  Purpose

Primary Objective

  • The main objective of this study is to assess if a two-month regimen of irbesartan in patients hospitalized for acute coronary syndrome without ST segment elevation can reduce inflammation markers (ie hsCRP), in comparison to a similar regimen of enalapril.

Secondary Objectives

  • To compare both regimens on several other biological parameters which have demonstrated their relevance and their predictive clinical value (ie BNP, microalbuminuria, troponin I …) in this patient population.
  • To compare on the above parameters the early initiation of treatment versus the initiation of treatment at hospital discharge.

Primary Outcome Measures:
  • comparison of the relative change from baseline in hsCRP at day 60 between the two treatment groups

Secondary Outcome Measures:
  • Relative change from baseline of hsCRP at discharge
  • Changes from baseline in BNP and Microalbuminuria (MAU) at discharge and day 60
  • Change of Troponin I from baseline at discharge
  • In addition at baseline, discharge and D60 the following parameters will be evaluated and their evolution compared in the two treatment groups: IL6, CD 40 L, sPLA2 and Lp-PLA2, IMA, MMP-9, MPO (myeloperoxydase), aldosterone
  • Blood pressure at discharge, D15 and D60.
  • The early versus late (at hospital discharge) initiation of treatment will also be evaluated on the above-listed parameters.
  • & Safety outcomes

Criteria

The following information on clinical trials is provided for information purposes only to allow patients and physicians to have an initial discussion about the trial. This information is not intended to be complete information about the trial, to contain all considerations that may be relevant to potential participation in the trial, or to replace the advice of a personal physician or health professional.

Main criteria are listed hereafter:

Inclusion Criteria
