About

Myocardial infarction causes necrosis of myocardial cells and reduces cardiac function. Today, there are treatments such as primary angioplasty and thrombolysis that are effective in limiting cell death after acute myocardial infarction. However, the post-infarct scar often conditions a global ventricular remodeling that can evolve clinically towards heart failure and in more advanced stages the only therapy that completely restores cardiac function is heart transplantation.

Mesenchymal stem cells are multipotent cells found from embryonic mesoderm and found in all tissues. In the field of cardiac regeneration, studies have shown a certain degree of benefit when treated with MSCs from different origins. Our approach is based on a decellularized matrix that carries the cells directly over myocardial infarction.

Full description

Myocardial infarction causes necrosis of myocardial cells and reduces cardiac function. Today there are treatments such as primary angioplasty and thrombolysis that are effective in limiting cell death after acute myocardial infarction. However, the post-infarct scar often conditions a global ventricular remodeling that can evolve clinically towards heart failure and, in more advanced stages, the only therapy that completely restores cardiac function is heart transplantation.

Experimental studies are evaluating new therapeutic approaches based on tissue engineering for myocardial regeneration. Cardiac tissue engineering attempts to create functional tissue constructs that can restore the structure and function of damaged myocardium.

Mesenchymal stem cells (MSCs) are multipotent cells that develop from embryonic mesoderm and are found in all structural tissues of the body.

In the field of cardiac regeneration, studies have shown a certain degree of benefit when treated with MSCs from different origins. The investigators approach is based on a decellularized matrix that carries the cells directly over myocardial infarction.

Among the different types of MSC currently available, the investigators propose the use of those derived from the connective tissue surrounding the great vessels (2 arteries and one vein) of the umbilical cord called Wharton's gelatin (MSC, WJ) whose immunomodulatory properties are described extensively in the literature. These MSC, WJ cells have a PEI approved by the Spanish Agency for Medicines and Healthcare Products (AEMPS) (PEI 16-017) that guarantees an optimal manufacturing process for a clinical trial.

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Double Blind

---

12 participants in 2 patient groups

Experimental group

Experimental group

Description:

The patient will undergo surgery by sternotomy to perform the surgical revascularization of the arteries candidates for revascularization. In addition, the matrix-cell (PeriCord) construct will be placed on the ischemic area of the non-candidate revascularization area and will be fixed using surgical glue. PeriCord: Expanded and cryopreserved allogeneic umbilical cord Wharton´s jelly-derived adult mesenchymal stem cells colonized on human pericardial matrix .

Treatment:

Combination Product: PeriCord: Expanded and cryopreserved allogeneic umbilical cord Wharton´s jelly-derived adult mesenchymal stem cells colonized on human pericardial matrix.

Control group

Active Comparator group

Description:

The patient will undergo surgery by sternotomy to perform the surgical revascularization of the arteries candidates for revascularization. No additional procedure will be performed.
