Researchers found that embryonic stem cells can survive in damaged heart muscle and improve cardiac function. The study demonstrated significant reduction of MI damage and improvement in left ventricular function, suggesting a potential future treatment option for congestive heart failure.
Researchers at Columbia University have discovered a treatment for heart failure by correcting a specific cellular defect. Beta blockers prevent the excessive phosphorylation of the ryanodine receptor, allowing it to respond to signals and release calcium ions as needed. This finding offers new hope for treating heart failure.
Researchers found that troponin levels can accurately predict future heart attack risk, even when traditional measures are negative. The study suggests using troponin as a reliable indicator of cardiac cell damage, rather than creatine kinase-MB, to detect high-risk patients.
A UCSF study finds that eptifibatide helps preserve microvasculature and blood flow into the heart muscle, improving oxygen supply to patients undergoing angioplasty. The drug improves large artery blood flow by 39% and microvascular blood flow by 84%, potentially reducing irreversible heart injury.
Researchers have successfully created viable new heart muscle cells using marrow stromal cells from an animal's own bone marrow. The goal is to replace dead heart muscle cells with new ones, potentially offering a treatment for life-threatening heart failure.
Scientists at Johns Hopkins have developed a new noninvasive test that measures creatine levels in the heart, which can indicate muscle damage from a heart attack. The test uses MRI and MRS to pinpoint depleted concentrations of creatine in injured heart tissue.
Duke University Medical Center is testing a new laser system to pierce blood-carrying channels in ailing heart muscle, showing promising results for eight treated patients. The procedure, known as transmyocardial revascularization (TMR), creates new passageways that increase oxygenation and functional heart muscle.
Researchers discovered a strong correlation between mumps virus infection and infantile rapid progression of congestive heart failure (EFE), with 72% of cases positive for the virus. The study's findings support the development of a vaccine against adenovirus, which is currently being produced but not widely available.
