    Objective To investigate relations between inflammation and aortic valve stenosis (AS) by measuring high-sensitivity C-reactive protein, at baseline (hsCRP0) and after 1 year (hsCRP1) and exploring associations with aortic valve replacement (AVR). Design We examined 1423 patients from the Simvastatin and Ezetimibe in Aortic Stenosis study. Results During first year of treatment, hsCRP was reduced both in patients later receiving AVR (2.3 [0.9–4.9] to 1.8 [0.8–5.4] mg/l, p < 0.001) and not receiving AVR (1.90 [0.90–4.10] to 1.3 [0.6–2.9] mg/l, p <0.001). In Cox-regression analyses, hsCRP1 predicted later AVR (HR = 1.17, p < 0.001) independently of hsCRP0 (HR = 0.96, p = 0.33), aortic valve area (AVA) and other risk factors. A higher rate of AVR was observed in the group with high hsCRP0 and an increase during the first year (AVRhighCRP0CRP1inc=47.3% versus AVRhighCRP0CRP1dec=27.5%, p < 0.01). The prognostic benefit of a 1-year reduction in hsCRP was larger in patients with high versus low hsCRP0 eliminating the difference in incidence of AVR between high versus low hsCRP0 (AVRhighCRP0CRP1dec=27.5% versus AVRlowCRP0CRP1dec=25.8%, p = 0.66) in patients with reduced hsCRP during the first year. Conclusions High hsCRP1 or an increase in hsCRP during the first year of follow-up predicted later AVR independently of AVA, age, gender and other risk factors, although no significant improvement in C-statistics was observed.
