Aldosterone is a steroid hormone made by the adrenal cortex (the outer layer of the adrenal gland). It helps control the balance of water and salts in the kidney by keeping sodium in and releasing potassium from the body. Too much aldosterone can cause high blood pressure and a build-up of fluid in body tissues. Aldosterone is a type of mineralocorticoid hormone.
A low-salt diet may be more beneficial in lowering blood pressure in females than males, report scientists who found that while actual salt retention isn't higher in females, there is still an effect that drives pressure up.
Drugs that inhibit a hormone that constricts blood vessels also help improve sodium excretion in blacks who hold onto too much sodium in the face of stress, investigators report.
Resistant hypertension affects 12 percent to15 percent of patients treated for high blood pressure according to a new scientific statement from the American Heart Association.
Physician researchers with The Ohio State University College of Medicine at the Wexner Medical Center say increased levels of the hormone aldosterone, already associated with hypertension, can play a significant role in the development of diabetes, particularly among certain racial groups.
Data from the TRANSITION study presented today at the European Society of Cardiology Congress in Munich, Germany has shown that Entresto® can be initiated early and safely in a wide range of heart failure patients with reduced ejection fraction who have been stabilized after hospitalization due to an acute heart failure episode.
Why does drinking alcohol or consuming sugar make us thirsty? An international study of mice in Texas and humans in Europe reveals an unexpected anti-dehydration mechanism.
Obese, premenopausal women can lose the innate protection from cardiovascular disease that their youth and estrogen are believed to afford, and scientists want to know how.
More than a billion people worldwide suffer from high blood pressure (hypertension). Prolonged hypertension damages blood vessels, which can result in damage to the heart, the kidneys, and the brain. Possible consequences include heart attack, kidney failure, and stroke.
In just four months, high-doses of vitamin D reduce arterial stiffness in young, overweight/obese, vitamin-deficient, but otherwise still healthy African-Americans, researchers say.
A new study led by researchers at Sanford Burnham Prebys Medical Discovery Institute, in collaboration with researchers at Eunice Kennedy Shriver National Institute of Child Health and Human Development, part of the National Institutes of Health, identifies a mechanism that explains the development of hyperaldosteronism.
Researchers at Texas Tech University Health Sciences Center investigated a pump-induced disease and defined the molecular mechanism that triggers it. The study, "On the effect of hyperaldosteronism-inducing mutations in Na/K pumps," was published in the October issue of the Journal of General Physiology.
One in three American adults suffers from high blood pressure, or hypertension. The disease can be passed down in families, and certain lifestyle factors such as smoking, high-sodium diets, and stress can increase the risk.
While the average American's high-salt diet has been linked to high blood pressure and cardiovascular disease, the truth is we couldn't live without this once scarce mineral.
Using two simple blood tests, Western University researchers were able to drastically improve treatment for resistant hypertension across three sites in Nigeria, Kenya and South Africa.
Research led by scientists at the University of Birmingham has revealed a new cause of high blood pressure which could lead to major changes in managing the disease.
A new Scientific Statement issued by the Endocrine Society advises healthcare providers on ways to spot hormonal causes of high blood pressure that can be cured with surgery or treated effectively with medication.
Lack of exercise and excessive weight are strongly associated with a type of heart failure that has a particularly poor prognosis, UT Southwestern Medical Center researchers determined in an analysis of data from three large studies.
Over 93 percent of heart attack patients are receiving stents within the guideline-recommended threshold of 90 minutes after arriving at the hospital, with the median time to stenting only 59 minutes, according to a broad report on trends in heart disease care from the American College of Cardiology's National Cardiovascular Data Registry published in the Journal of the American College of Cardiology.
The academic partners in the VerICiguaT GlObal Study in Subjects with Heart Failure with Reduced EjectIon FrAction are pleased to announce that patient enrollment has begun.
Among U.S. adults with diabetes from 1988 to 2014, the overall prevalence of diabetic kidney disease did not change significantly, while the prevalence of albuminuria declined and the prevalence of reduced estimated glomerular filtration rate increased, according to a study appearing in the August 9 issue of JAMA.
