Injectable Gel Helps Heart Regenerate After Heart Attack
Researchers demonstrate an injectable gel that slowly releases short gene sequences known as microRNAs into the heart muscle, allowing it to regenerate after injury. In…
Beating Heart Patch Repairs Damage Caused by Heart Attack
Biomedical engineers at Duke University have created a fully functioning artificial human heart muscle large enough to patch over damage typically seen in patients who…
Researchers Compile First Atlas of the Healthy Human Heart
A healthy heart beats about two billion times during a lifetime – thanks to the interplay of more than 10,000 proteins. Researcher from the Max…
Yale Study Probes the Link Between Common Blood Clotting Conditions
New research from Yale University probes the link between common clotting conditions – atrial fibrillation and pulmonary embolism. Medical disorders related to blood clots are…
A Light-Reflecting Balloon Catheter Repairs the Heart without Surgery
Using a catheter aided by UV light, researchers have developed a new technique to repair holes in the heart without surgery. Harvard-affiliated researchers have designed…
New System Converts MRI Scans into 3D-Printed Heart Models for Surgical Planning
Engineers and computer scientists at MIT and Boston Children’s Hospital have developed a new system that can convert MRI scans of a patient’s heart into…
International Research Collaboration Reveals Mutations in DCHS1 Cause Mitral Valve Prolapse
Researchers reveal that mutations of the DCHS1 gene cause a common form of mitral valve prolapse. An international research collaboration led by Harvard Medical School…
Feeding Behavior in Worms May Help Shed Light on Human Heart Function
In a new study from MIT researchers reveal that a simple roundworm has the ability to spit out potentially deadly substances — a finding that…
Smartphones Can Disrupt Pacemakers and Cause Painful Shocks
Electromagnetic interference from smartphones can disrupt pacemaker function and cause implantable cardioverter defibrillators to deliver painful shocks. Cardiac device wearers are advised to keep a…
Research Shows There is a Medical Benefit to Reducing D2B Time
Newly published research reveals that doctors and emergency medical personnel have reduced the amount of time it takes to treat emergency heart patients, and shows…
Carbon Nanotube Patches Improve Heart Function
Using carbon nanotubes, researchers at Rice University and Texas Children’s Hospital have created heart-defect patches that improve electrical signaling between immature heart cells. Living heart…
Human Heart Precursor Cells Regenerate Decellularized Mouse Heart
A newly published study details how researchers used human heart precursor cells to get a decellularized mouse heart to beat again. Pittsburgh – For the…
Study Reveals Non-Inherited Mutations Account for Many Heart Defects
A new study found that non-inherited mutations account for many heart defects, suggesting that common pathways may underlie a wide range of common congenital diseases….
Protein Makes Old Hearts Younger, Reverses Some Effects of Aging
Researchers have identified a protein in the blood of mice and humans that may prove to be the first effective treatment for a form of…
SOLITAIRE Dramatically Outperforms Standard Brain Clot Removal Tool
A newly published study details the findings from a clinical study involving 113 stroke patients at 18 hospitals in which the FDA approved SOLITAIRE Flow…
