BACKGROUND: We investigated the effects of intracoronary transplantation of CD34(+) cells on myocardial perfusion in patients with non-ischemic dilated cardiomyopathy (DCM).
METHODS AND RESULTS: We enrolled 21 patients with DCM (LVEF <40%, NYHA class III) who underwent peripheral stem cell mobilization with G-CSF. CD34(+) cells were collected via apheresis. Patients underwent myocardial perfusion imaging and CD34(+) cells were injected in the coronary artery supplying viable segments with reduced myocardial perfusion and regional dysfunction. Myocardial perfusion imaging was repeated 6 months later. Clinical response to stem cell therapy was pre-defined as a change in LVEF >5%. The majority of patients were men (81%) with an age of 53±9 years, LVEF of 25±5%, and 6-minute walking distance of 354±71 m. Myocardial perfusion defects at rest were observed in 86% of patients and were more common in the LAD territory (50%). At 6 months follow-up, there was a significant improvement in rest myocardial perfusion scores (6.3±5.8 vs. 3.1±4.3, P<0.001), LVEF (25±7% vs. 29±8%, P=0.005), and 6-minute walking distance (354±71 m vs. 404±91 m, P<0.001). Responders to stem cell therapy had lower summed rest perfusion score (SPS) at both baseline (3.2±3.0 vs. 9.1±6.3, P=0.015) and follow-up (1.0±1.5 vs. 5.0±5.1, P=0.028).
CONCLUSIONS: CD34(+) cell transplantation may lead to improved myocardial perfusion in patients with non-ischemic DCM. Patients with less severe myocardial perfusion defects at baseline may have an increased likelihood to respond to intracoronary CD34(+) cell transplantation.
