Mesenchymal stem cells from bone marrow and umbilical cord for treating cardiovascular disease

Las células madre (CM) internacionalmente se dividen en embrionarias o fetales y somáticas, en dependencia de su origen. Las CM embrionarias son células pluripotenciales que generan todo tipo de células del organismo y no se emplean por problemas éticos y de lesgilaciones vigentes que prohíben su uso, además de la oposición de la iglesia. Las células somáticas, por el contrario, son las que se usan y ellas son multipotenciales, pero teóricamente solo generan un tipo de tejido específico

Stem cells (CM) are internationally divided into embryonic or fetal and somatic, depending on their origin. The embryonic CMs are pluripotent cells that generate all types of cells of the organism and are not used for ethical problems and current infractions that prohibit their use, in addition to the opposition of the church. Somatic cells, on the other hand, are the ones that are used and they are multipotential, but theoretically they only generate a specific type of tissue

Left ventricular non-compaction cardiomyopathy: outlook and cardiac arrhythmias

Las miocardiopatías constituyen un grupo importante y heterogéneo de enfermedades del miocardio asociadas a disfunción mecánica, eléctrica, o ambas. El ventrículo izquierdo no compacto es una miocardiopatía familiar de etiología incierta de la que se desconocen sus exactas incidencia y prevalencia. Se caracteriza por un aumento en la masa trabecular del VI en contraste con una fina capa epicárdica compacta que puede visualizarse con técnicas de imagen que confirman el diagnóstico. En este artículo se describen la clasificación de MOGE(S) para las miocardiopatías, los trastornos electrocardiográficos que pueden encontrarse en pacientes con ventrículo izquierdo no compacto, el papel de la estimulación eléctrica programada del corazón y otros aspectos de interés de esta enfermedad. Además, se presentan algunos trastornos electrocardiográficos demostrativos (criterios de Stollberger y Jenni) encontrados en pacientes afectados

Cardiomyopathies are an important and diverse group of myocardial diseases associated with mechanical, electrical, or both dysfunctions. The left ventricular (LV) non-compaction is a familial cardiomyopathy of uncertain etiology, whose exact incidence and prevalence are unknown. It is characterized by an increase in the trabecular mass of the LV in contrast to a thin compact epicardial layer that can be visualized with imaging techniques that confirm the diagnosis. In this article is described the classification of MOGE (S) for cardiomyopathies, electrocardiographic disorders that can be found in patients with left ventricular non-compaction, the role of programmed electrical stimulation of the heart and other aspects of interest of this disease. In addition, some demonstrative electrocardiographic disorders (Stollberger and Jenni criteria) found in affected patients are presented

Cardiotoxicity induced by chemotherapy

El cáncer es un problema de salud pública de gran envergadura en el mundo. La quimioterapia está indicada en varias fases del tratamiento antineoplásico ya sea como terapia neoadyuvante, adyuvante o paliativa. Uno de los efectos secundarios más preocupantes generados por la quimioterapia es la cardiotoxicidad, y uno de los principales síntomas es el fallo cardíaco secundario a un daño a nivel del miocardio por la toxicidad directa e indirecta de las terapias antineoplásicas. El objetivo del presente artículo es realizar una revisión del estado del arte de la cardiotoxicidad inducida por quimioterapia, además de hacer una síntesis de los diferentes efectos cardiotóxicos, mecanismos de cardiotoxicidad y métodos que se han desarrollado para su diagnóstico y prevención

Cancer is a major public health problem in the world. Chemotherapy is indicated in several phases of the antineoplastic treatment, either as neoadjuvant, adjuvant or palliative therapy. One of the most worrisome side effects generated by chemotherapy is cardiotoxicity, and one of the main symptoms is heart failure, secondary to damage to the myocardium due to the direct and indirect toxicity of antineoplastic therapies. The objective of this article is to review the state of the art of the chemotherapy-induced cardiotoxicity, as well as to synthesize the different cardiotoxic effects, cardiotoxic mechanisms and methods that have been developed for its diagnosis and prevention
