Does cardiopoietic index predict heart repair fitness of patient-derived stem cells? Context: Stem cell therapy shows promise for regeneration in heart disease, yet interpatient variability challenges implementation into practice. To establish a biomarker profile, predictive of reparative potential in patient-derived progenitors, human mesenchymal stem cells were isolated from patients undergoing coronary artery bypass grafting. Stem cell delivery postinfarction translated into divergent benefit, distinguishing reparative from nonreparative populations. While the nonreparative subtype was characterized by low expression of cardiac transcription factors, reparative human mesenchymal stem cells demonstrated high expression of cardiac transcription factors.

This index of factors (cardiopoietic index) was found sensitive and specific in predicting impact of stem cell benefit on left ventricular function. The cardiopoietic index thus offers a tool to screen stem cell fitness for heart repair prior to intervention. Final Decision: yes
