Aging, Heart Rate Variability and Metabolic Impact of Obesity

Abstract: The relationship between aging and changes in heart rate variability (HRV) could depend on the metabolic profile of obese people, i.e. metabolically healthy obese (MHO) and metabolically unhealthy obese (MUO). We aimed to determine the age at which obesity related autonomic dysfunction becomes significant and whether it decreases differently according to metabolic profile. We analyzed HRV in 99 adults using Wildman's criteria for metabolic profile and 5-minute HRV for autonomic nervous system. In MHO, high fre… Show more

“…The α7nAChR is an important mediator of vagal nerve activity, and therefore in the sympathetic/parasympathetic balance of the autonomic nervous system. Many of the high-risk conditions associated with SARS-CoV-2 infection severity/fatality have heightened levels of sympathetic nervous system activity [ 80 , 81 ], which may be contributed by increased KYNA and decreased melatonin that suppresses α7nAChR activity and levels, respectively. The effects of KYNA and decreased melatonin on the α7nAChR may therefore be an aspect of high-risk medical conditions per se, as well as being driven by SARS-CoV-2 infection via tryptophan metabolite regulation.…”

“…It is well established that other factors can directly affect autonomic function, such as obesity [21,22] and levels of physical activity [23,24]. Recent investigations indicate that obesity is associated with poor prognosis for SARS-CoV-2 infection, intensive care hospitalization, and disease progression [25,26].…”

“…У юношей и девушек с избыточной массой тела по сравнению с нормальной массой тела ВРС на 10-минутных интервалах характеризовалась менее выраженной активностью парасимпатического отдела ВНС (LF/HF), что нашло подтверждение в исследованиях других авторов [18,19]. Ряд исследований ВРС у молодых мужчин с избыточной массой тела по сравнению с нормой подтверждал, обнаруженную нами, пониженную парасимпатическую активность уменьшением таких параметров общей ВРС как RMSSD, HF и SDNN [10,20].…”

“…Учитывая многочисленные исследования, подтверждающие дисфункцию вегетативной нервной системы (ВНС) при многих заболеваниях, а также значимость донозологической диагностики вегетативных нарушений у молодых людей с ожирением, представляется актуальным выявление измененных показателей вариабельности ритма сердца (ВРС) в качестве мишеней для превентивных немедикаментозных воздействий, в клинической практике [8,9]. Предупреждение заболеваний, включая адекватную физическую активность (ФА), ассоциированных с метаболическими и системными нарушениями, такими как избыточная масса тела и ожирение, является очевидным показанием к мониторированию ВРС [10,11].…”
