Beta Blocker News and Research

RSS

Beta-adrenergic receptor blocking agents (beta-blockers) are drugs with multiple actions on the heart. Blockade of beta-1 receptors results in slowing of heart rate, reduction in myocardial contractility, and lowering of systemic blood pressure. In the context of acute myocardial infarction (AMI), which represents a state of reduced oxygen supply to the affected portion of the heart, these effects may be beneficial as they result in reduced myocardial workload and oxygen demand. Furthermore, beta-blockers may reduce the risk of ventricular arrhythmias, which are an important cause of death following AMI.

ESC welcomes 'intriguing' study on heart failure

The European Society of Cardiology (ESC) welcomes an "intriguing" study, published today in the Journal of the American College of Cardiology, featuring a completely novel approach for improving endothelial function in heart failure.

SSRI use raises risk of fall among elderly with dementia: Study

A new study reveals that nursing home residents with dementia who use selective serotonin reuptake inhibitors (SSRIs) have an increased risk of having a fall that causes injury compared with those who do not use SSRIs. Additionally those using average doses have 3 times the risk compared with nonusers, the authors, led by Carolyn S. Sterke, from Erasmus University Medical Center, Rotterdam, the Netherlands, report. Authors write, “Even at low doses, SSRIs are associated with increased risk of an injurious fall in nursing home residents with dementia.”

Beta blockers prevent negative effects of stress

Stressed people fall into habits and their behaviour is not goal-directed. That the neurotransmitter norepinephrine plays a decisive role here is now reported in the Journal of Neuroscience by scientists from Bochum led by Dr. Lars Schwabe (RUB Faculty of Psychology).

Blocking CaM kinase may help prevent cardiac rupture

For people who initially survive a heart attack, a significant cause of death in the next few days is cardiac rupture -- literally, bursting of the heart wall. A new study by University of Iowa researchers pinpoints a single protein as the key player in the biochemical cascade that leads to cardiac rupture.

Eliminating drug co-pays improves medication adherence in heart attack patients

The use of specific medications following a heart attack has been shown to reduce cardiovascular events and mortality, however; while highly effective, the rate of adherence to these medications is poor. Researchers from Brigham and Women's Hospital (BWH) evaluated whether eliminating co-payments for these medications would increase adherence and improve outcomes in patients who have had a heart attack.

Multiple medication use may increase severity of erectile dysfunction

The use of multiple medications is associated with increased severity of erectile dysfunction, according to a Kaiser Permanente study published online in the British Journal of Urology International.

Treatments can help most HCM patients

Most of the 600,000 Americans with hypertrophic cardiomyopathy (HCM) -- a genetic heart muscle disease -- can live normal life spans, according to the first science-based guideline for diagnosing and treating this disorder.

Broader screening for hypertrophic cardiomyopathy

Around one in 500 Swedes carry a genetic mutation which can cause sudden cardiac death. The diagnosis can lead to major lifestyle changes, but quality of life can be maintained with the right advice and support, reveals a new study from the Sahlgrenska Academy at the University of Gothenburg, Sweden.

Beta-blockers can prevent breast cancer metastasis and improve survival

Cancer Research UK scientists are investigating whether beta-blockers hold the key to preventing breast cancer spread and improving survival. Promising early results will be presented on the eve of breast cancer awareness month at the Royal Society of Medicine.

Research roundup: Widows and medical spending; disparities in heart care, hospital deaths

The authors write: "We find that out-of-pocket medical spending is approximately 29 percent higher when an individual becomes widowed, a large portion of which is spending on nursing homes. Our results suggest a substantial role of living arrangements in out-of-pocket medical spending; however, our estimates combined with differences in rates of widowhood across gender suggest that marital status can explain only one third of the gender difference in total out-of-pocket medical spending, leaving a large portion unexplained.

Beta-blocker drugs may improve survival time for melanoma patients

Beta-blocker drugs, commonly used to treat high blood pressure, may also play a major role in slowing the progression of certain serious cancers, based on a new study.

Cheap medicines could prevent huge number of deaths from heart attacks, strokes

A major new international study involving researchers from the Sahlgrenska Academy at the University of Gothenburg and Sahlgrenska University Hospital has revealed that aspirin, statins, beta blockers and ACE inhibitors are prescribed far too infrequently. They are cheap, preventive medicines that could prevent a huge number of deaths from heart attacks and strokes.

Clinical trial to evaluate RMN system for treatment of ischemic Ventricular Tachycardia

Results from the STOP-VT Study were presented at the ESC Congress 2011 today. This is the first ever multi-center, global, prospective trial to evaluate a Remote Magnetic Navigation system for the treatment of ischemic Ventricular Tachycardia.

Strong link between leisure-time physical activity and AF among men

A Norwegian survey carried out between 1974 and 2003 showed that there was a graded independent increase in the risk of AF with increasing levels of physical activity in a population-based study among men with ostensibly no other heart disease. In women the data were inconclusive.

Scientists identify molecular pathway that plays a key role in stress-related DNA damage

Working closely with a team of researchers from Duke University, scientists from the Florida campus of The Scripps Research Institute have helped identify a molecular pathway that plays a key role in stress-related damage to the genome, the entirety of an organism's hereditary information.

Scientists discover mechanism that helps explain why stress causes DNA damage

For years, researchers have published papers that associate chronic stress with chromosomal damage. Now researchers at Duke University Medical Center have discovered a mechanism that helps to explain the stress response in terms of DNA damage.

Stress management can improve chronic skin conditions

As anyone with a chronic, inflammatory skin condition, such as psoriasis, rosacea or acne, knows, dealing with unpredictable flares can cause considerable stress and have a negative impact on a person's overall well-being.

Essential criteria for clinical diagnosis of restless legs syndrome

We've all experienced abnormal sensations in our legs at one time or another, but for as many as 10 percent of the US population, restless legs syndrome (RLS) is a daily occurrence. Characterized by throbbing, pulling, tingling, itching, and crawling sensations, RLS is a neurological disorder that produces unpleasant physical sensations in the extremities and an urge to counteract that sensation by movement.
