Filter by:Intradialytic hypertension (IDH) is a well-recognized and established complication of hemodialysis that affects an estimated 10-15% of the dialysis population and is associated with an increased risk for cardiovascular adverse events and mortality. The major pathogenic mechanisms include volume and sodium overload, endothelial dysfunction and enhanced vasoconstriction potentially through the renin-angiotensin-aldosterone system (RAAS) and sympathetic nervous system (SNS) activation. Preliminary uncontrolled studies have demonstrated that in order to achieve proper control of blood pressure (BP) in patients with IDH, volume control with achievement of dry weight, as well as the minimization of sodium load through alteration of dialysate sodium may improve BP. To this day, 3 studies have attempted to evaluate the effect of low dialysate sodium on BP levels in patients with IDH; one study that included 16 patients, compared the effect of low (5 milliequivalent/litre (mEq/L) lower than serum sodium) versus high (5 mEq/L higher than serum sodium) dialysate sodium concentration on BP levels only during the dialysis session; another study examined the effect of low (136 mEq/L) compared to standard (140 mEq/L) sodium dialysate, again, only on peridialytic and intradialytic BP; and only one randomized cross-over study used 24h ABPM to assess the effect of individualized isonatremic vs hyponatremic vs standard dialysate sodium. Hence, the aim of this study is to examine the effect of low (137mEq/L) vs standard (140mEq/L) dialysate sodium on 48h ambulatory blood pressure monitoring (ABPM) in patients with IDH, using appropriate design of randomized crossover study. In addition this is the first study examining the effect of low dialysate sodium on ambulatory central BP, arterial stiffness indices and BP variability in patients with IDH.
This study aims to explore the efficacy and safety of remote ischemia adaptation for the treatment of resistant hypertension.
The sodium found in salt is a powerful cause of high blood pressure, and most sodium ingested by humans is from their diet. High blood pressure is known to cause heart attacks and strokes, so various public health programs have attempted to find ways for people to reduce their salt intake to avoid these complications. These programs, however, have proven challenging, as asking people to alter their food preparation practices is often met with resistance. As such, we wish to test the blood pressure-lowering effects of low sodium salt substitute (LSSS), a salt substance in which a third of the compound by weight is composed of potassium (which does not increase blood pressure) rather than sodium. Additionally, the best way of supplying LSSS to people is yet unknown. We thus propose to study the effectiveness of an LSSS product by directly providing it via community health workers in 309 households in rural Bangladesh.

Study design: Investigator initiated, single center The study is aimed 1) To investigate the blood pressure (BP) change to renal nerve stimulation(RNS), and subsequently perform a renal denervation(RDN) procedure 1) to verify the cutoff value (RNS-induced systolic BP change <20 mmHg in post-RDN patients) could be a useful clinical endpoint in RDN therapy, and test the hypothesis that intense RDN could improve the efficacy of RDN.
Spinal pain or misalignment is a very common disorder affecting a significant number of populations resulting in substantial disability and economic burden. Various manual therapeutic techniques such as spinal manipulations and mobilizations can be used to treat and manage pain and movement dysfunctions such as spinal malalignments and associated complications. These manual therapeutic techniques can affect the cardiovascular parameters . -
In this study the investigators target three common and comorbid illnesses among older adults namely nocturia or waking at night to void, poor sleep and hypertension. The aim of this proposal is to test behavioral sleep intervention to improve sleep and nocturia vs switching the time of antihypertensive administration to improve nighttime and in turn daytime blood pressure control.
The investigators intend to evalute the value of radiomics signature of pulmonary vessels from chest computed tomography (CT) for dianosis and prognosis of pulmonary arterial hypertension.
The optimal antihypertensive treatment strategy in young and middle-aged hypertensive adults remains undefined. Clonidine controlled-release patches administered once a week might have the advantage of convenience. ECLIPSE trial is intended to explore the effect and patient tolerability of clonidine controlled-release patches (one patch per week for a total of 8 weeks) in the treatment of hypertension in young and middle-aged adults, compared with long-acting antihypertensive drug amlodipine. Clonidine patch was demonstrated ameliorating the early withdrawal symptoms during smoking cessation. This trial is also intended to observe its effect on smoking cessation in young and middle-aged male smokers.
The investigators hypothesize that communities in which religious leaders are provided with education about blood pressure and how to measure blood pressure will have lower overall average blood pressures than communities in which religious leaders do not receive education about blood pressure.
