[Value of systematic biological markers of inflammation for the prognosis at 12 months of patients undergoing programmed coronary angioplasty].

Abstract

Value of systematic dosage of biological markers of inflammation for the prognosis at 12 months of patients undergoing programmed coronary angioplasty Systematic dosage of proteins of inflammation has been suggested for assessing the prognosis of athero-thrombotic diseases. The authors undertook a study of plasma C-reactive protein (CRP) and interleukin 6 (IL-6) for evaluating the prognosis of patients undergoing programmed coronary angioplasty. A prospective monocentric study of 117 patients (65 +/- 8 years) was divided into a control group of 28 patients undergoing coronary angiography (Group 1) and 89 patients undergoing programmed coronary angioplasty (Group 2). Serum IL-6 and CRP levels were measured before arterial puncture and at H12 and H24 after coronary catheterisation. The follow-up period was 12 months. The angioplasty did not significantly increase CRP and IL-6 concentrations compared with coronary angiography. Twenty patients (Group 2) (22%) suffered a cardiovascular event in the 12 months' follow-up. These patients had significantly higher CRP levels at H0, H12 and H24 after coronary angioplasty than those who had uncomplicated outcomes. This was not observed for IL-6 concentrations because of the wide dispersion of the results obtained. Increased CRP concentrations between H0 and H24 was also a good predictive factor independently of high basal CRP levels potentially due to other causes than atheroma. Coronary angioplasty is associated with increased CRP at H0, H12 and H24. These values are correlated with the risk of future events at 6 and 12 months. This information is easily obtained and should help management of these patients.
