Children exposed to tobacco smoke have worse heart function as adults

Conference
AHA 2020

Childhood passive smoke exposure, independent of whether the individuals smoke themselves, was associated with a reduction in global longitudinal strain (GLS), a measure of subclinical cardiac dysfunction [1]. The more passive smoke exposure a child had, the higher the risk for reduced heart function.

Although it is generally assumed that prolonged childhood exposure to passive smoke may affect adult cardiovascular (CV) health, there are few studies of cardiac function decades after the exposure. Subclinical left ventricular dysfunction detected by GLS is predictive of the subsequent development of heart failure and was used as a surrogate for increased risk. The investigators addressed the association of passive smoke exposure during childhood with GLS in adulthood.

Dr Chigozie Ezegbe (University of Tasmania, Australia) presented the data, derived from the Childhood Determinants of Adult Health Study 34-year follow-up (2014–2019). From a validated ...
