Daily use of e-cigarettes combined with traditional smoking can lead to a five-fold increase in the odds of heart attack, according to study which also found that vaping alone doubles the risk.


The study, published in the American Journal of Preventive Medicine, examined the relationship between e-cigarette use and heart attacks, and begins to fill the understanding of the effects of e-cigarettes on long-term health.


"Most adults who use e-cigarettes continue to smoke cigarettes," said senior author Stanton Glantz, a professor at University of California - San Francisco in the US. "While people may think they are reducing their health risks, we found that the heart attack risk of e-cigarettes adds to the risk of smoking cigarettes," Glantz said.


"Using both products at the same time is worse than using either one separately. Someone who continues to smoke daily while using e-cigarettes daily increases the odds of a heart attack by a factor of five," he said.
