The rate of heart attacks was higher by 34% in the vapor, compared to non-vapor, even taking into account other risk factors.

The vapor suffer more frequently from heart disease than non-vapor, according to a major preliminary study unveiled Thursday in the United States and which does not establish a cause and effect relationship.

The study of the effects of electronic cigarettes is relatively recent, as they have emerged in the last decade. In the United States, their rapid growth has triggered panic among the health authorities. In secondary schools, the number of students vapotant has increased from 78% in 2018 compared to 2017.

The electronic cigarettes do not contain many of the carcinogens present in conventional cigarettes, but researchers and public health experts are raising questions about the possible consequences of the high temperature heating of the goods contained in the cartridge liquid, beyond the powers addictive known of the nicotine.

In this study, which will be presented next week at a meeting of the american College of cardiology, the researchers used the questionnaires of near 100 000 people from the Centres of control and prevention of diseases (CDC) in 2014, 2016 and 2017.

The rate of heart attacks was higher by 34% in the vapor, compared to non-vapor, correcting for the risk factors of age, sex, body mass index, cholesterol, blood pressure, and history of smoking.

For arterial diseases, the increase was 25 % ; for depression and anxiety, 55 %.

“Until now, we knew little about the cardiovascular events associated with the use of electronic cigarettes “, said the doctor Mohinder Vindhyal, a professor at the University of Kansas and lead author of the study. “These data should be an alarm signal and trigger actions and an awareness on the danger of electronic cigarettes. “

The data also show that the risk in smokers of tobacco, compared to non-smokers, was even higher.

This kind of studies are purely observational and do not prove that the smoking triggers cardiovascular disease ; the researchers argue, moreover, no biological mechanism. Other studies, following of the vapor over a long period of time, will be needed to achieve this.
