High blood pressure, or hypertension, remains a global health concern, contributing to 19% of deaths worldwide. In an international review, biologists highlight the pivotal role of dietary fiber in managing hypertension and reducing cardiovascular disease (CVD) risk, and call for the inclusion of dietary fiber in clinical guidelines for hypertension. The review sheds light on the often-overlooked importance of dietary fiber in blood pressure management. Said Francine Marques, "Dietary fiber has emerged as a crucial yet underappreciated part of hypertension management." "Our comprehensive analysis emphasizes the evidence supporting the effectiveness of dietary fiber in lowering blood pressure and reducing the...

Millions of people with normal blood pressure may be misclassified as having blood pressure that is too high because of improper positioning when measurements are taken, research suggests. Guidelines call for a patient to be seated in a chair with feet flat on the floor, their back supported and the arm wearing the blood pressure cuff supported at heart level. Doing so helps ensure an accurate reading. But many health care professionals take blood pressure measurements while the patient is seated on an examining table, leaving their legs to dangle and their back and arm unsupported. Being misclassified with high...

Measuring blood pressure while patients are standing rather than sitting may improve the accuracy of readings, researchers report. Their findings could lead to significant improvements in early detection of high blood pressure in healthy adults. UTSW researchers measured the blood pressure of 125 healthy patients ages 18-80 with no history of hypertension, previous use of blood pressure medication, or other comorbidities. The statistical analysis used to assess the overall accuracy of each test in diagnosing hypertension revealed that measuring standing blood pressure either on its own or in addition to sitting blood pressure significantly improved diagnostic accuracy. Researchers used several...

An estimated 40% of the global adult population have high blood pressure, or hypertension, which puts people at risk of cardiovascular disease and other dangerous health conditions. Recent studies suggest that probiotics may offer a protective effect. A study adds two new strains to the list of potential antihypertensive probiotics. In experiments on hypertensive mice, treatment with the two probiotics, Bifidobacterium lactis and Lactobacillus rhamnosus, returned blood pressure to normal levels. Previous studies have connected the rising rates of hypertension worldwide to increasing consumption of sugar. It likely boosts blood pressure through many mechanisms—increased insulin resistance or salt retention, for...

Antihypertensive use is associated with a reduced risk for dementia compared with untreated hypertension, according to research. Matthew J. Lennon, M.D. and colleagues examined the associations of hypertension history, antihypertension use, and baseline-measured blood pressure (BP) in late life with dementia in longitudinal, population-based studies of aging adults participating in the Cohort Studies of Memory in an International Consortium group. The analysis included 17 studies with 34,519 community-dwelling older adults (mean age, 72.5 years) and a mean follow-up of 4.3 years. The researchers found that individuals with untreated hypertension had a significantly increased risk for dementia compared with healthy controls...

People who had high blood pressure while lying flat on their backs had a higher risk of heart attack, stroke, heart failure or premature death, according to research. The autonomic nervous system regulates blood pressure in different body positions; however, gravity may cause blood to pool when a person is seated or upright, and the body is sometimes unable to properly regulate blood pressure during lying, seated and standing positions. To examine body position, blood pressure and heart health risk, the researchers examined health data from the longitudinal Atherosclerosis Risk in Communities (ARIC) study. 16% percent of participants who did...

A relatively common health problem—constipation—has been shown to be a risk factor for hypertension and cardiovascular events such as stroke in people over 60. The extensive study of over half a million hospital admissions in Victoria suggests that interventions to address constipation may reduce these risks in elderly patients. The study, led by Professors Grant Drummond and Chris Sobey, looked at 541,172 hospitalized patients over 60 years of age. For each constipation admission, one exact age-matched non-constipated admission was randomly selected from all hospitalizations within two weeks to form the control arm of the study. The researchers found that patients...

Purpose The most important variable risk factor for developing glaucoma is intraocular hypertension. Timely lowering of high intraocular pressure (IOP) significantly lowers the likelihood of developing glaucoma. The aim of this study was to evaluate the effects of the food supplement Mirtogenol® (Mirtoselect® and Pycnogenol®) on IOP and ocular blood flow in a product evaluation study. Methods Thirty-eight asymptomatic subjects with intraocular hypertension were either given Mirtogenol® (20 subjects) or were not treated (18 subjects). The visual acuity, IOP, and ocular blood flow were measured at two, three, and six months. Results After two months of supplementation with Mirtogenol®, the...

Researchers have found that the cause of a common type of high blood pressure originates in a tiny benign nodule, present in one-in-twenty people with hypertension. The nodule produces a hormone, aldosterone, that controls how much salt is in the body. The new discovery is a gene variant in some of these nodules which leads to a vast but intermittent overproduction of the hormone. The variant affects a protein called CADM1 and stops cells in the body from "talking" to each other and saying that it is time to stop making aldosterone. An issue for doctors is the fluctuating release...

Dementia is defined as the loss of cognitive functioning—including thinking, remembering, and reasoning. Currently, the treatment satisfaction for dementia is among the lowest and no drug therapy is available to cure the disease. Cognitive impairment has been linked to the consumption of excess table salt. The involvement of angiotensin II (Ang II)—a hormone that plays a key role in regulating blood pressure and fluid balance—and its receptor "AT1," as well as that of the physiologically important lipid molecule prostaglandin E2 PGE2 and its receptor "EP1" in hypertension and neurotoxicity is well-recognized). To this end, a recent study evaluated the aspects...

