- Patients who are currently participating or have completed their participation in a clinical trial within a period of less than 3 months or who have participated in a clinical trial of Advanced Therapies (cell therapy, gene therapy or tissue engineering) at any time before and has been assigned to an experimental group.
- Patients with malignant or pre-malignant tumors.
- Patients in whom an MRI cannot be performed because they carry devices incompatible with the MRI (prostheses, defibrillators, pacemakers, etc).

5. Study Description
Brief Summary
Clinical trial phase III, prospective, controlled, randomized, open.
We hypothesize work that patients with chronic coronary occlusion and poor myocardial viability who failed to recover ventricular function after subjecting coronary revascularization with new techniques of recanalization, could achieve an improvement of ventricular function if given further regenerative treatment with mononuclear cells from autologous bone marrow.
To test this hypothesis we designed a prospective, randomized clinical trial in patients with recanalized chronic occlusions and ventricular dysfunction.
Detailed Description
This is a randomized, open label prospective clinical trial in which all patients diagnosed with chronic coronary occlusion in the Cardiology Department of Hospital Reina Sofía in Cordoba and Hospital Puerta del Mar in Cadiz, who meet inclusion criteria and none of the exclusion shall include and express their accordance with trial participation by signing the informed consent.
66 patients who did not improve ventricular function measured by Magnetic resonance at least 3 months after revascularization of chronic coronary occlusion will be included . The 66 patients will be randomized in one to one ratio to an intervention group that received bone marrow mononuclear cells by intracoronary autologous (0.5 to 1 x 10 9 total cells) and a control group who receive only conventional medical treatment. The two groups of patients will be followed, in the clinical trial, for 6 months. Once the test is complete, they will follow according to standard clinical practice of Cardiology hospital for at least 24 months.
Patients will be assessed by clinical and Magnetic resonance methods. All patients will be medically treated similarly with ACE inhibitors or angiotensine 1 receptor (AT1) receptor antagonists of angiotensin II, beta-blockers and diuretics.
The main objective os the study is to determine the efficacy of intracoronary infusion of mononuclear cells from autologous bone marrow in patients with chronic coronary occlusion previously revascularized with stents in terms of improved ventricular function determined by magnetic resonance.
Secondary objectives of the study are:
To confirm, in view of the obtained results, the suitability of the proved protocol for the treatment of chronic coronary occlusion.
To study changes in functional class (I-IV NYHA) of these patients compared with the control group.
To evaluate the safety of treatment, the analysis of possible cardiac events during the 6-month follow-up in the clinical trial and 24 months of additional clinical follow-up (death, myocardial infarction, repeat revascularization) compared with the control group.
