Kinetics of C-Reactive Protein During the Management of Acute Coronary Syndrome Treated by Transluminal Angioplasty

Recruiting

• Conditions: Acute Coronary Syndrome

• Registration Number: NCT05233176
• Lead Sponsor: Assistance Publique - Hôpitaux de Paris

Brief Summary

The primary objective of the study focuses on the kinetics of plasma CRP measured during the overall management (before the angioplasty procedure until the discharge of hospitalization) of patients with ST+ ACS requiring emergency transluminal angioplasty.

Detailed Description

During the management of acute coronary syndrome with ST segment elevation (ACS-ST+), an ischemia-reperfusion syndrome is observed in connection with primary coronary occlusion (ischemia) and percutaneous angioplasty during the therapeutic coronary reperfusion.

This ischemia-reperfusion syndrome results biologically in an inflammatory syndrome evaluated in particular by the assay of C-reactive protein (CRP). CRP is a marker of inflammation used in routine practice. Previous studies have reported the prognostic value of CRP at the 48th hour of hospital treatment for ST+ ACS. If the value of CRP is correlated with the risk of mortality and heart failure, the fact remains that no study has, to date, studied its kinetics during the overall management (pre and intra-hospital) of ACS ST+. This is all the more important since the previous therapies taken by the patient (statins for example) and/or those administered during treatment (colchicine, ticagrelor, anti-GPIIbIIIa are capable of modifying the pre-hospital value of the CRP.

In this study, the kinetics of plasma CRP measured during the first medical contact (emergency, cardiology or resuscitation), then, in the catheterization room before the angioplasty procedure, then in the catheterization room, after the angioplasty, then at the 6th hour (H6), at the 12th hour (H12), at the 24th hour (H24), at the 48th hour (H48) and once a week until the 7th day then once a week until discharge hospitalization with a maximum of 30 days of follow-up, as part of the usual follow-up of patients with ST+ ACS requiring emergency transluminal angioplasty.
