I suspect this is Type 2 MI due to prolonged severe hypotension from cardiac arrest. If the arrest was caused by acute MI due to plaque rupture, then the diagnosis is MINOCA. 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.

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.
