Abstract
Atrial fibrillation is a common entity and can be associated with thromboembolic complications as many as 18% of patients per year. A coronary thromboembolus with subsequent myocardial infarction, however, is rare. We conducted a retrospective descriptive study of 12 patients hospitalized for myocardial infarction with angiographically normal coronary arteries and atrial fibrillation. This study aims to investigate the epidemiological, clinical, and prognostic factors. We conclude that the prevalence of these ACS was 0.56%. The average age was 57 years with a female predominance. Family history of early coronaropathy was the most frequently risk factor (33%), followed by Smoking (16%), dyslipidemia (16%), obesity (16%) and hypertension (8%). Diabetes was not found in any patient. These patients had an ST elevation myocardial infarction (STEMI) in 16% of cases vs 84% without ST elevation MI. The lateral location was the most prevalent in 41% of cases. The mean peak of troponin was 8.6ng/ml. The left ventricular dysfunction was detected in 5 cases. The echocardiography showed a case of mitral valve prosthesis dysfunction, a case of hypertrophic cardiomyopathy. Aortic and mitral valvulopathy was detected in 5 cases and an excellent hemodynamic profile was found in two cases. The trans esophageal echocardiography showed 5 cases of left intra auricular thrombus. The coronarography was normal in all patients. They received the basic treatment of acute coronary syndrom. Atrial fibrillation wasn’t tolerate in one case requiring pharmacologic cardioversion with good evolution. Hyperthyroidism was detected in two patients and required antithyroid therapy. Coronary artery thromboembolism as a nonatherosclerotic cause of acute coronary syndrom is a rare finding with unknown prevalence. The cardiologist should be aware of possible coronary artery embolism when the angiographic images are typical together with important thromboembolic risk factors.
