Study Overview

Brief Summary

Introduction: The coronary artery dilatations disease (Coronary artery aneurysm/coronary artery ectasia) characterized by inappropriate coronary artery dilations. (c.894G>T) is a gene polymorphism that may decreases eNOS enzyme activity which increases the risk for coronary heart disease by affecting released (NO) molecules. One of the most researched variations in eNOS gene is c.894G>T polymorphism, which changes amino acid sequence at position 298 from Glu (GAG) to Asp (GAT), nevertheless, its role in Coronary dilatations disease still uncertain.

Aim of study: To study correlation between the c.894G>T gene polymorphism and angiographically dilated coronary artery (CAA/CAE), as well as to determine whether there is any association between this polymorphism and atherosclerotic CAD.

Methodology: A comparative study on 100 patients with acute coronary syndrome who underwent coronary angiography from December 2020 to June 2022. According to standard angiographic views and expert opinions, patients were divided as, 25 patients normal, 25 patients had only atherosclerotic coronary artery disease, 25 patients had dilated coronaries (CAA/CAE) without atherosclerosis and 25 patients had dilated coronaries with atherosclerotic coronary artery disease. The specific genetic PCR laboratory test were performed for eNOS SNPs (single nucleotide polymorphism) namely, 894G > T (Glu298Asp; rs 1799983), using Real-Time PCR.

Detailed Description

Aim of Work We aim at determining the potential correlations between polymorphism of nitric oxide gene (c.894G>T) and angiographically dilated coronary arteries (coronary artery aneurysm or ectasia), as well as to determine if there is any link to atherosclerotic coronary diseases (ACAD).

Methodology:

Based on standard coronary angiographic views, two experienced independent operators evaluated the presence of coronary artery dilatations (CAA, CAE) and associated atherosclerotic CAD in all patients' angiograms.

Inclusion criteria Patients who have angiographically coronary artery dilatations (coronary artery aneurysm or ectasia) (CAA/CAE) with or without angiographic evidence of atherosclerotic CAD.

Another group of patients with angiographically normal or atherosclerotic coronaries without evidence of dilatation.
