Abstract

Background: Atherosclerosis is a risk factor for cardiovascular disease. Smoking exacerbates atherosclerosis. In this study, we measured the cardio-ankle vascular index as an indicator of the severity of atherosclerosis, and the secondary derivative of photoplethysmogram (SDPTG) was used to determine changes in blood vessel stiffness after a period of smoking cessation.
Methods: The subjects were 84 male smokers who had participated in a ”non-smoking camp” at Daegu Medical Center from September to December 2015. Physical and biochemical examinations and a questionnaire identified risk factors for atherosclerosis. After 2 and 4 days of smoking cessation, changes in the SDPTG values in the entire group and in 3 groups divided according to the degree of vascular stiffness were analyzed by paired t-tests.
Results: After 4 days of smoking cessation, the differential pulse wave index (DPI) increased in the borderline group (P=0.030), the stress power (SP) increased in the entire, normal, and borderline groups (P=0.000, P=0.000, P=0.034), blood vessel tension (BVT) decreased in the normal group (P=0.022), and remained blood volume (RBV) decreased in the all groups (P=0.000, P=0.002, P=0.001, P=0.039 ).
Conclusion: SDPTG testing after short-term smoking cessation can be an objective indicator of changes in blood vessel stiffness, and can be helpful in motivating smokers to quit.
