Abstract: | Positive coronary artery remodeling is associated with unstable coronary syndromes. Serum inflammatory markers, including high-sensitivity CRP (hsCRP), can predict future risk of acute coronary events in patients with stable coronary artery disease. We sought to elucidate the relationship of specific serum inflammatory markers with intravascular ultrasound (IVUS) estimation of coronary artery remodeling in patients with stable coronary artery disease. Thirty-one sequential patients at our institution undergoing IVUS-assisted percutaneous coronary intervention (PCI) with stable coronary artery disease were enrolled. Automated IVUS pullback and offline analysis were performed in all patients. Images were analyzed for vessel wall area (VWA) and lumen area (LA), at the culprit lesion and at a proximal reference site, and the remodeling index (RI) was calculated. Positive and negative remodeling were defined as a RI of > 1.05 and < 0.95, respectively. ELISA essays were performed for soluble VCAM-1, ICAM-1 and E-selectin. The distribution of data followed a lognormal distribution. By defining arterial remodeling as simply positive or negative, significant differences were identified for log E-selectin only (1.80 +/- 0.04 versus 1.62 +/- 0.05, respectively; p = 0.02). The RI correlation coefficient was 0.38 (p = 0.04) for log sVCAM-1 and 0.42 (p = 0.02) for log sICAM-1. The log E-selection and RI correlation coefficient, although weaker at 0.32, showed a trend toward significance (p = 0.08). There was no significant correlation between log hsCRP and RI (p = 0.42). Using step-wise multivariate analysis, log sVCAM-1 only remained an independent predictor of the RI (p = 0.03). Positive coronary artery remodeling correlates with serological markers of inflammation in patients with stable coronary artery disease. |
