New therapy can heal damage of heart attack

May 11, 2019

New Delhi, May 11 (ANI): Researchers have discovered a therapy through which they can induce heart cells to regenerate after a heart attack. Myocardial infarction, more commonly known as a heart attack, caused by the sudden blocking of one of the cardiac coronary arteries, is the main cause of heart failure, a condition that now affects over 23 million populations in the world, according to the study published in Journal Nature. At present, when patients survive a heart attack, they are left with permanent structural damage to their heart through the formation of a scar, which can lead to heart failure in the future. Researchers have delivered a small piece of genetic material, called microRNA-199, to the heart of pigs, after a myocardial infarction which resulted in the almost complete recovery of cardiac function at one month later.
