Abstract:
Objective To observe the association between adiponectin and small dense low-density lipoprotein (sLDL-c) in coronary artery disease (CAD) patients.Furthermore,we sought to determine the association between single nucleotide polymorphisms (SNP) rs1501299 ( + 276G/T ), rs266729 (-11365C/G) and the incidence of CAD.Methods Consecutive subjects with chest discomfort were examined by coronary angiography and divided into non-CAD [ n =250,147 male,mean age (60.26 ±7.52) years] and CAD [n =267,153 male,mean age (60.79 ±9.63) years] groups.Blood samples were collected from all participants following an overnight fasting for at least 12 hours.Plasma adiponectin levels were measured by competitive enzyme-linked immunosorbent assay (ELISA).The serum levels of sLDL-C and oxidized low-density lipoprotein (ox-LDL) were determined by ELISA.Genotypes in rs1501299 and rs266729 of the adiponeetin were determined by polymerase chain reaetion ( PCR ).Results 1.The adiponectin levels were significantly lower [ ( 306.17 ± 74.52 ) mg/L vs.( 321.78 ± 86.28 ) mg/L ],whereas sLDL-C and ox-LDL levels were significantly higher [ ( 276.30 ± 45.55 ) ng/L vs.( 249.00 ±32.02) ng/L and (545.06 ± 115.46 ) μg/L vs.(497.74 ± 106.09 ) μg/L,P < 0.05 ] in CAD group than non-CAD group.2.Adiponectin level was negatively associated with sLDL-C,whereas sLDL-C positively correlated with ox-LDL in all subjects.3.Genotype distribution and allele frequencies of rs1501299 and rs266729 were similar between CAD and non-CAD subjects and not related to the serum levels of adiponectin, sLDL-C and ox-LDL.Conclusions Reduced adiponectin and increased sLDL-C were independent risk factors for coronary artery disease.Genetic polymorphisms in rs1501299 and rs266729 were not linked with coronary artery disease.
