Background and Objective: This study was conducted to investigate some clinical aspects of coronaryartery patients, as it included some tests for lipid oxidation and DNA damage and the extent of theirassociation with the risk of coronary artery disease in the Iraqi population. Results: The lipid showedsignificant differences between the preferred messages in measuring lipids, TG (P = 0.005), highdensitylipoprotein P = 0.018 (HDL) and low-density lipoprotein (vLDL) P = 0.004. It was named inlipid profile, and it was named In seizure patients (nonSTEMI). The glutathione analysis showed asignificant decrease in patients compared to healthy subjects, and the unstable, non-Stemi and Stemiseriesresults were significant, and the significant differences were at (P = 0.00036). As for the researchresults, the significant differences were when they were high (P = 0.00072). The results of the cometassay showed differences between the four groups, for the group of patients with unstable angina andwho suffer from a heart attack (Non-Stemi), the results showed close to average levels in the geneticmaterial (P = 0.00014). The highest damage in the genetic material of patients with coronary arterydisease was in patients suffering from a heart attack (Stemi) where the level of significant damage wasvery large compared to the rest of the groups (P = 0.00025). The results obtained on the biochemicallevels of GHs, VLDL, HDL, TG and MDA showed significant differences between the healthy and thegroups of patients with coronary artery disease below the probability level (P> 0.05). Also, the incidenceof DNA damage in patients with coronary artery disease is much greater than healthy patients, and thisindicates a significant effect of DNA damage on blood vessels, and on the other hand, STEMI patientsare the most vulnerable to infection.
