Vaping has no myocardial effects, but one cigarette has instant negative results

A recently published survey from the Georgia State University Tobacco Center of Regulatory Science (GSU-TCRS) is mow indicating that a rising number of Americans now believe that vaping is just as deadly as smoking.  Another approximately 10 percent actually perceive vaping to be even toxic than combustible tobacco products.

The U.S. Food and Drug Administration (FDA) continues to flood the general population with misinformation regarding everything from teen vaping rates to the significance of flavored e-liquids for adult smokers trying to quit.  This constant barrage of distorted representations of the facts is leading many scientists to conduct studies of their own to validate or invalidate these seemingly outrageous claims.

One group of reputable scientists out of Greece has conclusively determined that vaping significantly and immediately exhibits positive effects on the heart while smoking even a single cigarette produces immediate adverse effects. Led by Dr. Konstantinos E. Farsalinos of the Onassis Cardiac Surgery Center, the study is entitled Acute effects of using an electronic nicotine-delivery device (electronic cigarette) on myocardial function: comparison with the effects of regular cigarettes. The full report is readily available in the medical journal BMC Cardiovascular Disorders.

Switching to vaping is good for myocardial health

The Onassis research team began by soliciting a group of volunteers – both smokers and vapers – to engage in a clinical trial where various cardiovascular biomarkers would be measured and compared for a detailed analysis.  Heart functions measured included Diastolic and Systolic Blood pressures, Isovolumetric relaxation time (IVRT) rates, IVRT corrected to heart rates (IVRTc), triglyceride, glucose, and cholesterol levels, left ventricle (LV) diameters and mass index, and several other factors.

  • Of the 81 participants originally chosen, 76 completed the study.
  • 40 vapers and 36 smokers were carefully selected.
  • Average ages of the smokers and vapers were 36 and 35 respectively.
  • 68 of the remaining 76 members at the end of the study were men. 4 were women.
  • Each of the vaping-only group also self-identified as former smokers.

The scientists would periodically call each participant into the laboratory while asking them to either smoke or vape in a separately enclosed space.  Vapers vaped in one room.  Smokers smoked in another so as to avoid possible cross contamination.  Both before and after the experiment, all myocardial functions related to the study were carefully measured.  They were also monitored throughout the experiment, as well.

According to the published findings, the participants of the vaping-only group exhibited no measurable changes – either positive or negative – in the various heart functions being monitored.  Conversely, each of the members of the smoking group exhibited adverse reactions in nearly every category almost immediately after taking the first puff of a 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."

Just last month, a report published by co-authors from the University of Kansas was making the rounds of social media.  The paper mistakenly claims that vaping increases the risks of heart attacks and depression.  The article was also widely and immediately debunked by the most reputable members of the scientific community, largely for its failure to pre-qualify the participants’ health before the alleged experiments took place.  Other disqualifying factors came into play as well (see the below link for a full report).

Smokers with heart problems should always first consult their physician before attempting to quit smoking.  Whether considering the use of conventional nicotine replacement therapies, vaping, or the old-fashioned cold-turkey method, performing proper due diligence is critical.
