A Revolution in the Treatment of Cardiovascular Disorders
Share this article:
In short: Photobiomodulation is a noninvasive method that converts light energy from low-intensity LEDs or lasers into cellular energy to stimulate tissue repair. When applied to cardiovascular disorders, it may reduce infarct size, improve cardiac function through enhanced mitochondrial activity, lower blood pressure, and promote peripheral circulation. However, standardized protocols and further clinical trials are still needed to confirm its effectiveness.
Photobiomodulation: A Revolution in the Treatment of Cardiovascular Disorders
Introduction to Photobiomodulation
Photobiomodulation (PBM), also known as low-level laser therapy, is a noninvasive medical method. It is gaining popularity and could revolutionize the treatment of cardiovascular disorders, a leading cause of death worldwide.
Understanding Photobiomodulation
Photobiomodulation uses low-intensity lasers or LEDs to stimulate the healing of damaged or diseased tissue. This technique converts light energy into cellular energy, triggering beneficial biological responses.
The Potential of Photobiomodulation for Cardiovascular Disorders¹
Ischemic heart disease: It may reduce the size of the heart attack by improving blood flow to the heart tissue.
Heart Failure: Research shows an improvement in cardiac function, attributed to improved mitochondrial function and a reduction in oxidative stress.
High Blood Pressure: PBM can lower blood pressure by improving endothelial function and reducing oxidative stress.
Peripheral Artery Disease: This therapy may improve blood flow in the peripheral arteries, thereby relieving symptoms.
Challenges and Future Prospects
Despite its potential, photobiomodulation faces challenges such as the need to standardize treatment protocols and conduct more clinical trials to confirm its effectiveness.
Photobiomodulation is a promising therapeutic approach that could revolutionize the treatment of cardiovascular disorders. Although further research is needed to refine its mechanism of action and establish standardized protocols, PBM is poised to become a major breakthrough in cardiovascular medicine.
Our summary of the 58 publications on photobiomodulation that were published or indexed in June 2026. Topics include: oral mucositis confirmed by a multicenter randomized trial; PBM for pain associated with temporomandibular disorders; and more recent research in cognition, sleep, and presbyopia.
Photobiomodulation and Chemotherapy: The Study That Restores Memory
A study by the Valenciennes Hospital (CHV) confirms that transcranial photobiomodulation (using the Vielight Duo 4 headset) restores memory after chemotherapy: 93.5% of patients showed improvement.
Our May 2026 scientific review compiles 30 publications on photobiomodulation, including several meta-analyses and randomized trials. Overview by clinical field: pain, supportive oncology, neurology, oral health, sports medicine, wound healing, and ophthalmology.
As of April 2026, 144 PubMed publications on photobiomodulation had been indexed. Our team selected 18 notable clinical studies in the fields of neurology, supportive oncology, ophthalmology, dentistry, sports medicine, and pain management.
