Hazard ratios for recurrent AF after catheter ablation according to CRP cut-off value of 3 mg/l
| Variable | CRP level, mg/l | |
|---|---|---|
| < 3a | ≥ 3 | |
| Events/Patients | 181/551 | 66/160 |
| Incidence, %b | 36.9 | 53.8 |
| 95% CI | 31.6–43.2 | 41.6–69.6 |
| Hazard ratio unadjusted | 1.0 | 1.45 |
| 95% CI | – | 1.09–1.92 |
| P value | – | 0.010 |
| Hazard ratio adjusted for age and sex | 1.0 | 1.41 |
| 95% CI | – | 1.06–1.88 |
| P value | – | 0.017 |
| Hazard ratio adjusted for age and sex + additional factors | 1.0 | 1.44 |
| 95% CI | – | 1.06–1.95 |
| P value | – | 0.019 |
Models adjusted for additional factors controlled for body mass index, AF type (paroxysmal vs. persistent), history of hypertension (yes vs. no), history of heart failure (yes vs. no), history of obstructive sleep apnea (yes vs. no), duration of AF (years), and LAD
Multivariable model included n = 659 patients
aCRP group < 3 mg/l served as reference for each comparison
