The weights of hearts among 110 octogenarians were studied. At autopsy they ranged from 174 to 785 gm, which is more than the customary norm for adults. In only 15 subjects were the hearts considered completely normal. Other hearts showed hypertrophy, friable muscle, fatty infiltration, brown atrophy, a flabby myocardium, valvular changes, and atheroma or calcification of the coronary arteries. The frequency of these changes and their relationship to heart weight are discussed. A previous study of heart weights among 39 nonagenarians had shown weights ranging from 159 to 539 gm --- somewhat less than those among the octogenarians. Heavy heart weights are common in these two age groups.
对110名八旬老人的心脏重量进行了研究。尸检时，心脏重量在174克至785克之间，超过了成年人的常规标准。只有15名受试者的心脏被认为完全正常。其他心脏表现出肥大、心肌脆弱、脂肪浸润、褐色萎缩、心肌松弛、瓣膜改变以及冠状动脉粥样硬化或钙化。讨论了这些变化的频率及其与心脏重量的关系。先前对39名九旬老人心脏重量的研究表明，心脏重量在159克至539克之间——略低于八旬老人的心脏重量。心脏重量偏重在这两个年龄组中很常见。
