Insights
Electrical muscle stimulation (EMS) is an FDA-approved method to prevent blood clots. This review suggests EMS may work by stimulating a fourth factor beyond Virchow
Area of Science:
- Medical Science
- Physiology
- Thrombosis Research
Background:
- Electrical muscle stimulation (EMS) is an FDA-approved method for preventing blood clots (thromboprophylaxis).
- Thrombus formation is traditionally explained by Virchow's triad: vessel wall, blood flow velocity, and blood composition.
Purpose of the Study:
- To review evidence supporting EMS thromboprophylaxis.
- To investigate EMS efficacy beyond the scope of Virchow's triad.
- To propose a novel pathophysiological mechanism for thrombogenesis.
Main Methods:
- Review of existing scientific literature and evidence.
- Analysis of theoretical pathophysiological mechanisms.
- Hypothesis formulation based on observed phenomena.
Main Results:
- EMS efficacy in certain cases exceeds explanations based on Virchow's triad.
- Observed phenomena like higher VTE in lower extremities and synergistic effects with compression devices suggest additional factors.
- A hypothesis is proposed for a fourth thrombogenetic factor: neural supply to veins.
Conclusions:
- A novel pathophysiological mechanism of thrombogenesis, involving neural supply, is supported by the evidence.
- The role of EMS in thromboprophylaxis may be expanded by considering this fourth factor.
- Further exploration could reveal new therapeutic targets for preventing blood clots.
Introduction:
Electrical muscle stimulation (EMS) is an FDA-approved thromboprophylactic method. Thrombus pathogenesis is considered to depend on factors related to components of the vessel wall, the velocity of blood, and blood consistency-collectively known as, the Virchow's triad.
Objective:
The testimony supporting the thromboprophylactic effects of the EMS is reviewed. An emphasis is placed on the fact that, EMS has demonstrated, in certain circumstances, an efficacy rate that cannot be fully explained by the Virchow's triad; also that, in reviewing relevant evidence and the theorized pathophysiological mechanisms, several findings collectively point to a potentially missed point. Remarkably, venous thromboembolic disease (VTE) is extremely more common in the lower versus the upper extremities even when the blood velocities equalize; EMS had synergistic effects with intermittent compressive devices, despite their presumed identical mechanism of action; sleep is not thrombogenic; non-peroperative EMS is meaningful only if applied ≥5 times daily; neural insult increases VTEs more than the degree expected by the hypomobility-related blood stasis; etc. These phenomena infer the presence of a 4th thrombogenetic factor: neural supply to the veins provides direct antithrombic effects, by inducing periodic vessel diameter changes and/or by neuro-humoral, chemically acting factors. EMS may stimulate or substitute the 4th factor. This evidence-based hypothesis is analyzed.
Conclusion:
A novel pathophysiologic mechanism of thrombogenesis is supported; and, based on this, the role of EMS in thromboprophylaxis is expanded. Exploration of this mechanism may provide new targets for intervention.
