The predictive value of the clinical residual SYNTAX score for clinical outcomes in elderly acute coronary syndrome patients with comorbidities undergoing PCI

The results of this study suggest that the CRSS could serve as a valuable prognostic marker, potentially providing clinical utility in evaluating the extent of revascularization for elderly ACS patients with comorbidities undergoing PCI. Compared with the RSS, the CRSS demonstrated significantly greater predictive performance for all-cause death and cardiac death within this cohort.
