Smoking cessation improves vascular function by positively affecting endothelial and arterial stiffness markers, though evidence certainty ranges from moderate to very low.
Does smoking cessation or switching to e-cigarette use improve vascular function?
Smoking cessation improves vascular function markers, supporting the cardiovascular benefits of sustained abstinence.
Smoking cessation appears to improve vascular function, as reflected by early favorable changes in endothelial and arterial stiffness markers; however, the overall certainty varies from moderate to very low, according to the outcome. These findings are consistent with the biological plausibility of cardiovascular benefit from sustained smoking abstinence.
George et al. (2026) studied this question. Smoking cessation improves vascular function by positively affecting endothelial and arterial stiffness markers, though evidence certainty ranges from moderate to very low.
