Background To investigate the correlation between lg (circSCMH1/miR-874) and acute coronary syndrome (ACS), acute myocardial infarction (AMI), and carotid plaque stability. Methods 701 patients were divided into stable coronary artery disease (SCAD), ACS, and control groups.

Here’s the angiogram of the RCA : No thrombus or plaque rupture in the RCA (or any coronary artery) was found. This MI wasn’t caused by a ruptured plaque of CAD - it was a coronary artery dissection of the RCA. In the absence of these factors it is termed spontaneous coronary artery dissection ( SCAD ). A study by Hassan et al.

If the arrest was caused by acute MI due to plaque rupture, then the diagnosis is MINOCA. MINOCA: Myocardial Infarction in the Absence of Obstructive Coronary Artery Disease). Here is my comment on MINOCA: "Non-obstructive coronary disease" does not necessarily imply "no plaque rupture with thrombus." FFR can be useful.

The ECG is diagnostic for acute transmural infarction of the anterior and lateral walls, with LAD OMI being the most likely cause (which has various potential etiologies for the actual cause of the acute coronary artery occlusion, the most common of which is of course type 1 ACS, plaque rupture with thrombotic occlusion).

I asked Angie Lobo ( [link] ), a third year intermal medicine resident at Abbott Northwestern Hospital (and Minneapolis Heart Institute) and an aspiring cardiologist, to write a couple paragraphs on SCAD.
