People who use conventional (combustible) cigarettes and e-cigarettes do not reduce their risk of cardiovascular disease compared to people who exclusively use traditional cigarettes, according to new research published today in the leading peer-reviewed journal of the American Heart Association. Rotation.

Smoking conventional cigarettes is well-established as a contributor to a wide range of serious health conditions. Nearly 1 in 5 deaths in the United States each year are attributable to cigarette smoking and exposure to secondhand smoke, according to the American Heart Association’s Heart Disease and Stroke Statistics – 2022 update. E-cigarettes, which contain many toxic chemicals, are becoming increasingly popular. As another way to consume nicotine.

“The fact that dual use—using both conventional combustible cigarettes and e-cigarettes—has the same cardiovascular risk as smoking only is an important finding because many Americans smoke e-cigarettes in an effort to reduce smoking to what they see as smoking,” said Andrew C. Stokes, Ph.D., author of “It is common for people to try to switch from conventional cigarettes to e-cigarettes and get into trouble using both products,” the study’s senior author, and assistant professor in the Department of Global Health at the Boston University School of Public Health.

To examine the association between cardiovascular disease, e-cigarette use and the dual use of conventional and e-cigarettes, the researchers reviewed data from the Population Assessment Tobacco and Health (PATH) Study, a nationwide representative study with five annual waves of self. – Information on health and nicotine product use collected from 2013 to 2019. After adjusting for age, gender, and race/ethnicity, the study focused on more than 24,000 adults, 50% of whom were 35 years of age or younger, and 51% of women. .

Participants were classified as smokers if they smoked more than 100 combustible cigarettes in their lifetime and reported current cigarette smoking during any round of the data collection period. E-cigarette users were identified by participants self-reporting of any e-cigarette use during any data collection round. Group ratings were 1) no e-cigarette use or traditional cigarette smoking (14,832 subjects; this group can include former smokers or former e-cigarette users); 2) exclusive e-cigarette use (822 people); 3) the use of only conventional cigarettes (6515 people); or 4) dual use of both conventional cigarettes and e-cigarettes (1858 people).

The analysis defined cardiovascular status as any self-reported diagnosis of heart attack, bypass surgery, heart failure or other heart conditions or stroke in the past 12 months. The researchers also evaluated a separate score for self-reporting only heart attacks, heart failure, or stroke. The review found more than 1,480 cases of any cardiovascular disease and more than 500 cases of heart attack, heart failure or stroke.

An analysis of all study participants found:

  • Compared with people who smoked conventional cigarettes only, people who smoked conventional cigarettes and used e-cigarettes also had no significant differences in the risk of cardiovascular disease nor in the risk of heart attack, heart failure, or stroke.
  • People who used e-cigarettes only and people who used both conventional cigarettes and e-cigarettes were younger than people who used neither product: 62% of people who used e-cigarettes only and 54% of double users were under 35 years old, compared to Classifying 51% of participants as non-users, they did not smoke conventional cigarettes or use e-cigarettes.

The researchers noted that, compared to smoking exclusive conventional cigarettes, exclusive use of e-cigarettes was associated with 30%-40% lower self-reported cardiovascular disease, although the association was only significant for any cardiovascular outcome, which includes conditions such as heart Congenital myocarditis or myocarditis (41 events reported by e-cigarette users vs 569 events reported by cigarette smokers), not specific to heart attack, heart failure or stroke (15 events reported by e-cigarette users vs 242 reported events by cigarette smokers). Given the low numbers of self-reported results reported by e-cigarette users, the researchers concluded that more data is needed in this area.

“While the PATH study provides baseline longitudinal data on the use of conventional cigarettes and e-cigarettes, as well as on outcomes such as cardiovascular events, the data are self-reported, the study duration is short and the event rate remains low – especially in young adults. Because e-cigarette use is still Relatively new, there isn’t yet a solid body of long-term evidence to determine the ultimate risk of using these products over time, so we look forward to more data from this and others,” said Rose Marie Robertson, MD, FAHA, vice president, chief medical and scientific officer for the American Heart Association. and co-director of the National Institutes of Health/Food and Drug Administration-funded Association of Tobacco Administration Center for Regulatory Science, which pported the study. “People should know that e-cigarettes contain addictive nicotine and toxic chemicals that may have adverse effects on the heart system. blood vessels and their health in general.

Among the study’s many limitations, an important factor that the researchers noted was the small number of individuals and cardiovascular events in the exclusive e-cigarette use group. While only 15 people who used e-cigarettes exclusively reported a diagnosis of heart attack, heart failure, or stroke, the number of individuals and events was too low to draw definitive conclusions about the effects of exclusive use of e-cigarettes in the study sample.

“Many smokers who try to use e-cigarettes to quit smoking traditional cigarettes actually continue to use both products, becoming dual users, as we haven’t seen a reduction in cardiovascular risk,” Stokes said. “We are concerned that any recommendation for e-cigarette use for smoking cessation may lead to an increase in dual use, as well as the initiation of e-cigarette use among young adults and those who have never smoked cigarettes.”

“E-cigarettes are not FDA approved for smoking cessation. We urge anyone who smokes and is interested in quitting to speak with their physicians and health care team about other effective FDA-approved smoking cessation options,” Robertson said.
