Filter by:The aim of this study is to conduct a definitive trial to assess the efficacy of consuming 1L/day of water rich in potassium to reduce blood pressure in mild to moderately hypertensive adults. The objective is to assess the potential effect of the intervention on reducing systolic blood pressure. This study will comprise of a 4 week, double-blind, parallel randomised controlled trial. Participants will be adults with systolic blood pressure measurements of 130mmHg or greater. The intervention comprises advice to consume bottled water rich in potassium. The comparator will be regular bottled mineral water.This study will recruit 40 people with elevated systolic blood pressure (≥130mmHg) who are not regularly taking antihypertensive medication.
The goal of this study is to test an intervention to prevent high blood pressure among rural, Black adults living in Alabama. Black adults in this region have one of the highest rates of high blood pressure in the US. Eating fruits and vegetables and exercising daily lowers the chance of getting high blood pressure. Many problems get in the way of eating a healthy diet and exercising like a lack of grocery stores with fresh foods, few gyms, little money, lack of transportation, and limited support for keeping healthy habits. One place where many Black adults in rural Alabama meet weekly and feel supported is their church. The investigators will connect with 20 churches in rural Alabama. The investigators plan to hold health fairs to find 27 Black adults from each church with blood pressure that is higher than normal but not high enough to need blood pressure lowering medications. The investigators will randomly select 10 churches to get group health education and tablets to access online cooking shows and exercise classes. Adults in the other 10 churches will get support from a health coach over the telephone to help set and meet diet and physical activity goals as well as the group health education and tablets to access online cooking shows and exercise classes. In this study, the investigators will ask church members to sign up to be a health coach. These 10 churches will also get money to help bring healthy foods and/or physical activity opportunities to their communities. The investigative team will train 2 to 3 of their church members to learn how to coach others to eat more healthy food and be more physically active. This study answers two questions. 1) Will this intervention designed to reduce barriers to a healthy lifestyle lower blood pressure among rural, Black adults? 2) Can churches and participants complete the whole two-year study, and can the intervention be used in other communities in a cost-effective way to improve blood pressure? This project will add to the health equity mission of the American Heart Association by finding out if an intervention using health coaches lowers blood pressure among rural Black adults.
This is a multicenter, randomized, single-blinded clinical trial investigating the effect of dietary management and active aerobic exercise training on reduction of 24-hour ambulatory blood pressure in subjects with prehypertension.
This study intends to further reveal the antihypertensive effect of LRIC and explore its potential mechanisms.
Hypertension is an increasingly important medical and public health issue. The prevalence of hypertension increases with advancing age to the point where more than half of people 60-69 years of age and approximately three-fourths of those 70 years of age and older are affected. The age related rise in SBP is primarily responsible for an increase in both incidence and prevalence of hypertension with increasing age. At present, it is estimated that about 1 billion people worldwide have hypertension (>140/90 mmHg), and this number is expected to increase to 1.56 billion by 2025. Because of the new data on lifetime risk of hypertension and the impressive increase in the risk of cardiovascular complications associated with levels of BP previously considered to be normal, the JNC 7 report has introduced a new classification that includes the term "prehypertension" for those with BPs ranging from 120-139 mmHg systolic and/or 80-89 mmHg diastolic. This new designation is intended to identify those individuals in whom early intervention by adoption of healthy lifestyles could reduce BP, decrease the rate of progression of BP to hypertensive levels with age, or prevent hypertension entirely. Prehypertension is not a disease category. Rather, it is a designation chosen to identify individuals at high risk of developing hypertension, so that both patients and clinicians are alerted to this risk and encouraged to intervene and prevent or delay the disease from developing. Individuals who are pre hypertensive are not candidates for drug therapy based on their level of BP and should be firmly and unambiguously advised to practice lifestyle modification in order to reduce their risk of developing hypertension in the future. The goal for individuals with prehypertension and no compelling indications is to lower BP to normal levels with lifestyle changes, and prevent the progressive rise in BP using the recommended lifestyle modifications.
The investigators are conducting an unblinded pilot randomized control trial of 250 persons living with HIV (PLWH), aged 18-65 years, who receive antiretroviral therapy care at Haitian Group for the Study of Kaposi's Sarcoma and Opportunistic Infections (GHESKIO), are virally suppressed, and have pre-hypertension (systolic blood pressure (SBP) 120-139 or diastolic blood pressure (DBP) 80-89 mmHg) to be randomized to early hypertension (HTN) treatment versus standard of care (SOC). Participants will be recruited from GHESKIO's HIV clinic. Eligible individuals will complete informed consent and be randomized to early HTN treatment vs. SOC. Participants in early HTN treatment will initiate amlodipine immediately versus those in SOC will initiate amlodipine only if they meet the HTN threshold (SBP ≥140 or DBP ≥90 mmHg) during the study period. All participants will be followed for 12 months.
In this RCT, up to 100 adults classified as pre-hypertensive will be randomized to either an artificial intelligence (AI) based lifestyle intervention group or an active control group with a 1 to 1 ratio. Both groups will receive an identical activity tracker (Samsung Galaxy Watch) and BP monitor (Omron Evolv). The AI intervention group will receive automated and personalized lifestyle recommendations based on their lifestyle (e.g. sleep, exercise and diet) and blood pressure (BP) data, involving an automated analytics engine using statistics and machine learning. The active control group will not receive these lifestyle recommendations. The investigators aim to assess objectively the effectiveness of the AI-based personalized lifestyle recommendations on the patients BP.
The aim of the study is to investigate whether physiological, psychological and environmental factors, at an individual level, modify a) adherence, and b) blood pressure response, to a nuts and wholegrains intervention in participants at risk for developing high blood pressure. For 24 weeks, participants will, on a daily basis, monitor their own blood pressure using a wireless blood pressure monitor and respond to short semi-personalised questionnaires using a wrist-worn device, which also measures activity levels. Participants will receive an intervention of wholegrain foods and nuts to substitute into their diets for 8 weeks, between two 8-week observation periods. The length of the study periods will enable repeated measurements to be taken, in order to assess what factors, on an individual level, are associated with fluctuations in the outcomes. This will provide an insight into the types of factors that can help to explain individual fluctuations in adherence and physiological outcomes, such as blood pressure, that are common in nutrition studies. In the future, this should help in tailoring the way the investigators deliver effective individualised interventions, and enable researchers to be better able to consider and control for factors that can affect adherence and response to dietary interventions.
The Wald Outreach Center will partner with Medicine for the Greater Good (MGG) to implement this pilot project called Wald Outreach for Wellness (WOW), a blood pressure outreach wellness intervention in a retail setting.
New data suggests that isometric handgrip training (IHT) might become a novel tool in the treatment of hypertension. The main purpose of this research project is to evaluate the effects of home-based IHT on ambulatory blood pressure in older adults with pre-hypertension and hypertension. Eighty-four older adults with pre-hypertension and hypertension will be randomly distributed to one of three groups: home-based IHT, home-based aerobic exercise training (AET), or attention-control group (CON). Each intervention will have a total duration of 8 weeks. At baseline and after completing the intervention, patients will undergo the following evaluations: 24-hour ambulatory blood pressure, cardiorespiratory fitness, endothelial function, damage and repair, arterial stiffness, inflammatory biomarkers, autonomic function, physical activity levels, dietary intake and quality of life. A qualitative analysis will also be applied to enhance the understanding of the efficacy of this intervention from the patient's perspective.
