    • The present invention relates to a method of diagnosing if a subject which has suffered from an acute myocardial infarction is also suffering from a pre-existing myocardial dysfunction, the method comprising a) determining the amount of a natriuretic peptide in a sample of the subject; b) determining the amount of a cardiac troponin in a sample of the subject; c) calculating the ratio (natriuretic peptide/cardiac troponin); and d) diagnosing if the elevated natriuretic peptide level is related to a preexisting myocardial dysfunction or if the elevated level is caused by the acute myocardial infarction, based on the ratio calculated in step c). The method allows determining whether the individual has suffered from a myocardial dysfunction, in particular heart failure, before the myocardial infarction has occurred.
    • 本发明涉及一种诊断是否患有急性心肌梗死的受试者也患有预先存在的心肌功能障碍的方法,所述方法包括:a)确定受试者样品中利尿钠肽的量; b)确定受试者样品中心肌肌钙蛋白的量; c)计算比例(利钠肽/心肌肌钙蛋白); 以及d)基于在步骤c)中计算的比率来诊断升高的利尿钠肽水平是否与预先存在的心肌功能障碍相关,或者如果升高的水平是由急性心肌梗死引起的。 该方法允许在发生心肌梗死之前确定个体是否患有心肌功能障碍,特别是心力衰竭。
