New hope for patients with heart attack

Canadian researchers have begun an experiment to use genetically modified stem cells to aid in the treatment of heart muscle damage in patients with heart attacks.

The reporter in Ottawa quoted a September 5 statement by Dr. Duncan Stewart, director of science at the Ottawa Hospital Research Institute, stressing that in this trial, researchers used stem cells. , extracted from the blood of patients within a few days or weeks after a heart attack.

Scientists will then seek to "upgrade" these original cells with a genetic gene called the endothelial nitric oxide synthase to stimulate blood vessel growth and improve tissue healing. serious heart damage.

These genetically altered stem cells are then transferred into the heart of a coronary patient who has had a heart attack.

Dr. Stewart said: "Stem cells have the amazing ability to repair and regenerate damaged organs in the body, but the cells of patients with myocardial infarction are incapable of treating the same disease. like cells of healthy young people because these cells are aging and exposed to factors that lead to heart attack, our strategy is to "rejuvenate" stem cells by adding add copies of the genetic gene needed for regeneration, so they can better stimulate the healing of heart damage, reduce scars and restore the heart's ability to pump, say Another way is to help the patient's heart heal itself. "

According to Dr. Stewart, the experiment will determine whether stem cells, especially genetically altered cells, can help treat patients with severe myocardial infarction. .

The hearts of these patients were severely compromised, the scars caused the heart to become weaker, enlarged and put patients at risk of heart failure, sudden death, chronic diseases and premature death. .

New therapies are expected to improve healing of heart damage, reduce scarring and promote heart muscle function. This is an ambitious and internationally interested test
