(Reuters) – Greek researchers took to the labs to find out what effect if any electronic cigarettes have on the users heart. Tobacco based cigarettes have been long since known to cause significant cardiac dysfunctions such as increases in heart rate as well as high blood pressure. This study took a comparative look at two small groups. The first group was examined after smoking a single tobacco cigarette, while the second group was examined after using an electronic cigarette for seven minutes.
The electronic cigarette liquid had a nicotine content of 11mg/ml and the electronic cigarette users were all experienced “vapers”.
Dr Konstantinos Farsalinos, lead author of this clinical study, announced the finding to in ESC Congress’s Aug 2012 meeting. Farsalino’s studies reveal that while smoking just one tobacco cigarette has significant and immediate effects producing cardiac dysfunction, those using the electronic cigarette did not experience those effects. This result seems important because these very effects that the tobacco smoker experienced (and the electronic cigarette user did not) are usually the first sort of defects in heart function seen before any clinically evident heart diseased develops.
Farsalinos describes: “It is too early to say whether the electronic cigarette is a revolution in tobacco harm reduction but the potential is there. It 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.”
Well this seems to be a step in the right direction Farsalinos also cautioned that these results were based on short term studies and that over time long term studies will develop a broader picture:
