Stem Cell Therapy for Myocardial Infarction 2001–2013 Revisited

Stem cell therapy for ischemic heart disease was an emerging concept in the early 2000s. First hopes were largely overshadowed by rather inconsistent results in human trials conducted in the middle of the decade. We aimed at investigating how the field of stem cell research expanded worldwide over the years using scientometric methods. We performed a PubMed inquiry and screened a total of 2609 publications dealing with stem cell therapy for myocardial infarction in the years 2001–2013. Density equalizing maps were used to visualize important centres of stem cell research worldwide. This systematic bibliometric study revealed an increasing research interest in the field of stem cell research in the context of ischemic heart disease over the last decade. Though some of the large human trials failed to show significant effects of stem cell therapy, especially basic science represents an ever growing field that evolved promising new concepts over the last couple of years. The scientific principle of protective paracrine mediators released from transplanted stem cells seems to bear great potential for future cell-free therapeutic use. However, further mechanistic insights are needed before transition from bench to bedside should be attempted, taking the lessons learned from previous studies into account.
