Written by Jesse McLaren A 70 year old with prior MIs and stents to LAD and RCA presented to the emergency department with 2 weeks of increasing exertional chest pain radiating to the left arm, associated with nausea. I sent this to the Queen of Hearts So the ECG is both STEMI negative and has no subtle diagnostic signs of occlusion.

reports MI in 2001 with a stent placed in the "marginal" artery. First, this patient had a known stent in the "marginal" artery and thought he was having a heart attack. By definition, this is a non-STEMI because there is not 1 mm of ST elevation in 2 consecutive leads. Fortunately, his MI was not large by biomarkers.

Considering their multidirectional effect on atherosclerosis, new inflammatory biomarkers integrating various leukocyte subgroups have been proposed to calculate the systemic inflammatory response index (SIRI) and systemic inflammatory index (SII).Aim:The All patients had interventional PCI with balloon and stent insertion.

Step 1 to missing posterior MI is relying on the STEMI criteria. A prospective validation of STEMI criteria based on the first ED ECG found it was only 21% sensitive for Occlusion MI, and disproportionately missed inferoposterior OMI.[1] But it is still STEMI negative. A 15 lead ECG was done (below). In a study last year, 14.4%

The "criteria" for posterior STEMI are 0.5 Is it STEMI or NonSTEMI? It was opened and stented with a door to balloon time of about 120 minutes (this is long for STEMI, but very short for a high risk Non STEMI). The troponin I returned at 4.1 ng/mL (ULN = 0.030 ng/mL) , diagnostic of myocardial injury.

Recall from this post referencing this study that "reciprocal STD in aVL is highly sensitive for inferior OMI (far better than STEMI criteria) and excludes pericarditis, but is not specific for OMI." The ESC states that patients with suspected ACS should go to the cath lab in ＜2 hours "regardless of ECG or biomarker evidence of MI!!"

In acute STEMI, the T-wave is large, whereas in LV aneurysm , the T-wave is not so large. If greater than or equal to 0.22 , then acute anterior STEMI. correlates with anterior STEMI) Rule 2. If there is any one lead of V1-V4 with a T/QRS ratio greater than 0.36, then it is likely to be anterior STEMI. Answer below.
