Prognostic Implications of Preoperative hs-cTnT in Elective Coronary Artery Bypass Grafting.

ABSTRACT:

Background

Elevated preoperative hs-cTnT may reflect underlying myocardial vulnerability, potentially influencing surgical timing and perioperative strategies in patients undergoing elective coronary artery bypass grafting (CABG).

Objectives

This study investigates the association between preoperative hs-cTnT levels, perioperative outcomes, and long-term mortality, aiming to improve risk stratification and guide clinical decision-making.

Methods

This retrospective study analyzed a consecutive series of 5,450 patients undergoing CABG at 2 tertiary centers between 2010 and 2023. Patients were categorized into 3 groups based on preoperative hs-cTnT levels: 1) nonelevated (<1x upper reference limit [URL]); 2) mildly elevated (1-3x URL); and 3) significantly elevated (>3x
