heart valves are not functioning correctly, it can cause blood to flow backward, putting extra pressure on the heart, which may cause it to expand to compensate for the inefficiency. This may result in ischemia (lack of oxygen to the heart muscle), causing parts of the heart to weaken and enlarge.

The first task when assessing a wide complex QRS for ischemia is to identify the end of the QRS. The ST segment changes are compatible with severe subendocardial ischemia which can be caused by type I MI from ACS or potentially from type II MI (non-obstructive coronary artery disease with supply/demand mismatch).
