Preoperative submaximal cardiopulmonary exercise testing and its association with early postoperative complications.

ABSTRACT:

Background

Early postoperative complication risk prediction would enhance perioperative surveillance and resource allocation. Reports have described brief submaximal cardiopulmonary exercise testing (CPET) for the routine assessment of cardiopulmonary disease. Compared with conventional CPET, it can be performed in 6 min and is used to predict peak CPET measurements. We aimed to determine whether submaximal CPET-derived measures outperform structured surveys in early postoperative complication detection.

Methods

An institutional review board-approved, single-centre, open-label, clinical device trial was conducted. A total of 101 participants undergoing noncardiac surgery, aged >60 yr, with revised cardiac risk index ≤2, self-reported metabolic equivalents >4 (METs in ml O
