Studies Find Vaping can Reduce Risk of Heart Disease

Vaping Reduce Risk of Heart Disease

As the world continues to grapple with the health risks posed by traditional smoking, exciting new studies suggest an alternative path. According to recent research, smokers who transition to e-cigarettes could potentially lower their risk of heart disease by a significant 30-40%. This dramatic figure begs further examination, so let’s dive deep into this intriguing topic and unravel the science behind why vaping might be a safer alternative for your heart than traditional cigarettes.

E-Cigarette Use and Heart Health

The ever-evolving field of medical research often shines a light on perspectives previously unconsidered. One such groundbreaking study, published in the American Heart Association’s (AHA) journal in May 2022, is of particular interest. This research, a continuation of the Population Assessment of Tobacco and Health (PATH) study conducted in 2019, examined the relationship between the use of cigarettes and e-cigarettes (commonly known as vape kits) and their impact on heart health.

In the PATH study, researchers conducted a meticulous analysis of 24,027 participants from the original cohort. They focused on the use of traditional cigarettes and vaping kits among these individuals, comparing this data with self-reported incidents of cardiovascular disease (CVD), including conditions such as heart attack, bypass surgery, heart failure, or stroke.

E-Cigarettes and Reduced CVD Risk

The outcomes of this research were quite surprising, challenging previous notions of the impact of vaping on heart health. Participants who reported exclusive use of e-cigarettes demonstrated a 30-40% lower risk of CVD compared to those who smoked traditional cigarettes. In terms of numbers, among the group of traditional smokers, there were 569 reported incidents of CVD. In stark contrast, the vape users reported only 41 incidents. If we drill down further into specific conditions like heart attack, heart failure, or stroke, the number of incidents reported by traditional smokers was 242, while vapers reported a mere 15.

The Caveat: Dual Use Is Not Beneficial

However, the research also brought to light an important caveat that needs to be emphasized: the dual use of traditional cigarettes and vaping did not lead to a reduced risk of CVD. This finding underlines the importance of a complete transition from smoking to vaping if heart health improvement is the objective. Thus, smokers who are considering transitioning to vaping for health reasons should consider completely dropping traditional cigarettes rather than simply cutting back and supplementing with a vape kit.

How Does Smoking Lead to Heart Disease?

Understanding how smoking affects heart health requires delving into the mechanics of the human body. Smoking results in deposits of fat accumulating inside the body. These fat deposits adhere to the inner walls of the arteries, leading to a phenomenon known as arterial narrowing. This narrowing puts additional strain on the heart, compelling it to work harder to pump blood through these constricted passageways. Over time, this increased workload on the heart can lead to serious heart conditions, increasing the risk of heart attack or stroke.

Reaping Cardiovascular Benefits

A separate but complementary study by the University of Dundee titled “Cardiovascular Effects of Switching From Tobacco Cigarettes to Electronic Cigarettes” provides further insights into the benefits of switching from traditional smoking to vaping. The study found that such a transition could lower the risk of heart attack or stroke within just a few weeks, presenting a promising alternative for smokers.

Study Focus: Heavy Smokers

The study specifically targeted heavy smokers who had been consuming at least 15 cigarettes a day for a minimum of two years. These participants were instructed to switch to nicotine e-cigarettes for the duration of the study. In as little as a month, researchers noted marked improvements in the participants’ vascular health, which is a crucial factor in preventing heart disease.

How Does Vaping Lower Risk?

The main reason why vaping is believed to pose a lower risk to heart health compared to smoking is due to the significantly reduced presence of harmful chemicals. Vape devices deliver nicotine through a liquid (e-liquid), which is then heated to create a vapor that users inhale. In contrast to traditional cigarettes, which contain thousands of harmful chemicals resulting from the burning of tobacco, the e-liquid in vapes primarily consists of nicotine, propylene glycol, glycerin, and flavorings. These substances are far less damaging to the cardiovascular system compared to the numerous carcinogens and toxins found in tobacco smoke.

An Ongoing Journey: Caution Is Still Necessary

While the research into the benefits of vaping over smoking for heart health presents a promising alternative, it is important to remember that e-cigarettes are not risk-free. Further research is necessary to understand the long-term effects of vaping, especially as it relates to heart health. Health experts also caution against non-smokers taking up vaping, as nicotine – the common component in both traditional cigarettes and e-cigarettes – is addictive and carries its own risks.


The advent of e-cigarettes has opened up new conversations about smoking and its health risks. While it’s clear that vaping is not without its own risks, the potential to reduce the risk of heart disease by switching from traditional cigarettes to vaping is an encouraging development. Nevertheless, it is crucial to keep in mind that the goal should always be complete cessation of nicotine use for the best possible heart health.
