Clinical Application of VO 2 Max VO 2 Max reflects the degree of the impairment in: Ventricular function (pumping capacity), Vascular function (O 2 delivery), Skeletal muscle metabolic capacity (O 2 utilization). Pts with VO 2 Max ≤ 14 ml kg -1 min -1 had a 1 year survival rate of only 47%.

26. Conclusions This is the first in man transendocardial injection of autologous adipose derived stem cells (ADRCs) in patients with chronic ischemic heart disease. Autologous ADRCs harvesting and injection was safe in these severely compromised patients. There were no peri- procedural complications and there was no evidence of cell therapy related adverse events (arrhythmia, MACCE). Improvement in functional capacity as demonstrated by METS and VO 2 Max and a decrease of Infarct size as measured by MRI in ADRCs treated patients suggest potential efficacy which should be explored in a larger trial.
