Study Aim

This study aims to evaluate the safety and effectiveness of Revascularization Surgery using Wharton's Jelly-derived Mesenchymal Cells and an Epicardial Extracellular Matrix Patch in improving heart function for individuals with Ischemic Cardiomyopathy, focusing on improvements in diastolic and systolic volumes, left ventricular ejection fraction, and reduction in ventricular arrhythmias.

Actual date on which the first participant was enrolled.

This clinical trial is a treatment study for individuals who have previously experienced a heart attack and have a viable area of heart muscle that requires bypass surgery. The study aims to test the effectiveness of coronary revascularization surgery combined with two different treatment approaches. One approach involves the placement of an extracellular matrix patch and injection of a cell culture medium. The other approach involves the placement of an extracellular matrix patch seeded with Wharton's Jelly-derived Mesenchymal Cells (WJ-MSCs) and injection of WJ-MSCs around the area of the heart attack. The goal is to see if these treatments can improve heart function and reduce complications associated with heart disease. The study will include 40 participants, with 20 in each treatment group over a period of 36 months. Participants will be randomly assigned to one of the two treatment groups. The treatment allocation will be determined by a random number generator and will only be known by the tissue bank providing the treatment materials. The study will measure the improvement in final diastolic and systolic volumes, left ventricular ejection fraction (LVEF), left ventricular viability, and the incidence of ventricular arrhythmias. These measurements will be taken using transthoracic echocardiography and cardiac MRI.

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details

40 patients to be enrolled

Total number of participants that the clinical trial aims to recruit.

Treatment Study

These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.
