[Microelement concentration in the blood plasma, erythrocytes and hair of patients with coronary disease with risk factors]. / Soderzhanie mikroélementov v plazme krovi, éritrotsitakh i volosakh bol'nykh IBS s faktorami riska.

The effect of risk factors contributing to coronary heart disease (CHD) on the trace element levels in the blood plasma, blood red cells and hair was studied in 250 CHD patients and in the control group. CHD without risk factors was associated with significantly higher plasma levels of zinc, manganese and copper, while copper concentrations in the hair were significantly lower than in control. The positive correlation between the manganese content in the red cells and hair in the control group was not true for the CHD patients. Manganese levels were found to be directly correlated with low density lipoproteins and inversely correlated with high density lipoproteins. Plasma zinc levels and erythrocyte calcium concentrations in CHD patients with risk factors were significantly lower than in CHD patients without risk factors.
