Surgical ablation for atrial fibrillation: impact of Diabetes Mellitus type 2
An erratum to this article was published (Cardiovasc Diabetol, 18 May 2023 ↗)
Authors' conclusion
Surgical ablation had a high success rate, with freedom from recurrent atrial arrhythmia at 1- 3- and 5- years follow-up in both the DM type 2 and non-DM groups. Furthermore,1- and 3-year mortality after surgical ablation was also similar in both groups. However, 5-year mortality was higher in the DM type 2 group.

- Mortality · 5 years · higher with DM type 2
- P = 0.009
- Baseline/operative characteristics — DM patients older, more hypertension and cerebrovascular accident (CVA)/transient ischemic attack (TIA), higher EuroSCORE · longer bypass time with DM type 2
- P < 0.05 for all · P = 0.028
Mortality · 5 years
- 5-year mortality higher in DM type 2 vs non-DM
