Filter by:At the moment, the invasive strategy for the infarct-associated coronary artery in patients with ST-segment elevation myocardial infarction (STEMI) necessary to save the myocardium and reduce the size of the necrosis zone remains the leading one. However, despite the high efficiency of providing medical care to patients with acute coronary syndrome (ACS), there remains a high mortality and disability of this group of patients. In this regard, the search for new drug and non-drug strategies for the treatment of patients with ACS is actively continuing. Over the past decade, it has been shown that transcutaneous vagus nerve stimulation (TENS) has a cardioprotective effect both in chronic heart failure and in coronary heart disease, improves cardiac function, prevents reperfusion injury, weakens myocardial remodeling, increases the effectiveness of defibrillation and reduces the size of a heart attack. One of the methods of noninvasive stimulation of the afferent fibers of the vagus nerve is percutaneous electrical stimulation of the auricular branch of the vagus nerve. However, further studies are needed to determine whether stimulation of the tragus can improve the long-term clinical outcome in this cohort of patients.
Transcutaneous electrical stimulation of the auricular vagus nerve (TENS) is a promising method of neuromodulation of the autonomic nervous system in patients with various pathologies. The use of this method requires the determination of a reliable biomarker of successful activation of the vagus nerve using TENS. Currently, most studies focus on the assessment of heart rate variability (HRV) as a marker of the functioning of the autonomic nervous system. Despite the physiological justification of HRV as a biomarker for TENS, the data on the effects of TENS on HRV are ambiguous. In some studies, a significant decrease in the ratio of spectral characteristics (LF/HF) in active TENS was found in comparison with fictitious stimulation (sham), which indicated an increase in the parasympathetic component of HRV. However, other studies have not revealed an increase in HRV.
Adolescent nonsuicidal self-injury (NSSI) and alcohol misuse, alone and especially in combination, portend significant functional impairment in adulthood (e.g., relationship dysfunction, depression, suicidality). Although psychosocial interventions for NSSI and substance use are effective for some, they are also expensive and require highly trained clinicians. Treatment is therefore often unavailable to disadvantaged adolescents and those who live rurally. Thus, lower-cost alternative treatments are needed. We will evaluate the efficacy of noninvasive transcutaneous vagus nerve stimulation (tVNS), an effective treatment for depression, in reducing risk for NSSI and substance misuse among vulnerable adolescents.
