title: [Correlation of coronary heart disease with multiple genes, gene polymorphisms and multiple risk factors in old Chinese Han patients].
abstract: OBJECTIVE
  To explore the related risk factors and genetic susceptibility of coronary heart disease (CHD) in old Chinese Han patients.
  
  
  METHODS
  In a case-control study, we enrolled 246 patients with CHD for cases, 185 cases without CHD for control. Correlation of CHD with 15 risk factors, including sex, age, smoking, drinking, hypertension, diabetes mellitus, hyperlipidemia, homocysteine (HCY), N-terminal pro-brain natriuretic peptide (NT-pro-BNP), high-sensitivity C-reactive protein (Hs-CRP), antithrombin III (ATII), cholesterol (CHOL), triglycerides (TG), high density lipoprotein (HDL) and low density lipoprotein (LDL) were analyzed by a logistic regression analysis. Meanwhile, facilitated by USA Sequenom high-throughput single nucleotide polymorphisms (SNP) genotyping systems, 10-Plex Genes, 11 SNPs were investigated.
  
  
  RESULTS
  Aging, hypertension, lower ATIII were major risk factors for CHD (P < 0.05). Platelet glycoprotein GP1BA rs2243093 (-5T/C), angiotensin-converting enzyme ACE rs4332 (547C/T) and ATIII rs2227589 (893C/T) were associated with CHD in old Han Chinese patients. Mutant genotype CC of rs2243093 (-5T/C) compared with T + AT, P was 0.029 (OR = 3.41, CI: 1.19-9.75). Heterozygous TC of rs4332 (547C/T) was compared with CC + TT, P is 0.003 (OR = 0.56, CI: 0.38-0.82). T-allele carrier CT + CT of rs2227589 (893C/T) was compared with wild genotype CC, P = 0.003 (OR = 1.79, CI: 1.22-2.63).
  
  
  CONCLUSIONS
  Our study demonstrated that aging, hypertension, lower ATIII were the major risk factors of CHD. Three mechanisms associated with platelets, anti-coagulation system, the renin-angiotensin system were involved in coronary heart disease in the elderly.
