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

…artery (LMCA) occlusion is a rare but catastrophic manifestation of acute coronary syndromes. The LMCA supplies a large myocardial territory through the left anterior descending…

Vulnerable Plaque and Mechanisms of Acute Coronary Occlusion

…hypertension with or without left ventricular hypertrophy. Among patients with NSTE ACS undergoing angiography, approximately 10% have no critical epicardial stenosis. In some of these…

Posterior acute myocardial infarction (STEMI)

…larger R waves, which are reciprocal to posterior Q waves. As mentioned above, posterior myocardial infarction may be accompanied by inferior infarction if the occlusion…

Ischemic Cardiomyopathy: Myocardial Viability Assessment and Revascularization

…encompasses several physiological states. Brief coronary occlusion or relatively prolonged moderate ischemia may produce post ischemic stunning. In the absence of infarction, contractile recovery can…

ST-Elevation Myocardial Infarction Complicated by Cardiogenic Shock

…abrupt reduction in coronary blood flow caused by thrombotic occlusion of a previously atherosclerotic artery. Plaque erosion or rupture exposes thrombogenic material to circulating blood…

Pulmonary Embolism (PE)

…and form of the thrombus, it will occlude the main pulmonary artery or its branches. The larger the thrombus, the more proximal the occlusion and…

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

…the conventional 12 lead ECG. These situations are as follows: Transmural ischemia located in the posterolateral portion of the left ventricle . Transmural ischemia located in…

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

…alleviate ischemic chest pain may lead to hemodynamic collapse in patients with right ventricular ischemia or infarction. Recognizing ECG signs of right ventricular involvement is…

Cardiac thromboembolism: cardiac sources of embolism

…a cerebral artery is occluded due to local atherothrombosis or occlusion due to embolization. Approximately 30% of all ischemic strokes are caused by cardiac embolism…

The left ventricle in myocardial ischemia and infarction

…a proximal occlusion (in the RCA) which cuts off blood flow to the right ventricle, will also affect the inferior wall of the left ventricle…
