Can E-Cigarettes Cause Heart Disease First smokeless, non-tobacco cigarette device was patented in 1967. This non-tobacco cigarette was thought to be a safe and harmless method of smoking by replacing burning tobacco and paper with heated, moist, flavored air. In 2003, first generation e-cigarette was made in China as a safer and cleaner way to inhale nicotine as a tobacco cessation resource. It used a piezoelectric element to vaporize the liquid containing nicotine diluted in a propylene glycol solution. E-cigarettes are sometimes called e-cigs, vapes, e-hookahs, vape pens, and electronic nicotine delivery systems (ENDS). Some e-cigarettes look like regular cigarettes, cigars, or pipes while some look like USB flash drives, pens, and other everyday items. An aerosol is produced by e-cigarettes by heating a liquid that usually contains nicotine, flavorings, and other chemicals. The liquid is sometimes called e-juice, e-liquid, vape juice, or vape liquid. Users inhale e-cigarette aerosol into their lungs. Bystanders may breathe in this aerosol when the user exhales it into the air. Since the introduction of e-cigarettes into the American market in 2007, they are gaining popularity, with as many as 15 million Americans currently using them. E-cigarettes have been marketed as a healthy alternative to traditional combustible cigarettes and as an effective method of smoking cessation. However, according to the Center for Disease Control and Prevention (CDC), e-cigarette aerosol is actually not harmless water vapor. The e-cigarette aerosol can contain harmful and potentially harmful substances, including nicotine; ultrafine particles that can be inhaled deep into the lungs; flavorings like diacetyl, a chemical linked to a serious lung disease; volatile organic compounds; cancer-causing chemicals; and heavy metals like nickel, tin, and lead. The aerosol can expose both themselves and bystanders to harmful substances.
In fact, a study published in January 2015 in ‘The
New England Journal of Medicine’ reported that the lifetime cancer risk of using
e-cigarettes long term is estimated to be 5 to 15 times higher than that of
smoking a pack of cigarettes a day, due to the toxic substance formaldehyde in
the e-cigarette vapor.
But, will e-cigarettes cause heart disease? There have been evidences linking smoking to heart disease because of nicotine. E-cigarettes have nicotine, which is known to increase heart rate and blood pressure. This is because nicotine narrows the arteries in the heart and throughout the body. Over time, this can cause serious harm to the cardiovascular system and lead to heart attacks, strokes, and heart failure. Nicotine can worsen the condition of people with coronary artery blockages and people with congestive heart failure. They might develop chest pain or increased symptoms of heart failure. Nicotine can also provoke episode for a person with an arrhythmia. During The American College of Cardiology's 68th Annual Scientific Session and Exposition held between March 16 to 18, 2019, researchers at the University of Kansas School of Medicine revealed that e-cigarette users were 34 percent more likely to have a heart attack, 25 percent more likely to have coronary artery disease, and 55 percent more likely to experience emotional distress, after adjusting for other cardiovascular disease risk factors including age, sex, body mass index, high cholesterol, high blood pressure, and traditional smoking. In the study, the researchers conducted cross-sectional analysis on data from the CDC’s 2014, 2016, and 2017 National Health Interview Survey. A total of 96,467 respondents were asked questions about ever-cigarette or related tobacco product use, ever-use of e-cigarettes, and frequency of use.In another study that was published November 13, 2019 in the ‘European Heart Journal’, researchers reported that e-cigarette smoking immediately compromised the ability of arteries to dilate (expand) in response to increases in the need for blood flow, hence posing an independent risk of having had a heart attack in smokers. They also found that heated aerosol was more toxic than the unheated e-liquid.
Health advocates around the world, from the
American Heart Association (AHA) to the World Health Organization (WHO), are
calling for stricter e-cigarette regulations because of possible heart and lung
health risks. Many countries, including Australia, Hong Kong, Singapore already
ban possession and sale of e-cigarettes. Date: March 5, 2020
