Hopefully this leads to a breakthrough in treating heart disease. This will be very helpful to many people. For example, you may have Heart disease that involves your blood vessels is often signaled by:These symptoms can be signs that your blood vessels have narrowed. I hope the research leads to some great developments.Thanks for the education Linda. The Duke scientists think that they may have found one.The scientists have created a patch that is likely large enough to cover damage in the human heart. Seek immediate medical attention if you’re concerned about any symptoms you have. In the hope of repairing damage to mouse hearts, University of Pennsylvania scientists created a mix of miRNA molecules known to be involved in cell replication signaling.
The patch is placed over the damaged section of the heart. In addition, a way of fully integrating it into the heart needs to be found. The do a lot of research at Duke University. My grandmother received an experimental heart treatment and it worked beautifully. Thanks for the information, Linda. A very necessary and amazing Hub; one filled with Light and much promise. Unlike the case in some parts of the body, the dead cells aren’t replaced with new ones. The potential uses of stem cells are certainly exciting.

Thank you for sharing such positive research; on a topic we're all concerned about.An educational topic and you know how to share such topics in detail. According to the Although it may seem that something so serious should have warning signs, it’s possible to develop heart disease without knowing it as you go about your daily life. The AV (atrioventricular) node is located at the bottom of the right atrium and is stimulated when the signal reaches it.Once the AV node is stimulated, it sends an impulse along the rest of the electrical conduction system (bundle of His, left and right bundle branches, and the Purkinje fibres) and triggers the ventricles to contract.An artificial pacemaker can be implanted in the heart to help SA node and electrical conduction problems. Scar tissue often forms in the area.A large area of damaged heart tissue may be debilitating for the patient and may lead to heart failure. Call 911 immediately if you experience these symptoms.
I think it's one of the sad facts of life that people die from horrible diseases when a relatively short while later much better treatments or even cures are found.I think about my dad...he died three days short of his fiftieth birthday from a heart attack. Smaller versions of the patch have been attached to mouse and rat hearts and have functioned like heart tissue, however. Have a great weekend!Thank you for the interesting and thought-provoking comment, Flourish. Great job as always.Thank you very much for the comment and the share, Patty!Thanks for this exciting information! (Mature red blood cells don't contain a nucleus or DNA.)

They no longer respond to electrical stimulation and don’t contract. I am amazed at the advancement in medicine since I was a little boy. The patient may experience problems if a large area of their heart is damaged.Two groups of scientists have created potential solutions for the problem of dead cardiac tissue. It's an interesting question to investigate, though.In the artistic representation of the DNA molecule shown above, the sides of the "ladder" represent the phosphate-deoxyribose backbone of each strand and the rungs represent the bonds between the bases that hold the strands together.Genes control the production of proteins. The scientists want to promote the proliferation of heart cells for long enough to be helpful and then to stop the process. Establishing a baseline for your health will help you and your doctor address any concerns that arise in the future.© 2005-2020 Healthline Media a Red Ventures Company.
