Clinical analysis of acute myocardial infarction caused by coronary embolism

Abstract

IntroductionAcute myocardial infarction (AMI) is very common in clinic, and is often caused by incomplete coronary occlusion or complete occlusion induced by acute plaque rupture (1). Coronary angiography plays an important role in the etiology diagnosis and treatment of AMI (2). In previous studies, 1-12% of patients with AMI who underwent coronary angiography did not develop an irregular lumen, or coronary artery stenosis of <50% (3,4). In this type of AMI, causes of infarct-related artery occlusion vary from person to person, such as increased platelet or coagulation activity (hypercoagulability) (5-7), coronary artery spasm (8), coronary artery embolism (9,10), as well as coronary myocardial bridge, coronary artery ectasia and coronary artery dissection (11). AMI caused by coronary artery embolism is rare in clinical practice. This study conducts an analysis of the clinical characteristics of these patients. MethodsFrom 2005 to 2015, five patients with AMI caused by coronary artery embolism were admitted to our hospital, and underwent primary percutaneous coronary intervention Original Article

Factor Xa Inhibition with Apixaban Does Not Influence Cardiac Remodelling in Rats with Heart Failure After Myocardial Infarction

“…Another mechanism by which the hypercoagulable state could contribute to the progression of HF is coronary microvascular embolization leading to MI [36,37]. Anticoagulants are often prescribed in HF patients without AF that are considered to be at high risk for stroke, such as those with an LV thrombus.…”

Myocardial Infarction in the Group of Patients With Atrial Fibrillation

“…По данным литературы, ассоциированные с ФП эмбологенные ИМ происходили в отсутствие АК или при недолжном контроле международного нормализованного отношения при применении варфарина [49]. Вопрос АТТ при данном типе ИМ у пациентов с ФП также остается открытым.…”

“…Вопрос АТТ при данном типе ИМ у пациентов с ФП также остается открытым. Некоторые эксперты считают, что необходим прием варфарина с одним антиагрегантом, другиечто достаточно только варфарина [28,49]. ПОАК при эмбологенных ИМ не исследовались.…”

Acute Myocardial Ischemia Secondary to Embolization of Left Atrial Myxoma to Coronary Artery

“…Acute myocardial infarction (AMI) is caused by non-atherosclerotic lesions in 1-12% subset of cases [ 1 ]. One such cause includes embolization [ 1 ]. Sources of embolization include a mural thrombus, a septic embolus secondary to infective endocarditis, valve calcification or from a left atrial myxoma [ 2 - 4 ].…”
