Abstract:
BACKGROUND:Percutaneous coronary intervention (PCI) with bare metal stent (BMS) deployment causes plaque disruption and a rise in systemic levels of C-reactive protein (CRP), interleukin (IL)-6, and monocyte chemoattractant protein (MCP)-1. Our aim is to study whether PCI with sirolimus-eluting stent (SES) use attenuates this response. METHODS:Patients with stable angina undergoing single-vessel PCI were enrolled in a randomized, open-label fashion into a BMS group or an SES group. Blood samples were drawn pre-PCI, 24 hours post-PCI, and 30 days post-PCI. Systemic concentrations of CRP, IL-6, and MCP-1 were measured at all time points. RESULTS:In total, 41 patients were enrolled (21 in the BMS group and 20 in the SES group). The baseline plasma concentrations of all markers were comparable between groups. At 24 hours, the mean plasma CRP concentration in the SES group was 20.21 mg/dL versus 8.95 mg/dL in the BMS group (P = 0.15). The mean plasma IL-6 concentration at 24 hours was 25.41 pg/mL in the SES group versus 17.44 pg/mL in the BMS group (P = 0.17). The mean plasma MCP-1 concentration at 24 hours was 382.38 pg/mL in the SES group versus 329.04 pg/mL in the BMS group (P = 0.2). At 30 days, plasma concentrations of all three markers decreased to similar values between groups. CONCLUSIONS:The use of SES did not inhibit the rise in systemic concentrations of CRP, IL-6, and MCP-1 at 24 hours or 30 days post-PCI, compared with BMS. Moreover, at 24 hours, there was a trend for higher systemic levels of all proinflammatory markers in the SES group compared with the BMS cohort.
