Brief Summary:
The aim of this study is to evaluate if the intracoronary infusion of autologous bone-marrow derived CD133+ endothelial precursor cells is able to promote neovascularization and to improve myocardial perfusion and contractility in patients with refractory coronary heart disease, characterized by poor response to standard coronary interventions, severe impairment of the quality of life, and poor prognosis.

Condition or disease Intervention/treatment Phase
Coronary Artery Disease Procedure: Intracoronary Infusion of CD133+ Cells Phase 1 Phase 2

Detailed Description:
Refractory Coronary Artery Disease is a significant cause of mortality and decreased quality of life. Intracoronary infusion of CD133+ progenitor cells is a viable treatment option for patients with this condition. After clinical and laboratory evaluation, 50-100 ml of bone marrow will be obtained by bone marrow aspiration from the posterior iliac crest under local anesthesia. From this sample, CD133+ endothelial progenitor cells will be isolated, purified and packed within the next 12 hours of extraction, and resuspended in 30 ml saline solution. The patient will undergo coronary catheterization for selection of the target obstructed artery for cell infusion, which will be performed using a balloon catheter under hemodynamic monitoring. Once concluded, the patient will be transferred to intermediate care unit for post-interventional observation for approximately 24 hours before being released. Ambulatory follow-up will be performed at specific intervals to determine efficacy and safety of this intervention by clinical and laboratory examination, including imaging and cardiac function studies.

Intervention Details:
  • Procedure: Intracoronary Infusion of CD133+ Cells
    Single intracoronary infusion of a suspension consisting of 30 ml saline solution containing at least 1 million CD133+ endothelial precursor cells.

Primary Outcome Measures :
  1. Increased regional and global myocardial contractility measured by low-dose dobutamine echocardiography/MRI and increased myocardial perfusion measured by adenosine nuclear stress testing. [ Time Frame: Base-line, 3, and 6 months. ]

Secondary Outcome Measures :
  1. Improvement in the heart failure functional class measured by NYHA and CCS classification tests. [ Time Frame: Base-line, 3, and 6 months ]
  2. Changes in the score of the "Minnessota living with heart failure score". [ Time Frame: Base-line, 3, and 6 months. ]
  3. Functional heart changes measured by spiroergometry. [ Time Frame: Base-line, 3, and 6 months. ]
  4. Reduction in the consumption of medicines for the heart ailment (nitrates, diuretics, etc.). [ Time Frame: Base-line, 3, and 6 months. ]
  5. Safety and compatibility through evaluation of adverse events (death, supraventricular and ventricular arrhythmias, brain/peripheral ischemic events, myocardial infarct, malignancies, etc.). [ Time Frame: Base-line, 3, and 6 months. ]
