Abstract
in English, Spanish

Evolutionary medicine studies the role of evolution in health problems. Diseases are considered as phenotypes generated by the expression of sets of genes and a complex interplay with the environment. The main mechanisms involved in evolutionary medicine are antagonistic pleiotropy, ecological antagonistic pleiotropy, atavisms and heterochrony. Antagonistic pleiotropism refers to genes that are beneficial during certain stages of development but become detrimental in others. Ecological antagonistic pleiotropy refers to the misadaptation to current lifestyle conditions which are different from those in which humans evolved. These mechanisms participate in the development of congestive heart failure, hypertension and atherosclerosis. Atavistic conditions or genes are expressed in our ancestors but have remained silent during evolution being suddenly expressed without an apparent cause during the appearance of a disease is another mechanism in evolutionary cardiology. The change in the heart metabolism from fatty acid to glucose dependent can be considered as an atavistic condition that appears in the heart after a stroke and may underlie impaired cardiomyocyte regeneration. Heterochrony is the expression of genes that cause the appearance of traits at a different timing during development and is therefore related to atavisms. Evolutionary medicine explains the interactions of pathogens and the host in infectious diseases where the cardiac tissue becomes a target. Mechanisms involved in evolutionary medicine participate in the generation of diseases and may be approached experimentally. Therefore, to better understand health problems and therapeutical approaches, an evolutionary medicine approach in experimental medicine may prove useful.

La medicina evolutiva estudia el papel de la evolución en los problemas de salud. Las enfermedades son fenotipos generados por la expresión de genes y una interacción compleja con el medio ambiente. Los principales mecanismos implicados son la pleiotropía antagonista, la pleiotropía antagonista ecológica, los atavismos y la heterocronía. El pleiotropismo antagonista se refiere a situaciones donde los genes que son beneficiosos durante ciertas etapas del desarrollo resultan perjudiciales en otras. La pleiotropía antagonista ecológica se refiere a la mala adaptación a las condiciones de vida actuales, que difieren de aquellas en las que los humanos evolucionaron. Estos mecanismos participan en el desarrollo de insuficiencia cardiaca congestiva, hipertensión y aterosclerosis. Las condiciones o genes atávicos fueron características que se expresaron en nuestros antepasados pero han permanecido silenciadas durante la evolución, expresándose repentinamente durante una enfermedad; un ejemplo es el cambio metabólico en el corazón de dependiente de ácidos grasos a dependiente de glucosa en condiciones de hipoxia que aparece después de un infarto y puede subyacer a la dificultad de la regeneración de los cardiomiocitos. La heterocronía es la expresión de genes que provocan la aparición de rasgos en un momento diferente durante el desarrollo. La medicina evolutiva también explica las interacciones entre los patógenos y el huésped en enfermedades infecciosas. Los mecanismos implicados en la medicina evolutiva participan en la generación de enfermedades y pueden abordarse experimentalmente. Por tanto, la medicina experimental puede enriquecer la medicina evolutiva y el origen de muchos problemas de salud.
