Filter by:The purpose of this study is to better understand the effects of nicotinamide riboside supplement in overall cardiovascular health in healthy adults.
The aim of this study is to evaluate the diagnostic performance of Withings bathroom scales WBS08 and WBS12 to measure PWV (Pulse Wave Velocity).
Existing data points to relevant beneficial effects of respiratory exercises on cardiovascular health, with special regards to decreases on arterial pressure and improves on autonomic and vascular profiles, though mechanistics of such results have not yet been cleared. Among the available ways to perform respiratory exercises, there is the highly recommended Inspiratory Muscle Training (IMT) and slow breathing exercises like Yoga pranayamas. Lately, the development of new technologies has allowed the use of Apps to perform respiratory exercises. This study will be take the just developed CardioBreath®App to validate it as a tool to perform respiratory exercises. Therefore, it will be compared to IMT on cardiac vagal modulation and pulse wave velocity on normotensive post menopause women.
Uncontrolled blood pressure represents the main factor in the development of target organ lesions and, consequently, cardiovascular events, which are the leading cause of morbidity and mortality worldwide. In most cases resistant hypertension is preceded by target organ lesions, and is strongly influenced by risk factors or associated diseases. To control this disease requires an adequate and intense therapeutic approach that includes lifestyle changes and the use of several antihypertensive drugs. However, the results are not always satisfactory despite intensive treatment. Of the different pathophysiological mechanisms involved in the pathogenesis of resistant hypertension (RH), two, sympathetic overstimulation and therapies that block the sympathetic system, have been widely studied. But, these approaches are invasive and expensive. Another possible approach is by transcutaneous electrical nerve stimulation (TENS), a non-invasive method that modulates activity by inhibiting primary afferent pathways using low-frequency transcutaneous electrical stimulation. Some studies have shown that TENS reduces blood pressure in patients with hypertension. The current study will evaluate the effect of applying TENS in the cervicothoracic region of subjects with resistant hypertension, seeking to develop a new low cost and readily available therapy to treat this group of hypertensive individuals.
