[Significance of atherosclerotic risk factors in the development of preatherosclerotic changes in the human aorta].

A study of the effect of the main risk factors of atherosclerosis in coronary patients on the prevalence of lipoidosis and prelipid changes in the aortal intima showed a week interrelationship between the studied risk factors and prevalence of lipoidosis. A noticeable significant interrelationship of the prevalence of prelipid changes in the aortal intima, patient's age, the IRI level and alpha-XC concentration in the blood plasma was established. An equation was described. A nomogram was presented permitting determination of the prevalence of prelipid changes in the aortal intima and, consequently, the phase of a course of atherosclerosis during the patient's lifetime on the basis of the above risk factors.
