Methods: 78 (27 women, mean age 43.95 +/- 7.28) patients with CSF, and 70 (22 women, mean age 44.34 +/- 7.08) healthy individuals were included in the study. Arterial stiffness measurement was performed to both groups via CFPWV, which is considered the gold standard. Aortic elastic properties (ASI-beta and aortic distensibility) were evaluated in both groups. Results: The CSF group had significantly higher CFPWV and aortic distensibility values and significantly lower ASI-beta values compared to the control group. There was a positive correlation between TIMI frame count (TFC) obtained in all coronary arteries and CFPWV and aortic distensibility, and a negative correlation between TFC and ASI-beta. It was determined that CFPWV predicted CSF with 97% specificity and 98% sensitivity at a 7.68 cut-off value (ROC area = 994, p < 0.001). ASI-beta was determined to predict CSF with 64% specificity and 47% sensitivity at a 2.98 cut-off value (ROC area = 047, p < 0.001). Aortic distensibility was determined to predict CSF with 76% specificity and 79% sensitivity at a 3.94 cut-off value (ROC area = 706, p < 0.001). Conclusion: Arterial stiffness increases in CSF patients, suggesting that CSF is a systemic pathology rather than a local disease and that a systemic cause such as atherosclerosis plays a role in etiology.eninfo:eu-repo/semantics/openAccessCoronary slow flowarterial stiffnesscarotid-femoral pulse wave velocityaortic elastic propertiesArticle910.1177/204800402097309433240493WOS:000590926300001N/A
