By Magnus Nossen This ECG is from a young man with no risk factors for CAD, he presented with chest pain. ACS then becomes less likely. Before the lab values returned this patient had a n emergent coronary CT angiogram done that ruled out CAD. Each main coronary artery (LAD, RCA and LCx) are shown in separate images.

The ECG is just a test: a Bayesian approach to acute coronary occlusion If a patient with a recent femur fracture has sudden onset of pleuritic chest pain, shortness of breath, and hemoptysis, the D-dimer doesn’t matter: the patient’s pre-test likelihood for PE is so high that they need a CT. A Bayesian approach to acute coronary occlusion.

Post by Smith and Meyers Sam Ghali ( [link] ) just asked me (Smith): "Steve, do left main coronary artery *occlusions* (actual ones with transmural ischemia) have ST Depression or ST Elevation in aVR?" Furthermore, among 35 patients with acute left main coronary artery occlusion, 9 presented with RBBB (mostly with LAFB) on the admission ECG.

Furthermore, there was no family history of early CAD, MI, or sudden cardiac death. Cardiology admitted him for observation with plans for next-day coronary angiogram. He reported to EMS a medical history of GERD only. The physical exam was unremarkable for diaphoresis or pallor, and he denied any episodes of vomiting. 1] Driver, B.

The biphasic T wave is consistent with recent reperfusion of an occluded coronary artery supplying the inferior region. 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.

Just because you don't see hemodynamically significant CAD on angiogram does not mean it is not OMI. An angiogram is a "lumenogram;" most plaque is EXTRALUMINAL!!

She had zero CAD risk factors. Now you have ECG and troponin evidence of ischemia, AND ventricular dysrhythmia, which means this is NOT a stable ACS.

But it does prove that the patient has coronary disease and makes the probability that his chest pain is due to ACS very very high. It is proven better than angiography alone in stable angina , and also has been shown to improve decisions on stenting non-culprit lesions in ACS. It could be acute, though probably is not.

If this is ACS with Aslanger's pattern , the ST depression vector of subendocardial ischemia (due to simultaneous 3 vessel or left main ACS) is directed toward lead II (inferior and lateral). Thus, this apparently is Aslanger's Pattern (inferior OMI with single lead STE in lead III, with simultaneous subendocardial ischemia).

The diagnostic coronary angiogram identified only minimal coronary artery disease, but there was a severely calcified, ‘immobile’ aortic valve.

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. This case represents the same physiologic event as OMI in terms of the result on the myocardium, therefore with identical ECG features, however there may not be ACS!
