Onary heart disease .Recently, the protein asymmetric dimethylarginine (ADMA), an endogenous eNOS inhibitor, has garnered interest as a prospective biomarker for endothelial dysfunction .Plasma levels of ADMA are negatively correlated with NO levels and are elevated in a assortment of illnesses traditionally associated with cardiovascular risk, such as hypertension, dyslipidemia, diabetes mellitus andInt.J.Mol.Scichronic kidney illness .Elevated plasma ADMA has also been related with enhanced danger of cardiovascular events across a array of patient populations .Many other molecules, like inflammatory cytokines, regulators of thrombosis and indicators of endothelial harm and repair have already been proposed as biomarkers for endothelial dysfunction .The clinical significance of most of these prospective biomarkers remains unclear, nevertheless..Clinical Findings of Major Chronic Inflammatory Diseases Suggest Cardiovascular Risk Rheumatoid arthritis, systemic lupus erythematosus, the seronegative spondyloarthropathies, psoriasis and inflammatory bowel disease have all been linked clinically with excessive cardiovascular risk .Over the last numerous decades, there has been considerable interest in characterizing this excess cardiovascular threat in an try to determine possible risk factors and mechanisms accountable for the genesis of atherosclerosis in these populations (Table).Table .Relative threat of cardiovascular morbidity and mortality.Disease Rheumatoid Arthritis Systemic Lupus Erythematosus Psoriasis (severe) Ankylosing Spondylitis Inflammatory Bowel Illness CAD Risk (RR or OR) . . . . .
