Cardiovascular impact of non-combustible nicotine products

Clinical data and international reviews have examined the impact of transitioning from traditional cigarettes to non-combustible nicotine products, such as heated tobacco systems and electronic cigarettes, on cardiovascular health.

Initial findings presented at the Hellenic Cardiological College highlighted a 12-month UK study where adult smokers switching to a tobacco heating system showed significant reductions in biomarkers of toxic substance exposure. These changes included improvements in indicators related to inflammation, oxidative stress, platelet activation, and endothelial function, with some results mirroring those seen in complete smoking cessation.

A subsequent international review published in ‘Advances in Clinical and Experimental Medicine’ synthesized data from multiple studies, including research from South Korea and the University of Dundee. The review noted reductions in carbon monoxide exposure and carcinogen metabolites, alongside improvements in arterial stiffness and vascular endothelial function. While these studies suggest that switching to non-combustible products may lower cardiovascular disease risk compared to continued smoking, researchers consistently emphasized that complete smoking cessation remains the most effective strategy for long-term health.
