When high blood pressure was induced in young mice, they had bone loss and osteoporosis-related bone damage comparable to older mice, according to new research presented today at the American Heart Association’s Hypertension Scientific Sessions 2022 conference, held Sept. 7-10, 2022, in San Diego. The meeting is the premier scientific exchange focused on recent advances in basic and clinical research on high blood pressure and its relationship to cardiac and kidney disease, stroke, obesity and genetics.
High blood pressure and osteoporosis are prevalent diseases, and people may have both at the same time. In this study, researchers examined inflammation associated with high blood pressure in mice and found it may be connected to osteoporosis.
Researchers tracked the incidence of heart failure over six years in more than 94,000 middle-aged adults in the U.K. Biobank who wore wrist accelerometers to record the amount and intensity of their physical activity over seven days between 2013-2015.
Participants who engaged in 150-300 minutes of moderate physical activity or 75-150 minutes of vigorous physical activity during the week of observation reduced their risk of being hospitalized for or death from heart failure by two-thirds compared to participants who did not engage in the same amounts of moderate or vigorous physical activity during the week.
A six-year analysis of more than 94,000 adults in the U.K. Biobank with no history of heart failure at enrollment has found that engaging in moderate or vigorous physical activity may lower the risk of developing heart failure, according to new research published today in the American Heart Association’s flagship journal Circulation.
The study is one of the first to use objectively measured activity levels to estimate heart failure risk. The results are consistent with previous studies finding that performing 150-300 minutes of moderate exercise or 75-150 minutes of vigorous exercise each week may reduce the incidence of heart attack and stroke.
Taking blood pressure readings from both arms and using the higher reading would more accurately capture who has high blood pressure – and is at increased risk for cardiovascular disease and death – than relying on readings from a single arm, new research suggests.
While current recommendations call for using the higher arm reading, there was previously no evidence in the scientific literature to support the practice, which isn’t routinely followed, according to the study. The findings appeared this week in the American Heart Association journal Hypertension.
“If you are only doing one arm, you can’t know which is the higher-reading arm,” said lead study author Christopher Clark, a clinical senior lecturer in primary care at the University of Exeter Medical School in Devon, England. “And if you don’t catch high blood pressure, you can’t treat it. We can now support the adoption of using the higher reading from both arms.”
Nearly half of U.S. adults have high blood pressure, also known as hypertension. Blood pressure is considered high if the systolic reading – the top number – is 130 mmHg or more, or the diastolic reading – the bottom number – is 80 mmHg or more. High blood pressure is a risk factor for heart disease, heart attacks and strokes.
In a 2019 scientific statement detailing proper blood pressure measurement, the AHA recommended taking readings from both arms during an initial patient visit and using the arm with the higher reading for measurements at subsequent visits. The statement also called for making sure to use the proper cuff size based on the patient’s arm circumference, among other guidance.
Nearly half of all dementia cases in the U.S. may be linked to a dozen modifiable risk factors – most notably high blood pressure, obesity and physical inactivity, according to new research reported by the American Heart Association (AHA). The findings suggest a large portion of dementia cases could be prevented, especially among Black and Hispanic adults, who had the highest percentage of combined risk factors.
“There are things people can do that can raise or lower their individual risk” for dementia, said Mark Lee, a PhD candidate at the University of Minnesota in Minneapolis. He led the study presented Friday at the American Heart Association’s Epidemiology and Prevention, Lifestyle and Cardiometabolic Health conference.
Younger adults (ages 20-40) with high blood pressure had brain changes by midlife (average age 55) that may increase their risk of cognitive decline later in life or over time.
These changes were similar across all races and ethnic groups examined in the study when accounting for the degree of high blood pressure exposure.
The findings suggest health care professionals consider more aggressive high blood pressure treatment for younger adults to prevent brain changes in later life.
High blood pressure among younger adults, ages 20-40 years, appears to be linked to brain changes in midlife (average age 55) that may increase risk for later cognitive decline, according to preliminary research to be presented at the American Stroke Association’s International Stroke Conference 2022, a world premier meeting for researchers and clinicians dedicated to the science of stroke and brain health to be held in person in New Orleans and virtually, Feb. 8-11, 2022.
People with high blood pressure diagnosed before age 55 had smaller brains compared to people who had normal blood pressure, and people who developed high blood pressure in early adulthood had the greatest reduction in brain size, according to a new study analyzing data from the UK Biobank.
