Resumen

Las enfermedades cardiovasculares son la principal causa de muerte a nivel mundial. Para el 2019, se estimó que el 32% de todas las muertes a nivel mundial se dieron por esta causa. Este fenómeno se repite a nivel nacional, de acuerdo al Instituto Nacional de Salud, es la principal causa de muerte con un 23.5% de las muertes en el país. Para su diagnóstico, las imagenes ecocardiografía son la primer elección. La técnica permite evaluar las estructuras cardíacas y su función en la mayoría de ambientes clínicos. La ecocardiografía cuenta con diferentes modalidades que tomando ventaja de principios claves de ultrasonido permiten obtener modalidades como el análisis Doppler y técnicas de rastreo de patrones speckle, permitiendo a su vez evaluar el flujo de la sangre en puntos clave, así como el movimiento del músculo cardíaco. Además de los diferentes modos de imagen, de la ecografía se pueden obtener diferentes medidas para una evaluación completa: grosor de las paredes ventriculares, dimensiones de la cámara cardíaca, volúmenes de los ventrículos, velocidades de flujo y fracciones de eyección. Sin embargo, estas técnicas están dirigidas a ver las características de la sangre y del músculo por separado.

Dadas estas razones y recordando que la función cardíaca es dependiente de interacciones entre tejidos de diferentes características (sangre y músculo), así como de la construcción misma del ventrículo (que explica varios elementos del movimiento cardíaco). Este trabajo propone explorar la evaluación de la función cardíaca en términos de la interacción dinámica entre estos tejidos, pues puede aportar información complementaria a los indicadores de evaluación actuales.
