EXPERIMENTAL MYOCARDIAL INFARCTION—AN ANIMAL MODEL
William E. Elzinga · 1969
1969 research showed magnets and iron particles could deliberately cause heart attacks in animals, proving magnetic fields can profoundly affect biology.
Plain English Summary
This 1969 research developed an animal model for studying heart attacks by using iron particles and magnets to create controlled coronary thrombosis (blood clots blocking heart arteries). The study aimed to create a reproducible experimental method for inducing myocardial infarction in laboratory animals. This represents early research into using magnetic fields and magnetic materials to manipulate biological processes in controlled laboratory settings.
Why This Matters
While this 1969 study predates modern EMF health research, it represents a fascinating early example of using magnetic forces to influence biological systems. The researchers used iron particles and magnets to deliberately create blood clots in coronary arteries, demonstrating that magnetic fields can have profound physiological effects when combined with magnetic materials in the body. This principle becomes relevant today as we consider how the iron in our blood and tissues might interact with the increasingly powerful magnetic fields from wireless devices, MRI machines, and other electromagnetic technologies. The science demonstrates that magnetic fields aren't just theoretical concerns but can produce measurable, significant biological responses. What this means for you is understanding that our bodies contain iron and other metals that can potentially interact with the magnetic components of EMF exposure in ways we're still discovering.

The animal model developed appears to simulate human myocardial infarction in many respects. The vessel is damaged at the site of attachment of the thrombus; enzyme activity (LDH, SGOT and CPK) is increased; cardiac arrhythmias are induced; electrocardiographic changes during myocardial ischemia, injury, and infarction resemble those seen in man; and secondary vessels are often occluded, as a result of embolism from the primary thrombus.
