From: Validation of EuroSCORE II in atrial fibrillation heart surgery patients from the KROK Registry
Kaplan–Meier 30-days (inner graphs—90-days) survival analysis in relation to perioperative risk and atrial fibrillation (AF). Patients are stratified to: (A) total population; (B) low-risk patients; (C) mild risk patients; (D) moderate risk patients; (E) high risk patients. Significant differences between occurrence of AF and survival are evident in all groups in 30-days follow-up (p < 0.001) and in patients with risk ≤ 5% in 90-days follow-up.
