Nicotine In E-Cigarettes Can Increase Risk Of Heart Attacks, Strokes: Study

According to a new study, E-cigarettes with nicotine content can make the arteries stiff, which in future can lead to increased risk of heart attacks and strokes.

Dr Magnus Lundback, who introduced the research at the European Respiratory Society International Congress, said, “The number of E-cigarette users has increased dramatically in the last few years. E-cigarettes are regarded by the general public as almost harmless. The E-cigarette industry markets their product as a way to reduce harm and to help people to stop smoking tobacco cigarettes.” On the other hand, the safety of E-cigarettes is also being talked about and growing evidences are suggesting several adverse health effects too.

“The results are preliminary, but in this study we found there was a significant increase in heart rate and blood pressure in the volunteers who were exposed to e-cigarettes containing nicotine. Arterial stiffness increased around three-fold in those who were exposed to nicotine containing E-cigarettes compared to the nicotine-free group,” Dr Lundback further added.

Dr Lundback along with his colleagues examined that after smoking E-cigarettes containing nicotine, there was a significant increase in the blood pressure, heart rate and arterial stiffness but, no such effect was seen on the volunteers who had smoked E-cigarettes without nicotine.

“It is very important that the results of this and other studies reach the general public and the health care professionals working in preventive health care, for example in smoking cessation. Our results underline the necessity of maintaining a critical and cautious attitude towards E-cigarettes, especially for health care professionals. E-cigarette users should be aware of the potential dangers of this product, so that they can decide whether to continue or quit based on scientific facts.”

He continued, “Therefore, our research concerns a very large population and our results may prevent future health problems for a huge number of people. It is of the utmost importance to investigate further the possible long-term effects of daily E-cigarette use through studies that are funded independently of the E-cigarette industry.”
