Electromagnetic field therapy in cardiovascular diseases: A review of patents, clinically effective devices, and mechanism of therapeutic effects

In recent years, electromagnetic field (EMF) therapy has gathered much attention for its protective effects on cardiovascular functions. From reviewing the literature, it is evident that exposure to specific EMF spectrums, such as static- and extremely low frequency (ELF)- EMFs, by EMF-generating devices can be considered as a safe method for therapeutic means in various cardiovascular diseases, including heart failure, cardiac arrhythmias, and hypertension. This review article will describe registered patents and non-invasive clinically effective devices that generate EMF to target various cardiovascular diseases based on their mechanism of therapeutic effects.
