Implication

Self-reported smoking underestimates exposure in coronary patients; leaves open whether routine cotinine verification improves outcomes or trial validity.

Structured PICO

Is self-reported smoking reduction accurate compared to biochemical cotinine levels in patients with diagnosed coronary heart disease?

P
Population
9740 Scottish men and women aged 40-59 years, including 625 with diagnosed coronary heart disease, 1497 undiagnosed but with suggestive symptoms/ECG signs, and 7618 with no diagnosis or evidence of coronary disease.
O
Outcome
Self-reported smoking habits compared to biochemical measures of tobacco smoke inhalation (cotinine)surrogate

Self-reported smoking habits in patients with diagnosed coronary heart disease are often distorted, highlighting the need for objective biochemical measures like cotinine to assess true tobacco intake.
