Our findings correlate with those of several prior studies, in which AGT polymorphisms were associated with susceptibility to higher plasma angiotensin levels.[31,32] Jia et al (2014) reported a significant association between rs5051 and AGT levels in Chinese CAD patients.[28] However, several studies have reported conflicting results, with no significant association observed between rs699 and CAD.[33,34] Our findings indicate that the A/A genotype of rs5051 and the CC genotype of rs699 were significantly correlated with CAD. Here, AGT is linked to coronary artery disorder.
