急性冠状动脉综合征已成为严重危害人类健康的重要致死病因,它的早期预测及预防其进展,对它的发生率、致残率、病死率的降低具有重要意义。心型脂肪酸结合蛋白作为心肌损伤标志物,具有较高的心肌特异性,对于诊断早期急性冠状动脉综合征具有较高的敏感性和良好的特异性,更适合于临床急性冠状动脉综合征的早期诊断,对于心肌损伤诊断的准确性和及时性都会有极大的提高。 Acute coronary syndrome has become an important lethal cause of serious harm to human health. Its early prediction and prevention of its progress are of great importance to its incidence, disability and mortality. Cardiac fatty acid-binding protein as a marker of myocardial injury, with high myocardial specificity, for the diagnosis of early acute coronary syndrome with high sensitivity and good specificity, more suitable for clinical early stage of acute coronary syndrome Diagnosis, diagnosis of myocardial injury accuracy and timeliness will be greatly improved.
