SENIOR, Juan M et al. Comparison of efficacy and safety of combined therapy of cellular cardiomyoplasty and granulocyte colony stimulating factor in patients with ischemic cardiomyopathy in two routes of implantation. Rev. Colom. Cardiol. [online]. 2011, vol.18, n.2, pp.111-118. ISSN 0120-5633.

The objective of this study is to assess efficacy and safety of combined therapy of cellular cardiomyoplasty and granulocyte colony stimulating factor in patients with ischemic cardiomyopathy and explore possible differences between the implantation routes. METHODOLOGY: we performed a before and after study for longitudinal data comparing echocardiographic variables and number of Met achieved in the stress test before and at two, six and twelve months after the procedure. Likewise, mortality and adverse therapy effects were evaluated. Differences in the results were analyzed according to the intracoronary vs. epicardiac route of implantation. RESULTS: eighteen patients were included; 62,3% men, with mean age 49.4 ± 11,7 years. Mean ejection fraction was 31% ± 0,04. In twelve patients implantation was performed by intracoronary route and in six by epicardiac route. Mean ejection fraction before cell implantation was 30% with an interquartil range (IQR) of 28-35%, and MET average was 6 with an interquartil rage of 5-7. Both variables as well as end-systolic and end-diastolic volumes increased significantly after the procedure, with a tendency to greater increase in ejection fraction in the group of patients whose route was epicardial implantation compared with intracoronary route; however, the number of patients in each subgroup prevented to make a definitive analysis. One patient had surgical wound infection and three died two months after implantation (one of septic shock and two of cardiogenic shock). CONCLUSION: in our environment the performance of combination therapy with cellular cardiomyoplasty and granulocyte colony stimulating factor is feasible. This is a safe procedure that achieved a sustained improvement in ejection fraction and MET beyond benefits achieved with revascularization and optimal pharmacological therapy.
