Creatine kinase (CK) and hexose phosphate isomerase (PHI) activities were determined in 36 samples of human heart muscle obtained from patients during cardiovascular surgery. With one exception, CK activities were higher than any reported so far in the literature (papillary muscle, left ventricle: 2,521 +/- 776 IU/g wet weight at 37 degrees C). PHI Activities, the first time measured, are comparable to those in skeletal muscle (200-400 U/g, higher in papillary muscle than in the right auricle). The activities of both enzymes determined correlate significantly (all samples considered together: r = 0.773; p < 0.001). Results are discussed with respect to their possible clinical interest as well as their significance for myocardial metabolism.
在心血管手术期间从患者获取的36份人心肌样本中测定了肌酸激酶（CK）和磷酸己糖异构酶（PHI）的活性。除一个样本外，CK活性高于迄今文献报道的任何值（乳头肌、左心室：37℃时湿重为2,521±776 IU/g）。首次测定的PHI活性与骨骼肌中的活性相当（200 - 400 U/g，乳头肌中的活性高于右心耳）。所测定的两种酶的活性显著相关（综合考虑所有样本：r = 0.773；p < 0.001）。讨论了这些结果在可能的临床意义以及对心肌代谢的重要性方面的情况。
