Afib triggered by a cell that resembles a pigment-producing skin cell
The source and mechanisms underlying the abnormal heart beats that initiate atrial fibrillation (Afib), the most common type of abnormal heart beat, have not been well determined. view more (2009-10-13)
Heart derived stem cells develop into heart muscle
Dutch researchers at University Medical Center Utrecht and the Hubrecht Institute have succeeded in growing large numbers of stem cells from adult human hearts into new heart muscle cells. view more (2008-04-24)
Scientists in Japan design first optical pacemaker for laboratory research
The world's first optical pacemaker is described in an article published today in Optics Express, the Optical Society's open-access journal. A team of scientists at Osaka University in Japan show that powerful, but very short, laser pulses can help control the beating of heart muscle cells. view more (2008-05-28)
Bone marrow hope for heart sufferers
New hope for sufferers of heart disease is possible, after research led by a University of Leicester surgeon indicates that bone marrow cells injected into a heart can help repair damage from a heart attack. view more (2002-11-27)
Lighting up the heart
A major breakthrough in research could lead to improved recovery of the heart when it is re-started after a heart attack or cardiac surgery. view more (2006-09-22)
Altered sodium channel function linked to heart failure
The results of a study, using mice and heart muscle cells from rabbits, by researchers from Georg-August-University Göttingen, Germany, have provided a potential molecular explanation for the abnormally rapid heartbeats known as ventricular tachyarrhythmias (VTs) that can cause the sudden death associated with heart failure. view more (2006-11-27)
Heart regenerates after infarction -- first trials with mice
Up until today scientists assumed that the adult heart is unable to regenerate. Now, researchers and cardiologists from the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch and the Charité - Universitätsmedizin Berlin (Germany) have been able to show that this dogma no longer holds true. view more (2008-12-12)
ESC Congress 2004: Converting cells into heart muscle
Bone marrow derived stem cells can give rise to heart muscle cells. This plasticity concept - the ability of bone marrow cell to transdifferentiate into heart muscle cell - is supported by experimental and clinical data. Another possibility is to replace the missing function by causing transdifferentiation of existing cells. Transdifferentiation... view more... (2004-08-30)
Study: Fountain of youth for your heart?
An age-related decline in heart function is a risk factor for heart disease in the elderly. While many factors contribute to a progressive age-related decline in heart function, alterations in the types of fuels the heart uses to produce energy also play important roles. view more (2007-11-05)
Researchers examine developing hearts in chickens to find solutions for human heart abnormalities
When it is head versus heart, the heart comes first. The heart is the first organ to develop and is critical in supplying blood to the rest of the body. view more (2009-01-22)
Dampened hopes for transplanting bone marrow stem cells in heart attacks
There is little, if any, evidence that adult stem cells can build other cells in an adult organism than those formed in the organs they themselves come from. At any rate, blood stem cells do not convert to heart muscle cells in a damaged heart, which was previously hoped. This has been shown by a research team from the Stem Cell Center at Lund... view more... (2004-05-06)
Progress being made in exploring potential use of stem cells to treat heart disease
Scientists are making headway in exploring the potential future use of stem cells to treat heart disease, according to a review article in the current issue of Nature (June 29, 2006). view more (2006-06-29)
Researchers identify key step in cocaine-induced heart enlargement, sudden death
Cocaine, in concentrations commonly sold on the street, causes the abnormal buildup of primitive proteins in heart muscle - a process causing heart enlargement that can ultimately lead to sudden death. view more (2006-09-08)
Researchers find current drug can treat rare heart disorder
New research has found that the answer to treating a rare inherited heart disorder could lie with a drug already on the market. view more (2009-04-02)
Stem cell therapy successfully treats heart attack in animals
Final results of a study conducted at Johns Hopkins show that stem cell therapy can be used effectively to treat heart attacks, or myocardial infarction, in pigs. view more (2005-07-26)
Gladstone scientists identify key factors in heart cell creation
Scientists at the Gladstone Institute of Cardiovascular Disease have identified for the first time key genetic factors that drive the process of generating new heart cells. view more (2009-04-27)
Heart attack in a laboratory dish
NWO researchers at Utrecht University have given heart muscle cells a heart attack in the laboratory. This allowed them to observe clearly the change that takes place in the cell membrane during an attack and how the change sometimes leads to the death of the cell. In a healthy cell, one of the components of the membrane, the phospholipids, are... view more... (2001-05-08)
Stem cell regeneration repairs congenital heart defect
Mayo Clinic investigators have demonstrated that stem cells can be used to regenerate heart tissue to treat dilated cardiomyopathy, a congenital defect. view more (2008-09-12)
ESC Congress 2003: Stem cell therapy for myocardial repair & regeneration
IMPORTANT: This press release accompanies both a presentation and an ESC press conference given at the ESC Congress 2003. Written by the investigator himself/herself, this press release does not necessarily reflect the opinion of the European Society of Cardiology Heart attack and the resulting heart failure is still one of the leading causes of... view more...

While focusing on heart disease, researchers discover new tactic against fatal muscular dystrophy
Based on a striking similarity between heart disease and Duchenne muscular dystrophy, researchers at Columbia University Medical Center have discovered that a new class of experimental drugs for heart failure may also help treat the fatal muscular disorder. view more (2009-02-09)
