Abstract:

Objective To study the individualized application of statin metabolism-related genomics in patients with cardiovascular and cerebrovascular diseases,and to investigate its role in blood lipid management. Methods A total of 141 patients with cardiovascular and cerebrovascular diseases(72 cases of coronary heart disease and 69 cases of cerebral infarction) were enrolled,and 70 healthy subjects were enrolled as healthy control group. Serum apolipoprotein A(apo A),apolipoprotein B(apo B),apolipoprotein E(apo E),lipoprotein(a)[Lp(a)],total cholesterol(TC),triglyceride(TG),low-density lipoprotein cholesterol(LDL-C),high-density lipoprotein cholesterol (HDL-C),free fatty acid(FFA) and the statin gene ABCB1(2677G>T),ABCB1(3435C>T)and SLCO1B1*5(T>C)single nucleotide polymorphisms(SNP) were determined. Results Serum TG,HDL-C,apo A,Lp(a) and FFA levels in cardiovascular and cerebrovascular disease group had statistical significance compared with healthy control group(P<0.05). Serum TG,HDL-C,LDL-C,apo A,Lp(a) and FFA levels in coronary heart disease group had statistical significance compared with healthy control group(P<0.05). Serum TG,HDL-C and Lp(a) levels in cerebral infarction group had statistical significance compared with healthy control group(P<0.05). Other blood lipid indicators had no statistical significance(P>0.05). The genotypes and frequency distributions of cardiovascular and cerebrovascular disease group,cerebral infarction group and coronary heart disease group had consistency. ABCB1(2677G>T) G allele frequency was higher than T allele frequency,ABCB1(3435C>T) C allele frequency was higher than T allele frequency,and SLCO1B1*5(T>C) T allele frequency was higher than C allele frequency. After the treatment with statins,serum TG,TC and LDL-C levels were lower than those before treatment(P<0.05),and serum HDL-C level was higher than that before treatment(P<0.05). There was statistical significance in the efficiency of statins in patients with different genotypes(P<0.05). Conclusions There are abnormal blood lipid levels in patients with cardiovascular and cerebrovascular diseases,and there is obvious individual difference for gene polymorphisms in patients with same disease. Pharmacogenomics detection in patients with cardiovascular and cerebrovascular diseases plays a role in guiding the clinical blood lipid-lowering treatment with statins.
