Prehypertension triples heart attack risk

05.08.2005


American Heart Association rapid access journal report:

People with prehypertension are at much higher risk of heart attack and heart disease, according to a study published in Stroke: Journal of the American Heart Association.

"If we were to eliminate prehypertension, we could potentially prevent about 47 percent of all heart attacks," said the study’s lead author Adnan I. Qureshi, M.D., professor and director of the Cerebrovascular Program in the Zeenat Qureshi Stroke Research Center at the University of Medicine and Dentistry of New Jersey in Newark.



Normal blood pressure is lower than 120/80 millimeters of mercury (mm Hg). Prehypertension is systolic blood pressure between 120 and 139 and/or diastolic pressure between 80 and 89 mm Hg. (Systolic pressure is the force in the arteries when the heart beats and diastolic pressure is the force when the heart is at rest.) Hypertension is blood pressure 140/90 mm Hg or higher.

"There is a gray zone, where you are not hypertensive but your blood pressure is not normal either," he said.

More than a year ago, a national committee coined the term "prehypertension" for this gray area. But until this study, Qureshi said, physicians and the public knew little about what this term meant. About 59 million people in the United States are prehypertensive.

Researchers examined existing data from the Framingham Study and found that a prehypertensive person is more than three times more likely to have a heart attack and 1.7 times more likely to have heart disease than a person with normal blood pressure.

They did not find a significantly increased risk of stroke among those with prehypertension. "This is somewhat surprising, but it may be related to the small number of stroke events in the study," Qureshi said. "The differential effect in this gray zone may be mediated through factors other than blood pressure, such as insulin resistance."

Researchers also investigated the population’s attributable risk, which determines how a disease will be impacted if that risk factor were eliminated.

"While we classically recommend lifestyle modifications such as weight control, regular physical activity and changes in diet for people with prehypertension, these findings raise the question of whether we should treat prehypertensive patients more aggressively."

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
