Gpr. Archbold et al., MEASUREMENT OF MARKERS OF TOBACCO SMOKING IN PATIENTS WITH CORONARY HEART-DISEASE, Annals of clinical biochemistry, 32, 1995, pp. 201-207
591 patients with a history of coronary heart disease had one or more
biochemical markers of tobacco smoking measured. 26% were self reporte
d smokers and a further 4% were apparent 'smoking deceivers'. The urin
ary nicotine metabolite concentration is an excellent marker for tobac
co smoking; breath CO would be a suitable alternative for busy clinics
. Half the patients were subjected to regular advice on risk factor ma
nagement but there was no evidence that this contributed effectively t
o smoking cessation. Overall smoking cessation rate was poor.
