More than Half Hospitalized Stroke Patients Likely Treated for Hypertension Against Guidelines

28.07.2004


As many as 65 percent of stroke patients are likely to be treated with antihypertensive medications during the first four days of hospitalization, despite current guidelines of the American Stoke Association that recommend against treating all but the most severe cases of hypertension during the first few days following a stroke. A recent retrospective study found that nearly all stroke patients who were being treated for hypertension prior to admission had their medication regimens continued or intensified, and a third who were not taking medications for hypertension had antihypertension treatment initiated during the hospitalization. Study details are published in the July 27 issue of Neurology.



Hypertension (high blood pressure) is common at the time of an ischemic stroke and is believed to be the body’s response that maintains adequate blood flow to the area immediately around the stroke site. Lowering elevated blood pressure through medication, while an appropriate measure in stroke prevention, can result in the extension and worsening of acute stroke symptoms, and has even been shown to result in worse short- and long-term outcomes.

The dangers of antihypertensive therapy in the setting of acute ischemic stroke have been recognized for some time. Despite active efforts to promote clinical guidelines, first established in 1994, little is known about how often, and under what circumstances, antihypertensive agents are used in the treatment of patients with acute ischemic stroke. “We sought to determine whether the use of antihypertensive agents was consistent with guidelines, and if such use placed patients at further risk of negative outcomes,” noted study author Peter Lindenauer, MD, MSc, of Baystate Medical Center and Tufts University School of Medicine, Springfield.


For the study, researchers reviewed the medical records of 154 patients admitted in 2000 for acute ischemic stroke at Baystate Medical Center, a community-based teaching hospital that serves as the western campus of Tufts University School of Medicine. Overall, the incidence of hypertension severe enough to warrant antihypertensive treatment (according to guidelines) was low, varying from 17 percent among those whose medications regimens were continued to 36 percent among those whose regimens were intensified. Only 26 percent of patients who had antihypertensive therapy initiated in the hospital met guideline criteria for treatment.

The majority of the patients who were prescribed antihypertensive medications experienced relative hypotension on the days that they received treatment, and one in 20 treated patients developed frank hypotension.

“Antihypertensive agents are used more frequently in the care of stroke patients than is currently recommended by clinical practice guidelines,” concluded Dr. Lindenauer. “In light of how frequently stroke is encountered in the hospital setting, continued research focused on blood pressure management should be supported.” In the meantime, Lindenauer emphasized that greater efforts should be made to educate physicians about the potential risks associated with this practice.

Stroke is a leading cause of disability and the third leading cause of death in the United States.

The American Academy of Neurology, an association of more than 18,000 neurologists and neuroscience professionals, is dedicated to improving patient care through education and research. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as stroke, Alzheimer’s disease, epilepsy, Parkinson’s disease and multiple sclerosis.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
