Low Blood Pressure News and Research

RSS

Hypotension is low blood pressure. Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood. Blood pressure is measured as systolic and diastolic pressures. Systolic blood pressure is the pressure when the heart beats while pumping blood. Diastolic blood pressure is the pressure when the heart is at rest between beats. You will most often see blood pressure numbers written with the systolic number above or before the diastolic, such as 120/80 mmHg. (The mmHg is millimeters of mercury-the units used to measure blood pressure.) Normal blood pressure in adults is lower than 120/80 mmHg. Hypotension is blood pressure that's lower than 90/60 mmHg.

Study compares early restrictive and liberal fluid management for sepsis-induced low pressure

Vanderbilt University Medical Center had a leading role in a large national study designed to compare two early interventions in the treatment of patients with sepsis, the body's severe response to an uncontrolled infection.

Risks and benefits of recently approved Alzheimer’s drug

The U.S. Food and Drug Administration (FDA) recently granted approval to Lecanemab, the first Alzheimer's disease treatment to win approval since the largely failed rollout of Aduhelm two years ago.

Using induced pluripotent stem cells to recreate the adrenal gland in a petri dish

Sitting atop the kidneys, the adrenal gland plays a pivotal role in maintaining a healthy body. Responding to signals from the brain, the gland secretes hormones that support critical functions like blood pressure, metabolism, and fertility.

Areas hospitable to Lassa virus spread may extend in the next several decades

In the study, which appeared on September 27 in Nature Communications, scientists analyzed decades of environmental data associated with Lassa virus outbreaks, revealing temperature, rainfall and the presence of pastureland areas as key factors contributing to viral transmission.

Study shows the importance of night-time blood pressure assessment for diagnosing hypertension

Around 15% of people aged 40-75 may have a form of undiagnosed high blood pressure (hypertension) that occurs only at night-time.

Healthy people with high cholesterol don't stand to benefit from statins, research says

About 40 million adults in the United States regularly take statins to lower their cholesterol levels and reduce their risk of heart disease and stroke, according to American Heart Association data from 2020.

Lower brain tissue oxygenation puts frailer older adults with multi-morbidity at risk of faints and falls

Researchers from Mercer's Institute for Successful Ageing (MISA) and the Department of Medical Physics at St James's Hospital and Trinity College Dublin have discovered that brain tissue oxygenation is lower in frailer older adults with multiple health conditions (multi-morbidity), putting them at risk of faints and falls. Brain oxygenation - the measure of oxygen in brain tissue - reflects the balance between oxygen delivery and consumption and is vital for the maintenance of normal brain function and tissue integrity.

Better, safer treatment option than saline solution may be available for hospital patients

A new study by researchers at Intermountain Healthcare in Salt Lake City finds there may be a better and safer treatment option for emergency department and hospital patients than saline solution, which is used as an IV fluid and is one of the most prescribed medical therapies in the United States.

Dosing recommendations should always be respected while taking herbal supplements

Herbal supplements may be natural, but that does not mean they are always safe. A new case report appearing in Heart Rhythm Case Reports, an official journal of the Heart Rhythm Society, published by Elsevier, is a case in point.

Cedars-Sinai geriatricians create program to catch at-risk older adults before they fall

Falls and broken bones are common among older adults, but they're not a natural part of aging. That's why Cedars-Sinai geriatricians created a bone health and falls risk consultation program to catch at-risk people before they break a bone or help them avoid another fracture in the future.

Age and higher ferritin levels associated with more severe MIS-C

A new study found that older children and those with high blood markers for inflammation (ferritin) were at highest risk of severe multisystem inflammatory syndrome in children (MIS-C) and admission to the intensive care unit (ICU).

A cluster of cells in the brainstem found to control the body's response to severe blood loss

University of Virginia School of Medicine scientists have discovered a cluster of cells in the brainstem that controls the body's response to severe blood loss, a finding which could benefit efforts to develop new treatments for traumatic injuries.

High blood pressure genes improve outcomes after congenital heart defect repair surgery

Children with a genetic makeup that predicts high blood pressure as adults are more likely to survive congenital heart defect repair surgery, according to a new study published in Circulation Research.

Study points to vagus nerve dysfunction as a central pathophysiological feature of long COVID

New research to be presented at this year's European Congress of Clinical Microbiology and Infectious Diseases (ECCMID 2022, Lisbon, 23-26 April) suggests that many of the symptoms connected to post-COVID syndrome (PCC, also known as long COVID) could be linked to the effect of the virus on the vagus nerve – one of the most important multi-functional nerves in the body.

Oral penicillin may be a safer option for people with high-risk rheumatic heart disease

A growing body of evidence indicates that some people thought to have an allergic response to injectable penicillin, the standard treatment for rheumatic heart disease, may instead be experiencing a cardiac reaction to the medicine, according to a new American Heart Association presidential advisory published today in Journal of the American Heart Association.

Study compares the survival rates of cardiac arrest in catheterization lab, versus the OR and ICU

People who went into cardiac arrest in the cardiac catheterization lab were more likely to survive to hospital discharge than those who had a cardiac arrest in the intensive care unit (ICU), yet less likely to survive than those who had an arrest in the operating room (OR), according to preliminary research to be presented at the American Heart Association's Resuscitation Science Symposium (ReSS) 2021.
