High blood pressure takes big toll on small filtering units of the kidney

2008-09-19 13:35

Take a kidney out of the body and it still knows how to filter toxins from the blood. But all bets are off in the face of high blood pressure.

"How does the kidney know how to do it and why does it break in hypertension?" says Dr. Edward W. Inscho, physiologist in the Medical College of Georgia Schools of Medicine and Graduate Studies.


Audio Relaxation Program May Lower Blood Pressure

2008-09-19 09:15

An audio relaxation program lowered blood pressure more than a Mozart sonata in a group of elderly people with high blood pressure, researchers reported at the American Heart Association’s 62nd Annual Fall Conference of the Council for High Blood Pressure Research.

In a study of 41 elderly participants at three retirement facilities:

• Twenty participants listened three times a week for four months to a 12-minute audio-guided relaxation training program (ATP) with background sounds of ocean waves and a calming voice.


Researchers Use Honeybee Venom To Study Hypertension

Researchers at the University of Pennsylvania School of Medicine have modified honeybee venom so that it can be used as a tool to study the inner workings of ion channels that control heart rate and the recycling of salt in kidneys. In general, ion channels selectively allow the passage of small ions such as sodium, potassium, or calcium into and out of the cell.


NYC Delivers Free Blood Pressure Machines To Pharmacies

High blood pressure is a time bomb that can trigger a deadly heart attack or stroke without warning. And because the condition often has no symptoms, getting checked is the only way to know whether you have it and if it is under control. To make checking your blood pressure easier and more accessible, the Health Department is teaming up with pharmacies in East and Central Harlem, the South Bronx, and North and Central Brooklyn to provide blood pressure monitoring machines at no cost.


Exercise Can Lead To Drop In Blood Pressure

Working up a sweat could be the most important lifestyle change people with high blood pressure — or hypertension — can make in their daily lives. Yet, although patients who receive exercise counseling seem to listen, few physicians actually take the time to talk about physical activity with their patients, a large nationwide study finds.

Just over one-third of people with a hypertension diagnosis said a clinician told them to increase their physical activity to help lower their blood pressure.

They listened.


Children With High Blood Pressure Can Benefit From 24-Hour Monitoring

2008-08-06 10:55

The American Heart Association now recommends 24-hour blood pressure monitoring for certain children and adolescents suspected of having high blood pressure or a condition that causes unreliable readings at the doctor’s office.

The statement, published in Hypertension: Journal of the American Heart Association, is expert-opinion driven and not evidence-based. That’s because studies relating 24-hour monitoring in children to hard outcomes like heart attack and stroke are not yet available.


Exposure To Bad Air Raises Blood Pressure

The air people breathe while walking in the park, working in the garden or shopping downtown may be unhealthy enough to seriously spike their blood pressure, a new study suggests.

Cardiovascular researchers at The Ohio State University Medical Center are the first to report a direct link between air pollution and its impact on high blood pressure, or hypertension. If the results from these animal studies hold up, this could be important for human health.


High Levels Of Urinary Albumin In Normal Range Predict Hypertension

2008-07-05 09:05

Healthy individuals with higher levels of albumin excretion, even levels considered normal, are at increased risk of developing hypertension (high blood pressure).

Because kidneys normally prevent large molecules such as albumin from being excreted in the urine, high levels of urinary albumin excretion— called albuminuria—can be an indicator of kidney damage. Albuminuria may also reflect dysfunction of endothelial cells throughout the body, which in turn may be a precursor to hypertension.


Men, Especially Blacks, More Likely To Miss Own Hypertension

2008-07-03 08:52

A new study suggests that American men are much more likely than women are to be unaware that they suffer from high blood pressure. African-American men with the condition are at the highest risk, with only one in seven both aware of their illness and able to control it through medication.
