Resumo
Standard lipoprotein measurements of triglycerides, total cholesterol, low-density lipoproteins (LDL), and high-density
lipoproteins (HDL) fail to identify many lipoprotein abnormalities that contribute to cardiovascular heart diseases (CHD).
Studies suggested that the presence of CHD is more strongly associated with the HDL subspecies than with total HDL
cholesterol levels. The HDL particles can be collected in at least three subfractions, the HDL2b, HDL2a, and HDL3. More
specifically, atherosclerosis is associated with low levels of HDL2. In this work, the optical spectroscopic properties of
europium tetracycline (EuTc) complex in the presence of different HDL subspecies was studied. The results show that the
europium spectroscopic properties in the EuTc complex are influenced by sizes and concentrations of subclasses. Eu3þ
emission intensity and lifetime can discriminate the subfractions HDL3 and HDL2b.
