Research shows switching to vaping measurably improves myocardial health
Much has been said about the now-debunked research co-authored by the notorious Stanton Glantz claiming that vaping causes heart attacks. The fictitious conclusions of the study received widespread attention by falsely reporting that some 38 individuals experienced cardiac events after transitioning from smoking to e-cigarettes. Upon farther review, however, Dr. Brad Rodu of the University of Louisville discovered that the alleged cardiac events actually occurred years before rather than immediately after the individuals switched to vaping.

For those who might require additional proof, another study conducted by the research team of Dr. Konstantinos E. Farsalinos of the Onassis Cardiac Surgery Center in Greece further indicates that adult smokers who transition to e-cigarettes experience vast improvements in myocardial health almost instantly. The research is well-documented in the peer-reviewed study entitled, Acute effects of using an electronic nicotine-delivery device (electronic cigarette) on myocardial function: comparison with the effects of regular cigarettes (BMC Cardiovascular Disorders).
Overview of the Farsalinos vaping study on myocardial functions
Oddly, the bogus paper published by Stanton Glantz is not the first time that conspiracy-minded anti-vaping activists have published counterfeit research that ignores proper scientific protocols. In August 2017, another such document attempting to falsely link vaping to heart attacks surfaced online and began spreading across social medial.
The 2017 publication has the rather alarming title, E-cigarettes are as dangerous as smoking - just ONE puff could be all it takes to increase the risk of a heart attack. It was immediately debunked by Dr. Farsalinos and others in the scientific community while calls for an immediate retraction by many members of academia were essentially ignored by the publishing website. However, the publication of such a dangerously untrue paper is what likely contributed to Farsalinos engaging in his own scientific research involving vaping’s potential effects on the heart.

The Greek researchers began by soliciting the assistance of 81 participants, 76 of which completed the study successfully. 40 were regular vapers of at least one month who also self-identified as former smokers. The 36 remaining participants were active smokers of at least five years with a daily cigarette intake of at least fifteen. The average age of the participants was 35.5 years, and both men and women participated in the clinical trial.
During the experiment, smokers were required to use the same combustible tobacco products and vapers were asked to use the same 7ml nicotine e-liquid. Each participant was then asked periodically to vape or smoke in specially designated laboratories while the researchers monitored, collected, and analyzed multiple myocardial functions.
To avoid possible cross contamination concerns, vapers would use one room. Smokers would use another. Examples of myocardial functions monitored include the following.
- Myocardial performance index
- Left ventricle (LV) Diameter
- Standing Heart Rate and Blood Pressure
- Diastolic Blood Pressure
- Systolic Blood Pressure
- Isovolumic relaxation time (IVRT)
- Isovolumic relaxation time corrected to heart rate (IVRTc)
- Triglyceride, Glucose, and Cholesterol levels
What the Farsalinos team determined is that the vaping group of participants experienced no measurable changes in the various myocardial functions and haemodynamic parameters after seven minutes of e-cig usage. Conversely, the smoking group experienced almost immediate adverse effects after smoking even a single combustible tobacco cigarette.
"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."
As the war on vaping continues to escalate, the myth that vaping causes heart attacks seems to resurface online every few months. Unfortunately, many surveys now indicate that the American public is beginning to believe – wrongly - that vaping is just as deadly as smoking. Research by such dedicated professionals as Dr. Konstantinos E. Farsalinos and Dr. Brad Rodu go a long way in helping to educate the misinformed about the truly lifesaving benefits of vaping.
