Abstract

Diminished physical activity is a frequent phenomenon leading to a higher incidence of cardiovascular morbidity and mortality. Our study aimed to assess the impact of physical activity on arterial stiffness and inflammation. Classification of physical activity was performed in 1945 individuals of the cross-sectional "Corinthia" study using the International Physical Activity Questionnaire. Demographic and clinical characteristics were obtained via a standardized questionnaire. Arterial stiffness was estimated via carotid-femoral pulse wave velocity evaluation, and the inflammatory burden was assessed via high sensitivity C reactive protein (hsCRP) measurement. Participants with low physical activity had the most impaired carotid-femoral pulse wave velocity values while abnormally increased measurements-adjusted for age and blood pressure-were more frequently encountered in individuals with low physical activity. Participants characterized as having vigorous physical activity had the lowest inflammatory burden, as estimated by hsCRP levels. The results remained unaffected even after adjustment for confounders. In a subgroup analysis according to sex, increased arterial stiffness and inflammatory burden were noted similarly in female and male subjects within the lowest percentile of physical activity. In conclusion, a significant association between physical activity, arterial stiffness, and inflammation was observed, even after adjusting for known cardiovascular risk factors.
