Este estudio tiene como objetivo evaluar la eficacia y seguridad de la terapia combinada de cardiomioplastia celular con el factor estimulante de colonias de granulocitos en pacientes con cardiopatía isquémica, y explorar posibles diferencias entre la vía de implantación.

Metodología

Se hizo un estudio de «antes y después» para datos longitudinales en el que se compararon variables ecocardiográficas y número de MET alcanzados en la prueba de esfuerzo antes, dos, seis y doce meses después del procedimiento; así mismo, se evaluaron la mortalidad y los efectos adversos de la terapia. Se exploraron diferencias en los resultados de acuerdo con la vía de implantación intracoronaria vs. epicárdica.

Resultados

Se incluyeron dieciocho pacientes, 62,3% hombres, cuya edad promedio fue 49,4 ± 11,7 años y la fracción de eyección promedio fue 31% ± 0,04. La implantación se realizó por vía intracoronaria en doce pacientes y por vía epicárdica en seis. La mediana de fracción de eyección antes de la implantación de las células fue de 30% con un rango intercuartil de 28%-35% y la media de los MET fue de 6 con un rango intercuartil de 5-7; ambas variables, al igual que los volúmenes ventriculares de fin de diástole y sístole se incrementaron de forma significativa después del procedimiento, con tendencia a un mayor incremento de la fracción de eyección en el grupo de pacientes cuya vía de implantación fue la epicárdica en comparación con la vía intracoronaria; sin embargo, el número de pacientes en cada subgrupo impidió hacer análisis definitivos. Un paciente tuvo infección de la herida quirúrgica y tres murieron dos meses después de la implantación (uno de shock séptico y dos de shock cardiogénico).

Conclusión

En nuestro medio es factible realizar terapia combinada con cardiomioplastia celular y factor estimulante de colonias de granulocito; este es un procedimiento seguro con el que se obtiene una mejoría sostenida de la fracción de eyección y los MET más allá de los beneficios que se logran con la revascularización y la terapia farmacológica óptima.

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.
