What is the relationship between AST/TGO and myocardial infarction?
I - AST levels are almost always elevated after acute myocardial infarction.
II - The sensitivity and specificity of AST dosage in the diagnosis of acute myocardial infarction are high.
III - AST levels begin to rise 6 to 12 hours after chest pain and peak between 24 and 48 hours.
IV - AST levels return to reference values after the 5th or 6th day after chest pain.
a) Only I and II are correct.
b) Only II and III are correct.
c) Only III and IV are correct.
d) I, II and III are correct.
e) I, III and IV are correct.

A relação entre AST/TGO e infarto do miocárdio é que os níveis de AST quase sempre estão elevados após o infarto agudo do miocárdio. A sensibilidade e especificidade da dosagem de AST no diagnóstico do infarto agudo do miocárdio são altas. Os níveis de AST começam a aumentar de 6 a 12 horas após a dor no peito e atingem o pico entre 24 e 48 horas. Os níveis de AST retornam aos valores de referência após o 5º ou 6º dia após a dor no peito. Portanto, a alternativa correta é a letra d) I, II e III estão corretas.
