ABSTRACT
AIM:
Recent prospective studies have identified distinct plasma ceramides as strong predictors of major adverse cardiovascular events in patients with established or suspected coronary artery disease (CAD). Currently, it is uncertain whether higher levels of distinct plasma ceramides are associated with greater angiographic severity of coronary-artery stenoses in this patient population.METHODS:
We measured six previously identified high-risk plasma ceramide species [Cer(d181/160), Cer(d181/180), Cer(d181/200), Cer(d181/220), Cer(d181/240) and Cer(d181/241)] in 167 consecutive patients with established or suspected CAD, who underwent urgent or elective coronary angiography.RESULTS:
Approximately 77% of patients had a significant stenosis (≥50%) in one or more of the main coronary arteries, the majority of whom (â¼60%) had a significant stenosis in the left anterior descending (LAD) artery. Of the six measured plasma ceramides, higher levels of plasma Cer(d181/200) (adjusted-odds ratio 1.39, 95%CI 1.0-1.99), Cer(d181/220) (adjusted-odds ratio 1.57, 95%CI 1.08-2.29) and Cer(d181/240) (adjusted-odds ratio 1.59, 95%CI 1.08-2.32) were significantly associated with the presence of LAD stenosis≥50%, after adjustment for age, sex, smoking, pre-existing CAD, hypertension, diabetes, dyslipidaemia, lipid-lowering therapy, estimated glomerular filtration rate and plasma C-reactive protein levels. Almost identical results were found even after excluding patients (n=15) with acute ST-elevation myocardial infarction. Similar results were also found when patients were categorized according to the Gensini severity score.CONCLUSION:
Our cross-sectional study shows for the first time that higher levels of specific plasma ceramides are independently associated with a greater severity of coronary-artery stenoses in the LAD artery in patients who had suspected or established CAD.Palavras-chave
