Vaping, E-Cigarettes, and Cardiovascular Health Risks
Acute Cardiovascular Effects of Vaping: Heart Rate and Blood Pressure
Research consistently shows that vaping e-cigarettes can cause immediate increases in heart rate and blood pressure, similar to the effects seen with traditional cigarette smoking. These acute changes are observed in both young adults and the general population, indicating that vaping is not free from short-term cardiovascular impacts Kundu2025Shahin2022. While the heart rate increase after vaping is generally lower than after smoking a cigarette, both activities raise blood pressure to a similar extent Kundu2025Shahin2022.
Vaping and Endothelial Dysfunction
Multiple studies highlight that vaping leads to oxidative stress and inflammation, which can damage the endothelium—the inner lining of blood vessels. This endothelial dysfunction is a key early step in the development of cardiovascular disease. The toxic compounds in e-cigarette vapor, such as reactive aldehydes, are believed to play a central role in this process, and the pathomechanisms overlap significantly with those caused by traditional cigarette smoke Verhaegen2019Daiber2023Kuntić2020.
Long-Term Cardiovascular Risks and Clinical Events
Although long-term data are still limited, evidence suggests that vaping is associated with an increased risk of adverse cardiovascular events, including arrhythmias, atrial fibrillation, and even myocardial infarction. Case reports have documented sudden cardiac arrest and various arrhythmias in individuals who vape, including young people Peruzzi2020Nagy2025Rose2023. However, the overall magnitude of risk appears to be lower than that associated with traditional cigarette smoking Peruzzi2020Shahandeh2021Kuntić2020.
Vaping Compared to Traditional Cigarettes
Most studies agree that while vaping may be less harmful than smoking traditional cigarettes, it is not harmless. Both products impair vascular function and increase cardiovascular risk, but the risk is generally lower with e-cigarettes than with combustible tobacco. Some evidence suggests that switching from cigarettes to e-cigarettes may improve certain cardiovascular measures, such as blood flow and blood pressure, especially in younger individuals and females Peruzzi2020Kundu2025Daiber2023+2 MORE.
Special Considerations: Youth and Non-Smokers
The popularity of vaping among adolescents and young adults is a growing concern. Many users are non-smokers who may be exposed to cardiovascular risks they would not otherwise face. The long-term effects in this group are not well understood, and more research is needed to assess the potential for vaping to serve as a gateway to traditional smoking and its associated risks Verhaegen2019Nagy2025Rose2023.
Gaps in Evidence and Need for Further Research
Despite the growing body of evidence, there is still a lack of long-term studies on the cardiovascular effects of vaping, especially in people who have never smoked traditional cigarettes. More research is needed to clarify the risks, understand the mechanisms involved, and inform public health policies Verhaegen2019Kundu2025Echeagaray2022+1 MORE.
Conclusion
Vaping is not a harmless alternative to smoking. It causes acute increases in heart rate and blood pressure, contributes to endothelial dysfunction, and is linked to adverse cardiovascular events. While the risks are generally lower than those of traditional cigarettes, vaping still poses significant cardiovascular health concerns, especially for youth and non-smokers. Ongoing research and stronger regulation are needed to fully understand and address these risks.
