Chronotropic incompetence could negatively influence post-operative risk assessment in patients before lung cancer surgery.

ABSTRACT:

Background

Cardiopulmonary exercise testing (CPET) is a standard part of preoperative evaluation in patients before lung surgical resection. According to current guidelines the risk of such a procedure is estimated according to maximum oxygen consumption (VO₂max). Chronotropic incompetence (CI) is a prevalent condition which could possibly influence cardiopulmonary fitness. The aim of this study was to assess the prevalence of CI in patients before surgical lung resections and its influence on CPET results.

Methods

This study enrolled 154 patients (97 men) of average age 66.4±8.3 with newly diagnosed lung cancer indicated for surgical lung resections. All patients underwent CPET (cycle ergometry). Age predicted maximal HR was calculated using the traditional equat
