High adrenaline levels, oxidative stress seen in comparison with nonsmokers
Electronic cigarettes may increase the risk of heart disease, researchers at UCLA report.
The team found that two risk factors for heart disease were elevated in 16 e-cigarette users compared with 18 nonsmokers.
“The pattern was spot-on” for what has been seen in heart attack patients and those with heart disease and diabetes, says cardiologist Holly Middlekauff, a coauthor of the study published online February 1 in JAMA Cardiology.

Even so, Ambrose called the study interesting, noting
