Cardiomyopathy News and Research

RSS

Cardiomyopathy is a group of diseases with primary, usually diffuse, involvement of the myocardium. The myocardial disease is not secondary to ischaemic, valvular, congenital or pericardial disease.

Mutated gene causes serious heart disease in newborns

The research group of professor Manfred Kilimann at the Department of Cell and Molecular Biology has elucidated the genetic cause of a severe heart disease in newborn children. This result will be published in the June issue of the American Journal of Human Genetics this week.

New method for the study of ion channel gating kinetics

An ion channel is a protein pore that lets ions (charged atoms such as calcium) pass through a cell's membrane. The method fits data to a new class of models, called manifest interconductance rank (MIR) models, which will give researchers a better understanding of the mechanisms by which ion channels open and close.

New heart valve ring helps congestive heart failure patients regain lost heart function

A new heart valve ring appears to help congestive heart failure patients regain lost heart function, reversing the disease's effects on heart structure in two ways and easing their disabling symptoms, researchers reported here today at the 85th Annual Meeting of the American Association for Thoracic Surgery.

Why different tissues in the human body vary in their susceptibility to "amyloid" diseases

Researchers at The Scripps Research Institute are reporting the results of a recent study that addresses why different tissues in the human body vary in their susceptibility to "amyloid" diseases, which include Alzheimer's disease and a cluster of ailments called the familial amyloidoses.

Sildenafil prevents anti-cancer drug induced heart damage

Virginia Commonwealth University researchers have found that the popular impotence drug Viagra prevents damage to the heart from a potent chemotherapeutic agent frequently used in the treatment of breast cancer, leukemia and sarcomas.

Alcoholism reduces male heart muscle’s ability to synthesize protein

The fact that men and women react differently to alcohol consumption and addiction, health and behavior risks, disease and death is well known and accepted. Women get drunker faster on less alcohol than men, but fewer women drink either occasionally or heavily, and men are more likely to become dependent on alcohol.

Doctors raise concern about heart drug Nesiritide

Doctors raise concern about heart drug. The heart drug Nesiritide (Natrecor) is an FDA-approved drug for the treatment of decompensated heart failure, the most common reason for hospitalization for those over 65 years of age.

Small hearts make big difference for young transplant recipients

When a young child is in need of a heart transplant, the problem is not the intricate surgery, but the scarcity of donors.

Sudden emotional stress can result in severe but reversible heart muscle weakness

Shocking news, such as learning of the unexpected death of a loved one, has been known to cause catastrophic events, such as a heart attack.

Genetic defect leads to electrical instability and mechanical pump failure

In genetic mapping of a large family with several members affected by a type of heart failure called dilated cardiomyopathy (DCM), the Mayo Clinic team found a defect in a gene on chromosome 3 called SCN5A.

Molecular pathway turns a juvenile heart into an adult heart

Researchers at the University of California, San Diego (UCSD) School of Medicine have discovered the molecular sequence of events in mice that turn a juvenile heart into an adult heart capable of responding to increased workloads.

Potential cure for lymphoma in HIV patients

Stem cell transplants have become the standard of care for patients with relapsed lymphoma, but not for patients who suffer from both this disease and HIV.

Living alone, financial difficulties, excessive use of alcohol associated with the onset of depression among outpatients with heart failure

Living alone, financial difficulties, excessive use of alcohol and poor results on a heart failure questionnaire were associated with the onset of depression among outpatients with heart failure, according to a new study in the Dec. 21, 2004 issue of the Journal of the American College of Cardiology.

Heart Hospital begins experimental cell therapy

Physicians at the Heart Hospital became the first team in the UK to treat a patient with an experimental new therapy designed to repair damage to cardiac muscle resulting from a heart attack. If successful, this treatment would give doctors the ability to improve the hearts of people with heart failure, rather than just treating the symptoms.

Troponin genes offer new insights to familial heart failure

Mutations in the troponin protein complex may be useful for predicting the course of heart failure due to dilated cardiomyopathy and also for guiding treatment and research, according to a new study in the Nov. 16, 2004 issue of the Journal of the American College of Cardiology.

Fluorescent protein tool may speed identification of molecular changes that reveal cells' inner workings

Scientists at Johns Hopkins and the University of Texas Medical Branch have created a new tool that easily reveals when and where a key cellular signal is active.

Women with arrhythmias may also benefit from implantable cardioverter-defibrillators

A small study of patients with heart failure not caused by blocked arteries indicates that women, as well as men, may benefit from implantable cardioverter-defibrillators (ICD), reported researchers at the American Heart Association’s Scientific Sessions 2004.

Two hearts are better than one for toddler

Camila Gonzalez now has two hearts beating separate rhythms inside her tiny chest. At 22 months of age, she became the youngest child in the United States to receive a donor’s heart while also retaining her original one.

Fourth gene found for distal muscular dystrophy

MDA grantees Peter Hedera, a neurologist at Vanderbilt University in Nashville, Tenn., and Nigel Laing, a molecular biologist at the University of Western Australia, were part of a team that identified a fourth gene that, when flawed, leads to distal muscular dystrophy (DD).

Heart pump improves quality of life in congestive heart failure patients

The most seriously ill congestive heart failure patients live longer and have a better quality of life if implanted with a heart pump, researchers report in Circulation: Journal of the American Heart Association.
