用测定血浆肌酸激酶(CK)的连续变化来估计梗塞范围是评价预后及挽救缺血心肌措施的常用方法。梗塞范围酶法估计的可靠性已由尸检材料得到证实。然而,如果缺少较早期的CK测定,可致对梗塞范围的低估。本文目的是确定缺少早期CK值时对梗塞范围估计的影响,并提出校正方法。 Estimating the extent of infarction using a continuous change in plasma creatine kinase (CK) is a common method of evaluating prognosis and saving ischemic myocardium. The reliability of the enzymatic estimates of infarct size has been corroborated by autopsy material. However, the lack of an earlier CK assay can underestimate the infarct size. The purpose of this paper is to determine the impact of missing early CK values ​​on the estimation of infarct size and to propose a correction method.
