Filter by:This is a multicenter, open-label, parallel-group, randomized controlled trial that will be conducted across mainland China. This trial will test the primary hypothesis of whether an intensive treatment strategy (a systolic blood pressure target of <120 mmHg) is more effective than a standard treatment strategy (a systolic blood pressure target of <140 mmHg) in reducing the risk of major cardiovascular disease (non-fatal stroke, non-fatal myocardial infarction, treated or hospitalized heart failure, and cardiovascular deaths) over a follow-up period of up to 5 years among patients with a history of diabetes and elevated systolic blood pressure. The secondary hypotheses are to compare the intensive blood pressure treatment strategy with the standard treatment strategy on dementia and cognitive function, individual components of the primary hypothesis, all-cause mortality, kidney outcomes, quality of life, and injurious falls, et al.
[Development of diagnosis algorism for paroxysmal arrhythmia using ultra-thin resistive membrane: a pilot study] Comparison of blood pressure via tunable crack sensor and invasive pressure wire
This double-blind, placebo-controlled randomized clinical trial will test whether a magnesium glycinate supplement (480 mg/day) taken for 12 weeks lowers blood pressure.
The study will examine urinary sodium excretion induced by psychological stress and its diurnal pattern as a novel biological mechanism that may underlie an abnormal diurnal pattern of blood pressure. The study will test the hypotheses that lower stress-induced sodium excretion is associated with an abnormal diurnal pattern of sodium excretion, and that an abnormal diurnal pattern of sodium excretion is associated with an abnormal diurnal pattern of blood pressure. Primary Aim 1: To examine the association between urinary sodium excretion after provoked psychological stress and the diurnal pattern of sodium excretion. Primary Aim 2: To examine the association between the diurnal pattern of sodium excretion and the diurnal pattern of BP. Secondary Aim: To examine whether the association between urinary sodium excretion after provoked stress and the diurnal pattern of sodium excretion is modified by ecological momentary levels of perceived stress, experienced during the daytime period. Exploratory Aim: To determine the socio-demographic, behavioral, and psychological traits, chronic stress, and biological stress-related factors that are associated with lower stress-induced sodium excretion. Identification of these factors will help determine who is at risk for having a differential sodium excretion response to psychological stress.
The European Association for the Study of Diabetes (EASD) guidelines have not made any specific recommendations regarding the Dietary Approaches to Stop Hypertension (DASH) diet, a dietary pattern that emphasizes fruits and vegetables, low-fat or non-fat dairy, limiting saturated fat intake and usually also recommends limiting sodium intake. To update the recommendations, the Diabetes and Nutrition Study Group (DNSG) of the EASD commissioned an umbrella review of systematic reviews and meta-analyses using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach to summarize the available evidence from recent systematic reviews and meta-analyses of prospective cohort studies and randomized and non-randomized controlled trials of the relationship between the DASH dietary pattern and cardiometabolic risk.
This prospective cohort study will investigate the physiology and progression of autonomous aldosterone secretion.
A monocentric, non-randomized, prospective study in which each patient is his/her own control. The study investigates 2 methods of blood pressure measurement, within the first 24 hours after reperfusion, i) Continuous measurement of blood pressure with the Clearsight device (Edwards) and ii) intermittent blood pressure measurements with cuff.
The present study conducted a meta-analysis of 22 randomly controlled trials to assess the effects of soluble fiber intake on blood pressure in human subjects. Using the Cochrane Handbook for Systematic Reviews of Intervention, a systematic review and meta-analysis was conducted. Information regarding study methods, characteristics, mean BP and standard deviations were extracted The data from each study were pooled using a random effects model to estimate the effects of soluble fiber consumption on blood pressure.
This project will develop and evaluate an interactive blood pressure self-management program for adults with prehypertension. The program will target blood pressure self-monitoring and the five proven lifestyle modifications recommended by JNC-7: weight reduction, the Dietary Approaches to Stop Hypertension (DASH) diet, sodium reduction, physical activity, and alcohol consumption. The multi-modal program uses a combination of brief motivational health coaching, periodic engagement emails, and a robust interactive website to motivate people to take charge of their blood pressure management before they require medication. All program components were designed to conform to the underlying principles of motivational interviewing. Key program components include the use of email and Web-based social networking, personal stories, and a brief motivational coaching session to engage participants and encourage intrinsically motivated behavior changes. Self-assessment and tracking tools are combined with educational content to help participants align their daily lifestyle choices with their personal goals. The Phase I prototype program promoted moderate physical activity and eating fruits and vegetables as part of the DASH diet. Results from the within-group (n = 39) evaluation showed moderate-to-large effect sizes for pre-to-post change in motivation, preparation behavior, self-efficacy, attitudes, and knowledge, and a small significant increase in physical activity. Participants gave the online program high ratings on satisfaction and usability, and reported improvements in confidence, readiness, clarity, change strategies, and interest in visiting the Website as a result of the coaching session. The fully developed Phase II product will be evaluated in a large randomized trial (N = 450) with a 3-month intensive intervention, a 3-month maintenance intervention, and a 3-month follow-up period. The Phase II trial is expected to show reductions in blood pressure and improvements in JNC-recommended health behaviors. These changes in the outcome measures are expected to be mediated by changes in knowledge, attitudes, self-efficacy, behavioral intention, motivation, and patient activation.
High saturated fat acids diets are associated with elevated blood pressure which is associated with cardiovascular morbidity and mortality. For this reason, a change of diet is recommended to manage blood pressure and prevent cardiovascular complications. To achieve this nutritional goal, a high-carbohydrate diet or high-monounsaturated fat diet can be advised in the replacement of a saturated fat diet. Previous meta-analysis of Garg (1998) cited randomized articles with inconsistent blood pressure lowering after consumption of a high-monounsaturated-fat diet compared with a high-carbohydrate diet only in type 2 diabetes patients. Moreover, another meta-analysis of Shah et al. (2007) showed slightly high blood pressure on diets rich in carbohydrates than diets rich in cis-monounsaturated fat after randomized and nonrandomized articles. For this reason, a new meta-analysis of a randomized clinical trial will be performed to clarify the effects of high-carbohydrate or high-monounsaturated fat diets on blood pressure. Results from this meta-analysis will help health professionals take important decisions on patient diet and minimize cardiovascular morbidity and mortality.
