Method of recovery of the heart muscle, passed through the scarring after a heart attack, doctors will be available over the next 10 years. It is a new word in the treatment of heart attack.
Scarring of heart tissue after a heart attack leads to a sharp weakening of the heart that is unable to pump enough blood. Over time, this can lead to heart failure, and even death of the patient. It is because of the victim's severe scarring of heart attacks go on disability and physical activity, it had seemed trifling, suddenly become unbearable.
From scarring tissue after a heart attack in the world suffers up to 23 million people, according to WHO. Researchers at Duke University Medical Center in the US have developed a simple process for the conversion healed tissue in a healthy and fully functioning heart muscle, which may be the most powerful tool Treatment of heart attack . And it does not require transplantation of stem cells, the use of which many scientists are studying.
Instead, the Americans noticed the microRNA molecules that serve as key regulators that control the activity of multiple genes. It has been allocated a specific combination of three microRNAs, which allows you to turn healed tissue cells (fibroblasts) into the cells of the heart muscle.
In laboratory tests in contact to the fibroblasts miroRNK these reprogrammed cells, transforming them into cardiomyocytes, which consists of the heart muscle. The same effect has been achieved in the course of experiments on living mice. If the experiment proves to be effective in humans, it will go into wide clinical practice as a method of Treatment of heart attack For 10 years.
