Hypertension (High Blood Pressure) News and Research

RSS

Hypertension (or high blood pressure) is a condition where the pressure of the blood flowing through the arteries of the body is higher than it should be. Much like the pressure of the air in a tire, if the pressure of the blood is too high it can damage the arteries and organs of the body. Just like the tire, if the pressure suddenly becomes very high, catastrophic events can happen. Similarly, if the pressure remains somewhat elevated for a long enough period of time, premature wear and failure can occur.

Hypertension has its worst effects on the heart, kidneys, eyes, and brain. High blood pressure is a risk factor for heart attack, stroke, kidney failure, hemorrhages of the retina of the eye, and generalized atherosclerosis (hardening of the arteries all over the body).

DASH diet to lower blood pressure also reduces women's risk of heart failure

The DASH diet was initially developed to help patients lower their blood pressure, but a large study led by investigators at Beth Israel Deaconess Medical Center (BIDMC) demonstrates that women who followed the diet also significantly reduced their risk of developing heart failure.

New evidence of how high glucose damages blood vessels could lead to new diabetes treatments

New evidence of how the elevated glucose levels that occur in diabetes damage blood vessels may lead to novel strategies for blocking the destruction, Medical College of Georgia researchers say.

High-caloric exercise reduces risks in heart patients the most

An exercise program that burns a lot of calories reduced cardiac risk factors better than standard cardiac rehabilitation in overweight coronary patients, researchers report in Circulation: Journal of the American Heart Association.

New genetic clues to treatment of hypertension

An international research team has identified a number of unsuspected genetic variants associated with systolic blood pressure (SBP), diastolic blood pressure (DBP), and hypertension (high blood pressure), suggesting potential avenues of investigation for the prevention or treatment of hypertension.

Discovery of major new treatment target in diseased arteries

Removing a single protein prevents early damage in blood vessels from triggering a later-stage, frequently lethal complication of atherosclerosis, according to research published online today in the journal Nature Medicine. By eliminating the gene for a signaling protein called cyclophilin A (CypA) from a strain of mice, researchers were able to provide complete protection against abdominal aortic aneurysm (AAA).

Research confirms benefits of mobile health screening program to help diagnose at-risk populations

Results presented today at the American Society of Hypertension's Twenty Fourth Annual Scientific Meeting (ASH 2009) reveal that hypertension is still disproportionally prevalent in African-American women living in Boston’s inner city neighborhoods, despite recent improvements in diagnostic and treatment options.

Low blood pressure may increase risk of heart attack and stroke

Data from the Treating to New Targets (TNT) trial presented today at the American Society of Hypertension's Twenty Fourth Annual Scientific Meeting (ASH 2009) show that low blood pressure levels may lead to increased risk of cardiovascular events, including heart attack and stroke. These data supplement previous findings from the TNT trial of atorvastatin showing aggressive LDL cholesterol-lowering reduced cardiovascular events.

Significantly increased mortality rate in elderly patients with nocturia

Patients suffering from nocturia, the need to urinate at least twice during the night, may have a significantly increased risk for mortality.

Blacks, Hispanics more concerned about Alzheimer's than whites, but less informed

Blacks and Hispanics are more concerned than whites about Alzheimer's disease but less knowledgeable about means to delay its onset, according to a new survey, United Press International reports.

New method a dream come true for sleep apnea patients

Researchers from the University of Sydney have found the first hard evidence that the special masks doctors prescribe to patients with sleep apnea - a disorder that can cause interrupted breathing leading to choking and even death while asleep - actually work.

Kids with high blood pressure more likely to have learning/attention problems

Children who have high blood pressure are more likely to have learning disabilities and attention deficit hyperactivity disorder (ADHD) than children who are not hypertensive. They are also more likely to have a higher body mass index (BMI), an indicator of body fat.

Obstructive sleep apnea increases risk of heart and vascular disease

Obstructive sleep apnea, or periodic interruptions in breathing throughout the night, thickens sufferers' blood vessels. Moreover, it increases the risk of several forms of heart and vascular disease.

New light shed on salt-sensitive hypertension

A high salt intake has been implicated in cardiovascular disease risk for 5000 years. But salt-sensitive hypertension still remains an enigma.

FDA extends action date for inhaled Treprostinil (Tyvaso) NDA by three months

United Therapeutics Corporation has announced that the U.S. Food and Drug Administration (FDA) will require additional time to complete its review of the New Drug Application (NDA) for Tyvaso (inhaled treprostinil).

Out-of-pocket costs reduce patients' willingness to start treatment for their chronic illnesses

Patients newly diagnosed with hypertension, diabetes or high cholesterol are significantly more likely to delay initiating recommended drug treatment if they face higher co-payments for medications, according to a new RAND Corporation study.

Smoking, hypertension and BMI are the leading preventable risk factors for premature mortality in the U.S.

The researchers found that smoking is responsible for 467,000 premature deaths each year, high blood pressure for 395,000, and being overweight for 216,000. The effects of smoking work out to be about one in five deaths in American adults, while high blood pressure is responsible for one in six deaths.

Increased mortality linked to frequent nightime urination

Patients suffering from nocturia, the need to urinate at least twice during the night, may have a significantly increased risk for mortality.

Researchers discover key enzyme in the development of cardiac insufficiency

This enzyme is involved in the accumulation of fibrous tissues in the hearts of patients with chronic cardiac diseases and deterioration of heart functions.

Black-white differences in avoidable mortality in the United States, 1980-2005

Two-thirds of the difference between death rates among African Americans and Caucasians are now due to causes that could be prevented or cured, according to a new study appearing in the Journal of Epidemiology and Community Health.

High blood pressure, diabetes and increased carotid artery wall thickness means increased risk of stroke

Increased carotid artery wall thickness (CAWT), which can cause heart attack and stroke in many patients, is significantly related to diabetes and hypertension, according to a study performed at A.O.U. in Cagliari Sardegna, Italy (Chairman, Professor Giorgio Mallarini).
