Methods of multidimensional mathematical statistics were used for the combination of a set of simultaneous characteristics (risk factors) related to the development of ischemic heart disease into a single representative value as an index of the individual state. Successive values of this index give the time dependent changes of the individual state of health. Considering that these changes in time can be modelled linearly a classification criterion can be obtained taking also into account the evolution of the individual state of health.
采用多维数理统计方法，将与缺血性心脏病发生相关的一组同时存在的特征（风险因素）组合成一个单一的代表值，作为个体状态的指标。该指标的连续值给出了个体健康状态随时间的变化。考虑到这些随时间的变化可以用线性模型表示，还可以结合个体健康状态的演变情况得出一个分类标准。
