Abstract
Objective: Carotid intima-media thickness(IMT) is one of the useful marker for atherosclerosis and increased IMT predicts for cardio-vascular disease(CVD). Prevalence of atrial fibrillation(AF) is increasing with age, and the elderly have complications such as CVD and AF. We investigated whether IMT was related with prevalence of AF. Methods: We performed a health check-up in Tanushimaru in 2018. A total of 1368 subjects were measured IMT by using ultrasonography, and were examined electrocardiography and echocardiography. Results: Mean IMT was 0.72 ± 0.21 mm, 18 subjects (1.3%) had AF. The characteristics of age (p < 0.001), systolic blood pressure (p < 0.001), LDL-cholesterol (p = 0.0026), E/A ratio (p < 0.001), Left ventricular end-diastolic diameter (p = 0.0199), Left Atrial Dimension (p < 0.001) and prevalence of AF (p < 0.001) were significantly associated with the IMT quartiles. After adjustment for age and sex, the significances of factors were remained. Conclusion: This study demonstrated that increased IMT was associated with prevalence of AF. A prospective study is needed to examine whether increasing IMT predicts for incidence of AF.
