Endothelial lipase (EL) is a novel member of the triglyceride (TG) lipase family. A growing body of evidence has indicated that EL gene polymorphism might contribute to the process of cardiovascular diseases. This study was aimed to reveal the potential relationship between EL -384A/C gene polymorphism and acute coronary syndrome (ACS) in a Chinese Han population. The subjects were composed of 320 ACS patients and 315 age- and gender- matched controls. We detected the EL -384A/C genotypes and allele frequencies by using polymerase chain reaction-restriction fragment length polymorphism analysis. There was significant difference in AA genotype and AC+CC genotype between ACS and control groups (P = 0.014). The A allele frequency was significantly higher in ACS group than in control group (87.8 vs 83.8 %, P = 0.041). The relationship between the variant and ACS remained significant after adjusting for current smoker, hypertension, diabetes mellitus, total cholesterol and TG (OR = 0.682, 95 % CI = 0.472-0.986). The levels of HDL and ApoA-I were significantly higher in AC+CC genotype than in AA genotype (HDL: 1.20 ± 0.35 vs 1.11 ± 0.29 mmol/L, P = 0.001; ApoA-I: 1.14 ± 0.25 vs 1.08 ± 0.21 g/L, P = 0.009). We found that the EL -384A/C gene polymorphism might be associated with ACS in Chinese Han population, suggesting that the variant might be involved in the pathogenesis of ACS.
