Heart is the part of the body which one cannot part with. Imagine pumping blood to all parts of the body, non-stop for virtually more than 50 years at least. Isn't that a tiring job. Yes it is and it would wear down any machine. Heart is no different.

The cells of the body after reaching a certain stage stop to grow and divide which then increases the risk of dead and damaged tissues or cells not being replaced. The cells of the heart have the same fate.

However, science has a way around almost everything these days. Almost.

Coaxing the cells to grow beyond their lifespan is what scientists have come up with.



Scientists say they have found a new way to mend damage to the heart.

When cells turn into fully-formed adult heart muscle they stop dividing, and cannot replace tissue damaged by disease or deformity.

But a US team have found a way to coax the cells to start dividing again, raising hopes they could be used to regenerate healthy tissue.

The study, carried out on mice and rats by Children's Hospital Boston, appears in the journal Cell.

The researchers say their work could provide an alternative to stem cell therapy, which is still largely untested, and carries a potential risk of side effects.

In theory, it could be used to treat heart attack patients, those with heart failure and children with congenital heart defects.

The key ingredient is a growth factor known as neuregulin1 (NRG1).

The Boston team envisages patients going to a clinic for daily infusions of NRG1 over a period of weeks.

However, researcher Dr Bernhard Kühn said more work to established the safety of the therapy before it could be tested in humans.

Interesting and yet not new. I remember reading a research paper from the UK that tried to use the characteristic of Cancer to restart cell division and repair damaged organs.

Heart Damage

In the cases of heart attack and cardiac arrest, or any other heart shocks, time sets to be the most crucial factor for the survival of the patient. Sometimes, a little knowledge regarding the immediate actions to be taken may help your near and dear ones to survive in such incidents. Keith Churchwell has extraordinarily explained the pros and cons while handling patient suffering immediate heart attack or cardiac arrest. The response a person takes to treat a victim decides the probability of his/her survival. Its been my personal experience fighting to survive against a heart attack. A quick recognization of your bodily responses may increase your chances of survival. Because of having many heart problems, I was enrolled in a concierge Healthcare program from elite health. I was attacked by a severe heart attack in a party, luckily surrounded by many people. Some of the sudden changes in my body was recognized by me and anticipated immediately. I got a very severe chest pain which was almost unbearable for more than a minute. I got the suspicion that I might be having heart attack, and immediately called my physician on the phone, and explained my condition and its severity. Because of the immediate guidance, I was directed immediately to have an aspirin which I used to carry with me as prescribed by my physician. It was quite a frightening experience for me to face such a heart attack, but somehow I managed to be calm until 911 arrived. I was immediately taken to the nearest hospital, where already my physician were present and have got everything setup according to my medical history. And it was in some matter of seconds that everything was in control. A doctor, who already have the complete knowledge of the medical history and fitness of the person, extra ordinarily ameliorate your recovery process. Hence such a concierge level program from Elite health, helped me a save my life, like many others.
