Preoperative systemic immune inflammation index predicts early complications and 30-day mortality after heart valve surgery: a retrospective cohort study.

ABSTRACT:

Background

The systemic immune-inflammation index (SII) is considered a promising inflammatory index for predicting adverse outcomes in cardiovascular diseases. However, its prognostic value in patients undergoing heart valve surgery remains unclear. This study aimed to investigate the predictive significance of preoperative SII for early postoperative complications and 30-day mortality.

Methods

This was a retrospective, single-center cohort study conducted at the National Cardiovascular Center Harapan Kita in Jakarta, Indonesia, a tertiary cardiac surgery referral hospital. It included adults (> 18 years) who underwent elective aortic, mitral, or combined valve surgery between January 2020 and December 2024. After applying exclusion criteria, 1347 patients were stratified b
