Blood Endothelium Biomarkers to Predict Major Adverse Cardiovascular Events After Percutaneous Coronary Intervention

Assistance Publique Hopitaux De Marseille170 enrolled

Overview

In stent restenosis and myocardial infarction are have been linked the balance between injury and healing of the endothelium These processes can be measured respectively using the number of circulating endothelial cells and endothelial progenitor cells. We therefore aimed to evaluate the relationship between the balance of injury and healing of the endothelium at the time of PCI and major adverse cardiovascular events including death, myocardial infarction and target lesion revascularization at 6 and 12 months follow-up.

Following percutaneous coronary intervention with bare metal stents, the rate of major adverse cardiovascular events including death, myocardial infarction and target lesion revascularization is high ranging between 20 and 25%.

Data private hospitals, angioplasty, sampling of bloodOTHER

* Data private hospitals : Age, sex, index of body mass, factors of cardiovascular risk, medical surgical histories, treatment before and after the angioplasty, the renal insufficiency * coronary angioplasty * Sampling of blood : Before the angioplasty, 6 hours after the angioplasty and 24 hours after the angioplasty. A numeration of the proparents circulants (hématopoietics, PEC) and a numeration of CEC are made

Outcomes

Primary Outcomes

The main objective of this study is to estimate if the measure of CEC and PEC possesses a meaning forecast towards the arisen of complications post procedure.

Time frame: 36 months

Secondary Outcomes

To determine the relation between these endothelial biomarkers and the other usual parameters forecast complications post-angioplasty
