“…Collateral flow to the infarct The infarct-related coronary artery was occluded in almost three-fourths of the cases; it was narrowed by >90% in the remaining patients. This finding confirms pathologic-anatomic studies in which the coronary artery was found to be stenosed by at least 70% (Arnett and Roberts, 1976;Chandler et al .. 1974). The prevalence of the LAD occlusion was probably due to selection, inasmuch as patients with large infarction were preferably studied, and the LAD generally has the largest perfusion area.…”

“…Although the majority of the cases of acute myocardial infarction is caused by atherosclerotic coronary artery disease, acute myocardial infarction can occur in people with coronary arteries that appear normal or nearly normal in an angiography (2). The pathogenetic mechanism of myocardial infarction in patients with normal arteries remains unknown.…”

“…Embora não possamos afastar a possibilidade da presença de pequenas placas ateroscleróticas coronárias, achamos pouco provável a participação das mesmas neste processo, já que precisaríamos acreditar que mais de uma placa tenha se instabilizado ao mesmo tempo ou que o trombo coronário oriundo de uma delas tenha sido responsável pela embolização retrógrada das outras. Para explicar o infarto agudo do miocárdio (IAM) com artérias normais, inúmeros modelos fisiopatológicos [1][2][3][4][5] foram propostos, porém o enigma não foi totalmente desvendado, ficando o espasmo arterial e a agregação plaquetária com conseqüente trombose coronária, seguida de lise e reperfusão, as causas mais prováveis. A trombose coronária em artérias angiográficas normais [6][7][8] , embora não rara, quando presente em múltiplos vasos é incomum 9 , o que torna único o caso relatado.…”
