Influence of cigarette smoking on coronary artery and aortic calcium among random samples from populations of middle-age Japanese and Korean men

摘要

BackgroundCigarette smoking is a risk factor of coronary heart disease (CHD). Vascular calcification such as coronary artery calcium (CAC) and aortic calcium (AC) is associated with CHD. We hypothesized that cigarette smoking is associated with coronary artery and aortic calcifications in Japanese and Koreans with high smoking prevalence.
