Brief Summary

Coronary artery disease (CAD) is a common disorder that can lead to heart failure. Not all people with CAD are eligible for today's standard treatments. One new treatment approach uses stem cells-specialized cells capable of developing into other types of cells-to stimulate growth of new blood vessels for the heart. This study will determine the safety and effectiveness of withdrawing stem cells from someone's bone marrow and injecting those cells into the person's heart as a way of treating people with CAD and heart failure.

Detailed Description

Coronary artery disease (CAD), a disease in which blood vessels become clogged by a build-up of plaque, is the leading cause of heart failure, a condition in which the heart can no longer pump enough blood to the rest of the body. People with heart failure caused by CAD are said to have ischemic cardiomyopathy. Normal treatment for CAD involves coronary artery bypass grafting (in which a vein from another part of the body is grafted around an artery that has become blocked) or coronary angioplasty and stent placement (in which a blocked artery is opened and a small tube is placed to keep the artery open). However, some people with ischemic cardiomyopathy, such as those with substantial scar tissue on the heart wall or those with a particular heart structure, may not be eligible for these treatments. An alternative treatment being developed is therapeutic angiogenesis, which involves stimulating the growth of new blood vessels. Recent research has shown that withdrawing stem cells from bone marrow and implanting the cells into heart tissue may be an effective way to achieve therapeutic angiogenesis. This study will determine the safety and effectiveness of using stem cells to stimulate new blood vessel growth in the hearts of people with ischemic cardiomyopathy.

Participation in this study, including follow-up visits and phone calls, will last 60 months. Participants will first undergo 3 to 4 days of screening procedures that will include a physical examination, multiple lab tests, and a battery of tests on heart health. Next, participants will be randomized to receive either active stem cell injections or placebo injections. The injections and related procedures will be performed in a hospital and last approximately 72 hours. During this time, participants in both groups will first undergo a bone marrow aspiration procedure. Participants receiving active stem cells will also undergo NOGA electromechanical cardiac mapping, which involves inserting a monitoring device through a catheter and into the heart. Injections of stem cells will then be made to 15 damaged sites on the heart through a special catheter. Participants receiving placebo injections will receive 15 injections of an inactive, saline-based solution. After the injection procedures, all participants will undergo two echocardiograms, an electrocardiogram, blood tests, and overnight monitoring in a telemetry unit.

After the hospital stay, all participants will attend five study visits that will occur 1 week and 1, 3, 6, and 12 months after the injection procedures. At all study visits, participants will undergo an electrocardiogram, lab tests, and a review of adverse health events. On all but the last study visit, participants will have cardiac markers assessed, and they will wear a 24-hour Holter monitor to track heart activity. At the last three visits, participants will also complete quality of life questionnaires. All participants will then receive four follow-up telephone calls that will occur 2, 3, 4, and 5 years after the injection procedures.
