Update: Professor Carl Phillips has published a blog post pointing out that this was a small study which examined only one aspect of the effect of e-cigaretts on the heart. He argues that while the results are positive, this does not show that e-cigarettes do not damage the heart any more than the recent airways study passage shows that e-cigarettes damage the lungs.
Update 2: Dr Farsalinos kindly agreed to an interview with the Ashtray Blog, which was carried out on our behalf by researcher Paul Bergen. Click here to read!
Electronic cigarettes cause no risk to the heart according to a new study presented at a European Society of Cardioligy conference.
The study, conducted by Dr Konstantinos Farsalinos, compared the effect of using electronic cigarette on the heart to that of cigarettes.
The study found that e-cigarettes:
- had no acute effects on cardiac function
- only had a very slight effect on blood pressure and heart rate
- that although nicotine was present in e-liquid, it is absorbed at a slower rate than in cigarettes
Speaking at the conference, Dr Konstantinos Farsalinos also pointed out that a vaper (e-cigarette user) would have to use an e-cigarette for 4-12 months to get the same amount of nitrosamines found in just one cigarette.
The study followed recent revelations that e-cigarettes have no negative effect on the blood count of passive or active users (see here and here for a summary of the studies.)
The scientist concluded:
It [the e-cigarette] is the only available product that deals with both the chemical (nicotine delivery) and psychological (inhaling and exhaling ‘smoke’, holding it, etc) addiction to smoking, laboratory analyses indicate that it is significantly less toxic and our study has shown no significant defects in cardiac function after acute use.
