    OBJECTIVE This study investigated the clinical significance of coronary artery tortuosity (CAT) in chronic coronary syndrome (CCS) by using Gensini scores. METHODS The retrospective single-center study involved 388 patients undergoing coronary angiography for chest pain, excluding those with acute coronary syndromes or prior coronary interventions. Demographic, clinical, and angiographic data were collected and categorized based on the presence or absence of CAT. Categorical variables were analyzed using appropriate statistical tests, with significance set at p < 0.05. RESULTS Analysis of 388 patients revealed that CAT was associated with older age (p <0.001), female gender (p <0.001), lower smoking (19.3% vs. 29.6%, p=0.025), and hypertension (53.5% vs. 38.7%, p=0.05). There was a slightly higher, nearly significant, prevalence of diabetes in the CAT group (22.8% vs. 14.5%, p=0.051). Furthermore, CAT correlated with diastolic dysfunction (p=0.04) and inversely with coronary atherosclerosis severity, as indicated by lower Gensini scores correlating with higher CAT scores (p=0.039 and p=0.049, respectively). Univariate analysis confirmed CAT's association with older age (p <0,001), female gender (p <0,001), hypertension (p=0,004), diabetes (p=0,039), diastolic dysfunction (p=0,003), and Gensini score (p=0,012). Multivariate analysis further identified significant correlations with age (p=0,001), female gender (p <0,001), and Gensini score (p=0,049). CONCLUSIONS Our findings indicate that older age and female gender predict CAT development in CCS patients. The lower Gensini scores associated with CAT may possibly be due to a reduced atherosclerotic plaque burden in these patients. Further research into this relationship could inform the development of treatment and management strategies for coronary atherosclerosis.

    Reply to the letter to the editor: 'Coronary atherosclerosis burden and coronary artery tortuosity'

    To the Editor, First, we would like to thank the author1 and the editorial team for their attention to and interest in our work. We deeply value your constructive criticism and contributions, which we see as an opportunity for further improvement. Collateral circulation plays a significant role in the prognosis of coronary artery disease.2 We acknowledge the importance of considering the effect of collateral circulation when calculating Gensini scores.3 In our retrospective study, while evaluating cases of chronic coronary syndrome that underwent coronary angiography, the coronary collateral flow assessment (Rentrop) score (3) was 0 in all cases. However, we accept that this detail should have been clarified more explicitly in our article. Our study aimed to minimize confounding factors as much as possible to realistically examine the relationship between coronary artery tortuosity and coronary atherosclerosis. While we acknowledged in the limitations section of our study that this might introduce a potential bias in patient selection,4 we accept that it would have been beneficial to explicitly state that we sought to eliminate the effect of collateral circulation. One of the key strengths of our study is the large patient cohort, along with the meticulous exclusion of other confounding factors. In conclusion, while recognizing the importance of collateral circulation, we believe that our study provides important information about the relationship between coronary artery tortuosity and atherosclerotic plaque burden. We hope this research contributes to a deeper understanding of coronary artery disease and offers a new perspective for future studies.
