Non-pharmacological methods of treatment and prevention of vasovagal syncope

Journal of Education, Health and Sport, 2018
Fainting is a transient loss of consciousness resulting from a momentary ischemia of the central nervous system. One type of syncope is vasovagal syncope, otherwise known as reflex or neurogenic syncope. The consequence of fainting may be a fallen injury.

Phenotype characterization of heart failure with preserved ejection fraction in medical device and surgical trials

ESC Heart Failure, Volume 12, Issue 6, Page 3878-3898, December 2025.
This systematic review identified 24 clinical trials of medical device and surgical interventions for HFpEF, with 16 demonstrating at least safety and feasibility, but little evidence of long‐term benefit. Phenotype‐based responses suggest that certain interventions may benefit specific HFpEF subgroups, yet most trials suffered from heterogeneous ...

Multistructure index characterization of heart rate and systolic blood pressure reveals precursory signs of syncope

Scientific Reports, 2017
Recurrent syncope — abrupt loss of consciousness — can have a serious impact on patients’ quality of life, comparable with chronic illnesses. Vasovagal syncope (VVS) is a specific reflex syncope, in which an inappropriate reaction of the autonomic ...
