O termo infarto do miocárdio (IM) agudo deve ser usado quando há evidência de necrose miocárdica em um contexto clínico consistente com isquemia miocárdica aguda. Nessas condições, qualquer um dos critérios a seguir atende ao diagnóstico de IM; _x000D_ Detecção de aumento e/ou queda de valores de biomarcadores cardíacos com pelo menos um valor acima do 99º percentil do limite de referência superior e com pelo menos um dos seguintes; _x000D_ a. Sintomas de isquemia. _x000D_ b. Novas ou supostamente novas alterações significativas de segmento ST-onda T (ST-T) ou novo bloqueio de ramo esquerdo (BRE) no eletrocardiograma (ECG). _x000D_ c. Desenvolvimento de ondas Q patológicas no eletrocardiograma (ECG). _x000D_ d. Evidência em exame de imagem de nova perda de miocárdio viável ou nova anormalidade de movimento de parede regional. _x000D_ e. Identificação de um trombo intracoronário por angiografia ou autópsia. _x000D_ _x000D_ _x000D_ Infarto de qualquer localização do miocárdio, ocorrendo dentro de 4 semanas (28 dias) a partir do início de um infarto anterior (OMS) | |||

The term acute myocardial infarction (MI) should be used when there is evidence of myocardial necrosis in a clinical setting consistent with acute myocardial ischemia. Under these conditions any one of the following criteria meets the diagnosis for MI; Detection of a rise and/or fall of cardiac biomarker values with at least one value above the 99th percentile upper reference limit and with at least one of the following; a. Symptoms of ischaemia. b. New or presumed new significant ST-segment-T wave (ST-T) changes or new left bundle branch block (LBBB)in the electrocardiogram (ECG). c. Development of pathologic Q waves in the electrocardiogram (ECG). d. Imaging evidence of new loss of viable myocardium or new regional wall motion abnormality. e. Identification of an intracoronary thrombus by angiography or autopsy. Infarction of any myocardial site, occurring within 4 weeks (28 days) from onset of a previous infarction (WHO) | |||
