Vapeboss – A study titled "E-Cigarette Aerosol Reduces Left Ventricular Function in Adolescent Mice," exposed mice to a nicotine-containing e-cigarette mixture in the laboratory. Professor of nursing and medicine at The Ohio State University College of Nursing, Loren Wold, PhD, said that significant cardiovascular effects were observed in adolescent male mice.

“When we exposed adolescent males, we had significant cardiovascular effects,” Professor Wold explained. In regard to female mice, heart function was not affected at all, which the research team attributed to the possibility of higher levels of an enzyme called CYP 2A5. “The theory is that this enzyme is much higher, able to break down nicotine faster,” Wold said.

Switching from smoking to vaping improves heart health

On the other hand, new findings reported in a new study published in Circulation, indicate that smokers who switch exclusively to vaping reduce their risk of heart disease by 34%. Using a longitudinal approach, the research team analyzed data from 32,000 adult tobacco users who participated in the nationally representative Population Assessment of Tobacco and Health (PATH) over a six-year period from 2013 to 2019. The researchers assessed vaping and smoking patterns, and then compared them with self-reported incidents of heart disease, such as stroke, heart attack, and heart failure.

The collected data showed that compared to non-smokers, smokers experienced an 1.8 times higher risk of heart disease, while the risk for exclusive vapers was not statistically different. For this effect, the study concluded that there was a significant association between smoking and heart disease, but not between vaping and heart disease.
