UW launches study testing adult stem cells for heart damage repair

re encouraging," Raval says. "Subjects reported feeling better with reductions in chest pain and improved exercise capacity during the early stage of the trial. That's encouraging to us."

Coronary artery disease is the most common form of heart disease and is the leading cause of death in the United States. This condition occurs when the coronary arteries and the smaller vessels that supply oxygen-rich blood to the heart muscle become narrowed or blocked by plaque deposits and blood clots. Poor blood flow and blood clots "starve" and injure the heart muscle.

The American Heart Association estimates that every year, between 125,000 and 250,000 individuals with coronary artery disease develop chronic myocardial ischemia (CMI), one of the most severe forms of coronary artery disease, which can cause unstable angina, heart attacks and progressive heart failure when adequate blood flow is not restored. CMI develops when the coronary arteries become so diseased that they limit the flow of blood to the heart and send small blood clots downstream, blocking the small blood vessels in the heart.

These blockages can result in a series of mini-heart attacks that, while they may be too small to notice at the time, in aggregate cause significant long-term damage to the heart muscle and disability to the patient. While cardiologists can restore blood flow in some cases, the heart muscle can be irreversibly damaged, leading to significant disability, progressive heart failure and often death.
