Abstract

Current smoking is the strongest predictor of future morbidity and mortality in those with cardiovascular disease, yet clinically, smoking status is usually ascertained through self-report. We objectively measured smoking status, using exhaled carbon monoxide (CO), for 1122 consecutive patients entering cardiac rehabilitation. Within those with elevated CO levels (≥4 ppm), females had CO levels almost twice that of males (20.4 vs. 11.6), suggesting higher amounts of smoking.
