Fun fact: A group of researchers from the University of Virginia Commonwealth have found that Viagra may be useful in treating prostate cancer when used in combination with doxorubicin. The combination of drugs has also been found useful in the treatment of ovarian and stomach cancer.

The use of electronic cigarettes does not cause immediate adverse effects on coronary circulation and the supply of oxygen to the heart, according to a new study presented on August 13, 2013 at the European Society of Cardiology at the annual congress in Amsterdam.

Researchers at the Onassis Cardiac Surgery Center, led by lead investigator Dr. Konstantinos Farsalinos, evaluated the effects of using electronic cigarettes on the maximal capacity of the coronary arteries to deliver blood and oxygen to the heart itself. They recruited 60 participants, 30 smokers and 30 users of electronic cigarettes. Measurement of maximal coronary blood flow was performed in smokers before and after smoking 2 cigarettes, and then, on a different day, after using an electronic cigarette with the concentration of nicotine 18mg/ml during 15 minutes. In electronic cigarette users, coronary circulation was evaluated before and after using the same electronic cigarette device for 15 minutes.

"This is the first study that has examined the effects of the use of electronic cigarettes in coronary circulation," said lead researcher Dr. Konstantinos Farsalinos. "We know that smoking has immediate adverse effects, reducing the ability of coronary arteries to Supplying blood to the heart, and our goal was to test whether the use of the electronic cigarette has similar effects, "he added.

After smoking 2 tobacco cigarettes, the researchers observed a 16% reduction in maximal coronary blood flow and a 19% increase in flow resistance. However, after their electronic cigarette use, no difference was observed in coronary blood flow and resistance compared to baseline measurement. "The results are impressive and indicate that, unlike tobacco, the Use of electronic cigarettes does not affect heart oxygenation, "Dr. Farsalinos said." However, we must be cautious and make it clear that this does not mean that there are no implications for long-term use. Of long-term use, but currently available evidence suggests that electronic cigarettes are, with far fewer harmful alternatives as compared to tobacco cigarettes. "
