In the chronic setting post-STEMI, LGE cardiac MRI is best used to detect replacement fibrosis (ie, final infarct size after injury healing). Finally, native T1 mapping has recently emerged as a contrast material-free method to measure infarct size …

2024年4月7日 · We report a case of MI diagnosed by cardiac MRI without an obvious culprit lesion on initial angiography in a patient that presented with STEMI on ECG. A 38-year-old male with no prior known CAD presented for chest pain. ECG revealed lateral STEMI complicated by V-fib arrest requiring defibrillation.

2025年1月31日 · Advances in MRI have made it possible to assess myocardial infarction in patients with acute chest pain as well as those with subacute or chronic disease. Using different MR signals and techniques provides valuable information on assessing scar tissue as well as salvageable myocardium.

Using cardiac magnetic resonance imaging (cMRI), we have reported that in patients who had a myocardial infarction (MI), having a wrap-around LAD was related to an apical wall infarction and a higher incidence of heart failure and stroke, regardless of the overall infarct size .

2021年8月24日 · Cardiac MRI is a noninvasive diagnostic tool using nonionizing radiation that is widely used in patients with ST-segment elevation myocardial infarction (STEMI). Cardiac MRI depicts different prognosticating components of myocardial damage such as edema, intramyocardial hemorrhage (IMH), microvascular obstruction (MVO), and fibrosis.

CMR has the unique ability to assess global and regional LVfunction post-MI, quantify infarct size with late gadolinium enhancement, assess the status of the microvasculature by identifying microvascular obstruction (MO, and evaluate the area at risk with T2-weighted imaging of myocardial edema.

ST-segment elevation myocardial infarction (STEMI) outcomes are influenced by the location of the culprit vessel with worse outcomes portended with a left anterior descending (LAD) culprit lesion. However, relatively little is known about the independent association of LAD involvement with clinical outcomes of patients with STEMI with and ...

2022年5月10日 · Simultaneous thrombosis in more than one coronary artery is an uncommon angiographic finding in patients with acute ST-segment elevation myocardial infarction. It is difficult to identify using 12-lead electrocardiography and usually leads to cardiogenic shock and fatal outcomes, including sudden cardiac death.

2015年5月15日 · Acute myocardial infarction is the most common cause of mortality in developed countries. 1 Patients with anterior ST-segment elevation myocardial infarctions (STEMIs) that are caused by left anterior descending coronary artery (LAD) occlusions are at greatest risk for adverse clinical outcomes. 2, 3, 4 LAD occlusion is one of the strongest ...

2024年2月21日 · Materials and methods: Patients with post-anterior STEMI who received primary percutaneous coronary intervention underwent contrast cardiac magnetic resonance imaging (MRI) during acute (5-9 days post-STEMI) and chronic (at 6 months) phases. The LADSS was categorized into three groups: Groups 1, 2, and 3 representing positive, flat, and ...
