Posterior acute myocardial infarction (STEMI)

…NSTEMI) since they present with ST segment depressions on the 12 lead ECG (recall that ST segment depression is the hallmark of NSTE ACS/NSTEMI…

ST elevation myocardial infarction (STEMI) without ST elevations on 12-lead ECG

…occur simultaneously (if both territories are affected by the same artery occlusion). Approximately 30% of patients with posterolateral infarction will also have right ventricular infarction…

ECG manifestations of left main coronary artery (LMCA) occlusion and critical stenosis

…including acute occlusions, subtotal stenoses, and discusses associated clinical presentations, prognostic implications, and management strategies. In the GRACE ECG substudy of 5000 patients with non…

Vulnerable Plaque and Mechanisms of Acute Coronary Occlusion

…ischemia and infarction Definition and conceptual framework Acute coronary occlusion is the abrupt or progressive reduction of coronary blood flow sufficient to produce myocardial ischaemia…

ECG localization of myocardial infarction / ischemia and coronary artery occlusion (culprit)

…artery occlusion is located. The term culprit – which means "the guilty one" – is used to denote the occluded coronary artery. In the majority of cases…

A New Approach to Acute Coronary Syndromes: Occlusion MI (OMI) vs. Non-Occlusion MI (NOMI)

…reperfusion therapy. This approach fails to identify a substantial proportion of patients with acute coronary occlusion (ACO) who present without diagnostic ST elevation, often resulting…

Classification of Acute Coronary Syndromes (ACS) & Acute Myocardial Infarction (AMI)

…is caused by partial occlusion of the artery (i.e. coronary blood flow is not completely obstructed). NSTE ACS typically presents with ST segment depressions…

Interpretation of ECG after ROSC (Return of Spontaneous Circulation)

…waves) do not affect the management of cardiac arrest. Recurrent VT or VF after ROSC in a patient with a coronary risk profile should lead…

The ECG in assessment of myocardial reperfusion

…microcirculation. Indeed, studies show that 15–35% of patients with STE ACS/STEMI have inadequate microvascular flow despite patent epicardial blood flow. In such cases…

Fourth Universal Definition of Myocardial Infarction: Types 1–5
