Abstract
The present study was designed to evaluate the role of some inflammation [interleukin (IL)-1beta, soluble IL-1 receptor, IL-1 receptor antagonist (IL-1RA), high-sensitivity C-reactive protein (hsCRP) and fibrinogen], and remodeling markers [matrix metalloproteinase (MMP)-9, tissue inhibitor of metalloproteinase (TIMP)-1 and TIMP-2] in patients with acute coronary syndrome (ACS; 40 patients), or chronic stable angina (CSA; 40 patients) compared to age- and sex-matched healthy controls (20 subjects). IL-1RA, hsCRP, fibrinogen, MMP-9, and TIMP-1 plasma levels were significantly higher in patients than in controls, whereas soluble IL-1 receptor had an opposite pattern. Among patients with ACS, hsCRP plasma levels were higher in patients with non-ST segment elevation myocardial infarction (NSTEMI) than in those with unstable angina (UA). TIMP-1 plasma levels were higher in those patients with ACS who did not respond to medical therapy (non-responsive unstable angina; NR-UA). A CRP plasma level higher than 0.86 mg/dl had a 91% positive predictive value (PPV) and 63% negative predictive value for NSTEMI (odds ratio = 6.4, 95% confidence interval = 1.5-27.4). TIMP-1 plasma level higher than 21.5 ng/ml had a 100% PPV for patients with NR-UA or NSTEMI. Binary logistic analysis confirmed TIMP-1 levels as being able to predict responsiveness to therapy. In conclusion, a different biochemical pattern characterizes ACS patients: those with NR-UA show only an increase of remodeling markers, whereas ACS patients with NSTEMI have an increase of both remodeling and inflammation markers.
