Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of the present study is to investigate safety and efficacy of intramyocardial implantation of a novel mesenchymal precursor cell type (iMP) in patients with ischemic cardiomyopathy at the time of coronary artery bypass grafting.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study aims to investigates in situ cardiac regeneration utilizing precision delivery of a novel mesenchymal precursor cell type (iMP) during coronary artery bypass surgery (CABG) in patients with ischemic cardiomyopathy (LVEF \< 40 %). Preoperative scintigraphy imaging (SPECT) will be used to identify hibernating myocardium not suitable for conventional myocardial revascularization for iMP implantation. iMP cells will be implanted intramyocardially in predefined viable peri-infarct areas that show poor perfusion, which could not be grafted due to poor target vessel quality. Postoperatively, SPECT will be used to identify changes in scar area.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Stem cells implantation

Patients with severe coronary artery disease and chronic ischemic cardiomyopathy with a LVEF ≤40% who are scheduled for elective CABG according to accepted guidelines. Additional criteria include the following: age \<75 years, history of myocardial infarction (not less than 14 days before the procedure), LVEF ≤40 % assessed with echocardiography, and a distinct area of dyskinetic or akinetic left ventricular myocardium corresponding with the infarct localization.
