MedicalResearch.com: What is the background for this study? What are the main findings? 

Response: Although the health effects of e-cigarettes remains unclear, e-cigarettes have been marketed as an approach for smoking cessation. Previous studies have reported an increase in e-cigarette use in US people since 2010. The current study showed that from 2014 to 2016, there was an increase in ever use of e-cigarettes but decline in current use of e-cigarettes.  Continue reading

Response: E-cigarettes are the fastest rising tobacco product in the US today, but almost nothing is known about their cardiovascular effects. Rather than wait decades for epidemiological data in e-cigarette users to become available, we reasoned that investigations into the known mechanisms by which tobacco cigarettes increase heart disease would provide insights into the health risks of e-cigarettes.

We focused on 2 critical mechanisms:
1) cardiac adrenaline activity, and
2) oxidative stress, measured in chronic e-cigarrete users compared to matched, healthy controls.

The major findings were that, compared to healthy controls, e-cig users had increased cardiac adrenaline activity (measured by a technique called “heart rate variability”). Furthermore, compared to healthy controls, the e-cig users had increased susceptibility to oxidative stress.
