Abstract: Objective To explore the relationship between angiotensin converting enzyme (ACE) (I/D) gene polymorphism and the level of high-sensitivity C-reactive protein (hsCRP) in type 2 diabetic patients with atherosclerosis treated with ramipril. Methods A total of 118 in type 2 diabetic patients with atherosclerosis aged 35 years or older without clinical proteinuria, heart failure, or low ejection fraction (<40%), who were not taking ACE inhibitors or (ARB), were randomized into two groups to receive treatment with ramipril (ACEI group, beginning with 2.5 mg/d till reaching 5 mg/d) or placebo for 3 months. The 99 patients in ACEI group were further divided into 3 subgroups according to ACE (I/D) genotypes DD, ID and II, each group consisting of at least 20 patients. The level of hsCRP was detected by enzyme-linked immunosorbent assay before and after the therapy. Result and Conclusion After therapy, hsCRP level significantly decreased, but hsCRP levels showed no significant differences between the groups of different ACE genotypes.
