Bone marrow cells treat heart symptoms

Injecting bone marrow stem cells into the damaged heart can help alleviate angina symptoms in patients suffering from a chronic form of cardiovascular disease. 

Myocardial ischemia is a chronic condition in which long-term reduced blood flow to certain areas of the heart results in oxygen deprivation to the heart muscle and inadequate removal of toxic metabolites. 

According to a study published in the Journal of the American Medical Association, inserting bone marrow cells into the damaged areas of the heart is associated with modest improvements in blood flow to the heart muscle and in overall heart function. 

Stem cell infusion improves heart's ability to pump blood with each contraction, leading to greater improvements in the patient's ability to exercise and their quality-of-life. 

Scientists concluded that bone marrow stem cell therapy is a safe and feasible method in treating patients with ischemic heart disease.
