AF patients were divided into two groups: the short-standing AF category (less than a year) and the long-standing AF category (more than a year). All patients had laboratory testing of 13C urea breath test, high-sensitive C-reactive protein (hs-CRP) and left atrial diameter (LAD). We analyzed the difference of these factors in all groups and explored the correlation between Hp infection and AF using logistic regression analysis.Results: Both AF groups had more hypertension, diabetes, and Hp infection than the control group. The Hp value and the hs-CRP level in patients with long-standing AF were higher than those in the short-standing AF and the control groups (for Hp value: P5 mg/L, and LAD >36 mm were significantly related to long-standing AF.Conclusion: The values of Hp in patients with long-standing AF were significantly higher than those in short-standing AF and control groups. Hp δ value ≥4‰ is an independent predictor for long-standing AF. Keywords: high sensitivity C-reactive protein, left atrial diameter,13C urea breath testA Letter to the Editor has been received and published for this article.
