Methods Sequence specific primers-polymerase chain reaction was used for the detection of genotypes and alleles of rs3850641 A/G loci in OX40L gene in 187 PACS cases (≤55 years) and 138 controls. Diseased vessel numbers and stenostic severity integral by coronary arteriogram and serum levels of sOX40L, C-reactive protein and vascular cell adhesion molecule-1 (VCAM-1) by enzyme-linked immunosorbent assay and nephelometry were measured. The relationship between OX4OL gene variants and PACS risk, SSI as well as plasma levels of three cytokines were analysed.
