近年,恶性肿瘤有增加趋势,并且由于治疗的进步,恶性肿瘤病人寿命延长,肿瘤向各脏器的转移也在增加。过去,心脏转移瘤的发生率不高,但由于上述原因目前有增加的倾向,只是生前诊断心脏转移瘤是困难的。作者于1963年至1980年的18年间,连续观察剖检的1,392例中,恶性肿瘤为525例,其中向心脏转移的有64例。年龄5～81岁,平均为58.8岁。男43例,女21例。64例中肉眼可见的转移瘤有45例,显微镜下才可见到的转移有19例。对于这些病例,在临床方面研究了转移时的症状,以及心电图的变化;在病理学方 In recent years, there has been an increasing trend in malignant tumors, and due to the advancement of treatment, the life expectancy of malignant tumor patients has prolonged, and the transfer of tumors to various organs has also increased. In the past, the incidence of cardiac metastases was not high, but due to the above reasons there is currently a tendency to increase, but it is difficult to diagnose the heart metastases before its lifetime. During the 18 years from 1963 to 1980, of 1,392 consecutive necropsy cases, 525 were malignant, of which 64 were metastasized to the heart. Age 5 to 81 years old, average 58.8 years old. 43 males and 21 females. Of the 64 cases, 45 were metastases that were visible to the naked eye, and 19 were seen under the microscope. For these cases, the symptoms during metastasis and changes in electrocardiogram were studied clinically;
