Markers of Vascular Aging and Coronary Syndrome

Not Applicable

Completed

• Conditions: Acute Coronary Syndrome
• Interventions: Biological: blood sample withdrawn

• Registration Number: NCT02857387
• Lead Sponsor: CHU de Reims

Brief Summary

Atherosclerosis and aging are associated to the raise of biochemical alterations of proteins grouped under the name of " non-enzymatic post-translational modifications ". They often correspond to the irreversible binding of glucose or other oses (glycation) or urea derivatives (carbamylation) on proteins and lead to the formation of complex compounds (post-translational modifications derived products, PTMD) that can accumulate in tissues and be responsible for deleterious effects. The specific role of these compounds in the pathophysiology of aging and atherosclerosis remains unknown, as are the molecular and cellular mechanisms implicated.

This project is based on the hypothesis that non-enzymatic post-translational modifications may cause changes in the genesis of complication of coronary atherosclerosis and that PTMD could therefore constitute relevant biomarkers in this specific clinical situation.

To explore these potential new biomarkers, the investigators designed a study in patients having experienced an acute coronary syndrome and followed during a year. The concentrations of PTMD assayed at 0, 1, 3, 12 months, will be correlated to clinical (severity and evolution) and paraclinical (cutaneous autofluorescence) data and the effect of cardiac rehabilitation will be assessed.

This should help to identify new (and non-traditional) biomarkers of coronary heart disease and determine some of the implicated pathophysiological mechanisms.
