This has important clinical significance , as many successfully lysed STEMI patient might have minimal segments of dissection/deep plaque fissures. , Spontaneous coronary dissection vs Iatrogenic dissection SCAD is a rare , different entity , enjoys a popular space in the patho-physiology of CAD. Is plaque fissure painful ?

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.

She had this ECG recorded: Obvious massive anterior STEMI She was quickly brought to the critical care area and the cath lab was activated. Here is the ECG at 25 minutes: Terrible LAD STEMI (+) OMI So a CT scan was done which of course showed a normal aorta. This was ruptured plaque with thrombus. She was a walk-in at triage.

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).

This is a troponin I level that is almost exclusively seen in STEMI. So this is either a case of MINOCA, or a case of Type II STEMI. If the arrest was caused by acute MI due to plaque rupture, then the diagnosis is MINOCA. I believe the latter (type II STEMI) is most likely. Troponin I rose to 44.1 FFR can be useful.

It is equivalent to a transient STEMI. Not much, but studies of STEMI and NonSTEMI show that about 70% of those diagnosed with STEMI have a peak troponin I above 10 ng/mL and that about 70% of those diagnosed with NonSTEMI have a peak troponin I below 10 ng/mL. What is Spontaneous Coronary Artery Dissection (SCAD)?
