Since Japanese mortality associated with cardiovascular disease (CVD) is lower than that in the USA although Japan is one of the top four tobacco consuming countries, this study aims to determine biomarkers of both level of exposure and CVD-related biological effects in Japanese smokers compared to non-smokers.
Biomarkers of Exposure (BoExp) include 2-naphthylamine (2-NA), 4-aminobiphenyl (4-ABP), 4-(methylnitrosaminoi)-1-(3-pyridil)-1-butanone (NNK), carbon monoxide (CO), nicotine, pyrene and 0-toluidine (o-TOL). CVD-related biomarkers include white blood cell (WBC) count, high sensitivity C-reactive protein (hs-CRP) and homocysteine in plasma; complemented with urinary 8-epi-prostaglandin F2α (8-epi-PGF2α), plasma malondialdehyde (MDA), urinary 11-DTXB2, plasma fibrinogen, high-density lipoprotein-cholesterol, triglycerides, sICAM-1, sVCAM-1 and von Willebrand Factor.

- The level of biomarkers of Exposure (BoExp) to HPHCs - present in cigarette smoke - in Asian smokers compared to non smokers [ Time Frame: At Visit 2 (up to14 days after Visit 1) ]To measure the level of smoking, at baseline the Fagerstrom nicotine dependence test and urinary cotinine are measured. For measurement of biomarkers of exposure, blood and 24 hour urine sampling are performed at V2.
- The level of CVD-related biomarkers in Asian smokers compared to non smokers [ Time Frame: At Visit 2 (up to14 days after Visit 1) ]
