Brief Summary

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

This is a prospective, randomized, placebo-controlled, double blind safety and efficacy clinical trial.

Detailed Description

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

To assess the safety and efficacy of Adipose-Derived Regenerative Cells (ADRCs) delivered via an intramyocardial route in the treatment of chronic ischemic heart disease in patients who are not eligible for percutaneous or surgical revascularization.
