Ixmyelocel-T for patients with ischaemic heart failure: a prospective randomised double-blind trial

This was a prospective, randomized, double-blind, placebo-controlled trial - which is considered the gold standard for clinical research. Patients used their own stem cells to regenerate damaged heart muscle whose heart failure was caused by blocked coronary arteries (ischemic), showing fewer heart-related complications and better symptoms compared to placebo.
