BACKGROUND: In non-ST-segment elevation acute coronary syndromes (NSTE-ACS), the relation of the level of high-sensitivity C-reactive protein (CRP) to the progression of atherosclerosis remains unclear. METHODS AND RESULTS: The study group comprised 153 patients with NSTE-ACS who underwent percutaneous coronary interventions (PCI) and follow-up (mean interval, 7 months) coronary angiography. Rapid progression was defined as > or =10% diameter reduction of a preexisting stenosis > or =50%, > or =30% diameter reduction of a stenosis <50%, development of a new stenosis > or =30% in a previously normal segment, or progression of any stenosis to total occlusion. Progressors had higher CRP levels on admission and at 48 h after PCI, a higher level of low-density lipoprotein cholesterol at follow-up, a higher rate of multiple complex lesions, and a lower frequency of statin use at follow-up than nonprogressors. Multivariate analysis showed that admission CRP elevation (CRP level on admission > or =0.166 mg/dl, median value; odds ratio (OR) 2.92, p=0.010), post-PCI CRP elevation (CRP level 48 h after PCI > or =1.586 mg/dl, median value; OR 2.67, p=0.022), and multiple complex lesions (OR 2.66, p=0.017) were independent predictors of rapid progression of nonculprit lesions. CONCLUSIONS: Enhanced inflammatory response to PCI, as well as baseline inflammatory activity as reflected by CRP level, may be involved in the progression of atherosclerosis in NSTE-ACS.