Data from the phase III INTERACT3 study demonstrate that a new combination of treatments for stroke due to intracerebral hemorrhage (ICH) significantly improves the chances of surviving without major disability. The INTERACT3 study is the first-ever randomized controlled trial to show a clearly positive outcome for the treatment of ICH. Timely administration of the new treatment protocol—known as a Care Bundle—centered on the rapid control of high blood pressure, led to improved recovery, lower rates of death, and better overall quality of life. Professor Craig Anderson said, "Despite the high rates of ICH and its severity, there are few proven...

Strength training practiced with moderate to vigorous intensity two or three times a week is an effective way to mitigate arterial hypertension (high blood pressure), according to a study. The group analyzed over 21,000 scientific articles and conducted a Cochrane meta-analysis, considered the gold standard for systematic reviews. Cardiovascular diseases are the leading cause of death worldwide, and high blood pressure accounts for 13.8% of deaths from such diseases. Arterial hypertension is diagnosed when systolic blood pressure exceeds 140 millimeters of mercury (mmHg) and/or diastolic pressure exceeds 90 mmHg. "We were interested above all in the volume and intensity found...

A global study of more than 28,000 people has provided the strongest evidence to date that lowering blood pressure in later life can cut the risk of dementia. Dr. Ruth Peters said that in the absence of significant breakthroughs, reducing the risk of developing the disease would be a welcome step forward. "Our study suggests that using readily available treatments to lower blood pressure is currently one of our 'best bets' to tackle this insidious disease." Dr. Peters explained that while many trials have looked at the health benefits of lowering blood pressure, not many included dementia outcomes and even...

BLOOD clots are either dangerous or beneficial depending on how and where they form. According to a case study published in the Lancet, a woman almost lost her leg due to a dangerous blood clot after eating the same fruit daily - how much do you eat? =================================================================== Blood clots often form in response to injury. This is the body's way of stemming bleeding. However, blood clots that form in one or more of the deep veins in the body can spell trouble. This is known as deep vein thrombosis (DVT). According to a chilling case report published in the...

An observational study led by Professor Hiroaki Kanouchi presents the first evidence that eating sunomono—a Japanese vinegared side dish—correlates to lower blood pressure categorization in men. "The benefits of vinegar in a healthy diet are well known. Our research is the first observational study of these benefits; we didn't ask participants to change anything," explained Professor Kanouchi. Previous studies have shown that subjects drinking 30 mL of vinegar daily had lower blood pressure but also lost weight that could account for the lower blood pressure. Sunomono is a traditional side dish made with sliced cucumber or seaweed in rice vinegar,...

People who suffer from ischaemic strokes with no previously diagnosed risk factors have been found to have underlying conditions in the majority of cases, a new study presented today has shown. Overall, the study identified 67.7% of stroke patients with previously undiagnosed major risk factors (UMRF) were found to have one major risk factor. The most common detected vascular risk factor was dyslipidaemia, an imbalance of blood fats such as high cholesterol or raised levels of triglycerides (61.4% of patients). The second most common risk factor was high blood pressure (23.7% of patients), and one in 10 (10.2% of patients)...

Anyone who is taking a diuretic and a renin-angiotensin system (RSA) inhibitor for high blood pressure should be cautious about also taking ibuprofen, according to new research. Diuretics and RSA inhibitors are commonly prescribed together for people with hypertension and are available under various pharmaceutical brand names. Painkillers such as ibuprofen are available over-the-counter in most pharmacies and stores in popular brands. Researchers used computer-simulated drug trials to model the interactions of the three drugs and the impact on the kidney. They found that in people with certain medical profiles, the combination can cause acute kidney injury, which in some...

High blood pressure, or hypertension, is a very common condition. Unfortunately, persistent hypertension can cause long-lasting changes in the structure of vascular smooth muscle cells (the cells making up the walls of blood vessels) through a process called "vascular remodeling." If left unchecked, this restructuring can stiffen arterial walls, which lose their ability to adjust their size appropriately. This, in turn, leads to arteriosclerosis and increases the risk of cerebrovascular disease. Why and how hypertension triggers vascular remodeling is not clear. …In neurons, for example, an excitation in the form of calcium ions (Ca2+) entering the cell through calcium channels...

A team of researchers has found via a three-year trial that the SPYRAL HTN-ON MED renal denervation procedure reduced the blood pressure of volunteers in the trial. High blood pressure, also known as hypertension, is regular elevated blood pressure in the arteries. People with hypertension are at increased risk for strokes, vision loss, dementia and coronary artery disease. For that reason, patients are administered drugs to reduce their blood pressure. Unfortunately, these medications do not work for some patients, and medical scientists seek other ways to lower blood pressure. One technique is called renal denervation, where the nerves in blood...

Former U.S. Rep. Luis Gutierrez was hospitalized this week for “extremely high blood pressure and hypertension,” spouse Soraida Gutierrez said in an emailed statement. “He is under the excellent medical care of doctors who are monitoring the situation closely,” she wrote. He was admitted to a Chicago hospital on Wednesday night. On Friday, a spokesperson said there were no updates. (snip) Gutierrez was among a half-dozen Democrats who introduced articles of impeachment against President Donald Trump in November 2017.
