Assessment of serum levels of asymmetric dimethylarginine, symmetric dimethylarginine and l-arginine in coronary artery disease

Abstract

Serum asymmetric dimethylarginine (ADMA), symmetric dimethylarginine (SDMA), l-arginine, and C-reactive protein (hsCRP) levels were assessed in 100 Egyptian male 35-50-year-old patients with coronary artery disease (CAD), classified into: patients under conservative medical treatment, patients directed for percutaneous coronary interventions, patients directed for coronary artery bypass graft operation and patients suffering from acute myocardial infarction. Age- and sex-matched controls (n-100) were included. Correlation between serum levels of biomarkers and dimethylarginine dimethylaminohydrolase-2 (DDAH-2) genotypes was studied. No association between biomarkers and carriage of the specific DDAH2 SNP2 (-449C/G, rs805305) genotype was detected. Further studies are required to confirm the contribution of the biomarkers in the predisposition of CAD. © 2010 Informa UK, Ltd.
