Implication

Randomized trial measures urinary nicotine and cotinine to verify smoking history in infarction clinic attendees, indicating reliability of results.

Key Points

This research aims to assess the reliability of nicotine and cotinine levels in verifying smoking history among patients attending an infarction clinic.
Measuring urinary concentrations of nicotine and cotinine in volunteers with known smoking habits.
Comparing nicotine and cotinine levels before and after smoking cessation among subjects.
Assessing the accuracy of patient-reported smoking status based on urinary biomarkers.
In non-smokers, nicotine and cotinine levels were below detection limits, while smokers had always detectable levels.
Cotinine remained in urine up to 36 hours post-smoking, longer than nicotine.
46-53% of patients who reported stopping smoking had verified urinary biomarkers indicating cessation, compared to 63% self-reported rates.
