Damage to the endothelium is the earliest event in atherothrombosis, including AMI. Nitric oxide (NO), an endothelium-derived compound, protects the vasculature from damage. This study evaluated whether an association exists between plasma concentration of endogenous NO-related pathway metabolites linked to AMI and major adverse cardiovascular events (MACE) after AMI.Methods: We compared plasma concentrations of NO-related pathway metabolites in patients after AMI (n=60) and healthy controls (n=27) and investigated the prognostic value of these metabolites for post-AMI MACE development over a median of 3.5-years. In search of biomarkers, we compared plasma concentrations of dimethylarginines (ADMA, SDMA), citrulline, arginine and ornithine using ultra performance liquid chromatograph coupled with a mass spectrometer.Results: Patients after AMI had higher concentrations of dimethylarginines, compared to controls (p=0.0068, p< 0.0001, respectively). Conversely, the concentration of citrulline was lower in the AMI group (p=0.0006). The concentration of SDMA was higher in patients who developed MACE than in those who did not (p=0.015). SDMA was the only independent predictor of MACE in multivariate analysis (p=0.023). There was an intermediate, negative correlation between plasma SDMA level and platelet reactivity (r=− 0.33, p=0.02).Conclusion: Plasma concentration of dimethylarginines differs between patients with AMI and healthy volunteers. The study’s novel finding is that SDMA is an independent predictor of MACE during a 3.5 year follow-up period after AMI.Keywords: nitric oxide, L-arginine, acute myocardial infarction, major adverse cardiovascular events, prognosis |
