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

…spasm may account for the ischaemia. STEMI usually results from rapid thrombotic occlusion of a previously atherosclerotic coronary artery. Slowly progressive severe stenoses are less…

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

…cardiologists – particularly interventional cardiologists – this knowledge is of critical importance as they must be able to directly pinpoint where the coronary artery occlusion is located…

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)

…acute total occlusion of an epicardial coronary artery (i.e. STEMI), pathological Q waves can develop already within 2 hours after the onset of infarction…

The ECG in assessment of myocardial reperfusion

…hours and such T waves are robust indicators of successful reperfusion (patent artery). This is also associated with better prognosis, return of R wave amplitudes…

Fourth Universal Definition of Myocardial Infarction: Types 1–5

…19th century first linked thrombotic occlusion of a coronary artery with myocardial necrosis. Although early clinical descriptions emerged at the dawn of the 20th century…

Cardiac thromboembolism: cardiac sources of embolism

…TIA (transient ischemic attack), coronary artery occlusion, and peripheral embolization. Stroke is the third leading cause of death in Western countries, and ultrasound studies are…

The Fourth Universal Definition of Myocardial Infarction: Types 1–5

…subepicardium over several hours. The extent and tempo of injury are influenced by collateral flow, myocardial oxygen consumption, and intermittent occlusion with reperfusion. Prompt reperfusion…
