E-selectin is associated with stable angina and myocardial infarction in a sample of Kurdish population

Area of Science:

• Cardiovascular Genetics
• Molecular Biology
• Immunology

Background:

• Endothelial dysfunction is a primary driver of Coronary Artery Disease (CAD).
• Leukocyte adhesion to the endothelium is an early marker of arteriosclerosis, regulated by selectins.
• E-selectin gene polymorphisms have been associated with ischemic heart disease (IHD).

Purpose of the Study:

• To investigate the association between E-selectin gene polymorphisms and ischemic heart disease (IHD).
• To determine the functional impact of the E-selectin gene polymorphism 7170G>C in Iraqi patients with IHD.
• To analyze the relationship between this polymorphism and different clinical outcomes of cardiovascular disease.

Main Methods:

• Study involved 200 Iraqi patients and controls from Erbil City.
• Participants were categorized into stable angina pectoris (SAP), myocardial infarction (MI), and healthy control groups.
• Sanger sequencing was used to analyze the E-selectin gene polymorphism 7170G>C.

Main Results:

• The E-selectin 7170G>C polymorphism was significantly associated with stable angina (SAP) and myocardial infarction (MI).
• Genotype CC was found more frequently in SAP patients compared to MI and control groups (p<0.05).
• The C allele was more prevalent in SAP patients (15.7%) than in MI (14.58%) and control (10.8%) groups.

Conclusions:

• Genetic variations in the E-selectin gene, specifically the 7170G>C polymorphism, significantly influence cardiovascular disease outcomes.
• The 7170G>C polymorphism may serve as a potential genetic marker for stable angina.
• Further research is warranted to elucidate the precise mechanisms linking E-selectin gene variations to cardiovascular disease pathogenesis.
