RESUMO
BACKGROUND: Data on the prognostic value of high-sensitivity C-reactive protein (hs-CRP) levels in patients with chronic kidney disease (CKD) undergoing percutaneous coronary intervention (PCI) are limited. METHODS: Patients undergoing PCI at a tertiary center from January 2012 to December 2019 were included. CKD was defined as a glomerular filtration rate (GFR) <60â¯mL/min/1.73m2 and elevated hs-CRP was defined as >3â¯mg/L. Acute myocardial infarction (MI), acute heart failure, neoplastic disease, patients undergoing hemodialysis, or hs-CRP >10â¯mg/L were exclusion criteria. The primary outcome was major adverse cardiac events (MACE), a composite of all-cause death, MI, and target vessel revascularization at 1-year after PCI. RESULTS: Out of 12,410 patients, 3029 (24.4â¯%) had CKD. Elevated hs-CRP levels were found in 31.8â¯% of CKD and 25.8â¯% of no-CKD patients. At 1â¯year, MACE occurred in 87 (11.0â¯%) CKD patients with elevated hs-CRP and 163 (9.5â¯%) with low hs-CRP (adj. HR 1.26, 95â¯% CI 0.94-1.68); among no-CKD patients, in 200 (10â¯%) and 470 (8.1â¯%), respectively (adj. HR 1.21, 95â¯% CI 1.00-1.45). Hs-CRP was associated with an increased risk of all-cause death in both CKD (Adj. HR 1.92, 95â¯% CI 1.07-3.44) and no-CKD patients (adj. HR 3.02, 95â¯% CI 1.74-5.22). There was no interaction between hs-CRP and CKD status. CONCLUSIONS: Among patients undergoing PCI without acute MI, elevated hs-CRP values were not associated with a higher risk of MACE at 1â¯year, but with increased mortality hazards consistently in patients with or without CKD.
