Title: Analysis of the MF influence on Rheological properties of healthy blood

Location in PEMF Global Library: Circulation folder
Published: 2013

Applied Frequencies: 180–195 Hz
Available in: iMRS Prime Trial
 
Abstract: The study was performed on blood samples taken from 25 healthy nonsmoking persons and included comparative analysis of the results of both the standard rotary method (flow curve measurement) and the oscillatory method known also as the mechanical dynamic analysis, performed before and after exposition of blood samples to magnetic field.
 
Conclusion: The data obtained from the flow curve measurements complemented by hematocrit and plasma viscosity measurements have been analyzed using the rheological model of Quemada. No significant changes of the studied rheological parameters have been found.

Title: The effect of prolonged exposure to low frequency electromagnetic fields on mechanical activity of isolated aorta of male rats

Location in PEMF Global Library: Circulation folder
Published: 2019

Applied Frequencies: 50 Hz
Available in: iMRS Prime Trial
 
Abstract: This study was designed to assess the effects of long term exposure of extremely low frequency EMF of 100 and 500 µT on vascular activity in rats.
 
Conclusion: Vasorelaxation response to acetylcholine was not significantly different between three groups (p=0.60). However, the vasoconstriction response to phenylephrine in 500 µT group was less than those of other groups (p=0.035).

Title: Pulsed electromagnetic field improves cardiac function in response to myocardial infarction

Location in PEMF Global Library: Circulation folder
Published: 2014

Applied Frequencies: 30 ± 3 Hz
Available in: Omnium1, iMRS Prime Trial
 
Abstract: Here, we examined whether PEMF therapy facilitate cardiac recovery in rat myocardial infarction (MI), and the cellular/molecular mechanisms underlying PEMF-related therapy was further investigated. The MI rats were exposed to active PEMF for 4 cycles per day (8 minutes/cycle, 30 ± 3 Hz, 5 mT) after MI induction.
 
Conclusion: The data demonstrated that PEMF treatment significantly inhibited cardiac apoptosis and improved cardiac systolic function. Moreover, PEMF treatment increased capillary density, the levels of vascular endothelial growth factor (VEGF) and hypoxic inducible factor-1α in infarct border zone. In conclusion, PEMF therapy preserves cardiac systolic function, inhibits apoptosis and triggers postnatal
neovascularization in ischemic myocardium.

Title: Novel protective effects of pulsed electromagnetic field ischemia/reperfusion injury rats

Location in PEMF Global Library: Circulation folder
Published: 2016

Applied Frequencies: 25 Hz
Available in: Omnium1, iMRS Prime Trial
 
Abstract: In the present study, we investigated for the first time whether PEMF treatment could improve the myocardial ischaemia/reperfusion (I/R) injury and uncovered its underlying mechanisms.
 
Conclusion: In our study, we demonstrated for the first time that extracorporeal PEMF has a novel effect on myocardial I/R injury. The number and function of circulating endothelial progenitor cells (EPCs) were increased in PEMF treating rats. The in vivo results showed that per-treatment of PEMF could significantly improve the cardiac function in I/R injury group. Therefore, our data indicated that PEMF could be a potential candidate for I/R injury.