People diagnosed with high blood pressure between ages 35 and 44 were 61% more likely to develop dementia during the study’s follow-up period 8-10 years later, compared to individuals who had normal blood pressure during the same years.
The results suggest that initiating efforts to prevent and control blood pressure in early adulthood may help prevent dementia.
Individuals who are diagnosed with high blood pressure at ages 35-44 had smaller brain size and were more likely to develop dementia compared to people who had normal blood pressure, according to new research published today in Hypertension, an American Heart Association journal.
The results raise the possibility that taking steps in young adulthood to control or delay the onset of high blood pressure may reduce the risk of dementia.
A doctor’s presence during a blood pressure reading triggers a “fight or flight” response that can affect the results, say researchers who studied the effect by measuring nerve activity.
“White coat hypertension” – the phenomenon when blood pressure rises in some people who are measured by a medical professional – has been known about for decades. It occurs in about a third of people with high blood pressure.
In a small study published in the American Heart Association Journal Hypertension(link opens in new window), Italian researchers examined the effect’s roots by measuring blood pressure, heart rate and nerve traffic in the skin and muscles with and without a doctor present.
The researchers found a “drastic reduction” in the body’s alarm response when a doctor was not present, said co-lead author Dr. Guido Grassi, professor of internal medicine at the University of Milano-Bicocca in Milan.
A new University of Saskatchewan (USask) study has found that stretching is superior to brisk walking for reducing blood pressure in people with high blood pressure or who are at risk of developing elevated blood pressure levels.
Walking has long been the prescription of choice for physicians trying to help their patients bring down their blood pressure. High blood pressure (hypertension) is a leading risk factor for cardiovascular disease and among the top preventable risk factors affecting overall mortality.
This new finding, published December 18, 2020 in the Journal of Physical Activity and Health, shows that stretching should be part of a well-rounded treatment plan for people wrestling with hypertension.
“Everyone thinks that stretching is just about stretching your muscles,” said kinesiology professor Dr. Phil Chilibeck (PhD), a co-author of the study. “But when you stretch your muscles, you’re also stretching all the blood vessels that feed into the muscle, including all the arteries. If you reduce the stiffness in your arteries, there’s less resistance to blood flow,” he said, noting that resistance to blood flow increases blood pressure.
Memory, concentration and other cognitive functions decline faster among middle-aged and older adults who have high blood pressure than those who do not.
Even seemingly slight blood pressure elevation during middle and older age is linked to a faster decline in cognition.
Controlling high blood pressure slows the speed of cognitive decline.
The length of time, or duration, of high blood pressure does not appear to accelerate cognitive decline.
High blood pressure appears to accelerate a decline in cognitive performance in middle-aged and older adults, according to new research published in Hypertension, an American Heart Association (AHA) journal.
Nearly half of American adults have high blood pressure or hypertension. Having high blood pressure is a risk factor for cognitive decline, which includes such things as memory, verbal fluency, attention and concentration. Blood pressure of 120 mmHg – 129 mmHg systolic (the top number in a reading) or higher is considered elevated. Systolic pressure above 130 mmHg, or diastolic pressure (the bottom number) of 80 mmHg or higher is considered hypertension.
Lockdown due to the COVID-19 pandemic is associated with an increase in high blood pressure among patients admitted to emergency. That’s the finding of a study presented at the 46th Argentine Congress of Cardiology (SAC).
SAC 2020 is a virtual meeting during 19 to 21 November. Faculty from the European Society of Cardiology (ESC) will participate in joint scientific sessions with the Argentine Society of Cardiology as part of the ESC Global Activities program.
“Admission to the emergency department during the mandatory social isolation period was linked with a 37% increase in the odds of having high blood pressure – even after taking into account age, gender, month, day and time of consultation, and whether or not the patient arrived by ambulance,” said study author Dr. Matías Fosco of Favaloro Foundation University Hospital, Buenos Aires.
One in three American adults has hypertension (high blood pressure). And, because hypertension causes few obvious symptoms, many people with high blood pressure don’t even know it. What’s more, only about half of all diagnosed individuals are controlling their blood pressure adequately. This condition is a primary or contributing cause in more than 1,000 deaths each day and costs the nation $48.6 billion each year, according to the Centers for Disease Control and Prevention. But, straightforward lifestyle changes can both prevent and treat this common and devastating “silent killer.”
