Objective: Cardiovascular diseases (CVD); defines a group including stroke, peripheral vascular diseases and coronary artery diseases. Ankylosing spondylitis (AS) patients have an increased risk for CVD. Mor tality rates of AS patients are 1.5 times that of the general population. Car diovascular events are responsible for 20-40% of mortality in these patients. Various tools and methods are being researched to detect and reduce this risk. In this study; in order to be a basis for researches, it was aimed to de termine the CVD risk factors knowledge levels of AS patients. Material and Methods: A total of 101 consecutive patients with AS, aged 18-60 years, who met the Assessment in Spondyloarthritis International Society classification criteria, were included in the study from the patients who ap plied to Atatürk University Rheumatology outpatient clinic. Demographic data and clinical characteristics of the participants were recorded. Quality of life was determined by the Assesment in Spondyloarthritis International So ciety. CVD risk factors knowledge levels were evaluated with the Cardio vascular Diseases Risk Factors Knowledge Level (CARRIF-KL) Scale. Results: The median value of the participants’ CARRIF-KL Scale score was calculated as 18.0 (minimum-maximum: 2-26). CARRIF-KL scores; it was found to be higher in the group over the age of 35, those with a disease duration of more than 10 years, those with additional disease, those with CVD, and those who exercise occasionally. No correlation or difference was found between other parameters. Conclusion: Although the CVD risk level of AS patients is higher than the general population, the CVD knowledge level of this patient group is not as high as expected. In this study, the ne cessity of CVD information programs for AS patients was revealed.
