© 2025 by the authors.Background: Diabetic patients tend to have complex coronary artery disease (CAD). Understanding their procedural risk may help to guide treatment strategies. SYNTAX and the British Cardiovascular Intervention Society Jeopardy Score (BCIS-JS) have been used to define complex CAD, but their use has not been compared in diabetic patients. Methods: This is a retrospective analysis of prospectively collected data of consecutive patients who underwent complex percutaneous coronary intervention (PCI) and were deemed unsuitable for surgical revascularization. Both SYNTAX and BCIS-JS were calculated by experienced operators who were blinded to patient’s outcome. The primary endpoint was all-cause mortality at 12 months. Results: Of 452 patients included in the study, diabetes was present in 35% patients. There was a modest relationship between BCIS-JS and SYNTAX score (Spearman r = 0.44, p < 0.001) and this relationship was even weaker in patients with diabetes (Spearman r = 0.32, p < 0.001). The primary endpoint was comparable in the non-diabetic group, irrespective of the score system (SYNTAX or BCIS-JS) used to define complex CAD. In contrast, there was a differential prognostic outcome in the diabetic group, whereby the primary endpoint was more frequently reported in diabetic patients with high versus low SYNTAX scores [HR 4.96, 95% CI (1.44–17.03), p = 0.011] but not when BCIS-JS was used. Conclusions: There was a modest relationship between BCIS-JS and SYNTAX score. Unlike BCIS-JS, the SYNTAX score identified those who are at increased risk of death among diabetic patients. Both scoring systems did not effectively differentiate mortality risk in non-diabetic patients. Future research is needed to confirm this study’s findings.
