Atrial fibrillation after lung cancer surgery: incidence, severity, and risk factors

Abstract

Purpose

Atrial fibrillation (Af) is a common post-operative cardiac complication after lung cancer surgery; however, the type of lung cancer surgery being performed has evolved, remarkably, into minimally invasive surgical procedures. The purpose of this study was to quantify the incidence and severity of post-operative Af and to identify the risk factors for Af, using a recent cohort of lung cancer surgery patients.

Methods

We reviewed, retrospectively, the medical records of 593 patients, who underwent lung cancer surgery between 2011 and 2013, for the development of post-operative Af.

Results

The overall incidence of post-operative Af in our study was 6.4 % (38/593). Three (8 %) of these 38 patients, subsequently, suffered brain infarction. Multivariate analysis revealed that mediastinal lymph node dissection (OR ND-2/ND-0–1 = 3.06; 95 % CI 1.06–10.9) was associated with the development of post-operative Af.

Conclusion

Omission of mediastinal lymph dissection for patients with early stage lung cancer and a high risk of Af should be considered to prevent post-operative Af.
