The constituents of the fat of 136 decedents who had died of ischaemic heart disease are compared with the constituents of the fat from 95 controls who had died from other causes. The cases had a lower concentration of fatty acids (L) characteristic of ruminant animal fat and a higher concentration of total transunsaturated acids (T), but the concentrations of certain higher (C20 and C22 mostly monoenoic) acids (H) were similar. The ratio T/L was higher in the cases, which suggests that the cases may have consumed more hydrogenated fats in life than had the controls. The ratio T/L increased linearly with H within both the case and control specimens, which suggests in view of the similarity in the mean levels of H that the difference in trans contents may be concentrated in the lower (18:1 and 16:1) trans acids.
将136例死于缺血性心脏病的死者的脂肪成分与95例死于其他原因的对照者的脂肪成分进行比较。病例组中反刍动物脂肪特有的脂肪酸（L）浓度较低，总反式不饱和酸（T）浓度较高，但某些高级（主要是C20和C22单烯酸）酸（H）的浓度相似。病例组的T/L比值较高，这表明病例组在生活中可能比对照组摄入了更多的氢化脂肪。在病例组和对照组样本中，T/L比值均随H呈线性增加，鉴于H的平均水平相似，这表明反式含量的差异可能集中在较低的（18:1和16:1）反式酸中。
