Following myocardial infarct, cellular therapy is a potential approach to repopulate the injured myocardium, to treat heart failure and restore cardiac function. The purpose of this study is to assess the safety, feasibility and efficacy of intramyocardial delivery of selected autologous CD133+ bone marrow stem cells at time of coronary artery bypass grafting in patients with chronic ischemic cardiomyopathy.
CD133+ are well-characterized distinct early progenitor group of stem cells that possess high engraftment, pluripotent and angiogenic capacity and proved to be valuable for cardiac repair by promoting neovascularization, inhibition of apoptosis and cardiomyogenesis.
Our proposed research protocol involves patients with chronic ischemic heart disease and left ventricular dysfunction undergoing coronary artery bypass grafting (CABG). In this phase II clinical trial, prospective, randomized, 2 arm, double-blind, placebo-controlled study, we will assess the safety, feasibility and functional effect of intra-myocardial injection of highly selected autologous CD133+ bone marrow stem cells to placebo.
Allocation: Randomized, Control: Placebo Control, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Despite advance in off-pump coronary artery bypass (OPCAB) grafting, there are large debating issues regarding survival benefit between OPCAB and on-pump coronary artery bypass grafting (CABG). The...
Knowledge of the association between time and causes of death after coronary artery bypass grafting is sparse. We examined short- and long-term mortality and cause of death in patients undergoing coro...
Coronary artery bypass grafting remains a viable and successful option for treating high-grade coronary artery stenosis. The postoperative recovery is individual for each patient, but when following l...
Comparative outcomes of coronary-artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) for left main coronary artery (LMCA) disease were previously reported. However, data on very...
Coronary artery bypass grafting (CABG) without cardiopulmonary bypass (off-pump CABG) may reduce severe adverse events including stroke.
Surgical therapy of ischemic coronary artery disease achieved by grafting a section of saphenous vein, internal mammary artery, or other substitute between the aorta and the obstructed coronary artery distal to the obstructive lesion.
Abdominal artery that follows the curvature of the stomach. The right gastroepiploic artery is frequently used in CORONARY ARTERY BYPASS GRAFTING; MYOCARDIAL REVASCULARIZATION, and other vascular reconstruction.
Coronary artery bypass surgery on a beating HEART without a CARDIOPULMONARY BYPASS (diverting the flow of blood from the heart and lungs through an oxygenator).
Direct myocardial revascularization in which the internal mammary artery is anastomosed to the right coronary artery, circumflex artery, or anterior descending coronary artery. The internal mammary artery is the most frequent choice, especially for a single graft, for coronary artery bypass surgery.
Inferior and external epigastric arteries arise from external iliac; superficial from femoral; superior from internal thoracic. They supply the abdominal muscles, diaphragm, iliac region, and groin. The inferior epigastric artery is used in coronary artery bypass grafting and myocardial revascularization.
Osteoporosis is a disease in which the bones become extremely porous, are subject to fracture, and heal slowly, occurring especially in women following menopause and often leading to curvature of the spine from vertebral collapse. Follow and track&n...
