Multifaceted analysis of the interactions of morphophysiologic signs and ischemic ECG changes (a population study)

: Relationships between serum lipid and lipoprotein levels, arterial blood pressure, body weight and age, on the one hand, and coronary heart disease (CHD), on the other, were investigated by means of the main constituents analysis in a Northern Khant population. The pattern of relationship between the parameters in question was similar, by the first main constituent, in males and females, and suggested their age-dependence, unrelated to CHD. The second constituent, as a sum total of the effects of another factor, showed an unbalance between body weight and blood lipids, which was correlated with CHD in males and remained indifferent with respect to CHD in females.
