No, vaping is NOT bad for the heart. In fact, research shows the exact opposite is true.
The American Heart Association (ALA) often claims that vaping is bad for cardiovascular health, but research shows the exact opposite to be true. When compared to smoking, nicotine-based vapor products and electronic cigarettes have proven to have a dramatic and almost immediate positive impact on the myocardial system. In fact, switching to vaping provides near-instantaneous improvements in blood pressure, glucose, cholesterol, and triglyceride levels, according to a recent study. Meanwhile, smoking even a single combustible tobacco cigarette produces immediate negative consequences.
In a recent vaping study entitled Acute effects of using an electronic nicotine-delivery device (electronic cigarette) on myocardial function: comparison with the effects of regular cigarettes, researchers conducted a series of tests involving 81 participants. Published in the medical journal BMC Cardiovascular Disorders by lead author Dr. Konstantinos E. Farsalinos of the Onassis Cardiac Surgery Center in Kallithéa, Greece, the paper offers the following conclusions.
“Although acute smoking inhalation caused a delay in LV myocardial relaxation in smokers, electronic cigarette use was found to have no such immediate effects in daily users of the device. This short-term beneficial profile of electronic cigarette compared to smoking, although not conclusive about its overall health-effects as a tobacco harm reduction product, provides the first evidence about the cardiovascular effects of this device. Since awareness and use of electronic cigarettes are continuously rising, more studies are urgently needed, focusing on the pathophysiological mechanisms of disease where smoking is implicated and ultimately on long-term effects. Such studies will provide additional scientific data to public health authorities so that they decide on the regulatory status of this product.”
The Farsalinos research team began by dividing the participants into three different groups: Smokers-turned-vapers, continuing smokers, and never-vapers-never-smokers as the control sample. The vaping-only group were not allowed to engage in dual usage of tobacco cigarettes and vaping products. They were also restricted to using the same vaping devices and e-liquids.
Likewise, all smokers were provided the same over-the-counter combustible tobacco cigarettes for use during the experimentation phase. The study guidelines were so strict that five different participants were kicked out of the study for failing to adhere to these fundamental rules.
Of the remaining 76 people, 32 men and 4 women comprised the smoking-only group. The vaping-only group consisted of 36 men and 4 women. The average age of all participants was 35 years.
Overview of the Farsalinos vaping study
Throughout the course of the clinical trial, researchers asked each participant to engage in smoking or vaping for a full seven minutes while their cardiovascular systems were being carefully monitored. To keep the scientific results uncompromised and optimally accurate, smokers were restricted to one room, and vapers were restricted to another. Heart functions monitored include the following.
- Diagnostic Blood Pressure Levels
- Systolic Blood Pressure Levels
- Isovolumic Relaxation Time (IVRT rate)
- Left Ventricle (LV) Diameter
- Left Ventricle (LV) Mass Index (MI)
- Cardiovascular performance index
- Standing Heart Rate
- Cholesterol, triglyceride, and glucose levels
What the Farsalinos research team discovered is that the vaping-only group experienced a tremendous boost in heart health overall. On the other hand, the smoking-only group witnessed significant myocardial abnormalities almost instantly.
"This is the first study to examine the acute effects of electronic cigarette use on myocardial function. No adverse effects on LV [left ventricular] myocardial function were observed after using electronic cigarette with nicotine-containing liquid for 7 minutes. On the contrary, significant changes in diastolic function parameters were found after smoking 1 tobacco cigarette."
"This study provides the first clinical evidence that electronic cigarettes have less acute adverse effects on myocardial function when compared to tobacco cigarettes."
Why do so-called public health groups like the American Heart Association, the American Lung Association, and the Campaign for Tobacco-Free Kids continue to spread lies and misinformation about the health benefits of vaping? As public health expert Dr. Michael Siegel of Boston University points out, each of these organizations are deep in the pockets of Big Pharma – manufacturers of competing smoking cessation like nicotine patches, gums, and lozenges. GlaxoSmithKline alone- manufacturer of Nicorette Gum – has contributed an astonishing $1.4 million in the form of “contributions” and research grants in recent years to organizations like the AHA.
