Changes in ceramide concentrations and their association with clinical and anamnestic parameters in patients with acute coronary syndrome

Background. Given the metabolic dynamics of acute coronary syndrome (ACS), the study of molecular lipid metabolites is of particular importance because their composition most rapidly reflects the changes occurring at the time of the acute event. Several prospective studies have demonstrated the prognostic value of ceramides, however, the study of their dynamics and association with clinical parameters of patients with ACS is underrepresented. Objective. To investigate changes in Cer(d18:1/16:0), Cer(d18:1/18:0), Cer(d18:1/24:0), and Cer(d18:1/24:1) ceramide concentrations and their association with clinical and anamnestic parameters in patients with ACS. Design and methods. Lipidomic analysis by high-performance liquid chromatography tandem mass spectrometry was performed among 110 patients with ACS. Results. At admission to the hospital the ceramide level was the highest and decreased with time (for all p < 0.001). The peculiarities of ceramide concentrations depending on clinical and anamnestic parameters of patients with ACS are shown. Ceramides were found to be weakly correlated with age and high-sensitivity troponin I, and moderately correlated with lipid profile at different time periods. For the first time, information on Cer(d18:1/16:0) and Cer(d18:1/24:0) levels depending on disease debut, Cer(d18:1/16:0) concentration depending on duration of the pain attack, and Cer(d18:1/18:0) level depending on the presence of family history of cardiovascular disease is presented. Conclusion. The dynamics of ceramide concentrations over time and the peculiarities of their levels depending on the clinical and anamnestic parameters of patients with ACS expand the understanding of the importance of lipid metabolites.
