The severity of coronary artery lesions was evaluated using the SYNTAX scoring system. Linear regression analyses were performed to assess the differences in SYNTAX scores among different mean-HbA1c groups, as well as SD-HbA1c and CV-HbA1c quartiles.</p><p><strong>Results: </strong>A total of 115 diabetic patients were included in the study. The mean-HbA1c cutoff value of 7.5 was derived from the receiver-operating characteristic curve. Fifty-six patients had a mean-HbA1c of 7.5 or lower, whereas 59 patients had a mean-HbA1c above 7.5. Univariate analysis revealed that patients with mean-HbA1c above 7.5 had significantly higher SYNTAX scores compared to those with lower mean-HbA1c levels (12.79 vs. 7.33, <i>P</i> < 0.05). There was no significant correlation observed between SD-HbA1c, CV-HbA1c, and SYNTAX scores in both univariate and multivariate analyses.</p><p><strong>Conclusion: </strong>This study suggests that higher mean-HbA1c levels are associated with increased severity of CAD in individuals with T2DM. However, long-term HbA1c variability, as measured by SD-HbA1c and CV-HbA1c, does not appear to have a significant impact on the severity of CAD.</p>","PeriodicalId":50062,"journal":{"name":"Journal of Research in Medical Sciences","volume":"30 ","pages":"47"},"PeriodicalIF":1.5,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12536863/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145349606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
