Heart Failure News and Research

RSS

Heart failure (HF) is a condition in which a problem with the structure or function of the heart impairs its ability to supply sufficient blood flow to meet the body's needs. It should not be confused with cardiac arrest or myocardial infarction.

Doctors' questions about end-of-life legalities may result in patient pain

When treatment options dwindle or are exhausted, terminally ill-patients often opt for pain management and comfort over life-extending therapies.

Cigarette smoke may reshape the left ventricle

Prolonged exposure to cigarette smoke can increase levels of the stress hormone norepinephrine and enzymes in the heart that have the potential to reshape the left ventricle, according to new research at the University of Illinois at Chicago.

Doctors' questions about end-of-life legalities may result in patient pain

When treatment options dwindle or are exhausted, terminally ill-patients often opt for pain management and comfort over life-extending therapies. However, a team of researchers from Wake Forest University Baptist Medical Center, University of Rochester Medical Center and Unity Health System, report that a lack of thorough understanding about the laws governing end-of-life care may be leaving many medical providers with an ethical dilemma and causing some terminally-ill patients considerable, unnecessary pain.

Research shows why some heart failure treatments fail

Do the biological underpinnings of heart failure share more in common with cancerous tumors than other cardiovascular diseases?

Blood levels of resistin a new biomarker for heart failure

Blood levels of resistin, a hormone produced by fat cells, can independently predict an individual's risk of heart failure, cardiologists at Emory University School of Medicine have found.

Adults with severe heart failure have more doctor visits, medications than others on Medicare

Adults with severe heart failure see almost three times as many Medicare providers each year compared to a typical beneficiary, according to research presented at the American Heart Association's Scientific Sessions 2008.

Gender matching between donors and recipients important to survival in heart transplantation

Gender matching between donors and recipients is important to short- and long-term survival in heart transplantation, according to a retrospective study presented at the American Heart Association's Scientific Sessions 2008.

Regularly exercise good for heart failure patients

Heart failure patients who regularly exercise fare better and feel better about their lives than do similar patients who do not work out on a regular basis, say researchers at Duke University Medical Center.

African-Americans with depression and heart attack have greater risk of death

African-American patients with acute myocardial infarction (MI) and previously treated depression that persists at their MI hospitalization have an increased risk of post-MI death, according to Emory researcher Susmita Parashar, MD, MPH.

Hydrogen sulfide could be used to treat humans with heart failure

At low concentrations, the toxic gas hydrogen sulfide protects the hearts of mice from heart failure, scientists at Emory University School of Medicine have found.

Scientists map steps to block enzyme phosphodiesterase 5's action in heart failure

Taking a cue from the way drugs like Viagra put the biological brakes on a key enzyme involved in heart failure, scientists at Johns Hopkins have mapped out a key chemical step involved in blocking the enzyme.

Racial disparities found in access and use of organ transplantation in children listed for heart transplant

Minority children awaiting a donor heart for transplant have a higher death rate than white children, even after controlling for clinical risk factors, according to research presented at the American Heart Association's Scientific Sessions 2008.

Catheter ablation works better than drugs for heart rhythm disorder

Treating a common heart rhythm disorder by burning heart tissue with a catheter works dramatically better than drug treatments, a major international study has found.

Diuretic reduces risk for type of heart failure that affects women more often than

New research by The University of Texas School of Public Health shows that a medication for high blood pressure called a diuretic or water pill is particularly effective at reducing the risk for a type of heart failure that affects women more often than men.

New blood test identifies sickest heart failure patients in ER

A new blood test identifies the sickest heart failure patients better than tests now used in emergency departments, researchers reported at the American Heart Association's Scientific Sessions 2008. Results of the Mid-Regional pro-Adrenomedullin (proADM) versus BNP and NTproBNP as Prognosticator in Heart Failure Patients: Results of the BACH Multinational Trial were presented as a late-breaking clinical trial.

Timing is everything for some heart attack patients

There is strong evidence that getting to the hospital quickly during a heart attack is critical, since early treatment saves both lives and heart muscle. And if the responsible coronary artery is completely blocked, it should be opened as soon as possible.

Exercise training safe in heart failure patients - offer clinical benefit

Exercise training is safe in heart failure patients, does not significantly reduce hospitalization or death, but is associated with several improved clinical outcomes, even in those already receiving optimal medical care, researchers reported at the American Heart Association's Scientific Sessions 2008. The Heart Failure and A Controlled Trial Investigating Outcomes of Exercise Training (HF-ACTION) was presented as a late-breaking clinical trial.

Interferon eliminates specific causes of some viruses in heart failure patients, improving clinical outcomes

Giving interferon to heart failure patients with evidence of a chronic viral infection safely eliminated two viruses from their systems and reduced levels of a third virus.

Obesity raises levels of hormone leptin

Obese people who don't have high cholesterol or diabetes might think they're healthy - despite the extra pounds.

Secondary prevention program may reduce risks after heart attack

An intensive, comprehensive, long-term secondary prevention program lasting up to three years after cardiac rehabilitation appears to reduce the risk of a second non-fatal heart attack and other cardiovascular events, according to a report in the November 10 issue of Archives of Internal Medicine , one of the JAMA/Archives journals.
