# Progress in the Application of the Residual SYNTAX Score and Its Derived Scores

## TL;DR

This paper reviews how the residual SYNTAX score and related metrics are used to assess and guide treatment for complex coronary artery disease.

## Contribution

The paper provides an updated review of clinical progress in using residual SYNTAX scores and their derived metrics for coronary disease evaluation.

## Key findings

- rSS is used to quantify residual coronary lesions and guide revascularization decisions.
- Combining rSS with other indicators improves prognosis evaluation in coronary disease.
- rSS-derived scores are increasingly applied in clinical practice for complex coronary artery cases.

## Abstract

The residual SYNTAX score (rSS) is employed for the quantification of residual
coronary lesions and to guide revascularization. rSS can be combined with other
examinations to evaluate the severity of vascular disease and play an evaluative
and guiding role in various scenarios. Furthermore, combining rSS with other
indicators, benefits prognosis evaluation, and rSS-derived scores have been
increasingly used in clinical practice. This article reviews the progress in the
clinical application of rSS and its derived scores for complex coronary arteries
and other aspects, based on relevant literature.
