ABSTRACT
Introduction
E-cigarettes have emerged as a popular alternative to traditional tobacco smoking in recent years. Despite their growing popularity, concerns have arisen regarding the cardiovascular implications of e-cigarette use.
Areas covered
This narrative review aims to highlight the latest evidence on the impact of e-cigarettes on cardiovascular health.
Expert opinion
Numerous studies have demonstrated that e-cigarette use can lead to acute adverse cardiovascular effects. Inhalation of e-cigarette aerosols exposes users to a wide range of potentially harmful substances that have been implicated in critical pathophysiologic pathways of cardiovascular disease, namely endothelial dysfunction, oxidative stress, inflammation, sympathetic overdrive, and arterial stiffness. While long-term epidemiological studies specifically focusing on the cardiovascular effects of e-cigarettes are still relatively scarce, early evidence suggests a potential association between e-cigarette use and an increased risk of adverse cardiovascular events. However, it is essential to recognize that e-cigarettes are relatively new products, and the full extent of their long-term cardiovascular impact has not been fully elucidated. In the meantime, promoting tobacco cessation strategies that are evidence-based and regulated, along with rigorous monitoring of e-cigarette use patterns and associated health outcomes, are essential steps in safeguarding cardiovascular health in the face of this emerging public health challenge.
Article highlights
E-cigarettes have emerged as a popular alternative to traditional tobacco smoking in recent years.
Inhalation of e-cigarette aerosols exposes users to a wide range of potentially harmful substances that have been implicated in cardiovascular disease pathophysiology.
The main pathways involved in e-cigarette induced cardiovascular toxicity are inflammation, oxidative stress, endothelial dysfunction, sympathetic overdrive, and stimulation of a prothrombotic state.
Observational studies suggest an association of e-cigarette smoking with cardiovascular outcomes.
E-cigarette smoking cannot be considered harmless toward cardiovascular health.
The public should be aware of the potential cardiovascular risks associated with their use and utilize evidence-based approaches to smoking cessation.
