Stem cell therapy for cardiovascular diseases (CVDs) is a type of heart disease treatment that uses mesenchymal stem cells (MSCs) to repair and regenerate damaged heart tissue. Adult stem cells are injected into heart tissue, where they can differentiate into various types of cardiac cells. These new cells have the ability to regenerate the heart and heal damage caused by heart disease or cardiac events (such as heart attacks). There is substantial evidence that stem cell therapy can improve overall heart function, even in patients suffering from severe cardiovascular disease. It is a promising alternative for patients with heart conditions who are seeking effective and less invasive options.
