Look inside your heart Quantifying the damage caused to specific parts of the heart by cardiac arrest is key to providing effective treatment and accurate prognoses for millions of people worldwide. Now, researchers have developed a computational method that uses magnetic resonance imaging data to assess the extent of damage to the left ventricle, the heart’s powerhouse.
Studying cardiac arrhythmias in nematodes A simple model using the nematode Caenorhabditis elegans has been developed that can be used to test substances for treating genetically-mediated cardiac arrhythmias. They used the nematode feeding apparatus for this purpose, a rhythmically active muscle pump that resembles the muscle cells in the mammalian heart.
Novel prosthetic heart valve developed for treatment of severe heart disorder A novel prosthetic heart valve has been developed, known as VeloX, which can be implanted through a small incision for the treatment of a serious heart valve disorder called mitral regurgitation. This is a condition in which the mitral valve on the left side of the heart does not close properly. The device is particularly beneficial to patients who are of high surgical risk or are unsuitable for existing clinical interventions
Transplantation of unique, newly discovered stems cells may lead to promising stroke therapy When rats modeled with stroke were transplanted with newly discovered and unique Muse cells, neuronal regeneration resulted in significant improvements in neurological and motor functions and did not cause cancer, as other cells often do, scientists report.
Exercise and stop smoking to improve depression after heart attack Exercise and stop smoking to improve depression after a heart attack, experts urge.