What is Blood Pressure? “Blood pressure is the force the blood exerts on the walls of the arteries,” says Sondra M. DePalma, DHSc, PA-C, a cardiology PA with PinnacleHealth CardioVascular Institute at UPMC Pinnacle and an author of the American Heart Association’s 2017 Guideline for the Prevention, Detection, Evaluation, and Management of High Blood Pressure in Adults. The top number (the systolic pressure) is the force exerted on the artery wall with each beat (contraction) of the heart. The bottom number (the diastolic pressure) is the force when the heart is at rest (between beats). If readings rise above 120 systolic and 80 diastolic, risks begin to rise. Treatment through lifestyle changes and/or medication is recommended if numbers rise over 130 or over 80. [For more information on blood pressure readings, see Blood Pressure by the Numbers.
Herewith another entry in our arsenal against that destroyer of lives – Alzheimer’s Disease, from the Tufts Health & Nutrition Letter.
Alzheimer’s disease accounts for 60 to 80 percent of the loss of memory and other cognitive abilities collectively known as dementia. There is no known food or diet that can prevent or cure Alzheimer’s dementia, but diet may help delay onset and slow progression.
What sets Alzheimer’s apart from other forms of dementia is the excessive buildup of beta-amyloid protein fragments into plaques, as well as defective tau proteins that form tangles in the brain. These changes lead to the death of the nerve cells responsible for everything from memory to movement. There are currently no known dietary factors that can impact the formation of these plaques and tangles, but diet may act in other ways to influence Alzheimer’s and other forms of dementia.
Younger women are having more heart attacks, says a recent study. Researchers were surprised to find that while the heart attack rate has decreased among older adults, it’s risen among those ages 35-54, especially women. The Atherosclerosis Risk in Communities study reviewed more than 28,000 hospitalizations for heart attacks in four cities.
“This observational study found a trend in young women,” says Virginia Colliver, M.D., cardiologist with Johns Hopkins Community Physicians-Heart Care in Bethesda, Maryland. “But the research doesn’t provide insight into why the uptick in heart attacks is happening to younger people. I suspect it has to do with more people having risk factors for heart disease at an earlier age.”
Heart Attack Risk Factors for Women
There are several factors that increase your chance of developing heart disease. Almost 50% of all Americans have at least one of three major risk factors for the condition: Continue reading →
Blood pressure is like what Mark Twain said about the weather, “Everybody talks about it, but nobody does anything about it.” Well almost. I have found that blood pressure is one of those subjects that is widely and wildly misunderstood. I used to think it was like grey hair on old people. Everybody has it. I was dead wrong.
Few assumptions are more dangerous than this one: If you have high blood pressure, you know it.
Doctors refer to high blood pressure, or hypertension, as a silent killer because it rarely produces warning signs.
“When symptoms do occur, such as headache, nosebleeds or blurry vision, high blood pressure may have already reached severe and possibly life-threatening levels,” says Daniel Pohlman, MD, a primary care doctor at Rush University Medical Center. Continue reading →
Significant reductions in the risk of mild cognitive impairment (MCI)*, and the combination of MCI and dementia**, have been shown for the first time through aggressive lowering of systolic blood pressure in new research results from the federally-funded SPRINT MIND Study reported at the Alzheimer’s Association International Conference (AAIC) in Chicago.
“This is the first randomized clinical trial to demonstrate a reduction in new cases of MCI alone and the combined risk of MCI plus all-cause dementia,” said Jeff D. Williamson, MD, MHS, Professor of Internal Medicine and Epidemiology and Chief, Section on Gerontology and Geriatric Medicine at Wake Forest School of Medicine. Williamson reported these results at AAIC 2018.
The results of this large-scale, long-term clinical trial provide the strongest evidence to date about reducing risk of MCI and dementia through the treatment of high blood pressure, which is one of the leading causes of cardiovascular disease worldwide.
“This study shows more conclusively than ever before that there are things you can do — especially regarding cardiovascular disease risk factors — to reduce your risk of MCI and dementia,” said Maria C. Carrillo, PhD, Alzheimer’s Association Chief Science Officer. “To reduce new cases of MCI and dementia globally we must do everything we can — as professionals and individuals — to reduce blood pressure to the levels indicated in this study, which we know is beneficial to cardiovascular risk.”
