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)
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)
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)
Key finding in rare muscle disease
The finding is in the current issue of Annals of Neurology, a leading international neurology journal, in work led by Professor Nigel Laing and Dr Kristen Nowak of the Laboratory for Molecular Genetics at the Western Australian Institute for Medical Research (WAIMR) and done in collaboration with a number of European researchers. view more (2007-01-18)
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)
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)
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)
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)
Bleeding hearts revealed with new scan
Images that for the first time show bleeding inside the heart after people have suffered a heart attack have been captured by scientists, in a new study published today in the journal Radiology. view more (2009-01-20)
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)
Virtual robot outlines damaged heart muscle
In a joint project with the STW Technology Foundation, medical information technologists from Leiden have developed a virtual robot which meticulously scans the heart muscle using images of the heart. The contours detector reduces the work of specialists and does not affect the patients. The research group will present the results in the middle of... view more... (2002-05-23)
Children's Hospital scientists achieve repair of injured heart muscle in lab tests of stem cells
Researchers at Children's Hospital of Pittsburgh of UPMC have been able to effectively repair damaged heart muscle in an animal model using a novel population of stem cells they discovered that is derived from human skeletal muscle tissue. view more (2008-11-26)
Heart saves muscle
A heart muscle protein can replace its missing skeletal muscle counterpart to give mice with myopathy a long and active life. view more (2009-05-26)
Penn researchers discover 'modus operandi' of heart muscle protein
Researchers at the University of Pennsylvania School of Medicine have discovered that a protein called leiomodin (Lmod) promotes the assembly of an important heart muscle protein called actin. What's more, Lmod directs the assembly of actin to form the pumping unit of the heart. The findings appear in this week's issue of Science. view more (2008-04-11)
Oxygen-saturated blood reduces levels of damaged heart tissue following a heart attack
Results of a clinical trial published today in Circulation: Cardiovascular Interventions demonstrate that an infusion of blood that is "supersaturated" with oxygen (SS02) can reduce the amount of damaged heart muscle immediately following a life-threatening heart attack. view more (2009-09-16)
Pitt and University of Chicago Researchers Uncover Novel Process Behind Heart Muscle Contraction
Researchers from the University of Pittsburgh and the University of Chicago were able to control heart muscle function in a new way after discovering the previously unknown role of two enzymes in heart muscle contraction, as detailed in the April 11 cover story of the "Journal of Biological Chemistry." Although in the early stages, the... view more... (2008-04-10)
The benefits of reperfusion therapy
The wider use of reperfusion therapy in patients with heart attack (AMI) can save millions of lives in Europe. view more (2009-09-01)
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)
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)
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)
