According to a recent extensive study in the Vaping United States, there’s now evidence contradicting the belief that e-cigarettes offer a safer alternative to traditional smoking. The study reveals a concerning finding: individuals who have vaped at any point in their lives face a 19 percent higher risk of developing heart failure.

Vaping
Heart failure, a condition characterized by the heart’s inability to effectively pump blood due to muscle stiffness or weakness, poses serious health risks. Dr. Nishith Chandra, Principal Director of Interventional Cardiology at Fortis Escorts Heart Institute in Delhi, explains that nicotine in vaping solutions elevates heart rate and blood pressure, placing undue stress on the heart with prolonged use. Additionally, it constricts blood vessels, reducing flexibility and causing fibrosis.
Despite India’s prohibition on the manufacture, import, and sale of e-cigarettes, these products persist in the grey market. A significant portion of the population, approximately 23 percent, reportedly uses e-cigarettes in India, with eight percent using them daily, according to last year’s survey in Preventive Medicine Reports. However, the Global Adult Tobacco Survey estimates the current e-cigarette user population to be only 0.02 percent of the total population.
What exactly is vaping?
Vaping, or the use of e-cigarettes, involves electronically heating a solution comprising glycerin, flavorings, and nicotine—the addictive substance found in traditional cigarettes. While smokers seek nicotine, it’s the tar in cigarettes that proves fatal. E-cigarettes were initially promoted as aids for smoking cessation due to this distinction.
Nonetheless, there’s insufficient data demonstrating the effectiveness of e-cigarettes in aiding smoking cessation. In fact, users often end up using both cigarettes and e-cigarettes concurrently. Furthermore, the diverse flavors of e-cigarettes may entice non-smokers to adopt the habit. In the United States, data indicates that e-cigarettes are the most prevalent tobacco product among students.
Insights from the recent study
The study, which observed 170,000 vapers over a 45-month period, identified 3,242 cases of heart failure among them. Results revealed that individuals who had used e-cigarettes at any time were 19 percent more likely to develop heart failure compared to non-users. Researchers controlled for smoking history and other heart disease risk factors.
Lead author Yakubu Bene-Alhasan, a resident physician at MedStar Health in Baltimore, emphasized the significant disparity observed in the study’s findings. He cautioned about the potential health consequences, particularly concerning heart health, and highlighted the increasing body of research linking e-cigarettes to harmful effects, challenging previous assumptions regarding their safety.
Understanding the heightened risk of heart failure
The study also highlighted an increased likelihood of a specific type of heart failure known as heart failure with preserved ejection fraction (HFpEF). This condition involves stiffening of the heart muscles, impairing proper filling between contractions. Dr. Chandra notes that daily e-cigarette use damages blood vessel linings, inhibits new blood vessel development, and fosters inflammation, thereby elevating the risk of heart attacks and strokes.
Additional health implications of vaping
Beyond heart health concerns, nicotine in e-cigarettes can perpetuate addiction rather than facilitate smoking cessation. Accidental exposure to vaping liquid may result in acute nicotine poisoning. Moreover, due to the lack of standardization in e-liquid composition, many vaping products emit chemicals linked to lung diseases, cancer-causing agents, and heavy metals.
Furthermore, e-cigarette or vaping product use-associated lung injury (EVALI) presents symptoms such as shortness of breath, chest pain, and severe breathing difficulties. Suspected causes include contamination with Vitamin E and exposure to formaldehyde and acetaldehyde, which can damage lung tissue. Additionally, a chemical called diacetyl found in vape liquid can trigger popcorn lung—a condition characterized by air sac inflammation and permanent narrowing of airways.
