Lowering of blood pressure (BP) in high-risk hypertensive individuals reduces major adverse cardiovascular (CV) and renal events. Diabetic patients with hypertension benefit from BP lowering treatment. The present trial, IPAD-CKD in brief, is a randomized, open-label, parallel-designed, multicenter study involving nearly 5322 patients to be recruited over three years and to be followed up for a median of four years and a half. IPAD-CKD tests the hypothesis that antihypertensive medications in adults with type 2 diabetes, whose seated BP 120-139 mm Hg systolic and below 90 mm Hg diastolic, results in 20% difference in the incidence of major renal events. During follow-up for participants in the intensive group, the sitting systolic pressure should be decreased to below 120 mm Hg, by titration and combination of the double-blind study medications of an angiotensin type-1 receptor blocker Allisartan (240 mg/day), a dihydropyridine calcium-channel blocker (amlodipine 5-10 mg/day), and/or other medications if necessary. For those in the standard group, the sitting systolic pressure should be monitored and controlled below 140 mm Hg.
Energy drinks consumption has varied effects on the hemodynamic, blood glucose levels, brain functions and memory. The use of energy drinks is pervasive and especially young adults consume it often as binge drinking. The negative health effects of excessive use of energy drinks has been reported in the scientific literature. Often energy drinks are consumed to enhance alertness and cognition improvement. In this trial, the investigators intend to compare the effects of a widely available energy drink brand in the country with the usual black tea with 5gm sugar and milk. The aims of this study is: 1. To determine the effect of consumption of energy drinks on hemodynamics parameters. 2. To determine the effect of consumption of energy drinks on short term memory 3. To determine the effect of consumption of energy drinks on vigilance in adults 4. To determine the effect of consumption of energy drinks on blood glucose in adults 5. To analyze the effect of energy drink on perception in adults
Type 2 diabetes mellitus (T2D) is a chronic inflammatory disease that is associated with loss of functional capacity and increased blood pressure. Coupled with this, there is an increased risk of falls and fractures in patients with T2D. On the other hand, conventional training programs for resistance, aerobic or combined exercises are strongly recommended for people with T2D, as they promote a reduction in the glycemic rate and blood pressure, and an improvement in functional capacity. However, little is known about unconventional training programs such as PILATES (dynamic and isometric muscle actions) on functional capacity and cardiovascular adaptations in T2D.
Approximately 12% of the world's population have a have a common C677T polymorphism in the gene encoding the folate metabolising enzyme, methylenetetrahydrofolate reductase (MTHFR). Homozygosity for the polymorphism (TT genotype) appears to result in an increased requirement for the B-vitamins folic acid and riboflavin and more importantly results in an increased risk of developing high blood pressure (BP). Previous work from our Centre has demonstrated significantly higher BP in those with the TT genotype. This work has been conducted in cohorts with premature cardiovascular disease (CVD) and hypertension without overt CVD, but the effect in younger, healthier individuals is unexplored. To date our studies have also focused on BP as the primary outcome, but newer markers of vascular health including central pressure and hemodynamics have emerged as superior prognostic indicators of CVD. The effect of the TT genotype on these measures is thus an important area for investigation and may help us understand the mechanism linking the genotype with BP, which is currently unknown. As adults with the TT genotype appear to have increased requirements for riboflavin and folic acid, and BP in TT adults appears to be riboflavin dependent, the influence of these vitamins on central measures is an area for consideration. Study Design This is an observational study investigating the blood pressure profiles of healthy adults aged 18-65 years, stratified by MTHFR genotype. Apparently healthy adults will be recruited from workplaces and the general community across Northern Ireland and screened for the polymorphism via buccal swab. Those with the TT genotype and a similar number of non-TT (i.e. CC/CT) genotype individuals will be contacted and asked to come to attend a one-off appointment. Brachial BP will be assessed by an electronic BP monitor, central BP and central haemodynamics (augmentation index, augmentation pressure and pulse wave velocity) will be assessed by SphygmoCor XCEL. In addition, anthropometric measurements, health and lifestyle information and a blood sample will be obtained. Data will be statistically analysed using SPSS software to if determine differences between gentoype groups exist.
Ephedrine is commonly clinically vasoactive drugs, which can constrict blood vessels and increase blood pressure. Ephedrine can not only stimulate α receptors, but also β receptors, that's to say, it can increase heart rate, stroke volume, and cardiac output, but it also can decrease the level of systemic vascular resistance. This research aims to observe the short-term vasodilator effect of diffierent doses of ephedrine used in elderly patients under general anesthesia in clinical practice, and analyze the main reasons for this phenomenon and take preventive actions to minimize the possibility of further lowering of blood pressure to provide references for clinical rational use of drugs.
Some patients participating in the underlying GUARDIAN trial (NCT04884802) will be additionally randomized to norepinephrine or phenylephrine infusion to maintain the designated target intraoperative mean arterial pressure.
The purpose of this study is to examine the hypothesize that 4 weeks of sympathetic nerve activity (SNA) inhibition (oral clonidine) will cause a significant reduction in circulating blood concentrations and endothelial cell expression of inflammatory markers (e.g., TNF-α, IL-6). Our study is a prospective study using a randomized, double-blinded design to test 4 weeks of SNA blockade (oral clonidine) compared with a BP-lowering control condition (diuretic, hydrochlorothiazide) or a placebo.
The purpose of this study is to evaluate the accuracy of the YuWell YE660D oscillometric upper-arm blood pressure monitor for clinic and home in general population according to the Association for the Advancement of Medical Instrumentation/European Society of Hypertension/International Organization for Standardization (AAMI/ESH/ISO) Universal Standard (ISO 81060-2:2018).
During major surgery, it is recommended to monitor invasive arterial blood pressure and cardiac output (CO) during hemodynamic interventions (fluid challenge or vasopressors). Esophageal Doppler is currently considered as the reference method for monitoring cardiac output in the operating room. The PRAM method (pressure recording analytical method) with the MostCareUp monitor (Vytech, Padova, Italy) and the LTIA method (long time interval analysis) allow cardiac output estimation derived from non-calibrated arterial pressure waveform analysis. Few studies have looked at relative changes in cardiac output during hemodynamic intervention with these two methods. The aim of this study is to compare the relative changes in cardiac output during hemodynamic interventions as measured using PRAM and LTIA methods, compared to esophageal Doppler.
