Smoking after heart transplantation: An underestimated hazard?

Abstract

Our data show that the prevalence of smoking after heart transplantation may be relatively high, especially in former smokers. Repeated measurements of CO-Hb could be helpful in its detection. Despite a relatively low cigarette count, smoking is a major risk factor of morbidity and mortality after heart transplantation (HTx). Approximately 4 years of exposure time is needed to uncover its negative influence. These findings should lead to aggressive smoking screening and weaning programs in every HTx center.
