Insights
Aging, hypertension, and lower antithrombin III (ATIII) levels are key risk factors for coronary heart disease (CHD) in elderly Chinese Han patients. Genetic variations in platelet glycoprotein, angiotensin-converting enzyme, and ATIII also contribute to CHD susceptibility.
Area of Science:
- Cardiovascular Medicine
- Genetics
- Geriatrics
Background:
- Coronary heart disease (CHD) poses a significant health challenge, particularly among aging populations.
- Identifying risk factors and genetic predispositions is crucial for effective prevention and management of CHD in the elderly Chinese Han demographic.
Purpose of the Study:
- To investigate the clinical risk factors associated with CHD in old Chinese Han patients.
- To explore the genetic susceptibility to CHD by examining specific single nucleotide polymorphisms (SNPs).
Main Methods:
- A case-control study involving 246 CHD patients and 185 controls.
- Logistic regression analysis was used to assess correlations between CHD and 15 risk factors.
- Genotyping of 11 SNPs across 10 genes was performed using high-throughput systems.
Main Results:
- Aging, hypertension, and lower antithrombin III (ATIII) levels were identified as significant risk factors for CHD (P < 0.05).
- Specific SNPs, including GP1BA rs2243093, ACE rs4332, and ATIII rs2227589, showed associations with CHD.
- Certain genotypes and alleles of these SNPs demonstrated significant odds ratios and confidence intervals for CHD risk.
Conclusions:
- Aging, hypertension, and diminished ATIII levels are primary risk factors for CHD in the studied population.
- The renin-angiotensin system, platelet function, and anti-coagulation pathways are implicated in the pathogenesis of CHD in elderly Chinese Han individuals.
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).
Conclusion:
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.
