Study Reveals that Electronic Cigarette Doesn’t Impair Cardiac Function


Electronic cigarettes were invented in China in 2003, and since then they are sold all over the world and have been used by millions of people around the world.

This kind of cigarettes has the advantage of not having thousands of other chemicals as the traditional cigarettes. So, smokers all over the world are replacing the normal cigarettes for electronic cigarettes.

Smoking normal cigarettes is the most preventable risk factor for heart and lung diseases, and is expected to cause 1 billion deaths during the 21st century. Wouldn’t be great if this kind of numbers could diminish? According to a 2012 Greek study, in contrast to these normal cigarettes, the electronic cigarettes have no adverse effects on cardiac function. So, it is possible to reduce the number of this deaths. Konstantinos Farsalinos, a doctor that is one of the researchers at the Onassis Cardiac Surgery Center in Athens, reveals that although electronic cigarettes aren’t a totally healthy habit and its long-term effects need to be studied, they are a safer alternative to conventional cigarettes. He also said, at the annual congress of the European Society of Cardiology in Munich, that “Given the extreme risks associated with smoking cigarettes, the data currently available suggests that electronic cigarettes are much less harmful, and replacing tobacco with electronic cigarettes can be beneficial to health.”.

40% of deaths in smokers are due to coronary artery disease. Since heart disease is the leading cause of morbidity and mortality in smokers, this Greek research team decided to perform the first clinical study of the acute effects of electronic cigarettes on cardiac function. They also have decided to compare their results with the acute effects of normal cigarettes on cardiac function since electronic cigarettes are considered to be an alternative healthier habit. Therefore, in this Greek study, was observed the cardiac function of 20 young smokers, before and after smoking normal tobacco. The cardiac function of 22 electronic cigarettes was observed too, to compare the data between the 2 differences.  This cardiac function was examined using cardiac ultrasound (echocardiography) and hemodynamic measurements (blood pressure and heart rate). And the results were that those who used exclusively the electronic cigarettes only had a slight increase in blood pressure while the tobacco smokers had a significant cardiac dysfunction.

According to Reuters, this was the first clinical study designed worldwide, focused on the cardiac effects of electronic cigarettes. Another Greek study, presented earlier, also concluded that electronic cigarettes have little impact on lung function.

This study just proves what the general population already thinks about the electronic cigarettes: electronic cigarettes are a much healthier option than normal tobacco. But is great to have scientific proves that confirm this fact, instead of being based in common sense.

So, if your family has a medical history of cardiac diseases and you smoke normal tobacco, you should really considerer changing to electronic cigarettes. But even if your family doesn’t have this kind of medical history electronic cigarettes are a better option that should be considered.
