: Inflammation and procedural complexity are individually associated with adverse outcomes after percutaneous coronary intervention (PCI). We aimed to evaluate the association of high sensitivity C-reactive protein (hsCRP) with adverse events according to PCI complexity. We included patients with available hsCRP levels who underwent PCI at our center from 2012 to 2017. We compared patients with hsCRP ≥3 versus <3 mg/L. Complex PCI was defined as having ≥1 of the following: ≥3 different target vessels, ≥3 lesions treated, ≥3 stents implanted, bifurcation lesion treated with 2 stents, chronic total occlusion as target lesion, or total stent length >60 mm. The primary end point was major adverse cardiac events (MACEs) (composite of all-cause death, myocardial infarction, or target vessel revascularization) at 1 year. A total of 11,979 patients were included, of which 2,840 (24%) underwent complex PCI. In those, 767 (27%) had hsCRP ≥3 mg/L. The 1-year incidence of MACE was 6% (noncomplex PCI, low hsCRP), 10% (noncomplex PCI, high hsCRP), 10% (complex PCI, low hsCRP), and 15% (complex PCI, high hsCRP). Overall, hsCRP ≥3 mg/L was associated with an increased risk of MACE compared with hsCRP <3 mg/L; this was independent of the number of complex PCI features: 0 (adjusted hazard ratio [HR] 1.53; 95% confidence interval [CI] 1.27 to 1.86), 1 (adjusted HR 1.77; 95% CI 1.21 to 2.60), or ≥2 (adjusted HR 1.21; 95% CI 0.80 to 1.83) (pinteraction = 0.42). In conclusion, in patients who underwent PCI, elevated hsCRP is associated with an increased risk of ischemic events. The effect of elevated hsCRP on cardiovascular risk is consistent regardless of PCI complexity.

Abstract

: Inflammation and procedural complexity are individually associated with adverse outcomes after percutaneous coronary intervention (PCI). We aimed to evaluate the association of high sensitivity C-reactive protein (hsCRP) with adverse events according to PCI complexity. We included patients with available hsCRP levels who underwent PCI at our center from 2012 to 2017. We compared patients with hsCRP ≥3 versus <3 mg/L. Complex PCI was defined as having ≥1 of the following: ≥3 different target vessels, ≥3 lesions treated, ≥3 stents implanted, bifurcation lesion treated with 2 stents, chronic total occlusion as target lesion, or total stent length >60 mm. The primary end point was major adverse cardiac events (MACEs) (composite of all-cause death, myocardial infarction, or target vessel revascularization) at 1 year. A total of 11,979 patients were included, of which 2,840 (24%) underwent complex PCI. In those, 767 (27%) had hsCRP ≥3 mg/L. The 1-year incidence of MACE was 6% (noncomplex PCI, low hsCRP), 10% (noncomplex PCI, high hsCRP), 10% (complex PCI, low hsCRP), and 15% (complex PCI, high hsCRP). Overall, hsCRP ≥3 mg/L was associated with an increased risk of MACE compared with hsCRP <3 mg/L; this was independent of the number of complex PCI features: 0 (adjusted hazard ratio [HR] 1.53; 95% confidence interval [CI] 1.27 to 1.86), 1 (adjusted HR 1.77; 95% CI 1.21 to 2.60), or ≥2 (adjusted HR 1.21; 95% CI 0.80 to 1.83) (pinteraction = 0.42). In conclusion, in patients who underwent PCI, elevated hsCRP is associated with an increased risk of ischemic events. The effect of elevated hsCRP on cardiovascular risk is consistent regardless of PCI complexity.
