Introduction The use of contemporary drug-eluting stents (DES) has significantly improved outcomes of patients with coronary artery disease (CAD) undergoing percutaneous coronary intervention (PCI). Patients with left main (LM) disease, cardiogenic shock (CS), or severely reduced left-ventricular ejection fraction (LVEF) were excluded.

A man in his 70s with past medical history of hypertension, dyslipidemia, CAD s/p left circumflex stent 2 years prior presented to the ED with worsening intermittent exertional chest pain relieved by rest. The baseline ECG is basically normal with no ischemia. In my opinion, I think it looks more like subendocardial ischemia.

The axiom of "type 1 (ACS, plaque rupture) STEMIs are not tachycardic unless they are in cardiogenic shock" is not applicable outside of sinus rhythm. In some cases the ischemia can be seen "through" the flutter waves, whereas in other cases the arrhythmia must be terminated before the ischemia can be clearly distinguished.

The patient has also developed sinus bradycardia, which may result from right coronary artery ischemia to the SA node. The patient is started on epinephrine infusion for cardiogenic shock and cardiology took the patient to the cath lab. Two stents were placed with resultant TIMI 3 flow.

Similarly, STEMI guidelines call for urgent angiography for refractory ischemia or electrical/hemodynamic instability, regardless of ECG findings. So there is now high pre-test probability + refractory ischemia + Modified Sgarbossa + dynamic ECG changes. So the RCA was stented. Learning points 1.

The patient was referred immediately for cath which revealed RCA occlusion that was stented. Remember, in diffuse subendocardial ischemia with widespread ST-depression there may b e ST-E in lead s aVR and V1. There are well formed R-waves with good voltage/amplitude which is uncommon for ischemia. There is ST depression in V1.

Now appears to be in cardiogenic shock." This is ischemia until proven otherwise. However, cardiogenic shock usually takes some time to develop, so it is probably subacute." Cardiogenic shock and ACS is an indication for the cath lab, even if you don't think there is OMI. I was texted these ECGs.
