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.

Single Nucleotide Polymorphisms-SNPs01:05

Single Nucleotide Polymorphisms-SNPs

A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Coronary Artery Disease I: Introduction

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...

Pharmacogenetic Phenotypes: Alterations in Pharmacokinetics, Drug Targets and Biologic Milieu

Genetic variations significantly influence drug response through pharmacokinetics, receptor interactions, and biologic milieu modifications. Pharmacokinetic alterations impact drug metabolism and clearance, affecting efficacy and toxicity. Variants in drug-metabolizing enzymes, such as CYP2C9 and CYP2C19, alter drug activation and elimination. For example, CYP2C9 loss-of-function variants require lower warfarin doses to prevent excessive bleeding, while CYP2C19 variants reduce clopidogrel...

Coronary Artery Disease IV: Preventive Measures

Effective preventive measures for coronary artery disease (CAD) focus on controlling modifiable risk factors, including cholesterol abnormalities and lifestyle changes.Cholesterol ManagementFirst, the Mediterranean diet and the American Heart Association advocate for maintaining low-density lipoprotein (LDL) cholesterol levels below 100 mg/dL, with a more stringent recommendation of below 70 mg/dL for individuals at high risk. LDL cholesterol, often termed "bad cholesterol," can lead to the...
Coronary Artery Disease II: Pathophysiology01:26

Coronary Artery Disease II: Pathophysiology

Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...
