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.

Background Out-of-hospital cardiac arrest (OHCA) has a poor prognosis. The optimal timing and role of early coronary angiography (CAG) in OHCA patients without ST-segment elevation remains unclear. The goal of this study is to compare an early CAG versus delayed CAG strategy in OHCA patients without ST elevation.

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 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).

I suspect this is Type 2 MI due to prolonged severe hypotension from cardiac arrest. If the arrest had another etiology (such as old scar), and the ST elevation is due to severe shock, then it is a type II STEMI. MINOCA: Myocardial Infarction in the Absence of Obstructive Coronary Artery Disease).
