Correlation between platelet-derived growth factor-B gene polymorphism and coronary heart disease

Area of Science:

• Cardiovascular Research
• Molecular Biology
• Genetics

Background:

• Coronary heart disease (CHD) poses a significant global health challenge.
• Platelet-derived growth factor (PDGF) plays a role in cardiovascular pathophysiology.
• Understanding genetic predispositions and molecular markers is crucial for CHD management.

Purpose of the Study:

• To investigate the association between plasma PDGF-BB levels and PDGF-B gene single nucleotide polymorphisms (SNPs) with CHD onset and stability.
• To determine if specific PDGF-B SNPs (rs1800817 and rs2285094) correlate with CHD.
• To explore the relationship between plasma PDGF-BB and indicators of inflammation in CHD patients.

Main Methods:

• A cohort of 335 subjects underwent coronary angiography and were categorized into CHD (n=247) and control (n=88) groups.
• CHD patients were further classified into acute coronary syndrome (ACS) and stable angina pectoris (SAP) groups.
• Plasma PDGF-BB levels were quantified using ELISA, and PDGF-B gene genotypes were analyzed via qPCR.

Main Results:

• Plasma PDGF-BB levels showed a positive correlation with high-sensitivity C-reactive protein (hsCRP) levels (r=0.149, p<0.05).
• No significant association was found between PDGF-B gene SNPs (rs1800817 and rs2285094) and CHD.
• Elevated plasma PDGF-BB levels were identified as an independent risk factor for CHD onset (OR=1.003, p=0.014).

Conclusions:

• Elevated plasma PDGF-BB levels are a risk factor for coronary heart disease (CHD) onset and are associated with CHD instability.
• Plasma PDGF-BB level variations may be linked to inflammatory responses within the cardiovascular system.
• The studied polymorphisms in the PDGF-B gene (rs1800817 and rs2285094) do not appear to be correlated with the development of CHD.
