Large Coronary Artery Aneurysm with Thrombotic Coronary Occlusion Resulting in ST-Elevation Myocardial Infarction After Warfarin Interruption

The patient had been on oral anticoagulant therapy (warfarin) from the first thrombotic event, but the medication had been recently changed to aspirin 4 months before the second event. Emergent coronary angiography revealed thrombotic total occlusion of RCA with heavy thrombotic burden from middle RCA to the ostium of the posterior descending branch. Combination pharmacotherapy was performed with anticoagulants (heparin), fibrinolytics (urokinase), and Glycoprotein IIb/IIIa antagonists (abciximab), in addition to mechanical thrombosuction. However, on hospital day 2, the patient complained recurrent chest pain and again underwent coronary angiography, which revealed distal embolization of large thrombus to the posterior lateral branch. Coronary flow was recovered after repeated mechanical thrombosuction was performed. This case has shown the importance of aggressive combination drug therapy, accompanied by mechanical thrombosuction in patient with myocardial infarction due to thrombotic occlusion of coronary artery aneurysm and the importance of unceasing life-long anticoagulant therapy in those particular patients. -

Karrer Senior Thesis presented to the College of Medicine, University of Nebraska Omaha, 1938. 480947 INTRODUCTION The terms coronary thrombosis, coronary occlusion, and cardiac or myocardial infarction are often em- ployed as synonyms, although there are useful differences in their meanings. In this thesis the author will deal only with that special type of coronary occlusion in which coronary thrombosis is the final event in the process of occlusion. Also, the thesis will be limited, more or less, to that type of thrombosis which is acute thrombosis of a coronary artery, rather than to the chronic type which is neither as spec tacular a disease nor as clean cut in its clinical picture. The definition of coronary thrombosis as given by Dorland {1935} is, "The formation of a clot in a branch of the coronary arteries which supply blood to the heart muscle, resulting in obstruction of the artery and infarction of the area of the heart supplied by the occluded vessel." Cecil (1935) modifies the definition in that he mentions the obstruction is generally acute. -

A cluster of neonatal myocardial infarction cases Neonatal coronary thrombosis was observed, leading to an investigation of causes and contributors. We performed a single-center review of neonates >37 weeks between 2011 and 2017 to identify neonates with myocardial infarction. Neonates with prior cardiac surgery, congenital anomalies of the coronaries, or sepsis were excluded. Diagnosis of MI was based on ECG changes, elevated troponin, decreased function or regional wall abnormality, and abnormal coronary angiography. -
Acute Thrombosis of Double Major Coronary Arteries Associated with Amphetamine Abuse
Case Reports Acta Cardiol Sin 2007;23:268-72 Acute Thrombosis of Double Major Coronary Arteries Associated with Amphetamine Abuse Wei-Ren Lan, Hung-I Yeh, Charles Jia-Yin Hou and Yu-San Chou Drug-induced acute myocardial infarction is not a common phenomenon. The underlying mechanism in the majority of such patients has been related to coronary spasm, including in those with amphetamine abuse, in whom the coronary arteriogram was always found normal. We report a 30-year-old male amphetamine abuser with acute myocardial infarction owing to acute thrombosis of the left anterior descending coronary artery and left circumflex coronary artery. We postulate a relationship between the use of amphetamine and occurrence of acute thrombosis of multiple major coronary arteries.

The examination will be conducted in English. Faculty examiner: Professor Gunnar Gislason (Department of Cardiology, Copenhagen University Hospital Gentofte, Copenhagen, Denmark). Abstract Batra, G. 2017. Atrial Fibrillation in the setting of Coronary Artery Disease. Risks and outcomes with different treatment options. Digital Comprehensive Summaries of Uppsala Dissertations from the Faculty of Medicine 1332. 86 pp. Uppsala: Acta Universitatis Upsaliensis. ISBN 978-91-554-9917-4. Coronary artery disease (CAD) is the leading cause of mortality worldwide and atrial fibrillation (AF) is a prevalent arrhythmia associated with increased risk of mortality and morbidity. Despite improved outcome in both diseases, there is a need to further describe the prevalence, outcome and management of CAD in patients with concomitant AF. AF was a common finding among patients with MI, with 16% having new-onset, paroxysmal or chronic AF. Patients post-MI with concomitant AF, regardless of subtype, were at increased risk of composite cardiovascular outcome of mortality, MI or ischemic stroke, including mortality and ischemic stroke alone. No major difference in outcome was observed between AF subtypes. At discharge, an oral anticoagulant was prescribed to 27% of the patients with MI and AF undergoing percutaneous coronary intervention (PCI).
