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).

Study examines clinical, kidney morphologic features that predict favorable BP response to renal artery stenting

A retrospective study in the May 2011 issue of the Journal of Vascular Surgery, the official publication of the Society for Vascular Surgery, examines clinical and kidney morphologic features that predict a favorable blood pressure response to renal artery stenting.

Exercise, sex, coffee and even nose blowing may raise risk of stroke: Study

According to researchers in the Netherlands, coffee, sex and nose blowing could increase the risk of a type of stroke. The study on 250 patients identified eight risk factors linked to bleeding on the brain. These factors all increase blood pressure which could result in blood vessels bursting, according to research published in the journal Stroke.

Statins for all over 55: Study

The latest research findings suggest that when assessing the risk of heart problems, offering statins or drugs that lower cholesterol to all over-55s had the same results as testing for cholesterol or blood pressure problems. The authors have also argued it would be simpler and more cost effective.

Increasing prevalence of hypertension boosts growth for blood-pressure monitors in BRIC countries

With a rapidly ageing population and increasing prevalence of hypertension, there is a growing number of people that need to monitor their blood-pressure at home. Whilst the more established home-use digital blood-pressure monitor markets in Western Europe and North America are reaching saturation, the emerging BRIC markets are becoming more aware of lifestyle-related disease prevention and are investing heavily to improve healthcare provisions, driving growth of the blood-pressure monitors market.

Pfizer’s Revatio receives European Commission approval for pediatric treatment of pulmonary arterial hypertension

Pfizer Inc. announced that Revatio (sildenafil citrate) has been approved by the European Commission for the treatment of pediatric patients aged 1 to 17 years old with pulmonary arterial hypertension. Efficacy in terms of improvement of exercise capacity or pulmonary hemodynamics has been shown in primary pulmonary hypertension and pulmonary hypertension associated with congenital heart disease.

Low salt intake may increase risk of cardiovascular events

In a study conducted to examine the health outcomes related to salt intake, as gauged by the amount of sodium excreted in the urine, lower sodium excretion was associated with an increased risk of cardiovascular death, while higher sodium excretion did not correspond with increased risk of hypertension or cardiovascular disease complications, according to a study in the May 4 issue of JAMA.

Heart bypass surgery rates fall by 38% between 2001 and 2008: Study

According to latest the U.S. research, the number of heart patients getting bypass surgery fell by 38 percent between 2001 and 2008. This fall reflects several factors, including a decline in smoking rates, which has led to less coronary artery disease, said senior study author Dr. Peter Groeneveld, an assistant professor of medicine at the University of Pennsylvania School of Medicine.

Confusing research on salt and heart: Study

According to the latest European study, people who ate lots of salt were not more likely to get high blood pressure, and were less likely to die of heart disease than those with a low salt intake. This is contrary to what has been known till date. The U.S. guidelines recommend that Americans consume less than 2,300 milligrams of salt daily - 1,500 mg in certain people who are more at risk for high blood pressure or heart disease.

Merck's Phase III study shows efficacy results of tafluprost to treat ocular hypertension

Merck, known as MSD outside the United States and Canada, announced today that new Phase III data showed that patients with open-angle glaucoma or ocular hypertension, who were dosed once-daily with tafluprost, Merck's investigational, preservative-free prostaglandin analogue ophthalmic solution, experienced a reduction in intraocular pressure comparable to patients taking twice-daily preservative-free timolol maleate, a beta-adrenergic antagonist.

Animal studies reveal new route to treating heart disease

Scientists at Johns Hopkins have shown in laboratory experiments in mice that blocking the action of a signaling protein deep inside the heart’s muscle cells blunts the most serious ill effects of high blood pressure on the heart. These include heart muscle enlargement, scar tissue formation and loss of blood vessel growth.

Secondhand smoke exposure linked to high blood pressure in boys

Exposure to secondhand smoke, even at extremely low levels, is associated with increased blood pressure in boys, according to new research being presented Sunday, May 1, at the Pediatric Academic Societies annual meeting in Denver.

Study finds no significant link between religiosity and low blood pressure

Contrary to some earlier studies, a Loyola University Health System study has found that religious activity does not help protect against high blood pressure.

Most nurses are chronically sleep deprived

Sleep has become a hot button topic in health care, at least when it comes to physicians. The fact that doctors-in-training don't get enough of it has resulted in regulations governing duty hours in resident training programs across the nation. In 2002, the Accreditation Council of Graduate Medical Education (ACGME) reduced the number of hours that resident physicians can work to 80 hours per week.
