For a long time we have been told the same thing about the heart. Once you take damage, that’s it. Heart cells do not grow back. After a heart attack, the muscles are scarred and damaged, so doctors focus on managing what’s left. This idea has shaped the way we think about recovery for decades.But Australians study I am gently pushing back against that belief. It’s not about hype or wild promises. With careful data and quiet hope.“Pioneering research by experts at the University of Sydney, the Baird Research Institute and Sydney’s Royal Prince Alfred Hospital shows that heart muscle cells regenerate after a heart attack, opening the possibility of new regenerative treatments for cardiovascular disease,” the University of Sydney said in a statement. “Until now, we have thought that as heart cells die after a heart attack, that part of the heart is irreparably damaged, reducing the heart’s ability to pump blood to the body’s organs. Our research shows that after a heart attack, the heart is scarred, but new muscle cells are generated, opening up new possibilities. This new finding that muscle cells regenerate is exciting, but it also It’s not enough to prevent the devastating effects, so we hope to eventually develop a treatment that can amplify the heart’s natural ability to generate new cells and regenerate the heart after a stroke,” explained Dr. Robert Hume, lead author of the School of Medicine and Health and Charles Perkins Center and director of translational research at the Baird Institute for Applied Heart and Lung Research.

heart disease and india

In 2021, India reported a total of 2,873,266 deaths due to cardiovascular diseases (as per World Heart Observatory data). “Cardiovascular diseases caused an estimated 17.9 million deaths in 2016, representing 31% of all deaths worldwide. 85% of these deaths were due to heart attacks and strokes,” according to the World Health Organization (who). “In 2016, India reported 63% of total deaths due to NCDs, of which 27% were due to CVDs. CVDs also accounted for 45% of deaths in the age group of 40-69 years,” WHO said.“So this study is basically trying to find out if heart cells can regenerate. So we know all the conditions that occur in the heart, whether it’s ischemia or infarction. An infarction is a heart attack, and when you have a heart attack, the cells die.” Now, human heart cells do not have the ability to regenerate. Unlike the liver, the heart does not have the ability to regenerate. However, this study only showed that it is trying to regenerate cells through mitosis, and we know clinically that this is not important. Therefore, our patient does not benefit from this small amount of mitosis that happens to regenerate. So you can see that there have been attempts for 30 years to use stem cells to regenerate this heart muscle,” he said. Balbir Singh, Chairman, Cardiac Science Group, Pan Max and Head, Interventional Cardiology and Electrophysiology, Saket, Max Super Specialty Hospital, told TOI Health.“So you can try to improve regeneration by injecting stem cells into the heart, but nothing helps. So far nothing has worked. So this attempt to promote regeneration would be a very big step,” he added. “This discovery represents a major change in the treatment of end-stage heart disease, and many, many patients will benefit from it,” said Dr. Balbir.
