Vaping improves myocardial heart functions in smokers, says study

Posted by

A recently released e-cig study by Dr. Konstantinos E Farsalinos from the Onassis Cardiac Surgery Center in Kallithéa, Greece, suggests that vaping is good for the heart compared to smoking. In fact, the benefits are so significant that the research shows smoking even a single cigarette has immediate, negative effects to myocardial functions.

The Farsalinos team began with a speci9ally selected group of volunteer participants. 40 vapers and 36 smokers between the ages of 30 and 41 took part. The smokers each had a history of smoking at least 15 cigarettes per day for at least five years. The vaping group was comprised completely of former-smokers who had remained cigarette- or tobacco-free for a period of at least 30-days.

Overview of the Farsalinos vaping study

Throughout the course of the Farsalinos vaping study, the team of scientists measured several biomarkers in each of the participants. They also evaluated a long list of myocardial heart functions both before and after engaging in their related activity. Smokers were sent to a separate laboratory than vapers to avoid possible cross-contamination.

Vapers were asked to engage in e-cig usage for seven minutes while using the same brand of electronic cigarette containing the same 11 mg nicotine e-liquid. Meanwhile, the scientists measured for the following myocardial functions.

  • Systolic Blood Pressure
  • Diastolic Blood Pressure
  • Heart Rate
  • IVRT Corrected to Heart Rate (IVRTc)
  • Left Ventricle (LV) Mass Index and Diameter
  • Isovolumetric Relaxation Time (IVRT)
  • Glucose Levels
  • Triglyceride Levels
  • Cholesterol Levels
  • Myocardial performance index
  • And multiple other pertinent cardiovascular functions


"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."

- Per the myocardial e-cig study Acute effects of using an electronic nicotine-delivery device (electronic cigarette) on myocardial function: comparison with the effects of regular cigarettes located for review on the medical journal BMC Cardiovascular Disorders.

What the research team discovered is that the group of smokers exhibited immediate signs of oxidative stress, myocardial inflammation, and other related heart damage after smoking even a single cigarette. Meanwhile, the vapers showed no significant negative effects in any of these same related areas. For anti-vapers who often claim that vaping is just as deadly as smoking, the Farsalinos research seemingly proves the contrary.
