Abstract
Aim: The index study aimed to investigate the clinical impact of initial high-sensitivity C-reactive protein (hs-CRP) on outcomes in nonvalvular atrial fibrillation (AF). Methods: Single-center, prospective, observational study recruiting all recently diagnosed treatment-naive AF patients. Hs-CRP was measured at baseline and patients were followed for 24 months. Results: A total of 126 patients with a mean age of 66.2 (±12.0) years were enrolled. The composite outcome of major adverse cardiac or cerebrovascular events (MACCE) occurred in 19 (17.7%) at 24 months. Raised initial hs-CRP emerged as an independent predictor of MACCE on regression analysis (OR: 1.569, 95% CI: 1.289–1.912; p < 0.001). Conclusion: Raised hs-CRP was an independent predictor of MACCE at 24 months. It allows for early identification of high-risk patients.
